Reading the table
How Idaho rates work
- Not listed? GSA sets most rates by county. A town in a listed county takes that county's rate; anywhere else in Idaho gets the standard rate of $113 lodging and $68 M&IE.
- Seasons: every destination's lodging rate changes during the year. A trip across a season change has nights at each rate. M&IE stays the same all year.
- First and last days: a federal traveler gets 75% of the M&IE rate on the first and last day of a trip, shown in the last column.
- Lodging rates exclude taxes. M&IE includes taxes and tips on meals.
