Personal Allowance

The amount of income you can earn tax-free each year (£12,570 for 2024/25), reduced if you earn over £100,000.

Key Points

  • ✓Standard allowance is £12,570 for 2024/25
  • ✓Frozen until 2028, causing Fiscal Drag
  • ✓Reduced by £1 for every £2 earned over £100,000
  • ✓Completely withdrawn at £125,140 income
  • ✓Applied automatically through PAYE or Self Assessment

Detailed Explanation

The Personal Allowance is the amount of income you can earn each year without paying Income Tax. For the 2024/25 tax year, most people have a Personal Allowance of £12,570.

This allowance has been frozen since 2021/22 and is scheduled to remain at this level until 2028, which means more people will pay tax as wages increase - a phenomenon known as Fiscal Drag.

Your Personal Allowance is reduced by £1 for every £2 you earn over £100,000. This means if you earn £125,140 or more, your Personal Allowance is reduced to zero.

Some people may receive additional allowances, such as Blind Person's Allowance (£3,070 extra) or the Marriage Allowance (transferring £1,260 to a spouse earning less than the Personal Allowance).

Your Personal Allowance is automatically applied through the PAYE system if you're employed, or you claim it through Self Assessment if you're self-employed.

Practical Examples

  • •If you earn £20,000, you pay no tax on the first £12,570, and 20% Basic Rate Tax on the remaining £7,430 = £1,486 in tax
  • •Someone earning £110,000 loses £5,000 of Personal Allowance (£10,000 over £100k ÷ 2), leaving them with £7,570 Personal Allowance instead of the full £12,570
  • •A married couple where one earns £10,000 and the other earns £30,000 can transfer £1,260 of unused allowance via Marriage Allowance, saving £252 in tax annually
