This is a schedule to form IHT400 (Inheritance Tax account). It is required to pay or opt out of the lower rate of inheritance tax (IHT) of 36% for testators who leave 10% of their net estates to charity, or to elect to merge components of the estate for this purpose.

For information about the reduced rate of IHT, see Practice note, Inheritance tax: leaving 10% of an estate to charity. For IHT forms and guidance, see Practice note, HMRC inheritance tax accounts: resources.
