If you drive to gigs, mileage is probably the biggest allowance in your records. Gigflow now uses the HMRC mileage rate of 55p a mile for the first 10,000 business miles in a tax year, starting from 6 April 2026. After 10,000 miles it is 25p.
That leaves a wrinkle for anyone with gigs either side of the date. A wedding in March and a wedding in May sit in different tax years and need different rates. Working that out by hand in a spreadsheet is where mistakes creep in.
What’s new
55p from 6 April 2026. Gigs dated on or after 6 April 2026 are worked out at 55p a mile for the first 10,000 business miles of the tax year, then 25p.
45p for earlier gigs. Gigs dated from 6 April 2011 to 5 April 2026 are worked out at 45p for the first 10,000 miles, then 25p.
The rate follows the gig date. Each gig looks up the rate for the day you played it. Nothing is set by hand.
How it works
You do not need to change anything. Add a gig with a venue and Gigflow works out the allowance using the rate for that date. Take a 100 mile round trip to a wedding venue, in a year where you are under 10,000 miles. Played on 28 March 2026, the drive is worth £45.00. Played on 11 April 2026, the same drive is worth £55.00.
Open the Mileage page and tap How this is calculated to see the miles and rates behind your total for the tax year.
Why it matters
An extra 10p a mile is real money over a season of late-night drives. The older gigs matter just as much, because a 2025/26 gig worked out at the newer rate would be wrong. Keeping each gig on the rate for its own date means your mileage records hold up whichever tax year you are looking at.
