Wales (Wales Times) October 24, 2026 – Why are Wales council tax changes facing another delay? Finance Minister Elin Jones has proposed postponing the property revaluation scheduled for April 2028 until 2032, saying the government cannot afford its preferred support package for households facing higher bills. As reported by David Deans of BBC News, the proposal requires Senedd approval and would leave council tax bands based on property values from 2003 for longer.

The announcement, made on 20 October, concerns the timetable for updating property valuations rather than an already completed change to the law. Legislation to defer the exercise is expected to be brought forward in November, with Plaid Cymru requiring opposition support to secure a majority.

According to reporting by Nation.Cymru staff, ministers estimate that helping households through the transition could cost up to £80 million in the first year. Jones said the government would instead examine more targeted ways of improving the system while maintaining its commitment to reform.

Why does the Welsh Government want to delay council tax reform?

Jones said detailed work undertaken over the summer had examined both the practical costs of implementing the revaluation and the financial consequences for households.

As reported by Nation.Cymru staff, research cited by the government suggested approximately one quarter of households could move into a higher council tax band, another quarter into a lower band, while around half would experience minimal change. Some households facing increases could pay hundreds of pounds more each year.

The minister argued that proceeding without adequate protection would create difficulties for households already under financial pressure.

Nation.Cymru quoted Jones as saying: “It wouldn’t have been fair to press ahead with this without fully supporting households, particularly at a time when household budgets are under significant pressure.”

She linked the proposed postponement to wider spending demands, including NHS waiting lists, childcare, employment and education. Jones also cited pressures on public finances and reduced funding coming from the UK Government.

In comments reported by David Deans of BBC News, Jones said she could not risk introducing “new unfairness” and described providing the support she wanted as “extremely challenging”. The estimated £80 million relates to temporary relief in 2028–29, rather than a stated permanent annual cost.

When could the delayed council tax revaluation happen?

BBC News reported that the Welsh Government wants to move the revaluation to 2032, beyond the next Senedd election in 2030. However, the proposed timetable remains dependent on parliamentary approval.

The existing legal framework provides for revaluations beginning in April 2028. Welsh Government guidance explains that the Local Government Finance (Wales) Act 2024 established a five-yearly revaluation cycle to keep property assessments more up to date.

A government explanation of the legislation also states that Welsh ministers have powers to amend future revaluation years when circumstances require it. The law provides flexibility over the organisation and labelling of council tax bands, alongside provisions concerning discounts and people disregarded when liability is calculated.

According to Wrexham.com’s reporting, independent analysis of the effects of revaluation is also due to be published in November. That analysis should provide further information for scrutiny of the proposed delay.

Why has the Institute for Fiscal Studies criticised the proposal?

The Institute for Fiscal Studies argues that postponement would preserve inequalities caused by outdated valuations.

As reported by David Deans of BBC News, IFS economist Stuart Adam said: “There is no principled argument for allowing council tax to become even more out-of-date.”

Adam explained that households living in properties of equal current value can face different bills because their homes had different values in 2003. He described the situation as “simply unfair” and criticised the government’s reasoning as “nonsensical” and “absurd logic”.

His criticism also addressed how transitional support could be financed. Adam argued that ministers could phase in reductions for households benefiting from revaluation to help fund the gradual introduction of increases elsewhere. In his assessment, retaining the current system instead means households that could benefit receive no revaluation-related reduction at all.

An IFS response reproduced by WiredGov also warned that repeated postponements risk making revaluation a continually deferred policy rather than a regular feature of the tax system. It noted that current legislation permits postponement, but not outright cancellation.

What have opposition parties said about the delay?

Welsh Labour’s finance spokesperson Huw Thomas accused Plaid Cymru of failing to follow through on commitments made while in opposition and during its election campaign.

As reported by David Deans of BBC News, Thomas said: “In opposition, Plaid claimed the moral high ground on this issue; in their manifesto they promised action.” He described the retreat as hypocritical and as showing “political and moral cowardice”.

The Welsh Conservatives took a different position, calling for the revaluation to be abandoned altogether.

Nation.Cymru staff reported shadow finance minister Sam Rowlands saying: “Instead of this cynical decision to simply delay this council tax bombshell, Plaid Cymru ministers should scrap it altogether.”

Rowlands also argued that household budgets were already strained and called for a 5% cap on council tax increases, with a local referendum required if a council wanted to exceed it. Those proposals are the Conservatives’ position, rather than measures introduced through the postponement announcement.

Reform UK Wales finance spokesperson Cai-Parry Jones welcomed the pause but criticised the continuing uncertainty.

According to BBC News, he said: “Kicking this into the long grass and breaking their manifesto pledge provides no certainty for households worried about rising council tax bills.” He also opposed measures that could increase bills and called for referendums on increases above 4.99%.

What alternatives are ministers considering?

Jones has maintained that delaying the revaluation does not mean abandoning the objective of making council tax fairer.

As reported by Nation.Cymru staff, she said: “We’ll spend this time looking at other, more targeted ways to improve the system that don’t come with the same price tag, and we welcome any ideas.”

David Deans of BBC News reported that one option Jones wanted to explore was adding further bands for the most expensive properties. The reporting does not establish that ministers have agreed a final design or implementation timetable for that option.

Local government representatives have also called for time to assess the consequences.

Nation.Cymru reported that Welsh Local Government Association leaders would examine the announcement at an executive board meeting that week. Councillor Anthony Hunt, the association’s leader and finance spokesperson, said cooperation between national and local government was essential to understanding the implications and shaping the next steps.

BBC News additionally quoted Hunt, who also leads Torfaen council, saying: “Everyone agrees that we must look for ways to make council tax fairer.” He said local government needed time to consider what the announcement meant for the system’s future.

What is the background to council tax reform in Wales?

Council tax bands in Wales remain linked to property values from 2003. BBC News reported that Wales has nine bands, running from Band A for the lowest-valued homes to Band I for the highest-valued properties. These are historic valuation thresholds, not assessments of present-day sale prices.

The previous Welsh Labour government had already postponed reform from 2025 to 2028. Welsh Government guidance says the slower timetable followed consultation responses favouring a more gradual approach, with further work planned on revaluation, bands and charges.

The earlier delay also had political consequences. Cambrian News reported in July 2024 that Plaid Cymru had cited postponement, alongside concerns about donations to Vaughan Gething’s leadership campaign, when ending its cooperation agreement with Welsh Labour.

During a Senedd debate on 9 July 2024, Plaid Cymru’s Peredur Owen Griffiths sought to require implementation by April 2025. Cambrian News reported that his amendment was defeated by 37 votes to 12. Then-finance secretary Rebecca Evans argued that the amendment was too broad and that delivery by 2025 was no longer feasible.

The 2026 proposal therefore represents another change to a timetable that had already been revised and subsequently underpinned by legislation.

What could the delay mean for Welsh households and councils?

The main prediction supported by the published proposals is that, if the Senedd approves postponement, households will remain within a system based on older property valuations until a later revaluation takes effect. That would defer both revaluation-related increases and reductions rather than benefit every household in the same way.

Households that would otherwise move into higher bands could avoid those particular increases in 2028. Those that would move into lower bands would also have to wait longer for any corresponding benefit. The government-cited estimates describe broad groups, however, and do not establish the outcome for an individual address.

A delay to revaluation should not be interpreted as a general freeze on council tax bills: the announcement concerns the valuation timetable, while the opposition’s proposed caps on annual increases remain separate policy demands.

For councils, the immediate implications remain subject to assessment. Anthony Hunt’s call for joint work reflects the need to understand how revised reform plans would interact with local finances and service provision. The eventual effects will depend on the Senedd’s decision, the independent analysis expected in November and any targeted replacement measures ministers develop.
