Frequently asked questions
Does every city in Connecticut have its own per diem rate?
No — only 4 locations have a separately listed GSA rate in Connecticut. Every other city or county in the state uses the standard CONUS rate of $110.00 lodging + $68.00 M&IE.
Which city in Connecticut has the highest per diem rate?
Bridgeport / Danbury has the highest listed lodging cap in Connecticut, at $146.00 a night, compared with $124.00 in New London / Groton.
How do I calculate per diem for a multi-city trip through Connecticut?
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 Connecticut city to the next, so a single flat rate for the whole trip would be inaccurate.
