Can you claim business mileage with Google Maps History?

Yes — Google Maps History/Timeline can be useful evidence for a business mileage claim, but it’s usually best treated as supporting documentation rather than the only proof.

What you generally want to be able to show is:

• the date of the trip
• the start and end locations
• the distance or mileage
• the business purpose of the trip

Google Maps history can help establish where you went, and it may help you rebuild a mileage log if you didn’t keep one at the time. But by itself it often won’t show the business reason for the journey, so it’s a good idea to pair it with other records such as calendar entries, emails, invoices, or meeting notes.

Practical tips:

• Review your Google Maps Timeline/history and match trips to other business records.
• Add the missing details to a mileage log.
• Keep the log as close to the trip date as possible, because contemporaneous records are usually stronger than a reconstruction done much later.

The exact rules vary by country and can change by tax year, so check the official guidance for your tax authority. If the claim matters for your return, it’s also wise to confirm with a tax professional.
