In preparation for a new “mansion tax,” UK tax authorities are set to begin inspecting high-value properties, focusing on those worth more than £2 million. Scheduled to be implemented in April 2028, this council tax surcharge aims to levy additional taxes on luxury homes. Valuation officers will conduct inspections to assess the properties, especially where a home’s internal features and dimensions are necessary to establish its value.
The proposed surcharge outlines specific annual fees based on property value brackets. Homeowners with properties valued between £2 million and £2.5 million would incur an annual charge of £2,500. This fee increases to £3,500 for residences valued up to £3.5 million, £5,000 for those between £3.5 million and £5 million, and £7,500 for homes exceeding £5 million in value. Notably, this surcharge will be separate from existing council taxes and is planned to rise annually in accordance with inflation rates.
Valuation officers will evaluate various aspects such as the property’s size, architectural elements, and the number of bedrooms, bathrooms, and storeys. Property owners are required to cooperate with these assessments, as obstructing officers could result in a £200 fine. Additionally, failing to provide necessary information without a valid reason may attract penalties of up to £500.
The government has assured that these property inspections will be conducted by prior arrangement with the homeowners, adhering to official guidelines. This initiative reflects a broader strategy to ensure that taxation on high-value properties is equitable and reflective of their market valuation.
