The Seven Year Cumulative

Hi Sir

I’ve got a number of questions related to the cumulative seven year donor period. I hope I have written them clearly enough:

1. Is it right that: after seven years have lapsed from an initial gift made to a trust, a full £325k or less can be again gifted to a trust and the entire amount would not incur an immediate charge?

2. So, if £325k were gifted, into a trust, in Jan 2010 and then £325k in Jan 2019 (into a trust again), neither of the two CLT gifts would incur an immediate charge to IHT?

3. However, on death, would the second transfer be fully chargeable on death, at 40% – because the NRB can only be awarded once, when calculating IHT chargeable at death or would the £325k NRB still apply – despite the fact that it has already been used during lifetime?

4. Alternatively, if a single gift, to a trust, of £325k was made in Jan 2011 and then the donor dies in Feb 2019, would a full, “renewed”, £325k be available against the death estate, despite £325k being awarded against the initial £325k CLT?

Slightly Different Q (and time periods):

5. If the NRB in force, say in Jan 2008, was lower than £325k (say £300k), but all the NRB was used in 2008, would the difference between the amount of NRB available in 2015 (within the 7 year period) compared to 2008 (so in this instance £25k) be awardable as an increment of NRB on any CLTs made within this period where the NRB was higher?

Thank you
