What Are Scottish Tax Codes?
A tax code is a shorthand used by HMRC to tell your employer how much tax to deduct from your salary. In Scotland, tax codes begin with the letter “S” to indicate that Scottish income tax rates apply.
How Tax Codes Work
- They reflect your personal allowance (the amount you can earn tax-free).
- They include letters that explain your circumstances, like whether you have emergency coding, allowances, or benefits.
- Your employer uses the code to calculate Pay As You Earn (PAYE) tax deductions automatically.
For example, S1257L means:
- S → Scottish tax code
- 1257 → £12,570 personal allowance for 2025
- L → Standard allowance for most taxpayers
Pro Tip: If your code ends with T, it usually means HMRC has applied multiple adjustments or emergency coding.

Common Mistakes People Make
Scottish Codes ≠ Automatic Higher Tax
Many assume that having an S-code always means you’ll pay more tax. In reality, it depends on your income level and the specific Scottish tax bands that apply to you.
Emergency Codes Are Different
Ignoring emergency tax codes for the moment, regular S-codes work within the standard Scottish rates and bands.
Overpayments Can Happen
If you don’t update HMRC with changes in your circumstances, you may end up overpaying tax.
Keep Your Address Updated
Moving into or out of Scotland mid-year can affect your tax code, so make sure HMRC has your correct address.
SBR vs SD0 Codes
- SBR: Scottish Basic-Rate adjustment. Adjusts your code to account for basic Scottish tax rates.
- SD0: Higher-rate emergency code. Usually applied temporarily if HMRC doesn’t have your up-to-date information.
Mini Case Study:
Anna moved from Edinburgh to Manchester in June. Her employer left S0T on her payslip, leading to temporary overpayment. After updating HMRC, her code was corrected to the standard English code.
