What does tax code S1257L mean?
S1257L is the standard code for a Scottish taxpayer: a £12,570 allowance, but Income Tax is charged at the Scottish rates and bands (19% to 48% across six bands) rather than the rest-of-UK rates.

How this was calculated
For the 2026/27 tax year (Scotland) we apply your tax-free Personal Allowance, the Income Tax bands, employee National Insurance, and any student-loan repayment — each traced to a dated gov.uk/HMRC source. A pension contribution comes off before Income Tax (and before National Insurance too, for salary sacrifice). Over £100,000 the Personal Allowance tapers away, which is why the marginal rate jumps to about 60%.

Who has the S1257L code?
People whose main home is in Scotland. HMRC sets the “S” based on your address, not where you work.
Is S1257L the right code for you?
Right if you live in Scotland. The calculator below applies the Scottish bands; National Insurance is the same UK-wide.
