DAWN CHAPPELLE COTTMAN,

Petitioner

v.

COMMISSIONER OF INTERNAL REVENUE, Respondent

Docket No. 6978-23. Filed September 17, 2026.

Dawn Chappelle Cottman, pro se.

Victoria E. Cvek, Bradley C. Plovan, and Susan A. Bechtel, for respondent.

MEMORANDUM FINDINGS OF FACT AND OPINION

WAY, Judge: At issue in this case is whether petitioner, Dawn C.

Cottman, failed to report income on her Forms 1040, U.S. Individual Income Tax Return, for 2009, 2010, and 2011 (years at issue) and whether petitioner did so fraudulently.

On January 10, 2023, the Internal Revenue Service (respondent or Commissioner) issued a Notice of Deficiency (Notice) determining the following deficiencies and fraud penalties for the years at issue. 1

1 On January 10, 2023, respondent issued a separate Notice of Deficiency for

tax year 2012 but has conceded in full the deficiency and penalty for that year. Tax year 2012 will not be discussed further.

Served 09/17/26

[*2] Penalty Year Deficiency § 6663 2

2009 $124,998 $93,749 2010 265,837 199,378 2011 373,672 280,254

Respondent conceded that the deficiencies and penalties for 2009 and 2010 are lower than the amounts determined in the Notice because of subsequent downward revisions to petitioner’s unreported taxable income for those years. For 2009, after concessions, the amount of unreported taxable income at issue is $142,622 instead of $365,655. For 2010, after concessions, the amount of unreported taxable income at issue is $291,982 instead of $743,711. In the Rule 155 computations to follow, these revisions will affect both the deficiency and penalty calculations for 2009 and 2010. 3

Because the Notice was mailed after the limitations period for assessment under section 6501(a) had run, respondent’s assessments are predicated on proving the applicability of the fraud exception to the period of limitations under section 6501(c)(1).

This Court finds that respondent has met his burden of proving fraud by clear and convincing evidence for the years at issue. Consequently, and for the reasons stated herein, this Court will sustain the deficiencies and fraud penalties, taking into account respondent’s concessions described above.

FINDINGS OF FACT

Some of the facts have been deemed stipulated pursuant to Rule 91(f) and are so found. These facts are incorporated herein by this reference. Other facts are drawn from sworn testimony and evidence

2 Unless otherwise indicated, statutory references are to the Internal Revenue

Code, Title 26 U.S.C., in effect at all relevant times, regulation references are to the Code of Federal Regulations, Title 26 (Treas. Reg.), in effect at all relevant times, and Rule references are to the Tax Court Rules of Practice and Procedure. All monetary amounts are rounded to the nearest dollar.

3 Respondent also lists seven computational adjustments that flow from

respondent’s determinations of petitioner’s income. The applicability and extent of these adjustments depend on the outcome of this case and are thus relevant to the Rule 155 computations that follow.

[*3] admitted at trial. Petitioner resided in Maryland when she timely petitioned this Court. 4

I. Petitioner’s Tax Preparation Business

Petitioner solely owned and operated 40 AM Tax Service (40 AM), a tax return preparation business. Through 40 AM, petitioner prepared and filed approximately 1,219 federal and state income tax returns for clients in exchange for fees during the years at issue. Although petitioner provided these services, she did not have a Preparer Tax Identification Number, nor did she identify herself as a preparer on her clients’ returns.

As part of petitioner’s tax preparation activities, petitioner directed respondent to deposit her clients’ refunds into bank and credit union accounts controlled by petitioner. These included more than two dozen accounts with Navy Federal Credit Union, USAA Federal Savings Bank, and Atlantic Financial Federal Credit Union. Across the various accounts, petitioner was listed either as the individual account holder, trustee, or custodian, or as the business owner of 40 AM.

Petitioner’s primary source of income during the years at issue was 40 AM. Petitioner reported 40 AM’s income and expenses on Schedules C, Profit or Loss From Business, of her Forms 1040. Petitioner did not report as income the client refunds deposited into her accounts, nor did she maintain records of the refunds she alleges she withdrew to distribute to her clients.

II. Petitioner’s Criminal Case

On April 4, 2018, a federal grand jury in the U.S. District Court for the District of Maryland issued a superseding indictment charging petitioner with crimes related to her tax preparation business, specifically with respect to activities undertaken for tax years 2011 and 2012. Petitioner was indicted on one count of conspiracy to defraud the United States under 18 U.S.C. § 286, 5 six counts of filing false claims

4 Absent stipulation to the contrary, this case is thus appealable to the U.S.

Court of Appeals for the Fourth Circuit. See § 7482(b)(1)(A), (2).

5 Count 1 states that petitioner, “from in or about January 2009 until in or

about March 2013,” “added materially false information to the tax returns in order to fraudulently increase the size of the tax refund” and “prepared and filed income tax returns in other people’s names without their knowledge or consent in order to fraudulently obtain a tax refund,” in violation of 18 U.S.C. § 286.

[*4] under 18 U.S.C. § 287, three counts of wire fraud under 18 U.S.C. § 1343, three counts of aggravated identity theft under 18 U.S.C. § 1028A(a)(1) and (c)(5), and two counts of filing a false tax return under section 7206(1).

On May 22, 2018, a jury found petitioner guilty on 14 of these counts, including conspiracy to defraud the United States and both counts under section 7206(1). 6 On the basis of the factual allegations set forth in the superseding indictment, the jury found that from about January 2009 until about March 2013:

• Petitioner added materially false information to tax returns in order to increase the size of tax refunds. This information included fictitious income amounts, false work histories, and misrepresentations to support fraudulent claims for the Earned Income Tax Credit and education credits.

• Petitioner prepared and filed tax returns in other people’s names without their knowledge or consent in order to fraudulently claim tax refunds. Petitioner paid various individuals to obtain the birth dates, Social Security numbers, and other private information of these taxpayers.

• Petitioner directed the Internal Revenue Service to deposit the refunds into bank accounts that she controlled. On occasion, petitioner filed Forms 8888, Allocation of Refund, to split refunds with the individuals who provided her with confidential taxpayer information. 7

Petitioner served over three years in prison for these crimes.

6 Petitioner’s related appeals have been unsuccessful. See United States v.

Cottman, No. 21-6946, 2021 WL 4860716 (4th Cir. Oct. 19, 2021); United States v. Cottman, No. 22-7241, 2023 WL 334667 (4th Cir. Jan. 20, 2023).

7 This Court will treat these findings as established facts. See United States v.

Podell, 572 F.2d 31, 35 (2d Cir. 1978) (“It is well-settled that a criminal conviction, whether by jury verdict or guilty plea, constitutes estoppel in favor of the United States in a subsequent civil proceeding as to those matters determined by the judgment in the criminal case.”); see also United States v. Uzzell, 648 F. Supp. 1362, 1365 (D.D.C. 1986) (clarifying that, where “nothing in the record indicates that anything less than all of the specific acts alleged in the count were determined by the jury in reaching [the] verdict,” the guilty verdict conclusively establishes each specific act charged in that count).
