In the pre-budget report of October 2007, Alistair Darling introduced the Transferable Nil Rate Band.
In the case of a married couple or Civil Partners, the NRB can be transferred to the survivor IF NOT used up by the first to die. The survivor inherits the tax free band at the level it is when the surviving spouse dies and not at the level it was when the first spouse died.
Example 1: Husband and wife both make Wills leaving everything to the other. Husband dies 1 May 2007 (when NRB was £300,000). Wife dies in 2025 when NRB might be £350,000. Wife has a combined nil rate band of £700,000 (not £650,000).
Example 2: Civil Partners’ Wills leave £150,000 to siblings on the first death. Partner 1 dies 5 May 2007 (when NRB was £300,000). The gift to his siblings uses half of his NRB – the other half is transferred to Partner 2. Partner 2 dies in 2025 when NRB might be £350,000. Partner 2 has a combined Nil Rate Band of £525,000 (1.5 x £350,000).
This applies to all existing widows/widowers/civil partners where their spouse/civil partner has already died irrespective of the date of death. It would seem that there can only be one carry-forward in the case of those who marry more than once.
There are many advantages to still incorporating the Nil Rate Band Trust into both wills. Some key benefits are summarised below but a full list of these benefits can be viewed here:
