Transupport, Incorporated v. Commissioner of IRS, 882 F.3d 274

Transupport, a wholesaler of military-engine parts, used the gross-profit method (selecting a gross-profit percentage) instead of physical inventories to report cost of goods sold for tax years 2006–2008; its reported gross-profit percentages varied and lacked supporting records.
Harold Foote (founder) and his four sons (officers/employees) ran the company; Foote set high, equal salaries for each son ($575k in 2006; $675k in 2007; $720k in 2008) with the apparent goals of reducing taxable income and equal treatment.
Foote circulated offering materials (when contemplating a sale) claiming very high gross profits and inventory values (e.g., ~75% gross profit, inventory ~$100M at cost), which conflicted sharply with Transupport’s tax returns and internal summaries.
IRS audited and issued a notice of deficiency adjusting (1) cost of goods sold to reflect a 25% cost / 75% gross profit, (2) reductions to officer compensation deductions, and (3) penalties (fraud assessed originally; later fraud found not proven for earlier years but accuracy-related penalties upheld for 2006–2008).
Tax Court (after two proceedings) rejected the Commissioner’s fraud penalty for earlier years but upheld the deficiency for 2006–2008; Transupport appealed only the second opinion’s findings on reasonable compensation, inventory/gross-profit percentage, burden shifting, and the 20% accuracy-related penalty.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Reasonable compensation	Sons’ long service and managerial roles justify the salaries as reasonable	IRS compared compensation to similar officers and found salaries excessive; taxpayer failed to prove reasonableness	Court upheld IRS adjustment: Transupport failed to carry burden; no clear error in Tax Court’s findings
Burden of proof shift on compensation	Notice was arbitrary/excessive so burden should shift to IRS	Notice was rationally grounded by IRS methodology and evidence	No shift: Tax Court reasonably found IRS method not arbitrary
Cost of goods sold (75% gross profit)	75% figure inconsistent with prior Tax Court skepticism and Transupport’s evidence	Foote’s admissions, Honeywell inventory list, and poor recordkeeping support substantial understatement of inventory and justify 75% gross profit	Court affirmed Tax Court’s adoption of 75% gross profit; taxpayer failed to prove figures
20% accuracy-related penalty	Reliance on longtime CPA and prior audits shows reasonable cause and good faith	Foote’s own statements and internal figures show Transupport knew or should have known returns were inaccurate; reliance not reasonable where underlying representations were false	Penalty upheld: Tax Court did not clearly err in finding lack of reasonable cause/good faith
