Payslip Checker for Glasgow on Tax Code SD1

Glasgow is a large urban workforce of around 640k residents in Strathclyde, Scotland. Median full-time gross pay for the area sits near £32,800 per year (ONS ASHE 2024), and most local employees see their PAYE deducted before they ever check the breakdown. This page focuses specifically on what tax code SD1 should look like on a Glasgow payslip. Because SD1 is a stable PAYE code, the monthly figures should be broadly consistent across the tax year. Because you live in Scotland, your code should start with S — and SD1 already does, so the Scottish bands apply.

What does SD1 mean for Glasgow workers?

SD1 applies a flat 42% to every pound under this employment. In Glasgow, this is most often a second-job code — for example NHS bank shifts at a local trust on top of a substantive role. Glasgow payroll teams running Scottish residents on an English-prefixed version of this code is one of the most common payslip errors we see locally.

Scottish equivalent of D1. All income under this employment is taxed at the Scottish higher rate (42% in 2026/27). Used on additional sources of income for higher-band Scottish taxpayers.

Effective tax + NI rate on this salary: 46.9%. Estimates based on ONS ASHE median earnings 2024 — your actual pay may differ.

Local context for Glasgow

Scottish residents pay Scottish income tax across six bands (Starter, Basic, Intermediate, Higher, Advanced and Top) for the 2026/27 year. If your home address is in Glasgow but your employer's payroll office is in England, the prefix is set by HMRC based on residence — not by where the payroll runs. National Insurance is unchanged across the UK. HMRC's East Kilbride office handles Scotland-specific PAYE corrections.

Common payroll questions in Glasgow

Should my Glasgow payslip show tax code SD1?

SD1 should appear if your circumstances match what HMRC expects for this code (scottish higher-rate flat code at 42%.). On a typical Glasgow salary of £32,800 you would expect roughly £1,148 of income tax per month under this code.

Why does my Glasgow payslip differ from a colleague's on the same code?

Two Glasgow colleagues on tax code SD1 can still see different deductions because pension contributions, salary sacrifice, student loan plan, taxable benefits and overtime all sit alongside the tax code. The code only governs the income-tax line. Match the code first, then check pension and NI category, then the variable lines.

Do Scottish income tax rates change my Glasgow take-home on SD1?

Yes. Scottish bands differ from rest-of-UK bands above £43,662, so a higher earner in Glasgow on a Scottish-prefixed code can pay several hundred pounds more per year than a colleague on an English-prefixed code at the same salary. This page already uses Scottish bands.

What should I do if SD1 looks wrong on my Glasgow payslip?

Start with your most recent payslip and your latest HMRC P2 coding notice. If the code on your payslip does not match the code on the P2, the employer is the right first call. If they match but the figure looks wrong, contact HMRC on 0300 200 3300 — your tax code is set by HMRC, not by your Glasgow employer.
