The government has opened an eight-week consultation on the design of its High Value Council Tax Surcharge, a new charge for residential properties in England worth £2 million and above from April 2028.
Consultation sets out how the new surcharge could work
The consultation, launched on 19 May by MHCLG and HM Treasury, asks for views on how the surcharge should be structured, who counts as the owner, which exemptions should apply and how any deferral scheme should work for households that are asset-rich but cash-poor.
Current proposals would add a £2,500 annual surcharge for homes worth £2 million to £2.5 million, rising to £7,500 for properties worth more than £5 million. The charge would sit on top of existing council tax bills rather than replace them.
For property investors, this is not just a prime-owner story. It matters to landlords holding high-value stock in London and the South East, to company-owned residential property, and to anyone thinking about future acquisition structures in the upper end of the market. It also adds another layer of tax risk to a part of the sector that already faces sharper scrutiny.
The move lands after Landlord Knowledge’s report on landlords’ stamp duty burden and our recent coverage of tax policy feeding into rent and investment decisions. The new High Value Council Tax Surcharge consultation suggests tax reform remains firmly in play for residential property, especially where ministers think the political optics are favourable.
Deferrals and company ownership will matter most to landlords
The consultation says legal owners would be liable, including companies where a property is held through a corporate structure. It also proposes a deferral option for some lower-income households, with eligibility linked to income and savings thresholds.
Landlords with expensive single assets will want to look closely at that detail. A surcharge that looks manageable on paper can still change net yield, resale timing and disposal strategy once it sits alongside mortgage costs, service charges and wider tax exposure. For investors in prime and super-prime markets, the extra annual cost may also weigh on buyer demand and pricing at the margin.
What this means for landlords
- If you own high-value rentals: model the extra annual charge now and test how it affects net yield from 2028.
- Watch for: changes to company treatment, exemptions and deferral rules before the final design is set.
- If you’re buying in prime markets: future tax drag may become another point in price negotiations.
- Bottom line: the consultation is still open, but landlords with £2 million-plus assets should not treat it as background noise.
Editor’s view
Taxes that start at the top rarely stay politically isolated forever. Even if this surcharge only hits a small slice of the market, it reinforces the wider point for landlords: policy risk now sits alongside rent, rates and regulation in every serious investment decision.
