Oklahoma Per Diem Rate
Per diem rates for official travel in Oklahoma are set by the U.S. General Services Administration (GSA). These federal rates are mandatory for federal employees and serve as a common benchmark for private sector companies looking to create an IRS-compliant reimbursement policy.
For Fiscal Year 2025 (October 1, 2024, to September 30, 2025), key rates are broken down as follows:
Major Metro Area
Oklahoma's capital city is the only location in the state with a designated Non-Standard Area (NSA) rate.
- Oklahoma City (Oklahoma County):
- M&IE: $80 per day
- Lodging: A flat rate of $116 per night.
- The first and last day of travel, the M&IE rate is $60.00.
Standard CONUS Rate
For any county in Oklahoma not specifically listed by the GSA—including other major cities like Tulsa (Tulsa County) and Norman (Cleveland County)—the standard CONUS rate applies. For FY 2025, this rate is $178 ($110 for lodging and $68 for M&IE).
