    Before MICHEL, Chief Judge,∗ ARCHER, Senior Circuit Judge, and BRYSON, Circuit
    Judge.
    ARCHER, Senior Circuit Judge.
    Pacific Gas and Electric Company and PG&E Corporation (collectively “PGE”)
    appeal the United States Court of Federal Claims’ judgment that the Internal Revenue
    Service (“IRS” or “Service”) properly offset statutory interest that was erroneously paid
    to PGE (“erroneous interest”) with respect to the tax year 1982, against a later refund of
    tax and interest determined to be due PGE for the same tax year. Pac. Gas & Elec. Co.
    v. United States, 
    55 Fed. Cl. 271
     (2003) (“PGE I”). Because the IRS made this offset
    after the statute of limitations under 
    26 U.S.C. § 6532
    (b) would have precluded the
    government from filing suit to recover the erroneous interest, we reverse.
    ∗
    Chief Judge Paul R. Michel assumed the position of Chief Judge on
    December 25, 2004.
    I
    This case involves statutory interest erroneously paid to PGE for tax year 1982.
    PGE timely filed its 1982 tax return. PGE thereafter filed claims for refund for 1982 and
    the IRS made other adjustments with respect to that year, which are not necessary to
    detail. Suffice it to say that in August 1988, the IRS determined that PGE had overpaid
    its 1982 tax. In determining the statutory interest under 
    26 U.S.C. § 6611
     to be paid to
    PGE on this overpayment, the IRS made errors in its calculation resulting in too much
    interest being paid to PGE.1
    PGE thereafter filed additional refund claims for tax and interest for the tax year
    1982 primarily to claim certain statutorily authorized carryback adjustments from tax
    year 1984.     In reviewing those refund claims, the IRS discovered the interest
    computation errors it had previously made in the August 1988 refund and determined
    that it had erroneously overpaid PGE $3,370,535 in statutory interest. The IRS then
    used the amount of this erroneous interest previously paid to PGE in 1988 to offset and
    reduce the tax and interest for the tax year 1982 that it refunded to PGE in 1992.
    PGE filed suit in the Court of Federal Claims, contending it was entitled to the
    additional amount of $5,037,109 in connection with the 1992 refund.2 PGE argued that
    the IRS was not permitted to offset such erroneous interest against its allowable refund
    1
    The erroneous interest calculation resulted primarily from the treatment of
    one installment payment on June 20, 1983, of tax for 1982, in the amount of
    $63,000,000. In the interest computations, the IRS assumed the due date of the return,
    March 15, 1983, should commence the running of interest, whereas the correct date
    was when the installment payment was made. The IRS also double-counted the
    interest due on a small portion of the overpaid tax
    2
    The offset, while made in 1992, was effective back to the date the
    erroneous interest was paid in August 1988. Thus, PGE claims this larger amount
    because additional interest under section 6611(b)(2) would have accrued on its refund
    that was paid in 1992.
    03-5173                                     2
    of tax and interest in 1992 because it was done after the expiration of the statute of
    limitations for filing suit to recover an erroneous refund under 
    26 U.S.C. § 7405
    .
    
    26 U.S.C. §§ 7405
    , 6532(b).    The government argued that its use of the offset was
    permissible. Both parties moved for summary judgment.
    The Court of Federal Claims held that the IRS’s offset action in 1992 was proper.
    PGE I, 55 Fed. Cl. at 277. Although recognizing that a suit under 
    26 U.S.C. § 7405
     for
    the amount of the erroneously paid interest would have been time-barred, the court said
    “there is no provision in the [Internal Revenue] Code forbidding the administrative
    remedy the Service chose here.” 
    Id. at 276
    . The court was not persuaded by PGE’s
    efforts to distinguish precedent the court found controlling.      Specifically, the court
    explained:
    The most clearly applicable precedents, Lewis, Dysart, and Fisher, all
    contemplate the allowance of an offset by the government when, as here,
    the same tax, taxpayer, and tax year are at issue. Plaintiff has attempted
    to distinguish the facts of this case from Lewis and Fisher. . . . The most
    important fact for the court is that this case involves the same tax, with the
    same taxpayer, for the same tax year. As the Court of Appeals for the
    Federal Circuit stated in Fisher, "Lewis and Dysart together stand for the
    proposition that the government may offset against a tax refund claim any
    additional amounts the taxpayer owes with respect to the tax shown on
    the return, even though the statute of limitations would bar assessing the
    additional amount owed." 80 F.3d at 1579. Here, plaintiff received an
    amount in overpayment with respect to tax year 1982. By requesting
    another refund in 1992 with respect to tax year 1982, plaintiff opened the
    door to the Service's offsetting the 1988 overpayment amount. Therefore,
    the Service's action in 1992 was legal.
    Id. at 277. The court further determined that the offset was implemented correctly.
    PGE now appeals the issues of whether the offset was permissible and, if it was,
    whether      the   IRS   implemented   it   properly.    We    have    jurisdiction    under
    
    28 U.S.C. § 1295
    (a)(3).
    03-5173                                      3

    “We review the Court of Federal Claims’ grant of summary judgment without
    deference.” Agwiak v. United States, 
    347 F.3d 1375
    , 1377 (Fed. Cir. 2003).
    III
    We must determine whether the IRS was entitled to offset the erroneous interest
    paid to PGE in 1988 against amounts due and owing PGE on a subsequent refund
    relating to the same tax year when the government could not have maintained a suit for
    such erroneous interest due to the expiration of the statute of limitations.          See
    
    26 U.S.C. §§ 7405
    , 6532(b).      Surprisingly, this issue appears be one of first
    impression.3
    PGE argues that when a taxpayer receives an erroneous refund of statutory
    interest it is not a tax liability but an ordinary debt obligation to the government. Thus,
    such erroneous interest mistakenly paid cannot be assessed or collected by the IRS in
    the same manner as a tax liability. PGE contends that it must be recovered, if at all,
    3
    Both parties agree that the general statutory offset provision, 
    26 U.S.C. § 6402
    (a), does not apply to this case. Section 6402(a) provides “[i]n the case of any
    overpayment, the Secretary, within the applicable period of limitations, may credit the
    amount of such overpayment, including any interest allowed thereon, against any
    liability in respect of an internal revenue tax on the part of the person who made the
    overpayment and shall . . . refund any balance to such person.” 
    26 U.S.C. § 6402
    (a).
    Internal documents from the IRS indicate that it has long been the Service’s
    position that unless it can assess the amount to be offset, it may not use its statutory
    right of offset under 
    26 U.S.C. § 6402
    . In Chief Counsel Advice 20014033, the Chief
    Counsel of the IRS stated “unless the Service can assess the amount erroneously
    refunded (as in the case of a rebate refund), the Service may not use its statutory right
    of offset under I.R.C. § 6402 to recover the erroneous refund.” IRS CCA 200014033 *9
    (2000); see also IRS GCM 36263 (1975) (stating “[t]he erroneous payment of $900
    cannot be recovered by assessment and offset under Code § 6402 or other tax
    collection procedures, since there is no tax liability”). This may explain why both parties
    agree that 
    26 U.S.C. § 6402
    (a) is inapplicable to the present case, that is, because the
    erroneous interest at issue here is not assessable.
    03-5173                                     4
    only by suit for an erroneous refund under 26 U.S.C § 7405 or by means otherwise
    afforded to the government for collection of debts (e.g., through a common-law right of
    offset, provided that the right is exercised within the period of limitations applicable to
    suits brought under 
    26 U.S.C. § 7405
    ). PGE also asserts that there is no statutory or
    regulatory basis for extending the Supreme Court’s decision in Lewis v. Reynolds, 
    284 U.S. 281
     (1932), and its progeny to non-tax liabilities.
    The government responds simply that under Lewis v. Reynolds and its progeny
    the taxpayer’s 1992 claim for refund of its 1982 overpayment reopened its entire 1982
    liability to redetermination by the IRS. As such, it argues that the remedy of offset was
    available to the IRS.
    A
    Lewis v. Reynolds was an income tax refund suit in which, in response to the
    refund claimed, the Commissioner of Internal Revenue determined that a deduction
    taken on the return, which was previously allowed, had been improperly taken.               In
    determining the amount of the refund, the improper deduction was disallowed by the
    Commissioner.     The limitations period for assessing an additional tax to reflect the
    disallowance of the deduction had passed when the Commissioner acted.                     The
    Supreme Court agreed with the Court of Appeals’ conclusion that the relevant statutory
    provisions “clearly limit refunds to overpayments. It follows that the ultimate question
    presented for decision, upon a claim for refund, is whether the taxpayer has overpaid
    his tax [and t]his involves a redetermination of the entire tax liability.” 
    Id. at 283
     (quoting
    Lewis v. Reynolds, 
    48 F.2d 515
    , 516 (10th Cir. 1931) (emphasis added)). Affirming the
    03-5173                                       5
    Commissioner’s action, the Court stated:
    While the statutes authorizing refunds do not specifically empower
    the Commissioner to reaudit a return whenever repayment is claimed,
    authority therefor is necessarily implied. An overpayment must appear
    before refund is authorized. Although the statute of limitations may have
    barred the assessment and collection of any additional sum, it does not
    obliterate the right of the United States to retain payments already
    received when they do not exceed the amount which might have been
    properly assessed and demanded.
    
    284 U.S. at 283
     (emphases added).          Thus, the Court simply applied the statutory
    provisions dealing with refunds4 which require that an overpayment must be shown by
    the taxpayer before a refund can be authorized. Accordingly, where the taxpayer has
    filed a claim for a tax refund, the IRS may offset against the refund claim a tax
    deficiency for the same tax year that previously had not been assessed, even though
    4
    The refund statutes at issue in Lewis v. Reynolds read as follows:
    (a) Where there has been an overpayment of any income, war-profits, or
    excess-profits tax imposed by this Act (Feb. 26, 1926), the Act entitled “An
    Act to provide revenue, equalize duties, and encourage the industries of
    the United States, and for other purposes,” approved August 5, 1909, the
    Act entitled “An Act to reduce tariff duties and to provide revenue for the
    Government, and for other purposes,” approved October 3, 1913, the
    Revenue Act of 1916, the Revenue Act of 1917, the Revenue Act of 1918,
    the Revenue Act of 1921, or the Revenue Act of 1924, or any such Act as
    amended, the amount of such overpayment shall, except as provided in
    subdivision (d), be credited against any income, war-profits, or excess-
    profits tax or installment thereof then due from the taxpayer, and any
    balance of such excess shall be refunded immediately to the taxpayer.
    
    26 U.S.C. § 284
    (a) (1926) (emphasis added).
    (a) Authorization. Where there has been an overpayment of any tax
    imposed by this title, the amount of such overpayment shall be credited
    against any income, war-profits, or excess-profits tax or installment thereof
    then due from the taxpayer, and any balance shall be refunded
    immediately to the taxpayer.
    
    26 U.S.C. § 322
    (a) (1928) (emphasis added).
    03-5173                                      6
    the assessment of such tax is barred by the expiration of the applicable period of
    limitations.   Otherwise, a refund might be made when there was not, in fact, an
    “overpayment,” an event that would be inconsistent with the statute. See supra at n.4,
    3.
    This defense of “lack of overpayment,” permitting the government to offset a
    refund claim with a tax deficiency for the same tax year owed by the same taxpayer,
    was further explored by our predecessor court in Dysart v. United States, 
    340 F.2d 624
    (Ct. Cl. 1965). In this case, the taxpayer sought a refund of an erroneously assessed
    and collected penalty for the tax year 1954. The government conceded that the penalty
    was collected in error but claimed an offset in view of a tax deficiency that exceeded the
    penalty, despite the fact that the statute of limitations barred the assessment of the tax
    deficiency.5    The court ruled that “the tax penalty is an addition to the tax,
    
    26 U.S.C. § 294
     (1952), and as such is considered as part of the income tax for the
    taxable year. See Rev.Rul 56—492; 1956—2 Cum.Bul. 949.” 
    Id.
     at 626 n.1.
    Another issue before the court was “whether in a suit for refund where both the
    taxpayers’ claim and the government’s setoff concern the same tax for the same year
    by the same taxpayers, the right of the government to assert such a defense is an
    unconditional right . . . or whether . . . such a right is subject to the court’s discretion
    after evaluating the ‘equities’ involved in each particular case.” Id. at 606.6 The court
    5
    The asserted tax deficiency was used only to reduce the taxpayer’s refund
    to zero.
    6
    In reaching the answer to this question, the court discussed the
    differences between setoff and the doctrine of equitable recoupment (a doctrine which
    requires a single transaction be at issue and involves attempts to offset tax liability from
    one year against that for another year or where attempts are made to set off the tax
    liability of one taxpayer against that of a second taxpayer).
    03-5173                                      7
    held that the Supreme Court’s language in Lewis v. Reynolds laid down an “unqualified
    rule that ‘an overpayment must appear before refund is authorized,’” 
    340 F.2d at 629
    (quoting Lewis v. Reynolds, 
    284 U.S. at 283
    ), and that there was nothing to suggest
    “limiting the defense of lack of overpayment where the refund claim and the setoff relate
    to the same tax, for the same year, payable by the same taxpayer,” id. at 629. The
    court further commented that when determining whether there was an overpayment, a
    taxpayer’s “entire tax liability under the particular tax return was open for
    redetermination.” Id. at 628 (emphasis added).
    The Dysart case, therefore, reiterated the necessity of an overpayment before a
    refund can be authorized and held that a court may not look to the equities of a case to
    deny the defense of lack of overpayment to the government.                Contrary to the
    government’s assertion, Dysart did not open the door wider than Lewis v. Reynolds
    already had for the IRS to offset a refund. At most, it simply clarified that setoff applied
    to the refund claim for a tax penalty improperly collected, because a tax penalty is an
    addition to tax and should be considered part of the tax liability.
    Our holding in Fisher v. United States, 
    80 F.3d 1576
     (Fed. Cir. 1996), involved a
    refund claim against which the government offset deficiency interest owed by the same
    taxpayer for the same tax year. Our analysis characterized the teachings of Lewis v.
    Reynolds and Dysart as permitting the government to offset against a tax refund claim
    any tax owed for that year: “Lewis and Dysart together stand for the proposition that the
    government may offset against a tax refund claim any additional amounts the taxpayer
    owes with respect to the tax shown on the return, even though the statute of limitations
    would bar assessing the additional amount owed.” 
    Id. at 1579
     (emphasis added). We
    03-5173                                       8
    also emphasized the necessity of the existence of an overpayment before a refund
    could be authorized. 
    Id. at 1579
     (noting that in Dysart our predecessor court stated “the
    essential principle that a taxpayer suing for a refund of tax for a particular year must
    show that, in actuality, he overpaid that tax”).
    The crux of our decision in Fisher, however, involved the question of whether
    deficiency interest should be treated any differently than the tax deficiency in Lewis v.
    Reynolds or the tax penalty in Dysart.             Looking to the Revenue Code and our
    predecessor court, we held that “for the purposes of offset, interest should [not] be
    treated any differently than other components of tax liability.” Fischer, 
    80 F.3d at 1580
    ;
    see 
    26 U.S.C. § 6601
    (e) (1994) (stating that interest on tax underpayments “shall be
    assessed, collected, and paid in the same manner as taxes” and that any reference “to
    any tax imposed by this title shall be deemed also to refer to interest imposed by this
    section on such tax”); Alexander Proudfoot Co. v. United States, 
    454 F.2d 1379
    , 1382
    (Ct. Cl. 1972) (stating “[t]he Code’s design for such interest is to assimilate it to the tax
    itself . . . . For a long time, deficiency interest has been so closely braided to principal
    that it has been deemed an integral part of the tax”).
    The common thread in these cases is that the refund statute requires that there
    be an actual overpayment of tax to support a refund.           There cannot be such an
    overpayment without taking into account any additional amount of assessable tax,
    interest, or penalty owed by the taxpayer even though such an amount could not be
    assessed and collected because of the running of the statute of limitations.
    03-5173                                       9
    B
    In the instant case, the amount used to offset the refund claim in 1992 was the
    erroneously calculated statutory interest, a nonassessable amount. The assessable
    quantities in Lewis v. Reynolds and its progeny (tax deficiency, deficiency interest, and
    tax penalty) are a part of a taxpayer’s tax liability, whereas nonassessable statutory
    interest is not. Thus, contrary to the government’s assertion, Lewis v. Reynolds and its
    progeny are not directly on point with the case before us. We must, however, decide
    whether to extend this line of cases to cover the situation at issue here. Because the
    courts have distinguished components of tax liability which are assessable amounts
    from statutory interest which is not a tax liability component or assessable, we have
    found no convincing reason the two quantities should be treated the same.           We,
    therefore, decline to extend Lewis v. Reynolds and its progeny to reach the facts of this
    case.
    The tax deficiencies (including assessable interest and penalties) asserted as an
    offset in Lewis v. Reynolds and its progeny are very different from the offset at issue
    here and even treated differently by the Internal Revenue Code. Our case law notes
    the distinctions.   In Proudfoot, 
    454 F.2d 1379
    , for example, our predecessor court
    explained that statutory interest arises simply because the government had possession
    03-5173                                    10
    of the taxpayer’s funds, whereas deficiency interest is additional money due the
    government that arises from the taxpayer’s tax liability:
    [T]he Revenue Code deals quite differently with statutory interest payable
    by the Government on overpayments. Regulated by §§ 6611-6612, that
    form of interest is paid by the United States, not as a refund of interest
    previously paid by the taxpayer on demand of the Service, but simply
    because the Government has had use of money found to belong to the
    taxpayer. . . .
    Id. at 1384; see also Fisher, 
    80 F.3d at 1580
     (“The Internal Revenue Code treats
    [deficiency] interest as an integral part of the liability itself. Thus, 
    26 U.S.C. § 6601
    (e)
    (1994), provides that interest on tax underpayments ‘shall be assessed, collected, and
    paid in the same manner as taxes’ and that any reference ‘to any tax imposed by this
    title shall be deemed also to refer to interest imposed by this section on such tax.’”).
    We are not the only court to treat tax monies differently based on the nature or
    generation of the funds. See O’Bryant v. United States, 
    49 F.3d 340
    , 346 (7th Cir.
    1995); Crocker First Nat’l Bank of S. F. v. United States, 
    137 F. Supp. 573
    , 574 (N.D.
    Cal. 1955) (explaining that a suit to recover an erroneous refund is not a suit “in respect
    of any liability in respect of any tax,” because any tax liability was satisfied when the tax
    was originally paid). In O’Bryant, the taxpayers paid their tax and interest liability in
    advance, which amounts were then assessed. The Service later erroneously sent the
    taxpayers a refund check.      Without reassessing the tax, the Service then instituted
    collection activities and recovered a portion of the erroneous refund. The taxpayers
    sued to quiet title and recover the monies they claimed were unlawfully taken by the
    government.    The Seventh Circuit noted that the refund taxpayers received was a
    nonrebate refund. “Nonrebate refunds are sent to the taxpayer not because the IRS
    determines that the tax paid is not owing but because of mistakes, typically clerical or
    03-5173                                      11
    computer errors.”     O’Bryant, 
    49 F.3d at 342
    .         The court stated that there is a
    fundamental difference between taxpayers’ liability for tax and their obligation, if any, to
    return a refund paid by mistake:
    [The government’s proposed] approach would overlook the fundamental
    difference in character between the money that the O'Bryants now
    possess (a refund caused by the IRS' error) and the money they originally
    owed the IRS (their tax liability). The money the O'Bryants have now is not
    the money that the IRS' original assessment contemplated, since that
    amount was already paid. Rather, it is a payment the IRS accidentally sent
    them. They owe it to the government because they have been unjustly
    enriched by it, not because they have not paid their taxes.
    
    Id. at 346
    . The court held that because the money the taxpayer received was not a part
    of the taxpaying transaction, the Service could not recover the funds through post-
    assessment procedures. 
    Id.
    A tax deficiency, tax penalty, and deficiency interest, the quantities permitted to
    offset the taxpayer’s claimed refunds in Lewis v. Reynolds and its progeny, are all
    components of a taxpayer’s tax liability. See Dysart, 
    340 F.2d at
    626 n.1 (“[T]he tax
    penalty . . . is considered as part of the income tax for the taxable year.”); Proudfoot,
    454 F.2d at 1382 (“[T]he Code’s design for such [deficiency] interest is to assimilate it to
    the tax itself. . . . For a long time, deficiency interest has been so closely braided to
    principal that it has been deemed an integral part of the tax.”).          Therefore, these
    components are taken into account in determining whether an overpayment exists and
    permitting them to offset a claimed tax refund is logical.         There is no suggestion,
    however, that statutory interest is a part of, or even related to, a taxpayer’s tax liability.
    Indeed it cannot be, for in the case of statutory interest mistakenly paid, the taxpayer
    has no underlying statutory obligation under the tax code to pay the government. As
    stated in O’Bryant, mistaken nonrebate refunds are owed to the government by reason

    of unjust enrichment.          O’Bryant, 
    49 F.3d at 346
    .          Statutory interest is also
    distinguishable from the components of tax liability because of its nonassessable
    nature. Given that a nonassessable quantity cannot be determined to be due and
    collectable, see West’s Tax Law Dictionary 67 (2004 ed.) (defining “assess” as “[t]he
    posting of tax, penalty, and interest that has been determined to be due and
    collectable”), it would be illogical to treat such a quantity as analogous to a taxpayer’s
    tax liability.
    The tax code provides an integrated and comprehensive statutory scheme for
    assessing, collecting, and refunding taxes, deficiency interest, and penalties. Lewis v.
    Reynolds and its progeny did not disturb this framework; they merely applied the refund
    provision requiring an overpayment.          Were we to hold that the IRS is correct in
    determining that an offset is permissible here, we would be going outside of this well-
    tailored statutory scheme. We, therefore, decline to extend Lewis v. Reynolds to apply
    to statutory interest improperly paid to PGE.

    The only case we have found that deals with erroneously refunded statutory
    interest is factually distinguishable from the instant case. In Crocker, 
    137 F. Supp. 573
    ,7 the government offset erroneously paid interest for tax year 1942 against a refund
    for tax year 1945. The court stated that “since it [is] obvious that the offset claimed by
    the Commissioner must be the equivalent of a cause of action by the Government in a
    suit to recover the erroneous payment, the parties [do] not dispute that the time
    limitation for suit applie[d] equally to the offset.” Id. at 574. The offset in Crocker was

    03-5173                                        13
    not made within two years after the payment of the erroneous interest on the 1942
    refund. Another question before the court was whether a wartime statute suspending
    certain time limitations relating to internal revenue operated to extend the time in which
    suit might have been brought to recover the interest paid on the 1942 refund and
    consequently the time in which the offset could be made. The court determined that the
    offset had not been timely made and entered judgment for the taxpayer.
    As can be seen, Crocker dealt with applying the offset to a refund claim for a
    different tax year, whereas in this the case the offset was applied to a claimed refund in
    the same tax year. Moreover, the court noted that the government conceded that the
    statute of limitations pertaining to when the United States may sue to recover erroneous
    refunds of taxes or erroneous payments of interest on refunds applied, whereas in this
    case the government makes no such concession. While readily distinguishable on the
    facts, Crocker does equate the ability to offset erroneously or mistakenly paid statutory
    interest with a cause of action by the government to sue for an erroneous refund under
    § 7405.
    Like the court’s determination in Crocker, we view the offset claimed by the
    Service here as akin to a cause of action by the government in a suit to recover the
    erroneous interest. As noted in Crocker, while there is no statute governing the time
    limit for when such an offset may be made, there is a statute expressly limiting when the
    government can sue to recover erroneous refunds under 
    26 U.S.C. § 7405
    . Id. at 574
    (“There is no limitation statute specifically fixing the time within which such an offset
    may be made. There is, however, a statute, limiting to two years, the time within which
    the United States may sue to recover erroneous refunds of taxes or erroneous
    03-5173                                    14
    payments of interest on refunds.”). We see no reason why this statute of limitations
    should not apply equally to the offset in this case. Thus, we hold that the Service’s
    ability to offset erroneously paid statutory interest against a taxpayer’s refund claim in
    the same tax year is subject to the same statute of limitations that applies to suits by the
    United States to recover erroneous refunds of taxes or erroneous payments of interest
    on refunds. See 
    26 U.S.C. §§ 6532
    (b), 7405.
    Recent decisions internal to the IRS are not at odds with our determination today.
    Indeed, the Chief Counsel of the IRS expressly approved of the Crocker decision and
    further explained “we are of the opinion that as long as the Service is unable to assess
    nonrebate refunds, the Service may justifiably rely on the common law right of offset to
    recover these non-tax debts. The applicable statute of limitations for this remedy is the
    two or five8 year period set forth in I.R.C. § 6532(b).” IRS CCA 200014033.9 While not

    “[I]f the refund is induced by fraud or misrepresentation of material fact.”
    
    26 U.S.C. § 6532

    This reasoning dovetails with earlier IRS decisions. In a 1975 General
    Counsel Memorandum it is stated:
    Suppose for instance, the taxpayer files a return showing no tax liability
    and claims a refund of tax withheld of $100. The Service erroneously
    issues a check in the amount of $1000. The erroneous payment of $900
    cannot be recovered by assessment and offset under Code § 6402 or
    other tax collection procedures, since there is no tax liability. A civil suit to
    recover the refund under Code § 7405 is therefore the Service's sole
    remedy, except we believe it is proper in this instance for the Service to
    exercise a common law right of offset by deducting the amount claimed
    under Code § 7405 from any refund due the taxpayer. Since the amount
    so claimed is not a tax liability and could never have been collected under
    the tax recovery provisions of the Code, the procedural safeguards given
    to the taxpayer by those provisions will not be frustrated by use of
    common law offset in this situation. We therefore conclude that such
    offset may be here exercised within the time limitations prescribed by
    Code § 6532(b).

    bound by the Service’s position, we simply note that our analysis has led us to the
    position espoused by the Service for at least the last thirty years.
    Indeed, Lewis v. Reynolds is now over seventy years old. Congress and the IRS
    have had ample time to provide specific authority that would have broadly allowed the
    offset the government is seeking in this case. Indeed, if it were intended to allow the
    government to recover mistaken payments of statutory interest (and other non-tax
    debts) by way of offset, and not merely tax liabilities used to determine whether there
    was an overpayment of tax, the tax code or the regulations could have so stated.
    In the present case the offset occurred after the two-year statute of limitations
    had expired. As such, the Service’s right to offset was time-barred.10 Because we hold
    that the offset applied here was not available to the IRS, the issue of whether the IRS
    correctly implemented the offset is moot.

    We do not accord these internal documents Skidmore or any other type of
    deference. See Skidmore v. Swift & Co., 
    323 U.S. 134
     (1944); see also IRS GCM
    36263 *13 (stating “This document is not to be relied upon or otherwise cited as
    precedent by taxpayers.”). We merely note that the Service has taken the position that
    offsets of nonassessable quantities against tax refunds must be made within the statute
    of limitations set forth in 
    26 U.S.C. § 6532
    (b).

    The government argues that the doctrine of equitable recoupment
    supports the judgment below. The applicability of the doctrine of equitable recoupment
    does not appear to have been raised below, and, in any event, it was not decided by the
    Court of Federal Claims. This doctrine is only available in very limited circumstances.
    In this connection:
    Congress has chosen to incorporate the doctrine of “equitable
    recoupment” into our revenue laws by what is now commonly known as
    the mitigation provisions of 1311-1315 of the Internal Revenue Code of
    1954. In so doing, Congress has enumerated a series of requirements
    which have to be met before these sections become operative and
    recoupment allowed. It is significant that none of these requirements are
    based on equitable considerations.

    Our decision today results in a windfall for the taxpayer. As the Seventh Circuit
    has noted in a similar situation, “although it may seem unjust that the IRS cannot
    recover its erroneous refund in this case, . . . we cannot base our resolution of the issue
    before us on the equities of a particular factual situation. . . . [T]here are many situations
    in which permitting the IRS to recover would be just as unfair as barring recovery here.”

    We hold that the offset applied to PGE’s 1992 refund claim was time-barred.
