Per Diem for Government Contractors

If you bill travel on a federal contract, your reimbursements are almost always capped at the GSA per diem rate. Contracting officers reject travel claims that exceed the federal limit or lack documentation.

Why the GSA rate is the ceiling

The Federal Travel Regulation (FTR) and Joint Travel Regulations (JTR) set per diem for federal employees, and the Federal Acquisition Regulation (FAR) ties contractor travel reimbursement to those same limits. Bill above them and the excess is unallowable.

Document every trip

• Destination city and exact dates.
• Business purpose tied to the contract.
• Lodging at or below the cap, with the 75% rule applied to travel days.

Build a defensible figure

PerDiemWise produces an itemised, GSA-rate per-diem total you can attach to a travel voucher — the kind of clean, rate-defensible breakdown a contracting officer expects.
