Simplified mileage expenses for a self-employed car, van or motorcycle — enter your business miles for the year and see the deduction, cited to gov.uk, update as you type.
HMRC raised this from 45p — you may be owed the difference
The car and van rate for the first 10,000 miles was 45p a mile for years. HMRC raised it on 17 June 2026, backdated to 6 April 2026 — if your app, spreadsheet or old invoices still say 45p, you're owed the difference on every business mile driven since 6 April.
Already logged Q1 at 45p? No manual redo needed — cumulative quarterly updates self-correct: each quarter's cumulative figure is recalculated from the year's total miles at the current rate, so the shortfall catches up automatically next quarter.
The trap: once you use the flat mileage rate for a vehicle, you're locked into flat-rate mileage for that same vehicle for as long as you keep it in the business — you can't switch that one vehicle to claiming its actual running costs later.
