The IRS mileage reimbursement rate is an optional rate, recommended by the Internal Revenue Service in the U.S., that is used to calculate the deductible costs of operating an automobile for business, medical, charitable, or moving to a new home reasons.

The IRS mileage reimbursement rate is adjusted depending on the IRS-determined cost of operating a motor vehicle.

According to the IRS, the IRS mileage reimbursement 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 purposes is based on the variable costs as determined by the same study. Independent contractor Runzheimer International conducted the study.

Costs of operating an automobile include 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. The charitable rate is set by law.

The IRS mileage reimbursement rates for 2017 are:

  • 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 in 2016, and
  • 14 cents per mile driven in service of charitable organizations, the same as in 2016, by statute.

Self-Employed or People Who Use Their Car for Business

For the self-employed or for employees who use their own vehicles for business-required travel, the IRS mileage reimbursement rate guides tax deductions for the use of a car or truck.

Employers use the IRS mileage reimbursement rate to reimburse employees for business-related use of their personal vehicle. In these instances, employees are generally required to produce receipts and mileage reports.

Taxpayers may not use the IRS mileage reimbursement rate for tax purposes on their income tax return if they have used a depreciation method, for the same vehicle, to account for vehicle use in the past.

Taxpayers have the option to document the actual costs of driving their vehicle or they may use the IRS mileage reimbursement rate for tax purposes. 

For example, a consultant and trainer who drives to client locations or other venues to perform services must track both the location where the service was performed and the number of miles driven round trip.

At the same time, the consultant/trainer is expected to track personal miles traveled using the same vehicle. When tax season arrives, the tax professional needs a business mileage total and a personal mileage total. He or she uses this information to legally adjust taxes paid using the business miles as an allowed business deduction.
