    141 T.C. No. 12
    UNITED STATES TAX COURT
    YITZCHOK D. RAND AND SHULAMIS KLUGMAN, Petitioners v.
    COMMISSIONER OF INTERNAL REVENUE, Respondent
    Docket No. 2633-11.                           Filed November 18, 2013.
    Ps filed a joint income tax return for 2008 improperly claiming
    three refundable credits: an earned income credit, an additional child
    tax credit, and a recovery rebate credit. As a result, they claimed a
    tax refund of $7,327. The parties agree that the correct tax liability
    was $144. The parties also agree that an accuracy-related penalty
    applies, but they dispute how the penalty should be calculated,
    specifically what should be used as the amount shown as the tax on
    the return. This number affects the amount of the underpayment that
    serves as the base upon which an accuracy-related penalty is
    computed.
    Held: When determining the amount shown as tax on the
    return under I.R.C. sec. 6664(a)(1)(A), the earned income credit,
    additional child tax credit, and recovery rebate credit are taken into
    account but do not reduce the amount shown as tax below zero.

    OPINION
    BUCH, Judge: Respondent determined deficiencies, additions to tax, and
    penalties with respect to petitioners’ joint Federal income tax as follows:
    Addition to tax         Penalty
    Year            Deficiency          sec. 6651(a)(1)       sec. 6662(a)
    2006               $3,540                 $100               $708.00
    2007                3,901                  100                780.20
    2008                8,127                   -0-             1,625.40
    Because the parties have resolved all other issues by stipulation, the only issue for
    the Court to decide is the amount of the penalty under section 6662(a)2 for 2008.
    Determining that amount requires us to first determine the “underpayment of tax
    required to be shown” on petitioners’ 2008 tax return. See sec. 6662(a) (imposing
    20% penalty on specified portions of “an underpayment of tax required to be

    shown on a return”); sec. 6664(a) (defining “underpayment”). This, in turn,
    requires that we determine “the amount shown as the tax” on petitioners’ 2008
    return. See sec. 6664(a)(1)(A).
    Respondent argues that the amount shown as tax on the return is reduced by
    the refundable credits claimed on the return. Under this approach, the amount
    shown as tax on the return is -$7,327. Petitioners argue that the amount shown as
    tax on the return is calculated without regard to refundable credits. Under this
    approach, the amount shown as tax on the return would be $144. The Cardozo
    Tax Clinic argues in its amicus brief (and petitioners argue in the alternative) that
    the amount shown as tax on the return is reduced by the refundable credits but not
    below zero. Under this approach, the amount shown as tax on the return would be
    zero. This last result is correct, because it is the only approach supported by
    principles of statutory construction.
    Background
    Petitioners Rand and Klugman, who were a married couple during 2008,
    timely filed a 2008 joint Federal income tax return on Form 1040, U.S. Individual
    Income Tax Return. On line 7 of their Form 1040 they reported “Wages, salaries,
    tips, etc.” of $17,200. They attached to the Form 1040 a Form 4852, Substitute for
    -4-
    Form W-2,3 that Rand signed and that stated that he had earned $17,200 in
    “Wages, tips, and other compensation”. Petitioners reported business income of
    $1,020 from Rand’s work as a tutor. Lastly, they deducted $72 for one-half of the
    self-employment tax liability imposed by section 1401. In total petitioners
    reported that their adjusted gross income was $18,148.
    This income was reduced to zero by various deductions. Petitioners claimed
    a standard deduction of $10,900 and a deduction of $14,000 resulting from four
    personal exemptions. The result on line 43, where taxable income is reported, was
    zero, which in turn resulted in a tax liability on line 44 also of zero.
    The 2008 Form 1040 has several lines that set forth amounts of tax.
    Starting with a tax of zero on line 44, petitioners reported $144 of self-
    employment tax on line 57. This resulted in a “total tax” on line 61 of $144.
    Credits and Refund
    The total tax of $144 was reduced, below zero, by refundable tax credits.
    Petitioners claimed an earned income credit of $4,824, an additional child tax
    credit of $1,447, and a recovery rebate credit of $1,200. They reported that they
    had two qualifying children for the purpose of calculating the earned income

    credit and the additional child tax credit, and they further reported that each child
    lived with them in the United States during all 12 months of 2008.
    To determine qualification, both the earned income tax credit and the
    additional child tax credit take into account the amount of earned income, and
    petitioners reported earned income of $18,148 on Schedule 8812, Child Tax
    Credit. This amount represents $17,200 of wages and $1,020 of self-employment
    earnings, reduced by $72 for one-half of self-employment taxes. After taking into
    account the refundable credits, petitioners claimed an overpayment of $7,327 on
    line 72 of their return, and on line 73, they requested that the full amount be
    refunded to them.
    On May 4, 2009, the Internal Revenue Service (IRS) refunded the $7,327.
    Agreed Adjustments
    The IRS sent a notice of deficiency to petitioners on December 10, 2010.
    The notice sets forth adjustments to tax and penalties for tax years 2006, 2007, and
    2008, but only the penalty for 2008 remains at issue. The parties have resolved all
    issues for 2006 and 2007 by stipulation.
    -6-
    For 2008 the notice of deficiency contains several adjustments, nearly all of
    which the parties have resolved by stipulation.4 As is relevant to the dispute
    before us, the notice of deficiency determined that petitioners were not entitled to
    the earned income tax credit or the child tax credit; petitioners agreed. Also, the
    notice of deficiency determined that an accuracy-related penalty under section
    6662 applies; the parties agree that a penalty applies “if the Court determines that
    there is ‘an underpayment of tax required to be shown on the return’ within the
    meaning of I.R.C. § 6662(a)”.
    4
    Even after the parties’ stipulations, one issue remains unresolved (in
    addition to the penalty issue addressed in this Opinion). By stipulation, the parties
    agree that petitioners did not have sufficient earned income to qualify for the
    additional child tax credit or the recovery rebate credit. The earned income
    thresholds for claiming the additional child tax credit and the recovery rebate
    credit are $8,500 and $3,000, respectively. See sec. 24(d)(1)(B)(i) (additional
    child tax credit); sec. 6428(b)(2)(A) (recovery rebate credit). Respondent assumes
    that this stipulation eliminated the income reported on line 7, apparently
    predicated on the incorrect notion that all items reported on line 7 are earned
    income. Petitioners make no such assumption; they assume that the $17,200
    remains on line 7.
    We need not resolve the parties’ confusion regarding their own stipulation.
    It is possible to have line 7 income that is not earned income, such as scholarship
    income that is not reported on a Form W-2. See IRS Publ. 596, at 22 (2008). The
    two possible interpretations of their stipulation are (1) petitioners had $17,200 of
    line 7 unearned income, or (2) they had no line 7 income. Under either scenario,
    petitioners’ taxable income is zero, because their income would be fully offset by
    the standard deduction coupled with dependency exemptions.
    -7-
    In addition to the adjustments set forth in the notice of deficiency,
    respondent filed an amendment to his answer in which he asserted that petitioners
    were not entitled to the recovery rebate credit (along with a corresponding
    increase in the penalty under section 6662). Petitioners agreed to this adjustment.
    Thus, after concessions, the sole issue remaining to be decided is whether
    there is an “underpayment” upon which an accuracy-related penalty can be
    computed.
    Positions of the Parties
    The parties submitted the case without trial pursuant to Rule 122.
    Petitioners have conceded that they are liable for the accuracy-related penalty for
    2008 if there is “an underpayment of tax required to be shown on a return” as that
    phrase is used in section 6662(a). It follows from the concession that petitioners
    have waived any defense based on reasonable cause. See sec. 6664(c).
    For the purposes of part II of subchapter A of chapter 68 of the Code, which
    includes section 6662, the term “underpayment” is defined by section 6664(a). It
    consists of four components:
    (1)    the “tax imposed”
    (2)    “the amount shown as the tax by the taxpayer on his return”
    (3)    “amounts not so shown previously assessed (or collected without
    assessment)”, and
    (4)    “the amount of rebates made”.
    -8-
    In their briefs the parties agree that the first component is $144, the third
    component is zero, and the fourth component is zero. Their dispute is about the
    second component: the amount shown as the tax by the taxpayer on the return.
    The IRS contends that the statutory phase “the amount shown as the tax” is
    ambiguous as to whether the amount includes the three refundable credits
    petitioners claimed on their 2008 return. The IRS contends that the Court should
    consult the definition of this phrase in section 1.6664-2(c), Income Tax Regs., and
    that this regulation should be interpreted to require that petitioners’ claims for the
    three credits be included in the computation of the amount shown as tax on their
    return. The IRS contends that its interpretation of the regulation should be
    afforded deference under the principle that an agency’s interpretation of its own
    ambiguous regulation must be afforded deference. See Auer v. Robbins, 
    519 U.S. 452
    , 461 (1997).
    Petitioners contend that the Code unambiguously excludes any credits
    claimed on a return from the computation of the amount of tax shown on the
    return. According to petitioners, the provisions in the Code allowing tax credits
    clearly distinguish between credits and the taxes against which credits are applied.
    For example, section 24(a) provides a “credit against the tax imposed by this
    -9-
    chapter”. To petitioners, this means that the additional child tax credit they
    claimed is not part of the tax shown on their return.
    Petitioners also observe that in defining the amount of tax shown on the
    return for calculating a deficiency, section 6211(b)(4) provides that the difference
    between (1) the refundable credits5 claimed on the return and (2) the amount
    shown as tax on the return (as determined without regard to refundable credits) is
    taken into account as a negative amount of tax. Because Congress did not enact a
    similar provision for the calculation of an underpayment, petitioners contend that
    Congress must have intended that refundable credits be excluded from the tax
    shown on the return in underpayment calculations.
    Petitioners make the following alternative argument: “Even if the
    refundable credits at issue were to be included in the calculation of the amount of
    tax shown by Petitioners on their return, there is no statutory or regulatory basis
    for reducing the amount of tax below zero. Thus, any underpayment would be
    5
    Section 6402(a) provides that the Secretary may credit the amount of an
    “overpayment” against the tax liability of the person making the overpayment and
    must refund any balance to the person. Section 6401(b) provides that if the
    amount of specified credits (including the three credits petitioners claimed on their
    2008 return) exceed the tax imposed by subtitle A (as reduced by other
    nonrefundable credits), the amount of such excess is considered an overpayment.
    - 10 -
    limited to the amount of the credit against Petitioners’ reported self-employment
    tax.” This position was also presented by the Cardozo Tax Clinic.
    The Cardozo Tax Clinic filed an amicus brief contending that the three
    types of credits petitioners claimed are part of the amount shown as tax on the
    return when calculating an underpayment. However, the Clinic contends that the
    tax shown on a return cannot be negative when calculating an underpayment
    because Congress purposefully declined to incorporate a provision like section
    6211(b) in the definition of an underpayment. Thus, the Clinic disagrees with
    petitioners’ primary argument that credits are excluded from the calculation of the
    tax shown on the return, but it agrees with petitioners’ alternative argument.
    Discussion
    The issue to be resolved is the amount of tax shown on the return (within
    the meaning of section 6664(a)(1)(A)) for a 2008 income tax return that reported:
    •      $0 of income tax under section 1,
    •      $144 of self-employment tax under section 1401,
    •      $1,447 of additional child tax credit,
    •      $4,824 of earned income credit, and
    •      $1,200 of recovery rebate credit, resulting in
    •      $7,327 of overpayment, claimed as a refund.
    - 11 -
    The positions taken are: (a) -$7,327, as the IRS argues, (b) $144, as petitioners
    argue, or (c) $0, as the Clinic argues (and as petitioners argue in the alternative).
    We hold that the amount is zero. The result of this conclusion is that, for penalty
    computation purposes, petitioners have an underpayment of $144.
    Operative Provisions
    Section 6662(a) provides the rules for the application of an accuracy-related
    penalty, including a penalty that is predicated on negligence or a substantial
    understatement of income tax. Subsection (a) provides:
    SEC. 6662(a). Imposition of Penalty.--If this section applies to
    any portion of an underpayment of tax required to be shown on a
    return, there shall be added to the tax an amount equal to 20 percent
    of the portion of the underpayment to which this section applies.
    In turn, “underpayment” is defined by section 6664(a), which provides, in relevant
    part:
    SEC. 6664(a). Underpayment.--For purposes of this part, the
    term “underpayment” means the amount by which any tax imposed by
    this title exceeds the excess of--
    (1) the sum of--
    (A) the amount shown as the tax by
    the taxpayer on his return, plus
    - 12 -
    (B) amounts not so shown previously
    assessed (or collected without assessment),
    over
    (2) the amount of rebates made.
    This “part” of the Code includes sections 6662 through 6664.
    Feller v. Commissioner Inapposite
    In this case we are not called upon to address whether the statute is clear on
    its face as to whether “the amount shown as the tax by the taxpayer on his return”
    takes into account the earned income tax credit, the additional child tax credit, or
    the recovery rebate credit. In Feller v. Commissioner, 
    135 T.C. 497
    , 508 (2010),
    we previously held that “Section 6664 is silent and ambiguous with respect to the
    issue before us; i.e., Congress has not directly addressed the meaning of the term
    ‘underpayment’ when a taxpayer has overstated withholding credits.” But in
    Feller the Court addressed the validity of a regulation that interpreted section
    6664.
    In Feller the Court addressed the question of how overstated withholding
    credits under section 31 fit within the definition of an underpayment under section
    6664. As is pertinent here, the Court found the definition of an underpayment to
    be ambiguous, at least insofar as overstated withholding credits are concerned.
    This determination of ambiguity was necessary to the Court’s analysis, because the
    - 13 -
    Secretary had promulgated regulations specifically addressing the treatment of
    withholding credits. One such regulation, section 1.6664-2(c), Income Tax Regs.,
    provides:
    (c) Amount shown as the tax by the taxpayer on his return--(1)
    Defined.--For purposes of paragraph (a) of this section, the amount
    shown as the tax by the taxpayer on his return is the tax liability
    shown by the taxpayer on his return, determined without regard to the
    items listed in paragraphs (b)(1), (2), and (3) of this section, except
    that it is reduced by the excess of--
    (i) The amounts shown by the taxpayer on his return as credits
    for tax withheld under section 31 (relating to tax withheld on wages)
    and section 33 (relating to tax withheld at source on nonresident
    aliens and foreign corporations), as payments of estimated tax, or as
    any other payments made by the taxpayer with respect to a taxable
    year before filing the return for such taxable year, over
    (ii) The amounts actually withheld, actually paid as estimated tax, or
    actually paid with respect to a taxable year before the return is filed for such
    taxable year.
    See sec. 1.6664-2(b)(1), (2), and (3), Income Tax Regs.; see also sec. 1.6664-2(g),
    Example (3), Income Tax Regs. The phrase “items listed in paragraphs (b)(1), (2),
    and (3) of this section” refers to amounts paid by or on behalf of the taxpayer,
    such as estimated taxes and withholding.
    When testing the validity of a regulation, we generally look to the two-part
    test established under Chevron, U.S.A., Inc. v. Natural Res. Def. Council, Inc.,
    
    467 U.S. 837
    (1984). The first prong of that test is “whether Congress has directly
    - 14 -
    spoken to the precise question at issue.” 
    Id. at 842.
    If Congress has not spoken to
    the precise question at issue, then the Court must determine whether the regulation
    “is based on a permissible construction of the statute.” 
    Id. at 843.
    Thus, when
    testing the validity of section 1.6664-2(c), Income Tax Regs., in Feller, the Court
    was first required to determine whether section 6664 has “spoken to the precise
    question at issue.” That question, as noted by the opinion of the Court in Feller,
    was “the meaning of the term ‘underpayment’ when a taxpayer has overstated
    withholding credits.” Feller v. Commissioner, 
    135 T.C. 508
    . In this case, we
    are not addressing withholding credits.
    In contrast to withholding credits, the regulations under section 6664 fail to
    address either of the two questions that are relevant to the current dispute. First,
    they fail to address whether the earned income credit, additional child tax credit,
    and recovery rebate credit are taken into account when calculating the amount
    shown as the tax on the return. One could interpret this regulation as taking into
    account these credits only by relying on the canon expressio unius est exclusio
    alterius, discussed below--i.e., by specifically addressing withheld taxes and
    payments, one could infer that the Secretary intended that no adjustment be made
    for refundable tax credits. Even then, however, the regulations fail to address the
    second question: whether there can be a “negative tax”.
    - 15 -
    Because the Secretary has not promulgated a regulation addressing how the
    refundable credits at issue here should be taken into account, we need not address
    whether the statute leaves room for agency interpretation. It follows that we are
    also not resolving the question of whether the Secretary may promulgate a
    regulation that is inconsistent with this Opinion.6 And the mere fact that we
    devote these pages to interpreting the statute does not, by implication, mean that
    the statute is ambiguous. Whether a statute is ambiguous is determined not only
    from the language of the statute being considered, but also from the “language and
    design of the statute as a whole.” See, e.g., K Mart Corp. v. Cartier, Inc., 
    486 U.S. 281
    , 291 (1988). Thus, in looking beyond the language of section 6664(a)(1)(A)
    as part of our analysis, we are not answering the question of whether the statute is
    ambiguous. We are simply interpreting the statute. And to do so, we turn to
    principles of statutory construction.
    Reading Section 6664(a)(1)(A) in the Light of Section 6211(a)(1)(A)
    Returning to the definition of an underpayment, we note that the Code
    provides the following:
    6
    If the Secretary should promulgate such a regulation, we may be called
    upon to revisit that question, but judicial restraint dictates that we not resolve that
    question now. LTV Corp. v. Commissioner, 
    64 T.C. 589
    , 595 (1975) (“[C]ourts
    will not gratuitously decide complex issues that cannot affect the disposition of the
    case before them.”).
    - 16 -
    SEC. 6664(a). Underpayment.--For purposes of this part, the
    term “underpayment” means the amount by which any tax imposed by
    this title exceeds the excess of--
    (1) the sum of--
    (A) the amount shown as the tax by
    the taxpayer on his return, plus
    (B) amounts not so shown previously
    assessed (or collected without assessment),
    over
    (2) the amount of rebates made.
    A series of canons of statutory construction lead to the conclusion that refundable
    credits must be taken into account when determining the amount shown as the tax
    by the taxpayer but that those credits cannot reduce that amount below zero.
    Where the same words or phrase appear within a text, they are presumed to
    have the same meaning. Atl. Cleaners & Dyers, Inc. v. United States, 
    286 U.S. 427
    , 433 (1932) (“Undoubtedly, there is a natural presumption that identical words
    used in different parts of the same act are intended to have the same meaning.”);
    see also TG Mo. Corp. v. Commissioner, 
    133 T.C. 278
    , 296 (2009). The phrase
    “the amount shown as the tax by the taxpayer” appears three times in the Code.
    - 17 -
    Two of those passages are related: the definition of a deficiency under section
    6211 and the definition of an underpayment under section 6664.7
    Although not explicitly linked today, the definition of a deficiency under
    section 6211 and the definition of an underpayment under section 6664(a) are
    linked by history. As summarized in Feller v. Commissioner, 
    135 T.C. 506
    , in
    1989 several penalty provisions were consolidated into sections 6662 through
    6665. Omnibus Budget Reconciliation Act of 1989, Pub. L. No. 101-239, sec.
    7721(a), 103 Stat. at 2395, 2399. The term “underpayment”, which had been
    defined in section 6653 before the 1989 amendments, was defined in section
    6664(a) after the amendments. Before amendment, “underpayment” was defined
    with an explicit cross-reference to the definition of a deficiency. Specifically,
    section 6653 provided:
    SEC. 6653(c). Definition of Underpayment.--For purposes of
    this section, the term “underpayment” means--
    (1) Income, estate, gift, and certain excise taxes.--In the
    case of a tax to which section 6211 (relating to income, estate,
    gift, and certain excise taxes) is applicable, a deficiency as
    defined in that section * * *
    Thus, at one time, the terms “underpayment” and “deficiency” were coextensive.
    7
    The third passage is section 1314 (amongst the mitigation provisions of
    sections 1311 through 1314), and in that instance, this phrase appears only in
    connection with a cross-reference to section 6211.
    - 18 -
    Although they are linked by history, the fact remains that in 1989 Congress
    uncoupled these terms. And although identical words are presumed to have the
    same meaning, the presumption “‘is not rigid’”. United States v. Cleveland
    Indians Baseball Co., 
    532 U.S. 200
    , 213 (2001) (quoting Atl. Cleaners & 
    Dyers, 286 U.S. at 433
    ). But here, Congress expressly indicated that uncoupling these
    terms was not intended to remove their definitional nexus. Despite detaching the
    definition of an underpayment from the definition of a deficiency, Congress
    informed us that “the bill provides a standard definition of underpayment for all of
    the accuracy-related penalties. This standard definition is intended to simplify and

    different from present law.” H.R. Rept. No. 101-247, at 1394 (1989), 1989
    U.S.C.C.A.N. 1906, 2864. But see H.R. Conf. Rept. No. 101-386, at 654 (1989),
    1989 U.S.C.C.A.N. 3018, 3257. Given that sections 6211(a)(1)(A) and
    6664(a)(1)(A) use the same phrase and that the two provisions are contextually
    and historically related, we turn to section 6211(a)(1)(A) to assist us in
    interpreting the provision before us.
    Credits Reduce Tax Shown on Return
    Before we reach the question of whether the three tax credits at issue can
    reduce the amount shown as tax below zero, we must first decide whether these
    - 19 -
    credits reduce the amount shown as tax to any extent. Although section 6664 is
    silent on this point, section 6211 is instructive.
    Section 6211 expressly excludes certain credits from the amount shown on
    the return as the tax by the taxpayer, which is in turn used to calculate the amount
    of a deficiency. Specifically, section 6211(b) provides:
    SEC. 6211(b). Rules for Application of Subsection (a).--For
    purposes of this section--
    (1) The tax imposed by subtitle A and the tax shown on
    the return shall both be determined without regard to payments
    on account of estimated tax, without regard to the credit under
    section 31, without regard to the credit under section 33, and
    without regard to any credits resulting from the collection of
    amounts assessed under section 6851 or 6852 (relating to
    termination assessments).[8]
    Because the Code specifies that certain credits should be disregarded when
    determining the tax shown on the return, we can infer that other credits should not
    be disregarded. Under the canon expressio unius est exclusio alterius, if a statute
    provides specific exceptions to a general rule, we may infer that Congress
    intended to exclude any further exceptions. Leatherman v. Tarrant Cnty.

    This section was also present in substantially the same form before the
    1989 amendments that removed the express cross-reference from the definition of
    an underpayment to the definition of a deficiency.

    589 F.2d 123
    (3d Cir. 1978). This is not a rigid rule and will not
    apply if the result “is contrary to all other textual and contextual evidence of
    congressional intent.” Burns v. United States, 
    501 U.S. 129
    , 136 (1991); see also
    Neuberger v. Commissioner, 
    311 U.S. 83
    , 88 (1940). In this instance we see no
    evidence of a contrary congressional intent. Whether we review the context
    surrounding the definition of an underpayment under section 6664 or the
    definition of a deficiency under section 6211, the statute is silent as to the
    treatment of the refundable tax credits at issue here. In the absence of anything
    showing a contrary congressional intent, the canon expressio unius est exclusio
    alterius applies. Because Congress expressly chose to disregard certain credits
    when determining the amount shown as the tax by the taxpayer on his return when
    calculating a deficiency, it follows that other credits should be taken into account
    to reduce the amount so shown. Because the phrase “the amount shown as the tax
    by the taxpayer” appears in both sections, 6211 and 6664, we likewise conclude
    that the amount shown as the tax by the taxpayer on his return when calculating an
    underpayment should be reduced by refundable credits.
    Although not specifically addressed in our prior opinions, this holding is
    consistent with many previous opinions of this Court, including Feller, where the
    - 21 -
    claiming of a credit to which a taxpayer was not entitled resulted in the imposition
    of a penalty. Most credits are identified in the Code as a “credit against the tax
    imposed”.9 Petitioners attach special meaning to the phrase “credit against the
    tax” and infer from those words that a credit against the tax is a payment and not
    part of the tax itself. Whether a particular tax credit is a refundable credit or not,
    the Code uses this same phrase “credit against the tax”. Compare section 32(a)(1)
    (earned income credit applied as a “credit against the tax imposed”) with section
    38(a) (general business credit applied as a “credit against the tax imposed”). And
    we have imposed penalties on disallowed credits against the tax under many
    provisions.10 In doing so, we necessarily reduced the amount shown as tax by the
    9
    See sec. 21 (expenses for household and dependent care services necessary
    for gainful employment); sec. 22 (credit for the elderly and the permanently and
    totally disabled); sec. 23 (adoption expenses); sec. 24 (child tax credit); sec. 25
    (interest on certain home mortgages); sec. 25A (hope and lifetime learning
    credits); sec. 25B (elective deferrals and IRA contributions by certain individuals);
    sec. 25C (nonbusiness energy property); sec. 25D (residential energy efficient
    property); sec. 27 (taxes of foreign countries and possessions of the United States;
    possession tax credit); sec. 30 (credit for qualified electric vehicles); sec. 30A
    (Puerto Rico economic activity credit); sec. 30B (alternative motor vehicle credit);
    sec. 30C (alternative fuel vehicle refueling property credit); sec. 38 (general
    business credit); sec. 53 (credit for prior year minimum tax liability); and sec. 54
    (credit to holders of clean renewable energy bonds). In using that same phrase, the
    general business credit under section 38 brings along with it more than 30 other
    credits that must also be considered a “credit against the tax”. See sec. 38(b).

    reported credit against the tax. Nothing in the Code suggested that such credits
    should have been removed from the computation, and nothing in the Code
    suggests that we should do so now.
    No Negative Tax
    Having concluded that credits can reduce the amount shown as tax on the
    return, we must next address the Clinic’s argument that the earned income credit,
    additional child tax credit, and recovery rebate credit cannot reduce the amount
    shown as the tax on the return below zero. We again turn to canons of statutory
    construction.
    Section 6664(a) is silent on the issue of whether the amount shown as the
    tax on the return can be negative. But as noted previously, where the same phrase
    appears multiple times in the same statutory scheme, we can look to those other
    appearances to help discern the meaning. Conveniently, section 6211 directly
    addresses the question of a negative tax.

    Section 6211(b)(4) provides:
    SEC. 6211(b). Rules for Application of Subsection (a).--For
    purposes of this section--
    *      *       *     *       *      *         *
    (4) For purposes of subsection (a)--
    (A) any excess of the sum of the credits
    allowable under sections 24(d), 32, 34, 35, 36,
    53(e), and 6428 over the tax imposed by subtitle A
    (determined without regard to such credits), and
    (B) any excess of the sum of such credits as
    shown by the taxpayer on his return over the
    amount shown as the tax by the taxpayer on such
    return (determined without regard to such credits),
    shall be taken into account as negative amounts of tax.
    More simply stated, any excess of the refundable credits claimed as compared to
    the amount to which the taxpayer was entitled is treated as a negative tax.
    We can infer from this provision that the specified refundable credits would
    not be considered a negative tax but for this provision. In this instance, the
    surplusage canon leads us to conclude that excess credits are not otherwise a
    negative tax. Under the surplusage canon we are to give effect to every provision
    Congress has enacted. United States v. Menasche, 
    348 U.S. 528
    , 538-539 (1955)
    (“‘The cardinal principle of statutory construction is to save and not to destroy.’
    Labor Board v. Jones & Laughlin Steel Corp., 
    301 U.S. 1
    , 30 (1937). It is our
    - 24 -
    duty ‘to give effect, if possible, to every clause and word of a statute,’ Inhabitants
    of Montclair Tp. v. Ramsdell, 
    107 U.S. 147
    , 152 (1883), rather than to emasculate
    an entire section”.); see also Tucker v. Commissioner, 
    135 T.C. 114
    , 154 (2010)
    (“[W]e decline to read words out of the statute; rather, we attempt to give meaning
    to every word that Congress enacted[.]”). If, as respondent suggests, these credits
    are considered a negative tax, then section 6211(b)(4) would be mere surplusage;
    it would be wholly unnecessary. To give section 6211(b)(4) any meaning, we
    must assume that, in determining the amount shown as the tax, the specified
    credits would not be considered a negative tax but for that provision. We then use
    this conclusion to inform our views on the use of the word “underpayment” in
    section 6664.
    Based on the negative tax provision of section 6211(b)(4), we conclude that
    these credits do not yield a negative tax for purposes of defining an underpayment
    under section 6664(a)(1)(A). We return to our premise that, because section
    6664(a)(1)(A) uses the same phrase “the amount shown as the tax by the taxpayer”
    as section 6211(a), we should interpret it consistently with section 6211. And we
    have concluded that, but for section 6211(b)(4), the specified refundable credits
    would not yield a negative tax for the amount shown as the tax by the taxpayer.
    Thus, we must likewise conclude that these refundable credits would not yield a
    - 25 -
    negative tax for the amount shown as the tax under section 6664 unless there is a
    counterpart to section 6211(b)(4). In turning to section 6664, we find no
    counterpart to section 6211(b)(4). Accordingly, excess earned income credits,
    additional child tax credits, and recovery rebate credits do not result in a negative
    tax for the amount shown as the tax by the taxpayer on his return.
    We note that our conclusion breaks the historical link between the
    definitions of a deficiency and an underpayment; however, it was Congress that
    made that break. As we previously noted, the definition of an underpayment was
    linked to the definition of a deficiency until 1989. In 1988 Congress amended
    section 6211(b)(4) to specifically provide that certain refundable credits could be
    taken into account as negative amounts of tax. Technical and Miscellaneous
    Revenue Act of 1988, Pub. L. No. 100-647, sec. 1015(r)(2), 102 Stat. at 3572.11
    Because this occurred when the definition of an underpayment was linked to the
    11
    Of the credits at issue here, only the earned income credit was included in
    section 6211(b)(4) in 1988. In 1998 Congress added the additional child tax credit
    to the Code, and in 2000 it incorporated the credit in the negative tax provision of
    section 6211(b)(4). Consolidated Appropriations Act, 2001, Pub. L. No. 106-554,
    sec. 1(a)(7), 114 Stat. at 2763 (amending sec. 6211(b)(4)); Taxpayer Relief Act of
    1997, Pub. L. No. 105-34, sec. 101(a), 111 Stat. at 788 (adding sec. 24). In 2008
    Congress added the rebate recovery credit to the Code and incorporated the credit
    in the negative tax provision of section 6211(b)(4). Economic Stimulus Act of
    2008, Pub. L. No. 110-185, sec. 101(b)(1), 122 Stat. at 615 ( amending sec.

    - 26 -
    definition of a deficiency, it meant that those credits would be considered a
    negative tax for the definition of an underpayment as well. We previously noted
    that Congress expressed the view that uncoupling the link between sections
    6664(a)(1)(A) and 6211(a)(1)(A) was not intended to “substantively” alter the
    definition of an underpayment. H.R. Rept. No. 101-247, supra at 1394, 1989
    U.S.C.C.A.N. at 2864. But as was noted in Feller, the legislative history states
    that “the new definition was intended to ‘simplify and coordinate’ diverse
    ‘underpayment’ definitions under former law. And in fact the new
    ‘underpayment’ definition in section 6664(a) differs in various ways from the old
    ‘underpayment’ definitions which it replaced.” Feller v. 
    Commissioner, 135 T.C. at 514-515
    (Thornton, J., concurring) (quoting H.R. Rept. No. 101-247, supra at
    1394, 1989 U.S.C.C.A.N. at 2864). One of those differences is that Congress did
    not include a counterpart to section 6211(b)(4) in section 6664(a). If this is not
    what Congress intended, it is not for the Court to reform the statute. Verito v.
    Commissioner, 
    43 T.C. 429
    , 443 (1965) (“We were not given the responsibility of
    writing statutes, but we do have the responsibility of interpreting them as we find
    them.”).
    Moreover, Congress has made it clear in analogous circumstances when it
    intended refundable credits to be taken into account. We have already shown how
    - 27 -
    Congress addressed a “negative tax” in section 6211. Likewise, in the preparer
    penalty of section 6694, Congress made it clear that refunded amounts like the
    refundable credits at issue here should be taken into account for purposes of
    determining an underpayment.
    Section 6694 imposes a penalty on a tax return preparer who prepares a
    return with an “unreasonable position” as that term is defined in section
    6694(a)(2). For the penalty to apply, there must be an “understatement of
    liability”. Sec. 6694(a)(1)(A). Congress, however, made it clear that an
    understatement of liability includes a situations where a return has overstated
    credits that yield a refund. Specifically, section 6694(e) provides in relevant part:
    SEC. 6694(e). Understatement of Liability Defined.--For
    purposes of this section, the term “understatement of liability” means
    any understatement of the net amount payable with respect to any tax
    imposed by this title or any overstatement of the net amount
    creditable or refundable with respect to any such tax. * * *
    By including the phrase “or any overstatement of the net amount creditable or
    refundable”, Congress explicitly defined “understatement” for preparer penalty
    purposes to include refundable credits. Congress could have similarly taken such
    credits into account under the definition of an underpayment under section
    6664(a), but it did not.
    - 28 -
    Rule of Lenity
    Beyond the previously discussed canons of statutory construction on which
    we rely, our Opinion is further supported by another canon: the rule of lenity.
    The rule of lenity is an “ancient maxim” that “is perhaps not much less old
    than construction itself. It is founded on the tenderness of the law for the rights of
    individuals; and on the plain principle that the power of punishment is vested in
    the legislative, not in the judicial department. It is the legislature, not the Court,
    which is to define a crime, and ordain its punishment.” United States v.
    Wiltberger, 
    18 U.S. 76
    , 95 (1820). Thus, under the rule of lenity statutes that
    impose a penalty are to be construed in favor of the more lenient punishment.
    Black’s Law Dictionary 1449 (9th ed. 2009). And although often considered in
    the criminal context, the rule of lenity has been applied in the civil context and
    specifically with regard to civil tax penalties.
    In Commissioner v. Acker, 
    361 U.S. 87
    (1959), the IRS sought to impose
    two penalties on a taxpayer as a result of the taxpayer’s failure to file a declaration
    of estimated income tax. One penalty was for a failure to file the declaration. The
    other, however, was for a “substantial underestimate of estimated tax”. The latter
    penalty came about because, by regulation, the failure to file a declaration of
    estimated tax was deemed to be an estimate of zero. In rejecting the latter penalty,
    - 29 -
    the Supreme Court stated: “We are here concerned with a taxing Act which
    imposes a penalty. The law is settled that ‘penal statutes are to be construed
    strictly,’ and that one ‘is not to be subjected to a penalty unless the words of the
    statute plainly impose it’.” 
    Id. at 91
    (fn. ref. omitted) (quoting FCC v. Am.
    Broadcasting Co., 
    347 U.S. 284
    , 296 (1954), and Keppel v. Tiffin Sav. Bank, 
    197 U.S. 356
    , 362 (1905)).
    Here, the words of the relevant statutes do not plainly impose a penalty on
    refunds resulting from overstated earned income credits, additional child tax
    credits, or recovery rebate credits. Because the penalty is not plainly imposed on
    the refundable portion of the credits, the rule of lenity further confirms what we
    have already concluded: that section 6662 does not impose a penalty on the
    refundable portion of erroneously claimed earned income credits, additional child
    tax credits, and recovery rebate credits.
    Additional Issues Raised by Respondent
    We have concluded that the earned income credit, additional child tax
    credit, and recovery rebate credit can be taken into account to reduce the amount
    shown as tax on the return, but not below zero. We turn to two additional points
    raised by respondent.
    - 30 -
    Auer Deference
    Respondent urges us to apply Auer deference to his interpretation on brief
    of the phrase “the amount shown as the tax by the taxpayer on his return”. See
    Auer, 
    519 U.S. 452
    . When applying Auer deference, a court defers to an agency’s
    interpretation of its own ambiguous regulation, even where that interpretation
    appears on brief. Chase Bank USA, N.A. v. McCoy, 562 U.S. __, __, 
    131 S. Ct. 871
    , 880 (2011). Judicial deference need not give way to judicial abdication. The
    regulations are silent on the issue before us, and respondent’s position on brief is
    at least arguably inconsistent with the statute.
    Although we do not in this instance defer to respondent’s interpretation on
    brief, we note that our interpretation of the statute is not inconsistent with the
    regulation. To the extent the regulation implies that refundable credits should be
    taken into account in determining the amount shown as the tax, we have done so.
    But, consistent with the statutory scheme, we have done so only to the extent that
    it does not give rise to a negative tax. On this, the regulation is silent.
    Gap in the Penalty Regime
    Respondent also asserts that if his position is not adopted there would be a
    gap in the penalty regime. Respondent’s point is not well taken for at least three
    reasons.
    - 31 -
    First, to the extent respondent’s claim is that a claim of excess refundable
    credits could not be penalized under our holding, respondent is mistaken. To the
    extent the credits reduce the amount of tax shown on the return, the disallowance
    of those credits will result in an increased underpayment upon which a section
    6662 accuracy-related penalty could be imposed. More simply stated, the portion
    of a disallowed credit that reduced a tax liability may be subject to an accuracy-
    related penalty.
    Second, to the extent an improperly claimed credit resulted in a refund, it
    may be subject to a penalty under section 6676. In 2007 Congress added section
    6676, which imposes a 20% penalty on an erroneous claim for refund. Small
    Business and Work Opportunity Tax Act of 2007, Pub. L. No. 110-28, sec.
    8247(a), 121 Stat. at 204. An erroneous claim for refund is any claim for refund of
    an “excessive amount”, which is defined as “the amount by which the amount of
    the claim for refund or credit for any taxable year exceeds the amount of such
    claim allowable”. Sec. 6676(b). Such a penalty might have applied here, if
    respondent had asserted it. Thus, there is no gap in the penalty regime. To the
    extent an erroneously claimed credit reduces a tax liability, it may be subject to an
    accuracy-related penalty under section 6662; to the extent that credit generates a
    refund, it may be subject to a penalty under section 6676.
    - 32 -
    And third, respondent is incorrect that there would be a gap in the penalty
    regime insofar as an erroneously claimed earned income tax credit is concerned.
    In 1997 Congress carved out a separate sanction for taxpayers who improperly
    claim the earned income tax credit. See sec. 32(k) (added by the Taxpayer Relief
    Act of 1997, Pub. L. No. 105-34, sec. 1085, 111 Stat. at 955). Specifically, section
    32(k) provides that a false claim to the earned income credit in one tax year results
    in the denial of the earned income credit in the next two tax years “[If] there was a
    final determination that the taxpayer’s claim of credit * * * was due to reckless or
    intentional disregard of rules and regulations”.12 And it appears that Congress
    intended that the two-year bar be in lieu of any other monetary sanctions. For
    example, the penalty under section 6676 for an erroneous claim for refund
    specifically excludes a claim for refund relating to an erroneous earned income
    credit.
    Conclusion
    In the case of an underpayment due to negligence or a substantial
    understatement of income tax, among other things, section 6662 imposes an
    accuracy-related penalty on the underpayment. Section 6664(a) defines the term
    12
    The period of disallowance is 10 years if the claim of credit is due to
    fraud.
    - 33 -
    “underpayment” in part by reference to the amount shown as the tax by the
    taxpayer on his return. The earned income credit, additional child tax credit, and
    recovery rebate credit all reduce the amount shown as the tax by the taxpayer on
    his return, but not below zero.
    To reflect the foregoing and concessions,
    Decision will be entered
    under Rule 155.

    GUSTAFSON, J., dissenting: The Commissioner argues that petitioners are
    liable under section 6662(a) for an accuracy-related penalty of about $1,494,
    because of an “underpayment” of their tax. Colloquially, one could certainly say
    that petitioners “underpaid” their 2008 income tax by claiming refundable credits
    to which they were not entitled. However, as the majority opinion explains, in a
    case like this one an “underpayment” is defined in section 6664(a)(1)(A), and it
    exists only where the tax “imposed” exceeds the tax “shown” (i.e., “the amount
    shown as the tax by the taxpayer on his return”). The majority opinion corrects
    one significant fallacy in the Commissioner’s reckoning (i.e., the Commissioner’s
    erroneous assumption that there can be a “negative amount of tax” for purposes of
    computing the underpayment to be penalized); but the majority still holds
    petitioners liable for a lesser penalty (about $29) that, though modest in amount,
    contradicts an important principle: The IRS has no authority to impose, and the
    courts have no authority to sustain, a penalty that Congress did not enact.1

    extreme: The outcome in Feller was supported by a regulation, i.e., 26 C.F.R.
    section 1.6664-2(c)(1), Income Tax Regs. (which the majority held valid, over my
    dissent); but in this case there is no equivalent regulation to define “tax shown” in
    such a way as to support the imposition of the penalty. This absence of a
    regulation makes all the more appropriate the invocation of the rule of lenity

    I. Introduction
    For 2008 petitioners filed a Form 1040, “U.S. Individual Income Tax
    Return”, on which they reported income and tax but also claimed refundable
    credits (to which they were not entitled). As a result, petitioners incorrectly
    reported no balance due but rather claimed an overpayment and a refund to which
    they were not entitled.
    In particular, Form 1040 for 2008 required petitioners to report “Tax” on
    line 44, “Alternative minimum tax” on line 45, and the total of those on line 46.
    The form called for various non-refundable credit amounts not at issue here on
    lines 47-55, “Self-employment tax” on line 57, and “total tax” on line 61. As their
    “total tax”, petitioners reported $144. (I submit that this $144 amount is “the
    amount shown as the tax by the taxpayer on his return” for purposes of section
    6664(a)(1)(A)).
    Thereafter, in the section of Form 1040 entitled “Payments”, petitioners
    claimed an “Earned income credit” (line 64a), an “Additional child tax credit”
    (line 66), and a “Recovery rebate credit” (line 70), to which they were not actually

    (discussed below) to construe the penalty statute narrowly. Cf. Babbitt v. Sweet
    Home Ch. of Comtys. for a Great Or., 
    515 U.S. 687
    , 704 n.18 (1995) (“We have
    applied the rule of lenity * * * where no regulation was present”).
    - 36 -
    entitled. They reported “total payments” of $7,471 (consisting solely of those
    excessive claimed credits) and therefore reported an “amount you overpaid” of
    $7,327 on line 72, and they requested on line 73 that it all be “refunded to you”.
    The IRS determined against petitioners an accuracy-related penalty pursuant
    to section 6662(a). That penalty depends on (among other things) “the amount
    shown as the tax by the taxpayer on his return”. Rather than using the “total tax”
    of $144 that petitioners reported on line 61 of their return as the tax shown, the
    IRS used negative $7,327 (i.e., the erroneous overpayment petitioners claimed on
    line 72), and the majority uses zero (an amount calculated by subtracting the
    excess credits from the tax reported, but not going below zero). Neither of these
    approaches is warranted by the statute.
    II. The governing law
    Under our Constitution, it is Congress that enacts laws. See U.S. Const.
    art. I, sec. 7, cl. 1. The first enumerated power given to Congress (and not to the
    Executive or the courts) is the “Power To lay and collect Taxes, Duties, Imposts
    - 37 -
    and Excises”. 
    Id., sec. 8,
    cl. 1.2 As the Supreme Court observed in Whitman v.
    Am. Trucking Ass’ns, 
    531 U.S. 457
    , 472 (2001):
    Article I, § 1, of the Constitution vests “[a]ll legislative Powers herein
    granted * * * in a Congress of the United States.” This text permits
    no delegation of those powers * * *.
    Only the legislature can legislate. Only Congress can enact tax laws.
    Section 6664(a) defines the “underpayment” to which the accuracy-related
    penalty of section 6662 applies. Section 6664(a) provides as follows:
    SEC. 6664(a). Underpayment.--For purposes of this part, the
    term “underpayment” means the amount by which any tax imposed by
    this title exceeds the excess of--
    (1) the sum of--
    (A) the amount shown as the tax by the taxpayer
    on his return, plus
    2
    Article I, Section 7, Clause 1 of the Constitution includes an additional
    democratic provision particular to tax law: “All bills for raising revenue shall
    originate in the House of Representatives”--i.e., the house that (in James
    Madison’s words) “speak[s] the known and determined sense of a majority of the
    people”. See The Federalist No. 58 (James Madison) (the two houses have “equal
    authority * * * on all legislative subjects, except the originating of money bills”,
    which authority is conferred on “the House [of Representatives], composed of the
    greater number of members, * * * and speaking the known and determined sense
    of a majority of the people”). Article I, Section 9, Clause 4 of the Constitution
    originally prohibited “direct” taxes; and when the Constitution was amended to
    curtail that prohibition, the Sixteenth Amendment provided (echoing Article I,
    section 8) that “[t]he Congress shall have power to lay and collect taxes on
    incomes”.
    - 38 -
    (B) amounts not so shown previously assessed (or
    collected without assessment), over
    (2) the amount of rebates made.
    For purposes of paragraph (2), the term “rebate” means so much of an
    abatement, credit, refund, or other repayment, as was made on the
    ground that the tax imposed was less than the excess of the amount
    specified in paragraph (1) over the rebates previously made.
    In simplified terms, the “underpayment” is the excess of one’s actual liability over
    his reported liability--i.e., tax “imposed” minus tax “shown” equals
    “underpayment”.
    By statute Congress has authorized the Secretary of the Treasury to
    prescribe “regulations for the enforcement of” the Internal Revenue Code, see
    sec. 7805(a); and where such authorized regulations interpret a statute, the courts
    defer to that interpretation, see Chevron, U.S.A. Inc. v. Natural Res. Def. Council,
    Inc., 
    467 U.S. 837
    , 843-845 (1984). Notably, in Feller v. Commissioner, 
    135 T.C. 497
    (2010), a majority of this Court deferred to such a regulation--i.e., 26 C.F.R.
    section 1.6664-2(c)(1), Income Tax Regs.--to define tax “shown” (and thereby to
    define “underpayment”) in a manner not suggested in the statute.3 However, the
    3
    See note 1, above. An analogous regulation defines “tax shown” for
    purposes of avoiding the penalty for failure to pay estimated tax: One can pay
    “100 percent of the tax shown on the return of the individual for the preceding
    taxable year.” Sec. 6654(d)(1)(B)(ii) (emphasis added). The statute is silent about
    (continued...)
    - 39 -
    regulations that define an “underpayment” include no provision to the effect that
    excess refundable credits somehow reduce tax “shown”.
    There is no other law governing the issue in this case--unless we invent it.
    III.   Discussion
    Without doubt, Congress could impose a penalty for claiming refundable
    credits to which one is not entitled. The question we face is whether in fact
    Congress did so in section 6662(a) when it imposed the accuracy-related penalty
    on “underpayments”, defined in section 6664(a)(1)(A) as “tax imposed” minus
    “amount shown”, or whether instead the IRS and the majority go beyond the
    statute in determining a penalty liability for improperly claimed refundable credits.
    A.    The Commissioner’s position and the majority opinion are at odds
    with the plain meaning of “the amount shown as the tax by the
    taxpayer on his return”.
    The term at issue is “the amount [1] shown [2] as the tax [3] by the taxpayer
    [4] on his return”. Sec. 6664(a)(1)(A). Under section 6664(a) this amount is
    subtracted from “tax imposed” (i.e., the actual tax liability) to yield the
    “underpayment”. The plain meaning of this term could hardly be clearer:
    3
    (...continued)
    credits, but the regulations make it appear that “tax shown” means tax minus
    refundable credits (but not withholding credits or payments of estimated tax). See
    26 C.F.R. sec. 1.6654-2(a)(1)(i), (b)(1)(iii), (b)(2)(i). But again, there is no such
    regulation pertinent to the accuracy-related penalty of section 6662.
    - 40 -
    In the first place, the amount in section 6664(a)(1)(A) is an amount
    “shown”. It is therefore an amount that is visible. The plain language steers us
    away from an amount that would need to be determined by investigation or
    correction and points us simply to what is “shown”--in this case, the $144 amount
    shown by petitioners as “total tax” on line 61. However, both the Commissioner
    and the majority opinion substitute for this amount “shown” a lesser amount
    computed by subtracting excess credits. Neither of the resulting numbers (i.e.,
    neither the Commissioner’s proposed negative $7,327 nor the majority’s zero
    amount) is shown anywhere on petitioners’ 2008 return as an amount of “tax”, so
    the Commissioner and the majority look to an amount that is not shown as tax and
    thereby ignore the plain language of the statute that describes an amount “shown”.
    Second, the amount in section 6664(a)(1)(A) is “tax”. Of course, the Code
    also has provisions about other kinds of amounts--e.g., of income, deductions,
    costs, basis, exclusions, credits, payments, penalties, and so on--but section
    6664(a)(1)(A) refers to an amount of “tax”, a term not at all interchangeable with
    those other kinds of amounts. But both the Commissioner and the majority
    compute an amount that consists of tax reduced by excess refundable credits.
    However, the plain meaning of the statutory language restricts us to “tax” that is
    - 41 -
    shown on the return, and the statutory language gives no warrant for injecting
    excess credits into the equation.
    Third, section 6664(a)(1)(A) looks to an amount shown “by the taxpayer”.
    Of course, the Code authorizes the IRS to make its own determinations of amounts
    relevant to tax liabilities; but plainly section 6664(a)(1)(A) describes an amount
    shown “by the taxpayer”. The Commissioner and the majority correct the amount
    shown “by the taxpayer[s]” on their return, $144, and replace it with other
    numbers that they determine. Their methods thus wander from the plain language
    of section 6664(a)(1)(A), which looks to an amount shown “by the taxpayer”.
    Fourth, the amount in section 6664(a)(1)(A) is an amount shown as tax “on
    his return”. The Commissioner designed Form 1040 and designated certain items
    and not others as “tax”. Petitioners were required to use Form 1040 and did so.
    By using an amount other than the $144 that petitioners reported as “total tax” on
    the prescribed return, the Commissioner and the majority contradict the plain
    meaning of the statutory description of an amount of tax “on the return”.
    B.     The Form 1040 “return” has never “shown as the tax” an amount
    reduced by refundable credits.
    The critical term in section 6664(a)(1)(A) is the “amount shown as the tax
    on the return”. (Emphasis added.) Section 6011(a) authorizes the IRS to prescribe
    - 42 -
    returns and requires taxpayers to use them. In 26 C.F.R. section 1.6012-1(a)(6),
    Income Tax Regs., the IRS has prescribed Form 1040. It is therefore appropriate
    to accord great weight to the manner in which tax and refundable credits are
    characterized on Form 1040.
    In fact, Form 1040 calls for a computation of “total tax” (without reduction
    by refundable credits) and only then calls for the refundable credits to be reported
    as “payments”, consistent with the Code.4 Form 1040 was so arranged when
    refundable credits were first allowed in 1975;5 and when Congress enacted the
    current penalty regime in 1989 (and employed the “shown * * * on his return”
    definition), the Form 1040 return most recently in use--i.e., the Form 1040 for
    4
    The portion of a refundable credit that exceeds the tax liability is an
    “overpayment”, see secs. 37, 6401(b)(1); an overpayment is by definition a “part
    of the amount of the payment”, sec. 6401(a) (emphasis added); and the refundable
    credit is therefore treated in the Code as a payment. By contrast, nonrefundable
    credits are limited to and can never exceed the amount of the tax liability, see
    sec. 26(a), and thus never reduce the liability below zero.
    5
    When the first refundable credit (the earned income tax credit) appeared on
    the Form 1040 for 1975, “Tax” was computed on line 16a and was reduced by
    certain credits before the addition of “Other taxes” (line 19) to yield a “Total” (line
    20). From that were subtracted withholding, estimated payments, the EITC (line
    21c), and other payments to yield (on line 23 or line 24) either a “BALANCE
    DUE IRS” (not a “tax”) or an “amount OVERPAID”. That is, the 1975 Form
    1040 reflected that credit amounts like these are in the nature of payments, not tax.
    The Form 1040 for 2008 was similar in all material respects to the Form 1040 for
    1975.
    - 43 -
    1988--reflected this same arrangement.6 The IRS has always constructed the
    Form 1040 return in such a way that “total” tax is figured first and then refundable
    credits are characterized as “payments” of that tax. The IRS has never prescribed
    an individual income tax return on which there was “shown as the tax” an amount
    that had already been reduced by refundable credits.
    I do not suggest that IRS forms and instructions are generally precedential.
    Cf. Casa De La Jolla Park, Inc. v. Commissioner, 
    94 T.C. 384
    , 396 (1990) (“The
    sources of authoritative law in the tax field are the statute and regulations and not
    government publications”). But here the statutory definition of “underpayment”
    6
    On the Form 1040 for 1988, the “Tax Computation” section (consisting of
    lines 32 through 40) included, after the computation of taxable income, a line 38
    on which one was to “Enter tax”, a line 39 for “Additional taxes”, and a line 40
    that totaled lines 38 and 39. The next section, entitled “Credits” (lines 41 through
    47), consisted not of refundable credits in the nature of payments against the tax
    liability but instead credits (such as the child care credit and the foreign tax credit)
    that are taken into account in figuring the tax liability. Thereafter, a section of
    “Other Taxes” (lines 48 through 53) included, for example, the self-employment
    tax and the alternative minimum tax; and it ended with line 53, which read: “Add
    lines 47 through 52. This is your total tax” (bold in original). Only after this
    “total tax” on line 53 did the 1988 return include, in the section of the return
    entitled “Payments”, an entry (at line 56) for “Earned income credit”, which was
    one of the items that yielded “total payments” on line 61. The net amount due
    after these “total payments” was not referred to as tax, but either as an “amount
    OVERPAID” (line 62) or as an “AMOUNT YOU OWE” (line 65). This is what in
    fact appeared on a “return” at the time Congress defined a taxpayer’s
    underpayment as “tax imposed” minus tax “shown * * * on his return”. The
    Form 1040 for 2008 was similar in all material respects to the Form 1040 for
    1988.
    - 44 -
    utterly depends on and incorporates the “return”. By definition, petitioners cannot
    owe the penalty unless they under-reported “the amount shown as the tax * * * on
    [their] return” (emphasis added)--but the parties and the majority admit that the
    “total tax” of $144 that they did show on their return was correct. Everyone
    agrees that the tax imposed, $144, was the “total tax” amount shown on the return.
    Given the wording of section 6664(a)(1)(A), one cannot ignore petitioners’ actual
    “return” in finding an underpayment and imposing the accuracy-related penalty.
    C.     The definition of “deficiency” in section 6211 does not alter the
    definition of “underpayment” in section 6664(a).
    To interpret the “underpayment” definition in section 6664(a), the majority
    looks to the “deficiency” definition in section 6211(b)(1), which employs similar
    phrases, but the majority thereby draws incorrect inferences. In defining a tax
    “deficiency”, section 6211(b)(1) provides that “[t]he tax imposed * * * and the tax
    shown * * * shall both be determined without regard to” certain credits but does
    not provide for disregarding the refundable credits at issue here. The majority
    therefore invokes the canon expressio unius est exclusio alterius and infers that, as
    a general rule, “tax shown” must therefore include all those credits (else no
    exclusion of any would have been necessary). And the majority opinion goes on
    to note that no such exclusions are provided in section 6664(a) defining
    - 45 -
    “underpayment”, and therefore “underpayment” must be determined with regard to
    these unmentioned credits. That is, the opinion effectively holds that “tax
    imposed” and “tax shown” must generally mean tax after (among other things) the
    refundable credits at issue here. For two reasons this argument is untenable.
    First, if not only tax “shown” but also “tax imposed by this title” (emphasis
    added) should generally be understood to refer to tax net of refundable credits,
    then other Code sections that refer to “tax imposed by this title” but that do not
    explicitly exclude the netting of credits might become very problematic. Section
    6001 requires that “[e]very person liable for any tax imposed by this title * * *
    shall keep such records * * * as the Secretary may from time to time prescribe”,
    and section 6011(a) requires that a return be filed by “any person made liable for
    any tax imposed by this title”. For taxpayers who are entitled to refundable
    credits, these requirements apply not only if they report a balance due but also if
    they are entitled to a refund. Section 6501(a) provides for assessment of “tax
    imposed by this title” (and the IRS duly assessed the $144 “total tax” that
    petitioners reported on their 2008 return and separately recorded the allowance of
    the credits claimed). Section 6511(a) sets a deadline for the filing of a claim for
    refund of “any tax imposed by this title”. It would be nonsense to suggest that this
    - 46 -
    deadline does not apply where the claimed overpayment arises from refundable
    credits.
    These provisions have always been (rightly) understood to apply where
    there is a tax liability, whether or not that liability has been satisfied by refundable
    credits. That is, it is a truism that “tax imposed” does not generally mean “amount
    of tax due after application of refundable credits”. It is hard to imagine
    administering the provisions listed above if it were otherwise. The inference that
    an internal revenue statute that addresses “tax imposed”--or “tax shown”--without
    mentioning refundable credits must refer to the tax due after such credits is
    manifestly unwarranted.
    Second, the majority states that it “see[s] no evidence of a contrary
    congressional intent” (i.e., intent contrary to its expressio unius construction), but
    it describes no inquiry into the congressional intent that did produce the critical
    language in section 6211. See op. Ct. pp. 19-20. In fact, the clarification in
    section 6211(b)(1) that “[t]he tax imposed * * * and the tax shown * * * shall both
    be determined without regard to” withholding credits is a truism whose presence
    has a historical explanation. After income tax withholding was inaugurated in
    1943, the definition of “deficiency” had to be changed in order to prevent non-
    rebate refunds (i.e., refunds of over-withheld tax) from inappropriately increasing
    - 47 -
    the amount of a deficiency. In 1944 Congress therefore employed and defined the
    concept of a “rebate” refund (now in section 6211(b)(2)) and--important to the
    current discussion--noted that tax “imposed” and tax “shown” did not include the
    relatively new withholding credit. See Feller v. 
    Commissioner, 135 T.C. at 536-538
    .
    At that time, there were no refundable credits. Congress’ 1944 expressio as
    to withholding credits made no implication whatsoever as to the alterius of
    refundable credits that would not exist until 1975. The silence of
    section 6211(b)(1) about refundable credits (which did not then exist) should not
    give rise to an aberrant definition of section 6664(a)(1)(a) that assumes that “tax”
    imposed and shown somehow includes refundable credits not mentioned in either
    statute.
    D.     The rule of lenity calls for a strict construction of the penalty.
    The majority opinion is correct that the “rule of lenity” requires that penalty
    statutes be “construed strictly”, Commissioner v. Acker, 
    361 U.S. 87
    , 91 (1959);
    see op. Ct. pp. 28-29. The majority aptly invokes this canon to conclude “that
    section 6662 does not impose a penalty on the refundable portions of erroneously
    claimed earned income credits, additional child tax credits, and recovery rebate
    credits”, see op. Ct. p. 29; but it fails to observe that the same canon counsels
    - 48 -
    against expanding the penalty to make it apply where refundable credits were
    overstated but “tax” was not understated.
    Applying the rule of lenity, we should construe “tax” strictly to mean tax,
    rather than construing it loosely to mean tax minus refundable credits. We should
    construe “shown as the tax * * * on his return” strictly to mean shown as the tax
    on his return, rather than construing it loosely to mean not really shown as the tax
    on his return.
    IV.   Conclusion
    The parties and the majority agree that the tax “imposed” is $144, and there
    is no dispute that $144 was shown as the “total tax” on line 61 of petitioners’
    return. There is therefore no “underpayment” as defined in section 6664(a)(1)(A)
    and, as a result, no penalty can be imposed under section 6662(a).
    HALPERN and GOEKE, JJ., agree with this dissent.
    - 49 -
    MORRISON, J., dissenting: On their joint federal tax return for 2008, Rand
    and Klugman claimed that they were entitled to three types of refundable credits:
    the earned income credit, the additional child tax credit, and the recovery rebate
    credit. To buttress their claims to these credits, Rand and Klugman falsely
    reported on their tax return:
    (1) that they lived in the United States;
    (2) that their children lived in the United States;
    (3) that they had earned income of $18,148, including $17,200 in wages
    supposedly paid to Rand by the Yeshivas Brisk Institute in Israel.
    Rand and Klugman reported that their total tax liability, before credits, was $144.
    This amount was attributable to self-employment taxes. The refundable credits
    they claimed total $7,471, and they sought a refund of $7,327 ($7,471-$144).
    The statements on the return were false; Rand and Klugman were not
    entitled to the refundable credits they claimed. The issue remaining in this case is
    to determine the amount of their penalty under section 6662.
    Section 6662 imposes a 20% penalty on underpayments associated with
    inaccurate tax returns. For returns that are fraudulent, a 75% penalty applies under
    section 6663. The amount of either penalty is mathematically dependent on the
    amount of the underpayment. The amount of the underpayment is in turn a
    - 50 -
    function of four variables, including “the amount [of tax] shown as the tax by the
    taxpayer on his return”. Sec. 6664(a)(1)(A). This variable is referred to here as
    the “tax shown”. A disagreement about how to calculate this variable divides our
    Judges in this case.
    The Court holds that the “tax shown” for the purpose of calculating an
    underpayment cannot be less than zero. Therefore, the Court holds that the “tax
    shown” on Rand and Klugman’s return is zero. In my view, the “tax shown” on
    the return can be less than zero. I would hold that the “tax shown” on Rand and
    Klugman’s return is $144 (the amount they reported on their return for self-
    employment tax) minus $7,471 (the refundable credits they claimed), which is
    -$7,327.1
    Whether the “tax shown” on a return can be negative, i.e. less than zero, in
    calculating an underpayment is not answered by the plain language of the Internal
    Revenue Code. Section 1 imposes the federal income tax on individuals. It
    provides that a “tax” is “imposed” on “taxable income”. The tax imposed by
    section 1 is supplemented by a “tax” imposed by section 1401(a) on “the self-
    employment income of every individual”. The Code provides for several types of
    1
    The difference between zero and -$7,327 affects the amount of the
    underpayment. If the “tax shown” is zero, the underpayment is $144. If the “tax
    shown” is -$7,327, the underpayment is $7,471.
    - 51 -
    credits “against the” taxes imposed by section 1 and section 1401, among other
    taxes. Some of these credits, including the additional child tax credit, the earned
    income credit, and the recovery rebate credit, are refundable credits. See secs.
    24(d), 32(a), 6428(a). Refundable credits must be refunded by the Internal
    Revenue Service (IRS) to the taxpayer to the extent they exceed the taxpayer’s
    pre-refundable-credit tax liability. See secs. 6402(a), 6401(b).
    I disagree with the Court’s holding for three primary reasons. First, it does
    not give sufficient weight to Congress’s purpose in enacting section 6662.
    Second, it relies too heavily on section 6211(b)(4), a section of uncertain
    relevance to the term in dispute in this case--the term “underpayment”. Third, the
    Court’s holding creates a gap in the penalty regime that Congress could not have
    intended. I address each shortcoming in turn.
    When a law is ambiguous, it is appropriate for a court to interpret the law in
    a manner consistent with Congress’s purpose behind the law. See Thompson v.
    GMAC, LLC, 
    566 F.3d 699
    , 707 (7th Cir. 2009); Yarish v. Commissioner, 
    139 T.C. 290
    , 295 (2012). Sections 6662 and 6664 are ambiguous with respect to the
    meaning of “underpayment” and, specifically, whether “tax shown” can be
    negative. The Court’s strained attempt to arrive at the meaning of “tax shown”
    demonstrates as much. See Yarish v. Commissioner, 
    139 T.C. 295

    statutory phrase ambiguous where “it is susceptible of at least two different
    meanings”). Accordingly, it is appropriate to look to the purpose underlying
    section 6662 to determine the meaning of “underpayment” and “tax shown”.
    The purpose of the section 6662 penalty is to deter taxpayers from taking
    questionable tax return positions that they hope that the IRS will not discover.

    Professor Lawrence Zelenak in his article “Tax or Welfare? The
    Administration of the Earned Income Tax Credit”, 52 UCLA L. Rev. 1867, 1869
    (2005), observes:
    In common with other taxpayer-favorable provisions of the
    federal income tax, the EITC [the earned income tax credit] is
    administered on the basis of self-declared eligibility. As with persons
    claiming other income tax deductions, exclusions, and credits, the
    EITC claimant makes the entries on her tax return required to
    determine the amount of EITC to which she is entitled, and pays less
    (continued...)
    - 53 -
    credits on their tax returns, hope that the IRS will not discover that they are not
    entitled to the credits. In the case of refundable credits, the claimants hope that the
    IRS will write them a refund check (as the IRS did for Rand and Klugman). False
    claims of credits on returns are as difficult for the IRS to detect as falsely reported
    items of gross income or deductions. Treating a false claim of credits as part of
    the “tax shown” on the return, and treating a false claim to refundable credits as
    potentially a report of negative tax, are consistent with the purpose of section
    6662.
    Adopting this interpretation would result in imposing a penalty on Rand and
    Klugman of $1,494.3 This is not an onerous penalty for filing the false return,
    considering the false return was designed to generate an undeserved tax benefit of
    $7,471. By contrast, the Court holds that the appropriate amount of the penalty is
    20% of $144, or $29. That is only about 0.39% (less than one two-hundredth) of
    the tax benefit sought.
    The second reason I contest the Court’s holding is that it relies unduly on
    section 6211(b)(4). The Court uses an elaborate scheme of statutory construction

    to divine the meaning of “underpayment”. The Court assumes that, because “tax
    shown” is used in both section 6664 (defining “underpayment”) and section 6211
    (defining “deficiency”), the phrase has the same meaning in both sections.
    Further, because section 6211(b)(4), which applies exclusively to the definition of
    “deficiency”, contains a negative tax provision, the Court infers that “tax shown”,
    in the absence of the subsection (b)(4) modification, cannot be negative. On the
    basis of these two assumptions, the Court holds that “tax shown” for purposes of
    defining “underpayment” cannot be negative. This reasoning is flawed for four
    reasons.
    First, the Court’s holding implicitly (and incorrectly) assumes that there is a
    sure meaning of “tax shown” (as used in section 6211(a)) without the negative tax
    provision found in subsection (b)(4). This assumption is incorrect, as is illustrated
    by the fact that the Judges in this case cannot agree on the meaning of “tax shown”
    in the absence of subsection (b)(4). Because its meaning is unclear, the Court
    should not rely on it in defining “tax shown” in the definition of “underpayment”.
    The Court holds that “tax shown” (in the absence of subsection (b)(4)) means the
    tax reported on the return, reduced for credits, but not below zero and that
    subsection (b)(4) only provides the mechanism by which we reduce “tax shown”
    into negative territory when calculating a deficiency. Judge Gustafson adopts the
    - 55 -
    view that “tax shown” means the tax reported, unreduced for credits, and that
    subsection (b)(4) provides the mechanism by which we reduce “tax shown” by
    credits in calculating a deficiency and reduce “tax shown” below zero. Under this
    view, in the absence of subsection (b)(4), “tax shown” is not reduced by credits at
    all. These divergent views demonstrate that, while we know the bottom-line result
    of subsection (b)(4)--that refundable credits can reduce “tax shown” below zero
    when calculating a deficiency--we do not know how it achieves this result. This
    suggests that the concept of “tax shown” (as used in section 6211(a), without
    subsection (b)(4)), is an unreliable indicator of Congress’s intended meaning of
    underpayment and that the Court should not rely on it.
    Second, portions of the opinion of the Court suggest that the concepts of
    deficiency and underpayment are separate, yet the Court draws heavily from
    section 6211 (defining “deficiency”) in defining “tax shown” (as used in the
    definition of “underpayment”) and, indirectly, in defining “underpayment”. The
    Court’s approach is inconsistent with Congress’s intent. Congress separated the
    meaning of “underpayment” from the meaning of “deficiency” in 1989. The Court
    acknowledges as much: “[O]ur conclusion breaks the historical link between the
    definitions of a deficiency and an underpayment; however, it was Congress that
    made that break.” See op. Ct. p. 25. Yet the Court adopts a definition of
    - 56 -
    “underpayment” that is necessarily, if indirectly, linked to the meaning of
    “deficiency”. Despite Congress’s attempt to separate the two terms, the Court’s
    holding requires us to scrutinize the meaning of “deficiency” to determine the
    meaning of “underpayment”. The consequences of this approach are illustrated by
    the role that amendments to section 6211(b)(4) have inadvertently played in the
    Court’s definition of “tax shown” (for purposes of an underpayment). Section
    6211(b)(4) has been amended twice since 1989--in 2000 and in 2008--to
    incorporate the child tax credit and the recovery rebate credit.4 Each of these
    amendments changed the definition of “deficiency”. Under the Court’s view, both
    of these amendments also affected the definition of “underpayment” because they
    indirectly changed the meaning of “tax shown” in the definition of
    “underpayment”. Further, there is nothing in the Court’s opinion that suggests
    that future amendments to section 6211(b)(4) will not similarly affect the meaning
    of “tax shown” and, as a result, “underpayment”. In recognition of the fact that
    4
    In 1997 Congress added the additional child tax credit to the Code, and in
    2000 it incorporated the credit in the negative-tax provision of sec. 6211(b)(4).

    122 Stat. at 613 (amending sec. 6428(a)).
    - 57 -
    Congress broke the link between deficiency and underpayment in 1989, the better
    approach would be to ignore section 6211(b)(4) entirely in arriving at the meaning
    of “tax shown”.
    A related problem is that the Court’s holding is not supported by the
    legislative history it cites. See op. Ct. p. 26 (citing H.R. Rept. No. 101-247, at
    1394 (1989), 1989 U.S.C.C.A.N. 1906, 2864). The committee report stated that
    the establishment of a separate definition of “underpayment” in 1989 (separate
    from the definition of “deficiency”) was not intended to change the definition of
    “underpayment”. H.R. Rept. No. 101-247, at 1394, 1989 U.S.C.C.A.N. at 2864.
    But taken literally this would mean that the definition of “underpayment”
    remained unchanged from its pre-1989 definition. Because its pre-1989 definition
    included the negative-tax provision of section 6211(b)(4), that would mean that
    the “tax shown” on the return, which could be negative before 1989, can still be
    negative now.5 But this would mean that the “tax shown” on Rand and
    5
    Before 1989 former sec. 6653(a)(1) and (b)(1) imposed penalties equal to
    percentages of the portions of an underpayment due to negligence (5%) or fraud
    (75%), respectively. Former sec. 6661(a) (repealed 1989) also imposed a penalty
    equal to 25% of the portion of an underpayment due to a substantial
    understatement of income tax. An underpayment was not defined by sec. 6661(a).
    An underpayment for purposes of the 5% negligence penalty and the 75% fraud
    penalty was generally defined the same as a deficiency for income tax returns.
    This rule was found in former sec. 6653(c): “the term ‘underpayment’ means * * *
    (continued...)
    - 58 -
    5
    (...continued)
    a deficiency as defined in [section 6211]”. See Feller v. Commissioner, 
    135 T.C. 497
    , 506-507 (2010). In 1988 Congress amended sec. 6211(b)(4) to add the
    negative-tax provision we summarized above. Technical and Miscellaneous
    Revenue Act of 1988, Pub. L. No. 100-647, sec. 1015(r)(2), 102 Stat. at 357
    (amending sec. 6211(b)(4)). At the time, of the three types of credits Rand and
    Klugman claimed, only the earned income credit was in existence and referenced
    in the negative-tax provision of sec. 6211(b)(4). Thus, sec. 6211(b)(4) provided:
    For purposes of subsection (a)--
    (A) any excess of the sum of the credits allowable under
    sections * * * 32 and 34 over the tax imposed by subtitle A
    (determined without regard to such credits), and
    (B) any excess of the sum of such credits as shown by
    the taxpayer on his return over the amount shown as the tax by
    the taxpayer on such return (determined without regard to such
    credits),
    shall be taken into account as negative amounts of tax.
    Because of the cross-reference of former sec. 6653(c) to the definition of
    “deficiency”, the 1988 amendment modified the definition of “underpayment” for
    purposes of sec. 6653(a)(1) and (b)(1). One year later, in 1989, Congress
    revamped the system of civil tax penalties. Omnibus Budget Reconciliation Act of
    1989 (OBRA), Pub. L. No. 101-239, sec. 7721(a), (c), 103 Stat. at 2395, 2399. It
    repealed former sec. 6653; it added sec. 6662 (the accuracy-related penalty), sec.
    6663 (the fraud penalty--equal to 75% of the portion of the underpayment
    attributable to fraud), and sec. 6664 (setting forth definitions of terms used in secs.
    6662 and 6663). OBRA sec. 7721(a), (c)(1). The word “underpayment”, used in
    sec. 6662 (and sec. 6663), is defined by sec. 6664(a). Secs. 6662(a), 6663(a). The
    1988 amendment modifying the definition of “deficiency” remained in the Code,
    but after 1989 it no longer expressly affected the definition of “underpayment”.
    This is because in 1989 the definition of “underpayment” was detached from the
    (continued...)
    - 59 -
    Klugman’s return should be reduced to -$7,327. This is the opposite of what the
    Court holds. The Court holds that the “tax shown” on the return in underpayment
    calculations cannot be negative. And it holds that the “tax shown” on Rand and
    Klugman’s return is zero. The Court’s holding, whatever its other merits, is not
    supported by the Ways and Means Committee report.
    The fourth problem with the Court’s reliance on section 6211(b)(4) in
    defining “tax shown” (for purposes of an underpayment) is that the approach relies
    too heavily on principles of statutory construction. Recall that the Court’s
    reasoning employs not one, but two principles of statutory construction: the
    principle that the same phrase means the same thing wherever it appears in the
    statute and the principle that all statutory phrases must be given effect. It has been
    recognized that principles of statutory construction rest upon the assumption that
    Congress is all-knowing. See, e.g., Edwards v. United States, 
    814 F.2d 486
    , 488
    (7th Cir. 1987). Thus, for example, when Congress uses the same phrase in a
    5
    (...continued)
    definition of “deficiency”. See Feller v. Commissioner, 
    135 T.C. 507-508
    (“The
    definition of an underpayment is no longer tied to the definition of a deficiency
    under section 6211, as it had been in section 6653(c)”.). Despite the detachment
    of the definition of “underpayment” from the definition of “deficiency”, a report of
    the House Ways and Means Committee asserted that the definition of
    “underpayment” under the 1989 amendments was “not intended to be
    substantively different” from previous law. H.R. Rept. No. 101-247, at 1394
    (1989), 1989 U.S.C.C.A.N. 1906, 2864.
    - 60 -
    statute, it is assumed to do so deliberately because it knows the phrase will be
    construed the same way wherever it appears. This assumption can give rise to
    inaccurate readings, especially where, as here, two principles of statutory
    construction are chained together. For example, it may be reasonable to assume
    that, in using the phrase “tax shown” in sections 6664 and 6211, Congress
    intended that “tax shown” would carry the same meaning in both sections;
    however, it seems inherently less reasonable to assume further that Congress
    intended for section 6211(b)(4) (defining “deficiency”) to be relied upon to define
    “tax shown” (as used in defining “underpayment”). The Court’s chain of
    reasoning seems especially suspect in the light of Congress’s express intent to
    separate the definition of underpayment from the definition of deficiency. See op.
    Ct. pp. 25-26.
    Finally, the majority contends that its holding, which occasions a puny $29
    penalty for Rand and Klugman’s false claim for $7,471 in tax credits, does not
    result in a gap in the penalty regime because there are penalties for false or
    excessive claims for credits found in section 32(k) and section 6676. Section
    32(k), enacted in 1997, provides that a false claim to the earned income credit for
    one tax year results in the denial of the earned income credit for the next two tax
    years “[if] there was a final determination that the taxpayer’s claim of credit * * *
    - 61 -
    was due to reckless or intentional disregard of rules and regulations”.6 Many
    taxpayers who falsely claim the earned income credit for one year will not qualify
    for the credit for the subsequent two years anyway. Rand and Klugman, for
    example, claimed earned income credits for 2006, 2007, and 2008, even though, as
    they have now stipulated, they were not entitled to the earned income credit for
    any of the three years. For such taxpayers as Rand and Klugman, section 32(k),
    even if applicable,7 deprives them of nothing to which they would otherwise be
    entitled. It is doubtful that Congress intended section 32(k) to be the only penalty
    potentially applicable to false refund claims related to earned income credits.
    Section 6676, enacted in 2007, imposes a 20% penalty on overstated claims
    to various types of credits, including the additional child tax credit and the
    recovery rebate credit.8 It is unlikely that Congress thought the section 6676
    6
    The period of disallowance is 10 years if the claim of credit is due to fraud.
    7
    Sec. 32(k) is conditioned upon “reckless or intentional disregard of rules
    and regulations.” Sec. 6662 is not. See sec. 6662(b)(2).
    8
    The Court seems to take the IRS to task for failing to assert the sec. 6676
    penalty against Rand and Klugman. The opinion states: “Such a penalty may
    have applied here, if respondent [the IRS] had asserted it.” See op. Ct. p. 31.
    However, the record does not disclose whether the IRS has asserted a sec. 6676
    penalty. This is not surprising. The present proceeding is a deficiency proceeding
    under sec. 6214. In a deficiency proceeding the Tax Court does not have authority
    to redetermine a taxpayer’s liability for a sec. 6676 penalty, which the IRS can
    (continued...)
    - 62 -
    penalty was a sufficient (or exclusive) penalty for returns that seek refunds based
    on false claims of tax credits. First, the section 6676 penalty does not apply to
    claims to the earned income credit.9 See sec. 6676(a). Second, the percentage of
    the section 6676 penalty is only 20%; however, the penalty related to fraudulent
    returns is 75%. Sec. 6663(a). Under the Court’s approach, a claim for a refund,
    even if fraudulent, is not subject to the 75% fraud penalty. It seems improbable
    that Congress intended such behavior to be so lightly penalized. Third, the section
    6676 penalty applies to “a claim for refund or credit” whether or not made on a
    return. Thus, the section 6676 penalty covers more taxpayer submissions to the
    IRS than the section 6662 and 6663 penalties, which are confined to returns.
    In addition, the Court asserts that Congress’s exemption of the earned
    income credit from section 6676 shows its intent that the section 6662 penalty
    does not reach improper refund claims relating to the earned income credit. See
    op. Ct. p. 32. It says: “And it appears that Congress intended that the two-year
    bar be in lieu of any other monetary sanctions. For example, the penalty under
    8
    (...continued)
    assess without a notice of deficiency. See sec. 6671(a).
    9
    It is the earned income credit that makes up the largest portion of the
    refundable tax credits claimed by Rand and Klugman on their 2008 return. They
    claimed an earned income credit of $4,824, an additional child tax credit of
    $1,447, and a recovery rebate credit of $1,200.
    - 63 -
    section 6676 for an erroneous claim for refund specifically excludes a claim for
    refund relating to an erroneous earned income credit.” See 
    id. I disagree.
    In
    enacting section 6676 in 2007, Congress may have understood that false refund
    claims relating to the earned income credit were already governed by the forfeiture
    penalty under section 32(k) enacted in 1997, the 20% penalty under section 6662,
    and the 75% penalty under section 6663 (if fraudulent). It may have thought that
    the potential applicability of these penalties would be sufficient.
    COLVIN, J., agrees with this dissent.
