    v.
    STATE TAX ASSESSOR
    HUMPHREY, J.
    [¶1]      Somerset Telephone Company and affiliated corporations
    (collectively, Somerset)1 appeal from a judgment entered in the Business and
    Consumer Docket (Murphy, J.) in which the court affirmed the State Tax
    Assessor’s denial of Somerset’s request for an income tax refund for the 2013
    taxable year. Somerset argues principally that the trial court should have
    granted its petition because the Assessor’s application of Maine’s corporate
    income tax statutes resulted in an unconstitutional indirect tax on
    extraterritorial income that was not subject to taxation in Maine. We affirm the
    judgment.
    1 See infra n.7. Telephone and Data Systems, Inc., the parent corporation of Somerset Telephone
    Company, was also listed on the appellants’ notice of appeal and was a party to the proceedings in
    the trial court.

    I. BACKGROUND
    A.       Legal Background
    [¶2] A brief review of some of the relevant legal concepts and statutory
    definitions is helpful in understanding the factual and procedural background
    in this case. Beginning broadly, pursuant to the Due Process and Commerce
    Clauses of the United States Constitution, “[a]s a general principle, a [s]tate may
    not tax value earned outside its borders.”2 ASARCO Inc. v. Idaho State Tax
    Comm’n, 
    458 U.S. 307
    , 315 (1982); see U.S. Const. amend. XIV, § 1; U.S. Const.
    art. I, § 8, cl. 3; Container Corp. of Am. v. Franchise Tax Bd., 
    463 U.S. 159
    , 164
    (1983).      State governments may constitutionally tax—on an apportioned
    basis—the income of a business operating in multiple states if the business
    activity that generated the income is properly characterized as part of a
    “unitary business.” Container 
    Corp., 463 U.S. at 165-70
    ; see Exxon Corp. v. Dep’t
    of Revenue, 
    447 U.S. 207
    , 223-24 (1980); Mobil Oil Corp. v. Comm’r of Taxes,
    
    445 U.S. 425

    2008 ME 171
    ,
    ¶¶ 11-12, 
    959 A.2d 741
    . Put another way, “[i]f a company is a unitary business,
    This constitutional limitation “derives from the virtually axiomatic proposition that the exercise
    2
    of a state’s tax power over a taxpayer’s activities is justified by the protection, opportunities, and
    benefits the state confers upon those activities. If the state lacks a minimum connection or definite
    link with the taxpayer’s activities, and thus with the property, income, or gross receipts related to
    those activities, it has not given anything for which it can ask return.” 1 Jerome R. Hellerstein et al.,
    State Taxation § 8.07[1] at 8-72 (3d ed. 2000) (footnote omitted) (quotation marks omitted).
    3
    then a [s]tate may apply an apportionment formula to the taxpayer’s total
    income in order to obtain a rough approximation of the corporate income that
    is reasonably related to the activities conducted within the taxing [s]tate.”

    [¶3]     Like   many other       states,   Maine   applies    this   “unitary
    business/formula apportionment approach” to quantify unitary business
    income and identify the portion of that income that is fairly taxable by Maine.

    2020 ME 81

    235 A.3d 837
    . Indeed, “unitary business” is defined by Maine
    statute as “a business activity which is characterized by unity of ownership,
    functional integration, centralization of management and economies of scale.”
    36 M.R.S. § 5102(10-A) (2021). The term “unitary group,” which is not defined
    by statute, refers to a group of corporations whose members are engaged
    4
    together in a unitary business. See Fairchild Semiconductor Corp. v. State Tax
    Assessor, 
    1999 ME 170

    Tax Assessor, 
    675 A.2d 963
    , 964 (Me. 1996).
    [¶4] Maine’s corporate income tax is imposed by a statute that provided,
    during the years at issue in this case, that “[a] tax is imposed for each taxable
    year . . . on each taxable corporation and on each group of corporations that
    derives income from a unitary business carried on by 2 or more members of an
    affiliated group.”3 36 M.R.S. § 5200(1) (2011).4 As we have stated, therefore,
    “If a group of corporations meets the definition of a unitary business, . . . [it is]
    taxed as a single business pursuant to Maine law.” Fairchild Semiconductor
    Corp., 
    1999 ME 170

    a unitary business carried on by 2 or more members of an affiliated group with
    business activity that is taxable both within and without [Maine], ‘income’
    3 An “affiliated group” is “a group of 2 or more corporations in which more than 50% of the voting
    stock of each member corporation is directly or indirectly owned by a common owner or owners,
    either corporate or noncorporate, or by one or more of the member corporations.” 36 M.R.S.
    § 5102(1-B) (2021).
    4  Title 36 M.R.S. § 5200(1) has since been amended but not in a way that affects our analysis in
    this case. See P.L. 2017, ch. 474, § E-1 (emergency, effective Sept. 12, 2018) (codified at 36 M.R.S.
    § 5200(1) (2021)).
    5
    means the net income of the entire group.” 36 M.R.S. § 5200(4) (2011).5 “Maine
    net income,” in turn, “means, for any taxable year for any corporate taxpayer,
    the taxable income of that taxpayer for that taxable year under the laws of the
    United States as modified by” statutory additions and subtractions and
    apportionable pursuant to Maine statutes. 36 M.R.S. § 5102(8) (2011);6 see also
    36 M.R.S. § 5200(5) (2021). Thus, for purposes of Maine corporate taxation,
    “net income” is the federal taxable income for the tax year as modified and
    apportioned pursuant to Maine’s statutes.
    Id. §§ 5102(8), 5200(5).
    [¶5] One of the statutory modifications that must be made to a unitary
    group’s federal taxable income is a subtraction of any income that Maine cannot
    constitutionally tax, 36 M.R.S. § 5200-A(2)(F) (2021), which includes
    “nonunitary” income—income from sources outside the group’s unitary
    business activity, see, e.g., Gannett Co., 
    2008 ME 171
    , ¶ 17, 
    959 A.2d 741
    . After
    this and any other modifications to the unitary group’s federal taxable income,

    . Somerset Telephone
    Company is a small landline telecommunications company located in North
    Anson. During the 2012 and 2013 tax years, Somerset Telephone Company and
    about 180 other corporations were members of a unitary group known as the
    TDS Group. All of the TDS Group’s members were engaged together in a unitary
    business, although only some of them—Somerset, the affiliated taxpayer group
    at issue here—conducted business activity in Maine.7 Income earned by the
    TDS Group’s unitary business—unitary income—was generated both within
    and outside Maine. Some TDS Group members also earned income from
    sources separate from the unitary business.8 This nonunitary income was
    7 This subset includes Somerset Telephone Company; it does not include Telephone and Data
    Systems, Inc. The taxpayer entity listed on the Maine tax returns included in the stipulated record is
    “SOMERSET TELEPHONE CO & AFFIL.” The record indicates that more than twenty TDS Group
    members conducted business activity in Maine during the tax years at issue, 2012 and 2013, and that
    for those tax years, a single Maine return, including an attached “combined report,” was filed on
    behalf of all of these Maine-nexus TDS Group members. See 36 M.R.S. §§ 5220(5), 5244 (2021);
    18-125 C.M.R. ch. 810, §§ .02, .05 (effective Sept. 12, 2010). The Assessor does not dispute that all of
    the Maine-nexus TDS Group members were members of the affiliated group and engaged in the
    unitary business. See 36 M.R.S. § 5220(5).
    The parties agree that—unlike in Fairchild Semiconductor Corp.—the corporations that earned
    8
    nonunitary income were members of the TDS Group, the unitary group at issue here. See Fairchild
    Semiconductor Corp. v. State Tax Assessor, 
    1999 ME 170
    , ¶¶ 2-3, 
    740 A.2d 584
    .

    derived entirely from business activities occurring outside Maine and was not
    subject to Maine taxation.
    [¶7] In the 2012 tax year, the TDS Group had no unitary income—its
    unitary business experienced a loss of approximately $131 million. However,
    the nonunitary income earned by its members amounted to approximately
    $149 million. The TDS Group’s federal taxable income, which netted the
    group’s unitary loss against its nonunitary income, was therefore a positive
    number—approximately $18 million. See 26 U.S.C.S. § 63(a) (LEXIS through
    Pub. L. No. 116-282).
    [¶8] In October 2013, Somerset, the subset of TDS Group members that
    conducted business in Maine during 2012 and 2013, filed a 2012 Maine
    corporate income tax return. The return first listed the TDS Group’s federal
    taxable income of approximately $18 million. Various modifications in the form
    of additions and subtractions were then applied to that figure pursuant to
    36 M.R.S. § 5200-A (2011).9 One of the modifications—the subtraction of $149
    million representing the nonunitary income received by TDS Group members
    in 2012—was applied pursuant to 36 M.R.S. § 5200-A(2)(F). The modifications
    9 Portions of 36 M.R.S. § 5200-A have since been amended but not in ways relevant to the issues
    in this appeal. See, e.g., P.L. 2019, ch. 659, § I-2 (effective June 16, 2020) (codified at 36 M.R.S.
    § 5200-A(2)(AA) (2021); P.L. 2019, ch. 527, §§ A-3, A-4 (effective Sept. 19, 2019) (codified at
    36 M.R.S. § 5200-A(2)(AA), (FF) (2021)).

    resulted in “adjusted federal taxable income” of approximately negative $162
    million, and thus Somerset had no Maine corporate income tax liability for the
    2012 tax year.
    [¶9] Before filing its Maine corporate income tax return for the 2013 tax
    year, Somerset sought a ruling from Maine Revenue Services permitting it to
    “carry forward,” as a deduction from the TDS Group’s 2013 federal taxable
    income, the $131 million unitary business loss that the TDS Group realized in
    2012. Somerset argued that if the TDS Group had hypothetically not received
    any nonunitary income in 2012, it would have been entitled to take a net
    operating loss carryforward deduction in 2013,10 and that disallowing the
    deduction would therefore increase Somerset’s 2013 Maine tax liability due to
    the TDS Group’s receipt of extraterritorial nonunitary income in 2012.
    Somerset proposed accounting for the 2012 unitary loss by subtracting $131
    million from its 2013 federal taxable income for Maine either as a net loss
    carryforward deduction or as a modification pursuant to 36 M.R.S.
    10 The Internal Revenue Code permits deduction of net operating losses as part of the calculation
    of “taxable income,” 26 U.S.C.S. §§ 63(a), 172(a)-(c) (LEXIS through Pub. L. No. 116-259), and defines
    “net operating loss” as “the excess of the deductions allowed . . . over the gross income,” 26 U.S.C.S.
    § 172(c). “In other words, if, after all allowable deductions are taken in a given tax year, a taxpayer
    ends up with a negative number, that figure is a ‘net operating loss’ that can be carried over or back
    to other tax years and used as a deduction in those other tax years pursuant to section 172 of the
    Internal Revenue Code.” Fairchild Semiconductor Corp.,

    , ¶ 1 n.2, 
    740 A.2d 584

    § 5200-A(2)(F). The Assessor, in a nonbinding advisory ruling, rejected both
    alternatives. See 5 M.R.S. § 9001 (2021).
    [¶10] In compliance with the advisory ruling, Somerset filed its 2013
    Maine tax return showing positive Maine taxable income and a state income tax
    liability. It later filed an amended 2013 return on which it listed an adjusted
    federal taxable income that had been reduced by the TDS Group’s 2012 $131
    million net operating loss, resulting in a decreased (but still positive) Maine
    taxable income and decreased tax liability. Somerset requested a partial refund
    to account for the difference. The Assessor denied the refund claim and
    Somerset’s subsequent request for reconsideration.
    [¶11] In April 2017, Somerset filed a five-count petition for review and
    de novo determination in the Superior Court (Kennebec County).11 See 5 M.R.S.
    §§ 11001(1), 11002 (2021); 36 M.R.S. § 151(2)(E)-(G) (2021); M.R. Civ. P. 80C.
    After the matter was transferred to the Business and Consumer Docket, the
    parties filed exhibits and statements of stipulated facts and, later, a corrected
    stipulation of certain facts. Somerset moved for a summary judgment, and the
    11In Count 1, Somerset alleged that the Assessor’s decision ran contrary to the language of Maine’s
    corporate income tax statutes; in Counts 2 and 3, it alleged that the decision resulted in a tax scheme
    that violated the United States and Maine Constitutions. Somerset has not invoked the Maine
    Constitution on appeal. In Counts 4 and 5, Somerset sought relief in the form of alternative
    apportionment, see, e.g., State Tax Assessor v. Kraft Foods Grp., Inc., 
    2020 ME 81
    , ¶¶ 1 n.2, 14-15, 
    235 A.3d 837
    , but on appeal it has not challenged the trial court’s judgment in the Assessor’s favor on
    those counts.
    10
    Assessor opposed the motion. The trial court held a nontestimonial hearing
    and issued an order denying Somerset’s motion for summary judgment. Based
    on the parties’ agreement that no factual or legal issues remained for
    adjudication, the court entered a final judgment in the Assessor’s favor.
    Somerset timely appealed from the judgment. See 14 M.R.S. § 1851 (2021); M.R.
    App. P. 2B(c)(1). After oral argument, we requested supplemental memoranda,
    which the parties supplied.
    II. DISCUSSION
    [¶12] Because the trial court’s review of the Assessor’s decision was
    de novo, see 36 M.R.S. § 151(2)(G), we review the court’s interpretation of the
    applicable statutes and constitutional provisions directly, without deference to
    the Assessor’s legal determinations, Kraft Foods Grp., 
    2020 ME 81
    , ¶ 13, 
    235 A.3d 837
    . We review questions of constitutional and statutory interpretation
    de novo. Goggin v. State Tax Assessor, 
    2018 ME 111
    , ¶ 20, 
    191 A.3d 341
    (constitutional provisions); Irving Pulp & Paper, Ltd., 
    2005 ME 96
    , ¶ 8, 
    879 A.2d 15
    (statutes).
    [¶13] To address the question at issue on appeal, we review (A) whether
    the deduction of a hypothetical federal net operating loss is authorized by
    Maine’s statutes and (B) whether the Constitution demands that such a net
    operating loss be allowed.
    11
    A.    Statutory Interpretation
    [¶14] We construe Maine’s tax statutes based on their plain language “to
    effectuate the intent of the Legislature,” considering “the language in the
    context of the whole statutory scheme.” Eagle Rental, Inc. v. State Tax Assessor,
    
    2013 ME 48
    , ¶ 11, 
    65 A.3d 1278
    (quotation marks omitted). As summarized
    above, Maine uses federal taxable income as a starting point for calculating the
    income that is taxable in Maine. See 36 M.R.S. §§ 5102(8), 5200(5). The
    Legislature did not, by beginning with federal taxable income, adopt and
    incorporate theoretical federal loss carryover deductions that are at odds with
    explicit statutory language in Maine establishing a tax based on the federal
    taxable income of the taxpayer for a taxable year. See
    id. § 5102(8). [¶15]
      Although in federal taxation, “a taxpayer may carry its net
    operating loss either backward to past tax years or forward to future tax years
    in order to set off its lean years against its lush years, and to strike something
    like an average taxable income computed over a period longer than one year,”
    United Dominion Indus. v. United States, 
    532 U.S. 822
    , 825 (2001) (quotation
    marks omitted), no such provision was made in the Maine statutes that applied
    to the tax years at issue here. In Maine at the relevant time, a corporation was
    taxed on its “Maine net income,” meaning the federal taxable income “for that
    taxable year . . . as modified by section 5200-A and apportionable to this State
    12
    under chapter 821 [36 M.R.S. §§ 5210-5212 (2011)12].” 36 M.R.S. § 5102(8)
    (emphasis added); see also
    id. § 5200(5). “To
    the extent that it derives from a
    unitary business carried on by 2 or more members of an affiliated group, the
    Maine net income of a corporation is determined by apportioning that part of
    the federal taxable income of the entire group that derives from the unitary
    business.”
    Id. § 5102(8). [¶16]
    Section 5200-A prescribes several additions and subtractions as
    modifications to the taxable income of the taxpayer for the tax year.
    See 36 M.R.S. § 5200-A. Pertinent here, any nonunitary income realized during
    the taxable year is subtracted from the federal taxable income as “[i]ncome this
    State is prohibited from taxing under the Constitution of Maine or the United
    States Constitution to the extent that it is included in the taxpayer’s federal
    taxable income.” 36 M.R.S. § 5200-A(2)(F). Only limited subtractions related
    to net operating losses were allowed pursuant to Maine’s statute governing
    modifications, and those subtractions did not apply for purposes of the taxation
    at issue here. See, e.g.
    , id. § 5200-A(1)(H), (2)(H).
    [¶17] After the additions and subtractions are made, “[i]n order to
    determine the portion of a unitary group’s income that is properly taxable by
    12 These statutes have since been amended or repealed, though the statutes in chapter 821 still
    require apportionment. See P.L. 2019, ch. 401, §§ C-9, C-10 (effective Sept. 19, 2019) (codified at
    36 M.R.S. §§ 5210-5211 (2021)).
    13
    Maine when the group has non-Maine source income, the Maine Tax Code
    requires that the apportionment formula be applied to the federal taxable
    income of the entire unitary group as a single entity.” Fairchild Semiconductor
    Corp., 
    1999 ME 170
    , ¶ 10, 
    740 A.2d 584
    ; see 36 M.R.S. § 5211.13
    [¶18] Considering these statutes together, although Maine relies on a
    federal taxable income figure as a starting point for the calculation of the
    taxable income in Maine for a tax year, Maine’s statutes express no purpose or
    requirement that the Tax Assessor look behind a taxpayer’s federal taxable
    income in other tax years to determine whether a carryforward or carryback
    should be permitted for the tax year in question. Somerset’s argument that
    Maine is indirectly taxing nonunitary income is based primarily on a United
    States Supreme Court opinion in which, unlike the circumstances here, the
    taxpayer challenged a statute affecting a deduction from income received
    within a tax year. Hunt-Wesson, Inc. v. Franchise Tax Bd., 
    528 U.S. 458
    , 460-63
    (2000). Specifically, the Supreme Court reviewed a California statute that
    13   As the apportionment statute provided, and still provides,
    Any taxpayer, other than a resident individual, estate, or trust, having income from
    business activity which is taxable both within and without this State, other than the
    rendering of purely personal services by an individual, shall apportion his net income
    as provided in this section. Any taxpayer having income solely from business activity
    taxable within this State shall apportion his entire net income to this State.
    36 M.R.S. § 5211(1) (2011); 36 M.R.S. § 5211(1) (2021).
    14
    permitted a deduction of interest expenses from gross income only to the
    extent that the expenses exceeded the taxpayer’s nonunitary income within the
    tax year.
    Id. [¶19]
    In contrast, here the taxpayer is seeking an income modification
    based on a loss taken on its federal return in another tax year. The group was
    not eligible for a net operating loss carryforward on its 2013 federal tax return
    because it had already accounted for the loss in calculating its federal taxable
    income in 2012. Whether Somerset was eligible for a carryforward in Maine on
    its 2013 tax return must be determined by the application of Maine statutes
    governing income modifications and apportionment, see 36 M.R.S. §§ 5200-A,
    5211, based on the actual figures reported for the year 2013, beginning with
    the amount of the TDS Group’s federal taxable income for that year. To create
    a hypothetical scenario in which the TDS Group did not have any nonunitary
    income in 2012 and therefore the amount of the federal taxable income for
    2013 would have been different, as Somerset urges us to do so, does not
    comport with the plain mandates of Maine’s statutory scheme.
    [¶20] No statute was in place that required or allowed any addition or
    subtraction of a carryover that could have been taken if the unitary group
    subject to federal taxation had received only unitary income—for instance, if
    its members had reorganized themselves such that all nonunitary business was
    15
    conducted by separate, nonmember entities. When the Maine Legislature has
    addressed net operating loss carryforwards through the statute governing
    modifications, it has done so explicitly; for instance, as to the tax years 2009,
    2010, and 2011, the Legislature required the amount of the federal loss
    carryforward to be added to the federal taxable income for purposes of
    calculating Maine net income for those years. See 36 M.R.S. § 5200-A(1)(V).
    Any losses carried forward to 2009, 2010, or 2011 could then, in certain
    circumstances, be deducted in Maine beginning in 2012.             See 36 M.R.S.
    § 5200-A(2)(H). The Maine statutes governing modification that were in effect
    for the 2012 and 2013 tax years did not require or permit any addition or
    subtraction based on the taxpayer’s federal taxable income for other taxable
    years.
    [¶21] Although in Fairchild Semiconductor, 
    1999 ME 170
    , 
    740 A.2d 584
    ,
    we interpreted Maine’s statutes to require an adjustment to the federal taxable
    income reported on a return because the federal and Maine unitary groups had
    different memberships, we clearly distinguished those circumstances from a
    situation like that which is before us here, where the calculation of the unitary
    income—not the identity of the unitary group’s members—is at issue.
    Id. ¶¶ 11, 15-16.
    We noted that, although the federal taxable income had to be
    recalculated for the Maine taxpayer group for the tax year in question, the
    16
    taxpayer there did not seek to “manipulate . . . income or losses in a way that
    would change . . . treatment pursuant to the Internal Revenue Code.”
    Id. ¶ 16;
    see also
    id. ¶¶ 13-16
    (distinguishing cases); cf. Graham v. State Tax Comm’n, 
    369 N.Y.S.2d 863
    (N.Y. App. Div. 1975) (requiring the state’s taxing authority to
    allow a nonresident individual a deduction for a net operating loss when the
    federal return for that year did not report a loss due entirely to out-of-state
    income). We emphasized that the Maine taxpayer group in Fairchild was not
    “trying to reconfigure or recalculate its income. Rather the group merely
    s[ought] treatment as a separate entity” without regard to the income of other
    corporations with which it was affiliated for federal tax purposes. Fairchild
    Semiconductor, 
    1999 ME 170
    , ¶ 15, 
    740 A.2d 584
    .
    [¶22] We specifically distinguished the facts in Fairchild Semiconductor
    from those in Tiedemann v. Johnson, 
    316 A.2d 359
    , 360-61 (Me. 1974), where a
    taxpayer sought to report income in different years at the federal and state
    levels. We held that Fairchild Semiconductor’s situation as a taxpayer was
    different because it was merely seeking “separate treatment for its unitary
    group the one and only time the federal taxable income of the group is
    calculated.”   Fairchild Semiconductor, 
    1999 ME 170
    , ¶ 16, 
    740 A.2d 584
    (emphasis added). That is not the case in the matter before us, where the
    unitary group in essence seeks a recalculation of its 2012 federal taxable
    17
    income for purposes of taking a loss in Maine for the 2013 taxable year.
    Although in Fairchild Semiconductor, we applied federal law to determine the
    federal taxable income of the reconstituted group “for that taxable year,”
    36 M.R.S. § 5102(8), we did not thereby require a separate application of
    federal law to every conceivable taxable year in which a loss carryover could
    have been generated if the group itself had been configured differently so that
    it had no nonunitary income.14
    [¶23] Other states have considered the consequences of federal net
    operating loss carryovers and held that, absent a state’s statutory authorization,
    a loss may not be carried over on a state return to a tax year other than the year
    for which a loss was actually claimed on a federal tax return.15 In New York, the
    14 The dissent ignores this distinction and asserts that the existence of a net operating loss in 2012
    necessitates a 2013 deduction, even though Maine’s statutes did not authorize that deduction for the
    2013 tax year. See 36 M.R.S. § 5102(8) (2011) (establishing a tax based on the federal taxable income
    of the taxpayer for a taxable year).
    15 To the extent that other state courts have held that the federal methodology was incorporated
    into state law, those courts were either interpreting statutes that fully incorporated the federal
    definition of taxable income, see Sch. St. Assocs. v. District of Columbia, 
    764 A.2d 798
    , 806-08 (D.C.
    2001) (en banc); Cooper Indus. v. Ind. Dep’t of State Revenue, 
    673 N.E.2d 1209
    , 1212-14 (Ind. T.C.
    1996); interpreting statutes that specifically authorized a deduction even if none was taken on that
    year’s federal return, see McJunkin Corp. v. W. Va. Dep't of Tax & Revenue, 
    457 S.E.2d 123
    , 126 (W.Va.
    1995); construing a statutory amendment that repealed a limitation on carryback deductions,
    Revenue Cabinet v. Southwire Co., 
    777 S.W.2d 598
    , 600 (Ky. Ct. App. 1989); or deferring to the state
    tax authority’s interpretation of the statute as authorized by state law, see NL Indus. v. N.D. State Tax
    Comm'r, 
    498 N.W.2d 141
    , 146-47 (N.D. 1993). Although the dissent posits that Searle
    Pharmaceuticals, Inc. v. Department of Revenue, 
    512 N.E.2d 1240
    , 1246-51 (Ill. 1987), is analogous to
    the matter before us, the court in that case reviewed a state tax statute to determine whether it
    violated either the Equal Protection Clause or a state constitutional provision regarding tax
    uniformity, and no such issues have been presented here.
    18
    Court of Appeals held that the New York net operating loss deduction taken for
    purposes of a franchise tax on insurance companies could not “exceed the
    amount deducted on the Federal return for the corresponding year” and
    concluded that no independent application of the federal method of
    computation was necessary.        Royal Indem. Co. v. Tax Appeals Tribunal,
    
    549 N.E.2d 1181
    , 1182 (N.Y. 1989). That court reasoned that a deduction “is a
    matter of legislative grace” and that the taxpayer had not carried its burden of
    establishing a right to the deduction based on a statute defining taxable income
    to begin with the income required to be reported to the United States for a
    taxable year, with net operating loss deductions not to exceed that amount. Id.;
    see N.Y. Tax Law § 1503(a), (b)(4)(B) (Consol. LEXIS through 2021 released
    Chapters 1-49, 61-68) (defining taxable income based on the amount that “the
    taxpayer is required to report to the United States treasury department, for the
    taxable year” and providing that a net operating loss deduction may not exceed
    the deduction allowable for federal tax purposes); see also Am. Emps.’ Ins. Co. v.
    State Tax Comm’n, 
    494 N.Y.S.2d 513
    , 514 (N.Y. App. Div. 1985) (holding that a
    franchise tax statute limiting deductions to losses deducted on federal returns
    within a taxable year did not allow for a net operating loss deduction to be taken
    “without having a valid and reciprocal loss claim on [the] Federal income tax
    return for the same taxable year”).
    19
    [¶24] The Supreme Court of Oklahoma similarly held that a statute
    requiring the determination of Oklahoma taxable income by beginning with
    reported federal taxable income “does not create a deduction based on net
    operating loss.” Utica Bankshares Corp. v. Okla. Tax Comm’n, 
    892 P.2d 979
    , 982
    (Okla. 1994). The court held that “tax deductions are a matter of legislative
    grace” and that the statute defining Oklahoma taxable income “does not create
    a federal [net operating loss] deduction.”
    Id. at 983.
    As a result, the court
    affirmed the denial of the taxpayer’s claimed deductions to the extent that they
    exceeded “the amount of federal net operation loss deduction used at the
    federal level for the corresponding tax years.”
    Id. (emphasis added). One
    justice
    concurred to specifically indicate that “the state deduction ‘allowed’ is based
    upon the federal deduction that was ‘allowed’ by the I.R.S. for use on the return.
    The state deduction is not based upon a deduction theoretically available under
    federal law but which was not actually used on the federal return.”
    Id. at 984
    (Summers, J., concurring) (emphasis added).
    [¶25] The Supreme Court of Oklahoma held that because no state
    statutory provision “specifically adopt[ed] all federally allowed deductions,”
    any adjustments to claimed carryover losses pertained only to limit deductions
    actually reflected in that year’s federal return. Getty Oil Co. v. Okla. Tax Comm’n,
    
    563 P.2d 627
    , 630 (Okla. 1977). “If the Legislature had intended to allow a
    20
    carryover deduction in other situations, it could have provided for such an
    adjustment.”
    Id. at 631. [¶26]
    That court applied the same reasoning in a case in which the
    taxpayer’s earlier loss was, as here, taken in a federal tax return filed by a
    federal consolidated group that reported no overall loss for that year. Postal
    Fin. Co. v. Okla. Tax Comm’n, 
    594 P.2d 1205
    , 1205-06 (Okla. 1977).16 The court
    held that the loss could not be claimed for a different tax year for purposes of
    state taxation and that “[t]he rationale of Getty is not destroyed so as not to be
    applicable here because of the consolidated return.”
    Id. [¶27]
    In considering the effect of the previous year’s net operating loss
    on the calculation of taxable income for a taxable year, the Illinois Supreme
    Court affirmed the denial of a deduction where, due to income reported in a
    consolidated federal income tax filing, no net operating loss could be claimed
    on the federal return for that previous year.                     Bodine Elec. Co. v. Allphin,
    
    410 N.E.2d 828
    , 829-33 (Ill. 1980). “Though a given taxpayer may therefore
    16  We did not find this case persuasive for purposes of deciding the issue in Fairchild
    Semiconductor because Oklahoma’s statute—unlike Maine’s—required that the calculation of that
    state’s taxable income begin with the “reported” income on the federal return.

    (quotation marks omitted). Here, however, the parties do not, as in Fairchild
    Semiconductor, dispute or contest the composition of the group that reported its income and losses
    on the federal returns in 2013, and we are focused directly on whether a loss must be allowed in a
    different year for purposes of federal and state taxation. On this issue we find the reasoning in Postal
    Finance Co. v. Oklahoma Tax Commission, 
    594 P.2d 1205
    , 1205-06 (Okla. 1977), persuasive despite
    the differences in the statutory language.

    adopted by the General Assembly is an improper exercise of its taxing
    authority.”
    Id. at 833. [¶28]
    Maine did not tax 2012 nonunitary income in 2013 but simply
    denied a deduction in 2013 because Maine’s statutes did not provide for one.
    Because Maine’s statutes did not call for the application of a carryforward loss
    that would only hypothetically have been allowed under federal law, we must
    next examine the constitutionality of Maine’s taxation scheme.
    B.    Constitutionality
    [¶29] Somerset contends that Maine must consider the extent of unitary
    income on a timeline broader than a single tax year because the manner in
    which Maine taxes a unitary business, see 36 M.R.S. § 5200(4), can result in the
    imposition of higher taxes on a taxpayer because it received nonunitary income
    in another year. Specifically here, it contends that it must be allowed to carry
    the 2012 net operating loss arising from the unitary business forward into the
    2013 Maine tax year because if it had not realized nonunitary business income
    in 2012, it could have carried forward the net operating loss of the unitary
    business for purposes of calculating its 2013 federal taxable income—the
    starting point for determining the income taxable in Maine. Somerset contends
    22
    that, by not allowing the loss carryover on its Maine return for 2013, Maine has
    imposed an unconstitutional indirect tax on nonunitary income from 2012.
    [¶30] “A person challenging the constitutionality of a statute bears a
    heavy burden of proving unconstitutionality, since all acts of the Legislature are
    presumed constitutional.”      Goggin, 
    2018 ME 111
    , ¶ 20, 
    191 A.3d 341
    (alterations omitted) (quotation marks omitted).             “To overcome the
    presumption of constitutionality, the party challenging the statute must
    demonstrate convincingly that the statute and the Constitution conflict. All
    reasonable doubts must be resolved in favor of the constitutionality of the
    statute.”

    [¶31] “The Commerce Clause and the Due Process Clause impose distinct
    but parallel limitations on a State’s power to tax out-of-state activities. The Due
    Process Clause demands that there exist some definite link, some minimum
    connection, between a state and the person, property or transaction it seeks to
    tax, as well as a rational relationship between the tax and the values connected
    with the taxing State. The Commerce Clause forbids the States to levy taxes that
    discriminate against interstate commerce or that burden it by subjecting
    activities to multiple or unfairly apportioned taxation.” MeadWestvaco

    . Although the unitary business principle
    permits Maine to tax income arising out of certain interstate activities, the state
    may not tax extraterritorial, nonunitary income. See Hunt-Wesson, 
    Inc., 528 U.S. at 460-61
    , 464.

    , and the deduction of a net operating loss through a carryover is obtained
    “not as of right, but as of grace,” United States v. Olympic Radio & Television, Inc.,
    
    349 U.S. 232
    , 235 (1955).          Although a state’s imposition of a tax is
    unconstitutional if it impermissibly taxes income “outside its jurisdictional
    reach,” Hunt-Wesson, 
    Inc., 528 U.S. at 468
    , statutes that make “reasonable
    efforts properly to allocate . . . between taxable and tax-exempt income” are
    upheld even if they increase an entity’s tax obligation
    , id. at 466.
    Thus, the
    24
    existence of a tax disadvantage to a particular taxpayer does not necessarily
    establish unconstitutional taxation.17
    [¶33] When the Supreme Court of the United States held, in Hunt-Wesson,
    Inc., that California had imposed a tax that discriminated against interstate
    commerce, it did so because the state had allowed a unitary business to deduct
    its interest expense only to the extent that, for that taxable year, the amount
    exceeded “certain out-of-state income arising from unrelated business activity
    of a discrete business 
    enterprise.” 528 U.S. at 460
    , 466-68. There, the existence
    of the out-of-state income in that tax year directly and explicitly increased the
    taxpayer’s tax burden for that year.
    Id. [¶34]
    Using federal taxable income for a particular tax year as a starting
    point for calculating taxable income in a state does not, however, violate the
    Constitution. See Bodine Elec. 
    Co., 410 N.E.2d at 833
    . And the decision whether
    to allow a carryover of a net operating loss for purposes of state taxation is a
    matter for state legislatures. See Olympic Radio & Television, 
    Inc., 349 U.S. at 17
    The dissent is narrowly focused on the tax disadvantage, stating that the mere fact of a unitary
    net operating loss in 2012 made Somerset eligible to take a carryforward deduction in 2013,
    Dissenting Opinion ¶ 51, regardless of the “taxable income of that taxpayer for that taxable year,”
    here 2013, “under the laws of the United States.” 36 M.R.S. §§ 5102(8), 5200(5) (2011) (emphasis
    added). The dissent’s interpretation—not the Assessor’s position—is in conflict with Maine’s
    statutes. It is undisputed that, due to nonunitary income, TDS Group was not eligible for a net
    operating loss carryforward deduction on its federal return in 2013, and the Constitution does not
    compel us to create such a deduction for purposes of Maine taxation for that year. See Hunt-Wesson,
    Inc. v. Franchise Tax Bd., 
    528 U.S. 458
    , 466 (2000).
    25
    235; see also B.F. Goodrich Co. v. Dubno, 
    490 A.2d 991
    , 995 (Conn. 1985)
    (“Although corporations would be further benefited by greater availability of
    loss carryover deductions, that is a consideration for the legislature, not the
    courts.”); cf. Boulet v. State Tax Assessor, 
    626 A.2d 33
    , 35 (Me. 1993) (“Tax
    credits are a matter of legislative grace that can be broadened, constricted or
    eliminated at any time.”).
    [¶35] The Constitution does not require a state to compare a group’s
    actual federal taxable income in a tax year with the hypothetical federal taxable
    income it might have realized in that year if, for instance, the group had, in
    another year, been reconstituted in a way that excluded all nonunitary income.
    Such a hypothetical group might have behaved differently in the other year—
    or in the taxable year, for that matter—due to the lack of income- and loss-
    sharing with a larger group or due to various other business- and tax-related
    considerations at a state, national, or international level.
    [¶36]    Although the application of Maine’s taxation statutes might
    preclude a group from taking a deduction or receiving a credit for a previous
    year’s net operating loss, that does not mean that the group is being taxed on
    nonunitary income during the tax year for which a carryover is denied.
    See Hunt-Wesson, 
    Inc., 528 U.S. at 466
    (upholding state taxation statutes as long
    as they make a reasonable effort to allocate between taxable and tax-exempt
    26
    income). No part of the nonunitary income reported in 2013 has been taxed,
    and thus there has been no unconstitutional taxation of that nonunitary income.
    Nor has any 2012 nonunitary income been taxed, given that the State of Maine
    imposed no tax on Somerset whatsoever in 2012. In short, the Tax Assessor’s
    determination that the unitary business loss in 2012 could not be deducted
    from the unitary 2013 income does not render any part of the unitary income
    reported in 2013 nonunitary income. Within neither year has there been an
    unfair apportionment or an unconstitutional taxation of extraterritorial
    income. See id.; MeadWestvaco 
    Corp., 553 U.S. at 24
    -25. In each year, the
    application of the Maine statutes reflected a “reasonable effort[] properly to
    allocate . . . between taxable and tax-exempt income.” Hunt-Wesson, 
    Inc., 528 U.S. at 466
    .
    [¶37] In essence, Somerset seeks to create a new deduction in Maine that
    was not authorized by statute and is not required by the Constitution. Because
    Maine statutes do not provide for a carryover of the 2012 net operating loss to
    Maine’s 2013 tax year, and because no such carryover is constitutionally
    required, we affirm the judgment of the Superior Court affirming the decision
    of the State Tax Assessor.
    The entry is:
    Judgment affirmed.
    27
    HORTON, J., dissenting.
    [¶38] I respectfully dissent. In Hunt-Wesson, Inc. v. Franchise Tax Board,
    
    528 U.S. 458
    , 460-65 (2000), the United States Supreme Court held that a state
    cannot limit or deny a tax deduction solely because the taxpayer received
    income that the state cannot constitutionally tax. Today our Court holds the
    opposite. In Fairchild Semiconductor Corp. v. State Tax Assessor, 
    1999 ME 170
    ,
    ¶¶ 6-12, 
    740 A.2d 584
    , we specifically held that the Assessor could not deny a
    unitary business group the ability to take a net operating loss deduction as an
    offset against its Maine taxable income, despite the fact that the unitary
    business did not—and could not—report a net operating loss in its federal
    return because its Maine loss was more than offset by nonunitary income not
    apportionable to Maine. Today the Court holds the opposite.
    [¶39] In this case, it is undisputed that the sole reason that TDS Group
    was unable to take a net operating loss carryforward deduction on its 2013
    federal return was that in 2012 certain members of the unitary business group
    received $149 million in nonunitary income that more than offset the group’s
    $131 million unitary net operating loss for that tax year and thereby caused
    28
    TDS Group’s 2012 federal tax return to reflect net taxable income rather than a
    net operating loss. As was the case in Fairchild, “if the members of the unitary
    group had calculated their taxable income separately at the federal level, the
    loss incurred in the [2012] tax year would have been available to the unitary
    group corporations as [a net operating loss carryforward] deduction in the
    [2013] tax year,”
    id. ¶ 3. [¶40]
    The Assessor acknowledges that the nonunitary income must be
    excluded from TDS Group’s 2012 federal taxable income for purposes of
    calculating Somerset’s 2012 Maine corporate income tax obligation but
    maintains that it cannot be excluded from TDS Group’s 2012 federal taxable
    income for purposes of calculating Somerset’s 2013 Maine corporate income
    tax obligation. In other words, although the Assessor agrees that TDS Group
    incurred a unitary net operating loss in 2012, it disputes Somerset’s claim to a
    net operating loss deduction against 2013 unitary income based on that same
    net operating loss.      The Court’s endorsement of this self-contradictory
    interpretation is contrary to our own interpretation of the Maine tax code and
    the United States Constitution.
    [¶41] In Fairchild, we resolved virtually the same issue as the one
    presented here in deciding that the calculation of a unitary business group’s net
    operating loss deduction for Maine tax purposes should not include income
    29
    earned by corporate affiliates that were not engaged in the unitary business.
    Id. ¶¶ 6-12.
    The unavoidable corollary is that the calculation of the deduction
    for Maine purposes must be based only on the taxpayer’s unitary income.
    See
    id. We phrased the
    issue in Fairchild as being
    whether a [net operating loss] carry-back deduction is available to
    a Maine unitary group for Maine losses when determining “Maine
    net income” . . . despite one not being available at the federal level
    due to the composition of the group filing a consolidated federal
    return.
    Id. ¶ 6
    (emphasis added) (quoting 36 M.R.S.A. § 5102(8) (1990)). “Maine net
    income” was defined as the taxpayer’s
    taxable income . . . for that taxable year under the laws of the United
    States . . . [and t]o the extent that it derives from a unitary
    business . . . [it] shall be determined by apportioning that part of
    the federal taxable income of the entire group which derives from
    the unitary business.
    36 M.R.S.A. § 5102(8) (1990) (emphasis added). We described the difference
    between the taxpayer’s position and the Assessor’s position as being that “[t]he
    Assessor argues that the statute requires a reference to the federal tax return,
    Fairchild to federal law.” Fairchild Semiconductor Corp., 
    1999 ME 170
    , ¶ 6,
    
    740 A.2d 584
    .
    [¶42] In a striking manifestation of jurisprudential déjà vu, this case
    presents essentially the same issue and the same difference in perspective
    between the Assessor and the taxpayer. The Assessor’s disallowance of a net
    30
    operating loss carryforward deduction for Somerset’s 2013 Maine return rests
    totally on the fact that TDS Group did not—and could not due to its receipt of
    nonunitary income—report a net operating loss in its 2012 federal return.18
    Somerset contends that, because federal law would entitle TDS Group to take a
    net operating loss deduction but for the receipt of nontaxable income earned
    outside the unitary business, our decision in Fairchild requires the Assessor to
    allow the deduction.
    [¶43] Our analysis in Fairchild applies so neatly to the facts here that it
    is worth quoting at length:
    The State Tax Code for the tax year in question defined “Maine net
    income” for corporate taxpayers as the taxable income of that
    taxpayer pursuant to the United States Internal Revenue Code. The
    Internal Revenue Code in turn defined “taxable income” as gross
    income minus the deductions allowed pursuant to the [Internal
    Revenue] Code. The deduction at issue in this case for net
    operating losses was allowed by [the Internal Revenue] Code. We
    are asked to determine whether the Legislature intended that the
    income of the Maine unitary group is to be determined by
    calculating the income of the group separately pursuant to [the
    Internal Revenue] Code, or whether the Legislature intended to
    merely adopt the treatment of the unitary group’s income as
    reflected on the federal consolidated return filed by the [fifteen]
    affiliated corporations.
    The plain language of the statute appears clear on this point when
    [it] is read in its entirety. We find reflected in that language an
    intent to determine the Maine “net income” of a unitary group
    18  To be clear, it is undisputed that Somerset’s 2013 Maine tax burden was increased solely
    because some TDS Group members received nonunitary, nontaxable income in 2012.
    31
    separately pursuant to . . . the Internal Revenue Code, as opposed
    to simply adopting the treatment of the unitary group’s income at
    the federal level which may be the result of the group’s
    membership in a federal consolidated group.
    Id. ¶¶ 8-9
    (quoting 26 U.S.C.S. § 63(a) (LEXIS through Pub. L. No. 116-344);
    36 M.R.S.A. § 5102(8) (1990)) (citing 26 U.S.C.S. § 172 (LEXIS through Pub. L.
    No. 116-344)).19
    [¶44] The Maine statute that we found dispositive, 36 M.R.S.A. § 5102(8)
    (1990), was substantively the same as the one that applies for purposes of the
    tax years at issue here. See 36 M.R.S. § 5102(8) (2011). Yet here, rather than
    separating out the unitary business income for 2012 in determining Somerset’s
    entitlement to a net operating loss deduction for 2013, the Assessor has done
    exactly what in Fairchild we said the Assessor should not do: it has “simply
    adopt[ed] the treatment of the unitary group’s income at the federal level,”
    Fairchild Semiconductor Corp., 
    1999 ME 170
    , ¶ 9, 
    740 A.2d 584
    .
    [¶45] There are two differences between Fairchild and this case, but
    neither matters. One difference is that Fairchild involved a net operating loss
    19 In holding that section 5102(8) requires a unitary business group’s entitlement to a net
    operating loss deduction to be determined based only on the income of the unitary business, we also
    explained that net operating loss deductions “counteract the inequity that may result from breaking
    up taxable activity into relatively short periods of time and taxing a discrete income producing period
    without regard to a preceding period of loss.” Fairchild Semiconductor Corp. v. State Tax Assessor,
    
    1999 ME 170
    , ¶ 12, 
    740 A.2d 584
    (quotation marks omitted); see 1 Jerome R. Hellerstein et al., State
    Taxation § 7.16 at 7-120 (3d ed. 2000) (“The [net operating loss] deduction is a response to what can
    be the harsh results of the annual accounting concept when a taxpayer has gains in some years and
    losses in others.”).
    32
    carryback deduction rather than a net operating loss carryforward deduction.
    Id. ¶¶ 1-6.
    However, both types of net operating loss deductions operate
    similarly: a net operating loss incurred in one tax year is netted against income
    in the tax year (or years) in which the deduction is taken. See 26 U.S.C.S.
    § 172(a)-(c). The other difference is that the unitary business group in Fairchild
    was prevented from taking a net operating loss deduction at the federal level
    because the larger affiliated group that filed a consolidated federal return
    included nonunitary companies outside the unitary business group. Fairchild
    Semiconductor Corp., 
    1999 ME 170
    , ¶¶ 2-3, 11, 
    740 A.2d 584
    . Here, TDS Group’s
    federal filing was by a unitary business group, some members of which received
    nonunitary income.     In both instances, income from outside the unitary
    business, i.e., income not apportionable to Maine for purposes of determining
    “Maine net income,” was what prevented the unitary business group from
    taking a federal net operating loss deduction.
    [¶46]     The issue in Fairchild and here is whether the Assessor’s
    determination of a unitary business group’s entitlement to a net operating loss
    deduction must be based exclusively on income earned as a result of the group’s
    unitary business activities, and in Fairchild we answered that question in the
    affirmative.
    Id. ¶¶ 6-12.
    In this case, the Court answers the same question in
    the negative.
    33
    [¶47] In upholding the Assessor’s interpretation, the Court also departs
    from the plain constitutional stricture, explained by the United States Supreme
    Court in Hunt-Wesson, 
    Inc., 528 U.S. at 460-65
    , that a state taxpayer’s receipt of
    nontaxable income cannot increase, directly or indirectly, the tax due to the
    state. In Hunt-Wesson, the Court held that California could not limit the amount
    of an interest expense deduction based on the taxpayer’s receipt of nonunitary
    income.20
    Id. Nothing in Hunt-Wesson
    suggests that the Supreme Court’s
    holding applies only to interest expense deductions and not to net operating
    loss deductions. The Court today emphasizes the point that all deductions are
    matters of grace, not of right, Court’s Opinion ¶¶ 23-24, 32, 34, but that point
    becomes immaterial once a state has granted the right to a deduction, as the
    State of Maine did for tax year 2013.21 The interest deduction at issue in
    Hunt-Wesson was a matter of grace, but the state still could not constitutionally
    limit or deny the deduction based on the taxpayer’s receipt of income that the
    20 The Court concluded that its prior decisions explaining the constitutional prohibition on state
    taxation of extraterritorial nonunitary income “ma[de] clear” that the California statute violated the
    Due Process and Commerce Clauses. Hunt-Wesson, Inc. v. Franchise Tax Bd., 
    528 U.S. 458
    , 463 (2000).
    Although the statute did “not directly impose a tax on nonunitary income,” it “denie[d] the taxpayer
    use of a portion of a deduction from unitary income” because the amount of the deduction was limited
    by the amount of nonunitary income the taxpayer received.
    Id. at 464-65. 21As
    the Court notes, Court’s Opinion ¶ 20, Maine denied corporate taxpayers a net operating loss
    carryforward deduction for the 2009, 2010, and 2011 tax years by requiring that the amount of the
    deduction be added back to federal taxable income in the corporation’s Maine income tax returns for
    those years. See 36 M.R.S. § 5200-A(1)(V) (2011). There was no such addback provision for the 2012
    and 2013 tax years.
    34
    state could not constitutionally tax. Hunt-Wesson, 
    Inc., 528 U.S. at 460-65
    ; see
    Nat’l Life Ins. Co. v. United States, 
    277 U.S. 508
    , 519 (1928) (“One may not be
    subjected to greater burdens upon his taxable property solely because he owns
    some that is free.”). The principle expressed in Hunt-Wesson is not that the
    Constitution requires the states to allow any particular deduction; it is that a
    state cannot constitutionally use the receipt of nontaxable income to limit a
    deduction to which a taxpayer would otherwise be entitled.22                                       See
    Hunt-Wesson, 
    Inc., 528 U.S. at 460-65
    .
    [¶48]       The Court’s ruling today characterizes the outcome in
    Hunt-Wesson as being based on “the existence of the out-of-state income in that
    tax year [that] directly and explicitly increased the taxpayer’s tax burden,”
    Court’s Opinion ¶ 33 (emphasis added), yet nothing in Hunt-Wesson suggests
    that the constitutional prohibition against indirect taxation of nontaxable
    income applies only in the tax year in which the income is received.
    22  According to the Court’s broad holding today, there are no circumstances in which “[u]sing
    federal taxable income for a particular tax year as a starting point for calculating taxable income in a
    state” can “violate the Constitution.” Court’s Opinion ¶ 34. To support that proposition, the Court
    cites only Bodine Elec. Co. v. Allphin, 
    410 N.E.2d 828
    , 833 (Ill. 1980), a case decided twenty years
    before Hunt-Wesson. The Bodine court simply did not analyze the constitutional issue presented here.
    Id. Its bare, unexplained
    statement that it could not “say that [an Illinois statute was] an improper
    exercise of [the state’s] taxing authority,”
    id., was apparently based
    only on a prior holding that
    Illinois did not unconstitutionally delegate legislative powers (to the federal government) when it
    enacted a statute that “adopt[ed], by reference, existing provisions of the [Internal Revenue] Code,”
    Thorpe v. Mahin, 
    250 N.E.2d 633
    , 640 (Ill. 1969).
    35
    [¶49] Likewise, the Court characterizes our holding in Fairchild as
    involving only one tax year:
    We held that Fairchild Semiconductor’s situation as a taxpayer was
    different because it was merely seeking “separate treatment for its
    unitary group the one and only time the federal taxable income of
    the group is calculated.” Fairchild Semiconductor, 
    1999 ME 170
    ,
    ¶ 16, 
    740 A.2d 584
    (emphasis added). That is not the case in the
    matter before us, where the unitary group in essence seeks a
    recalculation of its 2012 federal taxable income for purposes of
    taking a loss in Maine for the 2013 taxable year.
    Court’s Opinion ¶ 22 (emphasis in original).
    [¶50] Fairchild cannot thus be distinguished.23 In Fairchild and this case,
    (1) both unitary business groups sustained a Maine operating loss in one tax
    23  In lieu of following Fairchild, the Court cites cases from other jurisdictions in which courts
    reached the opposite conclusion to the one we reached in Fairchild. Court’s Opinion ¶¶ 23-27, 34;
    compare, e.g., Bodine Elec. 
    Co., 410 N.E.2d at 829-33
    (affirming, based on an interpretation of Illinois’s
    tax statutes, the denial of a net operating loss carryback deduction for a taxpayer whose federal
    consolidated group reported taxable income even though the taxpayer itself incurred a net operating
    loss), and Postal Fin. Co. v. Okla. Tax Comm’n, 
    594 P.2d 1205
    , 1205-07 (Okla. 1977) (examining
    Oklahoma’s statutes), with Fairchild Semiconductor Corp., 
    1999 ME 170
    , ¶¶ 3-12, 17, 
    740 A.2d 584
    ,
    (vacating, based on an interpretation of Maine’s tax statutes, the denial of a net operating loss
    carryback deduction in the exact same circumstances, and specifically rejecting the approach taken
    by the Oklahoma court).
    Meanwhile, other cases from outside Maine are consistent with our conclusion in Fairchild and
    with Somerset’s position in this case. See, e.g., Sch. St. Assocs. v. District of Columbia, 
    764 A.2d 798
    ,
    804, 806-815 (D.C. 2001) (en banc) (holding that a taxpayer was entitled to a net operating loss
    carryback deduction on its D.C. return even though it could not claim the deduction on its
    consolidated federal return); Revenue Cabinet v. Southwire Co., 
    777 S.W.2d 598
    , 599-601 (Ky. Ct. App.
    1989) (explaining that state taxable income must be based on “a figure representing the loss actually
    sustained in” the state and deciding that “the Kentucky legislature intended to allow corporations the
    benefit of income averaging for state tax purposes” because it declined to add back federal net
    operating loss deduction amounts (quotation marks omitted)); Searle Pharms., Inc. v. Dep’t of
    Revenue, 
    512 N.E.2d 1240
    , 1246-51 (Ill. 1987) (concluding that there was no rational basis for
    limiting net operating loss carryback deductions for members of affiliated groups that filed
    consolidated federal returns but not those that filed separate returns); Graham v. State Tax Comm’n,
    
    369 N.Y.S.2d 863
    , 863-65 (N.Y. App. Div. 1975) (vacating, on constitutional grounds, the denial of net
    36
    year that was more than offset by nonunitary income; (2) both unitary business
    groups sought to take a net operating loss deduction in their state tax returns
    in a different tax year; (3) both unitary business groups could have taken a
    federal net operating loss deduction in those other tax years had they reported
    their unitary business income separately on their federal returns; and (4) the
    Assessor disallowed the net operating loss deduction solely because the loss
    had not been reflected in the group’s federal return.24                               See Fairchild
    Semiconductor Corp., 
    1999 ME 170
    , ¶¶ 3-4, 
    740 A.2d 584
    .
    [¶51] In a similar vein, the Court concludes that “[t]he [TDS] group was
    not eligible for a net operating loss carryforward on its 2013 federal tax return
    because it had already accounted for the loss in calculating its federal taxable
    operating loss carryback and carryforward deductions for a taxpayer who incurred an in-state loss
    but reported taxable income on his federal return, which incorporated both in-state and out-of-state
    income).
    24   We summarized the factual background in Fairchild as follows:
    In the 1988 tax year, after adjustments that are not at issue in this case, Fairchild’s
    unitary group had positive income totaling approximately $21 million. The following
    year, the unitary group sustained losses totaling approximately $115 million.
    Because the unitary group filed a consolidated return at the federal level, however,
    these losses were more than offset by the income of the other members of the
    consolidated group. As a result, no [net operating loss] carry-back deduction was
    available to the consolidated group at the federal level. However, if the members of
    the unitary group had calculated their taxable income separately at the federal level,
    the loss incurred in the 1989 tax year would have been available to the unitary group
    corporations as [a net operating loss] carry-back deduction in the 1988 tax year
    pursuant to [the Internal Revenue Code].
    Fairchild Semiconductor Corp., 
    1999 ME 170
    , ¶ 3, 
    740 A.2d 584
    .
    37
    income in 2012.” Court’s Opinion ¶ 19 (emphasis added). But the fact that the
    loss was accounted for in TDS Group’s taxable income for 2012 did not render
    Somerset ineligible to take the net operating loss carryforward deduction in
    2013. In fact, the exact opposite is true: it is because TDS Group incurred a
    unitary net operating loss in 2012 that Somerset became eligible to take a net
    operating loss carryforward deduction against unitary income in 2013. The
    fact that it is the loss that gives rise to the deduction is why the Assessor’s
    position of acknowledging the loss but denying the resulting deduction is
    self-contradictory.
    [¶52] The significance of our ruling in Fairchild and the Supreme Court’s
    ruling in Hunt-Wesson is that nontaxable income must be excluded entirely and
    for all purposes—not partially, not for some purposes, and not only in one tax
    year—from the calculation of the taxpayer’s Maine tax liability. Because the
    Assessor’s determination of Somerset’s entitlement to a net operating loss
    deduction fails to exclude nontaxable income from outside the unitary business,
    I would vacate the judgment and remand for entry of a judgment in favor of
    Somerset in the amount of the requested refund.
