Mileage for taxes

Business mileage rates and rules for the US, the UK and Canada, with links to the official pages. Updated for 2026.

We make Milepost, an iPhone app that logs gas and work trips. We wrote these up while building its mileage feature, since we had to get every rate right anyway.

None of this is tax advice. If real money rides on it, ask a tax professional.
