    Opinion for the Court filed by Circuit Judge HENDERSON.
    KAREN LECRAFT HENDERSON, Circuit Judge: In January
    2008, the Commissioner of the Internal Revenue Service
    (Commissioner) issued tax adjustments to the partnership of
    BCP Trading & Investments, LLC (BCP) for tax years 2000
    and 2001. Members of BCP—themselves limited
    partnerships—challenged the adjustments, arguing they were
    untimely and that the Commissioner mistakenly determined
    that the investment partnership was a sham. The United States
    Tax Court found the adjustments timely because the three-year
    statute of limitations for the adjustments was extended by the
    partnership and its members and those extensions, contrary to
    BCP’s members’ challenges, were consistent with fiduciary
    and contract principles. The Tax Court upheld the
    Commissioner’s adjustments, declaring the partnership a sham
    for tax purposes. Virginia Simpson, a non-participating party,
    moved to intervene after the Tax Court issued its memorandum
    opinion and findings of fact but before it issued its final
    decisions. The Tax Court denied her intervention in a separate
    order.
    Before us is a consolidated appeal of the Tax Court’s
    opinion and final decisions regarding the Commissioner’s
    adjustments issued to BCP as well as its order denying
    intervention. The Tax Court applied correct legal precedent and
    committed no clear error in its findings upholding the
    3
    Commissioner’s tax adjustments. Nor did the Tax Court abuse
    its discretion in denying Simpson’s intervention. Accordingly,
    we affirm.
    I.     BACKGROUND1
    As with many cases arising from the Tax Court, “[t]he
    hardest aspect of this case is simply getting a handle on the
    facts.” ASA Investerings P’ship v. Comm’r, 
    201 F.3d 505
    , 506
    (D.C. Cir. 2000). Because a chronological retelling of the story
    may confuse more than enlighten, we start with the actors
    involved and then address the intricacies of the transaction at
    issue.
    A. The Actors
    The hub around which all of the actors revolve is BCP.
    BCP was a partnership and during its brief life had 39
    members. At BCP’s helm was its managing member, a limited
    liability company, Bolton Capital Planning, LLC (Bolton
    Capital). Charles Bolton owned and operated Bolton Capital
    and Belle Six worked for Bolton Capital. Six, Bolton’s partner
    in crime,2 was a former employee of the global accounting firm
    Ernst & Young (E&Y). BCP’s other 38 members (“client
    members”) were limited liability companies and limited
    partnerships and all were clients of E&Y. Two groups of client
    members—all limited partnerships—are relevant to this
    appeal: (1) KP1, KP2 and PCMG XII and (2) WTETP and
    PCMG VI.
    1
    We address the relevant facts and law of Simpson’s failed
    intervention in Part III, infra at 31. All facts come from the
    stipulations and other evidence before the Tax Court.
    2
    Six and Bolton both pleaded guilty to tax crimes in connection
    with their tax shelter activities.
    4
    Kevin Kalkhoven and Dan Pettit were limited partners in
    the KP1, KP2 and PCMG XII limited partnerships. They were
    both executives at JDS Uniphase Corporation and they hired
    E&Y in the 1990s to manage their tax matters. Their
    relationship with E&Y grew from tax matters to include much
    of their personal financial affairs. Jim Cox of E&Y managed
    both Kalkhoven’s and Pettit’s business matters.
    William Esrey was a limited partner in WTETP and
    Ronald LeMay was a limited partner in PCMG VI. Esrey and
    LeMay were executives at Sprint Corporation; Sprint required
    them to use E&Y to prepare their tax returns and E&Y prepared
    their tax returns beginning in the 1980s. Over the years both
    Esrey’s and LeMay’s relationship with E&Y evolved from tax
    preparation to estate, financial and tax planning—Mike Carr of
    E&Y served as Esrey’s and LeMay’s point of contact.
    B. The Actors’ Business Relationships
    In 1999 Six left E&Y to join The Private Capital
    Management Group (TPCMG) to help TPCMG market an
    E&Y-promoted financial transaction called a Contingent
    Deferred Swap (CDS). CDS transactions defer taxes on
    ordinary income by one year and transform the ordinary
    income into capital gains, which are taxed at a lower rate than
    ordinary income. Through their respective limited
    partnerships, Kalkhoven, Pettit, Esrey and LeMay (Taxpayers)
    engaged in CDS transactions with TPCMG in 1999. In late
    1999 or early 2000, TPCMG transferred the CDS business to
    Bolton. Six joined Bolton to continue to market the CDS
    transactions and act as liaison between Bolton and E&Y.
    To offset the capital gains taxes generated from the CDS
    transactions, E&Y created a new transaction—the transaction
    at issue in this case—known as the CDS Add-On or CDS Plus
    (Add-On). E&Y’s Carr and Bolton Capital’s Six described the
    5
    Add-On to Esrey and LeMay and both Esrey and LeMay
    decided to participate. E&Y and Bolton Capital’s Six also
    presented the Add-On to Kalkhoven and Pettit and both
    decided to participate. In May 2000, on E&Y’s advice, Bolton
    Capital formed BCP to execute the Add-On. Between 2000 and
    2001 BCP client members—including the Taxpayers’ limited
    partnerships—engaged in the E&Y-designed Add-On.
    Under the United States Tax Code, partnerships do not pay
    federal income tax. I.R.C. § 701.3 Instead, partnerships file an
    annual information return reporting each partner’s share of
    income, gain, loss, deductions and credits. Id. §§ 702, 6031.
    The partners report their individual shares of income, gain,
    loss, deduction or credit on their individual federal income tax
    returns and taxes are assessed against the partners individually.
    Id. §§ 701, 702, 704. If the IRS disagrees with a partnership’s
    reporting, it issues a Final Partnership Administrative
    Adjustment (FPAA) before imposing tax assessments against
    the individual partners. Id. §§ 6223(a)(2), (d)(2), 6225(a). The
    IRS must assess tax attributable to partnership items 4 within
    three years of the date the partnership return is filed or the last
    date for filing the return, whichever is later. Id. § 6229(a). If
    the three-year period has not yet expired, the IRS may seek to
    extend it, using either of two “statute extensions.” Id.
    3
    Unless otherwise noted, references to the Internal Revenue
    Code are those in effect at the time relevant to these cases.
    4
    A “partnership item” is “any item required to be taken into
    account for the partnership’s taxable year under any provision of [the
    Internal Revenue Code’s Income Tax subtitle] to the extent
    regulations prescribed by the Secretary provide that, for purposes of
    this subtitle, such item is more appropriately determined at the
    partnership level than at the partner level.” I.R.C. § 6231(a)(3). “[A]
    determination that a partnership lacks economic substance is an
    adjustment to a partnership item.” United States v. Woods, 
    571 U.S. 31
    , 39 (2013).
    6
    § 6229(b). The IRS may obtain an extension from the partner
    whose individual tax return may be affected. Id.
    § 6229(b)(1)(A). Alternatively, the IRS may ask the tax matters
    partner (TMP) of the partnership to consent to an extension to
    allow the IRS to assess any taxes attributable to partnership
    items of all partners. Id. § 6229(b)(1)(B).
    The IRS obtained a timely partnership extension for tax
    year 2000 from Bolton, BCP’s TMP, on January 6, 2004
    (Partnership Extension). Bolton subsequently executed eight
    more partnership extensions—the last on April 2, 2007—
    extending the liability period for tax years 2000 and 2001
    through June 30, 2008. The IRS also obtained timely individual
    extensions from Kalkhoven, Pettit, Esrey and LeMay
    (Individual Extensions). As relevant here, Pettit and Kalkhoven
    signed Individual Extensions for tax year 2000 on November
    17 and November 20, 2003, respectively, and both again did so
    on September 27, 2004. Esrey and LeMay signed Individual
    Extensions for tax year 2000 on December 4, 2003 and January
    26, 2004, respectively. The Taxpayers continued to sign
    individual extensions, extending their tax liability for tax years
    2000 and 2001 through at least December 31, 2008.
    While the IRS sought the Partnership and Individual
    Extensions, E&Y was actively advising BCP and the
    Taxpayers and representing the Taxpayers before the IRS.
    E&Y’s Cox advised Kalkhoven and Pettit to consent to the
    Individual Extensions and did not discuss any extension
    downside with them. Similarly, E&Y’s Carr advised Esrey and
    LeMay to authorize individual extensions. E&Y also advised
    BCP to sign the Partnership Extension. Six wrote to the
    Taxpayers, informing them that Bolton Capital planned to sign
    the Partnership Extension “[b]ased on Ernst & Young’s . . .
    recommendation . . . unless we hear otherwise from you.” Joint
    Appendix (J.A.) 725.
    7
    Around the same time E&Y was the subject of several civil
    and criminal investigations. As a brief overview, by 2002 E&Y
    knew the IRS was auditing CDS transactions. In March 2002,
    E&Y became the subject of an IRS “civil promoter” audit to
    determine if E&Y had failed to disclose tax shelters.5 That
    audit was settled in July 2003. In May 2004, a grand jury
    investigation began to examine E&Y’s tax shelters.
    On January 31, 2008, the IRS issued FPAAs against BCP
    for tax years 2000 and 2001. In the FPAAs, the IRS determined
    BCP was a “sham” and should be disregarded for tax purposes.
    The Taxpayers, through their partnerships, challenged the
    FPAAs in Tax Court. First, the Taxpayers argued the FPAAs
    for tax year 2000 were untimely because the Individual
    Extensions and Partnership Extension upon which any
    subsequent tax year 2000 extensions rested were voidable
    under agency and contract law. The Taxpayers also argued that
    BCP was a bona fide partnership because it had a valid business
    purpose. In August 2013 Tax Court Judge Diane Kroupa
    presided over the trial but Judge Kroupa retired after trial and
    the case was reassigned to Tax Court Judge Mark Holmes. In
    August 2017 the Tax Court issued its findings of fact and
    memorandum opinion, concluding the extensions were valid
    and that BCP “was created to carry out a tax-avoidance
    scheme” and should therefore be “disregard[ed]” for tax
    purposes. BCP Trading & Invs., LLC v. Comm’r, 
    114 T.C.M. (CCH) 151
    , 
    2017 WL 3394123
    , at *21 (2017). On February 6,
    2019, the Tax Court issued its order denying intervention. J.A.
    5
    I.R.C. §§ 6111 and 6112 require a tax shelter organizer to
    register a qualifying tax shelter with the IRS and provide certain
    information regarding it. I.R.C. §§ 6707 and 6708 impose penalties
    on anyone who fails to register or provide the applicable information
    on a qualifying tax shelter.
    8
    2482. And on February 7, 2019, it issued two decisions
    implementing its August 2017 opinion. J.A. 2488–89.
    C. The Challenged Add-On6
    The Add-On consisted of several intermediate steps. To
    begin, BCP client members purchased 132 option pairs
    between July 19 and August 11, 2000. Both options in the pair
    were digital options. A digital option is a type of option
    contract that pays the option holder a fixed payout if the
    underlying asset’s price equals or exceeds a predetermined
    price (strike price) by a predetermined expiration date.7 If the
    underlying asset’s price does not reach the strike price by the
    expiration date, the option expires worthless. Here, the
    underlying asset in each digital option pair was a foreign
    currency.
    As a “European-style” option, the underlying asset’s price
    is evaluated to determine whether an option pays out or expires
    worthless only on the predetermined expiration date and time.
    The asset’s price at expiration is the spot price or spot rate.
    Accordingly, on the option’s expiration date and time, the spot
    price is compared to the strike price. If the spot price meets or
    exceeds the strike price, the option pays out but if the spot price
    does not meet or exceed the strike price, the option expires
    worthless. All options began “out of the money”—at the time
    each option was purchased, the currency price did not already
    6
    Our description of the Add-On follows the Commissioner’s
    brief, see Appellee’s Br. at 4–26, and the Tax Court’s opinion, see
    BCP, 
    2017 WL 3394123
    , at *3–*6.
    7
    Here, we describe the 124 option pairs that required positive
    price movement relative to the strike price, not the eight option pairs
    that required negative price movement.
    9
    exceed the strike price but upward price movement was
    necessary for them to pay out and not expire worthless.
    Each option pair included an option which the client
    member bought from Refco Capital Markets (Refco) (referred
    to as the “long” option) and an option which the client member
    sold to Refco (referred to as the “short” option). The long and
    short options in each pair had a one “percentage in point” (pip)
    difference in strike price. A pip is the smallest pricing
    increment in foreign exchange markets and for many
    currencies it is 1/100th of a cent. With a spread only one pip
    wide, typically the spot prices fall short of both strike prices
    (and both options in the pair expire worthless) or exceed both
    strike prices (and both options in the pair pay out). As
    envisioned, if the spot price exceeded both strike prices, Refco
    owed the predetermined payout on the long option to the client
    member and the client member owed the predetermined payout
    on the short option to Refco. But the payout to the client
    member on the long option always exceeded the payout to
    Refco on the short option; Refco then paid the client member
    the difference between the two. Accordingly, if both options
    expired “in the money” with the spot price above the strike
    price, only the client member (not Refco) received the net
    payout.
    How the Add-On functioned may be best understood by
    one transaction. PCMG XII bought and sold into an option pair
    with Refco on July 31, 2000. Both the long and short options
    in the pair expired on November 30, 2000. The option pair’s
    underlying asset was the reference exchange rate of Canadian
    Dollars (CAD) per United States Dollar (USD). The long
    option’s strike price was an exchange rate of 1.5075 and the
    short option’s strike price was an exchange rate of 1.5076. If
    the spot price (i.e., the reference exchange rate on November
    30, 2000) equaled or exceeded the long option’s strike price of
    10
    1.5075, Refco paid PCMG XII $170 million. On the other
    hand, if the spot rate equaled or exceeded the short option’s
    strike price of 1.5076, PCMG XII paid Refco $169.5 million.
    If the spot rate was above both strike prices, PCMG XII
    received a net payment of $500,000. If the spot price was below
    both strike prices, both options expired worthless.
    If the spot rate landed within the one pip spread—the
    “sweet spot”—client members received a “lottery payoff”
    because Refco had to pay out on the long option but the client
    members did not have to pay out on the short option. In our
    example, if the spot rate had landed at 1.5075 or between
    1.5075 and 1.5076, Refco would have paid PCMG XII $170
    million but PCMG XII would not have paid Refco $169.5
    million. The likelihood of the spot rate falling within the one
    pip spread was miniscule. Not only was the spread just one pip
    wide but the option pairs were custom. A custom option is not
    listed or traded on any exchange. Accordingly, there are
    multiple different expiration-day spot prices for the same
    currency depending on which bank or broker Refco dealt with.
    Refco had the discretion to choose between those spot prices
    for settling the option pairs, so long as it acted “in good faith
    and in a commercially reasonable manner.” J.A. 90. Refco had
    both an incentive not to let an option pair hit the sweet spot and
    the discretion to keep it from doing so.8
    8
    Refco’s incentive to enter the option pair contracts came from
    the option premiums. The client members paid a purchase premium
    to Refco on each long option and Refco paid a sale premium to the
    client members on each short option. The purchase premium
    exceeded the sale premium and the client members paid Refco the
    net difference between the premiums (total premium). In our
    example, PCMG XII’s purchase premium to Refco was $51,000,000.
    Refco’s sale premium to PCMG XII was $50,750,787. Accordingly,
    11
    Between July 31 and August 11, 2000, the client members
    contributed the option pairs to BCP—transferring the assets
    from the client member’s ownership to BCP’s. In return, each
    client member was credited with a BCP capital account equal
    to the amount of the total premium paid on its contributed
    options. Subsequently, every option pair either expired
    worthless or was sold before its expiration date for less than the
    total premium paid. Accordingly, BCP’s portfolio appeared to
    lose significant value.
    E&Y advised the client members to terminate their interest
    in BCP in the year they chose to claim losses. All client
    members, including the Taxpayers’ respective partnerships,
    withdrew from BCP between 2000 and 2001. Upon leaving
    BCP, client members, including the Taxpayers, were paid in
    Japanese yen in an amount equal to their remaining capital
    account less expenses and fees. A client member triggered its
    losses by liquidating its position in BCP and selling the yen.
    Client members claimed an outside basis9 in their yen of
    an amount equal to the assets they contributed to BCP—their
    long option premiums—but did not reduce the basis by
    contingent liabilities BCP assumed—their short options.
    Because the short option liabilities were not fixed at the time
    of transfer—they were out of the money and there was not an
    obligation to pay on them unless, at expiration, they were in the
    money—the partnership treated them as uncertain and ignored
    them in computing the partners’ outside bases. Accordingly,
    PCMG XII paid Refco the total premium: $249,213. Whether the
    options expired worthless or paid out, Refco kept the total premium.
    9
    “Outside basis” is “[a] partner’s tax basis in a partnership
    interest.” Woods, 571 U.S. at 35–36. Outside basis “functions as a
    proxy for the value of the assets . . . contributed” to a partnership.
    Petaluma FX Partners, LLC v. Comm’r, 
    792 F.3d 72
    , 75 (D.C. Cir.
    2015).
    12
    when the Taxpayers sold their yen, it appeared they had
    sustained massive losses. For example, after liquidating its
    interest in BCP, PCMG XII received $478,748 worth of yen.
    PCMG XII claimed a basis of $709,108,965—PCMG XII’s
    long option premiums—in the yen. That is, PCMG XII claimed
    the value of the assets it contributed to BCP was $709,108,965,
    notwithstanding PCMG XII had paid a total premium of only
    $3,354,857 for the option pairs it contributed to BCP. When
    PCMG XII sold its yen—representing all that remained of the
    assets PCMG XII had contributed to BCP—it appeared that the
    value of the assets PCMG XII had contributed to BCP
    decreased from over $700 million to $478,748. The Taxpayers
    then used the losses generated from the Add-On to
    substantially offset their income and reduce their taxes.10
    After the 2001 distributions, BCP had no assets or
    liabilities, its only remaining member was its managing
    member, Bolton Capital, and BCP dissolved in June 2002. The
    Commissioner contends the Add-On is a type of tax shelter
    known as a Son-of-BOSS shelter, described by the Tax Court
    as a series of steps whereby the taxpayers
    transfer . . . assets encumbered by significant
    liabilities to a partnership, with the goal of
    increasing basis in that partnership. The
    10
    For example, for the tax year 2000, Kalkhoven reported
    salary income of $492,523,171 and capital gains of $35,399,233 but
    claimed combined losses of $533,578,758 from the three
    partnerships, reducing his federal tax liability to $2,746,074. In other
    instances, the Taxpayers even received tax refunds in the millions of
    dollars. For tax year 2000, the Esreys reported salary income of
    $83,724,716 and capital gains of $123,058,888 but, using a total loss
    of $462,205,971 from the partnerships, reduced their tax liability to
    $14,446 attributable to self-employment taxes, which resulted in a
    $5,261,538 refund.
    13
    liabilities are usually obligations to buy
    securities, and typically are not completely
    fixed at the time of transfer. This may let the
    partnership treat the liabilities as uncertain,
    which may let the partnership ignore them in
    computing basis. If so, the result is that the
    partners will have a basis in the partnership so
    great as to provide for large—but not out-of-
    pocket—losses on their individual tax returns.
    BCP, 
    2017 WL 3394123
    , at *1 n.2. As explained infra, the Tax
    Court agreed with the Commissioner’s contention.
    II. ANALYSIS
    Tax Court decisions are reviewed “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). Accordingly,
    questions of law are reviewed de novo and factual findings for
    clear error. Andantech LLC v. Comm’r, 
    331 F.3d 972
    , 976
    (D.C. Cir. 2003). Mixed questions of law and fact are treated
    as questions of fact and reviewed for clear error. 
    Id.
     Under clear
    error review, we assess the Tax Court’s findings under “all the
    evidence of record,” Daniels v. Hadley Mem’l Hosp., 
    566 F.2d 749
    , 757 (D.C. Cir. 1977), and “may overturn the Tax
    Court’s . . . findings only if we come to a ‘definite and firm
    conviction that a mistake has been committed,’” Endeavor
    Partners Fund, LLC v. Comm’r, 
    943 F.3d 464
    , 467 (D.C. Cir.
    2019) (quoting United States v. U.S. Gypsum Co., 
    333 U.S. 364
    , 395 (1948)). Clear error occurs if a finding is based on a
    “serious mistake as to the effect of evidence or is clearly
    contrary to the weight of the evidence.” Daniels, 
    566 F.2d at 757
     (footnotes omitted).
    The Taxpayers first argue the Tax Court clearly erred in its
    ruling that the extensions were valid because the Tax Court
    14
    misunderstood the facts and failed to apply them under the
    correct legal standards. Next, the Taxpayers challenge the Tax
    Court’s sham determination because it allegedly applied an
    incorrect legal standard and clearly erred in its fact-finding.
    Granted, the Tax Court opinion is at times unclear or its
    reasoning is cursory. But such flaws do not per se establish
    clear error. See ASA Investerings P’ship v. Comm’r,

    although some “reasoning seem[ed] misdirected” and at times
    its “focus . . . was a little puzzling”). Viewing the record as a
    whole, we cannot come to a “definite and firm conviction that
    a mistake has been committed,” U.S. Gypsum Co., 
    333 U.S. at 395
    , nor do we conclude that the Tax Court applied an incorrect
    legal standard.11
    A. The Statute Extensions
    In Tax Court, the Taxpayers argued that the January 2004
    Partnership Extension and the 2003/2004 Individual
    Extensions were voidable under fiduciary and contract law;
    further, the limitations period governing adjustments for the
    2000 tax year expired before the adjustments issued because
    extensions for that year were obtained outside the three-year
    11
    We recognize that “the presumption of correctness that
    attaches to factual findings is stronger in some cases than in others.”
    Bose Corp. v. Consumers Union of U.S., Inc., 
    466 U.S. 485
    , 500
    (1984). Even though the presumption may have “lesser force” here
    because Judge Holmes was not the trial judge and his “findings
    [were] based on documentary evidence,” not live testimony, our
    determination      remains     unaffected.     
    Id.
       Judge     Holmes

    Procedure] 63’s basic requirement: that a successor judge become

    166 F.3d 1257
    , 1265 (D.C.
    Cir. 1999).

    limitations period. An FPAA is timely if either an individual
    extension or the Partnership Extension is valid. The Taxpayers’
    arguments that the extensions are void start from the same
    general proposition: when the IRS sought the Partnership
    Extension and Individual Extensions, E&Y had a conflict of
    interest due to the civil and criminal investigations it was
    facing, E&Y breached its duty to the Taxpayers because E&Y
    never disclosed that conflict and the IRS ignored and facilitated
    E&Y’s breach—ultimately benefitting from the breach by
    securing the extensions. The Tax Court found that the
    Taxpayers’ arguments failed irrespective of any E&Y conflict
    or breach of duty to the Taxpayers. We agree with the Tax
    Court, as we now explain.
    1.    The Partnership Extension and Bolton’s Fiduciary Role
    Principles of agency and fiduciary law apply to extensions.
    See Transpac Drilling Venture 1982-12 v. Comm’r, 
    147 F.3d 221
    , 225 (2d Cir. 1998). And under fiduciary law, “the
    transactions of those who knowingly participate with [a]
    fiduciary in . . . a breach are ‘as forbidden’ as transactions ‘on
    behalf of the trustee himself.’” Dirks v. SEC, 
    463 U.S. 646
    , 659
    (1983) (quoting Mosser v. Darrow, 
    341 U.S. 267
    , 272 (1951));
    see also United States v. Dunn, 
    268 U.S. 121
    , 132 (1925) (“he
    who fraudulently traffics with a recreant fiduciary shall take
    nothing by his fraud”). Here, if the IRS knowingly trafficked
    with a breaching fiduciary to obtain the extensions, it cannot
    benefit from them.
    In concluding that the Partnership Extension is valid under
    fiduciary principles, the Tax Court focused on Bolton as the
    relevant fiduciary because he, not E&Y, signed the Partnership
    Extension as the Taxpayers’ fiduciary. BCP, 
    2017 WL 3394123
    , at *14. We find no fault in that focus. See In re
    Martinez, 
    564 F.3d 719
    , 735 (5th Cir. 2009) (“the IRS’s ability
    16
    to deal with a [TMP] and rely on his actions on behalf of the
    partnership is critical for the effective operation of the current
    tax system”). The transaction at issue was between Bolton—
    acting on behalf of the Taxpayers as their fiduciary—and the
    IRS.
    The Tax Court distinguished the facts sub judice from
    those in a leading Second Circuit case. BCP, 
    2017 WL 3394123
    , at *14 (citing Transpac, 
    147 F.3d at 221
    ). The issue
    in Transpac was “whether, as a result of being placed under
    criminal investigation by the IRS (and hence becoming subject
    to pressure by the IRS), the [TMPs] labored under a conflict of
    interest and thereby were disqualified from binding the
    partnerships.” 
    147 F.3d at 222
    . The IRS sought and obtained
    partnership extensions from the TMPs—who were at that time
    under criminal investigation—after the limited partners refused
    to sign individual extensions. 
    Id. at 224
    . The TMPs cooperated
    with the criminal investigation and were granted immunity or
    offered suspended sentences by the prosecution. 
    Id. at 223
    .
    Because the IRS knew the TMPs had a “powerful incentive to
    ingratiate themselves to the government,” they operated under
    disabling conflicts and the IRS could not rely on their consent
    to bind the limited partners. 
    Id. at 227
    .
    As the Tax Court recognized, this case is readily
    distinguishable from Transpac. Bolton, as the TMP, was not
    under criminal investigation at the time he signed the
    Partnership Extension. Apparently, Bolton did not begin to
    worry about potential criminal liability until two years after he
    signed the January 2004 Partnership Extension. Accordingly,
    the IRS had no reason to believe it was dealing with a breaching
    fiduciary when it obtained Bolton’s consent to the Partnership
    Extension. And unlike in Transpac, the Taxpayers did not
    rebuff the IRS’s request for individual extensions—in fact, all
    of the Taxpayers signed Individual Extensions. The Taxpayers
    17
    contend their agreement is tainted because they could not have
    made an informed decision as to any extension without
    knowing of E&Y’s conflict. But the Taxpayers’ acquiescence
    does inform whether the IRS had reason to know Bolton was a
    breaching fiduciary when it obtained the Partnership Extension
    from him.12
    2.    The Partnership and Individual Extensions and Contract
    Law
    Although a statute extension is not a contract, “[c]ontract
    principles are significant” in evaluating it because I.R.C.
    12
    The Taxpayers also argue the transaction between Bolton as
    their fiduciary and the IRS is invalid because the IRS dealt with E&Y
    in order to secure the Partnership Extension. But this argument
    would require E&Y’s authority to secure the Partnership Extension
    either through the Taxpayers or Bolton—and for the IRS to know
    that. Evidence suggests that Six solicited input from the Taxpayers
    on the Partnership Extension, J.A. 153–54, but there is no evidence
    the IRS knew that. And the Taxpayers’ focus on Bolton himself fails
    as well. Indeed, the Tax Court found the Taxpayers’ argument that
    E&Y “embedded” Six in BCP unconvincing because Six left E&Y
    for “messy personal reasons.” BCP, 
    2017 WL 3394123
    , at *14.
    Although the Tax Court’s finding is brief, we do not believe it clearly
    erred in finding E&Y did not have the influence to secure the
    Partnership Extension through Bolton or that the IRS knew of E&Y’s
    influence, if any. The communications between the IRS and E&Y
    regarding Bolton’s consent to the Partnership Extension are
    equivocal regarding E&Y’s influence over Bolton such that the IRS
    knew E&Y was the real party securing the extension. Compare J.A.
    815–16 (E&Y told the IRS it “request[ed]” Bolton to sign the
    Partnership Extension), with J.A. 560 (IRS agent noted E&Y partner
    said he “had the [TMP] designation signed and the statute
    extensions”). In our view, E&Y’s bare “request” of Bolton does not
    establish that the IRS knew that E&Y in fact had influence over
    Bolton.
    18
    § 6501(c)(4) “requires that the parties reach a written
    agreement as to the extension” and an agreement “means a
    manifestation of mutual assent.” Piarulle v. Comm’r, 80 T.C.
    (CCH) 1035, 1042 (1983). Accordingly, the Tax Court applies
    “general contract principles in interpreting, applying and
    deciding the enforceability of waiver documents.” Chai v.
    Comm’r, 
    102 T.C.M. (CCH) 520
    , 
    2011 WL 5600287
    , at *2
    (2011).
    The Taxpayers argue that the challenged extensions are
    invalid under the contract principles of misrepresentation and
    undue influence. Generally, misrepresentation is “an assertion
    that is not in accord with the facts” or a material non-disclosure.
    Restatement (Second) of Contracts §§ 159, 161. And undue
    influence is the “unfair persuasion of a party . . . who by virtue
    of the relation between [the party and the persuader] is justified
    in assuming that [the persuader] will not act in a manner
    inconsistent with his welfare.” Id. § 177(1). The extent of
    unfair persuasion “depends on a variety of circumstances,”
    including the “unavailability of independent advice.” Id.
    cmt. b. A contract is voidable if a party’s manifestation of
    assent is induced by a non-party’s misrepresentation or undue
    influence unless the counterparty “in good faith and without
    reason to know” of the non-party’s misrepresentation or undue
    influence “gives value or relies materially on the transaction.”
    Id. §§ 164, 177(3).
    Six informed the Taxpayers that Bolton planned to sign the
    Partnership Extension based on E&Y’s advice and that it would
    be signed unless Bolton Capital heard from them. And E&Y
    advised each Taxpayer to sign his Individual Extension.
    Accordingly, if the Taxpayers’ assent to any extension was due
    to E&Y’s misrepresentation or undue influence, the extension
    could be voidable. Importantly, however, for the Taxpayers to
    19
    void the extensions under either contract theory, they must
    have justifiably relied on E&Y. Id. §§ 164(2), 177(1).
    i. Esrey and LeMay
    In its Partnership Extension analysis, the Tax Court stated
    that the “problem” with the Taxpayers’ contract argument was
    that E&Y was not their “only adviser and they all had ample
    reason to question E&Y long before 2004” when the
    Partnership Extension was signed. BCP, 
    2017 WL 3394123
    , at
    *15. In other words, the Taxpayers were less likely to be
    unduly influenced because they had other advisors. And, in any
    case, they could not justifiably rely on E&Y because, by the
    time the Partnership Extension was signed, they should have
    questioned E&Y’s good faith—whether or not they knew of
    E&Y’s specific conflicts.
    To support its ruling that the January 2004 Partnership
    Extension was valid as to Esrey and LeMay, the Tax Court
    relied on several facts. In 2000, Esrey and LeMay hired the
    King & Spalding law firm to evaluate the Add-On. The law
    firm ultimately “questioned whether [the Add-On] could get
    through an audit.” 
    Id.
     In 2002, LeMay informed E&Y that he
    and Esrey had hired King & Spalding for its independent views
    and instructed E&Y to consult with the firm on “all strategic
    matters.” J.A. 538–39. In 2003, LeMay learned from a
    newspaper reporter that the IRS was investigating E&Y as a
    tax shelter promoter. The Tax Court found it “more likely than
    not,” given their relationship, that LeMay informed Esrey
    about the reporter’s information. BCP, 
    2017 WL 3394123
    , at
    *15. And in May 2004, Esrey and LeMay hired outside counsel
    to represent them in dealing with the IRS.
    The Tax Court concluded that Esrey’s and LeMay’s
    contract argument as to their Individual Extensions “doesn’t
    work for the same reason it didn’t work for the partnership-
    20
    level extension.” 
    Id.
     Accordingly, the Tax Court relied on the
    same facts to support its holding that Esrey’s and LeMay’s
    Individual Extensions—signed in December 2003 and January
    2004, respectively—were valid agreements under contract law.
    The Tax Court added that both Esrey and LeMay knew that
    E&Y was being investigated because E&Y told them and both
    Esrey and LeMay were “sophisticated businessmen.” 
    Id.
    We agree with the Tax Court. As early as 2000, King &
    Spalding put Esrey and LeMay on notice that something could
    be amiss with E&Y’s tax strategies. The Tax Court found that
    King & Spalding had “questioned” whether the Add-On would
    survive an audit. 
    Id.
     Esrey testified that King & Spalding told
    them both “the IRS had the better part of the argument”
    regarding E&Y’s tax strategies’ legitimacy. J.A. 1607–08.
    Even before hiring King & Spalding, LeMay was “beginning
    to get a little insecure about [his] lack of knowledge” regarding
    E&Y’s tax strategies after he read a news article discussing IRS
    challenges to Son-of-BOSS tax shelters; he and Esrey then
    decided to consult King & Spalding for advice. J.A. 858–59.
    Knowledge of the civil promoter audit was another reason
    Esrey and LeMay should have questioned E&Y’s actions. In
    2003 LeMay was contacted by a national newspaper and asked
    whether the promoter audit affected him. LeMay contacted
    E&Y and E&Y told him the settlement was unrelated to him.
    LeMay also read the press release regarding E&Y’s settlement
    of the promoter audit. The Tax Court’s inference that LeMay
    likely told Esrey about the call is reasonable, considering Esrey
    admitted he and LeMay “talk[ed] . . . frequently and share[d]
    each other’s thoughts or opinions” regarding press reports on
    E&Y’s tax shelters. J.A. 855–56.
    That Esrey and LeMay were sophisticated businessmen is
    also relevant in evaluating whether either was justified in
    21
    relying on E&Y. See Restatement (Second) Contracts § 177
    ill. 1 (“experience[] in business” relevant to whether one is
    “justified in assuming” individual he “rel[ied] [on] in business
    matters” will not act in manner inconsistent with his welfare).
    Sophisticated businessmen who hire a global accounting firm
    to prepare their tax returns should not rely unquestioningly on
    that firm once they have direct knowledge of IRS scrutiny of
    the firm’s tax strategies.13
    ii. Kalkhoven and Pettit
    As with Esrey and LeMay, the Tax Court concluded that
    Kalkhoven and Pettit could not rely on misrepresentation or
    undue influence to nullify the Partnership Extension because
    E&Y was not their “only adviser and they all had ample reason
    to question E&Y long before 2004.” BCP, 
    2017 WL 3394123
    ,
    at *15. In May 2002 E&Y advised Kalkhoven and Pettit that
    E&Y was delivering requested documents to the IRS related to
    “certain transactions in which [they] were involved” and
    invited them to contact E&Y’s outside counsel with any
    questions. 
    Id.
     Eventually, in September 2004, Kalkhoven and
    Pettit hired the Fulbright & Jaworski and Vinson & Elkins law
    13
    We do believe, however, that the Tax Court’s reliance on
    Esrey’s and LeMay’s hiring of outside counsel in May 2004 is
    misplaced. Counsel hired in May 2004 has no bearing on whether
    Esrey and LeMay justifiably relied on, or were unduly influenced by,
    E&Y when the relevant extensions had been signed. And we, like the
    Taxpayers, are unsure what the Tax Court meant when it noted that
    E&Y told Esrey and LeMay that prosecutors were investigating it
    because there does not appear to be record evidence to support that
    notation—at least no record evidence to support that disclosure
    having been made before the relevant extensions were signed.
    Regardless, the evidence the Tax Court utilized to support its
    timeliness holding predates Esrey’s and LeMay’s execution of their
    Individual Extensions and their approval of the Partnership
    Extension.
    22
    firms to represent them in dealing with the IRS. And while
    these firms represented Kalkhoven and Pettit, Bolton continued
    to sign Partnership Extensions through April 2007.
    Regarding Kalkhoven’s and Pettit’s Individual
    Extensions—signed in September 200414—the Tax Court
    similarly pointed to the fact that the two executives were then
    represented by Fulbright & Jaworski and Vinson & Elkins. And
    when they signed the extensions, both knew of E&Y’s conflicts
    because E&Y had already sent the Add-On clients to Fulbright
    & Jaworski because of those conflicts. E&Y also told
    Kalkhoven and Pettit in August 2002 that it was subject to a
    promoter audit regarding CDS and to contact its law firm of
    McKee Nelson with any questions.
    The Tax Court’s findings here were not error. Granted, the
    fact that Kalkhoven and Pettit were represented by Fulbright &
    Jaworski and Vinson & Elkins by September 2004 says nothing
    about their reliance on, or the undue influence wielded by,
    E&Y with respect to the January 2004 Partnership Extension.
    But that Fulbright & Jaworski represented them does inform
    whether they justifiably relied on E&Y in executing their
    September 2004 Individual Extensions. Kalkhoven and Pettit
    signed letters of engagement with Fulbright & Jaworski on the
    same day they signed their individual extensions. But E&Y had
    recommended that their clients transition to Fulbright &
    Jaworski in August 2004 due to the conflict of interest
    stemming from the May 2004 grand jury investigation. The
    Tax Court inferred that Kalkhoven and Pettit had received the
    letter because they hired the firm E&Y suggested in the letter.
    Before hiring Fulbright & Jaworski, Pettit had signed an
    14
    Because the three-year limitations period had not expired
    when Kalkhoven and Pettit signed their second Individual Extension
    for tax year 2000 in September 2004, the Tax Court used the
    September 2004 extensions as the operative ones.
    23
    engagement letter with Vinson & Elkins in March 2004, well
    before his September 2004 Individual Extension.
    Moreover, E&Y’s May 2002 letter also supports the Tax
    Court’s determination that Kalkhoven and Pettit should have
    questioned E&Y’s good faith. The letter informed them that the
    IRS had served E&Y with an administrative summons
    “demand[ing] the production of broad categories of documents
    and other information with regard to certain transactions in
    which [Kalkhoven and Pettit] were involved” and that E&Y
    intended to comply. J.A. 544–45. Another letter—in August
    2002—noted that the IRS was again examining E&Y
    transactions via an administrative summons. Importantly, it
    noted that the request related to the CDS transactions. Granted,
    CDS was different from the Add-On but they were related
    transactions in that Add-On was designed to eliminate capital
    gains taxes generated from the CDS transactions.
    In November 2003, before the Partnership Extension or
    Kalkhoven’s and Pettit’s September 2004 individual
    extensions were signed, Kalkhoven and Pettit received consent
    and disclosure forms from E&Y. The consent form stated that
    E&Y believed it could continue to represent Kalkhoven and
    Pettit effectively. But it also stated the IRS had “taken the
    position that E&Y acted as a tax shelter promoter of CDS and
    [the Add-On] transactions” and noted several potential sources
    of conflicts, including that E&Y had settled the promoter audit
    and that individual E&Y personnel might be subject to
    sanctions and might seek to assert defenses inconsistent with
    their clients’ interests. J.A. 885–88. The disclosure letter
    encouraged Kalkhoven and Pettit “to retain . . . independent
    counsel to work with [E&Y].” J.A. 713; J.A. 719. And it
    advised them that it was “rais[ing] . . . certain matters that
    could be deemed to constitute conflicts of interest under
    applicable ethical rules.” J.A. 714; J.A. 720. Nonetheless
    24
    Kalkhoven and Pettit signed conflict waivers in November
    2003—before the January 2004 Partnership Extension and
    their September 2004 Individual Extensions were executed.
    In sum, the Tax Court outlined various events that
    occurred before the Taxpayers’ Individual Extensions or the
    Partnership Extension were signed, all of which should have
    put the Taxpayers on notice that they should not rely on E&Y’s
    advice any longer. Accordingly, we see no clear error in the
    Tax Court’s findings.
    B. The “Sham” Determination
    In general, a partnership “may be disregarded where it is a
    sham or unreal.” Moline Props., Inc. v. Comm’r, 
    319 U.S. 436
    ,
    439 (1943); see also ASA Investerings, 
    201 F.3d at 512
    . And in
    a “sham” inquiry, “whether the ‘sham’ be in the entity or the
    transaction[,] . . . the absence of a nontax business purpose is
    fatal.” ASA Investerings, 
    201 F.3d at 512
    ; see also Horn v.
    Comm’r, 
    968 F.2d 1229
    , 1237 (D.C. Cir. 1992) (“extract[ing]”
    from economic substance and business purpose tests that
    transaction “will not be considered a sham if it is undertaken
    for profit or for other legitimate nontax business purposes”).
    Under the business purpose doctrine, “the Commissioner may
    look beyond the form of an action to discover its substance[;]”
    accordingly, although a “taxpayer may structure a transaction
    so that it satisfies the formal requirements of the Internal
    Revenue Code, the Commissioner may deny legal effect to a
    transaction if its sole purpose is to evade taxation.” ASA
    Investerings, 
    201 F.3d at 513
     (quoting Zmuda v. Comm’r, 
    731 F.2d 1417
    , 1420–21 (9th Cir. 1984)). Further, a partnership is
    not recognized as such for tax purposes unless “the parties
    25
    intended to join together as partners to conduct business
    activity for a purpose other than tax avoidance.” 
    Id.
    The Taxpayers15 argue that the Tax Court’s determination
    that BCP was a “sham” partnership was flawed because it
    applied the incorrect legal standard and misunderstood the facts
    as they related to the correct standard. Because the Tax Court
    applied the correct legal standard and because, viewing the
    record as a whole, we come to no “definite and firm conviction
    that a mistake has been committed” in its findings, U.S.
    Gypsum Co., 
    333 U.S. at 395
    , we affirm its sham
    determination.
    1.   Application of Luna
    The Taxpayers first argue that the Tax Court erred in using
    the factors set out in Luna v. Commissioner, 
    42 T.C. 1067
    (1964), to evaluate BCP because Luna is “analytically distinct”
    from the business purpose doctrine and focuses on the incorrect
    inquiry. Luna “distilled the principles” articulated in the United
    States Supreme Court’s decisions in Commissioner v. Tower,
    
    327 U.S. 280
     (1946), and Commissioner v. Culbertson, 
    337 U.S. 733
     (1949). WB Acquisition, Inc. v. Comm’r, 
    101 T.C.M. (CCH) 1157
    , 
    2011 WL 477697
    , at *9 (2011), aff’d, 
    803 F.3d 1014
     (9th Cir. 2015). In both Tower and Culbertson, the
    Supreme Court evaluated whether an existing partnership “is
    real within the meaning of the federal revenue laws.” Tower,
    
    327 U.S. at 290
    ; see also Culbertson, 
    337 U.S. at 741
    . Tower
    established that the key analysis is intent: “whether the partners
    really and truly intended to join together for the purpose of
    carrying on business and sharing in the profits or loses or both.”
    15
    In Tax Court only Kalkhoven and Pettit argued BCP was a
    legitimate partnership engaged in legitimate business. Esrey and
    LeMay conceded that the Add-On transactions were “bogus,” J.A.
    1619, and “outright frauds,” J.A. 1762.
    26
    
    327 U.S. at 287
    . Culbertson explained that the intent inquiry is
    fact-intensive and describes factors to evaluate an intent to
    form a partnership. 
    337 U.S. at 742
    .
    In Luna, the Tax Court considered whether the parties in a
    business relationship had informally entered into a partnership
    under the Tax Code, allowing them to claim that a payment to
    one party was intended to buy a partnership interest. See 
    42 T.C. at
    1076–77. To determine whether the parties formed an
    informal partnership for tax purposes, the Luna Court asked
    “whether the parties intended to, and did in fact, join together
    for the present conduct of an undertaking or enterprise.” 
    Id.
     at
    1077 (citing Culbertson, 
    337 U.S. at 733
    ). Luna listed non-
    exclusive factors to determine whether the intent necessary to
    establish a partnership existed. 
    Id.
     at 1077–78.16
    The Taxpayers are correct that Luna’s intent inquiry is
    “analytically distinct” from the business-purpose doctrine but
    the two analyses are not mutually exclusive. See, e.g.,
    Chemtech Royalty Assocs., LP v. United States, 
    766 F.3d 453
    ,
    460–61 (5th Cir. 2014) (Tower/Culberson inquiry appropriate
    16
    The Luna factors include: “The agreement of the parties and
    their conduct in executing its terms; the contributions, if any, which
    each party has made to the venture; the parties’ control over income
    and capital and the right of each to make withdrawals; whether each
    party was a principal and coproprietor, sharing a mutual proprietary
    interest in the net profits and having an obligation to share losses, or
    whether one party was the agent or employee of the other, receiving
    for his services contingent compensation in the form of a percentage
    of income; whether business was conducted in the joint names of the
    parties; whether the parties filed Federal partnership returns or
    otherwise represented to respondent or to persons with whom they
    dealt that they were joint venturers; whether separate books of
    account were maintained for the venture; and whether the parties
    exercised mutual control over and assumed mutual responsibilities
    for the enterprise.”
    27
    because “[t]he fact that a partnership’s underlying business
    activities had economic substance does not, standing alone,
    immunize the partnership from judicial scrutiny [under
    Culbertson]” (internal quotations omitted)); Historic
    Boardwalk Hall, LLC v. Comm’r, 
    694 F.3d 425
    , 461 (3d Cir.
    2012) (same); TIFD III-E, Inc. v. United States, 
    459 F.3d 220
    ,
    230–32 (2d Cir. 2006) (district court erred in considering only
    partnership’s “economic substance” and ignoring Culbertson’s
    “all-facts-and-circumstances test”). At least inferentially, we
    have recognized the Luna factors by describing the “basic
    inquiry” as “whether, all facts considered, the parties intended
    to join together as partners to conduct business activity for a
    purpose other than tax avoidance.” ASA Investerings, 
    201 F.3d at 513
    ; see also Andantech LLC v. Comm’r, 
    331 F.3d 972
    , 978
    (D.C. Cir. 2003) (citing Culbertson, 
    337 U.S. at
    742–43).
    Accordingly, the Luna factors are appropriately applied to the
    intent inquiry. See TIFD III-E, 
    459 F.3d at
    230–32 (Luna noted
    as one of multiple cases “identifying factors a court might
    consider” to evaluate whether partners joined partnership with
    requisite intent).
    The Taxpayers argue that, if Luna is applicable, BCP
    satisfies its factors. But the Tax Court disagreed and did not
    clearly err in this “fact-intensive inquiry.” Saba P’ship v.
    Comm’r, 
    273 F.3d 1135
    , 1140 (D.C. Cir. 2001). We agree with
    the Tax Court that “the agreement of the parties and their
    conduct in executing its terms” and “whether business was
    conducted in the joint names of the parties” weigh against
    finding BCP a partnership for tax purposes. BCP, 
    2017 WL 3394123
    , at *17 (quoting Luna, 
    42 T.C. at 1077
    ). BCP’s
    “business” was limited to one type of transaction: the Add-On.
    After accepting the options, BCP’s only activities were settling
    paired options and paying distributions, plus paying minimal
    advisor fees. And the fees paid to E&Y and Bolton to
    28
    participate in the Add-On were based on the tax loss generated
    by the Add-On.
    “[W]hether the parties exercised mutual control over and
    assumed mutual responsibilities for the enterprise” also weighs
    against finding BCP to be a bona fide partnership. 
    Id.
     (quoting
    Luna, 
    42 T.C. at 1078
    ). Bolton Capital had an unusual amount
    of control over BCP. The operating agreement gave Bolton
    Capital “all powers and rights necessary, proper, convenient or
    advisable to effectuate and carry out the purposes, business and
    objectives of the Company.” J.A. 269. The client members
    were not permitted “to take part in the management or control
    of the business or affairs of the Company, including, without
    limitation, voting to remove the Managing Member” or “have
    any voice in the management or operation of any Company
    property.” J.A. 274. Further, Bolton Capital was either the
    “Managing Member, General Partner, . . . Tax Matters
    Partner . . . [or had] Power of Attorney” for every client
    member and Bolton signed the BCP operating agreement on
    behalf of every client member. J.A. 82. The Taxpayers note that
    limited partnerships controlled by one general partner are
    commonplace. But Luna’s multi-factor test emphasizes that the
    determination is fact intensive—the Tax Court validly found
    that Bolton’s level of control was particularly unusual here.
    Accordingly, the Tax Court correctly applied the Luna
    factors to determine “whether the parties intended to, and did
    in fact, join together for the present conduct of an undertaking
    or enterprise” and correctly concluded that BCP failed the Luna
    analysis. BCP, 
    2017 WL 3394123
    , at *17.
    2.   The Business Purpose/Economic Substance Doctrines
    Generally, an entity is considered a “sham” and
    disregarded for tax purposes if it is not “undertaken for profit
    or for other legitimate nontax business purposes.” Horn, 968
    29
    F.2d at 1238 (applying economic substance and business
    purpose factors). Both the business purpose and economic
    substance doctrines “look beyond the form of an action to
    discover its substance.” ASA Investerings, 
    201 F.3d at 513
    (internal quotations omitted). Taxpayers are entitled to
    structure their business transactions “in such a way as to
    minimize tax” but the business purpose doctrine is not met if
    “such structuring is deemed to have gotten out of hand, to have
    been carried to such extreme lengths that the business purpose
    is no more than a facade.” 
    Id.
     The Taxpayers contend that
    BCP’s formation was intended to achieve, and in fact did
    achieve, diversification—an “indisputably legitimate business
    purpose.” Appellants’ Br. at 67.
    The Tax Court’s determination that diversification was
    merely a “facade” is well supported by the record. BCP, 
    2017 WL 3394123
    , at *19. Granted, the record contains conflicting
    evidence. Some testimony suggests diversification was a goal
    of BCP—for example, Bolton stated he believed pooling of the
    partners’ assets in BCP would provide diversification and E&Y
    told Kalkhoven the pooling of foreign currency investments in
    BCP would achieve diversification. But other testimony
    suggests any non-tax motive was fabricated. Six stated that she
    was not aware of any non-tax reason for contributing the option
    pairs to BCP and Bolton “helped fabricate a non-tax motivation
    used to falsely explain why clients participated in the CDS
    Add-On shelter.” J.A. 596. The Tax Court’s rejection of
    Kalkhoven’s and Pettit’s testimony on diversification as “not
    credible and inconsistent with the objective facts” is also well
    supported by the record. BCP, 
    2017 WL 3394123
    , *19 n.22.
    Both Kalkhoven and Pettit admitted they did not know what
    the Add-On was and did not even know their investments were
    part of the Add-On—they simply testified that, as part of a
    30
    broad investment plan, they invested with Bolton Capital to
    diversify.
    Although a finance/economics professor gave expert
    testimony that pooling of the option pairs achieved
    diversification, the Tax Court must “look beyond the form of
    [the] action to discover its substance.” ASA Investerings, 
    201 F.3d at 513
     (internal quotations omitted). Accordingly, it
    evaluated the substance of BCP and Add-On to determine the
    business purpose’s validity. It evaluated how the option pairs
    functioned and found the option pairs would never hit the sweet
    spot. The Tax Court found Add-On was focused on tax savings:
    it was promoted specifically to offset capital gains from CDS
    and transaction fees were based on the tax loss generated.
    Without the sweet spot, the maximum payout from
    participating in the Add-On was less than the transaction costs
    to acquire the options and participate.17 We agree with the Tax
    Court’s ultimate conclusion that BCP had no valid business
    purpose.
    Tax minimization as a primary consideration is not
    unlawful. ASA Investerings, 
    201 F.3d at 513
    . Nevertheless, the
    business purpose doctrine can be violated if the structuring for
    tax benefits has “gotten out of hand” and the business purpose
    is “no more than a facade.” Id.; see also 
    id. at 514
     (“a
    transaction will be disregarded if it did ‘not appreciably affect
    [taxpayer’s] beneficial interest except to reduce his tax.’”
    (brackets in original) (quoting Knetsch v. United States, 364
    17
    The Taxpayers’ argument that the Tax Court erred by
    considering the lack of profit motive misses the point—a transaction
    is valid under the business purpose doctrine if it is “undertaken for
    profit or for other legitimate nontax business purposes.” Horn, 
    968 F.2d at 1238
    . The Tax Court concluded that neither existed and,
    accordingly, found BCP to be a sham. We cannot fault the Tax Court
    for covering its bases.
    
    31 U.S. 361
    , 366 (1960)). In other words, the business purpose
    doctrine is “simply [a] more precise factor[] to consider in the
    application of this court’s traditional sham analysis; that is,
    whether the transaction had any practical economic effects
    other than the creation of income tax losses.” Horn, 
    968 F.2d at 1237
     (internal quotations omitted). We do not disagree with
    the Tax Court’s conclusion that BCP and the Add-On had no
    practical economic effect other than the creation of tax losses.
    Client members invested only $16.5 million in the option pairs
    and claimed $3.1 billion in tax losses. Those losses were
    artificial—which the Tax Court recognized. BCP, 
    2017 WL 3394123
    , at *16. And any diversification benefit was only in
    the options’ payoff distribution. But no option pair in fact paid
    out—they all either expired worthless or were sold before their
    exercise date. No “diversification benefit” in the payoff was
    had—plainly by design.18
    III. SIMPSON’S INTERVENTION
    Simpson’s motion for intervention came about through a
    gap in Tax Court rules. After the Tax Court released its 2017
    memorandum opinion, it ordered the parties to agree on the
    language of its final decisions. When the parties subsequently
    conferred, a non-participating party (Simpson) was discovered.
    If a tax case settles, Tax Court Rule 248 requires the
    Commissioner to move for entry of decision and the court to
    wait 60 days to see if a non-participating party objects to the
    settlement before issuing its decision. See Tax Ct. R. 248(b)(4).
    18
    To the extent the Tax Court’s statements regarding the effect
    of disregarding BCP could be read to determine the Taxpayers’
    outside bases in BCP, the Tax Court lacked jurisdiction to do so—
    which it acknowledged. BCP, 
    2017 WL 3394123
    , at *12; see
    Petaluma FX Partners, LLC v. Comm’r, 
    792 F.3d 72
    , 77 (D.C. Cir.
    2015). In addition, those findings were not included in the Tax
    Court’s final decisions.
    32
    There is no analogous rule, however, if the parties litigate and
    subsequently agree on the language of the decision. Here,
    Simpson’s late husband was a partner in Moore Trading
    Partners (MTP) and MTP was a partner in BCP; his estate “was
    an indirect partner and thus a party, [who] had not participated
    in the litigation.” J.A. 2448. In any event, on October 26, 2017,
    the Tax Court gave 60 days’ notice of the proposed decisions
    to non-participating parties. On August 6, 2018, Simpson,
    individually and as the surviving spouse of Singleton “Garry”
    Simpson, moved to intervene to assert an untimeliness defense.
    Simpson “adopt[ed] and incorporate[d]” the Taxpayers’ legal
    arguments regarding their statute of limitations defenses and
    attached documents to establish that she and her husband had
    not agreed to an individual extension until after the limitations
    period had expired. J.A. 2454. On February 6, 2019, the Tax
    Court denied Simpson’s motion to intervene.
    The Tax Court has not issued rules for third-party
    intervention. McHenry v. Comm’r, 
    677 F.3d 214
    , 216 (4th Cir.
    2012). Under Tax Court Rule 1(b), the Tax Court is authorized
    to prescribe such procedure, “giving particular weight to the
    Federal Rules of Civil Procedure to the extent that they are
    suitably adaptable to govern the matter at hand.” Tax Ct. R.
    1(b). We agree with the Fourth Circuit that, because Tax Court
    Rule 1(b) gives the Tax Court “broad discretion in deciding
    whether and to what extent to follow Federal Rule of Civil
    Procedure [(FRCP)] 24 governing intervention” and because
    “Rule 24 itself confers broad discretion on a trial court, we give
    great deference to a Tax Court’s decision to deny intervention,
    reviewing only for a clear abuse of discretion.” McHenry, 667
    F.3d at 216. Here, the Tax Court did not clearly abuse its
    discretion in denying Simpson’s motion to intervene.
    Simpson did not specify whether she was seeking
    mandatory intervention under FRCP 24(a) or permissive
    33
    intervention under FRCP 24(b) and so the Tax Court addressed
    both. First, the Tax Court noted intervention of right is not
    appropriate if the existing parties adequately represent the
    intervenor’s interests, see Fed. R. Civ. P. 24(a), and permissive
    intervention is not appropriate if it would unduly delay the
    adjudication of the existing parties’ rights, see Fed. R. Civ. P.
    24(b). It observed that, if either her individual extensions or the
    Partnership Extension was valid, any adjustments were timely.
    The Tax Court had earlier found the Partnership Extension
    valid and Simpson offered no additional argument on the
    Partnership Extension—incorporating by reference the
    Taxpayers’ failed argument. Accordingly, the Tax Court
    determined Simpson was adequately represented on the issue
    because she asserted no other basis for the Partnership
    Extension’s invalidity—failing intervention of right. It also
    concluded that Simpson failed permissive intervention because
    such intervention would “merely duplicate” the Taxpayers’
    Partnership Extension argument “which would serve only to
    further delay [the litigation’s] conclusion.” J.A. 2487. We
    therefore conclude that the Tax Court did not abuse its
    discretion in denying Simpson’s motion to intervene.
    For the foregoing reasons, the Tax Court’s memorandum
    opinion issued August 7, 2017, its order issued February 6,
    2019 and its two decisions issued February 7, 2019 are
    affirmed.
    So ordered.
