Understanding the UK PAYE System
Pay As You Earn (PAYE) is the system HM Revenue and Customs (HMRC) uses to collect Income Tax and National Insurance contributions directly from employee wages.
For technology professionals working in London and throughout the United Kingdom, knowing how progressive tax thresholds affect gross salary helps accurately evaluate compensation packages.
HMRC Income Tax Bands for 2026
The tax rates for England, Wales, and Northern Ireland apply across progressive thresholds:
| Band | Taxable Income (£) | Tax Rate |

| Personal Allowance | Up to £12,570 | 0% (Tax-Free) |
| Basic Rate | £12,571 to £50,270 | 20% |
| Higher Rate | £50,271 to £125,140 | 40% |
| Additional Rate | Over £125,140 | 45% |
(Note: If your adjusted net income exceeds £100,000, your Personal Allowance decreases by £1 for every £2 of income above £100,000, reducing to zero at £125,140).
