How It Works

Per diem rates are set by the GSA (General Services Administration) and vary by location. The standard CONUS rate is $107/night for lodging and $64/day for meals and incidental expenses (M&IE). First and last travel days typically receive 75% of the M&IE rate. Per diem payments at or below GSA rates are not taxable income. Amounts above GSA rates are taxable.
