HMRC valuation teams are expected to visit high-value properties in England as the government prepares to introduce the High Value Council Tax Surcharge, commonly referred to as the mansion tax.
The new charge is due to take effect from April 2028 and will apply to properties valued at £2 million or more. Unlike standard Council Tax, which is generally paid by the person living in the property, the surcharge will be charged directly to the property owner.
Property Inspections Planned
HMRC valuation agents will assess properties to determine whether they meet the £2 million threshold. Their inspections are expected to include both the value of the property and details such as the number of rooms, bedrooms, bathrooms and storeys.
Property owners who refuse to allow an inspection could face a fine of up to £200, with refusal reportedly treated as a criminal offence.
The government is expected to use several methods when assessing property values rather than relying solely on physical inspections.
How Much Will the Mansion Tax Cost?
Owners of qualifying properties in England will face an annual charge of £2,500 for homes valued at £2 million or more.
Higher charges will apply to properties above additional value thresholds, including £2.5 million, £3.5 million and £5 million.
According to estimates from Zoopla, around 183,000 homes in England could currently fall within the £2 million-plus category. A further 75,000 properties are estimated to sit just below the threshold.
This means a significant number of homeowners could find themselves affected if their property values rise above the £2 million mark.
Concerns Over Property Inspections
The planned home visits have already attracted criticism, particularly from opposition politicians and property owners concerned about privacy.
Critics have questioned whether government officials should have the power to enter privately owned homes to carry out valuations.
Supporters of the policy, however, argue that physical assessments may be necessary to ensure properties are valued accurately and that the surcharge is applied fairly.
The government has said that different valuation methods will be considered as part of the process.
What Does This Mean for Landlords?
The changes could also have implications for landlords with high-value rental properties.
Owners of expensive rental homes may need to factor the additional annual charge into their property costs from 2028. Depending on the individual property and rental market, some landlords could look at whether the additional cost should be reflected in future rent increases.
For landlords considering buying or holding high-value properties, the new surcharge will also become another cost to consider alongside mortgage interest, maintenance, insurance and other property-related expenses.
Mansion Tax Starts in 2028
The High Value Council Tax Surcharge is scheduled to come into force in April 2028, giving property owners time to understand how the new valuation process will work.
With HMRC expected to assess high-value properties and potentially carry out physical inspections, homeowners and landlords with properties approaching the £2 million threshold may want to keep a close eye on further guidance.
The introduction of the surcharge represents another significant change to the tax treatment of high-value property and could have wider implications for homeowners, landlords and the UK housing market.
