IHTM35154 | IHT implications of an Instrument of Variation: effect of not coming within s.142
From HM Revenue & Customs · Inheritance Tax Manual
A variation or disclaimer may not come within IHTA84/S142(1), because, for example
there is extraneous consideration (IHTM35100)
there is insufficient link with the original disposition (IHTM35025), or
there is no valid statement of intent (IHTM35058) (for variations effected on or after 1 August 2002) or
there is no valid election (IHTM35051) (for variations executed before 1 August 2002)
Or a variation or disclaimer may be only partly within IHTA84/S142(1), for example
where it also deals with property which is not part of the death estate (IHTM35071) for the purposes of IHTA84/S142(1) or
where it purports to reduce the benefits of persons who are not parties to it (IHTM35045).
If a variation does not come within IHTA84/S142(1), or to the extent to which it does not come within IHTA84/S142(1), it operates for IHT purposes in the same way as any other transaction affecting an individual’s own property. It may be a transfer of value and will not be written back into the will or other disposition for the purpose of tax on the death. As a transfer of value it will be either a potentially exempt transfer (IHTM04057) or a transfer chargeable when made (IHTM04067) and will cumulate should the beneficiary making the instrument fail to survive for 7 years after the date of the instrument.
The above also applies to any disclaimer which is not within IHTA84/S142(1), except that in the alternative a disclaimer of an interest in settled property may come within IHTA84/S93.
