In a move to implement a new “mansion tax,” UK tax authorities are gearing up to examine high-value properties across the country. This proposed council tax surcharge targets homes worth over £2 million and is slated to be introduced in April 2028. The initiative aims to determine the precise value of such properties, with valuation officers potentially conducting inspections to assess internal features and measurements.
The surcharge is structured to impose varying annual fees depending on property value. Owners of homes valued between £2 million and £2.5 million would face a £2,500 charge, while those with properties up to £3.5 million would pay £3,500. For more expensive properties, valued between £3.5 million and £5 million, the fee would rise to £5,000. The highest charge, £7,500, is reserved for homes exceeding £5 million in value. Notably, this surcharge will be separate from the existing council tax and is expected to adjust annually with inflation.
As part of the valuation process, inspectors will evaluate several factors, including the property’s size, architectural details, and the number of bedrooms, bathrooms, and storeys. Property owners must be cooperative during these inspections, as any deliberate obstruction of valuation officers could lead to a £200 fine. Furthermore, failing to provide necessary information without a valid excuse could incur penalties of up to £500.
The government has assured that inspections will be conducted in accordance with official guidelines and will be arranged in advance with property owners. This approach seeks to ensure transparency and cooperation as authorities work to implement this new tax measure aimed at the country’s most affluent homeowners.
