In a new revenue procedure (Rev. Proc. 2010-51), the Internal Revenue Service announced that the optional mileage allowance for owned or leased automobiles is 51¢ per mile for business travel for 2011. That's 1¢ more than the 50¢ allowance for business mileage during 2010.
In addition, the 2011 rate for using a car to get medical care or in connection with a move that qualifies for the moving expense deduction is 19¢ per mile, 2.5¢ more per mile than the 16.5¢ for 2010. The mileage rate for driving an auto for charitable use during 2011 will remain unchanged at 14¢ per mile.
