    versus
    United States of America, the Internal Revenue

    Appeal from the United States District Court
    for the Western District of Texas
    USDC No. 1:19-CV-607
    Before Smith, Duncan, and Oldham, Circuit Judges.
    Stuart Kyle Duncan, Circuit Judge:
    In 2005, John Rebold formed the Enelre Foundation as a Stiftung
    under the laws of Liechtenstein. Stiftung is a German word meaning, roughly,
    “foundation” or “endowment.” Enelre’s purpose is to provide education
    and general support for Rebold and his children. Rebold transferred $3
    million to Enelre’s bank accounts. He later learned the IRS would consider
    Enelre a “foreign trust,” triggering certain reporting requirements. Rebold
    belatedly filed the reports, and the IRS assessed penalties. Rebold paid the
    No. 21-51064
    penalties and then filed this refund action. The district court granted
    summary judgment for the government. We affirm.
    I.
    A.
    The Internal Revenue Code (IRC) requires disclosures regarding
    foreign trusts. See I.R.C. § 6048. Under section 6048(a), a “United States
    person” must report “the creation of any foreign trust” and “the transfer of
    any money or property (directly or indirectly) to a foreign trust.” Id.
    § 6048(a)(1), (3)(A)(i)–(ii). A “United States person” includes U.S. citizens
    and residents. Id. § 7701(a)(30)(A). These reportable events are disclosed to
    the IRS on Form 3520. 1 Failure to timely file the form or to fully disclose all
    required information results in a “penalty equal to the greater of $10,000 or
    35 percent of the gross reportable amount.” Id. § 6677(a). The “gross
    reportable amount” is “the gross value of the property involved in the event
    (determined as of the date of the event).” Id. § 6677(c).
    Under section 6048(b), as in effect during the years relevant to this
    case, anyone treated as the owner of a foreign trust under the grantor trust
    rules of I.R.C. §§ 671–679 must “ensure” the trust annually “makes a
    return . . . which sets forth a full and complete accounting of all trust
    activities and operations for the year, the name of the United States agent for
    such trust, and such other information as the Secretary may prescribe.” Id.

    § 6048(b)(1)(A) (2009). 2 The return is made on Form 3520-A. 3 Failure to
    timely file the form or to fully disclose all required information results in “a
    penalty equal to the greater of $10,000 or [5] percent of the gross reportable
    amount.” Id. § 6677(a)–(b). The “gross reportable amount” is “the gross
    value of the portion of the trust’s assets at the close of the year treated as
    owned by the United States person.” Id. § 6677(c)(2).
    B.
    Rebold was a U.S. citizen who worked overseas as an engineer in the
    oil and gas industry. In 2005, he traveled to Switzerland and created the
    Enelre Foundation as a Stiftung 4 under the laws of Liechtenstein. At the time
    2
    In 2010, Congress amended section 6048(b) to require that a foreign trust owner
    not only “ensure” the trust makes an annual return but also directly “submit” a return
    “with respect to such trust for such year.” I.R.C. § 6048(b)(1) (2010).

    Stiftung is translated from German to English as “foundation,” “establishment,”
    “donation,” or “endowment.” German-English Translation for “Stiftung,”

    603 F.3d 295
    , 299 n.1 (5th Cir. 2010).
    “A stiftung is a creation of the laws of Liechtenstein . . . , resembling a trust, but
    not limited to specific lives in being. A stiftung can own property and is controlled by an
    administrator (known as a stiftungerat) whose powers and duties are comparable to a
    trustee.” Kraus v. Comm’r, 
    59 T.C. 681
    , 685 (1973). “A Stiftung does not have members
    or a board of directors.” I.R.S. Chief Couns. Att’y Mem. AM2009-012, 
    2009 WL 3336014
    (Oct. 7, 2009). In forming a Stiftung, the founder “transfers specific assets to the Stiftung
    that are then endowed for specific purposes,” “states the objectives of the Stiftung[,] and
    appoints its [stiftungerat].” 
    Ibid.
     A Stiftung “can be created for charitable or personal
    purposes” but “cannot be created to undertake commercial activities.” Von E. Sanborn et

    No. 21-51064
    of Enelre’s founding, Rebold was the settlor and primary beneficiary, and his
    children were secondary beneficiaries. “Enelre” is the name of Rebold’s
    wife, Erlene, spelled backwards.
    Enelre’s organizing documents provide that its purpose is to provide
    education, training, support, and maintenance for its beneficiaries. The
    documents prohibit “commercial trade” and do not provide for allocation of
    profits. They refer to Enelre as a trust, and Enelre has trustees and pays
    trustee fees. Liechtensteinian Public Registry filings reiterate Enelre’s
    purpose and prohibition of commercial business.
    Rebold opened bank accounts for Enelre at Credit Suisse, UBS, and
    Bank Wegelin. He transferred $2 million to Enelre in 2005 and another $1
    million in 2007. Neither Rebold nor Enelre filed Form 3520 or 3520-A
    disclosing to the IRS the creation of Enelre or these transfers.
    In 2010, UBS notified Rebold that it intended to turn over Enelre’s
    account records to the IRS. Rebold consulted counsel regarding tax liability
    for Enelre. An attorney for “the trust and trustees” (i.e., Enelre and its
    trustees) advised Rebold’s counsel that Rebold was “an American who set
    up a foreign trust, so [h]e will need to do 3520’s and 3520-A’s as well as
    amended US returns,” and recommended that he participate in a voluntary
    disclosure program “to limit his exposure to penalties.” That attorney noted
    that Rebold “will owe some serious tax! Nothing to be taken lightly.”
    Rebold’s counsel explained that he was “trying to find a way to treat the
    A.B.A. Course of Study, SL003 ALI-ABA 293, 300 (July 2005). “Liechtenstein law
    provides that in certain cases commercial activities may be undertaken by a Stiftung if such
    activities serve its noncommercial purposes.” AM2009-012, 
    2009 WL 3336014
    . Once
    formed, the Stiftung “is entered onto the Register in Liechtenstein and must have a
    minimum amount of initial capital.” 
    Ibid.
     The Stiftung “exists for the benefit of those
    named in its formation documents as being appointed as beneficiaries.”

    Enelre Foundation as something other than a trust for US tax purposes,”
    which was “not easy.”
    In 2013, Daphne Jeanette Rost, Rebold’s daughter and power of
    attorney, filed a Form 3520 for 2005 on Rebold’s behalf, reporting that he
    owned a portion of Enelre and had transferred money to it. Rost also filed
    Forms 3520-A for the years 2005, 2006, and 2007, reporting year-end
    balances of $1,680,272, $1,807,873, and $3,116,898, respectively.
    In 2014, the IRS assessed $1,380,252.35 in penalties against Rebold
    under section 6677(a) and (b) for his failure to timely file Forms 3520 and to
    ensure that Enelre timely filed Forms 3520-A in 2005, 2006, and 2007. The
    IRS soon notified Rebold of its intent to levy the penalties. Rebold contested
    his liability and requested collection due process hearings. The IRS Appeals
    Office sustained the levy notices but cut the penalties in half. In June 2017,
    Rebold paid the penalties, as adjusted. In August 2018, he filed administrative
    refund claims with the IRS.
    C.
    In June 2019, having not received a decision from the IRS, Rebold filed
    this action, seeking refunds for the penalties. Upon Rebold’s death in
    December 2019, Rost, his executor, substituted as plaintiff.
    After discovery, the parties cross-moved for summary judgment on
    Rebold’s liability. The government argued that federal tax law determines
    the classification of an entity as a trust for tax purposes and that, under a
    facts-and-circumstances test, Enelre qualified as a foreign trust. Rost argued
    that because no statute, regulation, or judicial decision provides that a
    Liechtensteinian Stiftung is a foreign trust for federal tax purposes, the
    penalties violated the government’s “duty of clarity when imposing
    sanctions,” the Administrative Procedure Act (APA), and the Due Process
    Clause.
    5
    No. 21-51064
    The court granted the government’s motion and denied Rost’s. Rost
    v. United States, No. 1:19-CV-0607-RP, 
    2021 WL 5190875
     (W.D. Tex. Sept.
    22, 2021). Applying a facts-and-circumstances test, the court held that Enelre
    qualified as a foreign trust based on its purpose and form, as stated in its
    organizing documents, and because it failed the tests for domestic trusts set
    forth in Treasury regulations. 
    Id. at *4
    . The court found that Rost submitted
    no evidence “demonstrating fact issues that would prevent [it] from
    determining that [Enelre] is a ‘foreign trust’ as a matter of law.” 
    Ibid.
     The
    court rejected Rost’s notice arguments, finding the statutory and regulatory
    frameworks were “sufficiently clear.” 
    Id. at *5
    , *7–9. Rost timely appealed.

    We review a summary judgment de novo. United States v. Bittner,

    no genuine dispute as to any material fact and the movant is entitled to
    judgment as a matter of law.” Fed. R. Civ. P. 56(a); see Anderson v. Liberty
    Lobby, Inc., 
    477 U.S. 242
    , 248 (1986). Once the movant satisfies this burden,
    the nonmovant “must present competent summary judgment evidence of
    the existence of a genuine [dispute] of fact.” Johnson v. World All. Fin. Corp.,
    
    830 F.3d 192

    inferences in its favor.” Bittner, 19 F.4th at 740 (citation omitted).

    III.
    At bottom, Rost argues that Rebold had insufficient notice that Enelre
    qualifies as a foreign trust for federal tax purposes. She contests the facts-
    and-circumstances test employed by the district court. She claims that
    applicable statutes, regulations, and case law do not clearly “connect[] the
    imposition of penalties for failure to file foreign trust information returns with
    respect to a Liechtenstein Stiftung.” She then argues the penalties violate the
    APA, the government’s “duty of clarity,” and due process.
    We disagree with each contention. We first outline the legal
    framework for classifying an arrangement as a foreign trust, then explain why
    Enelre qualifies as one, and then address Rost’s notice arguments.
    A.
    The classification of an organization “for federal tax purposes is a
    matter of federal tax law and does not depend on whether the organization is
    recognized as an entity under local law.” 
    Treas. Reg. § 301.7701-1
    (a).
    Sections    301.7701–2,     301.7701–3,       and   301.7701–4    determine     the
    classification of organizations recognized as separate entities, unless the IRC
    “provides for special treatment of that organization.” 
    Id.
     § 301.7701-1(b).
    Neither the IRC nor its regulations specifically classify or provide for special
    treatment of Stiftungen. Cf. id. § 301.7701-2(b)(8) (classifying Liechtenstein
    Aktiengesellschaften as corporations).
    Determining whether an arrangement is a foreign trust requires a two-
    step inquiry: (1) whether it is a trust under section 301.7701-4 or a business
    entity under sections 301.7701-2 or 301.7701-3, and (2) if it is a trust, whether
    it is a United States person (i.e., a domestic trust) or a foreign trust. See I.R.C.
    § 7701(a)(30)(E), (31)(B); 
    Treas. Reg. §§ 301.7701-1
    (a)–(b), (d), 301.7701-
    2(a), 301.7701-4(a), 301.7701-5(a), 301.7701-7.
    7
    No. 21-51064
    A “trust” in the IRC is an arrangement where “trustees take title to
    property for the purpose of protecting or conserving it for the beneficiaries.”
    
    Treas. Reg. § 301.7701-4
    (a). An arrangement generally qualifies as a trust if
    “the purpose of the arrangement is to vest in trustees responsibility for the
    protection and conservation of property for beneficiaries who cannot share in
    the discharge of this responsibility and, therefore, are not associates in a joint
    enterprise for the conduct of business for profit.” Ibid.; see also Frank Aragona
    Tr. v. Comm’r, 
    142 T.C. 165
    , 175 (2014).
    An arrangement’s purpose thus distinguishes a trust from other
    entities. “[A]ny entity recognized for federal tax purposes . . . that is not
    properly classified as a trust under § 301.7701–4” is a “business entity.”
    
    Treas. Reg. § 301.7701-2
    (a). Arrangements “known as trusts because the
    legal title to property is conveyed to trustees for the benefit of beneficiaries”
    may nevertheless not qualify as trusts under the IRC “because they are not
    simply arrangements to protect or conserve the property for the
    beneficiaries.” 
    Id.
     § 301.7701-4(b). “Business trusts,” for example,
    “generally are created by the beneficiaries simply as a device to carry on a
    profit-making business which normally would have been carried on through
    business organizations that are classified as corporations or partnerships
    under the [IRC].” Ibid.; see Petersen v. Comm’r, 
    148 T.C. 463
    , 475 n.8 (2017).
    In classifying an arrangement as a trust or other business entity for tax
    purposes, “there is no one rule or set formula,” and “[e]ach case must be
    decided upon its own particular facts.” Keating-Snyder Tr. v. Comm’r, 
    126 F.2d 860
    , 862 (5th Cir. 1942); see also Comm’r v. Horseshoe Lease Syndicate,
    
    110 F.2d 748
    , 749 (5th Cir. 1940) (“the facts of each case[] must control”).
    The seminal case is Morrissey v. Commissioner, 
    296 U.S. 344
     (1935). There,
    the Supreme Court held that a trust created for developing tracts of land and
    constructing and operating a golf course was properly classified and taxed as
    “an association” (i.e., a business trust), rather than an ordinary trust, based
    8
    No. 21-51064
    on its “character” and “salient features,” including the trustees’ “use and
    adaptation of the trust mechanism.” 
    Id.
     at 359–61. The Court applied
    Morrissey’s fact-specific approach in three companion cases decided that
    same day. See Swanson v. Comm’r, 
    296 U.S. 362
     (1935); Helvering v. Coleman-
    Gilbert Assocs., 
    296 U.S. 369
     (1935); Helvering v. Combs, 
    296 U.S. 365
     (1935).
    An arrangement’s most relevant features for tax-classification
    purposes are its “nature,” “purpose,” and “operations.” Morrissey, 
    296 U.S. at 357
    ; Swanson, 
    296 U.S. at 365
    . 5 The form of organization under which
    the arrangement operates “may furnish persuasive evidence” of a
    classification but “cannot be regarded as decisive.” Morrissey, 
    296 U.S. at 358
    . No feature is dispositive; they “all go to the point of whether the trust is
    being used to achieve the organizational conveniences of the corporate
    form.” Guar. Emps. Ass’n v. United States, 
    241 F.2d 565
    , 571 (5th Cir. 1957).
    In assessing these features, the arrangement’s organizing documents
    are determinative. See Swanson, 
    296 U.S. at
    363–65; Morrissey, 
    296 U.S. at
    360–61. As the Supreme Court has explained, “parties are not at liberty to
    say that their purpose was other or narrower than that which they formally
    set forth in the instrument under which their activities were conducted.”
    Coleman-Gilbert, 
    296 U.S. at 374
    . 6
    5
    Morrissey relied on five corporate features to conclude the trust was “analogous
    to a corporate organization” and thus qualified as an “association,” or “business trust.”
    296 U.S. at 359–61. These features are “(1) title to the property held by the entity,
    (2) centralized management, (3) continuity uninterrupted by deaths among the beneficial
    owners, (4) transfer of interest without affecting the continuity of the enterprise, and
    (5) limitation of the personal liability of participants.” Comm’r v. Rector & Davidson, 
    111 F.2d 332
    , 333 (5th Cir. 1940); see Kurzner v. Comm’r, 
    413 F.2d 97
    , 101–04 & n.22 (5th Cir.
    1969) (reviewing Morrissey’s discussion of “distinguishing attributes of ‘corporateness’”).

    See also Abraham v. United States, 
    406 F.2d 1259

    out” in the trust instrument could not “be negated by [a] self-serving limiting declaration
    9
    No. 21-51064
    Once an entity is deemed a trust, it must be classified as foreign or
    domestic. A foreign trust is “any trust other than a trust” that is a “United
    States person” (i.e., a domestic trust). I.R.C. § 7701(a)(30)(E), (31)(B);
    
    Treas. Reg. § 301.7701-7
    (a)(2). A trust is domestic if (1) “a court within the
    United States is able to exercise primary supervision over the administration
    of the trust” (the “court test”) and (2) “one or more United States persons
    have the authority to control all substantial decisions of the trust” (the
    “control test”). I.R.C. § 7701(a)(30)(E); 
    Treas. Reg. § 301.7701-7
    (a)(1).
    A trust satisfies the court test if the governing document “does not
    direct that the trust be administered outside of the United States,” “[t]he
    trust in fact is administered exclusively in the United States,” and “[t]he
    trust is not subject to an automatic migration provision” that would move it
    outside the U.S. if a U.S. court were to “attempt to assert jurisdiction” over
    it. 
    Treas. Reg. § 301.7701-7
    (c)(1), (4)(ii). As to the control test, “control
    means having the power, by vote or otherwise, to make all of the substantial
    decisions of the trust, with no other person having the power to veto [them].”
    
    Id.
     § 301.7701-7(d)(1)(iii). This includes anyone with authority over
    substantial decisions, not only trust fiduciaries. Ibid. Substantial decisions are
    those “authorized or required” under the trust instrument and applicable
    law “that are not ministerial.” Id. § 301.7701-7(d)(1)(ii) (providing
    examples).

    accordingly legally be inferred . . . from the enumeration in the instrument of powers
    which, if exercised, would necessarily cause such an enterprise to result.”); Sears v. Hassett,
    
    111 F.2d 961
    , 962–63 (1st Cir. 1940) (noting the “character of the trust” is determined by
    “the purposes and potential activities as disclosed on the face of the trust instrument”).
    10
    No. 21-51064
    B.
    The district court correctly found that Enelre qualifies as a foreign
    trust. Its organizing documents explain that Enelre’s purpose is to support
    its beneficiaries and limit its transactions to “pursuing and realising its
    purpose.” This is “characteristic of an ordinary trust.” Morrissey, 296 U.S.
    at 356–57. The documents also prohibit Enelre from conducting commercial
    trade. Liechtensteinian Public Registry filings confirm this prohibition.
    Enelre’s familial purpose, lack of business objective, and bar on commercial
    activity render it a trust. See McKean v. Scofield, 
    108 F.2d 764
    , 765–66 (5th
    Cir. 1940) (holding a trust was taxable as a trust and not an association
    because “[s]olicitude for the future of [the settlor’s] family [wa]s a main
    purpose of the trust”); see also Estate of Bedell v. Comm’r,

    purpose). 7
    Enelre’s form of organization confirms it is a trust. Enelre is subject
    to Liechtenstein’s “Act on Trust Enterprises.” Its board members serve the
    same function as independent trustees, and Enelre’s counsel considered
    them trustees. Enelre also has beneficiaries like an ordinary trust. Rebold
    described himself as “Settlor and Beneficiary” of Enelre, and he transferred
    money to Enelre the same way a trust grantor would. Rebold’s children, the
    other beneficiaries, were not involved with Enelre and did not know it existed
    during the years in question, so they could not have been “associates”

    ; cf.
    Elm St. Realty Tr. v. Comm’r, 
    76 T.C. 803
    , 813–18 (1981). And Enelre’s
    organizing documents do not provide for profit sharing. See Morrissey, 
    296 U.S. at 357
    .
    Enelre is not a domestic trust. It fails the court test because any
    disputes must proceed to arbitration under Liechtensteinian law, with “the
    President of the Princely Liechtenstein Court of Appeal” assisting in
    appointing an arbitrator. See I.R.C. § 7701(a)(30)(E)(i); 
    Treas. Reg. § 301.7701-7
    (a)(1)(i), (c)(1). And it fails the control test because Rebold, as
    settlor, “waive[d] any influence on [Enelre] and on any other rights
    whatsoever towards [Enelre], [its] board, and the beneficiaries,” and
    Enelre’s       board   has    decision-making      authority.     See    I.R.C.
    § 7701(a)(30)(E)(ii); 
    Treas. Reg. § 301.7701-7
    (a)(1)(ii), (d)(1)(i)–(iii).
    Failing both tests, Enelre is not a domestic trust and so qualifies as a foreign
    trust. See I.R.C. § 7701(a)(30)(E), (31)(B); 
    Treas. Reg. § 301.7701-7
    (a)(1)–
    (2); see also Kaplan v. Comm’r, 
    107 T.C.M. (CCH) 1226
    , 
    2014 WL 988465
    ,
    at *7 (Mar. 13, 2014) (holding trusts “organized under the laws of the Isle of
    Jersey and supervised by the Royal Court of Jersey[] are foreign trusts”).
    Rost argues that because the IRC and its regulations do not specifically
    classify Liechtensteinian Stiftungen as trusts, they could be corporations,
    partnerships, or other entities. They very well could, under certain facts and
    circumstances. But Rost presents no evidence that Enelre should be classified
    as anything other than a trust. See, e.g., Jones v. United States, 
    936 F.3d 318
    ,
    321 (5th Cir. 2019) (“A non-movant will not avoid summary judgment by
    presenting ‘speculation, improbable inferences, or unsubstantiated
    assertions.’” (citation omitted)).
    Rost also claims that courts have treated a Stiftung as a corporation
    under the IRC, citing Oak Commercial Corp. v. Commissioner, 
    9 T.C. 947
    12
    No. 21-51064
    (1947), aff’d sub nom. Aramo-Stiftung v. Commissioner, 
    172 F.2d 896
     (2d Cir.
    1949). But there, neither the Tax Court nor the Second Circuit evaluated
    whether the Stiftungen were properly characterized as foreign corporations.
    The Tax Court merely accepted the IRS’s position that the Stiftungen were
    corporations because the taxpayer failed to challenge the classification. See
    Oak Commercial, 
    9 T.C. at 954
    –55. Accordingly, the treatment of the
    Stiftungen there is unhelpful. See Estate of Swan v. Comm’r, 
    247 F.2d 144
    , 147
    n.3 (2d Cir. 1957); Estate of Swan v. Comm’r, 
    24 T.C. 829
    , 860 (1955).
    C.
    Rost’s notice arguments are without merit. Rost first claims the
    penalties violate the APA because the government relied on an unwritten
    “rule” promulgated without notice and comment that Stiftungen are foreign
    trusts for tax purposes. But the government applied no “rule.” See 
    5 U.S.C. § 551
    (4) (defining “rule”). As the district court explained, “Rost’s argument
    is based on the faulty premise that the IRS established a ‘rule’ that a Stiftung
    always qualifies as a ‘foreign trust.’” Rost, 
    2021 WL 5190875
    , at *8. The IRS
    has consistently recognized that each Stiftung must be analyzed on its own
    facts and circumstances. See, e.g., I.R.S. Chief Couns. Att’y Mem. AM2009-
    012, 
    2009 WL 3336014
     (Oct. 7, 2009). Rost does not challenge the validity of
    the regulations under which Enelre qualifies as a foreign trust. See 
    Treas. Reg. §§ 301.7701-4
    , 301.7701-7.
    Rost next argues the penalties “violate[] the duty of clarity for tax
    laws,” citing Central Illinois Public Service Co. v. United States, 
    435 U.S. 21
    (1978). She claims the penalties cannot be imposed “without a clear
    description of the prohibited circumstances, facts, or status.” This
    argument, too, is based on the false “presumption that the IRS automatically
    considers a Stiftung to be a foreign trust for tax and penalty purposes.” Rost,
    
    2021 WL 5190875
    , at *8.
    13
    No. 21-51064
    Rost claims there is “no indication which foreign entities” the
    government “might deem to be a foreign trust.” But the IRS is not obligated
    to promulgate a regulation listing all foreign entities that are or may be
    classified as a foreign trust. As Morrissey acknowledged, “it is impossible in
    the nature of things to translate the statutory concept of ‘association’ into a
    particularity of detail that would fix the status of every sort of enterprise or
    organization which ingenuity may create.” 296 U.S. at 356. So too for trusts.
    In any event, Central Illinois is inapposite. There, the Court held an
    employer could not be penalized for failing to withhold income taxes on
    reimbursements of meal expenses for employees day-traveling on business
    because it was unclear at the time that the meals constituted wages subject to
    withholding. 
    435 U.S. at 29, 33
    . Rost identifies no decision applying this logic
    outside third-party withholding contexts. Cf. 
    id. at 31
     (“Because the
    employer is in a secondary position as to liability for any tax of the employee,
    it is a matter of obvious concern that . . . the employer’s obligation to
    withhold be precise and not speculative.”). 8 But even if it applied here, the
    legal framework set forth above is sufficiently precise.
    Finally, Rost argues that the penalties violate due process because
    there is no “clear, written rule of law” that Stiftungen qualify as foreign
    trusts. As shown above, the IRC, regulations, and case law provide ample
    notice that the classification of an arrangement as a trust, and whether it is
    8
    This defense has been dubbed the “‘deputy tax collector’
    defense, . . . protect[ing] an employer from liability for failing to withhold employment
    taxes from its employees when the employer lacks ‘precise and not speculative’ notice of
    its duty to withhold.” N.D. State Univ. v. United States, 
    255 F.3d 599
    , 608 (8th Cir. 2001)
    (quoting Cent. Ill., 
    435 U.S. at 31
    ); see also Univ. of Chi. v. United States, 
    547 F.3d 773
    , 784
    (7th Cir. 2008); Gen. Elevator Corp. v. United States,

    The district court’s judgment is AFFIRMED.

    Rost also claims there was no statutory authority to penalize Rebold for failing to
    file Form 3520-A before the 2010 amendment to section 6677. We decline to consider this
    argument because Rost did not raise it below. See, e.g., Rollins v. Home Depot USA, 
    8 F.4th 393
    , 397–99 (5th Cir. 2021); Doe v. MySpace, Inc., 
    528 F.3d 413
    , 422 (5th Cir. 2008).
