How to Calculate Your IRS Mileage Deduction

Multiply your eligible business miles by the IRS standard mileage rate. For 2024, the business rate is $0.67 per mile. Select your purpose, enter total miles, and see your deduction and estimated tax savings based on your bracket.

What Miles Are Deductible?

  • Business miles — driving between work locations, client visits, errands for work (not your regular commute)
  • Medical miles — driving to and from medical appointments
  • Charity miles — driving in service of a qualified charitable organization

Your regular commute (home to office) is never deductible, even if you work at multiple locations.

Standard Mileage Rate vs Actual Expenses

The IRS lets you choose between the standard mileage rate or deducting actual vehicle expenses (gas, insurance, repairs, depreciation). The standard rate is simpler — just multiply miles by the rate. Actual expenses require detailed records but may yield a larger deduction for expensive vehicles. You must choose one method for each vehicle.

Mileage Tracking Tips

Keep a mileage log with the date, destination, business purpose, and odometer readings for each trip. Many apps automate this. The IRS requires contemporaneous records — don't try to reconstruct your log at tax time.
