Summary

Employees on official government work can be paid a per-mile rate when they use their own car, airplane, or motorcycle instead of claiming actual travel costs. The Administrator of General Services sets that rate. If the Internal Revenue Service puts out a single standard mileage rate for taxpayers in a year, the government must use the IRS rate. Using a private vehicle usually must be approved as better for the government, but no special approval is needed if payment is limited to what travel would cost by common carrier (including per diem). If an employee picks a private vehicle over an available government vehicle, the mileage pay is limited to the cost of using the government vehicle. In addition to the per-mile payment, the government can also repay parking, ferry, bridge/road/tunnel tolls, and airplane landing and tie-down fees.
