SBR Tax Code: What It Means and How to Fix It
The tax code SBR means you are a Scottish taxpayer whose income from a specific employment or pension is being taxed at a flat 20% Basic rate — with no Personal Allowance deducted first. SBR stands for S (Scotland) + BR (Basic Rate). It is the Scottish equivalent of the England BR code and produces the same take-home pay.
SBR is one of the most searched Scottish tax codes because it frequently appears unexpectedly — often when someone starts a second job, switches employers, or begins drawing a pension alongside employment income.
SBR in numbers: take-home pay at common income levels
| Gross income | Income tax (SBR 20%) | National Insurance | Take-home (month) |
|---|---|---|---|
| £15,000/year | £3,000 | £194 | £984 |
| £20,000/year | £4,000 | £594 | £1,284 |
| £25,000/year | £5,000 | £994 | £1,584 |
| £30,000/year | £6,000 | £1,394 | £1,884 |
| £40,000/year | £8,000 | £2,194 | £2,484 |
Why have you been put on SBR?
The most common reasons:
- Second or additional job: Your primary employer holds your Personal Allowance (S1257L). The second employer receives SBR — no allowance available.
- New job, no P45: You started employment without providing a P45 or completing a starter checklist declaring you have no other job. Your employer defaults to SBR until HMRC issues a new code.
- Pension alongside work: You draw a pension while still employed. One source gets the allowance; the other gets SBR.
- Emergency measure: If HMRC cannot determine your correct code immediately, SBR may be applied temporarily.
What to do if SBR looks wrong
If SBR appears on your only income source:
- Check your HMRC Personal Tax Account (gov.uk) — see what code HMRC has on record and why
- Call HMRC on 0300 200 3300 — have your National Insurance number, employer details and recent payslips ready
- Ask your employer or payroll department whether they received a P45 or whether you completed a starter checklist — missing paperwork is the most common cause
If you have overpaid tax under SBR, HMRC will correct your code and the excess will be refunded — either through future payslips (lower deductions) or via a P800 tax calculation at year end.
SBR vs SD1: is there a difference?
SBR and SD1 both apply 20% flat to all income with no Personal Allowance, so the take-home pay is identical. HMRC occasionally uses SD1 instead of SBR in specific band-allocation situations. For most taxpayers, the practical outcome is the same.
Frequently asked questions
What is SBR tax code?
SBR is a Scottish flat-rate tax code: S = Scotland, BR = Basic Rate (20%). All income is taxed at 20% with no Personal Allowance. It appears most often on second jobs or where HMRC lacks full information about your income.
Is SBR an emergency tax code?
SBR is not classified as an emergency code, but it is often applied in similar circumstances — particularly when starting a new job without a P45. If you believe it is being applied incorrectly, contact HMRC.
How long does SBR last?
Until HMRC updates your code. Once they receive the correct information — usually after your first payroll submission — they will issue the appropriate code. This typically happens within a few weeks of starting a new job.
Can I claim back tax paid under SBR?
Yes. If SBR was applied in error on your only job, HMRC will refund the overpaid tax once your code is corrected. For genuine second jobs, no refund is due — the 20% rate is correct.
