Understanding Tax Code 1257L (2026/27)
Tax code 1257L is the most common tax code in the UK for employees having one job or pension. Here is exactly how it impacts your take-home pay.
What Does 1257L Mean?
The numbers in your tax code tell your employer or pension provider how much tax-free income you are entitled to in that tax year. For 1257L, multiplying 1257 by 10 gives £12,570. This is the standard Personal Allowance for the 2026/27 tax year.
The letter 'L' indicates that you are entitled to the standard tax-free Personal Allowance.
How Your Taxable Pay is Calculated
If your annual salary is £35,000 and your tax code is 1257L, your employer will subtract £12,570 before calculating your Income Tax. You will only pay tax on the remaining £22,430.
