The UK government is set to implement a new council tax surcharge, widely known as the “mansion tax,” targeting high-value properties starting April 2028. This levy will apply to homes worth more than £2 million. In preparation for this, tax authorities are gearing up to conduct inspections of these properties to accurately assess their value.
Owners of properties within the £2 million to £2.5 million range will incur an annual surcharge of £2,500. Those with homes valued up to £3.5 million will face a £3,500 charge, while owners of properties worth between £3.5 million and £5 million will need to pay £5,000. For the most expensive properties exceeding £5 million, the surcharge will rise to £7,500. This additional charge will exist separately from the current council tax and is expected to adjust annually in accordance with inflation rates.
To determine property values accurately, valuation officers will conduct inspections focusing on various factors such as property size, architectural details, the number of bedrooms and bathrooms, and the number of storeys. These assessments will be crucial in categorizing properties under the new tax system. The government has assured that these inspections will be conducted in agreement with property owners and will adhere to official guidelines.
In cases where property owners hinder valuation officers, a fine of £200 could be imposed. Furthermore, failing to provide necessary information without a reasonable excuse could result in penalties as high as £500. These measures are part of the government’s efforts to ensure compliance and transparency in the valuation process.
