How is SBR different from BR (without S prefix)?

BR applies the rest-of-UK Basic Rate (20%) - the same numerical rate as Scottish Basic Rate, so the cash result is identical. The difference is administrative: SBR correctly identifies the employment as Scottish-taxed, ensuring revenue allocation to the Scottish Government. BR codes Scottish income to rest-of-UK revenue pool by mistake.

Can I have SBR on my primary job?

Unusual but possible. SBR on primary employment would mean no PA applied - typically only happens if your tax code has been adjusted for a specific reason (e.g. recovering tax debt). Most primary-job Scottish employees use S1257L.

What about Scottish second jobs that should be at higher rate?

Use SD1 (42% Scottish Higher Rate flat), SD2 (45% Advanced Rate flat) or SD3 (48% Top Rate flat) depending on which Scottish band the secondary employment falls into when combined with primary income. SD0 applies the 21% intermediate rate. SBR only works when total income stays in Scottish Basic Rate band.

SBR Tax Code: Scottish Basic Rate Flat 20%

SBR codes a Scottish taxpayer at the 20% Basic Rate on every pound of income from this employment, with no Personal Allowance applied. Used most often when your primary job has already used your full PA, and a second job needs all income taxed.

What the SBR tax code means

SBR is the Scottish prefix (S) + BR (Basic Rate) combined. It applies the 20% Scottish Basic Rate to all income from this employment.

The S prefix tells PAYE you are a Scottish taxpayer. BR (Basic Rate) means no Personal Allowance applied - every pound is taxed at the Basic Rate. The Scottish Basic Rate band 2026/27 is £16,538-£29,526 of total income (£3,968-£16,956 of taxable income above the PA).

Note: SBR does NOT use the Scottish Intermediate (21%), Higher (42%), Advanced (45%) or Top (48%) rates - it applies flat 20% regardless of total income. This makes SBR a poor fit for second-job Scottish taxpayers whose primary employment pushes total income into the Higher band - they would need SD1 (higher), SD2 (advanced) or SD3 (top) instead.

When you'll see SBR

You have a second job in Scotland and your primary job has already used your full Personal Allowance.
You have a pension drawdown alongside continuing employment and HMRC has flagged the smaller income source for SBR coding.
You started a new Scottish-employed job mid-year and your previous P45 showed PA already fully used at the previous employer.

What to do if you have a SBR code

If your total combined income remains in the Basic Rate band: nothing - SBR is the correct code.
If your total combined income crosses into Higher Rate (above £43,662 for Scotland 2026/27) and this employment is the higher-paying one: you will under-pay tax during the year. Contact HMRC to switch the secondary income to SD1 (42% flat) to avoid year-end Self Assessment liability.
If you believe the S prefix is wrong (you have moved out of Scotland): update your address via Personal Tax Account. HMRC will reissue BR (rest-of-UK Basic Rate) from the next pay period.

Worked example

On SBR at £8,000 gross from a part-time Scottish job (alongside £30,000 primary employment, which keeps you within the Scottish basic-rate band): all £8,000 taxed at 20% = £1,600. Plus NI as appropriate. If the secondary employment had used a personal allowance code (1257L) instead, it would under-tax the income because the PA is already used elsewhere - SBR correctly captures the right tax for the second job. Note: if your primary pay pushed you into the Scottish higher-rate band (over £43,662), the second job should be SD1 (42%), not SBR.
