How It Works

Two methods exist for deducting business vehicle costs: the IRS standard mileage rate and the actual expense method. This tool runs both so you can see which produces the larger write-off, and a larger deduction means lower taxable income. The standard side uses the two 2026 IRS business rates: 72.5 cents a mile for miles driven January through June and 76 cents from July 1, so the calculator asks what share of your business miles fell in the first half.

On the standard side, the tool multiplies your business miles by those rates. On the actual side, it totals the vehicle costs you enter (fuel, insurance, maintenance and repairs, depreciation or lease payments; registration fits under maintenance) and prorates the sum by the share of driving you do for business. Self-employed drivers can deduct the business share of car-loan interest under either method, so it does not change which method wins and the calculator leaves it out.

The method you pick in the first year a car is used for business carries forward. Start with the standard rate and you generally keep the option to switch to actual expenses later; elect actual expenses first, however, and you are locked out of the standard method for that vehicle going forward. Either way, detailed records matter for accuracy and for handling depreciation limits on luxury vehicles.

Example: A Freelance Designer Choosing a Method

  1. 1 Sarah, a freelance graphic designer, drives 15,000 business miles in 2026, half of them by June 30. Her actual vehicle expenses for the year are: Fuel: $3,000, Maintenance/Repairs: $800, Insurance: $1,200, Registration: $150, Depreciation: $4,500. Her car loan interest is $750, and she uses the car 100% for business.
  2. 2 Standard Mileage Deduction: 7,500 miles × $0.725 + 7,500 miles × $0.76 = $5,437.50 + $5,700 = $11,137.50. Actual Expense Deduction: $3,000 (Fuel) + $800 (Maintenance) + $1,200 (Insurance) + $150 (Registration) + $4,500 (Depreciation) = $9,650.
  3. 3 Comparing the two: Standard Mileage Deduction = $11,137.50. Actual Expense Deduction = $9,650. The $750 of loan interest is deductible on top of either, $11,887.50 against $10,400.
  4. 4 In this scenario the standard mileage deduction is $1,487.50 larger, so the standard rate wins. Choosing it in the car's first business year also keeps the option to switch to actual expenses later.

Frequently Asked Questions

Should I use the standard mileage rate or actual expenses?
The standard mileage rate (76 cents/mile since July 2026) is simpler and often better for lower-cost vehicles driven many miles. Actual expenses (gas, insurance, depreciation, repairs, etc.) are better for expensive vehicles or those with high operating costs. Pick the standard rate in the car's first business year if you want the option to switch to actual expenses later.
Can I switch between standard mileage and actual expenses?
If you use the standard mileage rate in the first year, you can switch to actual expenses in a later year. However, if you start with actual expenses and use MACRS depreciation, you can never switch to the standard rate for that vehicle.
What counts as business mileage?
Business mileage includes driving to meet clients, traveling between work locations, running business errands, and going to conferences. Commuting from home to your regular office does not count. If you have a qualified home office, all drives from home to business destinations are deductible.
