The IRS announced changes to the standard business mileage rates for calendar year 2009. The standard business mileage reimbursement rate is decreasing from 58.5 cents to 55 cents per mile. The standard rate for moving expenses also decreases from 27 to 24 cents per mile.
Business mileage incurred in 2008, but not reimbursed until 2009 should still be reimbursed at the 2008 mileage rate. The Employee Expense Worksheet (UM1612) accommodates changes in mileage rates.
