IR-2019-215, Dec. 31, 2019

WASHINGTON — The Internal Revenue Service today issued the 2020 optional standard mileage rates used to calculate the deductible costs of operating an automobile for business, charitable, medical or moving purposes.

Beginning on Jan. 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 for business miles driven
• 17 cents per mile driven for medical or moving purposes
• 14 cents per mile driven in service of charitable organizations

The rate for business miles driven decreased one half of a cent for business travel driven and three cents for medical and certain moving expense from the rates for 2019. 

The standard mileage rate for business use is based on an annual study of the fixed and variable costs of operating an automobile. The rate for medical and moving purposes is based on the variable costs.

Taxpayers always have the option of calculating the actual costs of using their vehicle rather than using the standard mileage rates.

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 (PDF).

Notice 2020-05, posted today on IRS.gov, contains the standard mileage rates, the amount a taxpayer must use in calculating reductions to basis for depreciation taken under the business standard mileage rate, and the maximum standard automobile cost that a taxpayer may use in computing the allowance under a fixed and variable rate plan. In addition, for employer-provided vehicles, the Notice provides the maximum fair market value of automobiles first made available to employees for personal use in calendar year 2020 for which employers may use the fleet-average valuation rule in § 1.61-21(d)(5)(v) or the vehicle cents-per-mile valuation rule in § 1.61-21(e).
