A mileage log that would hold up if you were asked for it.

1. Year and odometer

Employee? Claim reimbursement from your employer

Since 2018 employees cannot deduct unreimbursed mileage on a federal return, so the useful document is a claim to your employer. It lists your business trips for a date range at your employer's per-mile rate (leave blank for the IRS rate on each trip's date) and downloads as a printable HTML page.

Your most frequent deductible routes. One tap fills the form for today; add the odometer or confirm the miles, then save.

2. Add a trip

Save trip Start GPS tracking

Business, medical and charity trips need a destination and a purpose. GPS tracking only works while this page is open and the screen is on; it fills in the miles when you stop.

The model, and what it leaves out

• Deduction is each trip's miles times the IRS standard rate for the trip's date and category. Business, medical and charity trips are deductible at their rate; commuting and personal trips are not. Tolls and parking on business trips are shown separately because they are deductible in addition to the standard rate.
• Odometer readings take priority over typed miles when both are present and the end is higher than the start.
• Audit-readiness checks look at the log itself: deductible trips missing a purpose or destination, odometer readings that contradict each other, possible duplicates, a log made mostly of round numbers, entries typed long after the trip, and business miles that exceed the year's total.
• Not modelled: whether the standard rate is available for your vehicle, the actual-expense method (see the mileage method calculator), state rules, employee reimbursement plans, and whether a particular trip is deductible at all.

Common questions

What does the IRS expect a mileage log to show?

For each business trip: the date, the miles, where you went and the business purpose, plus the odometer readings at the start and end of the year to prove the total. The IRS calls this adequate records or sufficient evidence, and a log written at or near the time of the trip carries the most weight.

Which rate does it use?

The IRS standard mileage rate for the date of each trip: 70 cents for 2025 business miles, 72.5 cents for January to June 2026 and 76 cents from July 1, 2026. Medical and charity rates are included and every rate can be overridden in the settings. Check irs.gov before you file.

Does it track my location in the background?

No. GPS tracking works only while this page is open and the screen stays on, and it only starts when you press Start. Nothing is uploaded: positions are used to add up the distance in your browser and are not stored. For unattended tracking a native app is still better; this tool is for a log you control.

Where is my data kept, and can I lose it?

In your browser on this device. Clearing site data, or a browser that clears storage for sites you have not opened in a while, removes it. Use Download backup regularly; the file restores on any device.

Can I use it offline?

Yes. Once the page has loaded it works with no signal, and you can add it to your home screen.

Is this tax advice?

No. It applies published rates to the trips you enter and checks your log for gaps. It does not decide whether a trip is deductible, whether the standard rate is available for your vehicle, or how to file.
