Rather than keeping track of the actual cost of operating a vehicle, employees and self-employed taxpayers can use a standard mileage rate to compute their deduction related to using a vehicle for business. But you might also be able to deduct miles driven for other purposes, including medical, moving and charitable purposes.
What are the deduction rates?
The rates vary depending on the purpose and the year:
Business: 54 cents (2016), 53.5 cents (2017)
Medical: 19 cents (2016), 17 cents (2017)
Moving: 19 cents (2016), 17 cents (2017)
Charitable: 14 cents (2016 and 2017)
The business standard mileage rate is considerably higher than the medical, moving and charitable rates because the business rate contains a depreciation component. No depreciation is allowed for the medical, moving or charitable use of a vehicle.
