    2                  MOORE V. UNITED STATES
    SUMMARY *
    Tax
    The panel affirmed the district court’s dismissal of an
    action seeking to invalidate the Mandatory Repatriation Tax.
    Taxpayers invested in a controlled foreign corporation
    (CFC), which is a foreign corporation whose ownership or
    voting rights are more than 50% owned by U.S. persons.
    Traditionally, U.S. taxpayers generally did not pay U.S.
    taxes on foreign earnings until those earnings were
    distributed to them. However, when particular categories of
    undistributed earnings were repatriated to the U.S.—through
    a distribution or loan to U.S. shareholders, or an investment
    in U.S. property— U.S. shareholders who owned at least
    10% of a CFC could be taxed on a proportionate share of
    those earnings. The primary method used to tax a CFC’s
    U.S. shareholders on foreign earnings held offshore was a
    provision of the tax code called Subpart F.
    In 2017, the Tax Cuts and Jobs Act (TCJA) created a
    new, one-time tax: the Mandatory Repatriation Tax (MRT).
    Under the MRT’s modified version of Subpart F, U.S.
    persons owning at least 10% of a CFC are taxed on the
    CFC’s profits after 1986, regardless of whether the CFC
    distributed earnings. Additionally, going forward, a CFC’s
    income taxable under subpart F includes current earnings
    from its business.

    has been prepared by court staff for the convenience of the reader.
    MOORE V. UNITED STATES                     3
    Taxpayers challenged the constitutionality of
    Subpart F’s ability to permit taxation of a CFC’s income
    after 1986 through the MRT. The district court dismissed the
    action for failure to state a claim, denied taxpayers’ cross-
    motion for summary judgment, and taxpayers appealed.
    The panel first held that, given the background of the
    government’s power to lay and collect taxes, the MRT is
    consistent with the Apportionment Clause. That clause
    requires that a direct tax must be apportioned so that each
    state pays in proportion to its population. The panel
    acknowledged that the Sixteenth Amendment exempts from
    the apportionment requirement the category of “incomes,
    from whatever source derived.” The panel observed that
    courts have consistently upheld the constitutionality of taxes
    similar to the MRT notwithstanding any difficulty in
    defining income, that the realization of income does not
    determine the tax’s constitutionality, and that there is no
    constitutional ban on Congress disregarding the corporate
    form to facilitate taxation of shareholders’ income. The
    panel explained that Subpart F only applies to U.S. persons
    owning at least 10% of a CFC, the MRT builds upon a
    preexisting liability attributing a CFC’s income to its
    shareholders, and taxpayers were, and continue to be, treated
    as individuals who have some ability to control distribution.
    The panel also held that, assuming without deciding that
    the MRT is retroactive, the MRT does not violate the Fifth
    Amendment’s Due Process Clause. The panel explained that
    the MRT serves the legitimate purpose of preventing CFC
    shareholders who have not yet received distributions from
    obtaining a windfall by never having to pay taxes on their
    offshore earnings that have not yet been distributed. The
    MRT accomplished this legitimate purpose by rational
    means: by accelerating the effective repatriation date of
    4               MOORE V. UNITED STATES
    undistributed CFC earnings to a date following passage of
    the TCJA.

    OPINION
    GOULD, Circuit Judge:
    Charles and Kathleen Moore (the “Moores”) seek to
    invalidate the Mandatory Repatriation Tax (“MRT”) on the
    grounds that it violates the Constitution’s Apportionment
    Clause and Fifth Amendment’s Due Process Clause. The
    Moores, however, have staked out a position for which we
    can find no persuasive authority. We affirm the district
    court’s dismissal of the Moores’ action.
    FACTS AND PROCEDURAL HISTORY
    In 2005, the Moores invested in KisanKraft, a company
    owned by their friend which supplies modern tools to small
    MOORE V. UNITED STATES                    5
    farmers in India. The Moores invested $40,000 in return for
    11% of the common shares. KisanKraft is a controlled
    foreign corporation (“CFC”), which means that it is a foreign
    corporation whose ownership or voting rights are more than
    50% owned by U.S. persons.
    KisanKraft is located in India, and the Moores have
    never participated in its day-to-day operations or
    management. While KisanKraft has turned a profit every
    year, KisanKraft has never distributed any earnings to its
    shareholders. Instead, KisanKraft has reinvested all of its
    earnings as additional shareholder investments in its
    business.
    Traditionally, U.S. taxpayers generally did not pay U.S.
    taxes on foreign earnings until those earnings were
    distributed to them. This system created a strong incentive
    for CFCs to separately incorporate their foreign operations,
    allowing U.S. taxpayers to pay taxes only if and when
    earnings were repatriated to the U.S. By 2015, CFCs had
    accumulated an estimated $2.6 trillion in earnings offshore
    that were not presently subject to U.S. taxation.
    Before 2017, the primary method used to tax a CFC’s
    U.S. shareholders on foreign earnings held offshore was a
    provision of the tax code called Subpart F. See 
    26 U.S.C. § 951
     (2007). Subpart F permitted the taxation of certain
    types of a U.S. person’s CFC earnings when that U.S. person
    owned at least 10% of a CFC’s voting stock. 
    Id.
    Specifically, U.S. shareholders who owned at least 10% of a
    CFC could be taxed on a proportionate share of particular
    categories of its undistributed earnings such as dividends,
    interest, and earnings invested in certain U.S. property. 
    Id.
    § 951(a). Neither Subpart F nor any other provision of the
    tax code permitted the U.S. Government to tax U.S.
    shareholders on the CFC’s active business income
    6               MOORE V. UNITED STATES
    attributable to the CFC’s own business held offshore, such
    as when a CFC manufactures and sells products to a third
    party in a foreign country. Such income was only taxable if
    and when repatriated to the U.S. through a distribution to
    U.S. shareholders, loan to U.S. shareholders, or an
    investment in U.S. property.
    In 2017, Congress passed, and President Trump signed
    into law, the Tax Cuts and Jobs Act (“TCJA”). See 
    131 Stat. 2054
     (2017). The TCJA transformed U.S. corporate taxation
    from a worldwide system, where corporations were
    generally taxed regardless of where their profits were
    derived, toward a territorial system, where corporations are
    generally taxed only on their domestic source profits. As
    part of this change, the TCJA created a new, one-time tax:
    the MRT. The MRT modified Subpart F by classifying CFC
    earnings after 1986 as income taxable in 2017. See
    
    26 U.S.C. §§ 965
    (a), (d) (2017). Under this revised version
    of Subpart F, U.S. persons owning at least 10% of a CFC are
    taxed on the CFC’s profits after 1986 at either 15.5% for
    earnings held in cash or 8% otherwise. 
    Id.
     § 965(c). The
    MRT imposes this tax regardless of whether the CFC
    distributed earnings. It also modified CFC taxes going
    forward: effective January 1, 2018, a CFC’s income taxable
    under Subpart F includes current earnings from its business.
    The TCJA also included tax benefits for shareholders of
    CFCs. When CFCs repatriate untaxed earnings as dividends
    to U.S. shareholders subject to the MRT, those earnings are
    generally not taxed. See 26 U.S.C. § 245A(a). Further, the
    TCJA effectively eliminated any other taxes on a CFC’s
    undistributed earnings and profits before 2018.
    The Government estimates that the MRT will generate
    $340 billion in tax revenue.
    MOORE V. UNITED STATES                    7
    In 2018, the Moores learned about the MRT. According
    to their CPA’s calculations, their tax liability for 2017
    increased by roughly $15,000 because of the MRT. This tax
    liability was based on their pro rata share of KisanKraft’s
    retained earnings of $508,000, subjecting them to an
    additional $132,512 in taxable income.
    The Moores challenged the constitutionality of Subpart
    F’s ability to permit the taxation of a CFC’s income after
    1986 through the MRT. The district court granted the
    Government’s motion to dismiss for failure to state a claim
    and denied the Moores’ cross-motion for summary
    judgment. It held that the MRT taxed income and, although
    it was retroactive, did not violate the Fifth Amendment’s
    Due Process Clause.
    After the district court’s dismissal, the Moores timely
    appealed. We affirm the district court’s order.
    STANDARD OF REVIEW
    We review de novo both the constitutionality of a statute
    and a motion to dismiss for failure to state a claim. United
    States v. Mohamud, 
    843 F.3d 420
    , 432 (9th Cir. 2016)
    (constitutionality of statute); Dougherty v. City of Covina,
    
    654 F.3d 892
    , 897 (9th Cir. 2011) (motion to dismiss for
    failure to state a claim).
    DISCUSSION
    The Moores raise two constitutional challenges to the
    MRT: (1) they contend that it violates the Apportionment
    Clause, and (2) they contend that it violates the Fifth
    Amendment’s Due Process Clause.
    8                MOORE V. UNITED STATES
    Because the MRT imposed on CFCs is a novel concept,
    it is worth dwelling for a moment on some general principles
    that guide us. The federal government is, of course, a
    government of limited and specified powers. See, e.g., Nat’l
    Fed’n of Indep. Bus. v. Sebelius (“NFIB”), 
    567 U.S. 519
    ,
    533–534 (2012). One of those enumerated powers of
    Congress is the power to “lay and collect Taxes, Duties,
    Imposts and Excises, to pay the Debts and provide for the
    common Defence and general Welfare of the United States.”
    U.S. CONST. art. I, § 8, cl. 1. Congress’s power to tax was a
    central force behind the Constitution. See Hylton v. United
    States, 3 U.S. (3 Dall.) 171, 173 (1796) (“The great object of
    the Constitution was, to give Congress a power to lay taxes,
    adequate to the exigencies of government”). Further, it has
    long been established that the federal government may adopt
    laws that are necessary and proper to effectuate its legitimate
    purposes. The Constitution gives Congress the power “[t]o
    make all Laws which shall be necessary and proper for
    carrying into Execution the foregoing Powers, and all other
    Powers vested by this Constitution in the Government of the
    United States, or in any Department or Officer thereof.”
    U.S. CONST. art. I, § 8, cl. 18; see also McCulloch v.
    Maryland, 17 U.S. (4 Wheat.) 316, 323–25 (1819).
    Once the federal government decides to tax something,
    then, subject to any constitutional limitations, its power to
    tax and flexibility as to how to accomplish that must
    necessarily be broad. See, e.g., Agency for Int’l Dev. v. All.
    for Open Soc’y Int’l, Inc., 
    570 U.S. 205
    , 213 (2013) (stating
    that the Spending Clause “provides Congress broad
    discretion to tax”); NFIB, 
    567 U.S. at 573
     (“[T]he breadth of
    Congress’s power to tax is greater than its power to regulate
    commerce”). It is also clear that Congress has sought to
    exercise the full scope of its constitutionally provided power
    to tax. See Comm’r v. Glenshaw Glass Co., 
    348 U.S. 426
    ,
    MOORE V. UNITED STATES                            9
    429 (1955) (noting that the definition of “gross income” to
    be reported by taxpayers “was used by Congress to exert in
    this field ‘the full measure of its taxing power.’” (quoting
    Helvering v. Clifford, 
    309 U.S. 331
    , 334 (1940))). Given
    Congress’s expansive intent in taxing gross income,
    “exclusions from gross income are construed narrowly in
    favor of taxation.” Comm’r v. Dunkin, 
    500 F.3d 1065
    , 1069
    (9th Cir. 2007). It is against this background that we must
    decide whether the MRT offends the U.S. Constitution’s
    Apportionment Clause or its Due Process Clause.
    I. The MRT does not violate the Apportionment Clause
    The Constitution’s Apportionment Clause provides that
    “No Capitation, or other direct, Tax shall be laid, unless in
    Proportion to the Census or Enumeration herein before
    directed to be taken.” U.S. CONST. art. I, § 9, cl. 4. “This
    requirement means that any ‘direct Tax’ must be apportioned
    so that each State pays in proportion to its population.”
    NFIB, 
    567 U.S. at 570
    . The Apportionment Clause
    traditionally applied to only capitations 1 and land taxes. See
    
    id. at 571
     (“[D]irect taxes, within the meaning of the
    Constitution, are only capitation taxes, as expressed in that
    instrument, and taxes on real estate.” (quoting Springer v.
    United States, 
    102 U.S. 586
    , 602 (1881))). While the
    Supreme Court in Pollock v. Farmers’ Loan & Tr. Co., held
    that income from personal property was subject to the
    Apportionment Clause, see 
    158 U.S. 601
    , 618 (1895), the
    Sixteenth Amendment overruled this result, further
    1
    “Capitations are taxes paid by every person, without regard to
    property, profession, or any other circumstance.” NFIB, 
    567 U.S. at 571
    (simplified).
    10               MOORE V. UNITED STATES
    reinforcing the narrow reach of the Apportionment Clause,
    see NFIB, 
    567 U.S. at 571
    .
    The Sixteenth Amendment, ratified in 1913, exempts
    from the apportionment requirement the expansive category
    of “incomes, from whatever source derived.” See U.S.
    CONST. amend. XVI. In United States v. James, we noted
    the difficulty of categorically defining everything that
    constitutes income. See 
    333 F.2d 748
    , 753 (9th Cir. 1964)
    (en banc) (“The courts have given a wide scope to the
    income tax, but have realized that the borderline content of
    ‘income’ must be determined case by case. Essentially the
    concept of income is a flexible one . . . .” (quoting Stanley
    S. Surrey & William C. Warren, The Income Tax Project of
    the American Law Institute: Gross Income, Deductions,
    Accounting, Gains and Losses, Cancellation of
    Indebtedness, 
    66 Harv. L. Rev. 761
    , 770–71 (1953))).
    Despite the difficulty in defining income, courts have
    held consistently that taxes similar to the MRT are
    constitutional. In Eder v. Commissioner of Internal
    Revenue, the Second Circuit held that the inclusion of
    foreign corporate income under a statute predating Subpart
    F was constitutional. See 
    138 F.2d 27
    , 28–29 (2d Cir. 1943).
    Thirty years later, the United States Tax Court upheld pre-
    MRT provisions of Subpart F against constitutional
    challenges, and the decisions were affirmed by the Second
    and Tenth Circuits. See Whitlock’s Est. v. Comm’r, 
    59 T.C. 490
    , 508 (1972), aff’d in part, rev’d in part, 
    494 F.2d 1297
    ,
    1298–99, 1301 (10th Cir. 1974) (upholding constitutionally
    of Subpart F provision taxing “a corporation’s undistributed
    current income to the corporation’s controlling
    stockholders.”); Garlock Inc. v. Comm’r, 
    489 F.2d 197
    , 202
    (2d Cir. 1973) (affirming Tax Court’s ruling that a CFC’s
    Subpart F income was attributable to shareholders even if
    MOORE V. UNITED STATES                      11
    that income had not been distributed and stating that the
    argument it is unconstitutional “borders on the frivolous in
    the light of [the Second Circuit’s] decision in Eder”).
    Whether the taxpayer has realized income does not
    determine whether a tax is constitutional. In Heiner v.
    Mellon, the Supreme Court stated that whether or not a
    “partner’s proportionate share of the net income of the
    partnership” was distributable was not material to whether it
    could be taxed. 
    304 U.S. 271
    , 281 (1938). Similarly in Eder,
    the Second Circuit noted that “[i]n a variety of circumstances
    it has been held that the fact that the distribution of income
    is prevented by operation of law, or by agreement among
    private parties, is no bar to its taxability.” 
    138 F.2d at
    28
    (citing Heiner, 
    304 U.S. at 281
    ; Helvering v. Enright’s Est.,
    
    312 U.S. 636
    , 641 (1941)). And, the Supreme Court has
    made clear that realization of income is not a constitutional
    requirement. See Helvering v. Horst, 
    311 U.S. 112
    , 116
    (1940) (“[T]he rule that income is not taxable until realized
    . . . . [is] founded on administrative convenience . . . and [is]
    not one of exemption from taxation where the enjoyment is
    consummated by some event other than the taxpayer’s
    personal receipt of money or property.”); see also Helvering
    v. Griffiths, 
    318 U.S. 371
    , 393–94 (1943) (explaining that
    Horst “undermined . . . the original theoretical bases” of a
    constitutional realization requirement).
    What constitutes a taxable gain is also broadly construed.
    In Helvering v. Bruun, the Supreme Court determined that a
    lessee’s improvements to the land were a taxable gain when
    the lessor regained possession of the land. 
    309 U.S. 461
    , 469
    (1940). The Court instructed that a taxable “[g]ain may
    occur as a result of exchange of property, payment of the
    taxpayer’s indebtedness, relief from liability, or profit
    realized from the completion of a transaction.” 
    Id.
     We
    12               MOORE V. UNITED STATES
    applied this precedent nearly half a century later, holding
    that the cancellation of indebtedness was a taxable gain. See
    Vukasovich, Inc. v. Comm’r, 
    790 F.2d 1409
    , 1415 (9th Cir.
    1986) (“We have no doubt that an increase in wealth from
    the cancellation of indebtedness is taxable where the
    taxpayer received something of value in exchange for the
    indebtedness.”).
    Further, there is no blanket constitutional ban on
    Congress disregarding the corporate form to facilitate
    taxation of shareholders’ income. In other words, there is no
    constitutional prohibition against Congress attributing a
    corporation’s income pro-rata to its shareholders. See, e.g.,
    Dougherty v. Comm’r, 
    60 T.C. 917
    , 928 (1973) (noting that
    nothing “prevent[s] Congress from bypassing the corporate
    entity in determining the incidence of Federal income
    taxation.”). And here, there is no dispute that KisanKraft
    actually earned significant income, though all tax that the
    Moores’ owed the U.S. Government on their pro-rata share
    of KisanKraft was deferred until the MRT went into effect
    in 2017.
    Given this background, we hold that the revised Subpart
    F is consistent with the Apportionment Clause. As modified
    by the MRT, Subpart F only applies to U.S. persons owning
    at least 10% of a CFC. The MRT builds upon these U.S.
    persons’ preexisting tax liability attributing a CFC’s income
    to its shareholders. Before the MRT, U.S. persons owning
    at least 10% of a CFC were already subject to certain taxes
    on the CFC’s income. Minority owners like the Moores
    were, and after the passage of the MRT continue to be,
    treated as individuals who have some ability to control
    distribution. See 
    id.
     (“In subpart F, Congress has singled out
    a particular class of taxpayers . . . whose degree of control
    over their foreign corporation allows them to treat the
    MOORE V. UNITED STATES                       13
    corporation’s undistributed earnings as they see fit.”).
    Further, the MRT applies to taxable gains. Clearly,
    KisanKraft earned significant income, and the MRT assigns
    only a pro-rata share of that income to the Moores.
    Relying on Eisner v. Macomber, 
    252 U.S. 189
    , 219
    (1920), and Glenshaw Glass, 
    348 U.S. at 431
    , the Moores
    argue that the MRT is an unapportioned direct tax.
    Specifically, the Moores argue that Macomber and
    Glenshaw Glass require income to be realized before it can
    be taxed. They urge us to adopt and apply the purported
    definition of income used in Glenshaw Glass, which would
    require “[1] undeniable accessions to wealth, [2] clearly
    realized, and [3] over which the taxpayers have complete
    dominion.” 
    348 U.S. at 431
    . The Moores’ reliance on these
    cases is misplaced: the Supreme Court, our court, and other
    courts have narrowly interpreted Macomber and Glenshaw
    Glass, and Glenshaw Glass’s definition is not applicable
    here.
    First, Macomber and Glenshaw Glass themselves
    foreclose the Moores’ arguments. In Macomber, the Court
    was clear that it was only providing a definition of what
    “[i]ncome may be defined as,” 
    252 U.S. at 207
    , not a
    universal definition. Glenshaw Glass reiterated the limited
    scope of Macomber’s definition of income by emphasizing
    that, while the definition “served a useful purpose . . . , it was
    not meant to provide a touchstone to all future gross income
    questions.” 
    348 U.S. at 431
    . Glenshaw Glass similarly
    cabined the definition of income it used, prefacing its
    definition of income by saying “[h]ere we have instances
    of,” signaling that the Court was focused on the specific facts
    before it. See 
    id.
     The Court in Glenshaw Glass never stated
    or suggested that the definition it used was a universal (or
    even broadly applicable) test. Realization was also not even
    14              MOORE V. UNITED STATES
    disputed in Glenshaw Glass, explaining why the Court did
    not make more than a passing reference to realization. See
    
    id.
     at 428–29 (discussing how both taxpayers had realized
    damages and simply disputed their need to pay taxes on
    them).
    Second, the Supreme Court has subsequently made clear
    that Macomber and Glenshaw Glass do not provide a
    universal definition of income. In Horst, the Supreme Court
    explained that the concept of realization is “founded on
    administrative convenience” and does not mean that a
    taxpayer can “escape taxation because he did not actually
    receive the money.” 
    311 U.S. at 116
    . In Griffiths, the
    Supreme Court explicitly stated that this holding from Horst
    “undermined . . . the original theoretical bases of the
    decision in Eisner v. Macomber.” 
    318 U.S. at 394
    . The
    Supreme Court recently reiterated Horst’s statement that
    “the concept of realization is founded on administrative
    convenience,” Cottage Savings, 499 U.S. at 559 (quoting
    Horst, 
    311 U.S. at 116
    ), without adopting the test from
    Glenshaw Glass that the Moores urge upon us; in fact, the
    Court did not even cite to Glenshaw Glass.
    Third, we have not adopted the definition of income the
    Moores advocate. In James, we cited a passage from
    Glenshaw Glass that included the definition of income the
    Moores favor, but we never adopted it then or later. See
    
    333 F.2d at 752
     (noting also that “insofar as [Macomber]
    purported to offer a comprehensive definition of the term
    income as used in the Sixteenth Amendment, it has been
    discarded.”). Instead, we stated that there was no set
    definition of income under the Sixteenth Amendment. See
    
    id.
     at 752–53. Similarly, in Comm’r v. Fender Sales, Inc.,
    we did not cite to Glenshaw Glass or adopt the Moores’
    preferred definition when determining whether a tax was
    MOORE V. UNITED STATES                     15
    constitutional under the Sixteenth Amendment.             See
    
    338 F.2d 924
    , 927 (9th Cir. 1964) (noting also that “[i]n this
    context, Eisner v. Macomber . . . is not even apposite, let
    alone controlling.”).
    Finally, although it does not control our analysis, holding
    that Subpart F is unconstitutional under the Apportionment
    Clause would also call into question the constitutionality of
    many other tax provisions that have long been on the books.
    See Bruce Ackerman, Taxation and the Constitution,
    
    99 Colum. L. Rev. 1
    , 52 (1999). We decline to do so today.
    II. The MRT does not violate the Fifth Amendment’s
    Due Process Clause
    Retroactive legislation may violate the Fifth
    Amendment’s Due Process Clause. See Landgraf v. USI
    Film Prods., 
    511 U.S. 244
    , 266 (1994). “[T]he presumption
    against retroactive legislation is deeply rooted in our
    jurisprudence, and embodies a legal doctrine centuries older
    than our Republic.” 
    Id. at 265
    . We assume, without
    deciding, that the MRT is retroactive.
    While there is a presumption against retroactive laws,
    retroactive tax legislation is often constitutional. See, e.g.,
    United States v. Carlton, 
    512 U.S. 26
    , 30 (1994) (“[The
    Supreme Court] repeatedly has upheld retroactive tax
    legislation against a due process challenge.”); United States
    v. Hemme, 
    476 U.S. 558
    , 568 (1986) (“[The Supreme Court]
    has . . . made clear that some retrospective effect is not
    necessarily fatal to a revenue law.”). To analyze a due
    process challenge to retroactive tax legislation, we use the
    “deferential” standard of “whether [the] retroactive
    application itself serves a legitimate purpose by rational
    means.” Quarty v. United States, 
    170 F.3d 961
    , 965 (9th Cir.
    1999) (citing Carlton, 
    512 U.S. at
    30–31).
    16                 MOORE V. UNITED STATES
    The MRT passes muster under Carlton. The TCJA was
    a significant change in the U.S. tax code, shifting from a
    worldwide toward a territorial tax system, at least in part
    because of companies offshoring roughly $2.6 trillion in
    profits. The MRT eliminated other taxes on CFCs’
    undistributed earnings before 2018. So, if the MRT did not
    tax the undistributed earnings, shareholders would have been
    able to avoid taxation indefinitely on pre-2018 earnings. The
    MRT, then, serves a legitimate purpose: it prevents CFC
    shareholders who had not yet received distributions from
    obtaining a windfall by never having to pay taxes on their
    offshore earnings that have not yet been distributed.
    The MRT accomplishes this legitimate purpose by
    rational means.       The MRT accelerates the effective
    repatriation date of undistributed CFC earnings to a date
    following passage of the TCJA. Having a single date of
    repatriation is a rational administrative solution. The 30-
    year repatriation period also coincided with additional IRS
    reporting requirements, simplifying the calculation of taxes
    by both taxpayers and the IRS. 2
    The Moores’ counterarguments are unpersuasive.
    Although the Moores may have expected their tax to remain
    deferred, their “reliance alone is insufficient to establish a
    constitutional violation. Tax legislation is not a promise, and
    a taxpayer has no vested right in the Internal Revenue Code.”
    Carlton, 
    512 U.S. at 33
    . Further, while the MRT’s
    retroactive period is long, it does not decide the analysis.
    2
    The MRT also provided a lower tax rate than many shareholders
    would likely have paid otherwise: the MRT taxes CFC earnings at either
    8% or 15.5%. And, taxpayers may also elect to pay the MRT in
    installments over an eight-year period. See Section 965 Transition Tax,
    The Internal Revenue Service, https://www.irs.gov/businesses/section-
    965-transition-tax (last visited May 30, 2022).
    MOORE V. UNITED STATES                     17
    The Moores cannot cite a bright-line rule regarding how long
    ago a retroactive tax can apply because courts deferentially
    review tax legislation’s purpose on a case-by-case basis. See
    Quarty, 
    170 F.3d at 965
    . Moreover, courts that have
    considered the retroactive nature of tax legislation often only
    view the period of retroactivity as one, non-dispositive
    consideration. See, e.g., GPX Int’l Tire Corp. v. United
    States, 
    780 F.3d 1136
    , 1142 (Fed. Cir. 2015) (discussing five
    “considerations,” of which retroactivity was only one).
    Nor is the MRT a “wholly new tax,” a label applied to
    unconstitutionally retroactive taxes by early cases “under an
    approach that has long since been discarded.” Quarty,
    
    170 F.3d at 966
     (quoting Carlton, 
    512 U.S. at 34
    ). We have
    very narrowly interpreted what qualifies as a “wholly new
    tax,” determining that a “a new tax is imposed only when the
    taxpayer has ‘no reason to suppose that any transactions of
    the sort will be taxed at all.’” See Quarty, 
    170 F.3d at 967
    (quoting United States v. Darusmont, 
    449 U.S. 292
    , 298
    (1981)). The MRT is not a “wholly new tax” because prior
    to the MRT, U.S. shareholders were taxed on CFC earnings
    when they were distributed. The Moores had reason to
    expect that such transactions would eventually be taxed. See
    
    id.
     This is especially true because as 11% shareholders of
    KisanKraft, the Moores were already subject to certain pre-
    MRT taxes that applied to shareholders who owned at least
    10% of a CFC regardless of whether earnings were
    distributed. See 
    26 U.S.C. § 951
    (a)(1) (2007).
    CONCLUSION
    For the above reasons, we AFFIRM the district court’s
    grant of the Government’s motion to dismiss and denial of
    the Moores’ cross-motion for summary judgment.
