Mileage deduction calculator

Estimate your business mileage deduction using the IRS standard mileage rate. Pick the period your miles were driven in, since the 2026 rate changed on July 1.

Only miles driven for work: client visits, deliveries, job sites. Not your regular commute.

The IRS raised the 2026 rate from July 1. Miles from both halves of 2026? Run each half separately and add them.

The IRS expects a written log: date, places, miles and purpose for each trip. Milebook keeps that log and totals your business miles at tax time.

Current IRS standard mileage rates (business)

2026: 72.5¢ a mile from January 1 to June 30, and 76¢ a mile from July 1. 2025: 70¢. 2024: 67¢. Source: irs.gov, Standard mileage rates.

Which miles count

Driving for work counts: visiting clients, going between job sites, deliveries, and trips to pick up supplies. Your regular commute from home to a main workplace generally does not. Your tax preparer can confirm what applies to you.

Keep a log

The IRS expects a record made at or near the time of each trip: the date, where you went, the business purpose and the miles. A log rebuilt from memory at tax time is easy to challenge.

Questions

Is this tax advice?

No. It's an estimate at the published standard rate. Whether you can use the standard rate, and which miles qualify, is a question for your tax preparer.

Can I deduct gas as well as mileage?

Not with the standard mileage rate: it already covers gas, maintenance, insurance and depreciation. Parking fees and tolls for business trips can usually be deducted on top.

Why are there two 2026 rates?

The IRS raised the business rate mid-year, from 72.5¢ to 76¢ for miles driven from July 1, 2026. Calculate each half separately.
