About this site

MileageRates.com is an independent reference site with one job: state the official mileage and per-kilometre rates accurately, and show exactly where each number comes from.

Why it exists

Mileage rates are a strange corner of the web. The numbers come from a handful of primary documents — an IRS notice, a GOV.UK table, a Department of Finance release, an ATO determination — yet most pages ranking for them are written by companies selling tracking apps, and a surprising share are simply out of date. The UK's May 2026 backdated increase made the problem visible: months later, plenty of well-ranked pages still showed the old 45p rate.

Our answer is narrow and a little boring: publish the rates, link the source document for every figure, stamp each page with the date it was last checked against that source, and update the day a rate changes.

Editorial policy

Primary sources only for figures. Every rate on this site traces to an official government document, named on the page (notice number, instrument number, or the dated GOV.UK table). Commentary from accounting firms or app vendors may inform context, but never a number.

Dated verification. Every page carries a "last verified" date — the most recent day we re-checked its figures against the source, not merely the last day we edited prose.

Corrections are visible. If we get a figure wrong, we correct the page and note the correction rather than silently editing. Spotted an error? Email corrections@mileagerates.com and we'll check it against the source within a few days.

No advice. We explain how the schemes work in general terms. We don't know your situation, and nothing here is tax advice. Where the answer genuinely depends on personal facts, the pages say so and point to the authority or a professional.

How the site is funded

The site may carry advertising and clearly disclosed affiliate links (for example, to mileage-tracking apps). Two rules apply: advertisers never influence the rates or editorial content, and no figure on this site is ever sourced from an advertiser. If a recommendation page exists, it will say plainly how it's compensated.

Update calendar

The predictable windows: the IRS announces mid-to-late December for the following calendar year; Canada's Department of Finance follows in late December or January; the ATO sets its rate ahead of the income year starting 1 July; HMRC's rates historically changed rarely — though 2026 proved they can move mid-year, which is why we re-verify all four jurisdictions monthly rather than annually.
