If the joint policyholders are the beneficial owners of the policy (i.e. not merely trustees) difficulties can arise in determining what beneficial interest each has and therefore what claims for tax there are - particularly on the death of the first to die. There are three possibilities:
In this case the share of the first to die forms part of their estate and, subject to exemptions, Inheritance Tax is payable on the value of that share - see IHTM20211.
In this case the same consequences will follow. In husband and wife or civil partner ( IHTM11032) cases, however, spouse or civil partner exemption will usually be available.
In this case the interest of the first to die is completely extinguished at that time and does not pass either under the will or by survivorship. There is therefore no property to tax on that event.
