Your tax code tells your employer how your pay should be taxed through PAYE. Crucially, it tells them what tax-free Personal Allowance you qualify for. A good example of this is the 1263L tax code.

A 1263L tax code tells your employer that you’ve got a slightly higher Personal Allowance than most people. In real terms, it means you’re able to earn a little more in each tax year before you start to pay Income Tax.

To find out how much you can earn tax-free each year, check the number at the start of your tax code and multiply it by 10. For example, tax code 1263L means you can earn £12,630 before you start being taxed. That’s £60 higher than the standard UK tax code of 1257L.
