Wales to set devolved income tax rates

From April 2019, the National Assembly for Wales will be able to vary the rates of income tax payable by Welsh taxpayers.
Responsibility for many aspects of income tax will remain with the UK government, and the tax will continue to be collected by HMRC for Welsh taxpayers.

The process for setting Welsh rates of income tax
From April 2019, the UK government will reduce each of the three income tax rates: basic, higher and additional rate, paid by Welsh taxpayers by 10 pence.

The National Assembly for Wales will then decide the three Welsh rates of income tax, which will be added to the reduced UK rates. The combination of reduced UK rates plus the Welsh rates will determine the overall rate of income tax paid by Welsh taxpayers.
If the National Assembly for Wales approves each of the Welsh rates of income tax at 10p, this will mean the rates of income tax paid by Welsh taxpayers will continue to be the same as that paid by English and Northern Irish taxpayers. However the National Assembly for Wales may decide to set different rates ‘to reflect Wales’ unique social and economic circumstances’.
