Major reforms to council tax and business rates cleared the first hurdle in the Senedd.

MSs backed the general principles of the local government finance bill, which would introduce a five-year cycle for council tax revaluations from 2030.

The bill would lay much of the groundwork for Welsh Government proposals to redesign council tax, with current bands based on property values from 2003.

It would also increase the frequency of business rates revaluations from five to three years.

Rebecca Evans told the Senedd the bill forms a vital part of the Welsh Government’s wider programme of local tax reform.

Wales’ finance minister explained the bill would enable ministers to modify business rate relief exemptions and the multiplier to support policy priorities.

John Griffiths outlined the local government committee’s stage-one report recommendations aimed at improving the bill and guarding against unintended consequences for taxpayers.

Mr Griffiths explained that the bill provides a framework for future policy changes to be made by the Welsh Government via secondary legislation.

The Labour MS said the committee heard concerns that this limits opportunity for public engagement and scrutiny by the Senedd.

Welcoming the Welsh Government’s commitment to retaining the single-person council tax discount at 25 per cent, he highlighted wide-ranging powers in the bill over vital reduction schemes.

In terms of business rates, the committee chair said MSs heard broad support for a move to three-yearly revaluations, which he described as a reasonable, proportionate cycle.

Peredur Owen Griffiths, who chairs the finance committee, backed the bill’s key aim to create a fairer, more flexible system.

The South Wales East MS welcomed reassurances from the Welsh Government that the intention of council tax reforms is not to raise more revenue.

“Given the regressive nature of council tax, we support the aim to make it fairer without affecting the tax base,” he said.

Plaid Cymru’s finance secretary said the proposed powers will reduce the Welsh Government’s reliance on UK bills to make changes.

Sam Rowlands, the Tories’ shadow local government secretary, raised concerns about the bill putting more power in the hands of the Welsh Government rather than councils.
