Depending on their relation to the donor it would be
(Amount of gift ie value of policy minus group threshhold ) x 20%
assuming they have received no other gifts from donor in the same group since Dec 1991
There are 3 groups which are (in a simplified form)
I: received from parents - threshold about 450,000 euro
II: received from brothers/sisters/grandparents/uncles - threshold about 45,000 euro
III: everyone else - threshold about 22,500 euro
CAT is calculated on the accumulated gifts/inheritences received since Dec 1991. If there were prior gifts/inheritences from someone in the same group, then the threshold may already have been used up or partially used up.
