I have a query on IHTA 1984 s66(4)(c) in the calculation of the IHT principal charge, the first 10 yearly charge for a discretionary will trust. Under the deceased’s will they set up two discretionary will trusts dated as settled on the same day, but both with initial settlements of £10 to establish the trust. Further funds were then added from the estate. In the calculation of the 10 yearly charge, for s66(4)(c), is the value of the ‘related settlement’ just the £10 and not any subsequent funds added? I have seen it suggested that the effect of s83 is to take the dating of the commencement of the trusts. and any funds comprised in them, to the date of death of the settlor, and I can see that that speaks to the commencement date in particular; but is it clear that this is enough to satisfy the wording in s66(4)(c), ie “the value, immediately after a related settlement commenced, of the relevant property then comprised in it” - even if you take the date the trusts commenced as the date of death, the ‘relevant property then comprised in it’ was just the £10 each.
