The federal per diem rates are used in place of actual expense receipts for substantiation of business travel, but remember that with either substantiation method employees must keep records to prove the time, place, and business purpose of their travel as well as mileage.  If expense reimbursements to employees or contractors are not substantiated, such payments do not qualify as tax-exempt reimbursements and instead must be included, and reported on Forms W-2 (if an employee) or 1099 (if an independent contractor), as part of the gross income paid.
