Beginning on January 1, 2020, the standard mileage rates for the use of a car (also vans, pickups or panel trucks) will be:
- 57.5 cents per mile driven for business use, down one half of a cent from the rate for 2019,
- 17 cents per mile driven for medical or moving purposes, down three cents from the rate for 2019, and
- 14 cents per mile driven in service of charitable organizations.
A taxpayer may not use the business standard mileage rate for a vehicle after using any depreciation method under the Modified Accelerated Cost Recovery System (MACRS) or after claiming a Section 179 deduction for that vehicle. In addition, the business standard mileage rate cannot be used for more than five vehicles used simultaneously. These and other limitations are described in section 4.05 of Rev. Proc. 2019-46.
