Per diem allowances for business travel

In the Continental United States (CONUS), multiple federal government agencies, such as the General Services Administration (GSA) establish per diem rates. These rates are separated into ‘lodging’ and ‘meals and incidental expenses (M&IE)’.
Per diem rates for non-foreign, non-contiguous U.S. areas, such as Hawaii and Alaska, are established by the Department of Defense Per Diem, Travel and Transportation Allowance Committee (PDTATAC).
Employers have two options when it comes to per diem allowances:
  1. High-low method: locations deemed ‘high-cost’ are assigned a per diem rate, with all other states taking the ‘low-cost’ rate.
  2. Standard rates: these are different rates for each state and individual location.
The high and low rates are revised and updated before each fiscal year. They currently stand as follows:
  1. High-cost: the full rate is $309 USD, with $74 of that being for incidental expenses and per diem meal allowances
  2. Low-cost: the full rate is $214, with $64 of that being for incidental expenses and per diem meal allowances
The list of high-cost localities is updated yearly. You can check the 2023-2024 special per diem rates on the IRS website. These are some of the newly added locations that qualify for the ‘high-cost’ rate:
  • Los Angeles, California
  • San Diego, California
  • Gulf Breeze, Florida
  • Kennebunk/Kittery/Sanford, Maine
  • Virginia Beach, Virginia
Some locations’ ‘high-cost’ status is seasonal—they’re only considered ‘high-cost’ for certain parts of the year. These seasonal locations include:
  • Sedona, Arizona
  • Boston/Cambridge, Massachusetts
  • Santa Barbara, California
  • Naples, Florida
All locations that are not on the list are considered to be ‘low-cost’ areas and take the ‘low-cost’ rate. The same goes for the seasonal ‘high-cost’ areas—they revert to ‘low-cost’ areas for the rest of the year.

Per diem meals & incidental rates in the U.S.

The other option U.S. employers have is to use the standard rate method for per diem allowances. These are determined by the GSA on a yearly basis, and provide individual lodging and M&IE rates for locations all over the Continental United States.
To find your specific destination, you can look it up on the GSA website. Expenses are separated into lodging and M&IE, and are presented on easy-to-read tables.
For example, a search for Albany, New York shows that the per diem rate for meals and incidental expenses is $69.The M&IE amount is then broken down into a per diem allowance for breakfast, lunch, dinner, and incidental expenses. Per diem incidental expenses allowances are capped at $5, regardless of location.

You also have the option to search standard per diem rates by state. Although the state-wide view does not include a detailed per diem by meal rundown, it can be useful for employees touring multiple cities in the same state. The following image is an example of how a state-wide overview of per diem allowances looks.

Here are some quick shortcuts to popular business travel destinations in the U.S.:
Good to know: On the first and last day of travel, federal travelers will get only 75% of the per diem allowance. This is calculated on the per diem page of each location.
Employees must keep receipts and details like dates and times in order to submit an expense report to the Internal Revenue Service (IRS). This is necessary in the continental U.S. regardless of whether employees use the standard rates or the ‘high-low’ substantiation method.

Final thoughts on managing per diem rates for U.S. business travel

Keeping up with changing per diem allowances is a task in itself, but knowing where to go to find the information you need is essential for corporate business travel. Here’s a quick recap of where to go to find the per diem rates for your desired destination.
  • Go to the GSA website to search for your location if you plan to use the standard per diem method.
  • Find the ‘high-cost’ locations on the IRS website if you plan to use the ‘high-low’ substantiation method.
Per diem allowances for meal expenses can be spent wherever the employee desires; however, it shouldn’t exceed the allotted budget. If a per diem rate goes over the standard or agreed amount it’s considered a taxable benefit to employees.
