From the insurance and financial services headquarters in Des Moines to the advanced manufacturing corridors in Cedar Rapids, Iowa is a vital hub for American business and agriculture. For any organization with employees traveling to Iowa, a clear understanding of per diem rates is crucial for efficient and compliant expense management.
Per diem, a daily allowance for lodging, meals, and incidental expenses, is the standard method for handling travel reimbursements. This guide provides a detailed look at the federal per diem rates for Iowa, clarifies important state laws, and shows how you can automate the entire process.
Iowa Per Diem Rate
Per diem rates for official travel in Iowa are set by the U.S. General Services Administration (GSA). These federal rates are mandatory for federal employees and serve as a common benchmark for private sector companies looking to create an IRS-compliant reimbursement policy.
For Fiscal Year 2025 (October 1, 2024, to September 2025), key rates are broken down as follows:
Major Business Centers
Iowa's primary metro areas have their own designated Non-Standard Area (NSA) rates that are higher than the standard U.S. rate.
- Des Moines (Polk County):
- M&IE: $80 per day
- Lodging: A flat rate of $121 per night.
- Cedar Rapids (Linn County):
- M&IE: $74 per day
- Lodging: A flat rate of $118 per night.
The first and last day of travel, the M&IE rate is $60.00 for Des Moines and $55.50 for Cedar Rapids.
Standard CONUS Rate
For any county in Iowa not specifically listed by the GSA—such as Iowa City (Johnson County) or Davenport (Scott County)—the standard CONUS rate applies. For FY 2025, this rate is $178 ($110 for lodging and $68 for M&IE).
