Selling a £2m+ home: what to know about the new mansion tax surcharge
Written by
In the Home Help section of The Times and The Sunday Times, Partner and Head of Residential Property Saskia Arthur addresses a question being asked by homeowners with high‑value property.
She considers whether selling a home worth around £2 million could trigger exposure to the new mansion tax surcharge due to be introduced from April 2028.
Saskia explains that sellers completing before April 2028 will not be liable for the surcharge but highlights why the forthcoming changes are already relevant to market behaviour and decision‑making. She outlines the Government’s proposals for applying the surcharge to residential properties in England valued at £2 million or more, with valuations to be carried out by the Valuation Office Agency.
She also considers how awareness of the new threshold may influence buyer caution and pricing sensitivity, particularly for properties close to £2 million, as well as broader conversations around valuation and timing. While the surcharge will not affect near‑term sales, Saskia notes that it is already shaping how homeowners and buyers think about future transactions.
