Per diem is an allowance for lodging, meals, and incidental expenses. The U.S. General Services Administration (GSA) establishes the per diem reimbursement rates that federal agencies use to reimburse their employees for subsistence expenses incurred while on official travel within the continental U.S. (CONUS), which includes the 48 contiguous states and the District of Columbia. The U.S. Department of Defense (DOD) establishes rates for travel in non-foreign areas outside of CONUS, which includes Alaska, Hawaii, and U.S. territories and possessions. The U.S. Department of State establishes rates for travel in foreign areas. For more information on rates established by DOD and the State Department visit travel.dod.mil and aoprals.state.gov .
Please visit www.gsa.gov/perdiem to find the rates. Click on a state on the map to view that state's rates or enter the location in the search box. Even though some cities are listed for your lookup convenience, not all cities can or will be listed. To look up the county a destination is located in, visit the Census Geocoder . If neither the city nor county you are looking for is listed on the GSA per diem rate page, then the standard CONUS rate applies.
Non-standard areas (NSAs) are frequently traveled by the federal community and are reviewed on an annual basis. Standard CONUS locations are less frequently traveled by the federal community and are not specifically listed on our website.
Per diem rates are set based upon contractor-provided average daily rate (ADR) data of local lodging properties. The properties must be fire-safe and have a FEMA ID number. The ADR is a travel industry metric that divides room sales rental revenue by the number of rooms sold. All rates are evaluated to ensure that they are fair and equitable in the GSA and Office of Management and Budget approval process. For more detailed information, visit the Factors Influencing Lodging Rates page.
5 U.S.C § 5702 gives the Administrator of the U.S. General Services Administration (GSA) the authority to establish the system of reimbursing Federal employees for the subsistence expenses (lodging, meals, and incidentals) of official travel. The law governs how GSA sets rates today, and allows the GSA Administrator to establish locality-based allowances for these expenses with a reporting requirement back to Congress. The law was established to protect Federal employees by fairly reimbursing them for travel expenses. In addition, if a Federal employee cannot find a room within the established per diem rates, the travel policy allows the agency to reimburse the actual hotel charges up to 300 percent of the established per diem rates.
The per diem program has several standards that it follows in its systematic structured per diem methodology. The first level is having a "standard rate" that applies to approximately 85 percent of counties in the continental United States.
It is GSA's policy that, if and when a Federal agency, on behalf of its employees, requests that the standard rate is not adequate in a specific area to cover costs of travel as intended by the law, GSA will study the locality to determine whether the locality under study should become a "non-standard area." If the study recommends a change, a change will be implemented as deemed appropriate. GSA has implemented a process to review and update both the standard and non-standard areas annually.
The standard "boundary line" for where non-standard areas apply is generally one county. This is the case for approximately 85 percent of the non-standard rates that GSA sets. However, in some cases, agencies have requested that the rate apply to an area larger than one county, such as a metropolitan area. In a very small number of cases, an agency can and has requested that a rate apply to just a city and not the entire county. In some rural areas, a rate sometimes applies to more than one county due to lack of an adequate data sample to set a rate otherwise.
GSA uses the Federal Information Processing Series (FIPS) code standard for its apply areas. While GSA often uses ZIP codes to select hotel data samples, the apply area is coded by a FIPS code, unless a Federal agency only wants the rate to apply to certain ZIP codes. These codes are managed by the American National Standards Institute (ANSI) to ensure uniform identification of geographic entities through all federal government agencies.
In order for GSA to conduct a "special" review of a non-standard area (NSA) during the current fiscal year, a Federal Agency Travel Manager or an equivalent individual in grade or title must submit a signed letter on agency letterhead or stationery stating that the present per diem rate is inadequate. The request should contain the following information:
- The geographical areas you want us to study, especially ZIP codes.
- The property names (including addresses, ZIP codes, and rates) where your federal travelers stay while on temporary duty travel and those properties (including addresses, ZIP codes, and rates) that will not honor the federal lodging per diem rate.
- The number of times actual expenses were used and/or federal travelers had to use another lodging facility to stay within the maximum allowable lodging per diem rate, which resulted in additional transportation expenses (rental car, taxi) being incurred.
All valid requests postmarked no later than 12/31 will be eligible for this review. All valid requests received after 12/31, but before 4/1 will be evaluated during the following fiscal year's annual review cycle. After all the requirements are submitted, GSA will obtain updated data from our contractor to determine whether a per diem rate should be increased, decreased or remain unchanged. We will conduct no more than one "special" review for a particular NSA annually.
Letters should be sent to: General Services Administration, Office of Government-wide Policy, 1800 F St. NW., Washington, DC 20405. For more direct service, please also scan and email your request (a signed letter on agency letterhead must be attached) to firstname.lastname@example.org.
The procedure and the request deadline are the same as FAQ #6. However, requests received after 3/31 will not be included in the following fiscal year's annual review cycle because the annual review will have already begun.
If a city is not listed, check to ensure that the county within which it is located is also not listed. Visit the Census Geocoder to determine the county a destination is located in. If the city is not listed, but the county is, then the per diem rate is the rate for that entire county. If the city and the county are not listed, then that area receives the standard CONUS location rate.
Hotels are not required to honor the federal per diem rates. It is each property’s business decision whether or not to offer the rate. Hotels also may or may not choose to extend the rate to other individuals, such as government contractors.
Hotels sometimes offer a "GOV" rate, which might be different than the federal per diem rate. If it is higher, you need to receive approval for actual expense prior to travel in order to receive full reimbursement. It is the traveler’s responsibility to know the federal per diem reimbursement rates, and should not assume a GOV rate is the same as the federal per diem rate. See the FTR Chapter 301, Subpart D-Actual Expense and follow your agency's guidelines.
Lodging taxes are not included in the CONUS per diem rate. The Federal Travel Regulation 301-11.27 states that in CONUS, lodging taxes paid by the federal traveler are reimbursable as a miscellaneous travel expense limited to the taxes on reimbursable lodging costs. For foreign areas, lodging taxes have not been removed from the foreign per diem rates established by the Department of State. Separate claims for lodging taxes incurred in foreign areas not allowed. Some states and local governments may exempt federal travelers from the payment of taxes. For more information regarding tax exempt status, travelers should visit the State Tax Forms page.
Yes, the meals and incidental expense (M&IE) rate does include taxes and tips in the rate, so travelers will not be reimbursed separately for those items.
The Federal Travel Regulation Chapter 300, Part 300-3, under Per Diem Allowance, describes incidental expenses as: Fees and tips given to porters, baggage carriers, hotel staff, and staff on ships.
An M&IE study has traditionally been conducted every three to five years. Based upon the recommendations of the Governmentwide Travel Advisory Committee, GSA began reviewing rates every three years starting with rates for FY 2016.
On the first and last travel day, Federal employees are only eligible for 75 percent of the total M&IE rate for their temporary duty travel location (not the official duty station location). For your convenience, the M&IE breakdown page has a table showing the calculated amount for the "First and Last Day of Travel."
For federal employees, the Federal Travel Regulation (FTR) does not make a provision for "mixing and matching" reimbursement rates. The lodging per diem rates are a maximum amount; the traveler only receives actual lodging costs up to that maximum rate. Therefore, there is no "extra" lodging per diem to add to the M&IE rate. Likewise, the M&IE per diem cannot be given up or transferred to lodging costs. See FTR 301-11.100 and 301-11.101 for more information.
For any official temporary travel destination, you must provide a receipt to substantiate your claimed travel expenses for lodging and receipts for any authorized expenses incurred costing over $75, or a reason acceptable to your agency explaining why you are unable to provide the necessary receipt (see Federal Travel Regulation 301-11.25).
You may ask your agency to authorize the actual expense allowance provision. The Federal Travel Regulation (FTR) 301-11.300 through 306 notes that if lodging is not available at your temporary duty location, your agency may authorize or approve the maximum per diem rate of up to 300% of per diem for the location where lodging is obtained. You should also ensure you have checked www.fedrooms.com to confirm there are no rooms available at per diem in the area where you need to travel.
According to the Federal Travel Regulation (FTR), travelers are entitled to 75% of the prescribed meals and incidental expenses for one day travel away from your official station if it is longer than 12 hours. Please see FTR 301-11.101.
GSA establishes per diem rates and related policies for federal travelers on official travel only, and cannot address specific inquiries concerning the payment of contractors. If the contractor is on a federal contract, check with the contracting officer to see what is stated in their contract. Contractors should also check the travel regulations of their company.
GSA establishes per diem rates, along with its policies for federal employees on official travel only. Truck-related questions should be addressed either to the Department of Transportation (www.dot.gov) or the Internal Revenue Service (www.irs.gov).
