The UK’s tax authorities are set to initiate inspections of high-value properties as they prepare to implement a new council tax surcharge, popularly known as the “mansion tax.” This levy will target homes valued over £2 million and is slated for introduction in April 2028. To accurately assess a property’s value, valuation officers may conduct inspections that require an evaluation of internal features or specific measurements.
According to the proposed structure, property owners with homes valued between £2 million and £2.5 million would incur an annual charge of £2,500. This charge escalates to £3,500 for properties worth up to £3.5 million, £5,000 for those between £3.5 million and £5 million, and reaches £7,500 for homes exceeding the £5 million mark. The surcharge is designed to function independently from the existing council tax and will likely see annual adjustments based on inflation rates.
Inspection criteria include factors such as the size of the property, architectural details, the number of bedrooms and bathrooms, and the number of storeys. Property owners who obstruct the work of valuation officers intentionally could face fines of £200. Furthermore, those who fail to provide necessary information without a valid excuse may be subject to penalties reaching up to £500.
The government has assured that all property inspections will be conducted with the prior consent of homeowners and will adhere to official guidelines. This approach aims to ensure transparency and cooperation between the authorities and property owners, as they navigate the implementation of this new tax measure.
