To reflect the recent increase in gas prices, the IRS raised the standard mileage rates for the last six months of the year. The rate will increase to 55.5 cents per mile for business miles driven from 7/1/11 through 12/31/11, a 4.5 cent per mile increase from the rate in effect for the first six months of 2011 [see Rev. Proc. 2010-51 (2010-51 IRB 883) ].

 The rate for computing deductible medical or moving expenses will also increase by 4.5 cents per mile to 23.5 cents per mile, up from 19 cents per mile for the first six months of 2011. The rate for providing services for a charity is set by statute, and remains at 14 cents per mile.
