Dear Sir/Madam
Inquiry into the Impact of variations in national and sub-national income tax - Consultation
Since April 2018, the Welsh Government has had responsibility for some of the taxes paid in Wales, including the new Welsh Rates of Income Tax (WRIT) that came into force in April 2019. In light of these new taxation powers, the Finance Committee is undertaking an inquiry into the Impact of variations in national and sub-national income tax. The terms of reference for the inquiry are:
§ To examine the effects of sub-national income tax variations in international tax systems on the behaviour of low, medium and high income earners, particularly migration and tax avoidance.
§ To understand how low, medium and high income earners may respond to income tax rate divergence for each tax band between Wales and England.
§ To understand the level of divergence in income tax rates that could trigger a behavioural change in low, medium and high income earners in Wales and England.
§ To assess the monetary impact on WRIT revenue with varying levels of tax rate divergence.
Further details about the inquiry can be found on the Assembly’s website:
