Officials are modelling proposals to replace stamp duty and possibly council tax with a national, proportional property levy aimed at homes above \u00a3500,000 \u2014 a move that could spread costs for sellers and high\u2011value owners but risks regional hits, valuation and implementation headaches and political fallout ahead of the Autumn Budget.<\/p>\n<\/div>\n
It is the last thing many hard\u2011pressed homeowners feared: Treasury officials have been asked to model far\u2011reaching changes to property taxation that could shift the burden from buyers to owners of higher\u2011value homes. According to Money Mail and reporting in The Independent, Chancellor Rachel Reeves has instructed officials to explore replacing stamp duty and possibly council tax with a new, proportional property levy that would target homes worth \u00a3500,000 and above as ministers seek ways to close a roughly \u00a351 billion fiscal gap. <\/p>\n
Ministers and officials are understood to be at the modelling stage and have not taken any decisions. The options being examined range from a seller\u2011paid charge on disposals of expensive homes to a two\u2011part system of a national levy on values above a threshold combined with a local property tax in place of council tax. The Independent reported the work is intended to feed into preparatory analysis ahead of the Autumn Budget, while Money Mail set out the particular variants under consideration. <\/p>\n
Under one set of proposals being discussed, the current buyer\u2011paid stamp duty system would be scrapped in favour of a charge payable by sellers on homes above a given threshold \u2014 widely reported as \u00a3500,000. That would represent a significant change to the existing Stamp Duty Land Tax regime, which \u2014 according to HM Revenue & Customs guidance \u2014 charges nil on the initial slices of value for most buyers, then 5 per cent on the portion from \u00a3250,001 to \u00a3925,000, rising to 10 per cent and 12 per cent in the highest bands. Money Mail\u2019s analysis illustrates the difference in scale: stamp duty on a \u00a3600,000 sale currently reaches tens of thousands, whereas a lower, annualised levy would spread that cost over many years. <\/p>\n
The practical and behavioural effects of those options are contested. Andrew Marr, tax expert at Forbes Dawson, told Money Mail the shift would in effect create a luxury tax that risks a two\u2011tier market above and below the chosen threshold and could make owners reluctant to move. The stamp duty holiday during the pandemic is cited as evidence that removing upfront transaction costs boosts activity \u2014 and conversely, that new upfront or ongoing levies could chill moves, reducing downsizing and freeing up larger homes. Some industry figures argue seller\u2011paid levies would be less of a tax on aspiration: Simon Gerrard, chairman of Martyn Gerrard Estate Agents, told Money Mail the change would relieve buyers of the immediate cost of moving, while Aneisha Beveridge, head of research at Hamptons, warned that sellers are likely to fold any new levy into asking prices, fragmenting the market. <\/p>\n
A more developed alternative is set out in Tim Leunig\u2019s Onward report, which has clearly informed the Treasury\u2019s thinking. The paper proposes a local tax on the first \u00a3500,000 of a property\u2019s value (with a minimum payment of \u00a3800) and a national levy on the portion above \u00a3500,000 \u2014 suggested rates of 0.54 per cent between \u00a3500,000 and \u00a31 million and 0.81 per cent above \u00a31 million. Under the report\u2019s worked examples, a \u00a3600,000 home would face a national levy of about \u00a3540 a year and a combined bill (including the local element) substantially lower in any single year than the current stamp duty bill, but persistent and recurring. Onward argues this would make moving cheaper up front, reduce regional unfairness and eventually remove the market distortion caused by a costly transaction tax. <\/p>\n
If a national levy and local replacement for council tax were adopted together, the numbers quickly become material for owners of high\u2011value stock. Money Mail\u2019s calculations \u2014 drawing on the Onward proposals \u2014 show the combined annual charges could be thousands of pounds on homes worth \u00a3800,000 or more and exceed \u00a310,000 a year in the very top\u2011end markets. Tim Leunig told Money Mail his system would encourage mobility because liability would reset on sale and rates would be linked to inflation and periodic revaluations, but he acknowledged the losers would chiefly be those who buy and then stay put for many years. <\/p>\n
The distributional geography matters. Official statistics show sharp regional contrasts: the Department for Levelling Up, Housing and Communities reports the average Band D council tax will be \u00a32,280 in 2025\u201326, while Office for National Statistics data put the average house price in Wandsworth at about \u00a3718,000 in May 2025. Rightmove\u2019s June 2025 analysis also highlights a rise in high\u2011value stock, noting the share of listings at \u00a31 million or more has doubled since 2019 and remains concentrated in London and surrounding boroughs. That combination means many households in the South \u2014 and older owners downsizing within expensive local markets \u2014 are disproportionately likely to face higher ongoing bills under the sorts of regimes under consideration. <\/p>\n
Practical concerns about implementation are widespread. Industry and tax experts have warned about how properties would be valued for tax purposes, whether liabilities would take account of mortgage debt or only market value, and the administrative challenge for HM Revenue & Customs and local authorities. Money Mail quoted tax professionals who said HMRC is already overstretched and that lenders would likely factor any new annual levy into affordability calculations. There is also a risk of a \u201cdouble hit\u201d for existing owners who paid stamp duty when they bought and could subsequently face an annual charge unless the Treasury chooses transitional protections. Landlords, too, could pass new costs on to tenants, according to analysts. <\/p>\n
Politically, the proposals are sensitive. The Independent noted that ministers have not settled on any path and that the measures draw from a centre\u2011Right think\u2011tank\u2019s recommendations, raising questions about timing, electoral reaction and the short\u2011term revenue implications of any move away from stamp duty. Analysts cited by Money Mail, including Tom Bill of Knight Frank, emphasise that a package would need careful calibration to avoid depressing transactions in high\u2011value markets and to manage a potentially large short\u2011term loss of stamp duty receipts. <\/p>\n
For now the work remains modelling rather than policy. Officials are weighing multiple designs \u2014 seller charges on disposal, an annual national levy, reform of council tax \u2014 and significant design questions remain, from valuation rules to transitional arrangements. Homeowners should expect more detail only if and when ministers publish firm proposals in advance of a Budget; until then, the main certainty is uncertainty, and the political battleground over who ultimately pays is only just opening. <\/p>\n
