Effective January 14, the mileage reimbursement rate for federal employees who use privately owned vehicles for official travel will rise from 31 cents to 32.5 cents, largely a reflection of higher gasoline prices. The change parallels the new IRS standard mileage rate for tax deductibility purposes, which rose from 31 to 32.5 cents effective January 1. The reimbursement rates for using personal motorcycles and airplanes for duty purposes, 26 and 88 cents per mile respectively, are staying the same.
