The UK government is set to launch a new council tax surcharge, colloquially known as the “mansion tax,” targeting high-value properties. This initiative, slated for implementation in April 2028, will affect properties worth over £2 million. To accurately assess these properties, tax authorities are preparing to carry out inspections focusing on homes where internal features or precise measurements need evaluation.
The proposed surcharge will impose varying annual fees based on property value. Homeowners with properties valued between £2 million and £2.5 million will face an additional £2,500 charge each year. For those with homes valued up to £3.5 million, the fee will rise to £3,500. Properties between £3.5 million and £5 million will incur a surcharge of £5,000, while those valued above £5 million will see their annual charge increase to £7,500. This surcharge will function independently from the existing council tax and is designed to adjust annually in accordance with inflation rates.
Valuation officers will examine various elements of the properties, including size, architectural features, and the number of bedrooms and bathrooms, as well as the number of storeys, to determine the correct valuation. Property owners are advised to cooperate with these inspections, as hindering valuation officers can result in a £200 fine. Additionally, failing to provide necessary information without a valid excuse could lead to penalties 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 aims to ensure transparency and accuracy in the valuation process while avoiding unnecessary inconveniences for property owners.
