IHTM30371 | Special rules: Inheritance (Provision for Family & Dependants) Act 1975
From HM Revenue & Customs · Inheritance Tax Manual
Under this Act () and the corresponding provisions for Northern Ireland, the courts have power in certain circumstances to
change the devolution of a person’s death estate and
require beneficiaries of lifetime gifts to contribute to the donor’s death estate for this purpose.
There are two special rules about interest:
where there is a change in the devolution of a death estate within , any tax payable or repayable as a result of that change does not carry interest from the date earlier than the date of the court order making the change -
if the beneficiary of a lifetime gift has to make a contribution any consequential repayment of tax under on the lifetime transfer carries interest (free of income tax) from the date on which the claim for repayment was made - .
