Background to the report
The Wales Act 2014 amended the Government of Wales Act 2006 to give the Welsh Parliament the power to set the Welsh rates of income tax that will apply to the non-savings, non-dividend income of Welsh taxpayers from the 2019-20 tax year onwards.Jump to downloads
HM Revenue & Customs (HMRC) is responsible for the administration of the Welsh rates of income tax and continues to collect Welsh income tax as part of the UK tax system. HMRC will pay revenues collected in relation to the Welsh rates of income tax to HM Treasury in the same way as it does for all other tax receipts. HM Treasury is responsible for the payment of the Welsh income tax collected to the Welsh Government.
