HMRC mansion tax inspectors to target homes for property valuations

The UK's HMRC will dispatch mansion tax inspectors to residences across the country to assess whether homeowners should be subject to the new levy. These inspectors will have the authority to enter properties to determine if they are valued at over £2 million, qualifying them for the High Value Council Tax Surcharge, also known as the mansion tax.

Introduced by the former chancellor Rachel Reeves in the autumn budget of the previous year, the mansion tax levy is set to commence in April 2028, following a consultation on the new levy that concluded in July. The charge will apply to properties exceeding £2 million, with an additional levy of £2,500 to £7,500 annually, depending on their value.

Failure to permit the inspectors entry into a property could result in fines of up to £200, constituting a criminal offense, as reported by The Telegraph. To identify which homes will be subject to the charge, HMRC's valuation agents will rely on third-party data and publicly available information to estimate property values. The Valuation Office, a division of HMRC responsible for monitoring council tax bands in England and Wales, will conduct inspections where "attributes can only be confirmed internally or a re-measurement is required".

During these assessments, inspectors will examine property interiors, evaluating aspects such as size, architectural style, as well as the number of bedrooms, bathrooms, and storeys. It is anticipated that the mansion tax will impact 165,000 homeowners in its inaugural year, surpassing the initially projected 120,000. An additional 45,000 homes will be subjected to the levy, according to HMRC's fiscal watchdog, with thousands of individuals potentially eligible to contest the tax.
