Receipts are generally required for lodging and for any individual expense of at least 75 dollars when filing a claim for payment in U.S. government travel/expense contexts.
Key receipt rule
For official travel or expense reimbursement, the true statement is that receipts are mandatory for all lodging charges and for each separate expense of 75 dollars or more.
Receipts must be itemized, legible, show that payment was made, and match the amount claimed on the voucher.
