Wales has had the power to set its own income tax rates since 6 April 2019 — but has not yet used that power to diverge from England. In 2026/27, Welsh taxpayers pay exactly the same income tax as their English counterparts. Here’s what the Welsh income tax framework means in practice.
Welsh Income Tax Rates 2026/27
| Band | Welsh rate | England rate | Difference |
|---|---|---|---|
| Personal allowance | £12,570 (0%) | £12,570 (0%) | None |
| Basic rate | 20% | 20% | None |
| Higher rate | 40% | 40% | None |
| Additional rate | 45% | 45% | None |
| Higher rate threshold | £50,270 | £50,270 | None |
All figures assume standard personal allowance. Welsh rates match England exactly in 2026/27.
How Welsh Income Tax Works Technically
The Wales Act 2014 created the Welsh Rates of Income Tax (WRIT) mechanism. The process:
- The UK Government reduces the UK income tax rates for Welsh taxpayers by 10p in each band
- The Welsh Government then sets Welsh rates to replace those 10p
- If the Welsh rate exactly matches the UK reduction (10p = 10p), the effective rate is identical to England
Currently, the Welsh Government sets each of its three Welsh rates at 10p — meaning the total rate is 20% basic, 40% higher, 45% additional. This is indistinguishable from England in practice.
Where the power actually lies: The Welsh Government can set its three rates at anything from 0p to 20p (replacing 0p–10p reductions from UK rates). But it cannot change:
- The personal allowance
- The higher rate threshold
- The additional rate threshold
- National Insurance contributions
Your Tax Code — ‘C’ Prefix Explained
Welsh taxpayers have a ‘C’ prefix added to their PAYE tax code:
| Code | What it means |
|---|---|
| C1257L | Welsh taxpayer, full personal allowance |
| C1257L M1 | Welsh taxpayer, month 1 basis |
| 1257L | Not Welsh — England or Northern Ireland |
| S1257L | Scottish taxpayer |
The ‘C’ instructs your employer’s payroll software to apply Welsh rates when calculating your PAYE. Since rates currently match England, your monthly take-home pay is the same as an equivalent English earner.
If you see a wrong prefix: Check via your personal tax account at gov.uk. If you’ve moved from England to Wales (or vice versa) recently, notify HMRC to get your code updated.
Am I a Welsh Taxpayer?
| Situation | Welsh taxpayer? |
|---|---|
| Live in Wales, work in Wales | ✅ Yes |
| Live in Wales, work in England | ✅ Yes — residence determines it |
| Live in England, work in Wales | ❌ No |
| Split time between Wales and England | Depends on main residence (HMRC decides) |
| Student living in Wales during term | Depends — main home may still be England |
| Just moved to Wales | Yes, from when your main residence is Wales |
Scotland Comparison
Scotland set different income tax rates from England since 2018 — illustrating what Wales could do:
| Band | Scotland 2026/27 | Wales/England 2026/27 |
|---|---|---|
| Starter rate (up to ~£14,876) | 19% | 20% |
| Basic rate | 20% | 20% |
| Intermediate rate (up to ~£31,092) | 21% | 20% |
| Higher rate | 42% | 40% |
| Top rate | 48% | 45% |
Scottish higher earners pay meaningfully more income tax than Welsh or English equivalents. The Welsh Government has a comparable power but has not yet exercised it.
What This Means for Your Payslip
Currently: nothing changes on your payslip compared to an English earner. The ‘C’ code has no practical effect when rates are identical.
If Wales diverges in future: Your employer’s payroll system automatically applies the Welsh rate via your ‘C’ tax code — no action needed from you. HMRC manages the split of tax revenue between the UK and Welsh governments.
