Mileage reimbursement 2026: Mileage Rate Series

Every row is a verbatim sentence read from the named source's own page through our fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).

2 of the 7 named sources that could be read published a usable figure; 5 published none and are recorded as not published, never filled in; 0 could not be read (blocked, dead or unreachable) and count nowhere.

The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in USD (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 8 candidate sentence(s) were refused by a reviewer with the reason recorded.

The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): one row per rate period per purpose per country - the IRS business, medical/moving and charitable rates, HMRC's approved mileage allowance payments, and the equivalent per-kilometre allowance elsewhere - with its effective FROM and TO date, so a claim dated in the middle of 2026 resolves to the right half-year.

No authority publishes the run: the IRS states the current rate and archives the notices, and 2026 has TWO business rates because the rate moved mid-year on 1 July, which is the single most common way a reimbursement is computed wrong.

Across the series we derive the year-on-year change, the real-terms change against the fuel price series, and the gap between the statutory rate and what an employer actually pays.

8 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
