IRS mileage reimbursement explained

The Internal Revenue Service publishes optional standard mileage rates each year for business, medical, moving, and charitable driving. Employers often use these rates to reimburse employees, and self-employed taxpayers may deduct business miles on Schedule C when they choose the standard mileage method. This calculator applies the 2024 IRS rates and adds parking and tolls separately.

If you are estimating broader self-employment taxes on 1099 income, pair mileage results with the 1099 tax calculator. Business owners tracking vehicle depreciation instead of the per-mile method can review asset value changes with the car depreciation calculator.

Mileage reimbursement formula

Total reimbursement equals distance multiplied by the applicable per-mile rate, plus out-of-pocket parking and tolls:

Total Reimbursement=(Miles×Rate)+Tolls and Parking\text{Total Reimbursement} = (\text{Miles} \times \text{Rate}) + \text{Tolls and Parking}

When comparing reimbursement to actual fuel spend, estimate gallons used and subtract fuel cost:

Net Reimbursement=Total Reimbursement−(MilesMPG×Fuel Price)\text{Net Reimbursement} = \text{Total Reimbursement} - \left(\frac{\text{Miles}}{\text{MPG}} \times \text{Fuel Price}\right)

Worked example: business trip

A 250-mile business trip at the 2024 IRS business rate of $0.67 per mile produces $167.50 in mileage reimbursement. With $20 in tolls, total reimbursement is $187.50. Parking and tolls are added on top of the mileage amount, not included in the per-mile rate.

Frequently asked questions

What is the IRS business mileage rate for 2024?
The IRS standard business mileage rate for 2024 is $0.67 per mile. Medical and moving miles are $0.21 per mile, and charitable miles are $0.14 per mile.
Can I deduct mileage if my employer reimburses me?
If your employer reimburses you at or below the IRS standard rate under an accountable plan, the reimbursement is generally not taxable. You cannot double-deduct the same miles on your personal return.
Are tolls and parking included in the IRS mileage rate?
No. The standard mileage rate covers operating costs such as gas, maintenance, and depreciation. Parking fees and tolls are separately deductible or reimbursable in addition to the per-mile amount.
Should I use standard mileage or actual expenses?
The standard mileage method is simpler because you track only miles driven. Actual expense method requires detailed records for gas, repairs, insurance, and depreciation. You must generally stick with one method per vehicle after the first year.
Does commuting count as business mileage?
Ordinary commuting from home to your regular workplace is not deductible business mileage. Trips between work sites, client visits, and temporary work locations away from your main office may qualify.
