About Mileage Deduction Calculator
Mileage Deduction Calculator applies the official 2026 IRS standard mileage rates, including the mid-year increase, to your business miles and adds parking and tolls for a total deduction estimate.
2026 has two business rates because the IRS raised the rate mid-year under Announcement 2026-11: 72.5 cents per mile for driving from January 1 through June 30, and 76 cents per mile from July 1 through December 31. Enter the miles for each half separately and the calculator applies the right rate to each, then adds deductible business parking and tolls. Keep a mileage log with dates, destinations and business purpose, because the rate depends on when you drove. Calculator results depend on the inputs, units, assumptions, formulas and reference date or rate where applicable. Confirm units and assumptions, compare the result with a known example when possible, and verify current external rates or rules.
Primary objective: Applies the 2026 IRS business mileage rates, split at the July 1 mid-year increase, plus parking and tolls.
Privacy assurance: The calculation is performed locally in the browser from the values you enter.

Frequently Asked Questions
Why are there two rates for 2026?
The IRS set 72.5 cents in December 2025, then raised it to 76 cents effective July 1, 2026 under Announcement 2026-11 as driving costs rose. The rate follows the date you drove, not the date you file.
What else can I add on top of the mileage rate?
Business parking fees and tolls are deductible in addition to the standard rate. Fuel, insurance and repairs are already covered by the rate and are not deducted separately.
Does this cover medical or charitable driving?
No. Medical and moving mileage used 20.5 cents before July and 23.5 cents after; charitable driving stayed at 14 cents. This calculator focuses on the business rate.
What should I check before using the Mileage Deduction Calculator result?
Confirm units and assumptions, compare the result with a known example when possible, and verify current external rates or rules. The result is a mathematical model based on the supplied inputs and assumptions.
Does Mileage Deduction Calculator replace a professional or authoritative source?
No. Mileage Deduction Calculator is a practical utility. Where the result affects a regulated, financial, medical, legal or business decision, verify it against the appropriate authoritative source or qualified professional.
What can affect the result of Mileage Deduction Calculator?
Calculator results depend on the inputs, units, assumptions, formulas and reference date or rate where applicable. Input quality and the selected options can also change the result.
