UK launches home inspections to determine 'mansion tax' wealth surcharge

The UK tax authorities plan to send inspectors to high-value properties to determine ownership and assess whether homes are worth over £2 million to collect a new wealth tax. The levy, known as the mansion tax, was introduced by former Chancellor Rachel Reeves in the previous budget and will take effect in April 2028. Property owners would be required to pay £2,500 annually for homes valued between £2 million and £2.5 million, £3,500 for properties up to £3.5 million, £5,000 for homes between £3.5 million and £5 million, and £7,500 for properties worth more than £5 million. The surcharge is separate from council tax and will increase with inflation.

Inspection units, part of HMRC, will assess the size, architectural style, number of rooms, and other details of the properties. Failure to cooperate with valuation officers could result in a fine of up to £500. The Valuation Office Agency, responsible for assessing council tax bands, may require additional staff to handle the workload of the new tax enforcement.

Critics argue that the tax will place a burden on hard-working families and pensioners, as even properties below the tax threshold may face intrusive checks. Supporters, on the other hand, believe that the tax is necessary to address the inflated house prices in London's high-end areas and to free up housing stock for local residents.
