Income Tax bands 2026/27

These bands apply in England, Wales and Northern Ireland. Scotland has its own five-band system set by the Scottish Parliament. The Personal Allowance is taxed at 0%, and the rates apply only to income above it:

BandTaxable incomeRate
Personal AllowanceUp to £12,5700%
Basic rate£12,571 – £50,27020%
Higher rate£50,271 – £125,14040%
Additional rateOver £125,14045%
The £100k trap: the £12,570 Personal Allowance is cut by £1 for every £2 you earn above £100,000, so it is gone completely at £125,140. That creates an effective 60% marginal rate on income between £100,000 and £125,140. To see how a salary splits across these bands, use the income tax calculator on ukcalculator.com.

National Insurance 2026/27

Employees pay Class 1 National Insurance through PAYE. The main rate is 8% on earnings between the primary threshold and the upper earnings limit, then 2% above:

Earnings band (annual)Employee rate
Up to £12,570 (primary threshold)0%
£12,570 – £50,270 (upper earnings limit)8%
Over £50,2702%

Self-employed workers pay Class 4 NI instead, at 6% on profits between £12,570 and £50,270 and 2% above. Class 2 NI is no longer charged but voluntary contributions still build State Pension entitlement. You can check the National Insurance due on any salary with this National Insurance calculator.
