Tax Court in Brief | Chapin v. Comm’r | Section 183 Horse Breeding, Bank Deposits, and a Split Penalty
Chapin v. Commissioner, T.C. Memo. 2026-76 | August 27, 2026 | Vasquez, J. | Dkt. Nos. 15018-16, 25413-16, 26117-16
Short Summary
Frank Chapin ran an accounting practice in Sandpoint, Idaho, from 1970 until his death in May 2026, preparing at least 200 client returns a year for local farmers, loggers, and small business owners. Sydney Gutierrez-Chapin grew up on an Illinois farm, bought a 120-acre Idaho ranch in 1982, and took veterinary courses through the University of Idaho Extension Service. They handled the ranch work themselves and ran the accounting office together.
By 1995 the ranching operation covered more than 300 acres and carried 160 head of cattle and 43 horses. A chapter 11 filed in 2002 converted to chapter 7 in 2003, and by the end of 2004 the cattle, the equipment, and nearly all of the land were gone. They kept breeding Appaloosas and Quarter Horses on a 30-acre parcel repurchased from the bankruptcy estate.
The IRS examined 2009 through 2014, reconstructed income by the bank deposits method after a judicial summons, disallowed essentially every deduction across the accounting practice, three LLCs, a family trust, and the Schedule F horse activity, and prepared substitutes for return for the two years the couple never filed. The deficiencies for 2009 through 2012 alone ran from $232,901 to $333,212.
The Court sustained most of the disallowances, adjusted the income reconstruction on the facts, held that the horse breeding was engaged in for profit, and split the accuracy-related penalties by category of item.
Key Issues
Whether respondent properly reconstructed unreported Schedule C gross receipts and Schedule E rental income using the bank deposits method, and which deposits represented nontaxable client funds.
Whether petitioners substantiated cost of goods sold, Schedule C deductions, passthrough deductions and losses from three LLCs and a family trust, net operating loss carryovers, and capital loss carryovers.
Whether the horse breeding activity was engaged in for profit within the meaning of section 183.
Whether petitioners are liable for additions to tax under sections 6651(a)(1), 6651(a)(2), and 6654, and for accuracy-related penalties under section 6662(a).
Primary Holdings
The bank deposits method was a reasonable reconstruction, but specific deposits came out of gross receipts: trust checks for an elderly client, a $4,450 estate payment, and the full $149,025 real estate closing check deposited on behalf of a client — not merely the $48,000 respondent had conceded as disbursed. Client tax refunds, client employment tax funds, insurance proceeds, and a $19,602 check payable to the couple’s daughter also came out.
Petitioners were entitled to modest additional amounts of COGS and Schedule C deductions where the ledger and testimony established reimbursements to family members who worked in the office, and to $312 of the $2,205 of 2009 client meal expenses under the section 274(n) 50% limitation. The balance of the disallowances was sustained.
The Willows passthrough loss failed for want of proof of outside basis, and the Chapin Family Living Trust losses of $57,671 and $21,975 failed because the record contained no trust agreement, no returns, and no Schedules K–1.
Petitioners engaged in horse breeding for profit. The Schedule F activity survives section 183, though the associated deductions were allowed only to the extent respondent had conceded them.
All net operating loss and capital loss carryovers were disallowed, and respondent’s determination of a $48,810 capital gain on the 2010 sale of a 20-acre parcel was sustained.
The section 6651(a)(1), 6651(a)(2), and 6654 additions were sustained. The section 6662(a) penalties were sustained in part — on the section 274(d) items, the NOLs, and the S&F Schedule E deductions — and rejected as to the income adjustments and the remaining Schedule C and E deductions.
Key Points of Law
Where a taxpayer fails to keep adequate books and records, section 446(b) permits the Commissioner to determine income by any method that clearly reflects it, and he has latitude in choosing the method. Petzoldt v. Commissioner, 92 T.C. 661, 693 (1989). The bank deposits method assumes deposits are taxable, but the Commissioner must account for nontaxable sources of which he has knowledge, and the taxpayer bears the burden of proving a nontaxable source. Clayton v. Commissioner, 102 T.C. 632, 645–46 (1994); DiLeo v. Commissioner, 96 T.C. 858, 868–69 (1991).
Cost of goods sold reduces gross receipts rather than operating as a deduction and is not subject to the section 162 limits, Metra Chem Corp. v. Commissioner, 88 T.C. 654, 661 (1987), but it still has to be substantiated. King v. Commissioner, T.C. Memo. 1994-318.
Section 704(d) caps a partner’s loss deduction at outside basis, and proof of basis is a specific fact the taxpayer must establish. Sennett v. Commissioner, 80 T.C. 825, 829 (1983); O’Neill v. Commissioner, 271 F.2d 44, 50 (9th Cir. 1959). The petitioners argued the IRS had to audit Willows at the partnership level before touching the loss. Willows fell within the TEFRA small partnership exception of section 6231(a)(1)(B), and outside basis is a partner-level determination in any event. Greenwald v. Commissioner, 142 T.C. 308, 316–17 (2014).
Tax returns are statements of a taxpayer’s position and do not substantiate the deduction they report, including the amount of an NOL carried forward. Sparkman v. Commissioner, 509 F.3d 1149, 1156–57 (9th Cir. 2007); Wilkinson v. Commissioner, 71 T.C. 633, 639 (1979). The same rule reaches Schedules K–1. Baker v. Commissioner, T.C. Memo. 2008-247. To carry a capital loss forward, a taxpayer must show that a loss was incurred, when, that it is deductible, its character, and the capital gains in the intervening years. Widemon v. Commissioner, T.C. Memo. 2004-162.
On section 183, the Ninth Circuit requires that the profit objective be the predominant, primary, or principal one. Wolf v. Commissioner, 4 F.3d 709, 713 (9th Cir. 1993). Treasury Regulation § 1.183-2(b) supplies nine nonexclusive factors, and objective facts carry more weight than a taxpayer’s statement of intent.
The factors the Court found decisive here were time and effort, expertise, financial status, and personal pleasure. Both petitioners had worked livestock since childhood. Mrs. Gutierrez-Chapin performed most of the routine veterinary care. They monitored foaling horses four and five times a night, and both had been injured by horses. Losses ranging from $9,876 to $22,740 produced tax savings too modest against the accounting practice’s income to suggest a shelter. And on recordkeeping the Court was direct: the records “left something to be desired,” but that defect “does not negate petitioners’ profit motive.” Section 183 “does not require that taxpayers operate their ventures with perfect business acumen.” Huff v. Commissioner, T.C. Memo. 2021-140.
Reliance on a professional excuses a late filing only where the professional advised on a substantive question, such as whether a return had to be filed at all. United States v. Boyle, 469 U.S. 241, 250–51 (1985). Mr. Chapin first said his bankruptcy lawyers told him not to file, then testified he had no recollection of any such advice. The Court noted that even crediting the first version, the chapter 7 trustee’s final report came in March 2011 and the 2009 return did not arrive until May 2012.
A section 6020(b) substitute for return is treated as the taxpayer’s return for section 6651(a)(2) purposes and disregarded for section 6651(a)(1) purposes. §§ 6651(g)(1), (2). The combination of Form 13496, Form 4549–A, and Form 886–A satisfied the validity requirements of Rader v. Commissioner, 143 T.C. 376, 382 (2014). Section 6654 carries no general reasonable cause exception. Rader, 143 T.C. at 390; Treas. Reg. § 1.6654-1(a)(1).
Insight
Two things in this opinion are worth carrying into your next examination.
The first is what saved the horse operation. Nothing about the Chapins’ recordkeeping was good. The Court said so. But what it credited instead was physical evidence of effort that no tax planner would fabricate — the night calving, the injuries, the club memberships that required registering foals and filing annual breeding reports, decades of doing this work personally. A section 183 case is often argued as a records case, and this one is a useful reminder that the nine factors are not a documentation test. When the losses are small enough that they buy the taxpayer very little, and the labor is hard enough that nobody would do it for fun, factors three, eight, and nine can carry a case that factor one cannot. Huff, the miniature donkey case the Court cited, reached the same result on the same logic.
The second is the penalty split. Judge Vasquez did not decide negligence year by year. He sorted it by category of item. Where Mr. Chapin’s monthly reconciliations, ledger categories, and allocation of expenses among personal, practice, and farm showed a reasonable attempt to comply, no penalty attached — and the Court explicitly attributed the weak trial presentation of that evidence to the petitioners’ age and the passage of time rather than to carelessness. Where the items were governed by the strict substantiation rules of section 274(d), or consisted of carryovers with no underlying documents at all, the penalty stuck. An accountant who fell “woefully short” of section 274(d) got no benefit of the doubt on those items and full benefit of the doubt on the rest.
That is a template. On accuracy-related penalties, the argument to make is not that the return was reasonable, which invites a global answer, but that particular adjustments arose from a good-faith method while others did not. Concede the section 274(d) items and defend the rest.
A caution on the years the couple never filed. The 2013 and 2014 substitutes for return carried failure-to-file, failure-to-pay, and estimated tax additions, and section 6654 gave them nowhere to go. A bankruptcy that discharged in 2008 and closed in 2011 does not explain a 2015 payment failure, and the Court said as much. Filing late is expensive. Not filing is worse.
