About Oklahoma per diem

GSA has surveyed and listed a non-standard rate for 1 location in Oklahoma, topping out at $116.00 a night in Oklahoma City. Every other city or county in the state defaults to the standard CONUS rate of $110.00 lodging and $68.00 M&IE.

On the first and last day of any trip, M&IE is paid at 75% under the first/last-day rule — $51.00 at the standard rate, or the equivalent 75% figure for whichever listed city you're travelling to. See how to calculate per diem for a business trip for the full worked example.

Frequently asked questions

Does every city in Oklahoma have its own per diem rate?

No — only 1 location has a separately listed GSA rate in Oklahoma. Every other city or county in the state uses the standard CONUS rate of $110.00 lodging + $68.00 M&IE.

How do I calculate per diem for a multi-city trip through Oklahoma?

Use the calculator on each city's page for the nights spent there, then add the totals together — lodging caps and M&IE tiers can differ from one Oklahoma city to the next, so a single flat rate for the whole trip would be inaccurate.
