Idaho per diem rates
Federal fiscal year 2026 · GSA CONUS
Federal travelers and contractors use General Services Administration (GSA) per diem rates to estimate allowable lodging and meals & incidental expenses (M&IE) while on official travel in Idaho. GSA publishes a standard CONUS rate for much of the state and separate, often higher, caps for designated high-cost localities.
This page summarizes published GSA data for FY 2026. For trip-specific totals (travel-day rules, meal deductions, and seasonal lodging by month), use the CONUS calculator with ID pre-selected.
