IHTM11114 | General outline: quantifying the exemption
From HM Revenue & Customs · Inheritance Tax Manual
When considering the extent of any exemption you should look out for situations where
lifetime transfers (IHTM11013) are involved
the transfer is only partly exempt (IHTM26001)
the deceased is domiciled outside the UK (IHTM11013)
the exemption has a value limit. Inheritance Tax has no value limit. However, until 1983 there was a value limit on the corresponding exemption for Capital Transfer Tax. The limit was removed by F(No.2)A 1983. If you need to consider a transfer made before 15 March 1983 seek advice from Technical.
