What it means

In the UK, the Personal Allowance is an amount of income that is normally free from Income Tax. If someone's income rises above it, they normally pay Income Tax on the part above the allowance, not on their entire income. The allowance can be reduced for some higher incomes, and other rules can affect whether it applies. It is separate from National Insurance. Its money amount can change, so check the tax year when you see a figure.

Example

Imagine a made-up Personal Allowance of £10,000 and a person earning £15,000. Ignoring all other rules, £10,000 would be free of Income Tax and £5,000 would be considered for Income Tax. This is not a current UK threshold.

Why it matters

It helps explain why two people on different incomes can pay different shares of their income in tax, and why a tax threshold matters even if the stated tax rate stays the same.
