Transfers of assets between most married couples/civil partners in the UK are exempt from inheritance tax (IHT) whether made at death or during their lifetime. At death transfers from an estate to other persons will generally be subject to IHT unless another relief, exemption or allowance can be set against the value of the transfer.
The nil rate band and the residential nil rate band
Most people living in the UK are entitled to a £325k exemption from IHT on their death, this is known as the ‘nil rate band’, or NRB. If gifts have been made during the deceased’s lifetime – normally within seven years prior to death – the NRB available to be set against the deceased’s estate may be reduced.
In addition to the basic NRB entitlement, if a property has been used as a home at some time prior to death, then a taxpayer may have up to an additional £175k of tax-free allowance. This is known as the ‘residential nil rate band’, or RNRB.
For married couples (including civil partners) unused NRB or RNRB on the first death can be passed to the surviving spouse to provide additional IHT relief on the second death.
For example, on the second death of a married couple a maximum of £1m (£325k x 2 + £175k x 2) can be available where the maximum NRB and RNRB was transferred to that individual on the first death.
The RNRB main conditions
The RNRB is a generous relief and can broadly be claimed where:
Where the value of the estate (excluding any reliefs available) is more than £2m, the RNRB is abated at a rate of £1 for every £2 that the estate value is more than £2m. Full abatement (and no entitlement to the RNRB) therefore arises at £2.35m on the first death, or £2.7m on the second death of a married couple if the full RNRB has been transferred to that spouse/civil partner on the first death.
Further RNRB considerations
Some points to note about the operation of RNRB are as follows:
Next steps
This is a complex relief, and any planning will need to consider the effect of other taxes that may arise based on your personal circumstances. Professional advice is essential to ensure that the optimum overall tax position is achieved.
If you have not considered your will provisions recently or if your circumstances have changed since your will was drafted, we recommend that an assessment is undertaken to ensure maximum value is passed to your legatees.
