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 for your 2026 return so you can see which produces the larger write-off, and a larger deduction means lower taxable income. The projected 2026 standard business rate of 69.5 cents per mile anchors the comparison.

On the standard side, the tool multiplies your business miles by the 2026 rate of 69.5 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: Freelance Graphic Designer's 2026 Mileage Dilemma

  1. 1 Sarah, a freelance graphic designer, drove 15,000 business miles in 2026. Her actual vehicle expenses for the year were: Fuel: $3,000, Maintenance/Repairs: $800, Insurance: $1,200, Registration: $150, Depreciation: $4,500. Her car loan interest was $750. Her business use percentage was 100%.
  2. 2 Standard Mileage Deduction: 15,000 miles * $0.695/mile = $10,425. 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 = $10,425. Actual Expense Deduction = $10,400.
  4. 4 In this scenario, the Standard Mileage Deduction of $10,425 is slightly larger than the Actual Expense Deduction of $10,400. Sarah should choose the standard mileage method for her 2026 tax filing to maximize her deduction by $25.

Frequently Asked Questions

Should I use the standard mileage rate or actual expenses?
The standard mileage rate (70 cents/mile in 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. You must choose actual expenses in the first year to switch 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.
