Per Diem Rates

Calculation of travel per diem rates within the Federal government is a shared responsibility of three organizations:

• The General Services Administration (GSA) prescribes rates for the Continental U.S. GSA updates the Continental U.S. rates once a year, or as necessary. Normally the rates are updated at the start of the new fiscal year. If a uniformed member or DoD federal civilian has questions regarding the adequacy of per diem rates, please see Per Diem Rate Review under Frequently Asked Questions (FAQs) for appropriate procedures. All non-uniformed and non-DoD federal civilians with questions should email GSA at travel.policy@gsa.gov or go to Contact information for Travel Management Policy.



• The Department of State (DoS) prescribes rates for foreign overseas locations and updates these rates at the beginning of every month. If you are a uniformed member or DoD federal civilian and have questions regarding the adequacy of per diem rates, please see Per Diem Rate Review under Frequently Asked Questions (FAQs) for appropriate procedures. All non-uniformed and non-DoD federal civilians should contact the Office of Allowances at AllowancesO@state.gov / 202-663-1121.



• DTMO prescribes rates for Overseas Non-Foreign areas (e.g., Alaska, Hawaii, Guam, Puerto Rico etc.) at least once a year. The Per Diem Committee adds DoD unique footnotes, DoD Installations, and proportional meal rates to rates published by DoS, GSA and DTMO.
