BR vs SBR Tax Code: Key Differences Explained
If you are researching the difference between BR and SBR tax codes, the short answer is: the take-home pay is identical. Both codes tax all income at a flat 20% with no Personal Allowance. The only meaningful difference is the taxpayer's location — BR applies to England, Wales (as BR, or CBR with the Welsh prefix) and Northern Ireland residents, while SBR is exclusively for Scottish taxpayers.
Side-by-side comparison
| Feature | BR | SBR |
|---|---|---|
| Who it applies to | England / NI residents | Scottish residents |
| Tax rate | 20% on all income | 20% on all income |
| Personal Allowance | None applied | None applied |
| Take-home pay | Same as SBR | Same as BR |
| NI deductions | Normal rates | Normal rates |
| Why issued | Second job, no P45 | Second job, no P45 |
Why does the distinction matter at all?
Scotland sets its own Income Tax rates and bands through the Scottish Parliament. Although the flat rate on BR and SBR is 20% in both cases, HMRC needs to track whether income belongs to a Scottish or non-Scottish taxpayer for devolved revenue allocation purposes. A Scottish resident with SBR ensures any tax paid flows to the Scottish government's budget rather than HM Treasury.
The distinction also matters if the income is reassessed. A Scottish taxpayer on SBR who is found to have total income above £43,663 would have their additional income assessed at Scotland's 42% Higher rate — not England's 40%. The S prefix flags this for HMRC's systems.
Common scenarios for each code
BR — who gets it in England:
- Second job where the primary employer holds the Personal Allowance
- New job started without a P45
- Second pension alongside employment
SBR — who gets it in Scotland:
- Same scenarios as BR, but the taxpayer's registered address is in Scotland
- Scottish residents working for a UK-wide employer whose payroll system has correctly identified them as Scottish taxpayers
BR and SBR vs emergency codes
BR and SBR are not emergency codes, though they often appear in similar circumstances. Emergency codes in the UK include:
- 1257L W1 (England — week 1 basis)
- 1257L M1 (England — month 1 basis)
- S1257L W1 / S1257L M1 (Scotland equivalents)
- OT (no allowance, all bands)
If you receive BR or SBR on what you believe is your only job, contact HMRC on 0300 200 3300 to get the correct code issued.
Frequently asked questions
What is the difference between BR and SBR?
The only difference is your tax residency. BR applies to taxpayers in England, Wales and Northern Ireland. SBR applies to Scottish residents. Both tax all income at 20% with no Personal Allowance, producing identical take-home pay.
I live in Scotland but my employer uses BR — is that wrong?
It may be. If your employer has not identified you as a Scottish taxpayer, they may be using BR instead of SBR. Inform HMRC via your Personal Tax Account, and update your employer with your correct address. For the current year, the tax deducted is the same either way.
Will switching from BR to SBR change my pay?
No, not at the 20% flat rate. The practical difference only emerges if your income is subsequently reassessed at a Scottish band that differs from the equivalent English band (e.g. Scotland's 42% Higher rate vs England's 40%).
