What tax code Scottish tax codes (S) actually means
An S at the front of your code means Scottish rates: six bands from 19% to 48% in 2025/26.
An S prefix — S1257L, SBR, SD0 — means you're a Scottish taxpayer, and your income tax uses Scotland's six bands instead of the UK's three: 19% (Starter), 20% (Basic), 21% (Intermediate), 42% (Higher, from £43,662), 45% (Advanced, from £75,000) and 48% (Top, above £125,140). Your £12,570 personal allowance is the same, and so is National Insurance. On £45,000, a Scottish taxpayer pays £6,913.80 — £427.80 more than in England.

What does Scottish tax codes (S) mean?
Income tax on earnings is devolved to the Scottish Parliament, and the S prefix is how PAYE knows to apply Scottish rates. What counts is where you live — a Glasgow resident commuting to a Carlisle employer is a Scottish taxpayer; the reverse is not.
Scotland's 2025/26 structure has six bands above the shared £12,570 allowance: the 19% Starter rate to £15,397, 20% Basic to £27,491, 21% Intermediate to £43,662, then a sharp step to 42% Higher, 45% Advanced above £75,000, and the 48% Top rate above £125,140. The practical headline is the early higher rate: 42% starts at £43,662, nearly £7,000 before England's 40% does.
Below about £29,000 Scottish taxpayers actually pay slightly less than the rest of the UK — the Starter rate saves up to £28 a year. Above £43,662 the gap flips and grows quickly. National Insurance, savings and dividend tax all stay on UK-wide rules regardless of the S prefix.

- Special codes get the prefix too: SBR (20% flat), SD0 (higher flat), SD1, SD2, S0T.
- SK codes exist for Scottish taxpayers with negative allowances.
