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 IRS business rate of 76 cents per mile, in force since July 1, 2026; miles driven from January through June 2026 were deductible at 72.5 cents.

On the standard side, the tool multiplies your business miles by 76 cents per mile. On the actual side, it totals your real vehicle costs, depreciation or lease payments, fuel, oil, repairs, insurance, registration fees, and car loan interest, then prorates that sum by the share of driving you do for business.

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, expects to drive 15,000 business miles in the 12 months from July 2026. Her actual vehicle expenses for that 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: 15,000 miles * $0.76/mile = $11,400. Actual Expense Deduction: $3,000 (Fuel) + $800 (Maintenance) + $1,200 (Insurance) + $150 (Registration) + $4,500 (Depreciation) + $750 (Interest) = $10,400.
  3. 3 Comparing the two: Standard Mileage Deduction = $11,400. Actual Expense Deduction = $10,400.
  4. 4 In this scenario, the Standard Mileage Deduction of $11,400 is $1,000 larger than the Actual Expense Deduction of $10,400, 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.
