    SUMMARY*
    Tax
    The panel affirmed three Tax Court decisions involving
    federal income tax deficiencies and accuracy-related
    penalties.
    Greg Watkins and Daren Barone, owners of asbestos
    removal business Watkins Contracting, Inc. (WCI), structured
    WCI’s sale and reacquisition via various holding corporations
    to limit their personal exposure. WCI and one of the holding
    corporations, WB Partners, then formed the NTC Joint
    Venture for an environmental remediation project.
    The panel held that the Tax Court did not clearly err in
    finding no intent to operate the NTC Joint Venture as a bona
    fide partnership, and in taxing profits from the venture as
    income only to WCI.
    As part of the sale of WCI assets to Kuranda Capital, LP,
    Watkins, Barone, and WCI agreed not to compete with
    Kuranda in the environmental remediation business. The
    panel held that Watkins’s and Barone’s non-competition
    agreement with Kuranda may not be imputed to WB Partners,
    and that the Tax Court did not clearly err in not assigning any
    portion of the proceeds of the noncompetition agreement to
    WB Partners.

    Finally, the panel held that the Tax Court did not commit
    reversible error in assessing an accuracy-related penalty,
    because taxpayers identified no substantial authority or
    reasonable cause for their positions.

    OPINION
    MURGUIA, Circuit Judge:
    Daren Barone and Gregory Watkins drew upon their
    experience in asbestos removal to establish a successful
    environmental remediation company, Watkins Contracting,
    Inc (“WCI”). With success came risk—in particular, the
    danger that Barone and Watkins would be held personally
    liable for the cost of completing any projects that WCI was
    unable to finish. To shield themselves from this risk, the two
    men restructured WCI so that several corporate entities stood
    between them and the company. Barone and Watkins each
    formed a holding corporation, and the two corporations
    DJB HOLDING CORP. V. CIR                      5
    entered a partnership, Appellant WB Partners. Barone and
    Watkins also formed a third holding company, Appellant WB
    Acquisition, Inc., and transferred their interest in WCI to this
    company. Finally, WB Partners purchased all shares of WB
    Acquisition. As a result, WCI was owned by WB
    Acquisition, which was owned by WB Partners, which in turn
    was owned by Barone’s and Watkins’s holding corporations.
    This elaborate corporate structure provided Barone and
    Watkins with multiple levels of protection from personal
    liability. See Appendix.
    An opportunity arose to do environmental remediation
    work for a massive redevelopment project at the San Diego
    Naval Training Center (“NTC”). To win the contract,
    however, WCI would have to post a large bond against the
    possibility that it would be unable to complete the work. To
    ensure that WCI could afford the bond, Barone and Watkins
    caused WCI and WB Partners to form a joint venture, dubbed
    the NTC Joint Venture. Under the terms of the joint venture
    agreement, WCI would do the environmental remediation
    work, and WB Partners would supply financial guaranties. In
    exchange for these services, WCI would receive thirty
    percent of the venture’s profits, and WB Partners would
    receive seventy percent.
    The joint venture’s structure had significant federal
    income tax consequences. WCI would have to pay corporate
    income tax on its thirty-percent share of the venture’s profits.
    As a general partnership, WB Partners would pay no income
    tax on its seventy-percent share; instead, that income would
    pass through to WB Partners’ owners, the two holding
    corporations. The holding corporations were S corporations,
    whose income is treated in the same manner as that of a
    general partnership—it passes through to the S corporations’
    6               DJB HOLDING CORP. V. CIR
    shareholders. And because all shares of Barone’s and
    Watkins’s holding corporations were owned by tax-exempt
    retirement savings plans, WB Partners’ seventy-percent share
    of the NTC Joint Venture’s profits would only be subject to
    federal income tax if and when the retirement plans
    distributed benefits to their holders.
    While the NTC project was ongoing, WCI sold its assets
    to Kuranda Capital, LP (“Kuranda”). The purchase
    agreement allocated a portion of the sales price as
    consideration for a noncompetition agreement, whereby
    Watkins, Barone, and WCI agreed not to compete with
    Kuranda in the environmental remediation business. WB
    Partners claimed all of the proceeds of the noncompetition
    agreement on its tax returns.
    This action began when Appellants WB Partners, WB
    Acquisition, and Barone’s holding corporation (collectively,
    “Taxpayers”) challenged certain tax deficiencies identified by
    the Commissioner of Internal Revenue. In three consolidated
    decisions, the Tax Court found that the NTC Joint Venture
    was not a valid partnership for tax purposes, and therefore
    that all of the joint venture’s profits were taxable income to
    WCI. The Tax Court determined that all of the proceeds from
    the noncompetition agreement were income to WCI as well.
    Because WCI had substantially understated its income, the
    Tax Court upheld the Commissioner’s assessment of
    accuracy-related penalties. Taxpayers appealed.
    For the reasons that follow, we affirm the decisions of the
    Tax Court.
    DJB HOLDING CORP. V. CIR                   7
    BACKGROUND
    I. History of Watkins Contracting, Inc.
    In the early 1980s, Barone and Watkins worked in the
    asbestos removal business in Hawaii. Watkins later returned
    home to San Diego, where he went to work for his father’s
    asbestos removal company. The company soon expanded
    into other areas of environmental remediation. When Barone
    joined the company in the early 1990s, he and Watkins
    purchased it themselves, renaming it Watkins Contracting,
    Inc. (“WCI”).
    Barone was uncomfortable with the degree of personal
    liability involved in the environmental remediation business.
    In 1997, Barone and Watkins sold WCI’s stock to REXX
    Environmental Corp. (“REXX”), another environmental
    remediation company, thereby relieving themselves of any
    personal liability on future projects. REXX in turn hired
    Barone and Watkins to manage WCI. Barone became WCI’s
    CEO, and was responsible for “[t]he day-to-day business
    affairs, . . . anything from managing employees to handling
    financing to business development.” Watkins “oversaw a lot
    of the field.”
    REXX soon encountered financial difficulties, and
    approached Barone and Watkins to gauge their interest in
    repurchasing WCI. Barone and Watkins entered an
    agreement to buy WCI’s shares on June 10, 1999. The
    purchase closed on September 19, 2000.
    8                   DJB HOLDING CORP. V. CIR
    II. Birth of WB Partners
    Barone wanted to structure the purchase agreement to
    afford “(1) [p]ersonal protection from creditors; (2) layers of
    liability protection to operate WCI; (3) the ability to invest
    both together [with Watkins] and separately, depending on
    the risks involved in each project; (4) . . . qualified retirement
    plans; and (5) avoid[ance of] probate.” To accomplish these
    goals, Barone and Watkins stacked a number of holding
    companies between them and WCI to form a multi-layered
    liability shield.
    Barone and Watkins created WB Acquisition, Inc., and
    arranged for the company to receive WCI’s shares when the
    repurchase from REXX closed. They created two S
    corporations1—DJB Holding Corporation (“DJB”) and GSW
    Holding Corporation (“GSW”). Barone and Watkins then
    entered employment agreements with DJB and GSW,
    respectively, and each corporation adopted an employee stock
    ownership plan2 (“Plan”). The DJB Plan purchased all shares
    of DJB, and the GSW Plan purchased all shares of GSW.
    DJB and GSW then formed a general partnership called WB

    An “S corporation” is “a corporation that ha[s] elected to be taxed
    under Subchapter S of the [Internal Revenue] Code.” Gitlitz v. Comm’r,
    
    531 U.S. 206
    , 209 (2001). Like a general partnership, an S corporation
    does not pay income tax on its profits, but passes the profits through to its
    shareholders.

    An “employee stock ownership plan” is “a type of pension plan that
    invests primarily in the stock of the company that employs the plan
    participants.” Fifth Third Bancorp v. Dudenhoeffer, 
    134 S. Ct. 2459
    , 2463
    (2014). The earnings of such a retirement plan are exempt from income
    tax, and participants in the plan pay tax on their benefits only when the
    benefits are distributed.

    v. Chevron Corp., 
    203 F.3d 1099

    Partners, in which each corporation owned a fifty-percent
    interest. Finally, WB Partners acquired all shares of WB
    Acquisition. All the necessary documents were executed in
    September 2000.3
    According to Barone, the Plans were intended to provide
    qualified retirement plans, personal protection from creditors,
    and avoidance of probate. The holding corporations, DJB
    and GSW, permitted Barone and Watkins to pursue separate
    endeavors, while WB Partners allowed them to work together
    if they wished. Another consequence of the arrangement was
    that WB Partners’ income would escape taxation until the
    Plans distributed benefits: WB Partners, DJB, and GSW are
    all “pass-through” entities, 
    26 U.S.C. §§ 701
    , 1363(a),
    1366(a)–(c), and valid employee stock ownership plans are
    tax exempt, 
    26 U.S.C. §§ 401
    (a), 501(a), 4975(e)(7); T.D.
    9081, 
    68 Fed. Reg. 42970
    , 42970 (July 21, 2003).4
    As part of their employment agreements, Barone and
    Watkins agreed to render “construction management,
    indemnity, and financing services” exclusively for DJB and
    GSW, respectively. “Indemnity and financing services”
    include “providing personal guarantees required in order for
    clients of [DJB and GSW] to obtain a required performance
    bond.” In turn, DJB and GSW agreed on September 20,
    2000, to provide these services to WB Partners to the extent
    3
    The Commissioner concedes that “WB Partners, [GSW], and [DJB]
    exist for Federal income tax purposes.”
    4
    As a general partnership, WB Partners does not pay income tax on its
    profits, but passes its earnings on to its partners, DJB and GSW. See
    
    26 U.S.C. § 701
    . As noted, DJB and GSW are S corporations that pass
    their income on to their shareholders, the Plans, and the Plans are tax
    exempt. See supra nn.2, 3.
    10              DJB HOLDING CORP. V. CIR
    “necessary to manage and conduct the business of the
    Partnership.”
    The Tax Court found, and Taxpayers do not dispute, that
    Barone and Watkins performed the same roles for WCI after
    forming WB Partners as before. Watkins continued to
    oversee WCI’s work on a “day-to-day basis.” Barone
    continued to handle “business development” and “the
    financing.”
    In short, after the restructuring, WCI became a subsidiary
    of WB Acquisition, which was owned by WB Partners, which
    in turn was owned by the holding corporations DJB and
    GSW. Barone and Watkins became employees of their
    respective holding corporations rather than WCI, but
    continued to provide services to WCI according to the terms
    of their employment agreements. And WB Partners’
    structure ensured that Barone and Watkins would pay no tax
    on any of the partnership’s income until they began to receive
    benefits from their respective retirement plans.
    III.   The NTC Joint Venture
    In 1999 or 2000, the Corky McMillin Companies
    (“McMillin”), the Harper-Nielsen-Dillingham Joint Venture
    (“Harper”), and WCI joined forces to bid on a large
    redevelopment project at the San Diego Naval Training
    Center (“NTC”). The work would include removing various
    hazardous materials from nearly two hundred buildings. The
    City of San Diego awarded the contract to McMillin, who
    hired Harper as construction manager. WCI entered a
    subcontractor arrangement with Harper on December 1, 2000,
    for a lump-sum amount of $17,001,073. McMillin and
    Harper also required WCI to sign an indemnity agreement
    DJB HOLDING CORP. V. CIR                        11
    and post a full performance bond, as neither entity was
    willing to do so itself.
    Barone worried that assuming personal liability on a $17
    million bond could bankrupt him and WCI. In order to
    isolate the proceeds of the NTC project from WCI’s other
    work, Barone conceived the NTC Joint Venture.
    A. The Joint Venture’s Structure
    WCI and WB Partners executed the NTC Joint Venture
    Agreement on September 20, 2000, a week after WB Partners
    was formed and just over a month before WCI won the
    subcontract from Harper. Under the agreement, WCI would
    perform the actual remediation work and WB Partners would
    supply indemnity and financial guaranty services. The
    agreement further provided that WB Partners would receive
    seventy percent of the profits, and WCI would receive thirty
    percent.
    The tax consequences of this arrangement bear
    mentioning. Because the joint venture agreement entitled
    WCI only to thirty percent of the profits, WCI would have to
    pay income tax only on that portion.5 The remaining seventy
    percent of the profits would pass to WB Partners, whose
    income, as mentioned above, was not subject to taxation
    unless and until the Plans distributed benefits. In short, if the
    NTC Joint Venture were valid for tax purposes, only thirty
    percent of its income would be subject to tax now.
    5
    A joint venture is considered a “partnership” for tax purposes.
    
    26 U.S.C. § 761
    (a). Accordingly, the NTC Joint Venture would pay no
    tax on its income, but pass that income on to its members, WCI and WB
    Partners. See 
    26 U.S.C. § 701
    .
    12              DJB HOLDING CORP. V. CIR
    The agreement also provided that the joint venture would
    reimburse WCI for costs incurred in the remediation work,
    plus five percent. The agreement obligated the joint venture
    to keep books and records and to file income tax returns. It
    contemplated that Harper would award the subcontract to
    WCI, not to the joint venture, and make payments directly to
    WCI.
    B. The Joint Venture’s Conduct
    On September 20, 2000, the same day the NTC Joint
    Venture was created, WCI, WB Partners, Barone’s and
    Watkins’s holding corporations, and the NTC Joint Venture
    executed a general indemnity agreement with the American
    International Group of Companies (“AIG”). The same
    entities entered a second indemnity agreement with
    Greenwich Insurance Company on January 2, 2002. Pursuant
    to the agreements, the NTC Joint Venture and all the entities
    that constituted it agreed to indemnify AIG and Greenwich
    against any costs incurred in executing a bond.
    The Insurance Company of the State of Pennsylvania
    issued a performance bond on October 18, 2000, and replaced
    it soon after with a superseding bond. The bond named WCI
    as principal, the insurance company as surety, and both
    McMillin and Harper as obligees. The face amount was
    $17,001,073, the value of WCI’s lump-sum subcontract with
    Harper.
    The NTC Joint Venture obtained an employer
    identification number and its own bank account. The joint
    venture also tracked its own financing and prepared its own
    progress reports.      As the joint venture agreement
    contemplated, WCI received payment from Harper directly.
    DJB HOLDING CORP. V. CIR                        13
    Notwithstanding the terms of the agreement, the joint
    venture’s accountant opted not to file a tax return for the
    venture. Instead, the accountant believed that separately
    reporting WCI’s and WB Partners’ income from the NTC
    project was sufficient.
    As of September 30, 2002, WCI had billed Harper for
    $14,100,332, and incurred costs (plus five percent) of
    $5,822,738. This yielded a profit of $8,277,599, of which
    WB Partners was entitled to a seventy-percent share, or
    $5,794,319. In reality, a WCI invoice reflects that WCI paid
    WB Partners only $4,172,000, and kept for itself the
    remaining $1,622,319. As a result, WB Partners received
    only 50.4% of the profits, not 70%. Barone testified that the
    extra $1.6 million was a “bonus” to WCI in recognition of “a
    job well done.”
    IV.     Sale of WCI’s Assets to Kuranda Capital
    WCI entered an asset purchase agreement with Kuranda
    Capital, LP (“Kuranda”),6 on April 18, 2003. The parties
    agreed upon a purchase price for WCI’s assets of $4,923,091
    in cash and a $500,000 promissory note. As part of the
    transaction, Watkins, Barone, and WCI agreed not to compete
    with Kuranda in the environmental remediation business.
    The asset purchase agreement allocated $3.4 million of the
    purchase price to the noncompetition agreement. Taxpayers’
    accountant reported all of the noncompetition agreement’s
    proceeds, including interest from the note, on WB Partners’
    tax returns.
    6
    Kuranda later changed its name to Watkins Contracting, L.P., and
    finished the environmental remediation portion of the NTC project as
    WCI’s subcontractor.

    V. Tax Court
    The Commissioner notified WB Acquisition and WB
    Partners of tax deficiencies for the years 2002 through 2005.
    Taxpayers filed petitions for adjustment. The Tax Court held
    that (1) the NTC Joint Venture was not a valid partnership for
    tax purposes, (2) only WCI was bound by the noncompetition
    agreement, and the $3.4 million allocated to the agreement
    was income only to WCI, and (3) accuracy-related penalties
    applied.
    JURISDICTION
    This Court has jurisdiction over Taxpayers’ timely appeal
    under 
    26 U.S.C. § 7482
    .
    STANDARD OF REVIEW
    This Court reviews the Tax Court’s conclusions of law de
    novo and its findings of fact for clear error. Custom Chrome,
    Inc. v. Comm’r, 
    217 F.3d 1117
    , 1121 (9th Cir. 2000).
    Whether a valid partnership existed for tax purposes turns on
    whether the parties intended in good faith to act as partners.
    Comm’r v. Culbertson, 
    337 U.S. 733
    , 741–42 (1949).
    Whether there was such an intent is a question of fact.
    Comm’r v. Tower, 
    327 U.S. 280
    , 287 (1946). To which party
    to attribute an item of income is a mixed question of law and
    fact, reviewed de novo “unless the question is primarily
    factual.” Sparkman v. Comm’r, 
    509 F.3d 1149
    , 1157 (9th
    Cir. 2007).
    Where the Tax Court imposed an accuracy-related
    penalty, we review de novo whether substantial authority
    supported the taxpayer’s position. Little v. Comm’r, 106 F.3d
    DJB HOLDING CORP. V. CIR                     15
    1445, 1449 (9th Cir. 1997). Whether the taxpayer acted with
    reasonable cause and in good faith is a finding of fact
    reviewed for clear error. See Hansen v. Comm’r, 
    471 F.3d 1021
    , 1029–30 (9th Cir. 2006) (holding that the Tax Court
    did not clearly err in finding a lack of reasonable cause and
    good faith).
    Under the clear error standard, the Tax Court’s fact
    findings are upheld if its “account of the evidence is plausible
    in light of the record viewed in its entirety.” Wolf v. Comm’r,
    
    4 F.3d 709

    DISCUSSION
    I. Income from the NTC Project Attributed to WB
    Partners Was in Fact Income to WCI.
    Taxpayers raise two arguments in the alternative. First,
    they argue that the Tax Court clearly erred in finding that the
    NTC Joint Venture was not a valid partnership for tax
    purposes. Second, they argue that, even if the joint venture
    was not a valid partnership, WCI and WB Partners reached a
    bona fide agreement to compensate WB Partners for
    providing financial guaranties. We conclude that the Tax
    Court properly taxed WCI on all income from the NTC
    project.
    16              DJB HOLDING CORP. V. CIR
    A. The NTC Joint Venture Was Not a Valid
    Partnership for Tax Purposes.
    For tax purposes, a “partnership” is “a syndicate, group,
    pool, joint venture, or other unincorporated organization” that
    carries on “any business, financial operation, or venture” and
    that is not “a corporation or a trust or estate.” 
    26 U.S.C. §§ 761
    (a), 7701(a)(2). To determine whether a purported
    joint venture is a valid partnership, courts ascertain whether
    “the parties in good faith and acting with a business purpose
    intended to join together in the present conduct of the
    enterprise.” Culbertson, 
    337 U.S. at 742
    . The Tax Court
    distilled from Culbertson eight factors to consider in
    measuring the parties’ intent:
    [(1)] [t]he agreement of the parties and their
    conduct in executing its terms; [(2)] the
    contributions, if any, which each party has
    made to the venture; [(3)] the parties’ control
    over income and capital and the right of each
    to make withdrawals; [(4)] whether each party

    enterprise.
    Luna v. Comm’r, 
    42 T.C. 1067
    , 1077–78 (1964).
    Here, the Tax Court concluded that the Luna factors
    weighed against the conclusion that the NTC Joint Venture
    was a valid partnership. Regarding the first factor, the court
    noted that the parties violated the terms of the joint venture
    agreement both by imposing a 50.4% profit cap on WB
    Partners and by failing to file a tax return. These deviations
    from the agreement suggested to the Tax Court that WCI and
    WB Partners did not intend in good faith to act as partners.
    Second, the court found that WB Partners contributed nothing
    of value to the joint venture because the performance bond
    was issued based not on WB Partners’ financial guaranties,
    but on the collective net worth of WCI, WB Partners, Barone,
    Watkins, DJB, and GSW as related entities. The marginal
    value of WB Partners’ guaranty suggested that WB Partners
    did not make a meaningful contribution to the joint venture.
    Third, the venture’s imposition of a profit cap on WB
    Partners demonstrated that WB Partners exercised no control
    over income and capital, further suggesting that WB Partners
    did not act as a bona fide partner.
    Fourth, the profit cap and the joint venture agreement’s
    provision guaranteeing reimbursement of WCI’s costs
    showed that WCI and WB Partners did not intend to share
    profits and losses as bona fide partners would. Concerning
    the eighth factor, the court found that WB Partners’
    concession of a large portion of the profits to which it was
    entitled showed that the parties did not exercise mutual
    18                  DJB HOLDING CORP. V. CIR
    control over the enterprise. The court found the remaining
    factors neutral in light of the joint venture’s efforts to conduct
    itself as a valid partnership, such as opening a separate bank
    account and keeping its own records.7
    On appeal, Taxpayers take issue only with the Tax
    Court’s finding regarding the second Luna factor—that WB
    Partners contributed nothing of value to the NTC Joint
    Venture. They do not dispute the Tax Court’s application of
    the Luna factors in any other respect, except to assert that the
    court’s assessment of WB Partners’ contribution to the
    venture “infected” its analysis of the other factors.
    Before the Tax Court, Taxpayers argued that WB
    Partners’ financial guaranty was an essential contribution to
    the NTC Joint Venture because WCI could not have won the
    NTC project without it. The Tax Court disagreed. It
    specifically noted that WCI won the NTC bond based on “the
    combined net worth and financial guaranties of each of WCI,
    WB Partners, Barone, Watkins, DJB, and GSW,” not based
    on WB Partners’ guaranty alone. Moreover, the court
    reasoned that WB Partners would have supplied a guaranty
    even if the joint venture had never existed, by virtue of being
    the parent entity of WCI. Finally, the court noted that only
    7
    The Tax Court found the fifth factor “mixed” because the NTC Joint
    Venture obtained and used its own employer identification number as a
    legitimate entity would, but WCI dealt with Harper, the construction
    contractor, entirely in its own name. The sixth factor was neutral because,
    while the joint venture did not file its own tax return, it dealt with various
    banks as an entity separate from WCI and WB Partners. Finally, the Tax
    Court found the seventh factor neutral because the joint venture
    maintained its own bank account, income statements, and progress reports,
    but did so using WCI employees and did not keep “other books of account
    that may normally be expected in the operation of a business.”
    DJB HOLDING CORP. V. CIR                    19
    WB Partners received compensation for its financial
    guaranty, while Barone, Watkins, DJB, and GSW each
    guaranteed the bond without receiving a share of the NTC
    project’s profits. If WB Partners’ guaranty warranted
    compensation to the tune of seventy percent of the profits, the
    Tax Court reasoned, then surely the other entities’ guaranties
    also called for some share of the proceeds.
    On appeal, Taxpayers argue that WB Partners’ financial
    guaranty and those of its owners and their employees were in
    fact a valuable contribution because WCI could not otherwise
    have posted a performance bond. They contend that Tax
    Court case law supports this conclusion. In Maxwell v.
    Commissioner, 
    29 T.C.M. (CCH) 1356
     (1970), a bridge
    construction corporation and its majority owner formed a
    joint venture to bid on a lucrative contract. 
    Id. at 1358
    . The
    corporation supplied all the materials and labor, and the
    owner provided a personal financial guaranty to enable the
    corporation to post a bond. 
    Id.
     Because the corporation’s net
    worth was not alone sufficient to secure the bond, the Tax
    Court found that the owner’s guaranty was a valuable
    contribution showing intent to form a partnership. 
    Id. at 1362
    .
    As in Maxwell, Taxpayers argue, WCI could not have
    secured the necessary $17 million bond on its own. WB
    Partners’ guaranty, along with those of its partner holding
    corporations and their employees, made obtaining that bond
    possible. Because WB Partners’ financial guaranty, as well
    as those of Barone, Watkins, and their holding corporations,
    enabled WCI to obtain a performance bond, Taxpayers argue
    that the Tax Court clearly erred in finding that WB Partners
    contributed nothing valuable to the joint venture.
    20              DJB HOLDING CORP. V. CIR
    We conclude that the record supports the Tax Court’s
    finding that WB Partners contributed no value to the NTC
    Joint Venture. Had the joint venture never existed, WB
    Partners would still be obligated to offer Barone’s and
    Watkins’s guaranties because both men promised to provide
    financial services as necessary to support WB Partners’
    business. As WB Partners’ wholly owned subsidiary, WCI
    would have been entitled to Barone’s and Watkins’s
    guaranties even if WB Partners did not promise to provide
    those guaranties to the joint venture.
    In September of 2000, in their employment agreements
    with the holding corporations DJB and GSW, Barone and
    Watkins promised to provide guaranties to enable the
    corporations’ clients to post performance bonds. Later that
    month, DJB and GSW amended WB Partners’ general
    partnership agreement to offer Barone’s and Watkins’s
    services as “necessary to manage and conduct the business of
    [WB Partners].” The amendment offered Barone’s and
    Watkins’s services not only to WB Partners itself, but also to
    any “third parties in connection with” WB Partners’ business.
    WCI’s environmental remediation work for the NTC
    redevelopment project was part of WB Partners’ business
    because WB Partners wholly owned WB Acquisition, which
    in turn wholly owned WCI. Because WCI’s work on the
    NTC project was part of WB Partners’ business, the
    partnership agreement required Barone and Watkins to
    provide any financial guaranties necessary to permit WCI to
    obtain the bond it needed to perform the work. Accordingly,
    WB Partners was obligated to furnish Barone’s and Watkins’s
    guaranties independently of the joint venture agreement. WB
    Partners’ commitment to provide guaranties to the NTC Joint
    Venture therefore was superfluous.
    DJB HOLDING CORP. V. CIR                   21
    Not only did Barone’s and Watkins’s guaranties
    contribute no value to the joint venture independent of what
    they were already obligated to provide, but the record also
    belies any argument that WB Partners’ own guaranty, or
    those of DJB and GSW, held independent value. An
    employee of AIG, one of the companies that executed an
    indemnity agreement with the NTC Joint Venture, remarked
    that the performance bond issued because WCI, Barone, and
    Watkins were “financially sound indemnitors.”             The
    employee recalled that WCI’s financial condition was “very
    good” and that Barone and Watkins both had a “pretty high”
    net worth. He did not remember WB Partners’ financial
    condition (or that of DJB and GSW) at all. Moreover, at the
    time WB Partners provided its guaranty, it had no other assets
    outside its equity in the NTC Joint Venture and WB
    Acquisition. This evidence supports the Tax Court’s
    conclusion that WB Partners’ guaranty contributed no
    additional value to the NTC Joint Venture. Only Barone’s
    and Watkins’s guaranties enhanced WCI’s ability to secure a
    performance bond, and they were obligated to provide the
    guaranties purely by virtue of their employment agreements
    and the amended partnership agreement. Maxwell is
    therefore inapposite, as the majority shareholder in that case
    was not obligated to offer his personal guaranty by any
    contract outside of the partnership agreement. See 29 T.C.M.
    (CCH) at 1358.
    Because Barone and Watkins were contractually obligated
    to provide any guaranties necessary to permit WCI to perform
    environmental remediation work, WB Partners’ separate
    commitment to provide those guaranties to the joint venture
    was superfluous. The Tax Court therefore did not clearly err
    in concluding that WB Partners contributed nothing of value
    to the NTC Joint Venture. Because Taxpayers do not
    22              DJB HOLDING CORP. V. CIR
    challenge the Tax Court’s analysis of any of the other Luna
    factors, it necessarily follows that the Tax Court did not
    clearly err in finding that Taxpayers did not intend to operate
    the NTC Joint Venture as a bona fide partnership. See Luna,
    
    42 T.C. at 1077
    –79; Culbertson, 
    337 U.S. at 742
    .
    B. WCI and WB Partners Did Not Agree in Good
    Faith To Share Profits.
    Of course, if the NTC Joint Venture was not a valid
    partnership for tax purposes, then WB Partners does not have
    a partnership interest entitling it to declare as income a share
    of the profits from the NTC project. Taxpayers argue in the
    alternative that WCI agreed in good faith to assign WB
    Partners a share of the profits in exchange for WB Partners’
    signing the indemnity agreement.
    Where a taxpayer agreed to pay a portion of the profits
    from an enterprise in exchange for financial assistance from
    another, that portion of the profits is income to the entity
    providing the assistance, not to the taxpayer. See Stevens
    Bros. & Miller-Hutchinson Co., Inc. v. Comm’r, 
    24 T.C. 953
    ,
    956–57 (1955). In Stevens Brothers, the taxpayer, a
    corporation in the heavy construction business, was unable to
    bid on a public works project because it had insufficient
    capital to obtain a loan. 
    Id. at 954
    . Another corporation
    agreed to loan the taxpayer the necessary additional capital in
    exchange for a one-half share of the profits from the project.
    
    Id. at 955
    . In accordance with the agreement, the taxpayer
    declared only half of the profits as income. 
    Id. at 956
    . The
    Tax Court held that this was proper. 
    Id.
     The risk of loss to
    the second corporation was real, the terms of the agreement
    were fair, and the interests of both corporations were
    sufficiently “adverse” to permit the conclusion that the
    DJB HOLDING CORP. V. CIR                            23
    contract was “bona fide.” 
    Id.
     In addition, the corporations
    actually shared the profits at the agreed-upon fifty-percent
    division, further demonstrating that the agreement was
    genuine. 
    Id.
    Taxpayers argue that, as in Stevens Brothers, WCI and
    WB Partners agreed that WB Partners would receive a
    portion of the profits from the NTC project in exchange for
    providing necessary financial assistance to WCI—in this
    case, a financial guaranty. As in Stevens Brothers, WB
    Partners assumed substantial financial risk by agreeing to
    indemnify the surety on the performance bond. Also as in
    Stevens Brothers, Taxpayers assert, the parties to the joint
    venture agreed that WB Partners would receive a percentage
    share of the profits in exchange for its guaranty.
    To the contrary, Taxpayers’ conduct shows that WCI and
    WB Partners did not reach a bona fide agreement to transfer
    a share of the profits to WB Partners in exchange for its
    guaranty. According to the joint venture agreement, WB
    Partners was to receive seventy percent of the profits for this
    service. Instead, as reflected in an invoice, WCI unilaterally
    reduced WB Partners’ share to 50.4%. It is questionable that
    a company dealing with WCI at arms’ length would give up
    a nearly twenty-percent share of the profits—approximately
    $1.6 million—so casually. This disregard for the joint
    venture agreement’s terms demonstrates that WCI and WB
    Partners did not intend in good faith to be bound by that
    agreement.8 Accordingly, the Tax Court did not clearly err in
    8
    Taxpayers argue in the alternative that they are entitled to deduct WB
    Partners’ share “as an ordinary and necessary bond guaranty expense.” See
    A.A. & E.B. Jones Co. v. Comm’r, 
    19 T.C.M. (CCH) 1561
    , 1563 (1960)
    (permitting the taxpayer to deduct as a business expense a share of profits
    24                 DJB HOLDING CORP. V. CIR
    finding that WCI and WB Partners did not reach a bona fide
    agreement to share profits. Cf. Stevens Bros., 
    24 T.C. at 956
    (noting that the lending corporation received “payment of the
    agreed amounts”).
    The record supports the Tax Court’s finding that WB
    Partners contributed no value to the NTC Joint Venture, and
    therefore that WB Partners and WCI did not act as bona fide
    partners. See Luna, 
    42 T.C. at 1077
    –79; Culbertson, 
    337 U.S. at 742
    . WCI’s arbitrary reduction of WB Partners’ share of
    the proceeds further supports the Tax Court’s finding that the
    two entities did not reach a bona fide agreement to share
    profits. Cf. Stevens Bros., 
    24 T.C. at 956
    . Accordingly, the
    Tax Court properly determined that all of the profits from the
    NTC Joint Venture were income to WCI.
    II. Proceeds from the Noncompetition Agreement Were
    Income to WCI Rather Than WB Partners.
    The “first principle of income taxation” is “that income
    must be taxed to him who earns it.” Culbertson, 
    337 U.S. at
    739–40. When a commercial transaction includes a
    noncompetition agreement, the portion of the proceeds
    allocated to that agreement is income to the persons who
    promised not to compete. For example, when an agreement
    to sell a corporation’s assets includes promises by its
    shareholders that they will not compete with the purchaser,
    the shareholders must declare as income the consideration
    paid to shareholders who indemnified a bond surety). Because we affirm
    the Tax Court’s conclusion that the parties did not intend in good faith to
    transfer a share of the profits to WB Partners in exchange for its
    guaranties, we must also reject the suggestion that WCI is entitled to
    deduct that share as a business expense.
    DJB HOLDING CORP. V. CIR                    25
    they receive for their promises. See Beals’ Estate v. Comm’r,
    
    82 F.2d 268
    , 270 (2d Cir. 1936) (holding that stock
    transferred in exchange for a taxpayer’s agreement not to
    compete was income to the taxpayer, and not merely
    “ancillary” to a larger reorganization plan); Cox v. Helvering,
    
    71 F.2d 987
    , 988 (D.C. Cir. 1934) (holding that money paid
    in exchange for a shareholder’s agreement not to compete
    was income to the shareholder). By promising not to
    compete with the purchaser’s business, the shareholders
    “earn” the consideration that the purchaser offers in exchange
    for the promise. See Cox, 71 F.2d at 988 (“If [a person]
    refrains from exercising his skill and ability in a particular
    line for a definite period, what he receives in compensation
    . . . is income.”).
    Of the roughly $5.5 million price at which Kuranda
    agreed to purchase WCI’s assets, the Tax Court concluded
    that the $3.4 million portion allocated to the noncompetition
    agreement was income to WCI, not WB Partners. The
    noncompetition clause prohibits Barone, Watkins, and WCI
    from engaging in “Competing Services,” which are defined
    to include any
    (i) service that has been provided, performed
    or offered by or on behalf of WCI (or any
    predecessor of WCI) at any time on or prior to
    the date of this Noncompetition Agreement
    that involves or relates to asbestos, mold, and
    lead abatement in residential, commercial and
    government properties; (ii) service that is
    substantially the same as, is based upon or
    competes in any material respect with any
    service referred to in clause “(i)” of this
    sentence.
    26              DJB HOLDING CORP. V. CIR
    (alterations omitted). To summarize, Barone, Watkins, and
    WCI agreed not to compete with Kuranda in providing any
    service related to “asbestos, mold, and lead abatement.”
    The Tax Court noted that WCI was the only signatory to
    the noncompetition agreement ever to perform “asbestos,
    mold, and lead abatement” services. Moreover, it was the
    only entity bound by the agreement that “had the proper
    licenses and permits to perform the necessary construction
    and excavation work.” While Barone’s and Watkins’s
    services were necessary to WCI’s operations, the court found
    that WCI was entitled to those services because both men
    were WCI officers. As the only entity capable of competing
    with Kuranda in providing environmental remediation
    services, the court found, WCI was the only party truly bound
    by the agreement. The Tax Court therefore concluded that
    WCI earned all of the proceeds. Accordingly, it found that
    the interest on Kuranda’s $500,000 promissory note was also
    income to WCI, not WB Partners. Because the Tax Court’s
    analysis was “primarily factual,” we review its assignment of
    the proceeds of the noncompetition agreement to WCI for
    clear error. See Sparkman, 
    509 F.3d at 1155, 1157
    .
    As Taxpayers correctly observe, the Tax Court erred in
    finding that only WCI was bound by the noncompetition
    agreement. Instead, the agreement also bound Barone and
    Watkins personally. Contrary to the Tax Court’s reasoning,
    Barone’s and Watkins’s status as WCI officers does not
    entitle WCI to their services because Barone and Watkins
    were employees of their holding corporations, DJB and GSW,
    not of WCI. Further, even if they were employees of WCI,
    Barone and Watkins were free to terminate their relationship
    with WCI at any time. Because California is an at-will
    employment state, WCI was not entitled to Barone and
    DJB HOLDING CORP. V. CIR                  27
    Watkins’s services in the future absent a contractual
    agreement to that effect. See 
    Cal. Lab. Code § 2922
     (“An
    employment, having no specified term, may be terminated at
    the will of either party on notice to the other.”); Guz v.
    Bechtel Nat’l, Inc., 
    8 P.3d 1089
    , 1110 (Cal. 2000) (“The mere
    existence of an employment relationship affords no
    expectation, protectible by law, that employment will
    continue . . . unless the parties have actually adopted such
    terms.”). The record contains no evidence of such an
    agreement. Accordingly, under California law, Barone and
    Watkins were free to sever their ties to WCI and perform
    environmental remediation services for another company.
    The noncompetition agreement therefore bound Barone and
    Watkins personally not to compete with Kuranda in the
    environmental remediation business.
    Taxpayers go on to argue that the noncompetition
    agreement binds Barone and Watkins alone, not WCI, and
    that WB Partners, not Barone and Watkins, is entitled to the
    proceeds of the agreement. This argument rests on two
    fundamental misapprehensions. First, by its plain terms, the
    agreement forbids “[e]ach of Seller, Watkins and Barone”
    from performing competing services. The agreement goes on
    to provide that the $3.4 million amount be “allocated as
    partial consideration for Seller’s and the Shareholders’
    obligations” not to compete. The asset purchase agreement
    defines “Seller” as WCI, and “Shareholders” refers to Barone
    and Watkins. The terms of the noncompetition agreement
    demonstrate that Barone, Watkins, and WCI each earned a
    share of the $3.4 million proceeds.
    Second, the proceeds of the noncompetition agreement
    are not income to WB Partners because the partnership, like
    WCI, has no future claim to Barone’s and Watkins’s services.
    28                 DJB HOLDING CORP. V. CIR
    It is true that Barone and Watkins agreed to provide their
    services exclusively for their holding corporations, DJB and
    GSW. DJB and GSW, in turn, agreed to provide Barone’s
    and Watkins’s services to WB Partners. However, Barone’s
    and Watkins’s employment agreements with DJB and GSW
    provide that either party may terminate employment at any
    time with ninety days’ notice to the other. Accordingly,
    Barone and Watkins were free to leave DJB and GSW and go
    off to perform environmental services for another company.
    Because WB Partners had no right to expect Barone and
    Watkins to continue to provide their services into the future,
    Barone’s and Watkins’s agreement not to compete with
    Kuranda may not be imputed to WB Partners. WB Partners
    therefore earned no part of the consideration for the
    noncompetition agreement.
    WCI, Barone, and Watkins each are individually bound
    not to compete with Kuranda, and therefore are each entitled
    to a share of the noncompetition agreement. See Beals’
    Estate, 
    82 F.2d at 270
    ; Cox, 71 F.2d at 988. Because WB
    Partners has no claim to Barone’s and Watkins’s future
    services, WB Partners is entitled to no share at all. See
    Culbertson, 
    337 U.S. at
    739–40. Accordingly, the Tax Court
    did not clearly err in declining to assign any portion of the
    proceeds of the noncompetition agreement to WB Partners.9
    9
    Were the question before us, we may be inclined to hold that the Tax
    Court clearly erred in failing to assign any share of the noncompetition
    agreement’s proceeds to Barone and Watkins individually. Neither party
    has asked that we do so.
    DJB HOLDING CORP. V. CIR                     29
    III.      The Tax Court Properly Assessed Accuracy-
    Related Penalties.
    The Internal Revenue Code imposes a twenty-percent
    penalty on “[a]ny substantial understatement of income tax.”
    
    26 U.S.C. § 6662
    (b)(2), (a). Even in the event of a
    substantial understatement, however, the taxpayer may escape
    the penalty if one or both of two conditions applies. First, a
    taxpayer does not owe a penalty where the taxpayer can
    identify “substantial authority” supporting its treatment of an
    item of income. 
    26 U.S.C. § 6662
    (d)(2)(B)(i). Second, to the
    extent that the taxpayer had reasonable cause for its position
    and acted in good faith, the penalty does not apply. 
    26 U.S.C. § 6664
    (c)(1).
    The Tax Court assessed penalties against Taxpayers for
    substantially understating their income. Taxpayers argue that
    the Tax Court’s decisions in Maxwell and Stevens Brothers
    furnish substantial authority for their positions that the NTC
    Joint Venture was a valid partnership and that the parties to
    the venture agreed in good faith to share profits. They also
    contend that they relied reasonably and in good faith on the
    advice of their accountant in reaching those positions.
    Finally, they assert that their positions are reasonable in light
    of the complexity of the law governing the validity of
    partnerships for tax purposes. For the reasons discussed
    below, we reject Taxpayers’ arguments and affirm the district
    court’s imposition of accuracy-related penalties.
    A. Maxwell and Stevens Brothers Do Not Furnish
    Substantial Authority for Taxpayers’ Position.
    “The substantial authority standard” is somewhat less
    stringent than the “more likely than not standard.” Treas.
    30               DJB HOLDING CORP. V. CIR
    Reg. § 1.6662-4(d)(2). Substantial authority supports the
    taxpayer’s position if, taking into account all relevant
    authorities, “the weight of the authorities supporting” the
    taxpayer’s position is “substantial” when compared to the
    weight of authorities that are contrary to the taxpayer’s
    position. § 1.6662-4(d)(3)(i). The weight that a court should
    assign to an authority “depends on its relevance and
    persuasiveness, and the type of document providing the
    authority.” § 1.6662-4(d)(3)(ii). A Tax Court disposition may
    be relevant authority, but is “not particularly relevant” if it “is
    materially distinguishable on its facts.” Id.
    Taxpayers advance two Tax Court opinions as substantial
    authority for their position that the share of the profits from
    the NTC project transferred to WB Partners is properly WB
    Partners’ income. One is Maxwell, in which the court found
    that a corporation and its majority shareholder formed a valid
    partnership when the shareholder agreed to guarantee a
    necessary bond in exchange for a share of the profits. 29
    T.C.M. (CCH) at 1362. The second is Stevens Brothers, in
    which the court held that a corporation properly declared only
    half the profits from a project as income where it agreed to
    pay the other half to another corporation in exchange for a
    capital loan. 
    24 T.C. at 955
    –56.
    Maxwell and Stevens Brothers do not amount to
    substantial authority because they are materially
    distinguishable. In each case, the taxpayer reached a bona
    fide agreement to share the profits from an endeavor in
    exchange for a financial guaranty or loan. In this case, the
    joint venture’s decision to cap WB Partners’ share at a rate
    apparently plucked from thin air shows that the profit-sharing
    agreement was not bona fide. The absence of a good-faith
    profit-sharing agreement distinguishes this case from
    DJB HOLDING CORP. V. CIR                    31
    Maxwell and Stevens Brothers, and leaves Taxpayers’
    position unsupported by substantial authority. See 
    Treas. Reg. § 1.6662-4
    (d)(3)(ii).
    B. Taxpayers May Not Claim Reasonable Reliance on
    Their Accountant’s Opinion Because the
    Accountant Was Not Involved in Designing the
    NTC Joint Venture’s Structure.
    Reliance on professional advice may establish reasonable
    cause and good faith. 
    Treas. Reg. § 1.6664-4
    (b)(1). The Tax
    Court requires a taxpayer to prove three elements in order to
    show that reliance on advice was reasonable: “(1) The adviser
    was a competent professional who had sufficient expertise to
    justify reliance, (2) the taxpayer provided necessary and
    accurate information to the adviser, and (3) the taxpayer
    actually relied in good faith on the adviser’s judgment.”
    Neonatology Assocs., P.A. v. Comm’r, 
    115 T.C. 43
    , 99
    (2000). Once the Commissioner produces evidence showing
    that an accuracy-related penalty applies, the burden of
    proving the existence of reasonable cause and good faith falls
    on the taxpayer. Higbee v. Comm’r, 
    116 T.C. 438
    , 449
    (2001); cf. Sparkman, 
    509 F.3d at 1161
     (noting that the
    taxpayer bears the burden of overturning the Commissioner’s
    imposition of a negligence penalty under 
    26 U.S.C. § 6662
    ).
    Taxpayers argued before the Tax Court that they
    reasonably relied on the advice of their accountant in
    deciding how to treat the proceeds from the NTC Joint
    Venture. The Tax Court noted that the accountant had not
    participated in any way in structuring the joint venture or any
    of the entities that comprised it, but merely prepared
    Taxpayers’ tax returns based on information given him.
    Accordingly, the court found that Taxpayers had not supplied
    32              DJB HOLDING CORP. V. CIR
    the accountant with “all the necessary and accurate
    information,” and therefore that their reliance on the
    accountant’s tax returns was not reasonable.
    Taxpayers argue that the Tax Court clearly erred in failing
    to specify what necessary information they neglected to
    provide to the accountant. They assert that the accountant
    was “fully aware of the NTC Joint Venture and the allocation
    of income between WCI and WB Partners.”
    The Tax Court did not clearly err. “The mere fact that a
    certified public accountant has prepared a tax return does not
    mean that he or she has opined on any or all of the items
    reported therein.” Neonatology Assocs., 
    115 T.C. at 100
    .
    Nothing in the record suggests that the accountant knew
    Barone’s reasons for erecting the NTC Joint Venture,
    information the accountant would need in order to opine on
    its validity for tax purposes. See 
    Treas. Reg. § 1.6664
    -
    4(c)(1)(i) (listing the taxpayer’s purpose for a transaction as
    information the adviser must consider). More importantly,
    nothing in the record indicates that Taxpayers even asked the
    accountant for such an opinion. Instead, the record reveals
    only that the accountant prepared tax returns for the entities
    involved in the joint venture based on data supplied to him.
    Taxpayers have not met their burden of showing reasonable
    reliance on the accountant’s advice. See 
    Treas. Reg. § 1.6664-4
    (b)(1); Higbee, 
    116 T.C. at 449
    .
    DJB HOLDING CORP. V. CIR                    33
    C. Taxpayers Cannot Show That the Understatement
    of Income Was Due to a Reasonable
    Misunderstanding of Tax Law Because the
    Principles Governing Whether a Partnership Is
    Valid Are Well Settled.
    A taxpayer may show reasonable cause and good faith
    where the law governing its position “w[as] not settled” when
    the taxpayer asserted it. See Patel v. Comm’r, 
    138 T.C. 395
    ,
    417 (2012) (finding that a taxpayer reasonably claimed a
    deduction where the law governing the deduction’s
    availability was in an “uncertain state”). Taxpayers argue
    that their position that the NTC Joint Venture was a valid
    partnership is reasonable because the law governing it is
    complex. They have missed the point of Patel. The law may
    be complex, but it is not unsettled. The Luna factors have
    been the law for fifty years. See Luna, 
    42 T.C. at 1067
    ; see
    also Bergford v. Comm’r, 
    12 F.3d 166
    , 168–69 (9th Cir.
    1993) (applying the Luna factors). Taxpayers offer no
    authority for their suggestion that the complexity of the Luna
    factors alone should excuse their failure to conduct the NTC
    Joint Venture as a valid partnership.
    We conclude that the Tax Court did not err in upholding
    the Commissioner’s assessment of accuracy-related penalties.
    CONCLUSION
    WB Partners offered nothing to the NTC Joint Venture
    that it was not already contractually obligated to provide, and
    WCI’s arbitrary reduction of WB Partners’ share of the
    profits demonstrated that the parties did not intend to adhere
    to the terms of the joint venture agreement. The Tax Court
    therefore did not clearly err in finding that WCI and WB
    34              DJB HOLDING CORP. V. CIR
    Partners did not intend to operate the joint venture as a bona
    fide partnership, and taxing all profits from the venture as
    income to WCI accordingly. See Luna, 
    42 T.C. at 1077
    –79;
    Culbertson, 
    337 U.S. at 742
    .
    Further, though Barone and Watkins and their holding
    corporations agreed to supply services to WB Partners,
    Barone and Watkins were entitled to terminate their
    employment with ninety days’ notice. Because Barone and
    Watkins could leave WB Partners and provide services to
    another environmental remediation company at any time,
    their agreement not to compete with Kuranda may not be
    imputed to WB Partners. The Tax Court therefore did not
    clearly err in assigning WB Partners no portion of the $3.4
    million proceeds of the noncompetition agreement. See
    Beals’ Estate, 
    82 F.2d at 270
    ; Cox, 71 F.2d at 988;
    Culbertson, 
    337 U.S. at
    739–40.
    Finally, because Taxpayers have identified no substantial
    authority or reasonable cause for their positions, the Tax
    Court did not commit reversible error in assessing an
    accuracy-related penalty. See 
    26 U.S.C. §§ 6662
    (a), (b)(2),
    (d)(2)(B)(i), 6664(c)(1).
    The decisions of the Tax Court are AFFIRMED.
