Your rate drops. The first 10,000 business miles in a tax year are worth 55p each; everything after that is worth 25p.

The threshold is per tax year, not per vehicle and not per platform. It runs 6 April to 5 April and starts again from zero each year. A full-time driver typically passes it somewhere around the autumn.

In money: 10,000 miles at 55p is £5,500 of deduction. The next 10,000 at 25p is £2,500. That is not a reason to stop driving, but it is a reason to know when it happens, because the amount you should be setting aside for tax goes up sharply the day you cross it.

It is also per person, not per vehicle. Using two cars does not give you two allowances.

JoltMile tracks your cumulative business miles across the year and applies the right rate to each shift automatically, including the shift you cross on, which gets split between the two rates.
