Weekly amounts by profit
Income Tax and Class 4 National Insurance for 2026/27 in England, Wales and Northern Ireland, spread over 48 working weeks. Profit is after your expenses or mileage claim.
| Yearly profit | No other income: a week | % of profit | With a £25,000 job: a week | % of profit |
|---|---|---|---|---|
| £10,000 | £0.00 | 0% | £41.67 | 20% |
| £15,000 | £13.16 | 4% | £65.54 | 21% |
| £20,000 | £40.25 | 10% | £92.62 | 22% |
| £25,000 | £67.33 | 13% | £119.70 | 23% |
| £30,000 | £94.41 | 15% | £166.50 | 27% |
| £40,000 | £148.58 | 18% | £262.33 | 31% |
| £50,000 | £202.75 | 19% | £358.16 | 34% |
With no other income, the first £12,570 of profit is tax-free. A job uses that allowance up, so every pound of delivery profit is taxed: see job plus delivery driving. Scotland has different Income Tax bands; the calculator handles them.
Your first January
If your Self Assessment bill is £1,000 or more, HMRC usually asks for payments on account: two advance payments towards next year, each half of this year's bill, due 31 January and 31 July. In the first year that means paying about 150% of the bill in January. The calculator shows this figure under "Your January bill".
Making it easy
- Move the weekly amount into a separate savings account each time the apps pay you.
- Use profit, not earnings: a high-mileage driver's tax is much lower than a percentage of earnings would suggest.
- Recheck when your hours or miles change, and when the tax year changes on 6 April.
- If you also have a job and owe under £3,000, you may be able to pay through your tax code by filing online by 30 December.
Common questions
Is 20% enough to set aside?
It depends. With no other income, 20% of profit is more than you'll owe up to about £50,000. With a job that uses your Personal Allowance, you'll owe about 20% of profit plus up to 6% National Insurance, so 20% can fall short.
Should I set aside a percentage of earnings or profit?
Profit is what you're taxed on: earnings minus your expenses or mileage claim. A percentage of earnings can be far off for high-mileage drivers whose costs are large.
Why is my first tax bill so big?
If the bill is £1,000 or more, HMRC usually adds a payment on account: half of this year's bill again, paid in advance towards next year. So the first January can be about one and a half times the bill.
Can I pay through my tax code instead?
If you have a job and owe less than £3,000, HMRC can collect it through your tax code, as long as you file online by 30 December. Class 2 National Insurance can't be collected this way.
