Per Diem Rates
Per diem rates—the allowance for lodging (excluding taxes), meals, and related incidental expenses—are regularly reviewed and adjusted according to market conditions. GSA establishes per diem rates for destinations within the continental United States (CONUS). Links to foreign rates, established by the State Department, and non-foreign (other than CONUS) rates, set by the Department of Defense, are provided below the interactive map.
