Interest rates change from time to time along with market rates. The following table shows interest periods and rates since October 1988. You can use this to work out how much interest is due on an Inheritance Tax payment.
If you pay too much Inheritance Tax in advance HM Revenue and Customs will refund any excess money to you plus interest on the amount you’ve overpaid. This rate of interest is displayed in the Interest on repayments column below.
