The annual tax on enveloped dwellings (ATED) applies where a residential property worth over £500,000 is held by a company and is not commercially let out or used for some other qualifying purpose. This tax currently starts at £3,800 per year but that starting rate will rise to £4,150 from April 2023.
Be aware that the ATED charge for 2023-24 to 2027-28 must be based on the property’s open market value on 1 April 2022 and it is up to the property owner to provide that valuation.
