Cohan Rule

Cohan, 8 AFTR 10552 (2nd Cir. 1930); Barton, TC Memo 2005-97

All is not lost for taxpayers who fail to maintain adequate business records, provided they can support that business expenses were, in fact, incurred.  However, as a taxpayer recently discovered, certain expenses must meet strict substantiation requirements.  But first, some brief history.

For tax years 1921 – 1923, George M. Cohan, a famous Broadway theatrical producer, had all of his unsubstantiated business deductions disallowed by the IRS.  At trial, however, the Second Circuit Court of Appeals reversed the lower court’s holding and allowed an approximation of the expenses based on credible evidence that the expenses were incurred.  In so holding, the Court stated:

“Absolute certainty in such matters is usually impossible and is not necessary; the Board should make as close an approximation as it can, bearing heavily if it chooses upon the taxpayer whose inexactitude is of his own making.  But to allow nothing at all appears to us inconsistent with saying that something was spent.”

This holding gave rise to what today is known as the Cohan Rule (or Cohan Doctrine), which allows a taxpayer who can establish that he incurred a deductible business expense but cannot support the exact amount to claim a deduction for a reasonable estimation of the expense.

But not all expenses are eligible for the Cohan Rule, as taxpayers James Barton recently found out.  Barton, a salesman, deducted $14,741 of unreimbursed business auto expenses and $2,422 of unreimbursed business meals and entertainment expenses on his 2000 return.  The deductions ere based on incomplete mileage logs and year-end credit card summary statements that did not distinguish between business and personal expenses.  Upon audit, the IRS disallowed most of the deductions due to lack of documentation.

Before the Tax Court, Barton acknowledged that he reconstructed many of the records supporting the deductions, years after they were incurred.  In so doing, there were many discrepancies between the records he created and the deductions claimed.

Analyzing the applicable tax laws, the Court first dismissed use of the Cohan Rule as a basis for deducting estimated amounts.  Here, the Court noted that Section 274, enacted after the Cohan decision, includes strict substantiation rules for business expenses claimed for travel, meals, entertainment and listed property, which includes automobiles.  To deduct expenses for these items, taxpayers must substantiate the amount, time and business purpose of the expense, supported with adequate records.  To be adequate, a record generally must be written and must be prepared at or near the time of the expense.  These rules override the Cohan Rule.

Because Barton had reconstructed his records years after he said the expenses were incurred and they did not reconcile with the amounts claimed, he failed to adequately support the deductions.  And because of the nature of the expenses, the Court could not invoke the Cohan Rule to allow deductions for reasonably estimated amounts.  Thus, the Court ruled in favor of the IRS and disallowed Barton’s deductions.

Editor’s Note: The Cohan Rule can be a powerful ally for taxpayers who can support the existence, but not the exact amount, of business deductions.  However, it’s important to remember that certain business expenses, notably those for travel, meals, entertainment and automobiles, are not eligible for the Cohan Rule.  Therefore, it’s imperative that taxpayers maintain proper records supporting these deductions and before claiming these deductions on a return, tax prepares should remind taxpayers of the strict substantiation rules.
