You can use this calculator to work out how much interest is due on a payment of Inheritance Tax.
Interest rates are liable to change at short notice and for that reason this calculator should not be used to work out the interest for periods more than two weeks ahead of today’s date.
Please note that this calculator should only be used to work out interest payments on the Inheritance Tax due on someone’s estate where the death occurred after 18 March 1986. It should not be used for any other purpose.
