Beginning on Jan. 1, 2017, the standard mileage rates for the use of a car, van, pickup or panel truck will be:
- 53.5 cents per mile for business miles driven, down from 54 cents in 2016
- 17 cents per mile driven for medical or moving purposes, down from 19 cents for 2016
- 14 cents per mile driven in service of charitable organizations
The business mileage rate decreased half a cent per mile and the medical and moving expense rates each dropped 2 cents per mile from 2016. The charitable rate is set by statute and remains unchanged.
For self-employed business owners, interest expense paid on the car loan is also deductible, above and beyond the standard mileage rate.
Parking and tolls are always separately deductible.
The standard mileage rate for business is based on an annual study of the fixed and variable costs of operating an automobile, including depreciation, insurance, repairs, tires, maintenance, gas and oil. The rate for medical and moving purposes is based on the variable costs, such as gas and oil.
