The UK government is setting the stage for a new council tax surcharge, popularly dubbed the “mansion tax,” targeting properties valued above £2 million. This initiative, slated to commence in April 2028, will see tax authorities conducting inspections of high-value homes. These inspections are essential for accurately determining property values, particularly when internal features or specific measurements need to be assessed.
According to the plans, homeowners with properties worth between £2 million and £2.5 million will incur an annual charge of £2,500. For properties valued up to £3.5 million, the surcharge increases to £3,500. Homes priced between £3.5 million and £5 million will attract a fee of £5,000, while those exceeding £5 million will face a £7,500 charge. This surcharge is designed to operate independently from the existing council tax and will be adjusted annually to keep pace with inflation.
Valuation officers will focus on various factors during assessments, including the size of the property, architectural details, the number of bedrooms and bathrooms, and the number of storeys. Property owners who attempt to hinder the valuation process could be subjected to a £200 fine. Additionally, failing to supply necessary information without a justifiable reason may incur penalties of up to £500.
The government emphasizes that these inspections will be conducted with the consent of property owners and in line with official protocols. By ensuring inspections occur under mutually agreed terms, the authorities aim to maintain transparency and fairness in the process.
