I am sure this is a simple question and would appreciate clarification for clients of mine.
Situation: My clients want to leave everything to each other then their son, but if they all die together (or one partner dies soon after (within 28 days), they each want to make sure bank accounts and ISAs are passed to their own sister(s) with the remaining estate (including the home) is passed to both sets of sisters split equally. I have advised them that this would not be very tax efficient due to one owning more than the other, but for the purpose of my question, lets assume they have included a 28-day survivorship clause.
If the couple has different asset values and one has more than the NRB & RNRB whereas the other has less than the NRB, if they include the survivorship clause and they both die in quick succession or exactly at the same time, the person who has a higher estate value, can they claim their civil partners unused NRB and RNRB (if left to their son) or can they only claim it if they died second. For example:
A has £690K in their estate – A dies on 01.08.2023 she has a 30-day survivorship clause. House worth £749,500 and A owns £637,000 (85%) – A is older than B
B has £300K in their estate – B dies on 20.08.2023 she has a 30-day survivorship clause. House worth £749,500 and B owns £112,500 (15%) – B is younger than A
Can A’s executors claim part of B’s NRB i.e. 7.5% unused NRB and can they also claim all of the £175,000 RNRB from B, resulting in no IHT payable for either of them?
I presume if B dies first in the above situation then A can claim B’s unused NRB & RNRB?
Thanks in advance.
