Scotland tax checker (S-prefix codes)

The problem

Scottish income tax has its own bands and rates that differ from England, Wales and Northern Ireland. If you live in Scotland but your payslip shows a non-S code, payroll is taxing you under the wrong regime.

The wrong regime can cost (or save) hundreds of pounds depending on your income. PayslipIQ flags a missing S-prefix and shows what the bands should produce.

Plain-English explanation

For 2026/27 Scottish income tax has 5 bands:

• Starter rate 19% — over the personal allowance up to £14,876.
• Basic rate 20% — £14,877 to £26,561.
• Intermediate rate 21% — £26,562 to £43,662.
• Higher rate 42% — £43,663 to £75,000.
• Advanced rate 45% — £75,001 to £125,140.
• Top rate 48% — above £125,140.

You qualify as a Scottish taxpayer if Scotland is your sole or main place of residence for the majority of the tax year. Residency is determined by HMRC based on the address you report.

NI, student loan, pension and most other deductions follow UK rules — only the income tax bands change. Scottish students fall under Plan 4: 9% above £31,395 (2026/27).

Step by step

1. 1

   Confirm the S prefix

   Your payslip should show a code starting with S — for example S1257L. If it does not and you live in Scotland, payroll is taxing you under the wrong regime.

2. 2

   Check residency record at HMRC

   HMRC tags you as Scottish based on your address. If you moved to Scotland, ensure HMRC has the new address via your personal tax account.

3. 3

   Reconcile the bands

   Use the 5-band table above against your annualised pay to estimate Scottish tax for the period.

4. 4

   Confirm Plan 4 for student loan

   Scottish graduates fall under Plan 4. The threshold is £31,395 (2026/27) at 9%.

What to ask payroll

• ?Is my tax code currently S-prefixed (S1257L, SBR, etc.)?
• ?When did you last receive a Scottish residency flag for me from HMRC?
• ?If I moved to Scotland, when did the S-prefix start applying?
• ?Am I on Plan 4 for student loan?
• ?Have you applied the 5 Scottish bands for this period?

When to contact HMRC

• Use your gov.uk personal tax account to check your residency record and update your address.
• If you have been on a non-S code while resident in Scotland, HMRC will reissue an S-prefix code and the over-paid (or under-paid) tax will normally rebalance through payroll.
• For prior-year reconciliation, file a tax return or use form P53 / P55 / P50 as relevant.

FAQ

How do I know if I am a Scottish taxpayer?

You qualify if Scotland is your sole or main residence for the majority of the tax year. HMRC determines this from your address.

Why does my Scottish payslip show different income tax?

Scotland has 5 income tax bands rather than 3, with different thresholds. The S-prefix tells payroll to use the Scottish bands.

Does NI also change in Scotland?

No. National Insurance rates and thresholds are UK-wide. Only income tax bands differ.

What about student loan in Scotland?

Scottish graduates fall under Plan 4 — 9% above £31,395 (2026/27). The other plans apply if you studied elsewhere.

I moved to Scotland mid-year. What happens?

HMRC will switch you to S-prefix from the date of residence change. Payroll applies the new code from the next available period and may rebalance over the rest of the year.
