The calculator multiplies the business miles you enter by the IRS business mileage rate for the selected year and period. When the IRS changes the rate during a year, separate mileage inputs are used for each period.
A deduction is not a tax refund
A mileage deduction reduces taxable business income. The estimated deduction shown here is not the amount you receive back as a refund and does not represent your final tax liability.
Only enter business mileage
Enter mileage you have determined is business mileage. Personal driving and ordinary commuting can be treated differently under IRS rules.

It estimates a deduction by multiplying the business miles you enter by the applicable IRS business standard mileage rate for the selected tax year and period.

The IRS business mileage rate changed during 2026, so miles driven from January through June and miles driven from July through December use different rates.
Does the estimated deduction equal my tax refund?
No. A deduction reduces taxable business income. Your actual tax liability or refund depends on your complete tax situation.
What mileage should I enter?
Enter mileage you have determined is business mileage. Personal driving and ordinary commuting can be treated differently under IRS rules.
Does this calculator compare the standard mileage method with actual vehicle expenses?
