Cohan Rule: A Closer Look at Its Definition and Impact on Tax Deductions

Definition & Meaning

The Cohan Rule is a principle in tax law that allows taxpayers to estimate their travel and entertainment expenses when they lack complete documentation. This rule originated from the case Cohan v. Commissioner, where the court recognized that taxpayers could provide reasonable estimates of their expenses, even if they could not produce exact records. However, the Cohan Rule has been largely replaced by stricter documentation requirements under section 274(d) of the Internal Revenue Code, which mandates that travel and entertainment expenses be substantiated with detailed records.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A small business owner travels for a client meeting but loses the receipt for their hotel stay. They can estimate the cost based on similar hotel rates in the area and include that estimate on their tax return, provided they can show they attempted to document the expense.

Example 2: An employee attends a conference and cannot find their meal receipts. They may use the per diem rates established by the IRS to claim a deduction for meals, as long as they have documentation of the conference attendance. (hypothetical example)
