Frequently asked questions
Does every city in Iowa have its own per diem rate?
No — only 2 locations have a separately listed GSA rate in Iowa. Every other city or county in the state uses the standard CONUS rate of $110.00 lodging + $68.00 M&IE.
Which city in Iowa has the highest per diem rate?
Des Moines has the highest listed lodging cap in Iowa, at $121.00 a night, compared with $115.00 in Dallas.
How do I calculate per diem for a multi-city trip through Iowa?
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 Iowa city to the next, so a single flat rate for the whole trip would be inaccurate.
