How this calculation works
- 01Deduct your Personal Allowance (reduced by £1 for every £2 over £100,000).
- 02Split the rest into basic, higher and additional rate slices.
- 03Apply the UK rate (10p below the normal rate) to each slice.
- 04Add the Welsh rate set by the Senedd to each slice.
- 05Total the two shares to get the Income Tax you pay.
Real payroll can differ because tax and NI are worked out per pay period, and your tax code may include adjustments HMRC hasn't told you about. See our methodology.
How the Welsh bands are built
Welsh taxpayers use the same band limits as England and Northern Ireland. In each band, the UK rate is 10p lower than normal and the Welsh rate is added on top. The total you pay is the sum of the two.
The calculator covers earnings, pensions and self-employed profit. Savings interest and dividends are taxed at UK-wide rates, so they are left out here.
Understanding your welsh income tax calculator result
The headline figure is your yearly Income Tax on earnings as a Welsh taxpayer. The table splits each band into the part collected for the UK Government and the part passed to the Welsh Government, so you can see how the combined rate is made up.
Seeing where your tax goes
Scenario: Enter the annual salary from your contract or the taxable pay figure from your P60, and pick the tax year.
How to use the result: The UK and Welsh shares add up to the tax deducted through payroll. National Insurance is not included, so use the Wales tax calculator if you want take-home pay.
Details to check before relying on the estimate
- You are a Welsh taxpayer if your main home is in Wales, wherever you work.
- Leave out savings interest and dividends, which use UK-wide rates.
- Check your tax code starts with C; if not, tell HMRC your address.
Putting the estimate into perspective
Treat the UK and Welsh shares as parts of one Income Tax total, not extra charges to add on top. This split does not include the other deductions needed for a take-home budget.
