Income Tax Calculator UK 2026/27
England, Wales and Northern Ireland rates. Scotland sets its own bands. Pension is taken off before tax is worked out. National Insurance is not included here — see the Take Home Pay Calculator for the full picture.
Income tax bands 2026/27
| Band | Income | Rate | Tax on a full band |
|---|---|---|---|
| Personal allowance | Up to £12,570 | 0% | £0 |
| Basic rate | £12,571 – £50,270 | 20% | £7,540 |
| Higher rate | £50,271 – £125,140 | 40% | £29,948 |
| Additional rate | Over £125,140 | 45% | No limit |
Each rate applies only to the slice of income inside that band. Earning £51,000 does not mean 40% tax on the whole £51,000 — only on the £730 above £50,270.
The £100,000 trap
Above £100,000, your personal allowance falls by £1 for every £2 of extra income, and is gone entirely at £125,140. Between those two figures your effective marginal rate is 60% — 40% tax plus the lost allowance. Pension contributions and Gift Aid can bring your income back below £100,000 for this purpose.
What changed in the Autumn Budget 2026?
The Budget on 28 October 2026 kept the headline income tax rates and thresholds frozen — the personal allowance and higher-rate threshold stay frozen until April 2031. From 6 April 2027, tax on savings interest rises to 24%, 44% and 49% (from 20%, 40% and 45%), and rental profits are taxed at the same higher rates. Those changes do not affect tax on employment income.
