Federal Mileage Reimbursement
GSA changed the automobile rate in the middle of 2026, so the year has two different numbers. Enter your miles and the date travel began to get the rate that actually applies to your voucher, plus what the other 2026 rate would have paid.

|---|---|
| GSA POV mileage reimbursement for official travel: automobile, automobile when a government car was authorized and available, motorcycle, and privately owned airplane. | Per diem for lodging and meals, airfare, and rental cars. Also not modeled: the parking, ferry, bridge, road and tunnel fees that 41 CFR 301-10.302 lets you claim on top of mileage, and the 41 CFR 301-10.303 rule that mileage is payable to only one traveler when two employees share a car. |
| Rate selection by the date travel began, across four published periods: July 1 2026, January 1 2026, 2025, and 2024. | Dates before January 1, 2024. We return no rate rather than guessing. Also not modeled: how your agency splits a voucher for a trip that straddles July 1, 2026. |
| Nautical to statute mile conversion for airplane claims, at the GSA factor of 1.15077945. | Airport-to-airport distance lookup. Use the Department of Transportation inter-airport distance tool GSA links to. |
| The mid-year 2026 comparison, showing what the same trip pays under the other 2026 rate. | Relocation and work-related move mileage, which is a separate $0.235 line from July 1, 2026 under the FTR relocation chapters. |
| A straight miles times rate computation, rounded to the cent. | Tax treatment, accountable-plan substantiation, agency-specific pre-authorization rules, and the constructive-cost comparison some agencies run when POV travel is more expensive than common carrier. |
Totals are rounded to the cent. Your agency travel office approves the voucher and has the final say on which rate and which miles it will pay.
Two rates for one year
Most years the federal mileage rate changes once, on January 1. In 2026 it changed twice. The automobile rate opened the year at $0.725 a mile, then rose to $0.76 on July 1 after the IRS revised its optional standard mileage rates in Announcement 2026-11. The government-car rate moved from $0.205 to $0.235, motorcycles from $0.705 to $0.74, and airplanes from $1.78 to $1.935.
That split is the easiest thing to get wrong on a voucher filed in the autumn for travel that happened in the spring. GSA's instruction is to use the rate in effect when travel began, and it says each published rate stayed in effect until the next date listed. On a 500-mile round trip, picking the wrong 2026 row is a $35 error in one direction or the other.
The government-car question is worth real money
GSA publishes two automobile rates, and the gap between them is the widest it has been in years. If a government-owned automobile was authorized and available and you drove your own car anyway, you are paid $0.235 a mile instead of $0.76, a drop of 69 percent. On a 240-mile round trip that is $56.40 rather than $182.40.
The deciding fact is what your travel authorization says, not what you remember about the motor pool. Read the authorization before you take your own car, and if the authorization is silent, ask the travel office to write down whether a government vehicle was available. Pair this with the Per Diem Lookup to price the whole trip rather than just the driving.
Airplane claims are paid in statute miles
Pilots file in nautical miles and get paid in statute miles. GSA sets the conversion at 1 nautical mile to 1.15077945 statute miles, which turns a 100 nautical mile leg into 115.08 statute miles. At the July 2026 rate of $1.935 that is $222.68 rather than the $193.50 you would claim if you forgot to convert. Convert first, then multiply.
