Standard mileage rates for 2015. Notice 2014-79 provides that the standard mileage rate for transportation or travel expenses is 57.5¢ per mile for all miles of business use (business standard mileage rate). The standard mileage rate is 23¢ per mile for use of an auto (1) for medical care described in Code Sec. 213; or (2) as part of a move for which the expenses are deductible under Code Sec. 217. The standard mileage rate is 14¢ per mile for use of an auto in rendering gratuitous services to a charitable organization under Code Sec. 170. (Notice 2014-79, Sec. 3)
The mileage allowance deduction replaces separate deductions for lease payments (or depreciation if the car is purchased), maintenance, repairs, tires, gas, oil, insurance and license and registration fees. The taxpayer may, however, still claim separate deductions for parking fees and tolls connected to business driving. (Rev Proc 2010-51, 2010-51 IRB 883.
