Why is my tax code 1257L?

If your payslip shows 1257L, you're on the standard UK tax code. This is what most employees see when they have a single job, no taxable benefits in kind, and a normal employment history. Here's what it means line by line.

4-minute read

Tax code 1257L is the standard UK PAYE tax code for 2026/27. The digits 1257 × 10 = £12,570 tax-free Personal Allowance for the year. The L suffix means you get the standard PA with no special adjustments. Most UK employees with a single job and no benefits in kind will be on 1257L.

How 1257L breaks down

The code splits into two parts:

The £12,570 matches the UK Personal Allowance — the amount of income everyone can earn tax-free. It has been frozen at this level since 2021/22 (the “fiscal-drag freeze”) and the current Government has extended the freeze to April 2028.

On a 1257L code, PAYE applies tax as follows in 2026/27:

Income bandTax rate
£0 – £12,5700% (Personal Allowance)
£12,571 – £50,27020% basic rate
£50,271 – £125,14040% higher rate
£125,141+45% additional rate

Worked example — £35,000 salary on 1257L

ComponentAnnualMonthly
Gross salary£35,000£2,917
Personal Allowance applied£12,570£1,048
Taxable income£22,430£1,869
Income tax (20%)−£4,486−£374
Employee National Insurance−£1,794−£150
Take-home£28,720£2,393

Across 12 monthly pay periods, PAYE divides the £12,570 PA into £1,048/month of tax-free pay. Anything above that gets taxed at the appropriate rate.

When you should be on 1257L

You should normally be on 1257L if all the following are true:

Scottish version: S1257LScottish-resident employees on the standard PA see S1257L. The S prefix tells PAYE to apply Scottish income tax bands (six bands from 19% starter to 48% top rate) instead of the UK-wide three-band system. Same £12,570 PA.
Welsh version: C1257LWelsh-resident employees see C1257L. Currently Welsh bands match rUK bands but the Welsh Government has the power to vary them.

When you wouldn't be on 1257L

HMRC adjusts your code away from 1257L when:

What to do if your code is something other than 1257L

Action 1: Check the reasonHMRC sends a P2 coding notice (sometimes called a Notice of Coding) when your code changes. It explains the calculation. Check the HMRC app or your Personal Tax Account at gov.uk/personal-tax-account for the latest P2.
Action 2: Use the tax code decoderThe tax code decoder breaks down what your specific code means and flags any obvious issues.
Action 3: Contact HMRC if it seems wrongPhone 0300 200 3300 with your NI number and last payslip. Most code corrections are resolved within 1-2 pay cycles. The wrong tax already paid is refunded through PAYE — no separate claim needed.
