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.

      Michael T. Shelton and Lauren N. Hood, for respondent.



                                      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

       The complete name of Form 4852 is Substitute for Form W-2, Wage and
Tax Statement, or Form 1099-R, Distributions From Pensions, Annuities,

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, 

, 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, 

, 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.,

(1984). The first prong of that test is “whether Congress has directly
                                        - 14 -

spoken to the precise question at issue.” 

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.” 

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, 

. 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., 

, 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, 

, 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, 

, 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, 

, 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, 

, 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.

      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., 

, 213 (2001) (quoting Atl. Cleaners & 

). 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

coordinate the definitions in present law; it is not intended to be substantively

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.

, 168 (1993); see also

      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.

Catterall v. Commissioner, 

, 421 (1977), aff’d sub nom. Vorbleski v.

Commissioner, 

(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, 

, 136 (1991); see also

Neuberger v. Commissioner, 

, 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).

           See, e.g., Carlebach v. Commissioner, 

(2012) (imposing a

                                       - 22 -

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, 

, 538-539 (1955)

(“‘The cardinal principle of statutory construction is to save and not to destroy.’

Labor Board v. Jones & Laughlin Steel Corp., 

, 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, 

, 152 (1883), rather than to emasculate

an entire section”.); see also Tucker v. Commissioner, 

, 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.

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. 

(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, 

, 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, 

, 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, 

(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’.” 

(fn. ref. omitted) (quoting FCC v. Am.

Broadcasting Co., 

, 296 (1954), and Keppel v. Tiffin Sav. Bank, 

, 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, 

. 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. __, __, 

, 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

      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

       In Feller v. Commissioner, 

, 526-543 (2010) (Gustafson, J.,

penalty of section 6663; but in one respect the majority’s error in this case is more
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
                                                                          (continued...)

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


      1
       (...continued)
(discussed below) to construe the penalty statute narrowly. Cf. Babbitt v. Sweet
Home Ch. of Comtys. for a Great Or., 

, 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”. 

cl. 1.2 As the Supreme Court observed in Whitman v.

Am. Trucking Ass’ns, 

, 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., 

, 843-845 (1984). Notably, in Feller v. Commissioner, 

(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, 

, 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. 

.

       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, 

, 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, 

, 707 (7th Cir. 2009); Yarish v. Commissioner, 

, 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, 

(finding a
                                       - 52 -

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.

reported on income tax returns. See United States v. Gormley,

(4th Cir. 2000).2 Taxpayers like Rand and Klugman, who make false claims of

       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).

                                        - 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...)

      5
        (...continued)
a deficiency as defined in [section 6211]”. See Feller v. Commissioner, 

, 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, 

, 488

(7th Cir. 1987). Thus, for example, when Congress uses the same phrase in a

      5
        (...continued)
definition of “deficiency”. See Feller v. Commissioner, 

(“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 

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.
