What it does

Built around real CIS work, not a generic timesheet

Postcode-based, calculated automatically

Enter a site postcode once and DayGraft remembers the distance from home for that site every time you log a day there afterwards.

HMRC's current rate, applied correctly

55p per mile for the first 10,000 business miles in the tax year, then 25p after — updated automatically from the rate that changed on 6 April 2026, the first rise since 2011. Earlier tax years correctly keep the old 45p rate.

Multi-site days handled properly

Work two sites in one day and DayGraft works out the real route — home to first site to second site to home — rather than assuming two separate round trips and overstating your claim.

Never shown on your invoice

Mileage is a personal tax deduction, not something a contractor pays you for — DayGraft keeps it entirely separate from your weekly statement, exactly as HMRC intends.

Works in Simple Hours too, with a fix for a common mistake

If you logged weeks of hours before setting up mileage, DayGraft can apply the correct figure to already-logged days without deleting anything — including handling a mileage rate that changed partway through the year.

Questions

Before you download

What mileage rate does DayGraft use?

HMRC's simplified mileage rate: 55p per mile for the first 10,000 business miles in a tax year, then 25p after that. This rose from 45p on 6 April 2026. DayGraft applies whichever rate applied at the time, so figures for earlier tax years are unaffected.

Can I claim mileage for every site I work at?

That depends on your own circumstances. HMRC's simplified rate generally applies to travel to a temporary workplace, not ordinary commuting to a permanent one. DayGraft calculates the distance and the allowance figure, but doesn't judge whether a specific journey qualifies — check with an accountant if you're unsure.

Does it work out mileage automatically, or do I enter it manually?

Automatically, from postcodes. Add your home postcode once in Settings, then a site's postcode the first time you use it — DayGraft calculates the distance and remembers it for next time.

What happens if I work at two sites in one day?

DayGraft detects same-day entries at different sites and works out a sensible total route — home to the first site, to the second, and home again — rather than counting two full round trips and overstating the claim.

Is mileage shown on the statement I send my contractor?

No, and it shouldn't be. Mileage is a personal tax deduction against your own income, not part of what a contractor owes you for the work. DayGraft keeps it out of the statement entirely.

I already logged hours without setting up mileage — can I fix it?

Yes, in Simple Hours. Set the correct mileage figure on the job, and a section appears to apply it to already-logged days — either the whole tax year or from a specific date, and it can be run more than once if your mileage changed partway through the year.
