How it works

Each line is read as a date, a number of miles and a note. The calculator checks which IRS rate period the date falls in, adds up the miles for each period and multiplies by that period's rate. Lines it cannot read are listed, not silently dropped.

The result text is a tab-separated table you can paste into a spreadsheet or keep with your tax records.

Things to keep in mind

Only 2025 and 2026 rates are loaded. Trips in other years are counted in the miles but not in the dollar total.

If you use the standard mileage rate, you cannot also deduct gas, repairs or depreciation for the same car. Parking and tolls are still deductible on top.

Frequently asked questions

Why does the date of each trip matter in 2026?

The IRS business rate changed on July 1, 2026, from 72.5 to 76 cents a mile. A trip on June 30 and a trip on July 1 are worth different amounts, so the log has to be split by date.

What does the IRS want in a mileage log?

For each business trip: the date, the miles, where you went and why. The total miles for the year and your odometer readings at the start and end help too. Write it at the time of the trip or soon after.

Can I use an estimate instead of a log?

The IRS can disallow a deduction that is not backed by records. Apps and simple spreadsheets both work. This page accepts a paste from either.

What counts as business miles?

Driving between work locations, to clients, to the bank or supplier for the business, and from home to a temporary work site. Commuting from home to your regular workplace does not count.
