Frequently asked questions
Does every city in Washington have its own per diem rate?
No — only 9 locations have a separately listed GSA rate in Washington. Every other city or county in the state uses the standard CONUS rate of $110.00 lodging + $68.00 M&IE.
Which city in Washington has the highest per diem rate?
Seattle has the highest listed lodging cap in Washington, at $248.00 a night, compared with $126.00 in Spokane.
How do I calculate per diem for a multi-city trip through Washington?
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 Washington city to the next, so a single flat rate for the whole trip would be inaccurate.
