US Business Vehicle Tax Deduction Calculator
Select the tax year the business miles were driven.
Enter the total miles driven for business purposes during the tax year.
Note: To use the Standard Mileage Rate, you generally must choose this method in the first year the car is used for business. In later years, you can choose either method. You cannot use this method if you use 5 or more cars at the same time, or have claimed Section 179 or accelerated depreciation on the vehicle.
Enter the tax year the expenses were incurred.
Enter the total miles driven for *all* purposes during the year.
Enter the miles driven specifically for business.
Enter your actual vehicle expenses for the year (excluding depreciation).
**Important:** Enter the *deductible* depreciation amount you have calculated separately for the business use of the vehicle. This tool does NOT calculate depreciation due to its complexity (Section 179, Bonus Depreciation, limits, etc.).
Note: Using the Actual Expenses method requires detailed record-keeping of all vehicle expenses and mileage. Depreciation rules are complex; the tool uses the deductible depreciation amount you provide. You generally must use Actual Expenses if you did not elect the Standard Mileage Rate in the first year the vehicle was placed in business service.
This calculator provides estimates based on the data you enter and standard mileage rates. Actual tax outcomes depend on your specific circumstances, eligibility to use each method, and current tax laws. Record-keeping is required for both methods. Consult a qualified tax professional for personalized advice.
