GenzeeUK's New 'Mansion Tax' Consultation Closes for £2m+ Homes
Owners of Britain's priciest homes are a step closer to a new annual bill. The government's consultation on the High Value Council Tax Surcharge — dubbed a "mansion tax" — closed on 14 July 2026, according to reporting by the HomeOwners Alliance. The surcharge will apply to homes valued at more than £2 million, collected alongside council tax starting in April 2028.
What was being consulted on
The consultation covered deferral rules for owners who are asset-rich but cash-poor, a possible surcharge premium for non-resident owners, and how the Valuation Office Agency (VOA) will value affected properties, per the same report. Property income tax rates for landlords are also set to rise separately from April 2027.
Who it affects
Only a small slice of UK homeowners — those in properties above the £2 million threshold — will be liable, but the surcharge adds another layer to an already complex UK property tax picture alongside stamp duty and standard council tax. If you're budgeting for property-related costs or comparing take-home pay against a mortgage, the UK Salary Tax Calculator and Loan / EMI Calculator can help you plan.
