The IRS audited tax return of a man who had substantial winnings at the horse track, but also claimed offsetting expenses for the many bets he had placed during the year.
During the audit, IRS agent asked for receipts, so the man said he would bring them.
At the next appointment, he presented receipts sufficient to wipe out taxable gains from his winnings. The agent asked a more senior agent for assistance. The senior agent said, "Turn the receipts over."
The backside of all the receipts were covered in dusty footprints.

Cohan v. Commissioner stands for the wonderful proposition that in an IRS audit, even if you don’t have receipts, you might still qualify for a tax deduction.

"The court was harsh on some points, but cut Villa some slack on his undocumented cost of goods sold. The court said that if a taxpayer clearly shows that he incurred a deductible expense but is unable to substantiate the exact amount, the Cohan rule permits the court to estimate it, provided there is a reasonable basis for making such an estimate. In making an estimate, the court takes into account that the fact that the taxpayer’s lack of proper records created the situation."
I'm not a tax professional and can't give tax advice.
But I can relate a good yarn I heard somewhere.
