The internal revenue service has announced the new mileage reimbursement rate for 2010.  This year the mileage rate will be dropping from fifty five cents per mile in 2009, to fifty cents per mile for the 2010 year.  The change in rate as stated by the IRS is due in part by lower transportation costs as compared to a year ago.
