    SUMMARY **
    Tax
    The panel reversed a decision by the full Tax Court in
    favor of the Commissioner on a petition for redetermination
    of federal excise tax deficiency, in a case involving the use
    of a Foreign Sales Corporation to reduce the tax paid on
    income that was then distributed as dividends to Roth
    Individual Retirement Accounts.
    Appellants established a FSC under since-repealed
    provisions of Internal Revenue Code §§ 921–927 (the FSC
    statute). Under the FSC statute, a corporation with foreign
    trade income could establish a related FSC as a shell
    corporation and then effectively cycle a portion of that
    income through the FSC where it would be taxed at lower
    rates. As a result, the FSC’s taxable income was generated
    through related-party transactions that lacked meaningful
    economic substance. The FSC taxation rules thus reflected a
    departure from the normal principle that taxation is based on
    economic substance rather than on legal form.
    Appellants made their Roth IRAs formal shareholders of
    their FSC. Appellants’ export corporation paid commissions
    into the FSC, and the FSC’s after-tax income was returned
    as dividends and distributed to appellants’ IRAs rather than
    to their export corporation. As a result, no tax was paid when
    the money was received into the Roth IRAs, and no tax
    would be paid on qualified withdrawals from the Roth IRAs.

    The Commissioner challenged this scheme, asking the
    Tax Court to recharacterize the entire scheme under the
    doctrine of substance over form. The Tax Court held that,
    under substance-over-form principles, appellants—not the
    Roth IRAs—were the real owners of the FSC. This meant
    that appellants should be deemed to have received the
    dividends, their contributions to the Roth IRAs exceeded the
    statutory limits for such contributions, and appellants were
    consequently liable for excise taxes on the excess
    contributions.
    The panel concluded that, due to the unusual statutory
    provisions at issue here, the Tax Court erred by invoking
    substance-over-form principles to effectively reverse
    congressional judgment and to disallow what the statute
    plainly allowed. The panel joined three other circuits that
    have similarly disallowed the invocation of substance-over-
    form principles to undo the congressionally authorized
    separation of substance and form that is involved in an entity
    similar to the FSC at issue here.

    OPINION
    COLLINS, Circuit Judge:
    Angelo, Mary, and Celia Mazzei appeal the Tax Court’s
    ruling that they are liable for excise taxes for having made
    excess contributions to their Roth Individual Retirement
    Accounts (“IRAs”).           Invoking substance-over-form
    principles, the Commissioner insists that the dividends that
    the Mazzeis’ Roth IRAs received from a specific corporation
    were actually contributions from the Mazzeis, because the
    Commissioner deemed the Mazzeis, rather than the IRAs, to
    be the real owners of that corporation. Over the vigorous
    dissent of four judges, the full Tax Court sided with the
    Commissioner. Because we conclude that the unusual
    statutory provisions at issue here expressly elevated form
    over substance in the relevant respects, the Tax Court erred
    by invoking substance-over-form principles to effectively
    reverse that congressional judgment and to disallow what the
    statute plainly allowed.
    The underlying dispute arises from the Mazzeis’
    establishment of a Foreign Sales Corporation (“FSC”) under
    the since-repealed provisions of Internal Revenue Code
    §§ 921–927 (“the FSC statute”). As we explain in detail
    below, FSCs were an unusual type of corporation that
    Congress first authorized in 1984 to promote exports and
    that the World Trade Organization held in 2000 constituted
    an impermissible trade subsidy. Under the FSC statute, a
    corporation with foreign trade income could establish a
    related FSC as a shell corporation and then effectively cycle
    a portion of that income through the FSC where it would be
    taxed at lower rates. Specifically, the export corporation
    could pay tax-deductible “commissions” to the FSC that did
    not correspond to any actual services provided by the FSC
    but that were instead determined according to complex
    MAZZEI V. CIR                          5
    statutory formulas. The FSC would pay a modest tax on the
    resulting income, and the FSC would then return the
    remaining income back to the export corporation (or a
    related entity) as dividends, usually tax-free. As a result, the
    FSC’s taxable income was largely generated through
    related-party transactions that lacked meaningful economic
    substance, and the FSC taxation rules thus reflected a sharp
    departure from the normal principle that taxation is based on
    economic substance rather than on legal form.
    The Mazzeis (and many others) took this one step further
    by having their Roth IRAs be the formal shareholders of the
    FSC. This meant that, when the FSC’s after-tax income was
    being returned as dividends, it was distributed to the IRAs
    rather than to the export corporation that had paid the
    commissions into the FSC. As a result, no tax was paid when
    the money was received into the Roth IRAs, no tax would be
    paid on the growth of those funds over time, and no tax
    would be paid if and when the Mazzeis made qualified
    withdrawals from the Roth IRAs. The Commissioner
    thought that this arrangement was too good to be true, and
    he challenged what the Mazzeis had done here, as well as
    similar arrangements involving other taxpayers invoking
    related strategies. The Tax Court declined to adopt the
    Commissioner’s broad effort to recharacterize the relevant
    transactions as a whole, and the court instead held only that,
    under substance-over-form principles, the Mazzeis rather
    than the Roth IRAs were the real owners of the FSC. That
    meant that the Mazzeis should be deemed to have received
    the dividends. And that meant, in turn, that the Roth IRAs
    received those funds as contributions from the Mazzeis, and
    these were well in excess of the statutory limits on such
    contributions. As a result, the Tax Court concluded, the
    Mazzeis were liable for excise taxes on the excess
    contributions.
    6                      MAZZEI V. CIR
    Three circuits have addressed comparable questions in
    the context of a similar type of corporation allowed by the
    Internal Revenue Code, namely, a Domestic International
    Sales Corporation (“DISC”). All three courts reversed the
    Tax Court and disallowed the invocation of substance-over-
    form principles to undo the congressionally authorized
    separation of substance and form that is involved in a DISC.
    We reach a similar conclusion as to FSCs here, and we
    therefore reverse the judgment of the Tax Court.
    I
    This is a case in which the details matter a great deal, and
    so we first set forth the complex legal backdrop and then
    explain the specific facts of this case.
    A
    The legal context for this dispute involves three different
    entities that are (or were) specially authorized by the Internal
    Revenue Code, namely, Roth IRAs, FSCs, and DISCs.
    Although the Mazzeis did not use a DISC, the FSC regime
    was expressly modeled after the DISC system, and so an
    understanding of the latter will help to elucidate the
    distinctive features of the former. Moreover, the only circuit
    decisions addressing comparable issues arose in the DISC
    context, thereby underscoring the importance of
    understanding both types of corporations. Accordingly, we
    briefly review the key features of the Roth IRA, DISC, and
    FSC.
    1
    Congress first authorized tax-advantaged IRAs in 1974,
    initially as a means of providing retirement assistance to
    those who lacked coverage under a pension plan. See
    MAZZEI V. CIR                        7
    Employee Retirement Income Security Act of 1974, Pub. L.
    93-406, § 2002, 
    88 Stat. 829
    , 958–64. Congress has
    substantially expanded the availability of IRAs since then,
    and it has made numerous changes to the tax treatment of
    such accounts. In particular, Congress in 1997 authorized a
    new alternative type of IRA called a “Roth IRA.” See
    Taxpayer Relief Act of 1997, Pub. L. No. 105-34, § 302(a),
    
    111 Stat. 788
    , 825.
    The tax treatment of earnings in a Roth IRA are generally
    the same as for a traditional IRA: earnings grow tax-free,
    except that they remain “subject to the taxes imposed by
    section 511” concerning unrelated business income. I.R.C.
    § 408(e)(1). But the tax treatment of contributions and
    withdrawals differs sharply for a Roth IRA versus a
    traditional IRA. With a traditional IRA, authorized
    contributions into the account are deductible from taxable
    income, see id. § 219(a), but subsequent authorized
    withdrawals are generally subject to taxation as ordinary
    income, see id. § 408(d)(1). For a Roth IRA, these rules are
    reversed: no deduction is allowed for a contribution into a
    Roth IRA, see id. § 408A(c)(1), but distributions from a
    Roth IRA are not taxable, id. § 408A(d)(1). Loosely
    speaking, money is taxed only before going into a Roth IRA,
    and money is taxed only on the way out of a traditional IRA.
    Given the significant tax advantages of a Roth IRA, in
    which funds grow tax free and then remain free from
    taxation upon authorized distribution, Congress has
    established a statutory formula that strictly limits
    contributions to Roth IRAs. See I.R.C. § 408A(c). Under
    that formula, as a taxpayer’s income increases, the
    contribution limit generally decreases. Id. To enforce such
    contribution limits to Roth IRAs (as well as other tax-
    favored vehicles), Congress has imposed a 6 percent tax on
    8                      MAZZEI V. CIR
    excess contributions, subject to the proviso that the amount
    of the tax cannot exceed 6 percent of the value of the
    account. Id. § 4973(a), (f). Moreover, a comparable excise
    tax is imposed each subsequent year unless and until an
    amount corresponding to the excess contribution is properly
    removed from the Roth IRA. Id. § 4973(b)(2).
    2
    To promote exports of domestic goods, Congress in 1971
    authorized the creation of DISCs, which are governed by
    special rules that allow companies to reduce the taxes they
    pay on export income. See Revenue Act of 1971, Pub. L.
    No. 92-178, §§ 501–507, 
    85 Stat. 497
    , 535–53. The DISC
    system has been amended over the intervening years, and we
    briefly sketch its key features in their present form.
    The central feature of the DISC system is a special
    statutory exception for DISCs from the normal rules that
    govern allocation of income between “two or more
    organizations, trades, or businesses . . . owned or controlled
    directly or indirectly by the same interests.” I.R.C. § 482.
    Under this statutory exception, the shareholders of a
    corporation with products to export can create a commonly
    controlled DISC and then “sell” those products “to the DISC
    at a hypothetical ‘transfer price’ that produce[s] a profit for
    both seller [i.e., the export corporation] and buyer [i.e., the
    DISC] when the product [is] resold to the foreign customer.”
    Boeing Co. v. United States, 
    537 U.S. 437
    , 441 (2003)
    (emphasis added). This hypothetical “transfer price” for the
    sale of goods between the two commonly controlled entities
    is not based on any underlying economic reality, but is
    instead set artificially in accordance with a complex
    statutory formula. I.R.C. § 994(a) (explicitly stating that, in
    the case of a “sale of export property” to the DISC, income
    can be allocated to the DISC in accordance with the statutory
    MAZZEI V. CIR                         9
    formula “regardless of the sales price actually charged”).
    The details of that statutory formula are not relevant here.
    What matters is that the ultimate consequence of these rules
    is effectively to reallocate a portion of the company’s export
    income to the DISC, where that income would not be subject
    to corporate income tax. See id. § 991.
    Although the statute itself articulates these special rules
    only in the context of the “sale of export property to a DISC”
    by a commonly controlled entity, I.R.C. § 994(a) (emphasis
    added), the statute also instructs the Secretary of the
    Treasury to issue regulations establishing comparable rules
    applicable in “the case of commissions, rentals, and other
    income” between a DISC and a commonly controlled entity,
    id. § 994(b) (emphasis added). The Secretary has issued
    such regulations, which allow an export corporation to
    obtain comparable advantages by paying a hypothetical
    “commission” to a commonly controlled DISC for the
    latter’s provision of export services. See 
    26 C.F.R. § 1.994
    -
    1(d)(2). These regulations set forth specific instructions for
    calculating the “maximum commission the DISC may
    charge” the export corporation and the “amount of the
    income that may be earned by the DISC in any year” in
    connection with “qualified export receipts.” 
    Id.
     § 1.994-
    1(d)(2)(i)–(ii). Once again, the details of these formulas are
    not relevant for present purposes. The key point is that,
    under these special rules, an export corporation may pay a
    tax-deductible “commission” to the DISC in an amount that,
    as a general matter, is explicitly divorced from the value of
    any services actually provided by the DISC. See id. § 1.994-
    1(a)(2) (application of these rules “does not depend on the
    extent to which the DISC performs substantial economic
    functions (except with respect to export promotion
    expenses)”); see also id. § 1.993-1(k)(1) (to earn such
    commissions, “such DISC need not have employees or
    10                        MAZZEI V. CIR
    perform any specific function”). 1 The DISC, in turn, is
    generally exempt from any tax on its income from these
    commissions. I.R.C. § 991.
    As a result of these unique rules, neither the export
    corporation nor the DISC pays any income tax on the
    applicable income that is attributable to the corporation’s
    qualified export receipts but that was effectively allocated to
    the DISC by way of (as the case may be) the hypothetically
    priced sale or the artificially determined “commissions.”
    Income tax is generally only paid when the DISC distributes
    its received commissions as dividends to the DISC’s
    shareholders, either because the DISC actually pays out the
    dividends, see I.R.C. §§ 1(h)(11), 246(d), or because,
    according to a detailed statutory formula, the shareholder is
    deemed to have “received a distribution taxable as a
    dividend with respect to his [or her] stock,” id. § 995(b)(1).
    1
    The regulation gives the following stark example to illustrate just
    how much of a shell a DISC can be and still earn commissions:
    P Corporation forms S Corporation as a wholly-owned
    subsidiary. S qualifies as a DISC for its taxable year.
    S has no employees on its payroll. S is granted a sales
    franchise with respect to specified exports of P and
    will receive commissions with respect to such exports.
    Such exports are of a type which will produce gross
    receipts for S which are qualified export receipts as
    defined in paragraph (b) of this section. P’s sales force
    will solicit orders in the name of P. Billings and
    collections are handled directly by P. Under these
    facts, the commissions paid to S for such taxable year
    with respect to the specified exports shall be treated
    for Federal income tax purposes as the income of S,
    and the amount of income allocable to S is determined
    under section 994 of the Code.
    
    26 C.F.R. § 1.993-1
    (k)(3) (example 2).
    MAZZEI V. CIR                             11
    The “net effect” of these complex rules is thus to allow an
    export company to ultimately transfer a portion of its export
    revenue to the DISC’s shareholders (who are often either the
    export company or its shareholders) in the form of dividends,
    without having it ever being taxed “as corporate income.”
    Summa Holdings, Inc. v. Commissioner, 
    848 F.3d 779
    , 782
    (6th Cir. 2017).
    The Internal Revenue Code explicitly contemplates that
    tax-exempt entities—a category that now includes Roth
    IRAs—may own shares of a DISC. It does so by
    establishing a special rule that applies when the “shareholder
    in a DISC” is an “organization . . . subject to tax under
    section 511.” See I.R.C. § 995(g). As noted earlier, that
    category includes traditional IRAs and, since their
    authorization in 1997, Roth IRAs. See id. § 408(e)(1)
    (stating that, although IRAs are generally exempt from
    income taxation, they are “subject to the taxes imposed by
    section 511”); see also supra at 7. Under this special rule,
    when an IRA owns the shares of a DISC, any dividends
    distributed, or deemed distributed, to the IRA are generally
    “treated as derived from the conduct of an unrelated trade or
    business,” I.R.C. § 995(g), and therefore subject to taxation
    under § 511. That unrelated-business-income tax rate is
    “equal to the corporate rate,” which is generally higher than
    the “dividend rate” that would apply to DISC dividends paid
    to an individual shareholder of a DISC. See Benenson v.
    Commissioner, 
    910 F.3d 690
    , 694 (2d Cir. 2018). 2 As a
    result, when a traditional IRA holds shares in a DISC, the
    “DISC dividends are subject to high unrelated business
    income tax when they go into [that] traditional IRA and, like
    2
    When a corporation that is subject to income tax is the owner of a
    DISC’s shares, it must generally pay income tax, at the corporate rate,
    on dividends received from a DISC. I.R.C. § 246(d).
    12                    MAZZEI V. CIR
    all withdrawals from [a] traditional IRA, are subject to
    personal income tax when taken out.” Id. (emphasis added)
    (citing Summa Holdings, 848 F.3d at 783). That makes a
    traditional IRA a singularly unattractive vehicle for holding
    DISC shares. Id. And that is no accident—Congress enacted
    the special taxation rule in § 995(g) in 1989 precisely
    because, under the prior rule in which “tax-exempt entities
    like IRAs paid nothing on DISC dividends,” export
    companies were “shield[ing] active business income from
    taxation by assigning DISC stock to controlled tax-exempt
    entities like pension and profit-sharing plans.” Summa
    Holdings, 848 F.3d at 782.
    But the situation with a Roth IRA is somewhat different.
    To be sure, a Roth IRA, like a traditional IRA, generally
    must still pay unrelated-business-income tax on dividends
    received from a DISC. I.R.C. §§ 511, 995(g). However,
    once those monies are safely in a Roth IRA, they can
    thereafter grow tax-free and—unlike a traditional IRA—
    they are not subject to income tax when they are properly
    distributed out of the Roth IRA. For some taxpayers, that
    can make a Roth IRA an attractive vehicle for holding DISC
    shares.
    3
    “Soon after its enactment, the DISC statute became ‘the
    subject of an ongoing dispute between the United States and
    certain other signatories of the General Agreement on Tariffs
    and Trade (GATT)’ regarding whether the DISC provisions
    were impermissible subsidies that violated our treaty
    obligations.” Boeing Co., 
    537 U.S. at 442
     (citation omitted).
    As a result, Congress in 1984 authorized a distinct but
    similar entity known as a “Foreign Sales Corporation” or
    “FSC.” See Deficit Reduction Act of 1984, Pub. L. No. 98-
    369, §§ 801–805, 
    98 Stat. 494
    , 985–1003. The hope was that
    MAZZEI V. CIR                               13
    the FSC system, which would serve as an alternative to a
    modified DISC scheme, would ameliorate such international
    controversy. Boeing Co., 
    537 U.S. at 442
    . That hope proved
    illusory, and the FSC regime itself was determined by the
    World Trade Organization in March 2000 to be “an
    impermissible subsidy.” Ford Motor Co. v. United States,
    
    908 F.3d 805
    , 808 (Fed. Cir. 2018). Congress promptly
    repealed the FSC provisions in November 2000, but the
    repeal statute contained transition provisions that allowed
    for certain existing FSCs to continue for a specified time.
    See FSC Repeal and Extraterritorial Income Exclusion Act
    of 2000, Pub. L. No. 106-519, 
    114 Stat. 2423
    . 3 Throughout
    all of this, Congress did not eliminate the alternative DISC
    regime, whose current form we described earlier. See supra
    at 8–12.
    The statutory provisions governing FSCs were set forth
    in former §§ 921–927 of the Internal Revenue Code. 4 In
    3
    Specifically, § 5 of the repeal statute specified that FSCs could not
    be formed after September 30, 2000, but that for active FSCs in existence
    as of that date, the repeal generally would not apply to transactions
    involving the FSC (1) that occurred before January 1, 2002; or (2) that
    occurred after December 31, 2001, pursuant to certain binding contracts
    in effect on September 30, 2000. See Pub. L. No. 106-519, § 5(b)(1),
    (c), 114 Stat. at 2433. (The second of these transitional rules, concerning
    transactions pursuant to certain binding contracts, was itself later
    repealed for taxable years beginning after May 17, 2006. See Tax
    Increase Prevention and Reconciliation Act of 2005, Pub. L. No. 109-
    222, § 513(a),

    contrast to DISCs, which are domestic corporations, a FSC 5
    generally must be organized under the laws of certain
    foreign countries or under the laws applicable to a U.S.
    possession. I.R.C. § 922(a)(1)(A). The centerpiece of the
    FSC system was similar to that of the DISC system, viz., an
    explicit statutory exception from the ordinary rules that
    govern allocation of income between “two or more
    organizations, trades, or businesses . . . owned or controlled
    directly or indirectly by the same interests.” Id. § 482.
    Specifically, the shareholders of an export corporation could
    create a commonly controlled FSC and then make “sale[s]
    of export property” to the FSC at hypothetical “transfer
    price[s]” that were fixed by a complex statutory formula
    “regardless of the sales price actually charged.” Id. § 925(a).
    As with the DISC system, the FSC statute required the
    Secretary to issue regulations that would establish
    comparable rules “in the case of commissions, rentals, and
    other income,” id. § 925(b)(1), and the Secretary did so, see,
    e.g., 
    26 C.F.R. § 1.925
    (a)-1T(d)(2). Similar to their DISC
    counterparts, these regulations set forth specific instructions
    for calculating the “maximum commission the FSC may
    charge” the export corporation and the “amount of the
    income that may be earned by the FSC in any year.” 
    Id.
    § 1.925(a)-1T(d)(2)(ii), (iv). Once again, the details of these
    formulas are not relevant here. What matters is that the
    formulas allowed the FSC’s commissions and income to be
    set at artificial levels that did not necessarily correspond to
    the actual value of any services provided by the FSC. See
    id. § 1.925(a)-1T(a)(3) (application of certain pricing rules
    5
    There appears to be some debate as to whether the phrase should
    be “a FSC” (which assumes that the term is pronounced “a Fisc”) or
    should instead be “an FSC” (which assumes that it is pronounced “an F-
    S-C”). We follow the statute, which consistently uses the phrase “a
    FSC.” See, e.g., I.R.C. § 921(a).
    MAZZEI V. CIR                              15
    “does not depend on the extent to which the FSC performs
    substantial economic functions beyond those required by
    section 925(c)”).
    In contrast to a DISC, whose income is generally exempt
    from tax, see I.R.C. § 991, a FSC’s income was partially
    subject to tax. Specifically, after an export company paid
    tax-deductible commissions to its related FSC, a statutorily
    specified portion of the FSC’s income attributable to those
    commissions was declared to be “exempt foreign trade
    income.” Id. § 923(a)(1); see also id. §§ 923(b), 924(a). The
    statute stated, in turn, that “[e]xempt foreign trade income”
    would be “treated as foreign source income which is not
    effectively connected with the conduct of a trade or business
    within the United States,” thereby exempting such income
    from taxation. Id. § 921(a). 6 The remaining non-exempt
    portion of the FSC’s foreign trade income, however, was still
    subject to the corporate income tax rate. The net effect of
    these provisions was to allow an export corporation to
    allocate a portion of its export sales income to the FSC by
    paying the FSC artificially determined “commissions,” with
    the consequence that the export corporation paid no income
    tax on any of the commissions (which it deducted as an
    expense) and the FSC paid income tax only on the non-
    exempt portion of its income attributable to those
    commissions.
    6
    To take advantage of these rules, a FSC generally had to be
    managed, and transact its business, outside the United States. I.R.C.
    § 924(b)(1), (c), (d). However, those requirements generally did not
    apply to a “small FSC,” id. § 924(b)(2)(A), as that term was defined by
    statute, id. § 922(b). It is undisputed that the relevant FSC in this case
    was a “small FSC,” and it therefore was not subject to these additional
    requirements.
    16                     MAZZEI V. CIR
    The taxation of a FSC’s dividend payments differs in
    some respects from those of a DISC. Dividends that are
    distributed by a FSC to a domestic parent corporation out of
    the earnings and profits attributable to the FSC’s foreign
    trade income are generally not subject to corporate income
    tax. I.R.C. § 245(c)(1)(A). This allowed the export
    corporation to effectively allocate income to the FSC, where
    it was subject to reduced taxation, and then to receive back
    some of those funds as dividends without paying income tax
    on them. The Commissioner estimates that the bottom-line
    result of these complex rules was to allow “a U.S.
    manufacturer to reduce its corporate income tax on export
    sales by approximately 15%.”
    If the FSC paid dividends to individual shareholders,
    then those dividends would generally be subject to taxation
    under the default rule that dividends are treated as income.
    See I.R.C. § 1(h)(11). By contrast, if an IRA was the
    shareholder of the FSC, then any FSC dividend received by
    the IRA, like almost any other income to the IRA, is exempt
    from taxation. See id. § 408(e)(1). Although the general rule
    against taxation of IRA income does not apply to “unrelated
    business income” that is taxed under § 511, see id.
    § 408(e)(1), the default rule under the Code is that dividends
    are excluded from “unrelated business taxable income,” id.
    § 512(a)(1), (b)(1). As noted earlier, see supra at 11–12, the
    Code contains a special provision that expressly reverses
    that default rule in the case of dividends paid by “a DISC”
    to a tax-exempt entity (such as an IRA), see id. § 995(g), and
    that means that an IRA must pay tax on such “unrelated
    business income” under § 511, see id. § 408(e)(1). But the
    Code contains no such similar provision with respect to
    dividends of a FSC that are paid to a tax-exempt shareholder,
    such as an IRA, and so the default rule remains in place. And
    if the IRA that owned the FSC shares was a Roth IRA, as
    MAZZEI V. CIR                             17
    opposed to a traditional IRA, then the authorized
    distributions from the IRA to the individual holder of the
    account would not be taxed either. The net result of having
    a Roth IRA hold the shares of a FSC would thus be that
    (1) the export corporation would pay no tax on the income it
    allocated as “commissions” to the FSC; (2) the FSC would
    pay only a reduced level of corporate income tax on the
    income attributable to its commissions; (3) the Roth IRA
    would pay no tax when it received dividends from the FSC;
    and (4) the individual IRA holder would pay no tax when
    receiving the FSC dividends in the form of authorized IRA
    distributions. That is, only one of these four transactions
    would be taxable and that one only at a reduced effective
    rate.
    B
    With this complex statutory background in place, we can
    now turn to the facts of this case. We first describe the
    Mazzeis’ relevant transactions and then recount the
    proceedings below.
    1
    In 1977, Angelo Mazzei filed a patent application for an
    “injector” that added fertilizers to the water used in
    agricultural irrigation systems.     The following year,
    recognizing the business potential in his invention, Angelo
    and his wife Mary Mazzei formed the Mazzei Injector Corp.
    (“Injector Corp.”) as an S corporation. 7 Angelo and Mary
    7
    “S corporations” are ordinary business corporations that elect to
    pass corporate income, losses, deductions, and credits through to their
    individual shareholders for federal tax purposes. See I.R.C. §§ 1361–
    1379. Thus, the S corporation generally pays no income tax, and the
    shareholders of S corporations instead report the flow-through of income
    18                         MAZZEI V. CIR
    thereafter actively ran the business, although Mary later
    reduced her role. Once their daughter, Celia, graduated from
    college, she became more active in the company and served
    as its vice president of research and development. During
    the time period at issue in this case, Angelo and Mary each
    owned 45 percent of Injector Corp. while Celia owned the
    remaining 10 percent. Through the Mazzeis’ efforts,
    Injector Corp. grew rapidly, and by 1984, the business began
    exporting its products through foreign distributors. By the
    late 1990s, export sales provided a steady stream of revenue
    to Injector Corp.
    The Mazzeis also owned a 20-acre farm, and as a result
    they were long-time members of the Western Growers
    Association (“WGA”), a trade association representing
    farmers. In the 1990s, WGA developed a program for its
    members that would facilitate their use of FSCs, and in 1998
    the Mazzeis decided to participate in that program. In
    connection with doing so, the Mazzeis took steps to set up
    Roth IRAs. The amount that may be contributed to a Roth
    IRA is determined according to a statutory formula, see
    I.R.C. § 408A(c), and for the years prior to 1998, each of the
    Mazzeis’ contribution limits to a Roth IRA was zero.
    Through a complex business restructuring that the
    Commissioner does not challenge here, each of the Mazzeis
    had a Roth IRA contribution limit of $2,000 for 1998 only.
    Under that restructuring, the Mazzeis formed another S
    corporation, ALM Corp., which was owned in the same
    proportions as Injector Corp. ALM Corp. and Injector
    and losses on their personal tax returns and pay tax at their individual
    income tax rates. Id. §§ 1363(a), 1366. In this way, S corporations avoid
    the problem of double taxation in which the corporation would first pay
    tax on its income and then the individual shareholder would pay tax on
    distributions received from the corporation.
    MAZZEI V. CIR                           19
    Corp., in turn, then formed Mazzei Injector Co. (“Injector
    Co.”), an LLC that was treated as a partnership for tax
    purposes. Having secured a Roth IRA contribution limit of
    $2,000 for 1998, each of the Mazzeis opened a Roth IRA and
    contributed $2,000. However, in the ensuing four calendar
    years (1999 through 2002), the Roth IRA contribution limits
    for each of the Mazzeis reverted back to zero.
    Meanwhile, the newly formed entity, Injector Co.,
    applied to join WGA’s FSC program. Once WGA approved
    Injector Co.’s application, the Mazzeis took steps to
    establish a FSC under WGA’s auspices. The WGA FSC
    program took advantage of the statute’s allowance of a
    “shared FSC,” under which an entity (such as WGA) could
    arrange for a FSC to maintain “separate account[s]” that
    each would then generally “be treated as a separate
    corporation for purposes” of the FSC statute. I.R.C.
    § 927(g)(1), (g)(3)(A). In formally establishing their FSC as
    a separate account in one of WGA’s shared FSCs, the
    Mazzeis arranged for their separate Roth IRAs to each
    purchase 33⅓ shares of their FSC, at a total price of $500 for
    the 100 shares. The Mazzeis also elected to have their FSC
    treated as a “small FSC,” which meant that it was not subject
    to the same foreign-presence requirements as regular FSCs.
    See supra note 6.
    WGA also provided Injector Co. with drafts of the
    various agreements that would be needed to ensure that its
    FSC—which was ultimately a separate account in the
    “Western Growers Shared Foreign Sales Corporation IV
    Ltd.” (“WG FSC IV”) 8—would be able to operate as
    8
    The relevant shared FSC was originally “Western Growers Shared
    Foreign Sales Corporation III Ltd.,” but because the change makes no
    difference here, we will refer only to “WG FSC IV.” And because
    20                        MAZZEI V. CIR
    intended, and Injector Co. executed these agreements in
    early 1998. These various agreements underscore what the
    statutory framework expressly contemplates, which is that
    the FSC would be paid commissions that were set according
    to regulatory formulas and that did not reflect any actual
    services provided by the FSC.
    First, Injector Co. and WG FSC IV executed a “Foreign
    Trade Commission, Sale, License, Lease and Services
    Agreement” (“Commission Agreement”), under which WG
    FSC IV agreed to perform certain activities and services for
    Injector Co. “but only to the extent it can delegate such
    activities and services” back to Injector Co. “and is not
    required to use its own assets and/or personnel to perform
    such activities and services” (emphasis added). Thus, for
    example, WG FSC IV agreed to “promote the license, lease
    and sale” of Injector Co.’s products, but it also stated that
    none of these activities “shall be of the type which involve
    the use of the FSC’s own assets or personnel to perform such
    activities.” The Commission Agreement also specified that
    if a particular sale, license, or lease was “considered as
    solicited or promoted” by WG FSC IV, then the FSC would
    receive a commission, but that Injector Co. would have the
    “final decision” as to whether the FSC was to be “considered
    as having solicited or promoted a transaction” (emphasis
    added). If a commission was to be paid, then it would be
    determined by mutual agreement in accordance with the
    formulas in the applicable federal FSC regulations “so as to
    provide the maximum federal income tax benefits” to
    Injector Co.       Likewise, the Commission Agreement
    specified that if Injector Co. “performs any service for a
    nothing turns on the distinction here, we will also for the sake of
    simplicity use “WG FSC IV” interchangeably to refer to both the shared
    FSC and the Mazzeis’ separate account within that shared FSC.
    MAZZEI V. CIR                       21
    customer that would constitute” a relevant service “if
    performed by [WG FSC IV] for a customer considered as
    solicited or promoted” by the FSC, then Injector Co. would
    pay a “commission” to the FSC. Once again, Injector Co.
    had the “final decision” as to whether WG FSC IV would be
    “considered” to have solicited or promoted a transaction, and
    any commission paid would be determined by mutual
    agreement in accordance with the relevant regulatory
    formulas.
    Second, consistent with what was expressly
    contemplated in the Commission Agreement, the “Export
    Related Services Agreement” (“Services Agreement”)
    formally delegated back to Injector Co. the relevant
    activities and services that WG FSC IV was to perform in
    connection with “earning foreign trade income.” WG FSC
    IV agreed to pay Injector Co. a “service fee” for performing
    these services, but any such fee could not exceed the
    commissions that the FSC received and was to be
    “immediately offset against the discretionary commissions
    which [Injector Co.] would otherwise pay to [the FSC].”
    The agreement further provided that services would be
    deemed to have been performed by Injector Co. for WG FSA
    IV only to the extent required to “maxim[ize] federal income
    tax benefits.”
    Third, under the “Management Contract,” WG FSC IV
    agreed to pay “administrative fees” to Quail Street
    Management (“Quail Street”), the Bermuda-based
    management company that administered WGA’s FSC
    program. The fee was set at 0.1 percent of the FSC’s foreign
    gross trading receipts as defined in Internal Revenue Code
    § 924. The fee had to be at least $3,500 and at most $10,000.
    Fourth, under the “Shareholders’ Agreement,” each IRA
    shareholder owned one-third of their FSC’s 100 shares,
    22                        MAZZEI V. CIR
    which could not be sold without the approval of the FSC’s
    directors. The agreement confirmed the $500 purchase price
    for the 100 shares and specified that this amount consisted
    of $1 of “paid-in capital” and $499 of “paid-in surplus.” The
    agreement further stated that, in the event that the FSC
    exercised its right to purchase the FSC stock from the
    shareholders, the purchase price would be the paid-in-capital
    amount ($1). However, the agreement specified that this
    right of purchase did not apply in the case of an “IRA
    Shareholder” and that any such sale by an IRA Shareholder
    to the FSC was prohibited.
    With these agreements in place, Injector Co. thereafter
    reported its foreign sales to Quail Street each quarter. Based
    on these numbers, Quail Street computed the maximum
    commission that Injector Co. was allowed to pay to the FSC
    in accordance with the federal FSC regulatory formulas.
    Quail Street then reported that amount in letters to the
    Mazzeis that identified (1) the amount of the FSC tax that
    had been paid (and that had to be reimbursed); 9 and (2) the
    remainder amount that could be distributed to the IRA
    shareholders. In accordance with these instructions, Injector
    Co. paid a total of $558,555 in commissions and taxes to WG
    FSC IV between 1998 and March 2002. In turn, the FSC
    paid $533,057 in dividends to the Mazzeis’ Roth IRAs over
    that same time period.
    9
    As explained earlier, only a portion of the commissions received
    by a FSC are untaxed, see supra at 15, and so the FSC here paid tax on
    a portion of Injector Co.’s payments and distributed the rest to the
    Mazzeis’ Roth IRAs. The Roth IRAs did not pay tax on these FSC
    dividends, but had the dividends instead been paid to the Mazzeis
    individually, they would have owed tax on the dividends. See supra
    at 16.
    MAZZEI V. CIR                              23
    Through these various steps, the Mazzeis took full
    advantage of the tax benefits described earlier. See supra
    at 17. The corporations that generated the foreign sales
    ultimately benefitted from a tax deduction for the
    “commissions” paid to the FSC. WG FSC IV paid a modest
    amount of tax on the income attributable to its commissions.
    The Roth IRAs paid no tax on the substantial dividends they
    received from the FSC because (unlike § 995(g) in the case
    of a DISC) there is no statutory provision imposing such a
    tax in the case of a FSC. And, now that the funds are safely
    in the Roth IRAs, they can be withdrawn by the Mazzeis tax
    free when they are eligible to make such withdrawals.
    2
    Unsurprisingly, the Commissioner did not like this
    arrangement. On April 6, 2009, the Commissioner served
    notices of deficiency against each of the Mazzeis. The
    Commissioner asserted that the $533,057 that had been paid
    by WG FSC IV into their respective Roth IRAs should be
    deemed, in substance, to be contributions to their Roth IRAs
    that exceeded their statutory contribution limits. For tax
    years 2002 through 2007, the Commissioner asserted excise
    tax deficiencies against Angelo and Mary (who filed joint
    returns) in the amount of $67,590, as well as penalties
    totaling $19,215. 10 For tax years 2002 through 2007, the
    Commissioner asserted against Celia excise tax deficiencies
    of $40,692 and penalties totaling $11,912. All three
    petitioned the Tax Court for a redetermination of the
    deficiency in tax, and the cases were consolidated.
    10
    The penalties were imposed for failing to timely file a tax return,
    see I.R.C. § 6651(a)(1), and for failing to timely pay the tax shown on a
    return, see id. § 6651(a)(2).
    24                        MAZZEI V. CIR
    The consolidated case was tried on November 20, 2014
    before Judge Mark Holmes. After Judge Holmes circulated
    his proposed opinion within the Tax Court, the full Tax
    Court determined to decide the matter. See I.R.C. § 7460(b);
    see also Mazzei v. Commissioner, 
    150 T.C. 138
    , 184 n.1
    (2018) (Holmes, J., dissenting). The Tax Court ultimately
    upheld the Commissioner’s assessment of excise taxes
    against the Mazzeis by a vote of 12 to 4 (with Judge Holmes
    dissenting), but the Tax Court unanimously set aside all of
    the penalties. Mazzei, 150 T.C. at 168, 182. Invoking the
    doctrine of substance over form, the Tax Court concluded
    that the Roth IRAs’ purchase of the FSC stock did not reflect
    “the underlying reality” because the “Roth IRAs effectively
    paid nothing for the FSC stock, put nothing at risk, and from
    an objective perspective, could not have expected any
    benefits” from that ownership. See id. at 167–68. The court
    therefore “disregard[ed] the purchase” and treated the
    Mazzeis as “the owners of the FSC stock for Federal tax
    purposes at all relevant times.” Id. at 168. That meant that
    the payments from the FSC must be “recharacterized as
    dividends from the FSC” to the Mazzeis. 11 Id. And that
    meant that the payments into the Roth IRAs were made by
    the Mazzeis and were, therefore, excess contributions to the
    Roth IRAs by the Mazzeis. Id.
    The dissenters disagreed, asserting that the majority had
    overlooked the import of the special rules that governed
    FSCs, which expressly allowed transactions between
    commonly held entities that lacked economic substance. In
    11
    The logic of the Tax Court’s reasoning would suggest that the
    Mazzeis should have paid income taxes on those dividends. See supra
    at 16. But as the Tax Court noted, “any income tax issues from 1998–
    2001 are barred” by the “statute of limitations” in I.R.C. § 6501. See
    150 T.C. at 149 n.15.
    MAZZEI V. CIR                        25
    particular, the dissenters questioned the majority’s
    conclusion that, because the Roth IRAs had “paid so little”
    for their FSC stock and had put nothing at risk, they could
    not be the true owners of the FSC. 150 T.C. at 192–93
    (Holmes, J., dissenting). As the dissent explained, “the
    Mazzeis also put nothing at risk to get the FSC, so by the
    majority’s reasoning they couldn’t have owned the FSC
    either.” Id. at 193. Indeed, the dissenters argued that, under
    a consistent application of the majority’s reasoning, “no one
    could ever own an FSC because FSCs never put capital at
    risk.” Id.
    The Mazzeis filed a motion for reconsideration and a
    motion to vacate, which the Tax Court denied. The Mazzeis
    timely appealed to this court.
    II
    In addressing the parties’ contentions on appeal, we
    begin by identifying several points that are not in dispute. In
    particular, the Commissioner does not contend that the
    Mazzeis failed to follow any of the formalities required by
    the Internal Revenue Code concerning the FSC or their Roth
    IRAs. On the contrary, the Commissioner stipulated at trial
    that WG FSC IV met all of the requirements for a small FSC;
    that the Mazzeis’ Roth IRAs were properly established under
    the Code; that there had not been a prohibited transaction
    involving the Roth IRAs within the meaning of I.R.C.
    § 4975; and that compliance with I.R.C. § 482—which (as
    noted earlier, see supra at 14) addresses allocation of income
    and deductions among commonly controlled entities—was
    “not at issue in this case.” Nor has the Commissioner
    contended that any commissions that Injector Co. paid to the
    FSC were calculated incorrectly under the applicable
    statutory and regulatory formulas. See Mazzei, 150 T.C.
    at 175.
    26                     MAZZEI V. CIR
    Rather than contest whether the Mazzeis followed the
    letter of the Code, the Commissioner instead asked the Tax
    Court to “‘recharacterize [the Mazzeis’] entire scheme’”
    under the “doctrine of substance over form.” See 150 T.C.
    at 150. The Tax Court, however, expressly rejected the
    Commissioner’s “request for a complete recharacterization
    of all [of the Mazzeis’] transactions,” id. at 151, and the
    Commissioner has not challenged that ruling in this court.
    Instead, the Tax Court recharacterized only one of the
    transactions at issue, viz., the purchase of the FSC’s stock by
    the Roth IRAs. Id. Accordingly, the only issue before us is
    whether the Tax Court properly concluded that, under the
    substance-over-form doctrine, the Mazzeis, rather than their
    Roth IRAs, were the owners of the FSC for federal tax
    purposes.
    We review the Tax Court’s decision “in the same manner
    and to the same extent as decisions of the district courts in
    civil actions tried without a jury.” I.R.C. § 7482(a)(1). “We
    review questions of fact for clear error.” Knudsen v.

    interpretations of the Internal Revenue Code, de novo.”

    and taxation statutes, ‘form should be disregarded for
    substance and the emphasis should be on economic reality.’”
    (citation omitted)). Indeed, quoting Professor Boris Bittker,
    we have described this “substance-over-form doctrine” and
    other related doctrines as resembling, in combination, a sort
    of “‘preamble to the Code, describing the framework within
    which all statutory provisions are to function.’” Stewart v.
    Commissioner, 
    714 F.2d 977
    , 987–88 (9th Cir. 1983)
    (quoting Boris I. Bittker, Pervasive Judicial Doctrines in the
    Construction of the Internal Revenue Code, 
    21 How. L.J. 693
    , 695 (1978)).         Under these settled background
    principles, this would be an easy case if it involved ordinary
    business entities, as opposed to the distinctive vehicle of a
    FSC. The taxpayers used what is essentially a shell
    corporation to engage in arbitrarily priced, self-dealing
    transactions that lacked economic substance and then
    funneled those proceeds as “dividends” to a tax-free Roth
    IRA. This would appear to present a paradigmatic case to
    apply such doctrines. Cf., e.g., Repetto v. Commissioner,
    
    103 T.C.M. (CCH) 1895
    , 
    2012 WL 2160440
    , at *9–12
    (2012) (invoking substance-over-form doctrine where two
    Roth IRAs respectively received dividends from commonly
    controlled C corporations that received “service” payments
    without themselves actually performing any business
    services).
    But like any background maxim that informs the
    construction and application of a statute, the doctrine of
    substance over form can be negated by Congress in express
    statutory language. See Chickasaw Nation v. United States,
    
    534 U.S. 84
    , 94 (2001) (interpretive “canons are not
    mandatory rules” and “other circumstances evidencing
    congressional intent can overcome their force”). Thus, there
    are some circumstances “‘when form—and form alone—
    determines the tax consequences of a transaction,’” Stewart,
    28                     MAZZEI V. CIR
    
    714 F.2d at 988
     (citation omitted), such as when “statutory
    provisions deliberately elevate, or have been construed to
    elevate, form above substance,” see 1 Boris I. Bittker &
    Lawrence Lokken, Federal Taxation of Income, Estate and
    Gifts ¶ 4.3.3, at 4-34 (3d ed. 1999). This is such a case. As
    we have set forth in detail above, Congress has expressly
    decreed that FSCs can engage in transactions, with
    commonly controlled entities, that lack any economic
    substance and that are assigned hypothetical values
    determined according to statutory formulas that bear no
    relationship to any underlying real-world valuation. See
    supra at 13–15. Indeed, as this case well illustrates, the
    entire FSC need not have any substance to it because it can
    “contract” for another related entity to perform its relevant
    activities.    See I.R.C. § 925(c); see also 
    26 C.F.R. § 1.925
    (a)-1T(a)(3) (application of the relevant valuation
    formulas “does not depend on the extent to which the FSC
    performs substantial economic functions beyond those
    required by section 925(c)”); Mazzei, 150 T.C. at 157 (noting
    that, under the FSC regime, a “related supplier was permitted
    to pay the FSC a ‘commission’ for services (relating to an
    export transaction) that were not, in substance, performed by
    the FSC (although the FSC could perform such services if it
    wished)”).      Put simply, the FSC statute expressly
    contemplates that, without itself performing any services, a
    FSC can receive “commissions” from a related entity and
    then (after paying a reduced level of tax) the FSC can pay
    the remainder as dividends to the same or another related
    entity. Under the scheme that Congress devised in the FSC
    statute, the taxation rules in certain respects plainly follow
    the form of the matter and not its substance.
    The question in this case, then, is whether the Tax Court
    applied the substance-over-form doctrine in a manner that
    properly takes account of Congress’s limited abrogation of
    MAZZEI V. CIR                       29
    that doctrine here. The Tax Court construed that abrogation
    very narrowly, saying that Congress endorsed form over
    substance only with respect to the “specific transactions” in
    which the export company pays commissions based on
    statutory formulas that lack any economic reality, and then
    “only for the purpose of computing the income taxes of the
    FSC and its related supplier.” See Mazzei, 150 T.C. at 159
    (emphasis added). Beyond that, the Tax Court concluded,
    the FSC statute left the substance-over-form doctrine intact.
    As that court stated, “[n]o part of the FSC statutes and
    regulations states, or even implies, that purchases or
    transfers of FSC stock, or any transactions at the shareholder
    level or between the FSC and its owners, are exempt from
    application of the substance doctrines, which are our normal
    tools of statutory interpretation.” Id. at 160 (simplified).
    The Tax Court therefore held that the FSC statute’s partial
    abrogation of substance-over-form principles did not apply
    “in deciding who actually owned the FSC stock” and that
    that question was therefore governed by “normal substance
    principles.” Id. at 154. While we share the Tax Court’s
    concern that exemptions from normal substance-over-form
    rules should not be read overly broadly, we cannot agree
    with that court’s extremely restrictive view of the exemption
    reflected in the FSC statute. In our view, the Tax Court’s
    invocation of the substance-over-form doctrine in this case
    rests on subsidiary premises that cannot be reconciled with
    what Congress has decreed with respect to FSCs.
    B
    1
    In applying normal substance-over-form principles to
    the issue of the ownership of WG FSC IV, the Tax Court
    considered whether the stockholders—i.e., the Roth IRAs—
    had “the benefits and risks of ownership,” or whether some
    30                         MAZZEI V. CIR
    other entity possessed them. 150 T.C. at 163. The court
    noted that the Roth IRAs had put essentially nothing at risk
    because the $500 “prearranged” price they paid for the FSC
    stock bore no “relationship to the actual value” of that stock.
    Id. at 165. The court concluded that the $500 the Roth IRAs
    paid thus “represented at most a de minimis risk which was
    insufficient to give substance to the Roth IRAs’ purported
    ownership of the FSC stock.” 12 Id. at 164. The Tax Court
    also addressed “what benefits an independent holder of the
    FSC stock could realistically have expected on the basis of
    the ‘objective nature’ of the FSC stock,” and the court
    concluded that there were none: because “Injector Co.
    retained complete control over whether any of its export
    receipts would flow to the FSC in any year,” it followed that
    “no independent holder of the FSC stock could realistically
    have expected to receive any benefits (before or after tax)
    due to its formal ownership of the FSC stock.” Id. at 166–
    67. Because the Roth IRAs thus lacked the risks and benefits
    of ownership, the court “disregard[ed]” their purchase of the
    FSC stock. Id. at 168. Instead, the court concluded, the
    Mazzeis (through Injector Co.) were the true owners of the
    FSC. Id. And that meant that, under Commissioner v.
    12
    Indeed, the Tax Court suggested that, despite the parties’
    agreement that the total stock was worth “$100 when it was purchased,”
    the actual value was only $1 because that was the sale price set forth in
    the Shareholders’ Agreement in the event that the shareholders sold their
    stock. Mazzei, 150 T.C. at 165. The rest of the purchase price, according
    to the Tax Court, was simply a fee to WGA. Id. This analysis appears
    to overlook the fact that the $1 mandatory sale price, by its terms, only
    applied to a purchase of the stock by WG FSC IV and that this option to
    purchase did not apply if (as here) the stock was owned by an IRA.
    Although a sale of the stock by the Roth IRAs to some other party would
    still have required the approval of WG FSC IV’s directors, the agreement
    does not appear to specify a price in such circumstances. In all events,
    our analysis does not depend upon whether the value of the FSC stock at
    the time of purchase was $1, $100, or $500.
    MAZZEI V. CIR                        31
    Banks, 
    543 U.S. 426
     (2005), the income of the FSC that was
    paid out as dividends was, in the view of the Tax Court,
    received by the Mazzeis for tax purposes. Mazzei, 150 T.C.
    at 160–61 (“‘In an ordinary case attribution of income is
    resolved by asking whether a taxpayer exercises complete
    dominion over the income in question.’” (quoting Banks,
    
    543 U.S. at 434
    )).
    The problem with this analysis is that its underlying
    premises are directly contrary to what is expressly
    contemplated by the FSC statute. It makes no sense to ask
    whether the formal owner of the FSC stock would, by virtue
    of that purchase, be exposed to any risk as a result of that
    ownership because the statute allows FSCs to be set up so as
    to eliminate any risk from owning the FSC stock.
    Specifically, the statute explicitly authorizes the
    establishment of a FSC that will not conduct any operations
    itself, and in such cases the FSC will effectively be a shell
    corporation that generates value only by virtue of the
    reduced rate of taxation that is paid on moneys that are
    funneled through it in accordance with strict statutory
    formulas. See supra at 13–17, 27–28. Such a shell
    corporation presents little, if any, risk at all to its owner
    because it will be used only if and when there is value (in the
    form of tax savings) to be obtained by flowing funds through
    it.
    The Tax Court discounted this point, noting that
    “nothing in the Code prevents an FSC shareholder from
    capitalizing its FSC,” and such capital could be at risk.
    Mazzei, 150 T.C. at 164 n.36 (emphasis added). This is an
    ironic comment to make in an analysis that is supposedly
    focused on economic realities. The reality is that, for a FSC
    to function as the statute contemplates, there must be related
    parties on both sides of the FSC, because the whole point of
    32                        MAZZEI V. CIR
    the FSC vehicle is to cycle money through it so that it is
    taxed at the FSC’s lower rate. The statute clearly envisions
    that the parties who pay money into the FSC and the parties
    who receive dividends out of it will be related. 13 Given that
    reality, it would not make much economic sense to
    “capitalize” the FSC with more than a nominal amount of
    capital. As the dissenters noted, taking the Tax Court’s
    analysis seriously would lead to the illogical conclusion that
    “no one could ever own an FSC” because no owner would
    ever “put capital at risk” in the FSC. Id. at 193 (Holmes, J.,
    dissenting). The Tax Court also claimed that the Mazzeis
    (unlike the Roth IRAs) did have risk because they were
    “exposed at all times” to the risk “that their investment in
    their export business would decline.” Id. at 165 n.37
    (majority opinion). But this is the risk that the Mazzeis faced
    as the owners of Injector Co.; it is not a risk that they would
    face as the owners of the FSC.
    Moreover, it makes even less sense to ask, as the Tax
    Court did, “what benefits an independent holder of the FSC
    stock could realistically have expected.” 150 T.C. at 166
    (emphasis added). By statutory design, a FSC typically will
    not be owned by an “independent” entity; it will be owned
    by “a person described in section 482,” I.R.C. § 925(a)—
    viz., an entity “owned or controlled directly or indirectly by
    the same interests,” id. § 482 (emphasis added). As we have
    explained, the tax benefits associated with the FSC regime
    contemplate related entities on both sides of the FSC. See
    supra at 14, 31–32. As a result, no “independent” person
    would realistically be expected to obtain value from owning
    13
    One possible exception might be a scenario in which the FSC is
    effectively used to make a gift to a third party. Cf. Benenson, 910 F.3d
    at 696 n.5. We express no view on how the Code and regulations would
    apply in such a distinct scenario.
    MAZZEI V. CIR                              33
    an FSC because a foreign exporter would have no practical
    incentive to choose to pour money into such a FSC. 14
    For similar reasons, the Tax Court’s reliance on the
    “anticipatory assignment doctrine” discussed in Banks,
    
    543 U.S. at 434
    , is also flawed. That doctrine states that, as
    a general matter, “gains should be taxed ‘to those who
    earned them,’” so that a “taxpayer cannot exclude an
    economic gain from gross income by assigning the gain in
    advance to another party.” 
    Id. at 433
     (citation omitted). The
    FSC regime explicitly departs from that principle as well
    because the key feature of the FSC mechanism is that the
    relevant income earned by the export company is instead
    funneled to the FSC—which did not earn it—and it is then
    taxed at the FSC level (rather than the export company level)
    before then being cycled back out to a related entity. 15
    Application of the anticipatory assignment doctrine here
    would mean that Injector Co., rather than the FSC, should be
    treated as the earner of the income, all of which was
    produced by Injector Co.’s efforts. Such an outcome, of
    course, is directly contrary to the scheme of the FSC statute.
    The Tax Court sought to side-step this problem by
    14
    Moreover, in treating the Roth IRA ownership as illusory, the Tax
    Court overlooked that there are real-world consequences to the fact that
    the Roth IRAs own the FSC rather than Injector Co. or the Mazzeis.
    Although there are certainly tax advantages to that arrangement, one
    consequence of that ownership is that the moneys distributed by the FSC
    to the Roth IRAs as dividends could not be withdrawn without penalty
    unless and until the respective owner is eligible to make qualified
    withdrawals. For a younger individual such a Celia Mazzei, that is not
    an insignificant limitation.
    15
    As noted earlier, if the related entity that received the money on
    the return trip is taxed as a corporation, then it typically pays no tax on
    those dividends when they are received from the FSC. See I.R.C.
    § 245(c)(1)(A); supra at 16.
    34                     MAZZEI V. CIR
    characterizing the FSC as the generator of the income, see
    Mazzei, 150 T.C. at 161, but of course the FSC did pay tax
    on its income. The court purported to treat the dividends as
    the relevant income, see id., but that approach—which asks
    who controls the assignment of the FSC’s dividends—
    simply begs the earlier-addressed question of who owns the
    FSC.
    Accordingly, the Tax Court’s application of substance-
    over-form principles in determining who owned the FSC in
    this case rested critically on subsidiary premises that directly
    conflict with the very features of the FSC regime that
    explicitly depart from such principles. The court therefore
    erred in invoking such principles to set aside the Roth IRAs’
    formal ownership of the FSC’s shares.
    2
    This conclusion is reinforced by two further textual clues
    in the language of the FSC statute.
    First, as noted earlier, the special hypothetical valuation
    formulas contained in the FSC statute are an express
    exception to the allocation rules that would otherwise govern
    under § 482 of the Code, and the statute thus expressly
    contemplates that a FSC will ordinarily receive its funds
    from “a person described in section 482,” I.R.C. § 925(a)—
    viz., an entity “owned or controlled directly or indirectly by
    the same interests,” id. § 482 (emphasis added). Because the
    FSC statute waives the normal rules with respect to any
    “person described in section 482,” the statute applies its
    special rules regardless of which related entity owns it. Id.
    § 925(a). The Tax Court’s reasoning, however, effectively
    rewrites this provision as if it required the export company
    that funnels money into the FSC to be the one that owns it
    and that therefore would receive the dividends out of it. But
    MAZZEI V. CIR                        35
    nothing in the statute imposes such a requirement, and the
    text of § 925(a) negates it.
    Second, Congress is obviously aware that tax-free
    entities, including IRAs, can own a FSC because the FSC
    was modeled on the DISC and Congress added a provision
    to specifically address that scenario only in the DISC
    context. The DISC and FSC statutes use identical language
    in waiving the normal allocation rules that would apply to
    the DISC or FSC in a transaction with “a person described
    in section 482,” and both statutes therefore contemplate that
    a variety of related entities might be the holder of the DISC
    or FSC stock, including tax-exempt entities like IRAs.
    Compare I.R.C. § 925(a) with id. § 994(a). But as noted
    earlier, Congress in 1988 enacted a special provision stating
    that, if a tax-exempt entity (such as an IRA) owns shares in
    a DISC, then any dividends distributed, or deemed
    distributed, to the IRA are generally “treated as derived from
    the conduct of an unrelated trade or business,” see id.
    § 995(g), and therefore subject to taxation under § 511. See
    supra at 11. Congress, however, did not add a similar feature
    to the then-existing FSC statute that would similarly tax
    dividends received by a tax-exempt entity that owns shares
    of a FSC. Congress could have taken similar steps either to
    impose a tax on dividends received by tax-exempt entities
    from a FSC or to prohibit FSC ownership by such entities
    altogether, but Congress must be deemed to have chosen not
    to do so. See Russello v. United States, 
    464 U.S. 16
    , 23
    (1983) (“Where Congress includes particular language in
    one section of a statute but omits it in another section of the
    same Act, it is generally presumed that Congress acts
    intentionally and purposely in the disparate inclusion or
    exclusion.” (simplified)). That may have been unwise, but
    we cannot rewrite the Code to impose an effective ban on
    36                     MAZZEI V. CIR
    FSC ownership by Roth IRAs, which is essentially what the
    Commissioner has asked us to do here.
    3
    Finally, our conclusion is supported by the decisions of
    the First, Second, and Sixth Circuits in three appeals arising
    from a single Tax Court proceeding involving a Roth IRA
    that indirectly owned shares in a DISC.
    In Summa Holdings, Inc. v. Commissioner, 
    109 T.C.M. (CCH) 1612
    , 
    2015 WL 3943219
     (2015), James Benenson,
    Jr. (“James Jr.”) and Sharen Benenson were the trustees of a
    trust (the “Benenson Trust”) for which their two sons
    (“James III” and Clement) were the beneficiaries. 
    2015 WL 3943219
    , at *1. The Benenson Trust, together with James
    Jr., owned most of the shares of Summa Holdings, a
    company whose subsidiaries had significant export sales. 
    Id.
    at *1–2. James III and Clement established Roth IRAs,
    which ultimately became equal shareholders in JC Holding,
    a C corporation, which in turn owned JC Export, a DISC. 
    Id.
    Through a series of agreements with Summa subsidiaries, JC
    Export received commissions from those subsidiaries in
    accordance with the statutory formulas applicable to DISCs.
    Id. at *2. JC Export then paid out the sums it received as
    dividends to JC Holding, and that company, as a C
    corporation, paid corporate tax on those sums. Id. After
    withholding that estimated tax, JC Holding then distributed
    the remainder equally as a dividend to James III’s and
    Clement’s Roth IRAs. Id. The Commissioner issued
    deficiency notices to several of the taxpayers involved, and
    the Tax Court ultimately relied on substance-over-form
    principles in concluding that the payments made by the
    Summa subsidiaries to JC Export “were not DISC
    commissions but deemed dividends to Summa’s
    shareholders followed by contributions to the Benenson
    MAZZEI V. CIR                         37
    Roth IRAs.” Id. at *8. As a result, Summa’s deduction of
    those commissions was disallowed; James Jr. and the
    Benenson Trust were found to have failed to report these
    “deemed” dividends as income; and James III and Clement
    owed excise taxes on the excess contributions to their Roth
    IRAs. Id. at *4, *9. These taxpayers each appealed to their
    respective circuit courts—Summa to the Sixth Circuit;
    James Jr. and Sharen (the trustees of the Benenson Trust) to
    the Second Circuit; and James III and Clement to the First
    Circuit. All three circuits ruled against the Commissioner.
    None of these decisions addressed the exact question
    presented here, but the First Circuit’s decision comes closest.
    That court addressed the Commissioner’s claim that the
    dividends received by the Benenson sons’ Roth IRAs should
    be characterized as contributions in excess of the applicable
    limits. Benenson v. Commissioner, 
    887 F.3d 511
    , 516–22
    (1st Cir. 2018). The First Circuit distinguished the Tax
    Court’s decision in the Mazzeis’ case on the grounds that, in
    the Benenson case, the Commissioner had “never challenged
    the valuation of the shares the Roth IRAs purchased.” Id.
    at 522; see also id. at 522 n.10. But in rejecting the
    Commissioner’s recharacterization of the transaction, the
    First Circuit nonetheless went on to make several points that
    are directly relevant to our analysis. Specifically, the First
    Circuit held that, in light of the Code provisions governing
    taxation of DISC dividends paid to C corporations and to
    tax-exempt entities, Congress had clearly permitted such
    entities to own DISCs and to receive DISC dividends. Id. at
    520–21. This recognition that Congress is aware that Roth
    IRAs and C corporations can own DISCs likewise applies in
    the FSC context. See supra at 35–36.
    Moreover, the First Circuit held that it did not matter that
    the dividends ultimately received by the Roth IRAs greatly
    38                     MAZZEI V. CIR
    exceeded any risk to the direct and indirect shareholders of
    the DISC. As the court explained, the Code provisions
    governing IRAs plainly allow the funds in an IRA “to grow
    through investment in qualified privately held companies,
    even during periods where the taxpayers are no longer
    allowed to contribute, and even if such growth occurs at a
    swift rate.” Benenson, 887 F.3d at 520 (emphasis added).
    And in response to the Commissioner’s complaint that this
    enormous return was for an investment in the DISC that
    involved “no risk” to the Roth IRAs, the First Circuit noted
    that this was “due to the unique, congressionally designed
    DISC corporate form.” Id. at 522. The same reasoning
    supports our earlier conclusion that, because a similar lack
    of risk is inherent in the “unique, congressionally designed
    [FSC] corporate form,” the Commissioner may not invoke
    that congressionally sanctioned feature as a basis for
    attacking the ownership structure of the FSC. See supra
    at 29.
    Although less directly relevant, the decisions of the Sixth
    and Second Circuits in the Benensons’ case are also
    consistent with our holding. The appeals in these two
    circuits involved different taxpayers (Summa in the Sixth
    Circuit and James Jr. and Sharen in the Second Circuit), but
    the underlying issue in both cases was the same—viz.,
    whether the commissions paid by the Summa subsidiaries to
    the DISC were properly recharacterized, under the
    substance-over-form doctrine, as dividends to Summa’s
    shareholders. Both courts answered that question in the
    negative. Underscoring the core point we have made here,
    the Second Circuit held that the Commissioner’s effort to
    invoke the substance-over-form doctrine to recharacterize
    the commissions to the DISC ignored the fact that “Congress
    has itself elevated form over substance insofar as DISC
    commissions are concerned by affording exporters
    MAZZEI V. CIR                       39
    ‘commission’ deductions for payments that lack the
    economic      substance     generally    associated    with
    commissions.” Benenson, 910 F.3d at 700. And the Sixth
    Circuit likewise noted that the Commissioner’s reliance on
    the doctrine could not be reconciled with the fact that the
    “Code authorizes companies to create DISCs as shell
    corporations that can receive commissions and pay
    dividends that have no economic substance at all.” Summa
    Holdings, 848 F.3d at 786; see also id. (“By congressional
    design, DISCs are all form and no substance . . . .”).
    We join our sister circuits in concluding that, when
    Congress expressly departs from substance-over-form
    principles, the Commissioner may not invoke those
    principles in a way that would directly reverse that
    congressional judgment.

    As the First Circuit noted in the Benenson case, some
    might think that what the Mazzeis did here was too “clever,”
    if not “unseemly.” 887 F.3d at 523. But as that court noted,
    the substance-over-form doctrine “is not a smell test,” it is
    “a tool of statutory interpretation.” Id. It may have been
    unwise for Congress to allow taxpayers to pay reduced taxes,
    and pay out dividends, “through a structure that might
    otherwise run afoul of the Code.” Id. at 518. But it is not
    our role to save the Commissioner from the inescapable
    logical consequence of what Congress has plainly
    authorized. Accordingly, to the extent that it was adverse to
    the Mazzeis, the judgment of the Tax Court is reversed.
    REVERSED.
