Estimate only, not tax advice. The deduction lowers your taxable profit; how much tax it saves depends on your whole return.

How the calculation works

The standard mileage method is miles × rate. For 2026 the IRS set two business rates, so the calculator works out each half of the year on its own and adds them:

January 1 – June 30, 2026: 72.5 cents a mile (IRS Notice 2026-10, news release IR-2025-128).
July 1 – December 31, 2026: 76 cents a mile (Announcement 2026-11, news release IR-2026-29).

Example: 4,000 miles in each half is 4,000 × $0.725 = $2,900 plus 4,000 × $0.76 = $3,040, a $5,940 deduction. Parking and tolls for business trips are added on top, because the mileage rate does not cover them.

The "rough tax saved" line multiplies the deduction by your income tax bracket plus self-employment tax (15.3% on 92.35% of profit). It ignores the Social Security wage cap, state tax and everything else on your return, so treat it as a ballpark.

Standard rate or actual expenses?

Instead of the standard rate you can deduct the business share of what the vehicle actually cost: gas, repairs, insurance, registration and depreciation. That takes more records and has its own rules, including restrictions on switching methods for a vehicle you have used before. If you use the standard rate in the first year a vehicle is used for business, you can generally choose either method in later years. Rules vary by vehicle; the IRS standard mileage rates page and Publication 463 have the details.

Questions

What is the IRS mileage rate for 2026?

For business driving, 72.5 cents a mile from January 1 to June 30, 2026, and 76 cents a mile from July 1 to December 31, 2026. The IRS raised the rate mid-year because of higher fuel prices.

Which rate do I use for a trip in July?

The rate for the date you drove. Miles driven on or after July 1, 2026 use 76 cents; miles before that use 72.5 cents. That is why the calculator asks for the two halves of the year separately.

Can I deduct gas and repairs as well as the mileage rate?

No. The standard rate already covers gas, oil, repairs, insurance and depreciation. Business parking fees and tolls are the exception: you can deduct those on top.

Does driving from home to my first job count?

If your home is your principal place of business, trips from home to job sites are usually business miles. If you work from a shop or office, the drive from home to that shop is commuting and does not count. When in doubt, ask a tax professional.

What records do I need?

For each business trip: the date, where you went, the business purpose and the miles. Keep the log as you go; a log rebuilt at tax time from memory is the kind the IRS questions.
