When does the Scottish prefix help vs hurt?

Scottish Income Tax is LOWER than rUK below about £33,493 of salary (the 19% starter band saves up to £39.67) and HIGHER above it (the 21% intermediate rate from £29,527 and the earlier 42% threshold). At £20,000 a Scottish taxpayer pays £39.67 less than rUK; at £50,000, £1,496 more; at £100,000, £3,300 more.

Does the S prefix apply to all my income?

Only to non-savings, non-dividend income (salary, pension, self-employment profits). Savings interest is taxed at the UK-wide rates regardless of S prefix. Dividends are taxed at the UK-wide dividend rates. Capital Gains is fully UK-wide - no Scottish Capital Gains Tax (CGT).

I work in England but live in Scotland - which rules apply?

Scottish rules. Your residence determines Scottish-taxpayer status, NOT your employer's location. A worker living in Edinburgh and commuting to a London office pays Scottish Income Tax at S-prefix rates via PAYE.

Why does my SBR code exist?

SBR is the Scottish-prefix variant of the BR code (Basic Rate - 20% on everything). Used for second jobs or pensions where the primary PA is already used elsewhere. SD0 = Scottish intermediate rate (21% flat), SD1 = Scottish higher rate (42% flat), SD2 = Scottish advanced rate (45% flat), SD3 = Scottish top rate (48% flat).

S Tax Code Prefix: Scottish Taxpayer 2026/27

The S prefix (e.g. S1257L, SBR, SD0) tells PAYE you are a Scottish taxpayer. Income Tax follows Scotland's 6-band system: 19% starter, 20% basic, 21% intermediate, 42% higher, 45% advanced, 48% top.

What the S prefix tax code means

An S prefix is added to any tax code when HMRC has determined that you are a Scottish taxpayer for the tax year. The determination depends on where your main residence is for the majority of the tax year, not your employer's location.

Scottish Income Tax replaces the rUK rates on earnings and pensions. The 2026/27 bands, as gross income with the standard Personal Allowance, are: Starter rate 19% (£12,571 - £16,537), Scottish basic rate 20% (£16,538 - £29,526), Intermediate rate 21% (£29,527 - £43,662), Higher rate 42% (£43,663 - £75,000), Advanced rate 45% (£75,001 - £125,140), Top rate 48% (Over £125,140).

Personal Allowance is identical (£12,570 for 2026/27 across the UK). National Insurance is also UK-wide - devolution only covers Income Tax bands and rates.

When you'll see S prefix

You moved to Scotland and HMRC has updated your address - update it through your Personal Tax Account so the prefix follows.
You started a new job and your employer's PAYE feed picked up the Scottish indicator from your Government Gateway record.
You spent the majority of the previous tax year in Scotland and HMRC has confirmed Scottish-taxpayer status for the current year.
Self-assessment users: HMRC determines Scottish status based on your declared residence on the SA return.

What to do if you have a S prefix code

If correct: nothing - your PAYE is correctly calculating Scottish Income Tax. Verify net pay against a Scottish-rates calculator.
If you have moved out of Scotland: update your address via the Personal Tax Account (gov.uk/personal-tax-account) and HMRC will remove the S prefix from the next payroll feed.
If you split residence between Scotland and rUK: HMRC applies the rule of "where you live for the majority of the tax year". For close cases, contact HMRC on 0300 200 3300.
Any incorrect S coding is corrected via subsequent PAYE adjustments or year-end P800 reconciliation.

Worked example

On £55,000 gross in Scotland (S1257L) vs England (1257L): Scottish Income Tax is £11,082 (across the 19%, 20%, 21% and 42% bands); in England it is £9,432. The Scottish taxpayer pays £1,650 a year more on the same salary. National Insurance is UK-wide, so it is identical in both, and the take-home gap is the same £1,650.
