GSA has reduced the mileage reimbursement rates for federal employees using personal transportation for official business in calendar year 2010. The most widely applied rate, for the use of a privately owned automobile, is dropping from 55 to 50 cents per mile. The rate for a motorcycle is dropping from 52 to 47 cents per mile.
Rates typically are adjusted early in a calendar year to reflect changes in fuel prices and to parallel rates set by the IRS for certain tax purposes.
