Tax Code SBR Explained

What does SBR mean?

SBR marks you as a Scottish taxpayer for the 2026/27 year. The personal-allowance logic is identical to the rUK version of BR - the number still represents your tax-free amount, the letter still describes any allowance adjustment - but Holyrood (not Westminster) sets the rates above the allowance. The 2026/27 Scottish bands are: 19% starter rate on the first slice above your allowance, 20% basic rate, 21% intermediate rate, 42% higher rate, 45% advanced rate and 48% top rate above £125,140. HMRC determines residency from your main home, not your employer's location, so a Scotland-based employee at a London-headquartered firm will still be issued an S code. National Insurance is unaffected and continues to use UK-wide thresholds. SBR deducts the Scottish basic rate of 20% from every pound of pay from this source, with no tax-free allowance and no other band applied. HMRC's instruction for the code is simply to multiply the whole pay by 0.20. It normally appears on a second job or a pension running alongside a salary, because your £12,570 allowance has already been allocated to your main source of income, and in that position it is correct. It is wrong — and expensive — when it is applied to your only job, which usually traces back to a missing P45 or a Statement C tick on the starter checklist.

How Scottish S-prefix tax codes work

Breakdown of the code

• S

  S

  Scottish prefix - you live in Scotland and pay Scottish income-tax rates (19% / 20% / 21% / 42% / 45% / 48%).

• BR

  Letter pair

  Basic Rate - flat 20% (the Scottish basic rate) on every pound, with no tax-free allowance applied at this source.

Worked example

Second job in Scotland - Saturday retail role on £8,000 (paid monthly).

£8,000 × 20% = £1,600/year. Correct because the £12,570 allowance is allocated to the main job.

Who should be on SBR?

• Scottish residents whose main home address is in Scotland
• Second jobs where the personal allowance is consumed by the primary employment
• Private pensions paid alongside a salary
• Freelance retainers paid via PAYE
• Short-term holding code while HMRC awaits final figures from a previous employer

Common problems

• Applied to your only job - a clear overpayment that needs immediate correction.
• Left in place after the main job ends, so the personal allowance is no longer being used anywhere.
• Accidentally combined with a starter-checklist Statement C tick when Statement A or B was correct.

What to do if SBR looks wrong

1. Sign in to your HMRC personal tax account at gov.uk/personal-tax-account and open the latest P2 (Notice of Coding) - it itemises every adjustment.
2. Compare the code on your most recent payslip with the code HMRC has on file; employers occasionally apply an old code if a P9 was missed.
3. Confirm your employer received your P45, or that you completed a starter checklist if you joined mid-year.
4. Check whether benefits-in-kind such as a company car, fuel, or medical insurance have changed and ask payroll to file an updated P11D.
5. Call HMRC on 0300 200 3300 (Mon-Fri, 8am-6pm) with your National Insurance number if the online tools cannot resolve it.
6. If you have overpaid, HMRC normally refunds via your next payslip once the code is corrected. For closed years request a P800 review.

If you should be on a different code…

Quick decision tree - when SBR is the wrong fit, here is the most likely correct code.

• If you have a single PAYE job and no benefits-in-kind - you should be on 1257L.

  Standard personal allowance of £12,570 for England, Wales and NI.

• If you have moved out of Scotland - you should be on BR.

  All income from this source taxed at 20%, no personal allowance.
