    119 T.C. No. 4
    UNITED STATES TAX COURT
    EDWARD A. ROBINSON III AND DIANA R. ROBINSON, Petitioners v.
    COMMISSIONER OF INTERNAL REVENUE, Respondent
    Docket No. 9574-99.            Filed September 5, 2002.
    P-H operated a law practice as a sole proprietorship at
    all relevant times. R audited Ps’ 1987 joint tax return and
    made several adjustments to the Schedules A and C attached
    to this tax return. Ps agreed to R’s adjustments and the
    resulting deficiencies and additions to tax. In 1994, R
    seized real property that Ps owned; in 1995, R sold the
    property and applied the proceeds to Ps’ underpayment of
    their 1987 income tax liability and interest thereon. On
    Schedule C of their 1995 joint tax return, Ps deducted the
    1987 underpayment interest that had been thus paid.
    1. Held: Insofar as sec. 1.163-8T, Temporary Income Tax
    Regs., 
    52 Fed. Reg. 24999
     (July 2, 1987), and sec. 1.163-
    9T(b)(2)(i)(A), Temporary Income Tax Regs., 
    52 Fed. Reg. 48409
     (Dec. 22, 1987), apply under the circumstances herein
    to characterize the 1987 underpayment interest thus paid in
    1995 as not being “interest * * * on indebtedness properly
    allocable to a trade or business” within the meaning of sec.
    - 2 -
    163(h)(2)(A), I.R.C. 1986, and therefore as not being
    deductible under ch. 1, I.R.C. 1986, these regulations are
    valid.
    2. Held, further, Redlark v. Commissioner, 
    106 T.C. 31
    (1996), revd. and remanded 
    141 F.3d 936
     (9th Cir. 1998),
    will no longer be followed.
    3. Held, further, Ps are not entitled to deduct the
    interest they paid in 1995 on account of the underpayment of
    their 1987 income tax liability.
    Charles B. Sklar1, for petitioners.
    Joseph Ineich, for respondent.
    CHABOT, Judge: Respondent determined a deficiency in Federal
    individual income tax for 1995 against petitioners in the amount
    of $29,879.2   The issue for decision is whether petitioners may
    deduct for 1995 the interest they paid in 1995 on their 1987
    Federal individual income tax underpayment.3

    Cheryl R. Frank and Gerald W. Kelly, Jr., appeared on
    petitioners’ behalf at the trial. A few months later, before
    filing any briefs, they moved for leave to withdraw as counsel;
    the Court granted their motion. Later Charles B. Sklar entered
    his appearance and thereafter represented petitioners on brief.
    2
    Of this total, $28,015 is income tax under ch. 1 and
    $1,864 is self-employment tax under ch. 2.
    Unless indicated otherwise, all section and chapter
    references are to sections and chapters of the Internal Revenue
    Code of 1986 as in effect for 1995. The section references in
    table 1, infra, are to this Code as in effect for 1987.

    FINDINGS OF FACT
    Some of the facts have been stipulated; the stipulations and
    the stipulated exhibits are incorporated herein by this
    reference.
    Petitioners Edward A. Robinson III (hereinafter sometimes
    referred to as Edward), and Diana R. Robinson resided in
    Louisiana when they filed their petition in the instant case.
    A.   Edward’s Background
    In 1970, Edward was graduated from Grambling State
    University, cum laude, with a double major in political science
    and English.   In 1971, Edward received a master’s degree in
    criminal jurisprudence from the State University of New York at
    Albany.   In 1975, Edward received his law degree from Rutgers
    University.    Edward also was awarded an honorary LL.D. from World
    University, in Tucson, Arizona.
    After his Rutgers graduation, Edward worked as the chief
    administrator of the Louisiana Justice Department.   Edward
    3
    (...continued)
    “other interest” that was reported on the Schedule C (Profit or
    Loss From Business) attached to their 1995 tax return. The
    $69,617 interest payment was made in respect of petitioners’
    underpayment of their 1987 Federal individual income tax
    liability. The other adjustments that respondent made to
    petitioners’ 1995 return were to petitioners’ Schedule A
    (Itemized Deductions) and to the computation of the self-
    employment tax deduction and the self-employment tax liability
    for Edward A. Robinson III. These adjustments are computational;
    their resolution depends on our determination of the issue for
    decision.
    - 4 -
    resigned from this position and opened his own law practice in
    1979.     Edward’s law practice focused almost exclusively on
    personal injury cases.     At all relevant times, Edward’s law
    practice was operated as a sole proprietorship.
    B.   1987 Return and Audit Thereof
    During 1989, respondent audited petitioners’ 1986 and 1987
    joint tax returns.4
    On their 1987 tax return, petitioners reported $6,274
    interest income and $60,677 net profit from Edward’s law
    practice.     On the 1987 Schedule C, petitioners reported $388,000
    gross receipts, $18,500 cost of goods sold, and $308,823
    deductions, leading to the $60,677 net profit.     On the 1987 Form
    1040, petitioners reported $3,866 chapter 1 income tax, $5,387
    chapter 2 self-employment tax, $502 addition for underpayment of
    estimated tax, and no withholding or other payments, for a total
    of $9,755 owed.     Petitioners timely paid this $9,755.
    Respondent proposed adjustments to petitioners’ 1987 taxable
    income, and a deficiency and additions to tax as shown in table
    1.
    4
    We do not make further findings as to 1986 because the
    parties have stipulated that the $69,617 item which is the basic
    adjustment in the instant case is entirely interest on the
    underpayment of petitioners’ 1987 tax liability.

    Reduction in medical expense deduction, resulting from increase
    in adjusted gross income because of additional income from
    Edward’s law practice.
    3
    Fifty percent of the interest on $83,632.30.
    Petitioners agreed to these proposed changes, and the
    appropriate amounts were assessed.
    Respondent seized certain of petitioners’ property in 1994,
    sold the property in 1995, and in 1995 applied $69,617 of the
    proceeds to petitioners’ interest on the underpayment of their
    1987 tax liability.
    The $69,617 interest payment was not related to any
    liability on petitioners’ 1987 tax return as originally filed, as
    all such liability had been timely paid.    This interest payment
    - 6 -
    was applied only to interest assessed as a result of the 1987
    audit deficiency in tax and additions.    Petitioners deducted this
    $69,617 as “Interest: * * * Other” on line 16b of the Schedule C
    (Edward’s law practice) on their 1995 tax return.
    On their 1995 tax return, petitioners reported $359,915 net
    profit from Edward’s law practice (Sched. C), $1,410 royalty
    income (Sched. E), and a $1,702 loss on sales of business
    property (Form 4797).   On the 1995 Schedule C, petitioners
    reported $523,480 gross receipts, $26,340 cost of goods sold, and
    $137,225 deductions (including the disputed $69,617 other
    interest item), leading to the $359,915 net profit.   On the 1995
    Form 1040, petitioners reported $108,735 chapter 1 income tax,
    $17,228 chapter 2 self-employment tax, $59 addition for
    underpayment of estimated tax, and $110,000 estimated tax
    payments, for a total of $16,022 owed.
    ________________________________
    The $69,617 was interest paid in 1995, but it was not on
    indebtedness properly allocable to Edward’s law practice,
    petitioners’ only relevant trade or business.
    OPINION
    A.   The Parties’ Contentions
    The parties focus their dispute on whether section 163
    prohibits allowance of petitioners’ claimed $69,617 Schedule C
    - 7 -
    interest deduction; in particular whether the interest is “on
    indebtedness properly allocable to a trade or business”, within
    the meaning of section 163(h)(2)(A), and therefore exempt from
    the general disallowance rule of section 163(h).
    Petitioners contend that the $69,617 interest qualifies for
    the exemption from the disallowance rule and that a regulation to
    the contrary is invalid, relying on this Court’s opinions to that
    effect.   In the alternative, they contend that the regulation is
    not an authoritative interpretation of the applicable statutory
    language, the regulation having been issued before the statutory
    language was enacted.
    Respondent relies on the regulation as an authoritative
    interpretation of an ambiguous statute and notes that the Courts
    of Appeals of five different circuits have come to the same
    conclusion.   As to the prior opinions on which we relied in
    invalidating the regulation, respondent’s brief states that “It
    is therefore respondent’s position that pre-section 163(h) case
    law is irrelevant to the resolution of the instant case.”   In the
    alternative, respondent contends that, if we were to conclude
    “that deficiency interest attributable to a trade or business is
    deductible, then an allocation of the deficiency interest in this
    case to the Schedule C adjustments and to the Schedule A
    adjustments for the 1987 year, will be required.”
    - 8 -
    Neither side contends that we should distinguish between the
    factual settings presented in our two prior opinions on this
    subject.   Apart from respondent’s alternative contention as to
    the 1987 Schedule A adjustments, respondent apparently accepts
    that, if the regulations are not valid, then the interest expense
    resulting from the 1987 Schedule C adjustments is properly a 1995
    Schedule C deduction.
    B.   Summary of Conclusions
    We agree with respondent’s primary position and much of
    respondent’s analysis.
    Section 162(a) allows a deduction for “all the ordinary and
    necessary expenses paid or incurred during the taxable year in
    carrying on any trade or business”; this includes interest.
    Section 163(a) allows a deduction for “all interest paid or
    accrued within the taxable year on indebtedness”; this is allowed
    even if the interest would not be deductible under section
    162(a).    Notwithstanding this broad allowance language there are
    statutory limitations on amounts (e.g., sec. 163(d), relating to
    investment interest) and prohibitions (e.g., sec. 163(f),
    relating to registration-required obligations), that override not
    only section 163, but all of chapter 1 (sec. 163(d)(1)) or even
    “any other provision of law” (sec. 163(f)(1)).
    In the instant case we focus on the prohibition in section
    163(h)(1), prohibiting any deduction under chapter 1 for
    - 9 -
    “personal interest”.    The Congress has defined this term
    comprehensively5 in section 163(h)(2), so we focus on the
    specifics of the relevant part of the definition--“properly
    allocable to a trade or business” (sec. 163(h)(2)(A))--rather
    than concepts involved in “personal”.
    Examination of the history of the legislation, both the
    sequence of events and the formal explanations, does not lead to
    any clear answer as to the meaning of the finally adopted
    statutory language.    It is clear, however, that the Congress
    chose language different from the statutory language that had
    been construed in earlier cases.    This strongly suggests that the
    Congress intended a meaning different from the older statutory
    language, but it does not clearly indicate what the Congress
    intended that difference to be.
    It is in this setting that we reach the Treasury
    Regulations--section 1.163-8T, Temporary Income Tax Regs., 
    52 Fed. Reg. 24999
     (July 2, 1987), and section 1.163-9T(b)(2)(i)(A),
    Temporary Income Tax Regs., 
    52 Fed. Reg. 48409
     (Dec. 22, 1987).6
    5
    That is sec. 163(h)(2) provides that “the term ‘personal
    interest’ means”. (Emphasis added.) Compare secs. 64 and 65
    (“the term * * * includes” (emphasis added)).
    6
    Sec. 6232(a) of the Technical and Miscellaneous Revenue
    Act of 1988 (TAMRA 1988), Pub. L. 100-647, 
    102 Stat. 3342
    , 3734-
    3735, added subsection (e) to sec. 7805. Sec. 7805(e)(2)
    provides that “Any temporary regulation shall expire within 3
    years after the date of issuance of such regulation.” Sec.
    7805(e)(2) applies to any temporary regulation issued after Nov.
    (continued...)
    - 10 -
    It is accepted that these regulations, if not invalid, would
    result in our concluding that interest on petitioners’ 1987
    underpayment of Federal income taxes is nondeductible personal
    interest.   We conclude that, taking into account the uncertainty
    as to the meaning of the statute, even as informed by the history
    of the legislation, these regulations constitute a permissible
    interpretation of the statute.   As a result, the regulations are
    not invalid, and so petitioners’ claimed interest expense
    deduction is not allowed under chapter 1.
    C.   Caselaw Setting of the Issues
    We first addressed the validity of section 1.163-8T,
    Temporary Income Tax Regs., 
    52 Fed. Reg. 24999
     (July 2, 1987),
    and section l.163-9T(b)(2)(i)(A), Temporary Income Tax Regs., 
    52 Fed. Reg. 48409
     (Dec. 22, 1987), in Redlark v. Commissioner, 
    106 T.C. 31
    , 34 (1996).   At that time, the Court of Appeals for the
    Eighth Circuit was the only Court of Appeals that had addressed
    the issue, and it concluded that section 1.163-9T(b)(2)(i)(A),
    Temporary Income Tax Regs., supra, is not invalid.   Miller v.
    United States, 
    65 F.3d 687
    , 691 (8th Cir. 1995).   With all due
    respect to the Court of Appeals for the Eighth Circuit, we
    concluded in Redlark v. Commissioner, 
    106 T.C. at 42, 47
    , that
    6
    (...continued)
    20, 1988. TAMRA 1988 sec. 6232(b), 102 Stat. at 3735. The
    regulations herein involved were issued before Nov. 20, 1988, and
    thus the “sunset” provision of sec. 7805(e)(2) does not apply to
    these regulations.
    - 11 -
    both section 1.163-8T, Temporary Income Tax Regs., supra, and
    section 1.163-9T(b)(2)(i)(A), Temporary Income Tax Regs., supra,
    as applied to the facts presented in Redlark were unreasonable.
    Relying on Redlark v. Commissioner, 
    supra,
     we held in Kikalos v.
    Commissioner, 
    T.C. Memo. 1998-92
    , that the interest on the income
    tax deficiencies resulting from the operation of the taxpayer-
    husband’s unincorporated trade or business was deductible under
    section 163(h)(2)(A) because the interest was properly allocable
    to the taxpayer-husband’s unincorporated trade or business.
    The Courts of Appeals for the Ninth and Seventh Circuits
    reversed our decisions in Redlark v. Commissioner, 
    supra,
     and
    Kikalos v. Commissioner, 
    supra,
     respectively, and held that
    section 1.163-9T(b)(2)(i)(A), Temporary Income Tax Regs., supra,
    is a reasonable interpretation of section 163(h).   Kikalos v.
    Commissioner, 
    190 F.3d 791
    , 799 (7th Cir. 1999), revg. 
    T.C. Memo. 1998-92
    ; Redlark v. Commissioner, 
    141 F.3d 936
    , 942 (9th Cir.
    1998), revg. and remanding 
    106 T.C. 31
     (1996).   The Courts of
    Appeals for the Fourth and Sixth Circuits also reached the same
    conclusion.   McDonnell v. United States, 
    180 F.3d 721
    , 723 (6th
    Cir. 1999); Allen v. United States, 
    173 F.3d 533
    , 538 (4th Cir.
    1999).7
    7
    Although the Courts of Appeals for the Fourth and Seventh
    Circuits noted the application of sec. 1.163-8T, Temporary Income
    Tax Regs., 
    52 Fed. Reg. 24999
     (July 2, 1987) (Allen v. United
    States, 
    173 F.3d 533
    , 537 (4th Cir. 1999); Kikalos v.
    (continued...)
    - 12 -
    The Courts of Appeals uniformly relied on the following
    rationale to support their conclusions that section 1.163-
    9T(b)(2)(i)(A), Temporary Income Tax Regs., supra, is not
    invalid: (1) The regulation is not inconsistent with either the
    statute or its legislative history, and (2) the regulation is
    supported by the Staff of the Joint Committee on Taxation,
    General Explanation of the Tax Reform Act of 1986 (J. Comm. Print
    1987), hereinafter referred to as the 1986 Blue Book.    Kikalos v.
    Commissioner, 
    190 F.3d at 798
    ; McDonnell v. United States, 
    180 F.3d at 723
     (adopting the rationale of Redlark v. Commissioner,
    
    141 F.3d at 936
    ); Allen v. United States, 
    173 F.3d at 537-538
    ;
    Redlark v. Commissioner, 
    141 F.3d at 941
    ; Miller v. United
    States, 
    65 F.3d at 690
    .
    Although the judicial landscape surrounding section
    163(h)(2)(A) has changed significantly since our decisions in
    Redlark v. Commissioner, supra, and Kikalos v. Commissioner,
    supra, the legislative landscape has not.   Since section 1.163-
    9T(b)(2)(i)(A), Temporary Income Tax Regs., supra, was published
    in the Federal Register, Congress has not amended section
    163(h)(2)(A) so as to compel a construction of section
    163(h)(2)(A) contrary to the Secretary’s construction as embodied
    7
    (...continued)
    Commissioner, 
    190 F.3d 791
    , 794 (7th Cir. 1999), revg. 
    T.C. Memo. 1998-92
    ), none of the cited Court of Appeals opinions
    specifically discussed the validity of this regulation.
    - 13 -
    in section 1.163-9T(b)(2)(i)(A), Temporary Income Tax Regs.,
    supra.   The Courts of Appeals for the Fourth, Seventh, and Eighth
    Circuits pointed to Congress’s failure to amend section
    163(h)(2)(A) as additional evidence that the regulation is
    reasonable.   Kikalos v. Commissioner, 
    190 F.3d at 799
     (7th Cir.);
    Allen v. United States, 
    173 F.3d at 538
     (4th Cir.); Miller v.
    United States, 
    65 F.3d at 690
     (8th Cir.).
    We have considered the opinions of the Courts of Appeals for
    the Fourth, Sixth, Seventh, Eighth, and Ninth Circuits; those
    opinions are entitled to all due respect.          Lardas v.
    Commissioner, 
    99 T.C. 490
    , 494 (1992).       Appeal in the instant
    case, however, lies to the Court of Appeals for the Fifth Circuit
    which has yet to address the issue presented herein.8
    8
    In Lardas v. Commissioner, 
    99 T.C. 490
    , 494-495 (1992),
    we stated that, in Golsen v. Commissioner, 
    54 T.C. 742
    , 756-757
    (1970), affd. 
    445 F.2d 985
     (10th Cir. 1971), we
    reasoned that, where a reversal would appear
    inevitable, due to the clearly established position of
    the Court of Appeals to which an appeal would lie, our
    obligation as a national court does not require a
    futile and wasteful insistence on our view.
    *    *    *     *      *     *      *
    It should be emphasized that the logic behind the
    Golsen doctrine is not that we lack the authority to
    render a decision inconsistent with any Court of
    Appeals (including the one to which an appeal would
    lie), but that it would be futile and wasteful to do so
    where we would surely be reversed. Accordingly,
    bearing in mind our obligation as a national court, see
    Lawrence v. Commissioner, * * * [
    27 T.C. 713
    , 716-717
    (continued...)
    - 14 -
    Accordingly, we proceed to reconsider our opinions in
    Redlark v. Commissioner, supra, and Kikalos v. Commissioner,
    supra.
    We set forth the pertinent provisions of section 163(h).   We
    then trace the history of the enactment of these provisions, from
    Executive Branch proposals through the legislative process of the
    Tax Reform Act of 1986 (H.R. 3838, the Ways and Means Committee’s
    “clean bill”) and the retroactive amendments enacted in the
    Technical and Miscellaneous Revenue Act of 1988 (TAMRA 1988).   We
    then evaluate the status of the regulations.
    D.   The Statute
    Section 163(a) provides for the deductibility of all
    interest paid or accrued in the taxable year on indebtedness.
    The other subsections of section 163 provide limitations,
    particularized rules, or definitions with regard to the allowance
    8
    (...continued)
    (1957), revd. on other grounds 
    258 F.2d 562
     (9th Cir.
    1958),] we should be careful to apply the Golsen
    doctrine only under circumstances where the holding of
    the Court of Appeals is squarely on point. See Golsen
    v. Commissioner, supra at 757.
    Two District Courts in the Fifth Circuit have concluded that
    section 1.163-9T(b)(2)(i)(A), Temporary Income Tax Regs., 
    52 Fed. Reg. 48409
     (Dec. 22, 1987), is not invalid. Fitzmaurice v.
    United States, 87 AFTR 2d 2001-654, 2001-1 USTC par. 50,198 (S.D.
    Tex. 2001); Davis v. United States, 
    71 F. Supp. 2d 622
     (W.D. Tex.
    1999). Although these opinions are relevant to the instant case,
    they do not control because they are not Court of Appeals
    opinions.

    rule of subsection (a).      As applicable to 1995, the year before
    us, section 163(h) provides, in pertinent part, as follows:
    SEC. 163.   INTEREST.
    *    *       *     *      *   *   *
    (h) Disallowance of Deduction for Personal Interest.--
    (1) In general.–-In the case of a taxpayer other
    than a corporation, no deduction shall be allowed under
    this chapter [chapter 1, relating to normal taxes and
    surtaxes] for personal interest paid or accrued during
    the taxable year.
    (2) Personal interest.–-For purposes of this
    subsection, the term “personal interest” means any
    interest allowable as a deduction under this chapter
    other than–-
    (A) interest paid or accrued on indebtedness
    properly allocable to a trade or business (other
    than the trade or business of performing
    services as an employee),
    (B) any investment interest (within the
    meaning of subsection (d)),
    (C) any interest which is taken into account
    under section 469 in computing income or loss
    from a passive activity of the taxpayer,
    (D) any qualified residence interest within
    the meaning of paragraph (3)), and
    (E) any interest payable under section 6601
    on any unpaid portion of the tax imposed by
    section 2001 for the period during which an
    extension of time for payment of such tax is in
    effect under section 6163 or 6166 or under
    section 6166A (as in effect before its repeal by
    the Economic Recovery Tax Act of 1981).
    Petitioners contend that the interest they paid in respect
    of their 1987 income tax underpayment falls within the terms of
    - 16 -
    section 163(h)(2)(A); they do not contend that their interest
    payment falls within the terms of any of the other subparagraphs
    of section 163(h)(2).   Accordingly, we focus on section
    163(h)(2)(A).
    E.   History of the Legislation (See Appendix infra.)
    In November 1984, the Treasury Department issued a report to
    the President recommending numerous revisions of the tax laws.
    One of the proposals was designed to
    curtail the subsidy implicit in the [then] current law
    deduction of interest on debt to finance large amounts of
    passive, tax-preferred, investment assets (such as corporate
    stock) or extraordinary consumption expenditures (such as
    second homes).
    In May 1985, President Reagan issued a report which included
    a proposal to subject “all interest not incurred in connection
    with a trade or business” to the section 163(d) limitations on
    investment interest.
    The House bill followed the President’s proposal in that it
    would impose a limit on deductibility of “nonbusiness interest”.
    The latter term was defined to exclude “any interest which is
    allowable as a deduction in computing adjusted gross income”.
    The Ways and Means Committee report stated that “Interest expense
    that is paid or incurred in carrying on a trade or business * * *
    is not subject to the interest deduction limitation under the
    bill.”   H. Rept. 99-426 at 298, 1986-3 C.B. (Vol. 2) 1, 298.
    - 17 -
    The Senate amendment separated out the investment interest
    provisions (in a revised sec. 163(d)) and provided a prohibition
    (new sec. 163(h)) on deducting “consumer interest”.     The latter
    term was defined to exclude “interest paid or accrued on
    indebtedness incurred or continued in connection with * * * the
    conduct of a trade or business”.
    The conference committee reached its agreement on August 16,
    1986.   Thirteen days later, the staff of the Joint Committee on
    Taxation published a summary of the agreement, hereinafter
    sometimes referred to as the Joint Committee staff summary.
    Twenty days after that, the conference committee published its
    report.    Thirty-four days after that, the Tax Reform Act of 1986
    was enacted.   The conference committee generally followed the
    Senate’s approach, but changed the language to prohibit any
    deduction for “personal interest”.      For our purposes, “personal
    interest” was defined the same way the Senate bill defined
    “consumer interest”.   The Joint Committee staff summary stated as
    follows:
    Interest on underpayments of tax (other than certain
    deferred estate taxes) is treated as personal interest under
    the provision.
    The conference committee explanation includes the following
    sentence:
    Personal interest also generally includes interest on
    tax deficiencies.
    - 18 -
    On May 4, 1987, the staff of the Joint Committee on Taxation
    published its “Blue Book”, which included the following:
    Personal interest also includes interest on
    underpayments of individual Federal, State or local
    income taxes notwithstanding that all or a portion of
    the income may have arisen in a trade or business.
    * * *
    On June 10, 1987, the chairman and ranking minority member
    of each of the tax-writing committees introduced bills to make
    technical corrections to TRA 1986.     Each bill included the
    following:
    Subparagraph (A) of section 163(h)(2) of the 1986
    Code is amended by striking out “incurred or continued
    in connection with the conduct of” and inserting in
    lieu thereof “properly allocable to”. [Sec. 105(c)(1)
    of H.R. 2636 and S. 1350.]
    Each bill provided that the change was to take effect as
    though it had been included in TRA 1986.     The Ways and Means
    Committee report stated that the change in section 163(h)(2)(A)
    is intended to make it consistent with the language of section
    469, which also had been enacted in TRA 1986.     The House of
    Representatives passed the provision as part of the 1987 Budget
    Reconciliation Act.   The Finance Committee approved the same
    language and described it the same way in its report.
    For reasons unrelated to this provision, the technical
    corrections were dropped from the Omnibus Budget Reconciliation
    Act of 1987, Pub. L. 100-203, 
    101 Stat. 1330
    .     The same
    provisions were then introduced as part of the Technical
    - 19 -
    Correction Act of 1988, with the same effective dates and
    explanations, and ultimately enacted without change by the
    Technical and Miscellaneous Revenue Act of 1988 (TAMRA 1988),
    Pub. L. 100-647, 
    102 Stat. 3342
    .
    The language thus enacted is what we must construe in the
    instant case.
    F.   Analysis of the Statute
    From the foregoing, we draw the following conclusions.
    (1)   Initial Objectives
    Although the movement to enact what became section 163(h)
    may have started with a concern about subsidizing already-tax-
    favored investments and “extraordinary consumption expenditures
    (such as second homes)” (infra Appendix 1.   The Treasury Report),
    the enacted statute is different--narrower in some respects and
    broader in others--from the original announced objectives.
    It is not at all unusual for the Congress to act outside the
    confines of the problem described in the legislative history; the
    Congress has done so in many different areas of the tax law.
    See, e.g., Bartels Trust for Ben. of Univ. v. United States, 
    209 F.3d 147
    , 153-154 (2d Cir. 2000) (relating to charities’
    unrelated trade or business income); Corn Belt Tel. Co. v. United
    States, 
    633 F.2d 114
    , 117-118 (8th Cir. 1980) (relating to the
    definition of “public utility property” for investment credit
    purposes); Warrensburg Board & Paper Corp. v. Commissioner, 77
    - 20 -
    T.C. 1107, 1110-1111 (1981) (relating to subchapter S
    corporations’ “one-shot” elections); Estate of Beal v.
    Commissioner, 
    47 T.C. 269
    , 271-272 (1966) (relating to
    includability of the value of certain annuities in decedents’
    estates).    Where the Congress has chosen to so legislate, the
    courts do not confine the statute to the original problem, but
    rather apply the statute to the net that the Congress has chosen
    to cast.
    In light of the evolution of section 163(h) over the 4 years
    from the Treasury Report to TAMRA 1988, the original objective of
    the proposal cannot be taken as sufficiently explaining the
    meaning of section 163(h)(2)(A).
    (2) The Varying “Handles”; Definition in the Statute
    When the Congress enacts a definition of a term, the
    statutory definition controls over definitions in general
    dictionaries.
    A review of the relevant history of the legislation reveals
    the varying phraseology that the Congress employed in the
    legislative process that culminated in the enactment of section
    163(h)(2).    Five different terms, or “handles”, were used to
    describe the interest, the deductions in respect of which the
    Congress wanted to either limit or disallow: “nonbusiness
    interest”, “nonbusiness consumer interest”, “consumer interest”,
    “personal (consumer) interest”, and “personal interest”.    The
    - 21 -
    Congress also used varying definitions for these terms, e.g.,
    “Interest expense that is paid or incurred in carrying on a trade
    or business” (H. Rept. 99-426 at 298, 1986-3 C.B. (Vol. 2) 1,
    298), “interest paid or accrued on indebtedness incurred or
    continued in connection with–-(i) the conduct of a trade or
    business” (H.R. 3838, sec. 1421 (as passed by the Senate), 132
    Cong. Rec. at S 8921 (June 26, 1986)).
    We make these observations because of the apparent focus on
    the question of whether interest paid in respect of an
    individual’s Federal income tax liability is a “personal
    obligation”.   See Miller v. United States, 
    65 F.3d at 691
    ,
    stating:
    that an individual’s income tax liability, regardless of the
    nature of the income giving rise to the liability, is a
    personal obligation and that, consequently, interest owed by
    such individual because of a failure to pay his tax
    obligation on time necessarily is also a personal
    obligation.
    See also Kikalos v. Commissioner, 
    190 F.3d at 797
     (describing as
    reasonable the view taken by the Secretary therein that interest
    on income tax deficiencies is personal interest because the
    obligation to pay income tax is personal); Allen v. United
    States, 
    173 F.3d at 537
     (stating: “Pursuant to these allocation
    rules, deficiency interest is allocable to the payment of income
    taxes, an expenditure that is purely personal in nature.”);
    Redlark v. Commissioner, 
    141 F.3d at 941
     (agreeing with the
    statement of the Court of Appeals for the Eighth Circuit (Miller)
    - 22 -
    “that personal income tax obligations are always essentially
    personal in nature”).   Despite whatever logical conclusions may
    flow from the Congress’s use of the term “personal interest”, and
    the Congress’s clearly expressed intention to end the deduction
    for indebtedness incurred to finance personal consumption
    expenditures, the instant case does not turn on whether the
    obligation to pay deficiency interest is a “personal obligation”
    or whether the payment of Federal individual income tax is a
    personal consumption expenditure.   Indeed, the obligation to pay
    home mortgage interest is undoubtedly a “personal obligation”,
    yet that type of interest expense is excluded from the definition
    of personal interest.   Sec. 163(h)(2)(D).   Moreover, as we noted
    in Redlark v. Commissioner, 
    106 T.C. at
    42: “To conclude that an
    income tax deficiency is ipso facto a consumption expenditure
    begs the issue.”   Accordingly, the determination whether an item
    of interest is either a “personal obligation” or a “personal
    consumption expenditure” is not the talisman for purposes of
    applying section 163(h).   Rather, the controlling inquiry, as
    framed by the statute itself, is whether the interest in issue is
    “properly allocable to a trade or business”.   Sec. 163(h)(2)(A).
    When, as in the instant case, the Congress undertakes to
    define a term explicitly, “we must follow that definition, even
    if it varies from that term’s ordinary meaning.”    Stenberg v.
    Carhart, 
    530 U.S. 914
    , 942 (2000); Guerrero-Perez v. INS, 242
    - 23 -
    F.3d 727, 736-737 (7th Cir. 2001); see, e.g. Cherin v.
    Commissioner, 
    89 T.C. 986
     (1987).    In other words, we are to
    disregard the connotations of the term, or handle, that the
    Congress adopts and instead focus on the language that the
    Congress actually used to define the term.    This is especially
    true where, as in the instant case, the Congress tells us what
    the term in question “means”.    “As a rule, ‘a definition which
    declares what a term ‘means’ . . . excludes any meaning that is
    not stated.’”     Colautti v. Franklin, 
    439 U.S. 379
    , 392-393 n.10
    (1979).   If, however, the statute in question uses the word
    “includes” rather than “means” to define a term, then there is an
    indication that the definition of the term is exemplary rather
    than exclusive.    Sec. 7701(c); see Winterrowd v. David Freedman
    and Co., Inc., 
    724 F.2d 823
    , 825 (9th Cir. 1984)(citing Highway &
    City Freight Drivers v. Gordon Transports, Inc., 
    576 F.2d 1285
    ,
    1289 (8th Cir. 1978)).
    In Cherin v. Commissioner, 
    89 T.C. at 1000-1001
    , we
    addressed, inter alia, whether the taxpayer’s deficiencies were
    subject to a higher rate of interest under what was then (as to
    interest accruing after Dec. 31, 1984) section 6621(c)9, dealing
    with interest on a substantial underpayment attributable to a
    “tax-motivated transaction”.    We found as facts in Cherin v.
    9
    Sec. 6621(c) later was repealed by sec. 7721(b) of the
    Omnibus Budget Reconciliation Act of 1989, Pub. L. 101-239, 
    103 Stat. 2106
    , 2399.
    - 24 -
    Commissioner, 
    89 T.C. at 987, 988, 991
    , that the taxpayer (1) was
    looking for an investment which would produce significant income
    for his retirement years, (2) reasonably relied on the advice of
    his accountant, financial adviser, and attorney to enter into the
    disputed transaction (a tax shelter involving cattle breeding),
    and (3) contemplated that he would recover the purchase price of
    the two herds in which he invested.    Despite these findings which
    suggested the presence of a profit motive, we concluded that the
    taxpayer’s deficiencies were subject to the higher rate of
    interest under section 6621(c), i.e., that the taxpayer had a
    substantial underpayment attributable to a “tax-motivated
    transaction”.   Cherin v. Commissioner, 
    89 T.C. at 1001
    .    We
    reached our conclusion in Cherin even though the handle the
    Congress chose, “tax-motivated transaction”, suggested the
    importance of the taxpayer’s motives.    Instead of focusing on the
    connotations that logically flowed from that handle, we focused
    on the relevant statutory language, which set forth what the term
    “tax-motivated transaction” “means”.    Sec. 6621(c)(3).
    In the instant case, in restricting the allowance rule of
    section 163(a), the Congress chose the term “personal interest”,
    and the Congress told us what that term “means” in section
    163(h)(2).   As relevant herein, the term “personal interest”
    means “any interest allowable as a deduction under this chapter
    other than–-* * * interest paid or accrued on indebtedness
    - 25 -
    properly allocable to a trade or business (other than the trade
    or business of performing services as an employee)”.   Sec.
    163(h)(2)(A).   Based on this definition of “personal interest”
    that the Congress set forth, the appropriate inquiry in the
    instant case is not whether petitioners’ interest on their 1987
    income tax deficiency is “personal” but whether it is “properly
    allocable to a trade or business”.
    (3) The Pre-TRA 1986 Cases
    In Redlark v. Commissioner, 
    106 T.C. at 34-35
    , we opened our
    discussion of the law as it stood before enactment of TRA 1986 as
    follows:
    The question remains, however, whether the elements giving
    rise to the deficiencies to which the interest herein
    relates are of such a nature as to permit such interest to
    constitute a business expense within the meaning of section
    162(a), and therefore of section 62(a), and, as a result, to
    be characterized as interest “on indebtedness properly
    allocable to a trade or business” within the meaning of
    section 163(h)(2)(A)3 in the event that the temporary
    regulation is not applicable. We think a review of the
    cases decided prior to the enactment of section
    163(h)(2)(A), in respect of the deductibility of interest on
    income tax deficiencies as a business expense, will throw
    light on this question and is therefore a significant
    element in our analysis of the impact of that section on
    petitioners’ claimed interest deduction. It is to that
    review that we first turn our attention.
    ________________
    3
    Sec. 163(h)(2)(A) was amended by sec. 1005(c)(4) of the
    Technical and Miscellaneous Revenue Act of 1988, Pub. L.
    100-647, 
    102 Stat. 3342
    , 3390.
    Sec. 163(h)(2)(A), as originally enacted in 1986,
    provided:
    - 26 -
    (A) interest paid or accrued on indebtedness
    incurred or continued in connection with the conduct of
    a trade or business (other than the trade or business
    of performing services as an employee), [Tax Reform Act
    of 1986, Pub. L. 99-514, sec. 511(b), 
    100 Stat. 2085
    ,
    2246.]
    The amended language, effective for the years in issue,
    was intended to conform the definition of personal interest
    to the language of the related passive loss and investment
    interest limitation provisions, to permit consistent
    application of a standard for allocation of interest. See
    S. Rept. 100-445, at 36 (1988); H. Rept. 100-795, at 35
    (1988). There is no indication that the change in language
    was intended to make any substantive change in the meaning
    of the statutory language.
    We then analyzed three opinions:   Standing v. Commissioner,
    
    28 T.C. 789
     (1957), affd. 
    259 F.2d 450
     (4th Cir. 1958); Polk v.
    Commissioner, 
    31 T.C. 412
     (1958), affd. 
    276 F.2d 601
     (10th Cir.
    1960); Reise v. Commissioner, 
    35 T.C. 571
     (1961), affd. 
    299 F.2d 380
     (7th Cir. 1962).   In each of these opinions we held that the
    interest on a tax underpayment was an ordinary and necessary
    expense “paid or incurred during the taxable year in carrying on
    any trade or business” within the meaning of section 23(a)(1)(A),
    I.R.C. 1939, the predecessor of section 162(a).   In Standing v.
    Commissioner, 
    28 T.C. at 789-795
    , we also held that the interest
    on a tax underpayment was “attributable to” the taxpayer’s trade
    or business within the meaning of section 22(n)(1), I.R.C. 1939,
    the predecessor of section 62(a)(1), hence deductible in arriving
    at adjusted gross income.   In Polk v. Commissioner, 
    31 T.C. at 415
    , we noted that the net operating loss language in section
    122(d)(5), I.R.C. 1939 (the predecessor of sec. 172(d)(4)), was
    - 27 -
    identical to the section 22(n)(1), I.R.C. 1939, language
    construed in Standing and so should have the same meaning as in
    Standing.   In Reise v. Commissioner, 
    35 T.C. at 579-580
    , we noted
    that neither Standing nor Polk discussed our earlier opinion in
    Aaron v. Commissioner, 
    22 T.C. 1370
     (1954), in which we had held
    that interest on a tax underpayment was not attributable to the
    taxpayer’s trade or business within the meaning of section
    122(d)(5), I.R.C. 1939.   In Reise we thereupon overruled Aaron
    and reaffirmed the position we took in Polk that the interest on
    the tax underpayment was attributable to the taxpayer’s trade or
    business.
    In Redlark v. Commissioner, 
    106 T.C. at 37
    , we then
    summarized the effect of the foregoing cases as follows:
    Concededly there is some confusion in the reasoning of
    the decided cases, but the thrust of their bottomline
    conclusions is clear. Exceptions will be accorded to the
    “ordinary and necessary” provision of section 162 only when
    there is explicit legislative indication that such a result
    was intended. Thus, we agree with petitioners that there is
    a consistent body of pre-section 163(h) case law holding
    that, at least under limited circumstances such as were
    involved in Standing v. Commissioner, supra, Polk v.
    Commissioner, supra, and Reise v. Commissioner, supra,
    deficiency interest is a deductible business expense under
    section 162 and therefore under section 62(a)(1). See
    Brennan & Megaard, “Deducting Interest on Noncorporate Trade
    or Business Tax Deficiencies: Uncertainty Exists Under the
    New Temporary Regulations”, 13 Rev. of Taxn. of Individuals
    22 (1989).
    Later in our opinion in Redlark v. Commissioner, 
    106 T.C. at 43
    , we pointed out that
    - 28 -
    we have consistently been reluctant to conclude that
    Congress overruled existing case law when the statutory
    language does not compel such a conclusion and Congress has
    not otherwise expressly indicated that such a result should
    ensue. * * *
    As we noted, supra, in H.R. 3838 as reported by the Ways and
    Means Committee, “nonbusiness interest” was defined to exclude
    “any interest which is allowable as a deduction in computing
    adjusted gross income”.    Proposed amendment to sec. 163(d)(3)(B)
    in sec. 402(a) of H.R. 3838 as reported by the Ways and Means
    Committee.    If that language had been enacted, then our Redlark
    analysis of the statute would properly have led to the conclusion
    that interest on a tax underpayment under the circumstances of
    Redlark and the instant case would continue to be deductible
    under section 162 and that section 163 would not affect that
    deductibility, and that regulations to the contrary would be
    contrary to the statute.
    However, that language was not enacted.     See infra,
    Appendix.    Instead, in TRA 1986 the Congress defined “personal
    interest” to exclude “interest paid or accrued on indebtedness
    incurred or continued in connection with the conduct of a trade
    or business”.    Sec. 163(h)(2)(A) (emphasis added).   In TAMRA 1988
    the Congress changed the language so as to exclude from personal
    interest “interest paid or accrued on indebtedness properly
    allocable to a trade or business.”      Sec. 163(h)(2)(A) (emphasis
    added).   In Standing, Polk, and Reise, the critical statutory
    - 29 -
    language was “in carrying on any trade or business” (sec.
    23(a)(1)(A), I.R.C. 1939) and “attributable to” the taxpayer’s
    trade or business (secs. 22(n)(1) and 122(d)(5), I.R.C. 1939).
    In Redlark v. Commissioner, 
    106 T.C. at 34, 37
    , we did not
    deal with the fact that both the enacted TRA 1986 language (“in
    connection with”) and the enacted TAMRA 1988 language (“properly
    allocable to”) were different from the “in carrying on” and
    “attributable to” language interpreted in the pre-TRA 1986
    opinions.
    Ordinarily, we would expect that a change in statutory
    language indicates a change in meaning.   Russello v. United
    States, 
    464 U.S. 16
    , 23 (1983); cf. Elect. Arts, Inc. v.
    Commissioner, 
    118 T.C. 226
    , 242-243 (2002), and cases there
    cited.10
    10
    This is the general rule not only because of the
    authority of the cited opinions, but also because this is the way
    legislative drafters are instructed to draft statutes. See,
    e.g., Office of the Legislative Counsel U.S. House of
    Representatives, House Legislative Counsel’s Manual on Drafting
    Style, 3 (1995), as follows:
    (4) Use same word over and over.--If you have
    found the right word, don’t be afraid to use it again
    and again. In other words, don’t show your pedantry by
    an ostentatious parade of synonyms. Your English
    teacher may be disappointed, but the courts and others
    who are straining to find your meaning will bless you.
    (5) Avoid utraquistic subterfuges.--Do not use the
    same word in 2 different ways in the same draft (unless
    (continued...)
    - 30 -
    Application of this general rule (if the statutory language
    is different, then it is presumed that the meaning is different)
    to the matter before us leads to the conclusion that section
    163(h)(2)(A) means something different from the statutory
    provisions interpreted in the pre-TRA 1986 opinions.11
    10
    (...continued)
    you give the reader clear warning).
    To the same effect, see Dickerson, The Interpretation and
    Application of Statutes 224 (1975), quoted in Zuanich v.
    Commissioner, 
    77 T.C. 428
    , 443 n.26 (1981), as follows:
    26
    See R. Dickerson, The Interpretation and
    Application of Statutes 224 (1975), as follows:
    Because legal documents are for the most part
    nonemotive, it is presumed that the author’s language
    has been used, not for its artistic or emotional
    effect, but for its ability to convey ideas.
    Accordingly, it is presumed that the author has not
    varied his terminology unless he has changed his
    meaning, and has not changed his meaning unless he has
    varied his terminology; that is, that he has committed
    neither “elegant variation” nor “utraquistic
    subterfuge”. This is the rebuttable presumption of
    formal consistency. [Fn. refs. omitted.]
    See also Hirsch, Drafting Federal Law, sec. 5.2 (3d ed. 1992).
    11
    This presumption is rebuttable. In the TAMRA 1988
    amendments, at every step in the enactment of the change from
    “incurred or continued in connection with the conduct of” to
    “properly allocable to” the Congress stated the intention that
    this was done to effectuate more clearly the original intention
    of TRA 1986 and not to change the meaning of the statute. See
    infra, Appendix. Consistent with these statements of
    congressional intent, the TAMRA 1988 amendments took “effect as
    if included in the provision of” the TRA 1986 to which the TAMRA
    1988 amendments relate. See also Redlark v. Commissioner, 
    106 T.C. at
    34 n.3. However, the parties have not directed our
    attention to, and we have not found, any evidence that either the
    (continued...)
    - 31 -
    We do not intend in the instant case to overrule any of the
    three pre-TRA 1986 opinions--Standing, Polk, or Reise.    The
    statutory terms construed in those cases have been carried
    forward from the Internal Revenue Code of 1939 and now appear in
    section 162(a) (“paid or incurred * * * in carrying on any trade
    or business”), section 62(a)(1) (“attributable to a trade or
    business carried on by the taxpayer”), and section 172(d)(4)
    (“attributable to a taxpayer’s trade or business”).
    However, the result of the Congress’s decisions (1) to use
    different language in section 163(h)(2)(A) and (2) to provide in
    section 163(h)(1) that the disallowance rule overrode everything
    else in chapter 1, is that, as to the issue we cited them for in
    Redlark, the pre-TRA 1986 opinions have become irrelevant to the
    determination of chapter 1 tax liabilities.
    (4)   The Conference Report, The 1986 Blue Book
    In Redlark v. Commissioner, 
    106 T.C. at 42-45
    , we discussed
    the following sentence from the TRA 1986 conference committee
    explanation--
    Personal interest also generally includes interest on
    tax deficiencies
    --with special focus on “generally” and “tax deficiencies”.     We
    noted that “deficiency” is a term of art with a settled
    11
    (...continued)
    enacted TRA 1986 language or the enacted TAMRA 1988 language was
    intended to have the same meaning as the language interpreted in
    the pre-TRA 1986 opinions.
    - 32 -
    definition.   We interpreted the conference committee sentence as
    follows (
    106 T.C. at 44-45
    ):
    In short, we think that when the conference committee
    used the phrase “tax deficiencies”, it was referring to
    amounts due by way of income, estate, and gift taxes. In
    this context, the word “generally” in the conference
    committee report takes on a significant meaning. It signals
    that not all interest relating to income tax, etc.,
    deficiencies are included in “personal interest”. The
    logical explanation for what is excluded by “generally” is
    such interest that constitutes an ordinary and necessary
    business expense and is therefore “allocable to an
    indebtedness of a trade or business” within the meaning of
    the exception clause of section 163(h)(2)(A). To adopt
    respondent’s position would require us to substitute the
    word “always” for “generally” and to expand the
    interpretation of the word “deficiencies” beyond its
    accepted meaning to encompass taxes other than income, etc.,
    taxes in order to account for the use of the word
    “generally”. By way of contrast, our interpretation accepts
    the established meaning of “deficiencies” and gives effect
    to “generally” without modification.
    We then discussed the 1986 Blue Book’s status and concluded
    as follows (
    106 T.C. at 45-46
    ):
    Where there is no corroboration in the actual legislative
    history, we shall not hesitate to disregard the General
    Explanation as far as congressional intent is concerned.7
    See Estate of Wallace v. Commissioner, 
    965 F.2d 1038

     (7th Cir. 1989);8 see also Livingston, supra at 93
    (“The Blue Book is on especially weak ground when it adopts
    anti-taxpayer positions not taken in the committee
    reports.”). Given the clear thrust of the conference
    committee report, the General Explanation is without
    foundation and must fall by the wayside. To conclude other-
    wise would elevate it to a status and accord it a deference
    to which it is simply not entitled.

    of 1986, Pub. L. 99-514, 
    100 Stat. 2085

    22, 1986, during the 99th Congress, whereas the General
    - 33 -
    Explanation was published on May 4, 1987, during the 100th
    Congress. Thus, the General Explanation is not even
    entitled to the respect it might otherwise be accorded if it
    had been prepared for the Congress which enacted sec.
    163(h).
    8
    See also Lawson v. Commissioner, 
    T.C. Memo. 1994-286
    .
    We conclude that there are several difficulties with the
    foregoing analysis in our opinion in Redlark v. Commissioner, 
    106 T.C. at 44-46
    .     For the following reasons, we would not agree
    that the conference committee explanation has a “clear thrust”.
    Firstly, interest ordinarily is imposed on underpayments or
    overpayments, not on deficiencies.       See, e.g., secs. 6601, 6611,
    6621.     There can be an income tax deficiency without an
    underpayment.12    There can be an underpayment without an income
    tax deficiency.13    In describing the amendments made by TRA 1986
    sections 1511 (to sec. 6621, I.R.C. 1986) and 1512 (to sec. 6601,
    I.R.C. 1986), the Joint Statement of Managers portion of the
    conference committee report consistently refers to interest on
    underpayments or overpayments of tax, and it does not refer to
    interest on tax deficiencies.     H. Conf. Rept. 99-841, at II-784
    to II-785 (1986); 1986-3 C.B. (Vol. 4) at 784-785.
    12
    See, e.g., Lundy v. Commissioner, 
    T.C. Memo. 1993-278
    ,
    revd. 
    45 F.3d 856
     (4th Cir. 1995), revd. 
    516 U.S. 235
     (1996), in
    which the parties agreed that the taxpayer had a $778 deficiency
    even though the taxpayer’s withheld (and not refunded) income
    taxes exceeded his total tax liability.
    13
    E.g., when a correct tax return is filed, but the
    payments are less than the correctly stated liabilities.
    - 34 -
    Thus, it is not clear whether the term “deficiency”, to
    which we attributed such significance in Redlark v. Commissioner,
    
    106 T.C. at 44-45
    , is merely an inadvertence in one portion of
    the conference committee report.
    Secondly, the word “generally” may merely serve the function
    of alerting the reader that there is a category of interest on
    tax underpayments that does not fit into the definition of
    “personal interest”--to wit, the interest described in
    subparagraph (E) of section 163(h)(2), as follows:
    (E) any interest payable under section 6601 on any
    unpaid portion of the tax imposed by section 2001 for the
    period during which an extension of time for payment of such
    tax is in effect under section 6163 or 6166.[14] [Joint
    Committee staff summary at 18.]
    Thirdly, the Joint Committee staff summary, published 20
    days before the Conference Report, described the provision as
    follows:
    Interest on underpayments of tax (other than certain
    deferred estate taxes) is treated as personal interest
    under the provision.
    Apart from the use of “underpayments” rather than “deficiencies”,
    the Joint Committee staff summary appears to be completely
    consistent with the conference committee sentence on which we
    focused in Redlark v. Commissioner, 
    106 T.C. at
    44-45--and quite
    inconsistent with the conclusion we drew in Redlark.
    14
    The reference to sec. 6166 later was stricken by sec.
    503(b)(2)(B) of the Taxpayer Relief Act of 1997, Pub. L. 105-34,
    
    111 Stat. 788
    .
    - 35 -
    Fourthly, even if we were to agree that the use of
    “deficiencies” in the conference committee sentence is
    significant, the only significance stated in Redlark v.
    Commissioner, 
    106 T.C. at 44
    , is that it refers to “amounts due
    by way of income, estate, and gift taxes.”15   As we noted supra
    in Secondly and Thirdly, the exclusion provided by subparagraph
    (E) of section 163(h)(2) is an exclusion of interest on estate
    tax in certain circumstances.    This is a far simpler explanation
    of the conference committee sentence than the labored explanation
    in Redlark; it provides consistency of meaning among the various
    documents in the history of the legislation; and it refutes the
    conclusion in Redlark v. Commissioner, 
    106 T.C. at 46
    , that the
    conference committee sentence has a “clear thrust” that requires
    us to reject the TRA 1986 Blue Book and to invalidate Treasury
    Regulations.   Of course, if a Blue Book were to conflict with
    enacted language or controlling legislative history, then the
    statutory language or the controlling legislative history would
    prevail.   In our view, the conference committee report is not
    clear regarding which category of interest was intended to be
    excepted from “personal interest”; i.e., which category made it
    15
    Beginning with the Tax Reform Act of 1969, Pub. L. 91-
    172, 
    83 Stat. 487
    , the Congress began to bring a series of
    regulatory excise taxes into the definition of “deficiency” in
    sec. 6211. At the time TRA 1986 was enacted, the definition
    included the taxes imposed by chs. 41 through 45, in addition to
    the income, estate, and gift taxes imposed by subtits. A and B.
    - 36 -
    necessary to qualify the statement about personal interest with
    “generally”.   The Blue Book identifies another possible category
    besides interest on a deficiency arising in the case of a sole
    proprietorship, which contributes to the conclusion that the
    controlling legislative history’s meaning is unclear.
    (5) Conclusions From the Statute and the History of the
    Legislation
    The relevant statutory language is not the term “personal
    interest”, but the definitional term in subparagraph (A) of
    section 163(h)(2), in the context of the remaining elements of
    the definition.   That definitional term differs from the
    statutory language construed in the three pre-TRA 1986 opinions
    relied on in Redlark, and so the meaning of that definitional
    term presumably is different from the meanings of the statutory
    language construed in those three opinions.
    The relevant statutory language does not provide a clear
    answer to the dispute before us in the instant case.
    The history of the legislation clearly shows an evolution in
    the Congress’s thinking during the legislative process; it
    provides some support for the validity of the Treasury
    regulations, but that support is rebuttable.   Apart from the
    analysis in Redlark, that history does not provide support for
    the conclusion that the Treasury regulations are invalid.
    - 37 -
    In this relatively inconclusive setting, we proceed to
    examine the Treasury regulations.
    G.   The Regulations
    In the instant case, we consider the validity of the
    following regulations: (1) section 1.163-8T(c) and (c)(3)(ii),
    Temporary Income Tax Regs.,16 
    52 Fed. Reg. 24999
     (July 2, 1987),
    16
    Sec. 1.163-8T(c)(1) and (c)(3)(ii), Temporary Income Tax
    Regs., supra, provides in pertinent part as follows:
    Sec. 1.163-8T Allocation of interest expense among
    expenditures (temporary).
    (a) In General--(1) Application. This section
    prescribes rules for allocating interest expense for
    purposes of applying sections 469 (the “passive loss
    limitation”) and 163(d) and (h) (the “nonbusiness interest
    limitations”).
    *      *   *   *    *    *    *
    (c) Allocation of debt and interest expense–-(1)
    Allocation in accordance with use of proceeds. Debt is
    allocated to expenditures in accordance with the use of the
    debt proceeds and, * * *. * * * debt proceeds and related
    interest expense are allocated solely by reference to the
    use of such proceeds, and the allocation is not affected by
    the use of an interest in any property to secure the
    repayment of such debt or interest. * * *
    *      *   *   *    *    *    *
    (3) Allocation of debt; proceeds not disbursed to
    borrower--* * *
    *      *   *   *    *    *    *
    (ii) Debt assumptions not involving cash disbursements.
    If a taxpayer incurs or assumes a debt in consideration for
    the sale or use of property, for services, or for any other
    purpose, or takes property subject to a debt, and no debt
    (continued...)
    - 38 -
    and (2) section 1.163-9T(b)(2)(i)(A), Temporary Income Tax
    Regs.,17 
    52 Fed. Reg. 48409
     (Dec. 22, 1987).    See Redlark v.
    16
    (...continued)
    proceeds are disbursed to the taxpayer, the debt is treated
    for purposes of this section as if the taxpayer used an
    amount of the debt proceeds equal to the balance of the debt
    outstanding at such time to make an expenditure for such
    property, services, or other purpose.
    17
    Sec. 1.163-9T(b)(2)(i)(A), Temporary Income Tax Regs.,
    supra, provides as follows:
    Sec. 1.163-9T Personal interest (temporary).
    *    *    *     *      *   *    *
    (b) Personal interest–-
    *    *    *     *      *   *    *
    (2) Interest relating to taxes–-(i) In general. Except
    as provided in paragraph (b)(2)(iii) of this section,
    personal interest includes interest–-
    (A) Paid on underpayments of individual Federal, State
    or local income taxes and on indebtedness used to pay such
    taxes (within the meaning of sec. 1.168-8T), regardless of
    the source of the income generating the tax liability.
    *    *    *     *      *   *    *
    (ii) Example.
    A, an individual, owns stock of an S corporation. On
    its return for 1987, the corporation underreports its
    taxable income. Consequently, A underreports A’s share of
    that income on A’s tax return. In 1989, A pays the
    resulting deficiency plus interest to the Internal Revenue
    Service. The interest paid by A in 1989 on the tax
    deficiency is personal interest, notwithstanding the fact
    that the additional tax liability may have arisen out of
    income from a trade or business. The result would be the
    same if A’s business had been operated as a sole
    proprietorship.

    Commissioner, 
    106 T.C. at 40-42
    ; see also supra note 6 (regarding
    the continuing vitality of these temporary regulations, notwith-
    standing section 7805(e)(2)).
    (1) Standards for Judging Validity of Regulations
    Section 1.163-8T, Temporary Income Tax Regs., supra, was
    promulgated under the authority of sections 469(l)(4)18 and 7805,
    the basic regulation-prescribing authority for the Treasury
    Department.   T.D. 8145, 1987-
    2 C.B. 47
    , 50.   In the relevant
    Notice of Proposed Rulemaking, the Commissioner concluded that
    section 1.163-8T, Temporary Income Tax Regs., supra, is an
    interpretative regulation.   
    52 Fed. Reg. 25036
     (July 2, 1987);
    1987-
    2 C.B. 1053
    .   For purposes of the instant case, we agree
    with the Commissioner’s conclusion and treat section 1.163-8T,
    Temporary Income Tax Regs., supra, as an interpretative
    regulation because the legislative delegation to the Secretary to
    17
    (...continued)
    Given the interaction between secs. 1.163-8T and 1.163-9T,
    Temporary Income Tax Regs., supra, and the fact that there is no
    sec. 1.168-8T, Temporary Income Tax Regs., it appears that the
    reference to sec. 1.168-8T, Temporary Income Tax Regs., supra, in
    sec. 1.163-9T(b)(2)(i)(A), supra, should be to sec. 1.163-8T,
    Temporary Income Tax Regs., supra, instead. See sec. 1.163-
    9T(b)(3), Temporary Income Tax Regs., supra (cross-referencing
    sec. 1.163-8T, Temporary Income Tax Regs., supra, for rules
    determining the allocation of interest expense to various
    activities).
    18
    Treasury Decision 8145 refers to sec. 469(k)(4). T.D.
    8145, 1987-
    2 C.B. 47
    , 50. That provision was redesignated as
    sec. 469(l)(4). See Appendix note 1. For convenience, we refer
    to this provision as sec. 469(l)(4).
    - 40 -
    prescribe regulations relates to section 469 only.    Sec.
    469(l)(4); Hughes Intl. Sales Corp. v. Commissioner, 
    100 T.C. 293
    , 303-304 (1993).
    Section 1.163-9T, Temporary Income Tax Regs., supra, was
    promulgated under section 7805.    T.D. 8168, 1988-
    1 C.B. 80
    , 83.
    In the relevant Notice of Proposed Rulemaking, 1988-
    1 C.B. 926
    ,
    927, the Commissioner concluded that section 1.163-9T, Temporary
    Income Tax Regs., supra, is an interpretative regulation.     For
    purposes of the instant case, we agree with the Commissioner’s
    conclusion and treat section 1.163-9T, Temporary Income Tax
    Regs., supra, as an interpretative regulation.
    Although interpretative regulations are entitled to
    considerable weight, they are accorded less deference than
    legislative regulations, which are issued under a specific grant
    of authority to address a matter raised by the relevant statute.
    Chevron U.S.A. v. Natural Res. Def. Council, 
    467 U.S. 837
    , 843-
    844 (1984); United States v. Vogel Fertilizer Co., 
    455 U.S. 16
    ,
    24 (1982).   Temporary regulations are accorded the same weight as
    final regulations.     Peterson Marital Trust v. Commissioner, 
    102 T.C. 790
    , 797 (1994), affd. 
    78 F.3d 795
     (2d Cir. 1996).
    An interpretative regulation is to be upheld if it
    “‘implement[s] the congressional mandate in some reasonable
    manner.’” United States v. Vogel Fertilizer Co., 
    455 U.S. at 24
    (quoting United States v. Correll, 
    389 U.S. 299
    , 307 (1967)).       In
    - 41 -
    making this determination, we employ the following analysis set
    forth by the Supreme Court:
    Under the formulation now familiar, when we confront an
    expert administrator’s statutory exposition, we inquire
    first whether “the intent of Congress is clear” as to
    “the precise question at issue.” Chevron U.S.A. Inc.
    v. Natural Resources Defense Council, Inc., 
    467 U.S. 837
    , 842 (1984). If so, “that is the end of the
    matter.” 
    Ibid.
     But “if the statute is silent or
    ambiguous with respect to the specific issue, the
    question for the court is whether the agency’s answer
    is based on a permissible construction of the statute.”
    
    Id., at 843
    . If the administrator’s reading fills a
    gap or defines a term in a way that is reasonable in
    light of the legislature’s revealed design, we give the
    administrator’s judgment “controlling weight.” 
    Id., at 844
    . [NationsBank of N.C., N.A. v. Variable Annuity
    Life Ins. Co., 
    513 U.S. 251
    , 257 (1995).]
    Accordingly, we must first consider the statute and determine
    whether section 163(h)(2)(A) is silent or ambiguous with respect
    to the issue before us.   If we conclude that it is, then we must
    consider the Secretary’s regulatory interpretation of section
    163(h)(2)(A) on this issue and determine whether that
    interpretation represents a permissible construction of the
    statute.   We address each of these considerations in turn.
    (2) Silence or Ambiguity
    As set forth supra, the relevant inquiry in the instant case
    is whether petitioners’ interest on their 1987 income tax
    underpayment is “properly allocable to a trade or business”.
    We have concluded (supra F (5) Conclusions From the Statute
    and the History of the Legislation) that the statutory text does
    not on its face provide the answer to the question before us.   By
    - 42 -
    choosing to use a definition different from the statutory phrases
    we had earlier construed, the Congress apparently intended a
    meaning different from the meaning of those earlier statutory
    phrases, but the statutory text does not reveal specifically what
    that difference is.   The history of the legislation provides some
    support for a specific answer, but that support is rebuttable.
    Every Court of Appeals which has addressed the issue
    presented herein has reached the same conclusion that the statute
    is silent or ambiguous.   Kikalos v. Commissioner, 
    190 F.3d at 797
    ; McDonnell v. United States, 
    180 F.3d at 723
    ; Allen v. United
    States, 
    173 F.3d at 536
     (describing the term “properly allocable”
    as “manifestly ambiguous”); Redlark v. Commissioner, 
    141 F.3d at 940
     (describing as “untenable” the “assertion that the words,
    ‘properly allocable’, unambiguously specify that interest on
    business-related personal income tax deficiencies should be
    deductible”); Miller v. United States, 
    65 F.3d at 690
     (describing
    Congress’s failure to “define what constitutes business interest”
    as “an implicit legislative delegation of authority to the
    Commissioner to clarify whether income tax deficiency interest is
    ‘properly allocable to a trade or business.’”); see also Tedori
    v. United States, 
    211 F.3d 488
    , 493 (9th Cir. 2000) (stating
    “‘the common and ordinary meaning’ of the statutory phrase
    ‘properly allocable to a trade or business’ is not at all
    plain”).
    - 43 -
    We conclude that section 163(h)(2)(A) is silent or
    ambiguous.    We now proceed to the second prong of our analysis;
    i.e., whether the regulations in issue are based on permissible
    constructions of section 163(h)(2)(A).
    (3) Permissible Construction
    To be valid, a regulation need not be the only, or even the
    best, construction of the statute it purports to implement.
    Atlantic Mut. Ins. Co. v. Commissioner, 
    523 U.S. 382
    , 389 (1998);
    see Romann v. Commissioner, 
    111 T.C. 273
    , 282 (1998).      The
    Supreme Court has stated that a reviewing court--
    need not conclude that the agency construction was the
    only one it permissibly could have adopted to uphold
    the construction, or even the reading the court would
    have reached if the question initially had arisen in a
    judicial proceeding. [Chevron U.S.A. v. Natural Res.
    Def. Council, 
    467 U.S. at
    843 n.11.]
    Rather, the reviewing court need only conclude that the
    regulation is reasonable.      Cottage Savings Assn. v. Commissioner,
    
    499 U.S. 554
    , 560-561 (1991)(citing National Muffler Dealers
    Assn. v. United States, 
    440 U.S. 472
    , 476-477 (1979)).      A
    regulation is reasonable if it harmonizes with the plain
    language, origin, and purpose of the statute it purports to
    implement.     United States v. Vogel Fertilizer Co., 
    455 U.S. at 25-26
    ; National Muffler Dealers Assn. v. United States, 
    440 U.S. at 477
    .
    (a)   Section 1.163-8T, Temporary Income Tax Regs., 
    52 Fed. Reg. 24999
     (July 2, 1987).
    Section 1.163-8T, Temporary Income Tax Regs., supra,
    provides the rules for the allocation of interest expense for
    - 44 -
    purposes of sections 163(d), 163(h), and 469.   Sec. 1.163-
    8T(a)(1), Temporary Income Tax Regs., supra.    Although the
    Congress did not itself devise the allocation rules, the Congress
    clearly stated how it expected the allocation rules to operate.
    The Joint Statement of Managers portion of the conference
    committee report dealing with section 469 states, in pertinent
    part, as follows (H. Conf. Rept. 99-841 at II-146 (1986), 1986-3
    C.B. (Vol. 4) at 146):
    Expenses allocable to portfolio income.--The conference
    agreement provides that portfolio income is reduced by the
    deductible expenses (other than interest) that are clearly
    and directly allocable to such income. Properly allocable
    interest expense also reduces portfolio income. Such
    deductions accordingly are not treated as attributable to a
    passive activity.
    The conferees anticipate that the Treasury will issue
    regulations setting forth standards for appropriate
    allocation of expenses and interest under the passive loss
    rule. The conferees anticipate that regulations providing
    guidance to taxpayers with respect to interest allocation
    will be issued by December 31, 1986. These regulations
    should be consistent with the purpose of the passive loss
    rules to prevent sheltering of income from personal services
    and portfolio income with passive losses. Moreover, the
    regulations should attempt to avoid inconsistent allocation
    of interest deductions under different Code provisions.4
    In the case of entities, a proper method of
    allocation may include, for example, allocation of
    interest to portfolio income on the basis of assets,
    although there may be situations in which tracing is
    appropriate because of the integrated nature of the
    transactions involved. Because of the difficulty of
    recordkeeping that would be required were interest
    expense of individuals allocated rather than traced, it
    is anticipated that, in the case of individuals,
    interest expense generally will be traced to the asset
    or activity which is purchased or carried by incurring
    or continuing the underlying indebtedness.
    - 45 -
    ________________
    4
    For example, an interest deduction that is disallowed
    under section 265 or 291 should not be allowed, capitalized,
    or suspended under another provision.
    The Congress’s suggestion, however, specifically related to
    the allocation rules for section 469 only; the Joint Statement of
    Managers portion of the conference committee report does not
    provide a similar prescription for allocating interest expense
    for purposes of subsections (d) and (h) of section 163.   In TAMRA
    1988, the Congress amended subsections (d) and (h) of section 163
    to conform the relevant language thereof to the relevant language
    of section 469 in order to achieve “consistent application of a
    standard for allocation of interest” among the “related
    provisions” of sections 163(d), 163(h), and 469.   By conforming
    the language of subsections (d) and (h) to section 163 to the
    relevant language of section 469, the Congress gave a clear
    indication that the tracing regime it contemplated for purposes
    of section 469 is the allocation method that it also intended for
    subsections (d) and (h) of section 163.   See Appendix pp. 73-74.
    An examination of section 1.163-8T, Temporary Income Tax
    Regs., supra, shows that the Secretary heeded the Congress’s
    suggestion.   Section 1.163-8T, Temporary Income Tax Regs., supra,
    imposes the very tracing regime that the Congress contemplated.
    Sec. 1.163-8T(a)(3), Temporary Income Tax Regs., supra.
    In sum, the Congress suggested the means by which to
    allocate interest expense for purposes of section 469; the
    - 46 -
    Secretary followed that suggestion; and the Congress later
    amended the relevant language of sections 163(d) and 163(h) to
    conform to the relevant language of section 469.    In light of
    these circumstances, we conclude that the tracing regime that
    section 1.163-8T, Temporary Income Tax Regs., supra, imposes is a
    permissible construction of section 163(h)(2)(A).
    In addition to providing rules for the allocation of
    interest expense, section 1.163-8T, Temporary Income Tax Regs.,
    supra, also provides rules for the treatment of interest expense
    so allocated.   Section 1.163-8T(a)(4)(A), Temporary Income Tax
    Regs., supra, provides that “Interest expense allocated to a
    trade or business expenditure (as defined in paragraph (b)(7) of
    this section) is taken into account under section 163(h)(2)(A)”.
    Section 163(h)(2)(A) is the provision that petitioners contend
    applies to their payment of interest on their 1987 Federal
    individual income tax deficiency.   Section 1.163-8T(b)(7),
    Temporary Income Tax Regs., supra, defines the term “trade or
    business expenditure” to mean “an expenditure (other than a
    passive activity expenditure or an investment expenditure) in
    connection with the conduct of any trade or business other than
    the trade or business of performing services as an employee.”     If
    an expenditure “is not a trade or business expenditure, a passive
    activity expenditure, or an investment expenditure”, then section
    1.163-8T(a)(4)(D), Temporary Income Tax Regs., supra, treats the
    - 47 -
    expenditure as personal interest for purposes of section 163(h).
    Sec. 1.163-8T(b)(5), Temporary Income Tax Regs., supra.
    As previously noted, section 1.163-8T(c)(3)(ii), Temporary
    Income Tax Regs., 
    52 Fed. Reg. 25001
     (July 2, 1987), allocates
    petitioners’ payment of interest on their 1987 Federal individual
    income tax underpayment to the satisfaction thereof.     The
    treatment of petitioners’ interest payment thus depends on
    whether the payment of one’s Federal individual income tax
    liability is an expenditure that is “in connection with the
    conduct of any trade or business”.     While reasonable arguments
    may lie on either side of this issue, the Secretary has
    undertaken to resolve it in promulgating section 1.163-9T(b)(2),
    Temporary Income Tax Regs., 
    52 Fed. Reg. 48409
     (Dec. 22, 1987),
    and it is our charge not to resolve that issue ourselves, but
    rather to determine “whether there is any reasonable basis for
    the resolution embodied in the Commissioner's Regulation.”
    Fulman v. United States, 
    434 U.S. 528
    , 536 (1978); see also CSX
    Corp. v. Commissioner, 
    89 T.C. 134
    , 153 (1987).     We now turn our
    attention to that task.
    (b)   Section 1.163-9T(b)(2)(i)(A), Temporary Income Tax
    Regs., 
    52 Fed. Reg. 48409
     (Dec. 22, 1987)
    As applied to the instant case, section 1.163-
    9T(b)(2)(i)(A), Temporary Income Tax Regs., supra, treats
    petitioners’ payment of interest on their 1987 income tax
    underpayment as nondeductible “personal interest”.     The text of
    - 48 -
    section 163(h)(2)(A) does not compel this result.   The relevant
    legislative history, however, lends some support to this
    interpretation of the statute.
    The Joint Committee staff summary, which we did not consider
    in Redlark v. Commissioner, supra, provides, in pertinent part,
    as follows: “Interest on underpayments of tax (other than certain
    deferred estate taxes) is treated as personal interest under the
    provision [sec. 163(h)].”   Joint Committee staff summary at 18.
    Under this view, interest on underpayments of “certain deferred
    estate taxes” is the only type of interest on underpayments of
    tax that is excluded from the definition of personal interest.
    This view supports section 1.163-9T(b)(2)(i)(A), Temporary Income
    Tax Regs., supra, which includes interest paid on underpayments
    of Federal income taxes within the definition of personal
    interest.
    We acknowledge that the Joint Committee staff summary is not
    the official legislative document for the conference committee’s
    decisions about TRA 1986; that distinction is accorded the
    conference committee report.   Joint Committee staff summary at
    XIII.   Further, by definition, the Joint Committee staff summary
    may not be a complete or thorough statement of the conference
    decisions; summaries are designed to cover concisely the main
    points of the summarized topic, and they may lack specific
    detail.   However, the Joint Committee staff summary was provided
    - 49 -
    to the Members of the House and Senate for their reference before
    Congress enacted TRA 1986, and consequently it is part of the
    history of the legislation.    See, e.g., Newborn v. Commissioner,
    
    94 T.C. 610
    , 620, 623 (1990).    Thus, before the enactment of TRA
    1986, the Members of Congress had before them an interpretation
    of section 163(h) that included within the definition of
    “personal interest” interest on underpayments of income tax.
    Although not as clearly expressed as in the Joint Committee
    staff summary, the relevant portions of the Joint Statement of
    Managers portion of the conference committee report may be read
    to echo the views expressed in the Joint Committee staff summary.
    The relevant portions of the Joint Statement of Managers portion
    of the conference committee report provide that “Personal
    interest also generally includes interest on tax deficiencies”
    and that “personal interest does not include * * * interest
    payable on estate tax deferred under sec. 6163 or 6166.”    H.
    Conf. Rept. 99-841, at II-154, supra, 1986-3 C.B. (Vol. 4) at
    154.    These portions of the Joint Statement of Managers Portion
    of the conference committee report may be read to support a view
    that interest on all tax underpayments other than interest in
    respect of estate tax deferred under either section 6163 or 6166
    is to be treated as personal interest.
    Although the Joint Statement of Managers portion of the
    conference committee report does not speak as clearly to the
    - 50 -
    issue before us as the Joint Committee staff summary does, one
    may reasonably view these two pieces of legislative history as
    being consistent with one another.     At the very least, in light
    of the Joint Committee staff summary, and the validation of
    section 1.163-9T(b)(2)(i)(A), Temporary Income Tax Regs., supra,
    by five Courts of Appeals, an interpretation of the Joint
    Statement of Managers portion of the conference committee report
    that includes income tax deficiencies within the definition of
    personal interest cannot be said to be clearly inconsistent with
    section 163(h)(2)(A).   We so conclude.
    We reached the opposite conclusion in Redlark v.
    Commissioner, 
    106 T.C. at 46
    , and we used that conclusion as the
    basis for disregarding the 1986 Blue Book.    The 1986 Blue Book
    provides, in pertinent part, as follows:
    Personal interest also includes interest on
    underpayments of individual Federal, State or local
    income taxes notwithstanding that all or a portion of
    the income may have arisen in a trade or business,
    because such taxes are not considered derived from the
    conduct of a trade or business.60 However, personal
    interest does not include interest payable on estate
    tax deferred under sections 6163 or 6166.
    ________________
    60
    Personal interest does not include interest on
    taxes, other than income taxes, that are incurred in
    connection with a trade or business. (For the rule
    that taxes on net income are not attributable to a
    trade or business, see Treas. Reg. sec. 1.62-1(d),
    relating to nondeductibility of State income taxes in
    computing adjusted gross income.) * * * [1986 Blue
    Book at 266.]
    - 51 -
    The above quoted portion of the 1986 Blue Book clearly supports
    section 1.163-9T(b)(2)(i)(A), Temporary Income Tax Regs., supra.
    In Redlark v. Commissioner, supra, we did not assign any
    weight to the 1986 Blue Book because we concluded that it
    conflicted with the Joint Statement of Managers and with what we
    there believed to be relevant prior caselaw.    As we have
    explained, supra, that caselaw construed statutory language
    different from what we deal with herein.    Also, the 1986 Blue
    Book is consistent with the Joint Committee staff summary, and we
    believe that the Joint Committee staff summary is consistent with
    the Joint Statement of Managers.
    Whether one views the legislative history of section 163(h)
    as inconclusive or as consistent with section 1.163-
    9T(b)(2)(i)(A), Temporary Income Tax Regs., supra, the 1986 Blue
    Book warrants consideration.   See FPC v. Memphis Light, Gas &
    Water Div., 
    411 U.S. 458
    , 471-472 (1973); Bank of Clearwater v.
    United States, 
    7 Cl. Ct. 289
    , 294 (1985).    Consideration of the
    1986 Blue Book (where, as here, it does not conflict with the
    enacted statutory language and does not conflict with what we
    have referred to as the conference committee sentence (supra
    F.(4) Thirdly)), in combination with the Joint Committee staff
    summary and the relevant portion of the Joint Statement of
    Managers portion of the conference committee report points toward
    a conclusion that section 1.163-9T(b)(2)(i)(A), Temporary Income
    - 52 -
    Tax Regs., supra, is a permissible construction of section
    163(h)(2)(A).   We so conclude.
    We have concluded that section 163(h)(2)(A) is silent or
    ambiguous.   We have also concluded that section 1.163-8T,
    Temporary Income Tax Regs., supra, and section 1.163-
    9T(b)(2)(i)(A), Temporary Income Tax Regs., supra, are
    permissible constructions of section 163(h)(2)(A).     Accordingly,
    we also conclude that both regulations are not invalid.     To the
    extent that Redlark v. Commissioner, supra, is inconsistent
    herewith, we no longer follow that opinion.
    H.   Petitioners’ Alternative Contention
    Alternatively, petitioners contend that section 1.163-
    9T(b)(2)(i)(A), Temporary Income Tax Regs., supra, does not
    control because it relates to section 163(h)(2)(A) as enacted by
    TRA 1986, not to section 163(h)(2)(A) as amended by TAMRA 1988;
    section 163(h)(2)(A) as amended by TAMRA 1988 is the provision
    which applies in the instant case.     Respondent contends that
    section 1.163-9T(b)(2)(i)(A), Temporary Income Tax Regs., supra,
    controls because the amendment to section 163(h)(2)(A) was not
    intended to make any substantive change to the statute.     We agree
    with respondent.
    As we stated in Redlark v. Commissioner, 
    106 T.C. at
    34 n.3:
    The amended language, effective for the years in
    issue, was intended to conform the definition of
    personal interest to the language of the related
    passive loss and investment interest limitation
    - 53 -
    provisions, to permit consistent application of a
    standard for allocation of interest. See S. Rept. 100-
    445, at 36 (1988); H. Rept. 100-795, at 35 (1988).
    There is no indication that the change in language was
    intended to make any substantive change in the meaning
    of the statutory language.
    We hold for respondent on this issue.
    Decision will be entered
    for respondent.

    Appendix
    History of the Legislation
    (1)   The Treasury Report
    In November 1984, the Treasury Department issued a report to
    the President entitled “Tax Reform for Fairness, Simplicity, and
    Economic Growth”, hereinafter sometimes referred to as the
    Treasury Report.     In the Treasury Report, the Treasury Department
    explained that under then-governing law, all interest expense was
    “deductible, either as a business or investment expense or as an
    itemized deduction.”    The Treasury Report at 83.   To
    curtail the subsidy implicit in the [then] current law
    deduction for interest on debt to finance large amounts of
    passive, tax-preferred, investment assets (such as corporate
    stock) or extraordinary consumption expenditures (such as
    second homes).
    the Treasury Department proposed to limit the deductions
    individuals could claim for interest expense “to the sum of
    mortgage interest on the principal residence of the taxpayer,
    passive investment income (including interest income), and $5,000
    per return.”   
    Id.
    (2)   The President’s Proposals
    In May 1985, President Reagan issued a report entitled “The
    President’s Tax Proposals to the Congress for Fairness, Growth,
    and Simplicity”, hereinafter sometimes referred to as the
    President’s Proposals.    Chapter 13.01 of the President’s
    Proposals addressed interest deductions and proposed to subject,
    - 55 -
    inter alia, “all interest not incurred in connection with a trade
    or business” to the then governing limitation on the deduction of
    investment interest under section 163(d).    The President’s
    Proposals at 323.    Underlying this proposal was a concern that
    “consumer interest”, defined as “i.e., interest incurred to
    acquire personal assets, such as a car or vacation home”,
    undermined the then existing “limitations on investment interest
    and interest incurred to acquire tax-exempt bonds.”     
    Id.
     at 322-
    323.
    (3) The House Bill
    Subsection (d) of section 163 in then-current law was
    entitled “Limitation on Interest on Investment Indebtedness.”      In
    section 402(a) of H.R. 3838, the Ways and Means Committee
    proposed to deal with several concerns by revising subsection
    (d), which would be reentitled “Limitation on Nonbusiness
    Interest.”    The bill combined the different concerns into a
    single overall test, as appears from proposed new paragraphs (1)
    and (3) of subsection (d), as follows:
    SEC. 402.   LIMITATION ON DEDUCTION FOR NONBUSINESS INTEREST.
    (a) General Rule.--Subsection (d) of section 163
    (relating to limitation on interest on investment
    indebtedness) is amended to read as follows:
    “(d) Limitation on Nonbusiness Interest.--
    “(1) In general.--In the case of a taxpayer other
    than a corporation, the amount allowed as a deduction
    under this chapter for nonbusiness interest for any
    taxable year shall not exceed the sum of--
    - 56 -
    “(A) $10,000 ($20,000, in the case of a
    joint return), plus
    “(B) the net investment income for the
    taxable year.
    “In the case of a trust, the amount specified in
    subparagraph (A) shall be zero.
    *    *       *     *      *   *   *
    “(3) Nonbusiness interest.--For purposes of this
    subsection, the term ‘nonbusiness interest’ means any
    interest allowable as a deduction under this chapter
    (determined without regard to paragraph (1)); except
    that such term shall not include--
    “(A) any qualified residence interest, and
    “(B) any interest which is allowable as a
    deduction in computing adjusted gross income
    and which is not attributable to a limited
    business interest.
    For purposes of the preceding sentence, the term
    ‘interest’ includes any amount allowable as a deduction
    in connection with personal property used in a short
    sale.[”]
    The term “limited business interest” is defined (in subsec.
    (d)(6)) in terms of lack of active participation in the business;
    it apparently would not apply to Edward’s law practice.   As to
    the prior law’s deductibility of interest in computing adjusted
    gross income, see infra F. (3) Pre-TRA 1986 Cases.
    The Ways and Means Committee Report to accompany H.R. 3838,

    Explanation of Provision
    In general
    The bill expands the scope of the interest
    limitation, and alters the calculation of the amount of
    the limitation. Under the bill, all nonbusiness
    interest is subject to the limitation on deductibility,
    including consumer interest and certain interest that
    is not treated as investment interest subject to
    limitation under present law. Nonbusiness interest
    subject to the limitation under the bill does not
    include interest on debt secured by the taxpayer’s
    principal residence (to the extent of its fair market
    value), and interest on debt secured by a second
    residence of the taxpayer (to the extent of its fair
    market value). Interest expense that is paid or
    incurred in carrying on a trade or business (except for
    interest attributable to certain limited business
    interests not involving low-income housing), is not
    subject to the interest deduction limitation under the
    bill. [Id. at 298.]
    *   *     *      *      *      *   *
    - 58 -
    Interest subject to the limitation
    Under the bill, interest subject to the limitation
    is all interest on debt not incurred in connection with
    the taxpayer’s trade or business, other than debt
    secured by the taxpayer’s residences (as described
    above). Thus, interest subject to limitation generally
    includes investment interest subject to the section
    163(d) limitation under present law and consumer
    interest, such as interest paid or incurred to purchase
    an automobile for personal use. * * * [Id. at 299-300.]
    The House of Representatives passed H.R. 3838 without
    amendment to section 402 of H.R. 3838 as reported by the Ways and
    Means Committee.
    (4)   The Senate’s Amendment
    H.R. 3838 was received in the Senate on December 18, 1985,
    and referred to the Finance Committee.    Section 1421 of H.R. 3838
    as reported by the Finance Committee separated the above-noted
    considerations--investment interest and “consumer” interest.
    Section 1421(b) of the Finance Committee’s amendment revised
    section 163(d) but, unlike the House-passed bill, left that Code
    provision as one dealing with investment interest.   Section
    1421(a) of the Finance Committee’s amendment proposed a new
    section 163(h), which provided in pertinent part as follows:
    SEC. 1421. LIMITATIONS ON DEDUCTION FOR NONBUSINESS
    INTEREST.
    (a) Disallowance of Deduction for Consumer Interest of
    Individuals.--Section 163 (relating to deduction for
    interest) is amended by redesignating subsection (h) as
    subsection (i) and by inserting after subsection (g) the
    following new subsection:
    - 59 -
    “(h) Disallowance of Deduction for Consumer
    Interest.--
    “(1) In general.--In the case of a taxpayer other
    than a corporation, no deduction shall be allowed under
    this chapter for consumer interest paid or accrued
    during the taxable year.
    “(2) Consumer interest.--For purposes of this
    subsection--
    “(A) In general.--The term ‘consumer
    interest’ means any interest allowable as a
    deduction under this chapter other than interest
    paid or accrued on indebtedness incurred or
    continued in connection with--
    “(i) the conduct of a trade or business
    (other than the trade or business of
    performing services as an employee), or
    “(ii) an activity described in section
    212.
    “(B) Exception for qualified residence
    interest.--The term ‘consumer interest’ shall not
    include any qualified residence interest.[”]
    The Senate Finance Committee report, provides, in pertinent
    part, as follows (S. Rept. 99-313, at 802-806 (1986), 1986-3 C.B.
    (Vol. 3) 1, 802-806):

    Other interest
    Under present law, no limitation is imposed under
    section 163(d) on the deductibility of interest on
    indebtedness incurred for other purposes, e.g. to
    purchase or carry consumption goods. Interest on
    indebtedness incurred in connection with the taxpayer’s
    - 60 -
    trade or business is also not subject to the section
    163(d) limitation under present law.

    *     *      *      *     *     *   *
    Although the committee believes it would not be
    advisable to subject to income tax imputed rental
    income with respect to consumer durables owned by the
    taxpayer, it does believe that it is appropriate and
    practical to address situations where consumer
    expenditures are financed by borrowing. By phasing out
    the present deductibility of consumer interest, the
    committee believes that it has eliminated from the
    present tax law a significant disincentive to saving.

    Explanation of Provisions
    In general
    The bill expands the scope of the interest
    limitation, and alters the calculation of the amount of
    the limitation. Under the bill, all nonbusiness
    interest is subject to the limitation on deductibility,
    including consumer interest and certain interest that
    is not treated as investment interest subject to
    limitation under present law. Interest subject to the
    limitation under the bill does not include interest on
    debt secured by the taxpayer’s principal residence (to
    the extent of its fair market value), and interest on
    debt secured by a second residence of the taxpayer (to
    the extent of its fair market value). Interest expense
    that is paid or incurred in carrying on a trade or
    business is not subject to the interest deduction
    limitation under the bill (except for interest
    attributable to certain limited business interests).
    In general, under the bill, consumer interest is
    not deductible, and the deduction for investment
    interest is limited to investment income for the year
    - 61 -
    with an indefinite carryforward of disallowed
    investment interest.
    Investment interest limitation
    Interest subject to the limitation.–-Under the
    bill, interest subject to the investment interest
    limitation is all interest (other than consumer
    interest and qualified residence interest) on debt not
    incurred in connection with the taxpayer’s trade or
    business. * * *
    *     *     *       *    *    *      *
    Consumer interest limitation
    Under the bill, consumer interest is not
    deductible. Consumer interest generally includes all
    interest not incurred or continued in connection with
    the conduct of a trade or business (other than the
    performance of services as an employee) * * *. Thus,
    consumer interest includes, for example, interest on a
    loan to purchase an automobile for personal use, and
    credit card interest incurred for personal expenses.
    In all material respects, section 1421 of H.R. 3838 as
    passed by the Senate on June 24, 1986, was identical to section
    1421 of H.R. 3838 as reported by the Senate Finance Committee.
    Section 1401 of the Senate amendment as reported by the
    Finance Committee proposed to add a new section, section 469,
    relating to limitations on losses and credits from passive
    activities.   Neither the House bill, nor the President’s
    Proposals contained a corresponding provision.    H. Conf. Rept.
    99-841, II-137 (1986), 1986-3 C.B. (Vol. 4) 137; Joint Committee
    on Taxation, Comparison of Tax Reform Provisions of H.R. 3838 as
    passed by the House and Senate (JCS-15-86), 51 (July 15, 1986).
    (Section 501 of the House-passed version of the bill did,
    - 62 -
    however, propose to deny excess passive activity losses for
    purposes of computing the amount of the alternative minimum
    taxable income.       See TRA 1986 sec. 701,

    323.)
    Section 1401 of the Senate amendment to H.R. 3838 as
    reported by the Finance Committee provides, in pertinent part, as
    follows:

    ACTIVITIES.
    *       *   *     *    *    *    *
    (h) Regulations.--The Secretary shall prescribe such
    regulations as may be necessary or appropriate to carry out
    provisions of this section, including regulations--
    (1) which specify what constitutes an activity or
    material participation for purposes of this section,
    (2) which provide that certain items of gross
    income will not be taken into account in determining
    income or loss from any activity (and the treatment of
    expenses allocable to such income), and
    (3) if necessary to prevent avoidance of this
    section, determining whether income, gain, or loss from
    a limited partnership or other passive activity is
    treated as described in subsection (c)(3).
    The Finance Committee report on H.R. 3838 did not explain
    how the regulations promulgated under section 469 were to
    allocate interest expense.        S. Rept. 99-313, at 713-746, supra,

    of the principal provisions of H.R. 3838 (Tax Reform
    Act of 1986), as agreed to by the House-Senate
    Conferees on August 16, 1986. As a general rule, this
    pamphlet does not describe agreements of the Conferees
    not to adopt a particular provision that was only in
    the House-passed bill or only in the Senate-passed
    bill, i.e., agreements to retain present law on
    particular issues.
    This pamphlet is provided for the use of the
    Members of the House and the Senate. The official
    legislative document on the conference decisions on
    H.R. 3838 will be the conference report on the bill

    [Joint Committee Summary at 18.]
    The conference committee report (H. Conf. Rept. 99-841,
    supra, 1986-3 C.B. (Vol. 4) 1) was published on September 18,
    1986.   Section 511 of the conference committee report corresponds
    to section 1421 of H.R. 3838 as passed by the Senate.   In large
    part, section 511(b) of the conference committee report tracks
    section 1421(a) of H.R. 3838 as passed by the Senate.   Section
    511(b) of the conference committee report presents a new section
    163(h), which provides in pertinent part as follows:
    (h) Disallowance of Deduction for Personal Interest.--
    (1) In general.--In the case of a
    taxpayer other than a corporation, no
    deduction shall be allowed under this chapter
    for personal interest paid or accrued during
    the taxable year.
    (2) Personal interest.–-For purposes of
    this subsection, the term “personal interest”
    means any interest allowable as a deduction
    under this chapter other than--
    (A) interest paid or accrued on indebtedness
    incurred or continued in connection with the
    conduct of a trade or business (other than the
    trade or business of performing services as an
    employee),
    (B) any investment interest (within the
    meaning of subsection (d)),
    - 65 -
    (C) any interest which is taken into account
    under section 469 in computing income or loss from
    a passive activity of the taxpayer,
    (D) any qualified residence interest (within
    the meaning of paragraph (3)), and
    (E) any interest payable under section
    6601 on any unpaid portion of the tax imposed
    by section 2001 for the period during which
    an extension of time for payment of such tax
    is in effect under section 6163 or 6166. [H.
    Conf. Rept. 99-841, at I-171 (1986).]
    The Joint Statement of Managers portion of the conference
    committee report provides, in pertinent part, as follows:
    House Bill
    Under the House bill, the deduction for nonbusiness
    interest of noncorporate taxpayers is limited to $10,000
    ($20,000 for joint returns), plus net investment income,
    plus certain deductible expenditures in excess of rental
    income from net lease property. * * *
    *    *     *     *      *   *   *
    Nonbusiness interest means all interest not incurred in
    the taxpayer’s trade or business, including the taxpayer’s
    share of interest of S corporations in whose management he
    does not actively participate, the taxpayer’s share of
    interest expense of limited partnerships in which he is a
    limited partner, and the taxpayer’s share of interest
    expense of certain trusts and other entities in which he is
    a limited entrepreneur.
    *    *     *     *      *   *   *
    Senate Amendment
    The Senate amendment provides that the deduction for
    investment interest of noncorporate taxpayers is limited to
    net investment income, plus certain deductible expenditures
    in excess of rental income from net lease property.
    Consumer interest is not deductible. Interest on debt
    secured by the taxpayer’s principal residence and a second
    - 66 -
    residence of the taxpayer (to the extent of their fair
    market values) is not subject to limitation.
    * * *   Consumer interest means interest not attributable
    to a trade   or business (other than the trade or business of
    performing   services as an employee) or to an activity
    engaged in   for profit.

    Personal interest
    The conference agreement follows the Senate amendment
    provision with respect to consumer interest (denominated
    personal interest under the conference agreement), with
    modifications and clarifications.
    Under the conference agreement, personal interest is
    not deductible. Personal interest is any interest, other
    than interest incurred or continued in connection with the
    conduct of a trade or business (other than the trade or
    business of performing services as a employee), investment
    interest, or interest taken into account in computing the
    taxpayer’s income or loss from passive activities for the
    year. Personal interest also generally includes interest on
    tax deficiencies.
    Personal interest does not include qualified residence
    interest of the taxpayer, nor does it include interest
    payable on estate tax deferred under sec. 6163 or 6166. [H.
    Conf. Rept. 99-841, at II-151 to II-154, supra, 1986-3 C.B.
    (Vol. 4) at 151-154.]
    In all material respects, section 511(b) as reported by the
    conference committee was identical to section 511(b) of H.R. 3838
    as ultimately enacted, on October 22, 1986.       TRA 1986 sec.

    The conference agreement on H.R. 3838 generally follows
    section 1401 of the Senate amendment, relating to limitations on
    losses and credits from passive activities, but with certain
    modifications and clarifications.      H. Conf. Rept. 99-841, at II-
    138, supra, 1986-3 C.B. (Vol. 4) at 138.      As modified, clarified,

    The Joint Statement of Managers portion of the conference
    committee report explaining interest expense allocation under
    section 469 provides--
    Expenses allocable to portfolio income.–-The
    conference agreement provides that portfolio income is
    reduced by the deductible expenses (other than
    interest) that are clearly and directly allocable to
    such income. Properly allocable interest expense also
    reduces portfolio income. Such deductions accordingly
    are not treated as attributable to a passive activity.
    The conferees anticipate that the Treasury will
    issue regulations setting forth standards for

    1987, Pub. L. 100-203,

    sec. 469(k)(4) as sec. 469(l)(4).
    - 68 -
    appropriate allocation of expenses and interest under
    the passive loss rule. The conferees anticipate that
    regulations providing guidance to taxpayers with
    respect to interest allocation will be issued by
    December 31, 1986. These regulations should be
    consistent with the purpose of the passive loss rules
    to prevent sheltering of income from personal services
    and portfolio income with passive losses. Moreover,
    the regulations should attempt to avoid inconsistent
    allocation of interest deductions under different Code
    provisions.4
    In the case of entities, a proper method of
    allocation may include, for example, allocation of
    interest to portfolio income on the basis of assets,
    although there may be situations in which tracing is
    appropriate because of the integrated nature of the
    transactions involved. Because of the difficulty of
    recordkeeping that would be required were interest
    expense of individuals allocated rather than traced, it
    is anticipated that, in the case of individuals,
    interest expense generally will be traced to the asset
    or activity which is purchased or carried by incurring
    or continuing the underlying indebtedness.

    For example, an interest deduction that is disallowed
    under section 265 [relating to expenses and interest
    relating to tax-exempt income] or 291 [relating to
    special rules relating to corporate preference items]
    should not be allowed, capitalized, or suspended under
    another provision. [H. Conf. Rept. 99-841, at II-146,

    (6) 1986 Blue Book
    On May 4, 1987, the staff of the Joint Committee on Taxation
    published its General Explanation of the Tax Reform Act of 1986
    (1986 Blue Book), which states in pertinent part as follows (pp.
    262-264, 266):
    C.   Interest Deduction Limitations (Sec. 511 of the Act and
    secs. 163(d) and (h) of the Code)55
    - 69 -
    Prior Law
    *      *      *      *      *   *   *
    Other interest
    Under prior law, no limitation was imposed under
    section 163(d) on the deductibility of interest on
    indebtedness incurred for other purposes, e.g. to purchase
    or carry consumption goods. Under prior and present law,
    interest on indebtedness incurred in connection with the
    taxpayer’s trade or business is also not subject to the
    limitation on the deductibility of interest expense under
    section 163.
    Reasons for Change
    *      *      *      *      *   *   *
    Personal interest
    Prior law excluded or mismeasured income arising from
    the ownership of housing and other consumer durables.
    Investment in such goods allowed consumers to avoid the tax
    that would apply if funds were invested in assets producing
    taxable income and to avoid the cost of renting these items,
    a cost which would not be deductible in computing tax
    liability. Thus, the tax system under prior law provided an
    incentive to invest in consumer durables rather than assets
    which produce taxable income and, therefore, an incentive to
    consume rather than save.
    *      *      *      *      *   *   *
    Explanation of Provisions
    In general
    In general, under the Act, personal interest is not
    deductible, and the deduction for investment interest is
    limited to investment income for the year with an indefinite
    carryforward of disallowed investment interest. The
    personal interest limitation does not apply to interest on
    debt secured by the taxpayer’s principal residence (to the
    extent of its basis plus the amount of such debt used to pay
    certain educational or medical expenses) and interest on
    debt secured by a second residence of the taxpayer (to the
    - 70 -
    extent of its basis plus the amount of such debt used to pay
    certain educational or medical expenses), provided the total
    amount of such debt does not exceed the fair market value of
    such residence.
    *       *   *     *      *   *   *
    Personal interest
    Under the Act, personal interest is not deductible.
    Personal interest is any interest, other than interest
    incurred or continued in connection with the conduct of a
    trade or business (other than the trade or business of
    performing services as an employee), * * * investment
    interest, or interest taken into account of computing the
    taxpayer’s income or loss from passive activities for the
    year. Thus, personal interest includes, for example,
    interest on a loan to purchase an automobile, interest on a
    loan to purchase a life insurance policy, and credit card
    interest, where such interest is not incurred or continued
    in connection with the conduct of a trade or business.
    Personal interest also includes interest on underpayments of
    individual Federal, State or local income taxes
    notwithstanding that all or a portion of the income may have
    arisen in a trade or business, because such taxes are not
    considered derived from the conduct of a trade or
    business.60 However, personal interest does not include
    interest payable on estate tax deferred under sections 6163
    or 6166.
    Personal interest does not include qualified residence
    interest of the taxpayer, as discussed below.

    Personal interest does not include interest on taxes,
    other than income taxes, that are incurred in connection
    with a trade or business. (For the rule that taxes on net
    income are not attributable to a trade or business, see
    Treas. Reg. sec. 1.62-1(d), relating to nondeductibility of
    State income taxes in computing adjusted gross income.) In
    - 71 -
    addition, personal interest does not include interest of an
    S corporation which is attributable to an underpayment of
    income tax from a year in which the corporation was a C
    corporation or from the underpayment of the taxes imposed by
    sec. 1374 or 1375. Nor does personal interest include
    interest on an underpayment of income tax of a corporation
    payable by a shareholder by reason of transferee liability
    (under sec. 6901).
    (7)   TAMRA 1988
    On June 10, 1987, the Technical Corrections Act of 1987 was
    introduced in the House of Representatives (H.R. 2636) by Ways
    and Means Committee Chairman Rostenkowski and Congressman Duncan,
    and in the Senate (S. 1350) by Finance Committee Chairman Bentsen
    and Senator Packwood.   Section 105(c) of the bills provided as
    follows:
    SEC. 105.   AMENDMENTS RELATED TO TITLE V OF THE REFORM ACT.
    [The Tax Reform Act of 1986, see sec. 1(b)(2)
    of the bills.]
    *     *   *     *      *   *   *
    (c) Amendments Related to Section 511 of the Reform
    Act.--
    (1) Subparagraph (A) of section 163(d)(3) of the
    1986 Code (defining investment interest) is amended by
    striking out “incurred or continued to purchase or
    carry” and inserting in lieu thereof “properly
    allocable to”.
    *     *   *     *      *   *   *
    (4) Subparagraph (A) of section 163(h)(2) of the
    1986 Code is amended by striking out “incurred or
    continued in connection with the conduct of” and
    inserting in lieu thereof “properly allocable to”.
    - 72 -
    Section 119 of the bills provided that these amendments
    “shall take effect as if included in the provision of the Reform
    Act to which such amendment relates.”
    On June 15, 1987, the staff of the Joint Committee on
    Taxation released its Description of the Technical Corrections
    Act of 1987 (H.R. 2636 and S. 1350) (JCS-15-87), June 15, 1987.
    At pages 25 and 26, this staff pamphlet describes the above
    amendments as follows:
    Explanation of Provisions
    Investment interest.–-The bill conforms the
    language of the definition of investment interest to
    the language of a related provision that allocates
    interest expense to portfolio income under the passive
    loss rule. Thus, under the bill, investment interest
    is that which is properly allocable to property held
    for investment. This change results in consistency in
    the language of the provisions allocating interest
    expense to the category of investment interest, and
    permits consistent application of a standard for
    allocation of interest. This change is not intended to
    suggest the adoption of any particular method of
    allocation, but rather to give Treasury the ability to
    devise allocation rules as simple as possible
    consistent with the objectives of the provision.
    *       *   *     *      *   *   *
    Personal interest.–-The bill conforms the language
    of the definition of personal interest to the language
    of related provisions (the passive loss rule and the
    investment interest limitation) under which interest
    expense may be allocated. Thus, the bill provides that
    personal interest does not include interest that is
    properly allocable to a trade or business. This change
    results in consistency in the language of several
    significant provisions under which interest is likely
    to be allocated, and permits consistent application of
    a standard for allocation of interest.
    - 73 -
    As amended, the provisions of the House bill were included
    as Subtitle B of Title X (Revenue Provisions) of the Omnibus
    Budget Reconciliation Act of 1987 (H.R. 3545) as passed by the
    House in October 1987.   H. Rept. 100-795, at 2.   Paragraphs (1)
    and (4) of section 10205(c) of the House-passed H.R. 3545 are
    identical to the language of paragraphs (1) and (4) of section
    105(c) of H.R. 2636 set forth supra.    The description of the
    amendment to the definition of “personal interest” in the House
    Budget Committee’s report (the committee report for H.R. 3545) is
    identical to the description of the amendment in the staff
    pamphlet describing section 105(c)(4) of H.R. 2636 as introduced,
    set forth supra.   H. Rept. 100-391, at 1171 (1987).   The report’s
    description of the amendment to the definition of “investment
    interest” adds to the description in the staff pamphlet
    describing section 105(c)(1) of H.R. 2636 as introduced, set
    forth supra.   Id. at 1170.   Below is the committee report
    explanation of the amendment to the definition of “investment
    interest”; the underscored language signifies language that was
    not included in the staff pamphlet describing section 105(c)(1)
    of H.R. 2636 as introduced:
    Explanation of Provisions
    Investment interest.–-The bill conforms the
    language of the definition of investment interest to
    the language of a related provision that allocates
    interest expense to portfolio income under the passive
    loss rule. Thus, under the bill, investment interest
    is that which is properly allocable to property held
    - 74 -
    for investment. This change results in consistency in
    the language of the provisions allocating interest
    expense to the category of investment interest, and
    permits consistent application of a standard for
    allocation of interest. This change is not intended to
    suggest that the adoption of any particular method of
    allocation is required, but rather to give Treasury the
    ability to devise allocation rules as simple as
    possible consistent with the objectives of the
    provision. The committee believes that the Treasury
    should consider rules relating to the securing of
    property to mitigate some of the complexities of
    tracing where simplicity is desirable, so that, for
    example, any interest on a loan secured by personal use
    property could be considered personal interest, and any
    interest on a loan secured by investment assets could
    be considered investment interest. [H. Rept. 100-391,
    at 1170 (1987); emphasis added.]
    On December 4, 1987, Senate Budget Committee Chairman Chiles
    reported S. 1920 to the Senate; part II of subtitle B of title IV
    of S. 1920 as reported relates to technical amendments to TRA
    1986.   Paragraphs (1) and (4) of section 4665(c) of S. 1920 as
    reported are identical to the language of paragraphs (1) and (4)
    of section 105(c) of S. 1350 as introduced, set forth supra.      The
    paragraph of the document explaining the bill’s (S. 1920)
    amendment to the definition of “investment interest” as reported,
    except for two typographical errors, is identical to the
    corresponding paragraph of the House report, set forth supra.

    explaining the bill’s (S. 1920) amendment to the definition of

    “personal interest” is identical to both the corresponding
    paragraph in the House report and the staff pamphlet describing

    Cong., 1st Sess. at 272.
    As a result of a budget summit with the White House, the
    technical corrections were taken out of the budget reconciliation
    bill for 1987.   H. Rept. 100-495, at 1014 (1987), 1987-3 C.B. at
    294; 133 Cong. Rec. 34899 (Dec. 10, 1987) (colloquy between
    Finance Committee Chairman Bentsen and Senator Cranston.)    The
    Senate then considered S. 1920, and, after completing work on
    floor amendments, called up the House-passed bill (H.R. 3545),
    substituted the text of S. 1920 as amended, and asked for a
    conference.   133 Cong. Rec. 34935 (Dec. 10, 1987).   The Senate-
    passed amendment to H.R. 3545 did not include the technical
    corrections in S. 1920 and they were not included in the bill as
    enacted.   S. Rept. 100-445 at 3.
    On March 31, 1988, the Technical Corrections Act of 1988 was
    introduced in the House of Representatives (H.R. 4333) by Ways
    and Means Committee Chairman Rostenkowski and Congressman Duncan,
    and in the Senate (S. 2238) by Finance Committee Chairman Bentsen
    and Senator Packwood.   Paragraphs (1) and (4) of section 105(c)
    - 76 -
    of the bills were identical to paragraphs (1) and (4) of section
    105(c) of   H.R. 2636 and S. 1350 as introduced on June 10, 1987,
    set forth supra.
    Section 121 of the bills (H.R. 4333 and S. 2238) provided
    that these amendments “shall take effect as if included in the
    provision of the Reform Act to which such amendment relates.”
    On April 6, 1988, the staff of the Joint Committee on
    Taxation released its Description of the Technical Corrections
    Act of 1988 (H.R. 4333 and S. 2238) (JCS-10-88), March 31, 1988.
    At pages 34 and 35, the staff pamphlet descriptions of the above
    amendments are identical to the committee report explanations of
    the same amendments to the definitions of “investment interest”
    and “personal interest” as proposed in 1987, set forth supra.
    On July 26, 1988, the Ways and Means Committee reported H.R.
    4333 with an amendment that replaced the entire text of the
    introduced bill.   H. Rept. 100-795, at 1 (1988).   Paragraphs (1)
    and (4) of section 105(c) of the Committee’s amendment are
    identical to the introduced bill’s language and to paragraphs (1)
    and (4) of section 105(c) of H.R. 2636 and S. 1350 as introduced
    on June 10, 1987, set forth supra.     The Committee’s report
    states, in pertinent part, as follows (H. Rept. 100-795, at 3
    (1988)):

    II. EXPLANATION OF THE BILL
    TITLE I.–-TECHNICAL CORRECTIONS TO THE TAX REFORM ACT
    OF 1986
    The technical correction titles (Title I and Title
    II)[2] contain clerical, conforming and clarifying
    amendments to the provisions enacted by the Tax Reform
    Act of 1986 (P.L. 99-514) and other recently enacted
    legislation. All amendments are [sic] made by these
    titles are meant to carry out the intent of Congress in
    enacting the original legislation. Therefore, no
    separate “Reasons for Change” is set forth for each
    individual amendment. Except as otherwise described,
    the amendments made by the technical correction titles
    will take effect as if included in the original
    legislation to which each amendment relates.
    The report’s descriptions of the amendments to the
    definitions of “investment interest” and “personal interest” are
    identical to the descriptions in the staff pamphlet describing
    the introduced bill which are identical to the 1987 committee
    report descriptions of the same amendments, set forth supra.
    H. Rept. 100-795, at 34, 35 (1988).
    On August 3, 1988, the Finance Committee reported S. 2238
    with an amendment that replaced the entire text of the introduced
    bill.    S. Rept. 100-445, at 1 (1988).   Paragraphs (1) and (4) of
    section 105(c) of the Committee’s amendment are identical to the
    introduced bill’s language and to paragraphs (1) and (4) of
    section 105(c) as introduced in 1987 in H.R. 2636 and S. 1350,
    2
    The Ways   and Means Committee’s amendment added titles III
    (Substantive Tax   Provisions) and IV (Ways and Means Subcommittee
    Provisions), and   changed the short title of the bill (sec. 1(a))
    to Miscellaneous   Revenue Act of 1988.
    - 78 -
    set forth supra.   The first paragraph of the Committee report’s
    explanation of the bill is identical to the corresponding
    paragraph of the Ways and Means Committee’s report which is
    identical to the Committee report explanations of the same
    amendment as introduced on June 10, 1987 in H.R. 2636 and S.
    1350, set forth supra.3    S. Rept. 100-445, at 4 (1988).
    The Finance Committee report’s descriptions of the
    amendments to the definitions of “investment interest” and
    “personal interest” are identical to the descriptions in the
    staff pamphlet describing the introduced bill which are identical
    to the 1987 committee report explanations of the same amendments,
    set forth supra.   Id. at 35, 36.
    The Senate considered S. 2238 and, after completing work on
    floor amendments, called up the House-passed bill (H.R. 4333),
    substituted the text of S. 2238 as amended, passed H.R. 4333 as
    so amended, and asked for a conference.    134 Cong. Rec. 29792
    (Oct. 11, 1988).   The House and Senate amendments to the
    investment interest and personal interest definitions being
    identical, they were approved without further explanation by the
    conference committee.     H. Conf. Rept. 100-1104, Vol. I at 53, 54,
    3
    The Finance Committee’s amendment added titles III
    (Corrections to Collection and Exemption Procedures for Excise
    Taxes on Diesel and Nongasoline Aviation Fuels), IV (Other
    Corrections and Modifications), V (Railroad Unemployment and
    Retirement Amendments), and VI (Social Security Act Amendments),
    but did not change the short title of the bill (sec. 1(a)).

    Technical Corrections (JCX-30-88), 2 (1988).
    The above-described amendments were enacted by paragraphs
    (1) and (4) of section 1005(c) of the Technical and Miscellaneous
    Revenue Act of 1988 (TAMRA 1988), Pub. L. 100-647,

    RUWE, J., concurring:   I agree with the result reached by
    the majority; however, I cannot agree with the majority’s
    suggestion that the personal nature of the underlying income tax
    deficiency and the related interest plays no role in determining
    the validity of section 1.163-9T(b)(2)(i)(A), Temporary Income
    Tax Regs., 
    52 Fed. Reg. 48407
     (Dec. 22, 1987).   On the contrary,
    as I made clear in my dissenting opinion in Redlark v.
    Commissioner, 
    106 T.C. 31
    , 58, 60 (1996), I believe this to be a
    relevant and important factor.   The Courts of Appeals that have
    addressed this issue seem to agree.    See Kikalos v. Commissioner,
    
    190 F.3d 791
    , 797-798 (7th Cir. 1999), revg.

    - 81 -
    THORNTON, J., concurring:   I am concerned that the majority
    opinion may contribute to confusion over the interpretive weight
    this Court will accord nonauthoritative congressional staff
    materials.
    In its analysis, the majority opinion relies heavily on
    certain language appearing in the Joint Committee on Taxation
    General Explanation of the Tax Reform Act of 1986 (the Blue
    Book).   In Redlark v. Commissioner, 
    106 T.C. 31
    , 45-46 (1996),
    revd. and remanded 
    141 F.3d 936
     (9th Cir. 1998), this Court
    pointedly disregarded this same Blue Book language, stating:
    Where there is no corroboration in the actual
    legislative history, we shall not hesitate to disregard
    the General Explanation [of the Blue Book] as far as
    congressional intent is concerned. * * * Given the
    clear thrust of the conference committee report, the
    General Explanation [of the Blue Book] is without
    foundation and must fall by the wayside. To conclude
    otherwise would elevate it to a status and accord it a
    deference to which it simply is not entitled.
    Other opinions of this Court echo the notion that we require some
    direct corroboration of congressional intentions before we defer
    to Blue Book expressions thereof.   See Allen v. Commissioner, 
    118 T.C. 1
    , 15 (2002) (“Although the Staff of the Joint Committee’s
    explanation of a tax statute may be entitled to respect as a
    document that is prepared in connection with the legislative
    process by individuals who are intimately involved in that
    process, we shall not hesitate to disregard the expressions set
    forth therein where, as here, those expressions are barren of
    - 82 -
    corroboration in the legislative history.”); Zinniel v.
    Commissioner, 
    89 T.C. 357
    , 367 (1987) (“the portion of the
    General Explanation [of the Blue Book] * * *, standing alone,
    without any direct evidence of legislative intent, is not
    unequivocal evidence of legislative intent”), affd. 
    883 F.2d 1350
    (7th Cir. 1989).
    The majority opinion’s reliance on the Blue Book in
    overturning this Court’s decision in Redlark v. Commissioner,
    supra, raises at least three concerns:
    First, to the extent the majority opinion purports to find
    corroboration for the Blue Book language in a Joint Committee
    staff summary “published” during the conference on the 1986 Act
    (and not expressly considered in this Court’s Redlark opinion),
    it is unsatisfactory.   The Joint Committee staff summary is
    scarcely more reliable an indicator of congressional intentions
    than the Blue Book itself.   Like the Blue Book, the Joint
    Committee summary was a staff-generated document; it was released
    as a committee print rather than as a report; there is no
    indication that any Member of Congress approved it during
    consideration of the 1986 Act.   A mere proliferation (or more
    precisely, a mere doubling up) of staff-generated materials
    cannot supply the want of direct evidence of congressional
    intentions.
    - 83 -
    Second, to the extent the majority opinion means to
    repudiate the views of this Court as expressed in Redlark and
    other opinions, requiring some direct corroboration of Blue Book
    expressions of congressional intentions, it raises significant
    questions about the standard this Court now intends to apply in
    assessing the interpretive weight to accord materials like the
    Blue Book that technically are not part of the legislative
    history.   The only express clue provided by the majority opinion
    appears in its statement that “if a Blue Book were to conflict
    with enacted language or controlling legislative history, then
    the statutory language or the controlling legislative history
    would prevail.”    Majority op. p. 35.    This statement might be
    construed as suggesting that, even in the absence of direct
    corroboration in the statute or other controlling legislative
    materials, a Blue Book explanation will be considered as
    controlling unless it actually conflicts with these materials.
    Any such suggestion is troublesome.      As has been observed
    elsewhere, there should be no “one generic standard for assessing
    the Blue Book’s authority”; rather, the “Blue Book’s
    interpretative weight depends, in large measure, on the role it
    is performing.”    Livingston, “What’s Blue and White and Not Quite
    as Good as a Committee Report: General Explanations and the Role
    of ‘Subsequent’ Tax Legislative History”, 11 Am. J. Tax Poly. 91,
    105, 122 (1994).    Where, as here, a Blue Book explanation does
    - 84 -
    more than merely collate materials from the official committee
    reports or clarify inconsistencies therein, and instead purports
    to add a new gloss to the statute, we should be free to disregard
    the Blue Book explanation or at least accord it greatly reduced
    interpretive weight.
    Third, the stark divergence between this Court’s analysis in
    Redlark, where we felt compelled to disregard the Blue Book
    language altogether, and in the majority opinion, which appears
    to treat it as a substantial component of its analysis, might be
    thought to largely account for the different results then and
    now.    As demonstrated, however, by the decisions of the five
    courts of appeal to address this issue, which have coalesced
    around a straightforward analysis of judicial deference to agency
    actions, the Blue Book language (with or without the Joint
    Committee summary) is not dispositive of the validity of the
    Treasury regulations (which is, after all, the issue before us).
    Rather, the Treasury regulations are ultimately validated as
    reasonably interpreting a facially ambiguous statute.    The Blue
    Book language in question, while supportive of this result, is
    not essential to it.    By unduly elevating the Blue Book’s role in
    our analysis, we risk giving encouragement to inventive counsel
    in future cases to troll deeply for other types of
    noncontrolling legislative materials that might be argued to
    betoken congressional intent.
    GERBER and GALE, JJ., agree with this concurring opinion.
    - 85 -
    WELLS, C.J., dissenting:     I respectfully dissent from the
    majority’s refusal to follow Redlark v. Commissioner, 
    106 T.C. 31
    (1996), revd. and remanded 
    141 F.3d 936
     (9th Cir. 1998).      The
    meaning of section 163(h)(2)(A) can be discerned from a plain
    reading of the language of that section.      Moreover, prior caselaw
    defined the required nexus between an interest expense on a
    deficiency and a trade or business, and Congress did not indicate
    any intent to overturn these cases.      Also, the majority placed
    undue emphasis and reliance on the Blue Book in validating
    section 1.163-9T(b)(2)(i)(A), Temporary Income Tax Regs., 
    52 Fed. Reg. 48407
     (Dec. 22, 1987) in contravention of precedent.
    The majority contends that the language of section
    163(h)(2)(A) is ambiguous, but the majority provides little
    analysis of the statute itself.    Section 163(h)(2)(A) provides as
    follows:
    Sec. 163(h) Disallowance of Deduction for Personal
    Interest. -–
    (1) In general.-–In the case of a taxpayer other
    than a corporation, no deduction shall be allowed under
    this chapter for personal interest paid or accrued
    during the taxable year.
    (2) Personal interest.-–For purposes of this
    section, the term “personal interest” means any
    interest allowable as a deduction under this chapter
    other than–
    (A) interest paid or accrued on indebtedness
    properly allocable to a trade or business (other
    than the trade or business of performing services
    as an employee).
    - 86 -
    Petitioners contend that they should be permitted to deduct
    interest paid on a deficiency arising from disallowed Schedule C
    deductions relating to a sole proprietorship, a law firm.
    Although section 163(h)(1) disallows personal interest
    deductions, the reach of that section is truncated by section
    163(h)(2)(A), which excepts interest “properly allocable” to a
    trade or business from the definition of personal interest.
    Congress did not provide a definition for interest “properly
    allocable” to a trade or business.      In interpreting what Congress
    meant by “properly allocable” to a trade or business, however,
    courts should give the phrase “properly allocable” its usual or
    plain meaning.    United States v. Urrabazo, 
    234 F.3d 904
     (5th Cir.
    2000).   A reasonable reading of the phrase “properly allocable”
    would conclude that the phrase means fairly or correctly relating
    to a trade or business.    Interest paid on deficiencies arising
    from deductions taken by a sole proprietorship should fall within
    this class of interest.    Courts should only depart from the plain
    language of a statute to, “avoid a result so bizarre that
    Congress could not have intended it”.      Withrow v. Roell, 
    288 F.3d 199
    , 203 (5th Cir. 2002).    Reaching the conclusion that the
    interest paid on a deficiency arising from a sole proprietorship
    is “properly allocable” to a trade or business is surely not a
    bizarre result.
    The intent of Congress is best determined by examining the
    language of the statute.    Dial One of the Mid-South, Inc. v.
    - 87 -
    BellSouth Telecomms., Inc., 
    269 F.3d 523
     (5th Cir. 2001).
    Congress defined the types of interest excepted from “personal
    interest” by direct references to other code sections, except for
    interest “properly allocable” to trade or business income.        From
    this it can be inferred that the intent of Congress was to use
    the plain meaning of the term “properly allocable” to trade or
    business interest.   In section 163(h)(2)(B), Congress refers to
    section 163(d) for a definition of investment interest.      In
    section 163(h)(2)(C), Congress refers to section 469 for the
    definition of portfolio interest.    In section 163(h)(2)(D),
    Congress refers to section 163(h)(3) for a definition of
    qualified residence interest.    In section 163(h)(2)(E), Congress
    refers to section 6601.   Finally, in section 163(h)(2)(F),
    Congress refers to section 221 for a definition of interest on
    educational loans.
    Congress also provided some indication of what constitutes
    interest “properly allocable” to trade or business in section
    469(e), relating to the passive activity loss rules.    The meaning
    of “properly allocable” may be determined    by looking at
    adjoining words and phrases.    Simmons v. United States, 
    308 F.2d 938
    , 943-944 (5th Cir. 1962).    Sections 469(e)(1)(A)(i)(II) and
    (III) provide:
    Sec. 469(e) Special Rules for Determining Income or Loss
    From a Passive Activity.--For purposes of this section–-
    (1) Certain income not treated as income from
    - 88 -
    passive activity.-- In determining the income or loss
    from any activity.--
    (A) In general.-- There shall not be taken
    into account–-
    (i) any–
    *    *    *     *      *    *    *
    (II) expenses (other than interest)
    which are clearly and directly allocable
    to such gross income, and
    (III) interest expense properly
    allocable to such gross income * * *
    In 1986, section 469(e) was enacted concurrently with
    section 163(h)(2)(A).    As originally enacted, section
    163(h)(2)(A) read “incurred or continued in connection with the
    conduct of” and was changed in 1988 to “properly allocable”.1
    This was done in an effort to harmonize section 163(h)(2)(A) with
    section 469(e).
    When Congress enacted section 469(e) and later amended
    section 163(h)(2)(A), it had the opportunity to place limits on
    the relationship that an interest expense must bear to the
    conduct of an active trade or business.        Congress explicitly
    limited the “clearly and directly allocable” standard to business
    expenses and the “properly allocable” standard to interest
    expenses.   It reasonably can be inferred that “clearly and
    1

    102 Stat. 3342
    , 3390, H. Rept.
    100-795, at 33-37 (1988).
    - 89 -
    directly allocable” is more restrictive than “properly
    allocable”.   Congress could have used the same standard, “clearly
    and directly” in sections 469(e) and 163(h)(2)(A), yet, instead,
    used the “properly allocable” standard for section 163(h)(2)(A).
    Case law prior to the enactment of section 163(h)(2)(A)
    defined the nexus between an interest expense and a trade or
    business.   An interest expense arising from a deficiency related
    to a trade or business was treated like other business expenses
    and could be deducted by a sole proprietorship.       Standing v.
    Commissioner, 
    28 T.C. 789
     (1957, affd. 
    259 F.2d 450
     (4th Cir.
    1958); see Polk v. Commissioner, 
    31 T.C. 412
     (1958), affd. 
    276 F.2d 601
     (10th Cir. 1960); see also Reise v. Commissioner, 
    35 T.C. 571
     (1961), affd. 
    299 F.2d 380
     (7th Cir. 1962).      The above
    cases relied on sections 22(n)(1), 23(a)(1)(A) and 122(d)(5) of
    the Internal Revenue Code of 1939.     This definition comports with
    the holding in United States v. Gilmore, 
    372 U.S. 39
    , 49 (1963),
    which provided that the relevant inquiry is whether “the origin
    and character of the claim with respect to which an expense was
    incurred * * * is the controlling basic test of whether the
    expense was ‘business’ or ‘personal’* * *”.     
    Id.
    Congress is considered to be aware of these cases and the
    decisions existing before enactment of legislation.       Dresser
    Indus. v. United States, 
    238 F.3d 603
     (5th Cir. 2001). Congress
    is considered to be aware of “all pertinent judgments by our
    - 90 -
    branch.”    United States v. Barlow, 
    41 F.3d 935
    , 943 (5th Cir.
    1994).     Thus, Congress is considered to have been aware of
    Standing, Polk, and Reise when enacting section 163(h)(2)(A).
    The majority contends that Standing, Polk, and Reise were
    rendered ineffective by the passage of section 163(h)(2)(A)
    because section 163(h)(2)(A) is different from the statutes on
    which the holdings of those cases were based, and thus this
    change in language indicates a change in the meaning of the
    statute.    Majority op. p. 29 (citing Russello v. United States,
    
    464 U.S. 16
     (1983)).    However, it is well settled that when
    Congress seeks to overturn prior case law, it must do so in an
    explicit manner; an implicit inference to change the status quo
    is impermissible.     Bush v. Oceans Intl., 
    621 F.2d 207
     (5th Cir.
    1980), see Sea-Land Serv., Inc. v. United States, 
    874 F.2d 169
    ,
    172-173 (3d Cir. 1989).    Where Congress intends to overturn prior
    law, it must do so in “clear, unmistakable, and unarguable
    language.”     United States v. Singleton, 
    165 F.3d 1297
    , 1302 (10th
    Cir. 1999).    Conference committee reports are valuable in
    determining if Congress intended to overturn prior law, Sea-Land
    Serv., Inc. v. United States, supra; see United States v.
    Edwards, 
    23 F.2d 477
     (8th Cir. 1927).
    Congress did not express any intention to overturn Standing,
    Polk, and Reise, in the conference committee reports or elsewhere
    in the legislative history of the Tax Reform Act of 1986 (1986
    - 91 -
    TRA), Pub. L. 99-514, sec. 501, 
    100 Stat. 2233
    .    Standing, Polk,
    and Reise, were based on statutory language which permitted a
    deduction for interest if it arose “in carrying on a trade or
    business” and “attributable to” the taxpayer’s trade or business.
    See secs. 23(a)(1)(A), 22(n), and 122(d)(5) of the Internal
    Revenue Code of 1939.   The majority argues that this language is
    different from the language “interest paid or accrued on
    indebtedness incurred or continued in connection with the conduct
    of a trade or business” and the Technical and Miscellaneous
    Revenue Act of 1988 (1988 TAMRA), Pub. L. 100-647, sec.
    1005(c)(4), 
    102 Stat. 3390
    , language, and because of this
    difference, the sections have a different meaning.
    In Russello, the Supreme Court analyzed the substantive
    differences between the two provisions in question.    Russello v.
    United States, supra at 22-24 (examining the substantive changes
    and history of 18 U.S.C. sec. 1963(a)(1) (1970), the Racketeer
    Influenced Corrupt Organization statute).   In Russello, the
    Supreme Court determined that Congress expanded a provision
    beyond its original scope.   Id.   The majority has not engaged in
    such an analysis.   Additionally, the Supreme Court was construing
    language in the same statute in Russello; whereas, in the instant
    case, there are several statutes in question.
    Moreover, it is not necessarily clear that the pre-1986 TRA
    language is substantively different from the 1986 TRA language
    - 92 -
    and the 1988 TAMRA language.   The argument that a simple change
    indicates a different meaning seems to fail in the context of
    1986 TRA and 1998 TAMRA, where Congress replaced “interest paid
    or accrued on indebtedness incurred or continued in connection
    with the conduct of a trade or business” in section 163(h)(2)(A)
    with “properly allocable”.   The 1988 TAMRA conference committee
    report does not indicate an intent to change the meaning or reach
    of section 163(h)(2)(A).   However, reverting to the plain meaning
    of these two phrases, it is reasonable to assert that they have
    the same meaning even though the language is different.    The same
    should be true for the pre-1986 TRA language.
    The majority concludes that the language of section
    163(h)(2)(A) is ambiguous, which requires an examination of the
    legislative history of the section 163(h)(2)(A), as mandated by
    Chevron U.S.A. v. Natural Res. Def. Council, 
    467 U.S. 837
     (1984).
    The Joint Statement of Managers of the Conference Report, H.
    Conf. Rept. 99-841, at II-151 to II-154 (1986), 1986-3 C.B. (Vol.
    4) 154, published September 18, 1986 (Conference Committee
    Report), provides:
    Under the conference agreement, personal interest is
    not deductible. Personal interest is any interest, other
    than interest incurred or continued in connection with the
    conduct of a   trade or business (other than the trade or
    business of performing services as a employee), investment
    interest, or interest taken into account in computing the
    taxpayer’s income of loss from passive activities for the
    year. Personal interest also generally includes interest on
    tax deficiencies.
    - 93 -
    The majority argues that the use of the term “deficiencies”
    in the Conference Committee Report may be unclear and that
    “generally” only excludes certain types of estate taxes from
    “personal interest”.   Majority op. pp. 33-34.     The effect of
    these arguments is to restrain the force of the Conference
    Committee Report in determining the reach of what is “properly
    allocable” to a trade or business.
    The term deficiency means “the amount by which the income,
    gift, or estate tax due under the law exceeds the amount of such
    tax shown on the return.”    Bregin v. Commissioner, 
    74 T.C. 1097
    ,
    1101-1102 (1980).   The plain language of the Conference Committee
    Report supports petitioners because it excepts from personal
    interest “interest incurred or continued in connection with the
    conduct of a trade or business.”    H. Conf. Rept. 99-841, at II-
    154, supra, 1986-3 C.B. (Vol. 4) at 154.     The interest was
    incurred as a result of a tax deficiency arising from the
    operation of a sole proprietorship.     The final sentence in the
    above passage does not detract from this reading.     “Generally” is
    defined as “in disregard of specific instances and with regard to
    an overall picture.”   Webster’s Tenth Collegiate Dictionary 485
    (1998).   The use of the term “generally” indicates that the
    conference committee understood that personal interest usually
    includes interest on tax deficiencies; however, there are
    exceptions to this rule.    A reasonable inference would be that
    - 94 -
    interest on tax deficiencies arising from a sole proprietorship
    are not within personal interest because the previous sentence
    excepted that class of interest from “personal interest”.    If the
    conference committee intended all interest on deficiencies to be
    included in personal interest, then the conference committee
    could have left the word “generally” out of the last sentence, so
    that personal interest would cover all interest on deficiencies.
    The majority holds that the Conference Committee Report is
    not clear and accordingly justifies its reliance on the Joint
    Committee on Taxation General Explanation of the Tax Reform Act
    of 1986, pp. 262-264, 266, published May 4, 1987 (Blue Book).
    Majority op. p. 35.    The majority argues that the confusion is
    further exacerbated because the Blue Book provides that interest
    on a tax deficiency relating to a sole proprietorship is
    considered personal interest.    The majority goes too far in
    rejecting the Conference Committee Report in favor of the Blue
    Book.
    In upholding the validity of section 1.163-9T(b)(2)(i)(A),
    Temporary Income Tax Regs., supra, and refusing to follow Redlark
    v. Commissioner, 
    106 T.C. 31
     (1996), the majority provides:
    As applied to the instant case, section 1.163-
    9T(b)(2)(I)(A), Temporary Income Tax Regs., supra, treats
    petitioners’ payment of interest as nondeductible “personal
    interest”. The text of section 163(h)(2)(A) does not compel
    this result. The relevant legislative history, however,
    lends some support to this interpretation of the statute.
    [Majority op. pp. 47-48.]
    - 95 -
    The “legislative history” the majority relies on is the
    material contained in the Blue Book and in the Joint Committee on
    Taxation, Summary of Conference Agreement on H.R. 3838 (Tax
    Reform Act of 1986) (JCS-16-86), August 29, 1986 (Staff Summary).
    The Blue Book was published by congressional staff after the
    enactment of 1986 TRA.    The majority argues the Staff Summary,
    which was produced before 1986 TRA was enacted, corroborates
    assertions made in the Blue Book regarding personal interest.
    Such reliance is unwarranted and contrary to precedent.       A
    staff committee’s explanation of a provision is not a statement
    by legislators and was not relied on by legislators when enacting
    the 1986 TRA because it was published in May 1987.     McDonald v.
    Commissioner, 
    764 F.2d 322
     (5th Cir. 1985), affg. T.C. Memo 1983-
    197; see Zinniel v. Commissioner, 
    89 T.C. 357
     (1987).      A staff
    summary explanation provided after the enactment of a provision
    is not legislative history.     Guilzon v. Commissioner, 
    985 F.2d 819
     (5th Cir. 1993), affg. 
    97 T.C. 237
     (1991); see Zinniel v.
    Commissioner, supra.     The Staff Summary explanation cannot be
    considered part of the legislative history because it was
    authored by Congressional staff, the staff of the Joint Committee
    on Taxation, and not by Congress.     Estate of Hutchinson v.
    Commissioner, 
    765 F.2d 665
     (7th Cir. 1985), affg. 
    T.C. Memo. 1984-55
    .   The Staff Summary, however, may be given some
    - 96 -
    deference, especially when the staff views expressed are
    consistent with items of legislative history.   
    Id.
    I agree with Judge Thornton’s concurring opinion to the
    extent that he concludes that the majority’s reliance on the Blue
    Book is misplaced.   The Blue Book represents only the view of the
    Congressional staff; it was not approved by Congress.
    Furthermore, the Blue Book could not have been relied upon by
    Congress because it was published during the 100th Congress and
    the Tax Reform Act was enacted by the 99th Congress.    Also, the
    Blue Book should not be relied on because it is inconsistent with
    the Conference Committee Report, which would not treat interest
    on a tax deficiency arising from a sole proprietorship as
    personal interest, whereas the Blue Book would treat such
    interest as personal interest.2   Consequently, the majority’s
    reliance on the Blue Book in validating section 1.163-
    9T(b)(2)(i)(A), Temporary Income Tax Regs., supra, must be
    rejected.
    Section 1.163-9T(b)(2)(i)(A), Temporary Income Tax Regs.,
    supra, was not promulgated as part of a legislative mandate
    permitting the Commissioner to write regulations.     Rather, those

    The Blue Book provides: “Personal interest also includes
    interest on underpayments of individual Federal, State, or local
    income taxes notwithstanding that all or a portion of the income
    may have arisen in a trade or business, because such taxes are
    not considered derived from the conduct of a trade or business.”

    Reform Act of 1986, at 266. (J. Comm. Print 1987).
    - 97 -
    regulations were promulgated pursuant to the Commissioner’s
    section 7805(a) general power to promulgate interpretative
    regulations.    An interpretative regulation warrants less
    deference than legislative regulation.     United States v. Vogel
    Fertilizer Co., 
    455 U.S. 16
    , 24 (1982).     Congress did grant the
    Commissioner the power to enact legislative regulations with
    respect to some provisions of section 163, but not with regard to
    section 163(h)(2)(A).3    The Commissioner has not promulgated
    permanent regulations despite the fact that this temporary
    regulation was first promulgated in 1987.
    Finally, the majority’s validation of section 1.163-
    9T(b)(2)(I)(A), Temporary Income Tax Regs., supra, begs a
    significant policy question, and that is whether Congress ever
    intended to deny individuals doing business through sole
    proprietorships the advantages they would enjoy had they engaged
    as a corporate form.     See Redlark v. Commissioner, 
    106 T.C. 31
    ,
    40-41 (1996).    In the year before 1986 TRA was enacted, there
    were 11,928,738 nonfarm sole proprietorship returns filed with
    the Internal Revenue Service,4 and as of 1999, there were
    17,575,643 nonfarm sole proprietorship returns filed with the

    Internal Revenue Service.5   It is difficult to imagine that
    Congress was not aware of the number of individuals engaged in
    sole proprietorships in 1986.    It is even more difficult to
    comprehend that Congress would deny this large segment of the
    business world a deduction for interest, which I believe is
    clearly allocable to a trade or business, without more discussion
    in the legislative history, or at least a clear directive to the
    Commissioner to effect such a policy.    To permit such a result is
    to allow the Commissioner to make an end run around the
    legislative powers of Congress.
    For the foregoing reasons, I respectfully dissent.
    SWIFT, COLVIN, LARO, and VASQUEZ, JJ., agree with this
    dissenting opinion.

    SWIFT, J., dissenting:    Mainly for the reasons set forth in
    my prior concurring opinion in Redlark v. Commissioner, 
    106 T.C. 31
    , 48-49 (1996), revd. and remanded 
    141 F.3d 936
     (9th Cir.
    1998), I believe petitioners’ income tax deficiency interest
    should be regarded as properly allocable to petitioners’ business
    under section 163(h)(2)(A) and as deductible under section
    163(a).
    None of the five Courts of Appeals’ opinions cited by the
    majority, or the instant majority opinion, persuades me to the
    contrary.   Within the jurisdictions of the other seven geographic
    Courts of Appeals, taxpayers still are entitled to rely on our
    Court-reviewed Redlark opinion, and that is exactly what Mr. and
    Mrs. Robinson have done.     Lardas v. Commissioner, 
    99 T.C. 490
    ,
    495 (1992).
    Two separate but related facts in this case are clear and
    undisputed:   (1) Under the express and clear language of section
    163(h)(2)(A), if an interest expense is “properly allocable” to a
    trade or business, the interest expense is deductible; and
    (2) the tax adjustments giving rise to petitioners’ 1987 tax
    deficiency arose directly from and in connection with
    petitioners’ law business.    Accordingly, some portion of the
    related interest expense should be allocable to the business and
    should be deductible.
    Under respondent’s “temporary” regulation, section 1.163-
    9T(b)(2)(i)(A), Temporary Income Tax Regs., 
    52 Fed. Reg. 48409
    - 100 -
    (Dec. 22, 1987), outstanding now for 15 years, petitioners’
    interest expense is nondeductible regardless of the fact that it
    was incurred by petitioners in connection with the business.
    Respondent’s temporary regulation and position herein should be
    rejected as an erroneous attempt to redefine the substantive
    provision of section 163(h)(2)(A).
    Respondent’s temporary regulation may provide reasonable
    methods for allocating interest between a taxpayer’s business and
    a taxpayer’s other activities, but if there is no question as to
    what an item of interest expense relates to, then the statute is
    clear and requires an allocation between the business and the
    nonbusiness portions thereof, and the portion allocable to the
    taxpayer’s business is to be allowed as a deduction.
    Respondent’s temporary regulation, in a situation involving a
    sole proprietorship trade or business and a related income tax
    deficiency, improperly and contrary to the statute, establishes a
    per se interest expense disallowance rule and would leave no
    interest expense to be allocated.
    Respondent’s temporary regulation is also inconsistent with
    section 1.163-9T(b)(1)(i), Temporary Income Tax Regs., 
    52 Fed. Reg. 48409
     (Dec. 22, 1987), and with the allocation rule provided
    in the sister regulation relating to   situations where no loan
    proceeds are involved in an underlying transaction or activity
    (namely, where a seller or provider of goods or services provides
    financing to a taxpayer or where a transaction involves interest
    - 101 -
    expense associated with a mere extension of credit, not a
    provision of funds).   Section 1.163-8T(c)(3)(ii), Temporary
    Income Tax Regs., 
    52 Fed. Reg. 25001
     (July 2, 1987), provides as
    follows:
    If a taxpayer incurs or assumes a debt in consideration
    for the sale or use of property, for services, or for
    any other purpose, or takes property subject to a debt,
    and no debt proceeds are disbursed to the taxpayer, the
    debt is treated for purposes of this section as if the
    taxpayer used an amount of the debt proceeds equal to
    the balance of the debt outstanding at such time to
    make an expenditure for such property, services, or
    other purpose. [Emphasis added.]
    The above temporary regulation provides that in the
    situations (and for any purpose) where financing and credit
    transactions do not involve the disbursement of loan proceeds but
    do involve the extension of credit, interest expense relating to
    the extension of credit is to be allocated between the taxpayer’s
    business and personal activity based on the nature of the
    underlying activity giving rise to the extension of credit.
    Under section 1.163-8T(c)(3)(ii), Temporary Income Tax
    Regs., supra, as applicable to the instant case, even though no
    loan proceeds were disbursed by the Government to petitioners,
    credit was extended by the Government to petitioners, and
    petitioners were charged interest with regard thereto.
    Because the underlying activity in question in this case
    (giving rise to the tax deficiency and to the Government’s
    extension of credit to petitioners) undisputedly relates to
    - 102 -
    petitioners’ business, under section 1.163-8T(c)(3)(ii),
    Temporary Income Tax Regs., supra, some interest expense should
    be treated as properly allocable to petitioners’ business and as
    deductible under the statute.
    As suggested in Judge Vasquez’s dissenting opinion, in
    interpreting the statutory provisions in dispute herein, the
    occasional deference mandated by Chevron U.S.A., Inc. v. Natural
    Res. Def. Council, Inc., 
    467 U.S. 837
    , 842-843 (1984), to
    governmental agency interpretations of statutory language left
    ambiguous by Congress is not applicable.
    More recently, in United States v. Mead Corp., 
    533 U.S. 218
    (2001), the Supreme Court addressed the general and flexible
    standard to be used by courts in evaluating what deference, if
    any, should be given to agency interpretative regulations and
    rulings as follows:
    The fair measure of deference to an agency
    administering its own statute has been understood to
    vary with circumstances, and courts have looked to the
    degree of the agency’s care, its consistency,
    formality, and relative expertness, and to the
    persuasiveness of the agency’s position * * *. * * *
    [Id. at 228; fn. refs. omitted.]
    And further:
    “The weight [accorded to an administrative] judgment in
    a particular case will depend upon the thoroughness
    evident in its consideration, the validity of its
    reasoning, its consistency with earlier and later
    pronouncements, and all those factors which give it
    power to persuade, if lacking power to control.” [Id.
    at 228 (quoting Skidmore v. Swift & Co., 
    323 U.S. 134
    ,
    140 (1944)).]
    - 103 -
    Consistent with the above statement quoting Skidmore, and
    before concluding whether the particular agency rulings involved
    therein (of the Environmental Protection Agency and of the U.S.
    Customs Service, respectively) were entitled to Chevron type
    deference, in both Chevron and Mead the Supreme Court reviewed
    the very “detailed and reasoned” historical aspects of the E.P.A.
    ruling (Chevron U.S.A., Inc. v. Natural Res. Def. Council, Inc.,
    supra at 865), and the many “angles” of the classification ruling
    procedures of the U.S. Customs Service (United States v. Mead
    Corp., supra at 231).1
    In the instant case, however, with regard to respondent’s
    promulgation of section 1.163-9T(b)(2)(i)(A), Temporary Income
    Tax Regs., 
    52 Fed. Reg. 48409
     (Dec. 22, 1987), there is scant
    indication of respondent’s deliberations and degree of care
    exercised prior to promulgation of the temporary regulation.      No
    history of the development of the temporary regulation is
    available.    No hearing was held.   No notice and comment were
    provided.    No proposed regulation was made available.   No history
    of respondent’s development of the policy position reflected in
    the temporary regulation is available.     It appears to me that the
    statement in the 1987 Blue Book, discussed infra, and
    respondent’s failed litigating position in years prior to 1986 as
    1
    See Chevron U.S.A., Inc. v. Natural Res. Def. Council,
    Inc., 
    467 U.S. 837
    , part VI at 853-859 (1984); United States v.
    Mead Corp., 
    533 U.S. 218
    , part B at 231-234 (2001).
    - 104 -
    to the deductibility of income tax deficiency interest relating
    to an individual’s trade or business (see cases cited infra
    note 7) are the only historical “angles” that would support the
    per se disallowance rule of section 1.163-9T(b)(2)(i)(A),
    Temporary Income Tax Regs., supra.      That being the case, Chevron
    type deference is hardly appropriate.
    Of the Courts of Appeals that have addressed the issue
    before us, two inappropriately treat section 1.163-
    9T(b)(2)(i)(A), Temporary Income Tax Regs., supra, as a
    legislative regulation.   See Redlark v. Commissioner, 
    141 F.3d 936
    , 940 (9th Cir. 1998); Miller v. United States, 
    65 F.3d 687
    ,
    690 (8th Cir. 1995).   To the contrary, where it so intends,
    Congress knows how to specifically delegate legislative
    regulatory authority with regard to tax legislation, and nowhere
    in section 163(h) do we find such a delegation.     For examples of
    such specific delegation of legislative authority within just the
    other subsections of section 163, see section 163(f)(2)(C)
    (involving interest expense on certain types of obligations that
    are not in registered form); section 163(i)(5) (involving
    interest expense on certain types of corporate debt instruments
    with substantial original issue discount); and section 163(l)(5)
    (involving interest expense on certain types of corporate
    indebtedness payable in the equity of the debtor).
    Although upholding it, the Court of Appeals for the Seventh
    Circuit noted its concern with regard to the deference to be
    - 105 -
    given section 1.163-9T(b)(2)(i)(A), Temporary Income Tax Regs.,
    supra, as follows:
    In the absence of any confirmation that the temporary
    regulation has, after the fact, undergone the scrutiny
    that typifies a pre-adoption notice and comment period,
    one could argue that section 1.163-9T(b)(2)(i)(A) is
    entitled to no more deference than a proposed
    regulation. * * *
    Whatever questions the “temporary” nature of this
    regulation might raise as to the degree of deference it
    is owed, the parties themselves have chosen not to
    pursue them. * * * [Kikalos v. Commissioner, 
    190 F.3d 791
    , 796 (7th Cir. 1999), revg. 
    T.C. Memo. 1998-92
    .]
    With regard to the relevant legislative history relating to
    enactment in 1986 of subsection (h) of section 163, I submit that
    a reading thereof is available which has not yet been considered
    by the various courts addressing this issue and which:   (1) Would
    support a plain-meaning interpretation of section 163(h)(2)(A)
    (allowing the deduction of individual income tax deficiency
    interest relating to a trade or business), and (2) which would
    not support respondent’s per se disallowance rule.
    In the Joint Statement of Managers of the Conference Report,
    H. Conf. Rept. 99-841 (Vol. II) at II-154 (1986), 1986-3 C.B.
    (Vol. 4), 1, 154, published on September 18, 1986, the following
    statement is made:
    Under the conference agreement, personal interest
    is not deductible. Personal interest is any interest,
    other than interest incurred or continued in connection
    with the conduct of a trade or business * * * Personal
    interest also generally includes interest on tax
    deficiencies. [Emphasis added.]
    - 106 -
    The emphasized language in the above quotation from the
    legislative history can be read to indicate that Congress in 1986
    intended to carve out of the definition of personal interest all
    interest relating to a trade or business.   Once all trade or
    business interest is carved out of personal interest by the above
    emphasized language, the next sentence generally describing
    personal interest only reaches types of interest left over, but
    not business interest that already is carved out by the prior
    language.   With this reading of the legislative history, the last
    sentence in the above quotation (namely, “Personal interest also
    generally includes interest on tax deficiencies.”) may be read to
    reach only interest on tax deficiencies not related to a
    taxpayer’s trade or business.

    “In the case of deficiency interest, the
    Government essentially extends credit to a taxpayer and
    assesses interest for the extension of that credit.
    Thus, when the underlying activity which creates the
    deficiency relates to a taxpayer’s business, the
    interest is ‘allocable’ to the business and deductible
    under section 163(h)(2)(A).” [Quoting Allen v. United

    173 F.3d 533
     (4th Cir. 1999).] Since Temp. Reg. 1.163-
    9T(b)(2)(i)(A) is in direct conflict with an earlier-
    enacted regulation that also covers the deductibility
    of deficiency interest related to a trade or business,
    Temp. Reg. 1.163-9T(b)(2)(i)(A) cannot be considered a
    reasonable interpretation of the statute. [Newmark &
    Englebrecht, “Courts Split on Individuals’ Deficiency
    Interest Deduction”, 62 Prac. Tax Strat. 87, 95 (1999);
    fn. ref. omitted.]
    With regard to the Blue Book to the 1986 Act, and its
    peculiar origin, we noted in our original opinion, Redlark v.
    Commissioner, 
    106 T.C. at
    45 n.7, as follows:
    [W]e also note that the Tax Reform Act of 1986, Pub. L.
    99-514, 
    100 Stat. 2085
    , was enacted on Oct. 22, 1986,
    during the 99th Congress, whereas the General
    Explanation [the Blue Book] was published on May 4,
    1987, during the 100th Congress. Thus, the General
    Explanation is not even entitled to the respect it
    might otherwise be accorded if it had been prepared for
    the Congress which enacted sec. 163(h).
    See also Allen v. Commissioner, 
    118 T.C. 1
    , 14-15 (2002),
    involving the alternative minimum tax under section 55 and
    commenting on the limited usefulness of the Blue Book applicable
    to the 1986 Act.   Further with regard to the Blue Book, see the
    concurring opinion herein of Judge Thornton.
    - 109 -
    With regard to the legal context or climate which existed in
    1986, at the time subsection (h) of section 163 was added to the
    Code, another commentator has stated:
    The problem with the dissent’s reasoning [in our
    Redlark opinion, 
    106 T.C. 31
    ] is that, like the Eighth
    Circuit [in Miller v. United States, 
    65 F.3d 687
    , 689-
    690 (8th Cir. 1995)], it assumes that the statute is
    unclear. This assumption is based on the fact that
    section 163(h)(2)(A) defines personal interest by
    excluding business interest without providing a
    specific definition for business interest. The Eighth
    Circuit in Miller held that the absence of a definition
    of “business interest” created the ambiguity on which
    the IRS could hang its hat.
    As the Tax Court’s decision illustrates, however,
    Congress does not legislate in a vacuum. Under the
    prior case law, the interest on an income tax
    deficiency resulting from an adjustment involving a
    trade or business was treated as interest incurred in a
    trade or business. If Congress is deemed to have been
    aware of the law at the time it enacted Section
    163(h)(2)(A), there was no ambiguity in the statutory
    language. [Lipton, “Divided Tax Court Allows Deduction
    of Interest on Tax Arising From a Trade or Business”,
    84 J. Taxn. 218, 222 (1996).]
    Lastly, as I read it, the legislative history relating to
    the 1986 and the 1988 relevant legislative changes to section 163
    shows that Congress, in disallowing personal interest, was
    addressing “consumer” interest, not interest that was
    specifically attributable to a taxpayer’s trade or business.
    In sum, section 1.163-9T(b)(2)(i)(A), Temporary Income Tax
    Regs., 
    52 Fed. Reg. 48409
     (Dec. 22, 1987), is only
    interpretative.   After 15 years, it is still in temporary form.6

    section 1.163-9T(b)(2)(i)(A), Temporary Income Tax Regs., supra,

     (1996), revd. and remanded
    
    141 F.3d 936
     (9th Cir. 1998).    I continue to agree that section
    1.163-9T(b)(2)(i)(A), Temporary Income Tax Regs., 
    52 Fed. Reg. 48409
     (Dec. 22, 1987) (the 9T regulation), is invalid for the
    reasons stated in the majority and concurring opinions in
    Redlark.    I write separately, however, to address the appropriate
    standard of review applicable to the case at bar in light of the
    U.S. Supreme Court’s opinion in United States v. Mead Corp., 
    533 U.S. 218
     (2001), and the various Courts of Appeals’ opinions--
    including the Fifth, Seventh, Eighth, Ninth, and District of
    Columbia Circuit opinions--addressing Mead.
    I.   Mead
    In Mead, the U.S. Supreme Court clarified the limits of
    deference pursuant to Chevron U.S.A. Inc. v. Natural Res. Def.
    Council, Inc., 
    467 U.S. 837
     (1984), owed to an agency’s
    interpretation of a statute it administers.   The Court held that
    an agency’s interpretation of a particular statutory provision
    qualifies for Chevron deference when (1) Congress delegated
    authority to the agency to make rules carrying the force of law,
    and (2) the agency interpretation claiming deference was
    promulgated in the exercise of that authority.    United States v.
    Mead Corp., supra at 226-227.    Thus, the delegation of authority
    by Congress to the agency is insufficient in and of itself to
    - 113 -
    entitle the agency implementation to Chevron deference; the
    agency must also actually invoke the authority delegated.        Id. at
    226-227, 237.
    The Court clarified Chevron by stating that the delegation
    of authority may be either explicit or implicit, and when Chevron
    deference applies, a reviewing court is obliged to accept the
    agency’s position if Congress has not previously spoken to the
    point at issue and the agency’s interpretation is reasonable.
    Id. at 227, 229.      Thus, any regulation entitled to Chevron
    deference is binding on the courts unless procedurally defective,
    arbitrary or capricious in substance, or manifestly contrary to
    the statute.       Id. at 227.
    Precedential value alone, however, does not add up to
    Chevron entitlement; interpretive rules sometimes may function as
    precedents, and they enjoy no Chevron status as a class.       Id. at
    232.       Although not limiting Chevron deference to situations where
    notice-and-comment rulemaking or formal adjudications took place,
    the Court focused on these attributes and stated they are
    significant in determining whether Congress contemplated
    administrative action with the effect of law and whether Chevron
    deference is appropriate.1       Id. at 230, 231, 233, 234.
    1
    The Court cites numerous cases where notice-and-comment
    rulemaking took place, but only one where it did not, and
    Chevron deference was accorded. United States v. Mead Corp., 
    533 U.S. 218
    , 230 n.12, 231 n.13 (2001).
    - 114 -
    When an agency’s interpretation of a particular statutory
    provision does not qualify for Chevron deference, it still may
    merit some deference pursuant to Skidmore v. Swift & Co., 
    323 U.S. 134
     (1944).       United States v. Mead Corp., supra at 234-235,
    237.       Pursuant to Skidmore, the agency’s interpretation would be
    accorded respect proportional to its “power to persuade”.           Id. at
    235.
    II.    Chronology of the Case Law Pre-Mead
    A.      Miller--Eighth Circuit
    The U.S. Court of Appeals for the Eighth Circuit was the
    first Court of Appeals to address the validity of the 9T
    regulation.       Miller v. United States, 
    65 F.3d 687
     (8th Cir.
    1995).       The Court of Appeals for the Eighth Circuit relied on
    Chevron to determine the validity of the 9T regulation.           
    Id. at 689
    .       The court did not state that section 163(h)(2)(A) was
    ambiguous; instead, it concluded that Congress failed to define
    what constitutes “business interest”2 in the statute, and this
    was an implicit legislative delegation of authority to the
    Commissioner.       
    Id. at 690
    .   But see Judge Swift’s dissent p. 104.
    The court then relied on The General Explanation of the Tax
    Reform Act of 1986 (Blue Book) issued by the staff of the Joint
    Committee on Taxation to conclude that the 9T regulation was a
    permissible construction of the statute.        
    Id. at 690-691
    .
    2
    It is unclear why the court chose to focus on “business
    interest” rather than “personal interest”.
    - 115 -
    B.   Redlark
    1.      Tax Court
    In Redlark, we noted that the 9T regulation was an
    interpretive, rather than a legislative, regulation.         Redlark v.
    Commissioner, 
    106 T.C. at 38
    .      We respectfully disagreed with the
    Court of Appeals for the Eighth Circuit’s conclusion and held
    that the 9T regulation was unreasonable and an impermissible
    reading of the statute.       
    Id. at 47
    .
    In dissent, Judge Halpern stated that in the absence of
    temporary regulations a reasonable interpretation of section
    163(h)(2)(A) would include the interest here in question and that
    deficiency interest attributable to nonemployee trade or business
    income is not personal interest.       
    Id. at 65
     (Halpern, J.,
    dissenting).   In his view, however, we should have upheld the 9T
    regulation as valid as it was entitled to Chevron deference.         
    Id. at 66
     (Halpern, J., dissenting).
    2.      Ninth Circuit
    The U.S. Court of Appeals for the Ninth Circuit, agreeing
    with the Eighth Circuit, reversed.          Redlark v. Commissioner, 
    141 F.3d at 938, 941
    .    The Court of Appeals for the Ninth Circuit,
    like that of the Eighth Circuit, also treated the 9T regulation
    as a legislative regulation.       
    Id. at 940
    .    The court gave the 9T
    regulation Chevron deference and stated that the issue was
    whether the 9T regulation was a permissible interpretation of
    section 163(h).     
    Id. at 938
    .   The Court of Appeals for the Ninth
    - 116 -
    Circuit acknowledged that it was reasonable that income tax
    deficiencies should properly be considered allocable to their
    business.    
    Id. at 939
    .   The court, however, applied Chevron and,
    like the Eighth Circuit, relied on the Blue Book to conclude that
    the 9T regulation was a permissible construction of the statute.
    
    Id. at 939, 941
    .
    C.     Allen--Fourth Circuit
    The U.S. Court of Appeals for the Fourth Circuit concluded
    that section 163(h) was ambiguous.        Allen v. United States, 
    173 F.3d 533
    , 534 (4th Cir. 1999).      It based this conclusion on “the
    absence of a statutory directive” as to the meaning of “properly
    allocable” and the fact that there were “sharply divergent
    opinions” in Redlark.3     
    Id. at 536
    .    The court applied Chevron
    and accorded the 9T regulation Chevron deference.        
    Id. at 537
    .
    The Court of Appeals for the Fourth Circuit also relied on the
    Blue Book to conclude that the 9T regulation was a permissible
    construction of the statute.     
    Id. at 537-538
    .
    D.     McDonnell--Sixth Circuit
    The U.S. Court of Appeals for the Sixth Circuit, without
    analysis, simply relied on the analysis of the Court of Appeals
    for the Ninth Circuit in Redlark.        McDonnell v. United States,
    
    180 F.3d 721
    , 723 (6th Cir. 1999).
    3
    This suggests that every time a statute fails to define a
    word or term, or any time judges disagree regarding the meaning
    of a word or phrase in a statute, the statute is automatically
    ambiguous.
    - 117 -
    E.     Kikalos--Seventh Circuit
    The U.S. Court of Appeals for the Seventh Circuit
    acknowledged that the 9T regulation is an interpretive
    regulation.    Kikalos v. Commissioner, 
    190 F.3d 791
    , 795 (7th Cir.
    1999), revg. 
    T.C. Memo. 1998-92
     (which relied on our opinion in
    Redlark).   The Court of Appeals for the Seventh Circuit stated
    that “interpretive regulations of this sort, when subject to a
    notice-and-comment procedure, are reviewed deferentially, under
    the criteria articulated in” Chevron and its progeny.     
    Id.
        The
    court noted that the 9T regulation did not go through notice-and-
    comment and that such a regulation might be entitled to no more
    deference than a proposed regulation.4   Id. at 796.   The Court of
    Appeals for the Seventh Circuit, however, left for another day
    what deference a regulation of this sort is due because the
    parties assumed Chevron deference applied.    Id.   Therefore, the
    court accorded the 9T regulation Chevron deference.     Id.
    The Court of Appeals for the Seventh Circuit acknowledged
    that in light of the cases predating the Tax Reform Act of 1986
    (TRA 1986), Pub. L. 99-514, 
    100 Stat. 2085
    , one could argue with
    some force that where an income tax deficiency results from a
    taxpayer’s trade or business the interest accrued on that
    deficiency should be allocable to the trade or business.        
    Id.
     at
    4
    Proposed regulations are generally not afforded any more
    weight than that of the position advanced by the Commissioner on
    brief. Gen. Dynamics Corp. v. Commissioner, 
    108 T.C. 107
    , 120
    (1997); Laglia v. Commissioner, 
    88 T.C. 894
    , 897 (1987).
    - 118 -
    797-798.    Based on the Blue Book and the deference to be accorded
    under Chevron, however, the court upheld the validity of the
    regulation.    
    Id.
    F.   Summary of the Cases
    Thus, all five of the Courts of Appeals accorded the 9T
    regulation Chevron deference.
    III.    Post-Mead Case Law
    In the years that have passed since the U.S. Courts of
    Appeals issued their opinions regarding the 9T regulation,
    principles of law have developed regarding the Chevron doctrine.
    See supra, part I.    The U.S. Court of Appeals for the Fifth
    Circuit, the circuit to which appeal in the instant case lies,
    has stated:    “Mead clarified that Chevron’s expansive conception
    of judicial deference to an administrative agency’s legal
    interpretation applies only when ‘Congress delegated authority to
    the agency generally to make rules carrying the force of law, and
    * * * the agency interpretation claiming deference was
    promulgated in the exercise of that authority.’”    Pool Co. v.
    Cooper, 
    274 F.3d 173
    , 177 n.3 (5th Cir. 2001).    In the absence of
    Chevron deference, pursuant to Mead, the agency’s interpretation
    is accorded respect under Skidmore according to its “power to
    persuade”.    
    Id. at 177
    ; see also Landmark Legal Found. v. IRS,
    
    267 F.3d 1132
    , 1135-1136 (D.C. Cir. 2001) (when Chevron deference
    does not apply, the IRS’s interpretations are entitled to “no
    more than the weight derived from their ‘power to persuade.’”).
    - 119 -
    In light of Mead, Chevron deference is reserved for only
    those agency interpretations reached through notice-and-comment
    or comparable formal administrative procedures.     Ind. Family &
    Soc. Servs. Admin. v. Thompson, 
    286 F.3d 476
    , 480 (7th Cir.
    2002); TeamBank, N.A. v. McClure, 
    279 F.3d 614
    , 619 (8th Cir.
    2002); U.S. Freightways Corp. v. Commissioner, 
    270 F.3d 1137
    ,
    1141 (7th Cir. 2001) (involving the Commissioner of Internal
    Revenue), revg. 
    113 T.C. 329
     (1999).     While the Supreme Court
    left open the possibility that Chevron deference may be
    appropriate in instances similar to notice-and-comment rulemaking
    or formal adjudication, it did not clearly outline these
    instances.5   Matz v. Household Intl. Tax Reduction Inv. Plan, 
    265 F.3d 572
    , 574 (7th Cir. 2001).   Agency interpretations that are
    not the result of such formal administrative procedures are
    entitled to the lesser deference accorded under Skidmore.     Ind.
    Family & Soc. Servs. Admin. v. Thompson, 
    supra at 480
    ; Teambank,
    N.A. v. McClure, 
    supra
     at 619 n.4; U.S. Freightways Corp. v.
    Commissioner, supra at 1141.
    Furthermore, in applying Mead, “mere ambiguity in a statute
    is not evidence of congressional delegation of authority”, agency
    authority is not to be lightly presumed, and courts should not
    5
    “Only when agencies act through ‘adjudication[,] notice-
    and-comment rulemaking, or * * * some other [procedure]
    indicat[ing] comparable congressional intent [whatever that
    means]’ is Chevron deference applicable * * * .” United States
    v. Mead Corp., supra at 240 (Scalia, J., dissenting).
    - 120 -
    presume a delegation of power based solely on the fact that there
    was not an express withholding of such power.     Mich. v. EPA, 
    268 F.3d 1075
    , 1082 & n.2 (D.C. Cir. 2001).
    The fact that a court pre-Mead found the agency’s position
    to be reasonable under the Chevron standard is insufficient;
    after Mead, if Chevron is inapplicable the agency’s position must
    be persuasive.   Matz v. Household Intl. Tax Reduction Inv. Plan,
    supra at 573-575 (applying this rule to the IRS).    It is “plain
    error for [courts] to rely on” Chevron in determining what
    deference to give agency actions without considering Mead.     Am.
    Fedn. of Govt. Employees, AFL-CIO v. Veneman, 
    284 F.3d 125
    , 129
    (D.C. Cir. 2002).   To the extent decisions using a pre-Mead
    analysis differ from the analysis set forth in Mead, Mead
    controls.   Hall v. U.S. EPA, 
    273 F.3d 1146
    , 1156 n.6 (9th Cir.
    2001).
    IV.   Applying Mead to This Case
    I note that “Chevron has had a checkered career in the tax
    arena.”   Cent. Pa. Sav. Association v. Commissioner, 
    104 T.C. 384
    , 391 (1995). “The degree to which courts are bound by agency
    interpretations of law has been like quicksand.    The standard
    seems to have been constantly shifting, steadily sinking, and,
    from the perspective of the intermediate appellate courts,
    frustrating.”    Wolpaw v. Commissioner, 
    47 F.3d 787
    , 790 (6th Cir.
    1995), revg. 
    T.C. Memo. 1993-322
    .
    - 121 -
    We have previously avoided, pre-Mead, the question of
    whether temporary regulations promulgated without notice-and-
    comment procedures are entitled to Chevron deference.
    UnionBanCal Corp. v. Commissioner, 
    113 T.C. 309
    , 316-317 (1999).
    We also have previously questioned, pre-Mead, whether
    Chevron applies to interpretive regulations.     Cent. Pa. Sav.
    Association v. Commissioner, supra at 391 (citing E.I. duPont de
    Nemours & Co. v. Commissioner, 
    41 F.3d 130
     (3d Cir. 1994), affg.
    
    102 T.C. 1
     (1994)).   The question of what deference interpretive
    regulations, including temporary regulations issued without
    notice-and-comment procedures, are entitled needs to be answered
    in light of Mead.
    The first question in the Mead analysis is whether Congress
    delegated authority to the agency to make rules carrying the
    force and effect of law.   United States v. Mead Corp., supra at
    226-227; Pool Co. v. Cooper, 
    supra
     at 177 n.3.    The second
    question is whether the agency invoked that authority.     United
    States v. Mead Corp., supra; Pool Co. v. Cooper, 
    supra.
         In this
    case, however, even assuming that we were to answer the first
    question in the affirmative, we must answer the second question--
    whether the agency invoked the authority delegated--in the
    negative for the reasons set forth below.
    Regulations are either legislative or interpretive in
    character.   Tutor-Saliba Corp. v. Commissioner, 
    115 T.C. 1
    , 7
    (2000).   Interpretive regulations are promulgated under the
    - 122 -
    general authority vested in the Secretary by section 7805,
    whereas legislative regulations are issued pursuant to a specific
    congressional delegation to the Secretary.    Id.; Hefti v.
    Commissioner, 
    97 T.C. 180
    , 189 (1991), affd. 
    983 F.2d 868
     (8th
    Cir. 1993).    “An interpretive regulation may be contrasted to a
    legislative regulation, one which is mandated specifically in the
    statute and has the force and effect of law.”       Matheson v.
    Commissioner, 
    74 T.C. 836
    , 840 n.7 (1980).
    In Redlark v. Commissioner, 
    106 T.C. at 38
    , we stated:
    The regulations involved herein were promulgated
    pursuant to the general authority granted to the
    Secretary of the Treasury by section 7805(a) and not
    pursuant to specific legislative authority, T.D. 8168,
    1988-
    1 C.B. 80
    , 83; they are therefore interpretive.
    The majority opinion in this case agrees with this conclusion,
    and the Commissioner concedes that the 9T regulation is an
    interpretive regulation.    Majority op. p. 40.    As such, even if
    the statute were ambiguous, but see Chief Judge Wells’s dissent,
    and assuming Congress delegated authority to the IRS to make
    rules carrying the force and effect of law in this area, but see
    Judge Swift’s dissent p. 104, it appears that by choosing to
    issue the 9T regulation pursuant to section 7805 the Commissioner
    did not issue the 9T regulation pursuant to a specific
    congressional delegation authority having the force and effect of
    law.    See Tutor-Saliba Corp. v. Commissioner, supra at 7;
    Matheson v. Commissioner, supra at 840 n.7.       Thus, the 9T
    regulation is not entitled to Chevron deference; it is only
    - 123 -
    entitled to Skidmore deference.6   United States v. Mead Corp.,
    supra at 234-235; Pool Co. v. Cooper, 
    supra at 177
    .
    V.   The Majority Opinion
    The majority relies on the pre-Mead opinions of the U.S.
    Courts of Appeals for the Fourth, Sixth, Seventh, Eighth and
    Ninth Circuits to support its conclusion that the 9T regulation
    is valid.   Majority op. pp. 10-13.   This is wrong, as these cases
    were all decided pre-Mead.   Am. Fedn. of Govt. Employees, AFL-CIO
    v. Veneman, supra at 129; Hall v. U.S. EPA, 
    supra
     at 1156 n.6;
    Matz v. Household Intl. Tax Reduction Inv. Plan, supra at 575.
    In judging the validity of the 9T regulation, the majority
    accords an interpretive regulation “considerable weight”, states
    that it will uphold interpretive regulations if they implement
    the congressional mandate in some reasonable manner, applies the
    pre-Mead analysis, and gives the 9T regulation Chevron deference.
    Majority op. pp. 40-41, 43, 51-52.    In light of Mead, this
    analysis is improper.
    Additionally, as is pointed out by Judge Thornton in his
    concurring opinion, the majority relies on the Joint Committee
    6
    It also appears that the 9T regulation is not entitled to
    Chevron deference for another reason: The 9T regulation did not
    go through notice-and-comment, there is no evidence that it went
    through comparable formal administrative procedures, and it
    remains in temporary form 15 years later. Ind. Family & Soc.
    Servs. Admin. v. Thompson, 
    286 F.3d 476
    , 480 (7th Cir. 2002);
    TeamBank, N.A. v. McClure, 
    279 F.3d 614
    , 619 (8th Cir. 2002);
    U.S. Freightways Corp. v. Commissioner, 
    270 F.3d 1137
    , 1141 (7th
    Cir. 2001), revg. 
    113 T.C. 329
     (1999); Kikalos v. Commissioner,
    
    190 F.3d 791
    , 796 (7th Cir. 1999), revg. 
    T.C. Memo. 1998-92
    .
    - 124 -
    staff summary (even though the conference committee chose to
    adopt language less restrictive than the staff summary) and on
    the Blue Book (even though the Blue Book goes far beyond the
    language of the conference committee report to insert ideas from
    the staff summary that it previously suggested to the conference
    committee, but which the conference committee rejected and even
    though the Blue Book was published during the 100th Congress
    while TRA 1986 was enacted during the 99th Congress).   Majority
    op. pp. 17-18, 35.   For the reasons stated in Judge Thornton’s
    concurring opinion, our opinion in Redlark, and Judge Laro’s
    concurring opinion in Redlark, I find this reliance unpersuasive.
    See also Judge Swift’s dissent p. 108.
    The majority acknowledges that section 163(h)(2)(A) does not
    compel the result contained in the 9T regulation but relies on
    the Joint Committee staff summary and Blue Book to conclude the
    9T regulation is a permissible construction.   Majority op. pp.
    47-52.   This would be a slender reed on which to conclude that
    the 9T regulation has the power to persuade and is entitled to
    deference under Skidmore v. Swift & Co., supra, especially in
    light of the acknowledgment that a reasonable interpretation of
    section 163(h)(2)(A) is that income tax deficiency interest
    attributable to nonemployee trade or business income should
    properly be considered allocable to a trade or business and that
    the pre-TRA 1986 case law also supports this conclusion.   Kikalos
    v. Commissioner, 
    190 F.3d at 797-798
    ; Redlark v. Commissioner,
    - 125 -
    
    141 F.3d at 939
    ; Redlark v. Commissioner, 
    106 T.C. at 65
    (Halpern, J., dissenting).
    Deference only sets the framework for judicial analysis; it
    does not displace it.   United States v. Vogel Fertilizer Co., 
    455 U.S. 16
    , 24 (1982); United States v. Cartwright, 
    411 U.S. 546
    ,
    550 (1973); Dresser Indus., Inc. v. Commissioner, 
    911 F.2d 1128
    ,
    1137 (5th Cir. 1990).   The majority relies on Courts of Appeals
    opinions predating United States v. Mead Corp., supra, to analyze
    the validity of section 1.163-9T, Temporary Income Tax Regs.   The
    majority’s analysis is incorrect; therefore, I respectfully
    dissent.
    WELLS, SWIFT, COLVIN, and LARO, JJ., agree with this
    dissenting opinion.
