IHTM35081 | How many variations can be attempted?: introduction
From HM Revenue & Customs · Inheritance Tax Manual
The published guidelines (IHTM35021) set out the following broad framework in which to consider when several variations can be made. This is that
an election which is validly made is irrevocable
an instrument will not fall within IHTA84/S142 if it further redirects any item or any part of an item that has already been redirected under an earlier instrument
to avoid any uncertainty variations covering a number of items should be made in one instrument
multiple instruments which lie outside these guidelines will have to be considered individually to determine whether or not they qualify.
