Federal Mileage Rate

What Is the Federal Mileage Rate?

The federal mileage rate is the amount of money an employee can deduct from their federal income taxes for the costs of operating a personal car, van, pickup, or panel truck for qualified business, charitable, medical, or moving purposes. The Internal Revenue Service (IRS) determines this rate every year, adjusting for inflation and other variables involved in owning and operating a vehicle. Such variables include:

Are Companies Required to Pay Mileage?

While the practice of reimbursing employees for the miles they drive in their personal vehicle on behalf of work is standard practice, it is not required by law for companies to do so.

However, there are four legal requirements to follow when offering mileage reimbursement:

  1. Mileage reimbursements must be made only for deductible business expenses, such as business travel.
  2. Claims must be supported by employer records that include details such as the time, place, and purpose of travel.
  3. The employee must return any excess reimbursement to the employer.
  4. Employers may choose to reimburse employees at a rate lower than the federal mileage standard. However, the rate must be high enough to cover expenses so that personal vehicle use doesn’t drop an employee’s wages below minimum wage.

How Is Federal Mileage Reimbursement Calculated?

To calculate the mileage reimbursement amount due to an employee, multiply the number of qualified miles by the applicable rate.


On three different occasions, Gunther used their personal vehicle to pick up supplies for their coffee shop. The distance traveled each time was 13 miles. Therefore:

13 miles X 3 trips = 39 total miles

39 miles X ¢58.5 per mile = $22.82 to be reimbursed to Gunther

Does the IRS Require Odometer Readings for Federal Mileage?

Employers can require employees to provide odometer readings for each trip. However, the IRS does not require separate odometer records for each business trip to qualify for federal mileage reimbursement.
