Standard Mileage Rates for 2013

The 2013 standard mileage rates for use of an automobile are 56.5¢ per mile for business miles driven (an increase of 1¢ from 2012), and 24¢ per mile for medical or moving purposes (up 1¢ from 2012). The rate for rendering gratuitous services to a charitable organization remains unchanged at 14¢ per mile.+

The standard mileage rate for business is based on an annual study of the fixed and variable costs of operating an automobile. The rate for medical and moving expenses is based on variable costs. Taxpayers always have the option of calculating the actual costs of using their vehicle rather than using the standard mileage rate.

A taxpayer may not use the business standard mileage rate for any vehicle after using any depreciation method under the Modified Accelerated Cost Recovery System (MACRS) or claiming a Section 179 deduction for that vehicle, or for more than four vehicles used simultaneously.
