How the UK PAYE & National Insurance System Works (2025/2026)

In the United Kingdom, employment earnings are taxed through HM Revenue & Customs (HMRC) Pay As You Earn (PAYE) system. Tax and National Insurance contributions (NICs) are automatically deducted by your employer each pay period before paying net wages.

UK taxpayers benefit from a tax-free Personal Allowance of £12,570. Income above this allowance is taxed across progressive bands: Basic Rate (20%), Higher Rate (40%), and Additional Rate (45%). For earnings above £100,000, the Personal Allowance is reduced by £1 for every £2 earned, tapering to zero at £125,140.
