MEMORANDUM FINDINGS OF FACT AND OPINION
FUNG, Judge: Petitioner challenges a Notice of Deficiency
(Notice) issued by the Internal Revenue Service (respondent) for tax
years ending June 30, 2018 and 2019. 1 For tax year 2018, respondent
determined a tax deficiency of $67,354 and an accuracy-related penalty
under section 6662(a) 2 of $13,471. For tax year 2019, respondent
determined a tax deficiency of $24,844 and an accuracy-related penalty
under section 6662(a) of $4,969. After concessions, two issues remain for
decision: (1) whether petitioner may deduct $118,302 in subcontractor
expenses for tax year 2019 and (2) whether petitioner is liable for the

[*2] section 6662(a) penalty for tax year 2018. 3 We hold that petitioner
has not substantiated the claimed subcontractor-expense deduction and
is therefore not entitled to that deduction for tax year 2019. We further
hold that petitioner is liable for the section 6662(a) penalty for tax year
2018.
FINDINGS OF FACT
Some of the facts are stipulated and are so found. They are
incorporated herein by this reference. Other facts are drawn from sworn
testimony and the documentary evidence admitted at trial. Petitioner’s
principal place of business was in California when the Petition was
timely filed. 4
I. Petitioner’s Business Operations
Petitioner is a closely held C corporation with annual gross
receipts of $4.1 million for tax year 2019. Petitioner sells glass shower
doors and enclosures through third-party retail platforms, such as Home
Depot, Wayfair, and Houzz. During the tax years at issue, petitioner’s
principal place of business was in San Diego, California, and petitioner
maintained warehouses for inventory in both California and Texas.
Petitioner’s two shareholder-officers manage its operations: Ryan
Thatcher, as president, owns 80%, and Nidal Hanna, as vice president,
owns 20%. Mr. Thatcher and Ms. Hanna were married to each other
during the tax years at issue. Both worked for petitioner full time,
managing every aspect of the day-to-day operations, including sales,
inventory purchasing, employee management, and customer attraction
and retention.
During the tax years at issue, petitioner had approximately ten
employees. Among them was Mallory Copeland, an accounting manager
who oversaw, and continues to oversee, payroll and employee
compensation, including compensation paid to Mr. Thatcher and Ms.
Hanna, as shareholder-officers, and to employees receiving Forms W–2,
Wage and Tax Statement. Ms. Copeland managed petitioner’s accounts
payable and accounts receivable using QuickBooks software, later
3 On October 16, 2025, the parties filed a Stipulation of Settled Issues resolving
all issues for tax year 2018, except petitioner’s liability for the section 6662(a) penalty.
Respondent also conceded the section 6662(a) penalty for tax year 2019.
4 Absent any stipulation to the contrary, our decision in this case is appealable
to the U.S. Court of Appeals for the Ninth Circuit. See I.R.C. § 7482(b)(1)(B), (2).

Petitioner’s certified public accountant (CPA) during the years at issue,
Ahuja & Clark, PLLC (Ahuja & Clark), also had access to petitioner’s
QuickBooks records. After Mr. Thatcher and Ms. Hanna, Ms. Copeland
was petitioner’s next highest compensated employee.
II. 2019 Tax Reporting
Petitioner timely filed its Forms 1120, U.S. Corporation Income
Tax Return, for 2018 and 2019. On Line 12 of its 2019 Form 1120,
petitioner reported $71,250 in officer compensation. Petitioner’s
accompanying 2019 Form 1125–E, Compensation of Officers, reported
that the compensation paid to each of Mr. Thatcher and Ms. Hanna was
$35,625. Petitioner issued Forms W–2, reporting wages of $92,712 to
Mr. Thatcher and $73,962 to Ms. Hanna for 2019. Petitioner also
claimed a deduction for $173,974 in subcontractor fees. That figure
presumably included $109,819 of the claimed subcontractor fees as
reported by Mr. Thatcher and Ms. Hanna—$98,774 to Mr. Thatcher and
$11,045 to Ms. Hanna. Petitioner did not issue either Mr. Thatcher or
Ms. Hanna Form 1099 for 2019 for these amounts.
On their 2019 joint return, Mr. Thatcher and Ms. Hanna reported
$166,674 in wages from petitioner and $109,819 in “Other income” from
petitioner, the same subcontractor fee amounts described above. On
August 18, 2022, respondent issued petitioner the Notice, wherein
respondent disallowed $118,302 of petitioner’s claimed $173,974
subcontractor-expense deduction for lack of substantiation. 5 On
November 9, 2022, petitioner timely filed the Petition.
5 In summary, petitioner contends that the following amounts were paid to
Mr. Thatcher and Ms. Hanna for 2019:
Officer Purported
Recipient W–2 Wages
Compensation Subcontractor Fees
Ryan Thatcher $35,625 $92,712 $98,774
Nidal Hanna 35,625 73,962 11,045
Total 71,250 166,674 109,819

[*4] OPINION
I. Burden of Proof
The Commissioner’s determinations in a Notice of Deficiency are
generally presumed correct, and the taxpayer bears the burden of
proving them erroneous. See Rule 142(a); Welch v. Helvering, 290 U.S.
111, 115 (1933). The taxpayer can shift this burden to the Commissioner
by satisfying specified conditions set forth in section 7491(a), including
providing credible evidence for material facts. Section 7491(a) applies,
however, only if the taxpayer complies with all substantiation and
recordkeeping requirements under the Code.
Deductions are a matter of legislative grace, and taxpayers bear
the burden of proving entitlement to each deduction claimed.
INDOPCO, Inc. v. Commissioner, 503 U.S. 79, 84 (1992). Doing so
requires showing both that a statute authorizes the deduction and that
the taxpayer maintained sufficient records substantiating income and
expenses. See I.R.C. § 6001; Treas. Reg. § 1.6001-1(a). Adequate
substantiation must establish the nature, amount, and purpose of a
claimed deduction. See, e.g., Higbee v. Commissioner, 116 T.C. 438, 440
(2001). When evidence presented at trial is insufficient to support the
claim that a particular expense is deductible, we must sustain the
Commissioner’s determination and disallow the deduction. Rogers v.
Commissioner, T.C. Memo. 2014-141, at *16.
The Notice disallowed deductions of $118,302 in subcontractor
expenses for 2019. Petitioner contends that this amount was
substantiated at trial through testimony, accounting records, and a
payee statement. But at trial petitioner did not provide any testimony,
accounting records, or statements to show any subcontractor services in
2019. Therefore, the burden of proof remains with petitioner.
II. Section 162 Deduction
A taxpayer, including a corporation, can deduct “all the ordinary
and necessary expenses paid or incurred during the taxable year in
carrying on any trade or business,” including a reasonable allowance for
salaries or other compensation for personal services “actually rendered.”
I.R.C. § 162; accord O.S.C. & Assocs. v. Commissioner, 187 F.3d 1116,
1119 (9th Cir. 1999), aff’g T.C. Memo. 1997-300; Treas. Reg. §§ 1.162-
7(a), 1.162-9. Whether an expenditure satisfies the requirements for
deductibility under section 162 is a question of fact. Commissioner v.
Heininger, 320 U.S. 467, 475 (1943). As stated above, petitioner bears
5
[*5] the burden of substantiating the expenses underlying its claimed
section 162 deductions. See generally Sparkman v. Commissioner, 509
F.3d 1149, 1159 (9th Cir. 2007), aff’g T.C. Memo. 2005-136; Treas. Reg.
§ 1.6001-1(a).
As to compensation, the Ninth Circuit applies a two-prong test for
deductibility under section 162(a)(1): (1) the amount of compensation
must be reasonable; and (2) the payments must be made with the intent
to compensate for services rendered. O.S.C. & Assocs. v. Commissioner,
187 F.3d at 1119–20; see also Elliotts, Inc. v. Commissioner, 716 F.2d
1241, 1243 (9th Cir. 1983), rev’g T.C. Memo. 1980-282. The parties agree
that the first prong is not at issue. 6 Thus, at issue is only whether
petitioner paid the subcontractor fees with the intent to compensate Mr.
Thatcher and Ms. Hanna for their supposed services. 7 As the parties
6 At trial and in his Opening Brief, filed April 13, 2026, respondent conceded
that reasonableness of the compensation is not at issue. Further, the Notice disallowed
the subcontractor expenses only on the ground of substantiation, not for the
reasonableness of the amount.
7 The parties devoted substantial portions of their briefs and trial
presentations to whether the payments reflected compensatory intent or, instead,
constituted disguised dividends to shareholder-officers, so we briefly note those
arguments for completeness. See Menard, Inc. v. Commissioner, 560 F.3d 620, 621–22
(7th Cir. 2009) (discussing the use of compensation deductions to disguise dividends),
rev’g T.C. Memo. 2004-207; O.S.C. & Assocs. v. Commissioner, 187 F.3d at 1120
(setting forth numerous factors for courts to consider when evaluating compensatory
intent).
To show that petitioner’s reported subcontractor expenses were disguised
dividends, respondent relied in part on petitioner’s “Shareholder Distributions”
spreadsheet (Exhibit 1005-R), which includes a June 30, 2018, entry stating “to reclass
Distributions to Contract Labor,” and petitioner’s subcontractor spreadsheet (Exhibit
1006-R), which includes a January 30, 2019, entry stating “Reclassing Ryan’s
shareholder distributions to subcontractor for 2020 1099.” In response, petitioner’s
counsel contended that those entries were bookkeeping errors and not indicative of
petitioner’s intent to disguise dividends as subcontracting payments. However, Ms.
Copeland did not offer any testimony regarding these specific line items, except to
confirm their existence. Though we admitted these Exhibits and allowed the parties a
robust discussion, we did not rely on them in our decision.
We also note some curiosities from the parties’ documentary evidence
presented and Ms. Copeland’s testimony in the light of some of the factors the Ninth
Circuit considers in determining compensatory intent. See O.S.C. & Assocs. v.
Commissioner, 187 F.3d at 1120. The parties stipulated, and Ms. Copeland testified,
that petitioner had never declared or paid dividends or a distribution. Nor was there
any evidence of a bonus plan or bonus structure. The payments closely tracked Mr.
Thatcher’s and Ms. Hanna’s ownership percentages, which might suggest a
distribution. No employees other than the two shareholder-officers received payments
outside their Form W–2 wages, and 2019 was the only year in which Mr. Thatcher and
Ms. Hanna received both Form W–2 wages and purported subcontractor fees; but Ms.
6
[*6] agree, respondent denied the section 162 deduction for
subcontractor expenses solely for lack of substantiation. Because
petitioner also failed to substantiate such subcontractor expenses, we
need not decide compensatory intent.
Petitioner contends that Ms. Copeland’s testimony established
that the services Mr. Thatcher and Ms. Hanna provided were
subcontractor expenses deductible by petitioner. But Ms. Copeland’s
only testimony describing Mr. Thatcher’s services concerned his day-to-
day work for the petitioner—“manag[ing] every aspect of the company,
customers, inventory buying, all of it”—including managing employees
and “responsibility for attracting or retaining customers.” She similarly
did not offer any specific information about services provided by Ms.
Hanna. And Ms. Copeland testified that she did not see Mr. Thatcher or
Ms. Hanna involved in the business in any capacity beyond their day-
to-day operations work. Notably, neither performed any groundskeeping
or maintenance work for petitioner.
A corporation, like any other taxpayer, is free to structure its
business operations, including compensation arrangements, as best fits
its needs. See generally Gregory v. Helvering, 293 U.S. 465, 469 (1935);
Jones v. Helvering, 71 F.2d 214, 217 (D.C. Cir. 1934), rev’g and
remanding 18 B.T.A. 1225 (1930). We recognize that “[a]ll businesses
are different, all CEOs are different, and all compensation packages for
CEOs are different.” Menard, Inc. v. Commissioner, 560 F.3d at 623.
Thus, petitioner was free to make additional payments to petitioner’s
officers, Mr. Thatcher and Ms. Hanna, for subcontractor fees for
additional services actually rendered. The record does not contain any
documents or any testimony showing that such an arrangement existed.
For 2019, Mr. Thatcher and Ms. Hanna received Form W–2 wages
from petitioner, presumably for the services Ms. Copeland described.
Copeland was unable to explain why the payments were structured in that manner for
2019 but not for other years. Finally, neither Mr. Thatcher nor Ms. Hanna testified on
behalf of petitioner’s compensatory intent.
In these circumstances the Court can draw only a limited inference regarding
compensatory intent and cannot determine on this record whether the payments were
intended as compensation or as disguised dividends to petitioner’s shareholder-
officers. We express no view on the proper characterization of the payments, but even
if petitioner could establish the requisite compensatory intent to satisfy the
requirements of section 162(a)(1), petitioner has nonetheless failed to substantiate the
reported expense. Accordingly, we do not reach the parties’ competing arguments
regarding compensatory intent, disguised dividends, or the significance of the
bookkeeping entries reflected in Exhibits 1005-R and 1006-R.
7
[*7] And Ms. Copeland further testified that she was unaware of any
subcontractor agreements between petitioner and either Mr. Thatcher
or Ms. Hanna. The parties also stipulated that Mr. Thatcher and Ms.
Hanna were not issued any Forms 1099, which one would presumably
receive for subcontractor services. Ms. Copeland likewise had no
knowledge of the nature of any subcontractor services that Mr. Thatcher
or Ms. Hanna may have or could have performed, other than their day-
to-day operational duties. In contrast, when Ms. Copeland issued Forms
1099 to different employees, she was aware of the subcontractor work
those employees performed.
Petitioner points to the 2019 joint return of Mr. Thatcher and Ms.
Hanna, on which they reported the $109,819 as “Other income” and paid
employment taxes, arguing that this substantiates petitioner’s
entitlement to deduct the same amount. How a shareholder reports an
item on a personal tax return does not control how the corporation
reports that same item on its own tax return because a corporation is
generally recognized as a tax entity separate from its shareholders.
Moline Props., Inc. v. Commissioner, 319 U.S. 436, 438–39 (1943). Mr.
Thatcher and Ms. Hanna’s tax position thus has no bearing on whether
petitioner may deduct the expense. 8 “A taxpayer is free to adopt [any]
organization for his affairs as he may choose and having elected to do
some business as a corporation, he must accept the tax disadvantages.”
Higgins v. Smith, 308 U.S. 473, 477 (1940); see also Moline Props., Inc.
v. Commissioner, 319 U.S. at 439.
Petitioner presented no testimony or other evidence regarding the
nature, contractual agreement, amount, or provider of the purported
subcontractor services. It failed to produce any business records, payroll
records, contracts, invoices, Forms 1099, or other reliable documents in
support of its position. Ms. Copeland’s testimony as to Mr. Thatcher’s
and Ms. Hanna’s general duties does not substantiate the subcontractor
8 Petitioner’s counsel argued that the reporting of subcontractor expenses was
a case of worker misclassification and that section 3509 provides a remedy such that
there is no loss to the Treasury for an employer’s failure to pay withholding taxes.
Section 3509 determines an employer’s liability for its failure to withhold employment
taxes “by reason of treating [an] employee as not being an employee.” When that
happens, the employer is liable for an increased percentage of the withholding taxes
and Social Security taxes required to be deducted or imposed. I.R.C. § 3509(a). Section
3509 does not turn amounts that would otherwise not be subject to withholding tax,
such as contractor expenses, into deductible Form W–2 wages just because the Code
provides a mechanism to hold an employer liable in an actual worker misclassification
situation. We note that petitioner did not offer any testimony or other evidence that it
misclassified Mr. Thatcher or Ms. Hanna.
8
[*8] expenses that petitioner’s counsel represented it would prove. Thus,
we find that petitioner is not entitled to deduct its subcontractor
expenses. 9
III. Section 6662(a) Penalty
Respondent determined an accuracy-related penalty for 2018 on
the basis of a substantial understatement of income tax under section
6662(a) and (b)(2). Alternatively, respondent contends that petitioner is
liable on the grounds of negligence or disregard of rules and regulations.
See I.R.C. § 6662(a) and (b)(1).
Section 6662(a) imposes a 20% accuracy-related penalty on any
portion of an underpayment of tax required to be shown on a return that
is attributable, as relevant here, to negligence or disregard of rules or
regulations under section 6662(b)(1) or to a substantial understatement
of income tax under section 6662(b)(2). For a subchapter C corporation
such as petitioner, an understatement is substantial if it exceeds the
lesser of 10% of the tax required to be shown on the return for the tax
year (or, if greater, $10,000) or $10,000,000. I.R.C. § 6662(d)(1)(B). Only
one accuracy-related penalty may be applied with respect to any given
portion of an underpayment, even if that portion could be penalized on
more than one ground under section 6662(b). Treas. Reg. § 1.6662-2(c).
The tax shown on petitioner’s 2018 Form 1120 was $92,775. The
amount of tax required to be shown on the return was $107,775. 10 The
resulting understatement of income tax for 2018 exceeds both 10% of the
tax required to be shown on the return and $10,000 and is therefore
substantial.
The Commissioner generally bears the burden of production with
respect to a taxpayer’s liability for an accuracy-related penalty. I.R.C.
§ 7491(c). But section 7491(c) applies only to individuals, not
corporations, so respondent bears no burden of production here. See NT,
Inc. v. Commissioner, 126 T.C. 191, 195 (2006) (noting that section
7491(c) by its terms does not apply to corporations). 11 Because
9 Petitioner did not address the $8,483 difference between the $118,302
disallowed for subcontractor expenses in the Notice and the $109,819 it disputed at
trial and on brief. Similarly, it failed to substantiate the remaining $8,483.
10 This is the amount recomputed for 2018 from the Stipulation of Settled
Issues, filed October 16, 2025.
11 Respondent provided a Civil Penalty Approval Form, which was admitted
into evidence as Exhibit 4-J, to show that respondent complied with section 6751(b).
9
[*9] respondent has no burden of production, petitioner bears the
burden of proving that respondent’s determination is incorrect or that
petitioner has an affirmative defense such as reasonable cause. See
I.R.C. § 6664(c); Rule 142(a); Higbee, 116 T.C. at 446–49; Treas. Reg.
§ 1.6664-4(a).
A taxpayer may avoid section 6662 penalties by showing there
was a reasonable cause for the underpayment and the taxpayer acted in
good faith. I.R.C. § 6664(c)(1); Higbee, 116 T.C. at 448. We determine
whether reasonable cause exists on a case-by-case basis, considering all
pertinent facts and circumstances. Treas. Reg. § 1.6664-4(b)(1); see also
Patel v. Commissioner, 165 T.C. 171, 207 (2025). Petitioner bears the
burden of proving that reasonable cause precludes application of the
negligence and substantial understatement penalties. See Patel, 165
T.C. at 207.
“Reasonable cause requires that the taxpayer have exercised
ordinary business care and prudence as to the disputed item.”
Neonatology Assocs., P.A. v. Commissioner, 115 T.C. 43, 98 (2000), aff’d,
299 F.3d 221 (3d Cir. 2002). Good-faith reliance on the advice of an
independent, competent professional as to the tax treatment of an item
may satisfy this requirement. Id.; Treas. Reg. § 1.6664-4(b)(1) (“Reliance
on an information return or on the advice of a professional tax advisor
or an appraiser does not necessarily demonstrate reasonable cause and
good faith.”); see also United States v. Boyle, 469 U.S. 241, 250 (1985).
The taxpayer must also reasonably rely on and act in good faith with
respect to the advice. Treas. Reg. § 1.6664-4(b)(1) (“Reliance on an
information return, professional advice, or other facts, however,
constitutes reasonable cause and good faith if, under all the
circumstances, such reliance was reasonable and the taxpayer acted in
good faith.”). To reasonably rely on a qualified professional’s advice, the
taxpayer must show that (1) the adviser was a competent professional
with sufficient expertise to justify reliance; (2) the taxpayer provided
necessary and accurate information to the adviser; and (3) the taxpayer
However, petitioner did not dispute at trial or on brief that respondent met the
requirements of section 6751(b). Because the Civil Penalty Approval Form was signed
by the immediate supervisor of the individual making the penalty determination
before the issuance of the Notice, we agree that respondent complied with section
6751(b). See Laidlaw’s Harley Davidson Sales, Inc. v. Commissioner, 29 F.4th 1066,
1074 (9th Cir. 2022) (holding that written supervisory approval is required before the
assessment of the penalty or before the relevant supervisor loses discretion to approve
the penalty assessment), rev’g and remanding 154 T.C. 68 (2020).
10
[*10] actually relied in good faith on the adviser’s judgment.
Neonatology Assocs., 115 T.C. at 99.
Petitioner argues that penalties are unwarranted because it
“reasonably relied on a qualified professional tax adviser, identified in
the signature block on the taxpayer returns; The positions taken are
supported by established legal authority as cited above.” Petitioner also
contends that “[t]here is no evidence of negligence, disregard of rules, or
intent to understate tax,” and that, under section 6664(c), “[r]eliance on
competent professionals constitutes reasonable cause and good faith.”
These sentences constitute the bulk of petitioner’s arguments on brief
as to why penalties should not apply.
The record is devoid of any testimony or other evidence of any
information petitioner provided to an adviser regarding its tax position.
At trial petitioner introduced no evidence showing that it sought or
received any advice from Ahuja & Clark, the paid preparer identified on
petitioner’s return, regarding the filing of its returns. There is no
evidence that petitioner disclosed to Ahuja & Clark all the relevant facts
and circumstances related to its returns or that Ahuja & Clark provided
any advice at all. See Treas. Reg. § 1.6664-4(b)(1). And if any advice was
given, there is no evidence as to whether that advice was based on
reasonable or factual assumptions or that petitioner reasonably relied
on such advice in good faith. See I.R.C. § 6664(c)(1); Treas. Reg. § 1.6664-
4(a). “[S]tatements in briefs . . . do not constitute evidence.” Rule 143(c);
accord Niedringhaus v. Commissioner, 99 T.C. 202, 214 n.7 (1992).
Taxpayers must provide evidence at trial to support their claimed
position. See Rogers, T.C. Memo. 2014-141, at *15–16. Petitioner failed
to do so.
Petitioner’s sole witness, Ms. Copeland, was not asked about
petitioner’s tax filings or return positions, and her testimony did not
show that she would have had any interaction with Ahuja & Clark
regarding petitioner’s returns. She did not provide, and petitioner did
not introduce, the payee statement or accounting records referenced by
petitioner’s counsel as the definitive substantiation for petitioner’s
claimed subcontractor expenses. Petitioner’s counsel provided only the
following statement at trial to show petitioner was not negligent with
respect to its tax position: “He has an external CPA, and he has someone
professionally prepare his tax returns. So that to me does not seem like
a person who does not give due care to his tax reporting
11
[*11] responsibilities.” 12 No witness testified about any interaction with
any return preparer regarding the preparation of, or the positions taken
on, petitioner’s return.
Petitioner has therefore failed to identify any reasonable cause
for the underpayment. Simply hiring a tax preparer does not insulate a
taxpayer from the consequences of the tax positions on its return. See
Treas. Reg. § 1.6664-4(b)(1). We find that petitioner is liable for the
section 6662(a) accuracy-related penalty for 2018 due to a substantial
understatement of income tax. 13 See I.R.C. § 6662(b)(2), (d)(1)(B).
IV. Conclusion
For the reasons discussed above, we conclude that petitioner is
not entitled to a deduction of $118,302 for subcontractor expenses for
2019 and is liable for an accuracy-related penalty under section 6662(a)
for 2018 on the basis of a substantial understatement of income tax.
We have considered all of the arguments made by the parties, and
to the extent not addressed above, we conclude that they are moot,
irrelevant, or without merit.
To reflect the foregoing,
Decision will be entered under Rule 155.
12 We assume the “he” to which petitioner’s counsel refers is Mr. Thatcher.
Although Mr. Thatcher did not testify, we assume that, as an 80% shareholder-officer,
Mr. Thatcher had some responsibility for hiring a return preparer on behalf of
petitioner.
13 We therefore need not address whether petitioner is liable for the section
6662(a) penalty on the grounds of negligence or disregard of rules and regulations. See
I.R.C. § 6662(b)(1), (c).
