IHT38: claiming Inheritance Tax back on property sold at a loss

HMRC form IHT38 is how executors claim Inheritance Tax back when an estate's land or buildings were sold for less than their value at death.

Who must sign it

The claim must be made by the "appropriate persons": the people liable for the Inheritance Tax on the property, usually all the executors or administrators. Every one of them must sign, in ink. HMRC does not accept an IHT38 signed only by an agent, but you can name an agent as the contact HMRC deals with.
