How the income tax calculator works

Enter your total annual income — this is your gross earnings before any tax is deducted. The calculator applies the current HMRC income tax bands for the 2025/26 tax year to work out how much tax you owe on each slice of your income.

Your tax code determines your Personal Allowance. The standard code 1257L gives you £12,570 tax-free. If your code is different, the calculator adjusts your allowance accordingly — multiply the number in your tax code by 10 to find your tax-free amount.

Once you hit calculate, you'll see your total tax due, effective tax rate, computed Personal Allowance and take-home pay. Open the band breakdown to see exactly how much of your income falls into each tax band and how much tax is charged on each portion.

If you earn above £100,000 the calculator automatically tapers your Personal Allowance — it reduces by £1 for every £2 above £100,000, reaching zero at £125,140.

What you need to know about UK income tax 2025/26

The UK uses a progressive tax system. You don't pay one flat rate on all your income — each band only applies to the portion of earnings that falls within it. Here are the current thresholds:

  • Personal Allowance (0%): £0 – £12,570 — the amount you earn completely tax-free
  • Basic rate (20%): £12,571 – £50,270 — most taxpayers pay at this rate
  • Higher rate (40%): £50,271 – £125,140 — applies once you cross the higher threshold
  • Additional rate (45%): £125,141+ — the top rate for the highest earners

Personal Allowance tapering: If you earn more than £100,000, your Personal Allowance is reduced by £1 for every £2 of income above £100,000. This creates an effective marginal rate of 60% on income between £100,000 and £125,140 — you lose allowance and pay 40% tax simultaneously.

Scottish rates: If you live in Scotland, different income tax bands and rates apply. Scottish taxpayers have a tax code starting with S. This calculator uses the standard rates for England, Wales and Northern Ireland.
