How do I know what my tax-free personal allowance is?

It’s easy to find out – just check your tax code. If it starts with a number and ends with a letter, replace that letter with the number 0, and you’ve got your tax-free allowance for the year. For example 1257L gives you an annual allowance of £12,570.

If your tax code doesn’t start with a number, then you don’t have a tax-free allowance for this employment.

 These figures are correct for the 2024/25 tax year.
