Questions

What is the per diem rate in Idaho if my city is not listed?
The standard CONUS rate: $113 a night for lodging and $68 a day for M&IE in FY2027. GSA's file says the standard rate "applies to all counties not specifically listed" and that "cities not listed may be located in a listed county", so check the county first.
When do the FY2028 Idaho rates start?
Federal per diem rates follow the federal fiscal year: FY2028 rates take effect on October 1, 2027. GSA usually publishes them in August or September.
