From 6 April 2019, income tax rates paid on non-savings, non-dividend (‘NSND’) income by Welsh taxpayers fell by 10p in the pound and were replaced by the Welsh Rates of Income Tax.

Keeping tax rates paid by Welsh taxpayers unchanged by setting a 10p rate in each band is forecasted to raise over £2 billion for the Welsh Government in 2024-25, based on data and OBR forecasts December 2023.

This model has been updated by Senedd Research based on analyses produced by Welsh Government and researchers from the Wales Fiscal Analysis team at Cardiff University’s Wales Governance Centre.

Use the controls to vary the income tax rates and behavioural changes and see the estimated effects on the Welsh Government's income tax revenue. Enter your annual taxable income to see how much you pay, or would pay, the Welsh and UK Governments.

*Were the Welsh Government to change income tax rates in Wales, there would likely be some behavioural response from Welsh taxpayers. Possible behavioural responses include greater use of tax planning, tax avoidance or evasion, individuals seeking different jobs or changing the number of hours worked, and/or migration into and out of Wales. The extent and effects of behavioural change to be expected is highly uncertain, though it must be considered when setting income tax policy. Migration has not been included in the behavioural response analysis.

'My Taxable Income' reflects 2024-25 allowances in the UK Autumn Statement 2023.
