Welsh taxpayers income tax code mix-up

From April 2019, Welsh taxpayers were assigned new income tax codes beginning with the letter 'C'. However, HMRC recently revealed that some Welsh taxpayers were mistakenly given Scottish income tax codes by their employers. As a consequence, Welsh taxpayers have been charged income tax using the Scottish income tax rates and bands.

For 2019/20 the Welsh rate of income tax is set at 10% and this is added to the UK rates, which are each reduced by 10%. Therefore, the overall tax payable by Welsh taxpayers continues to be the same as English and Northern Irish taxpayers.

The income tax rates and bands that apply to employment income, self-employed trade profits and property income are different for taxpayers who are resident in Scotland, with tax rates and bands ranging from 19% to 46% rather than the 20% to 45% which apply across the rest of the UK. Tax codes for Scottish taxpayers begin with the letter 'S'.

HMRC stated that it does not know the full extent of the error or how many Welsh taxpayers have been affected but they will carry out a review of the operation of Welsh tax codes in June 2019.

Llyr Gruffydd, Chair of the National Assembly for Wales' Finance Committee, said:

'We raised concerns about the flagging process for identifying Welsh taxpayers during our enquiries into fiscal devolution and the Welsh government's draft budget.

'On each occasion, we were told the matter was in hand, and the lessons from the devolution of income tax powers to Scotland, where there were similar issues, had been soundly learned and would be put into effect. We are seeking an immediate explanation of how this has happened and will be asking representatives from HMRC to appear before this Committee in the near future.'
