Can I use Google Maps Timeline as a mileage log for taxes?

Q: Can I use Google Maps Timeline as a mileage log for taxes?

You can mine Google Maps Timeline for evidence of your drives, but by itself it is not a compliant mileage log: it has no business-versus-personal split, no purpose notes, gaps where tracking was off, and distances that are estimates. It works as a backup source for rebuilding a log — expect hours of manual work — not as the log itself.

Why people try it

Tax time arrives, there's no mileage log, and the one place that might know where you drove all year is Google. Timeline (the feature that used to be called Location History) quietly records visits and routes for many Android and iPhone users, so it feels like a ready-made log.

It's a reasonable instinct — Timeline genuinely is evidence of where you were. The problem is the gap between "evidence" and "log."

What a tax authority actually wants

The IRS (and the CRA in Canada) expect a record kept at or near the time of driving, showing the date, distance, destination, and business purpose of each trip, plus a business-versus-total-miles picture for the year. Records reconstructed months later from memory or raw location data are treated with suspicion and are regularly rejected in audits.

Timeline fails those requirements on its own: it doesn't know which drives were business, records no purpose, shows estimated routes rather than odometer distances, and has holes wherever your phone was off, out of battery, or had tracking paused.

The 2024 change that made this harder

Google moved Timeline storage onto your device in 2024 and retired the web version. That was good for privacy, but it broke most of the third-party services that used to convert a Timeline export into a mileage report, and it means your history can be lost with the phone unless you enabled encrypted backups.

You can still export your own data from Timeline settings in the Google Maps app (the exact menu shifts between versions). What you get is a raw data file of visits and routes — not a report. Turning three months of it into a usable log is an evening of work; a year can take much longer, and you'll still be guessing at the business purpose of each trip from memory.

How to actually use Timeline if it's all you have

If this tax year is already gone and Timeline is your only record: export the data, go month by month, and cross-reference each work-looking drive against something that proves purpose — invoices, job addresses, texts with customers, supplier receipts. Write the reconstructed log up with dates, destinations, distances, and purposes, and keep the corroborating documents together with it. A reconstruction supported by business records is far stronger than a reconstruction from memory alone.

Then fix the coming year so you never do this again: keep a contemporaneous log as you go. That can be a notebook on the dash, a mileage app, or an automatic tracker — the only method that survives a busy season is one that doesn't depend on you remembering anything.

FAQ

Will the IRS accept Google Timeline screenshots in an audit?

Timeline data can support your case as corroborating evidence, but it is not a mileage log by itself — it lacks business purpose and business/personal classification, and its distances are estimates. Auditors look for a contemporaneous log; Timeline plus invoices and job records is a fallback, not a substitute.

Can I still export my Timeline data?

Yes — since Google moved Timeline on-device in 2024 you export from the Google Maps app on your phone rather than from a website. The export is a raw data file of visits and routes that you'll need to process yourself; most older web-based converter tools no longer work with it.

What should I use going forward instead?

Anything contemporaneous beats everything reconstructed. An automatic tracker that records drives as they happen — with a same-week review to mark what's business — meets the timeliness expectation with the least discipline required. TradesTimer does this on-device for free, and pairs each drive with the jobsite time around it.
