Frequently asked questions
Does every city in District of Columbia have its own per diem rate?
No — only 1 location has a separately listed GSA rate in District of Columbia. Every other city or county in the state uses the standard CONUS rate of $110.00 lodging + $68.00 M&IE.
How do I calculate per diem for a multi-city trip through District of Columbia?
Use the calculator on each city's page for the nights spent there, then add the totals together — lodging caps and M&IE tiers can differ from one District of Columbia city to the next, so a single flat rate for the whole trip would be inaccurate.
