IHTM22001 - Interest in unadministered estates and QSR: introduction


Where a person is entitled to an interest in another person's estate ( IHTM04043) and the administration of that estate was not complete by the time the second person died, you may need to quantify the value of the unadministered estate as part of the estate you are looking at. Where inheritance tax was payable in connection with the earlier death you may be able to allow some of that tax as a relief against the tax payable on the second estate. There is a similar relief on lifetime transfers ( IHTM04051) on termination of an interest in possession.


  • This section starts with the procedures for dealing with form IHT415
  • It then goes on to provide more detailed information and guidance about valuing an interest in an unadministered estate ( IHTM22011) and calculating and allowing relief for successive charges (known as Quick Succession Relief ( IHTM22041) or QSR)
  • The section also includes guidance on how to record and cross reference ( IHTM22101) information taken from other estates and transfers and your calculations of relief.
