The Inheritance Tax Residence Nil Rate Band (RNRB) is a transferable allowance available to married couples and civil partners when their main residence is inherited by direct descendants, such as their children or grandchildren.

The RNRB is available at a maximum allowance of up to £175,000 per person. This allowance can be transferred to a surviving spouse or partner if it remains unused. It is in addition to the existing £325,000 Inheritance Tax (IHT) nil-rate band.

Together with the current Inheritance Tax limit of £325,000, this allows married couples and civil partners to pass on property valued up to £1 million free of IHT to their direct descendants.

However, the transfer of the unused RNRB does not happen automatically; it must be claimed from HMRC when the second spouse or civil partner passes away. Typically, the executor of the estate will file a claim to transfer the unused RNRB from the estate of the first deceased spouse or civil partner. This transfer can also be claimed even if the first spouse or civil partner died before the RNRB was introduced on 6 April 2017.

It is important to note that the RNRB is tapered for estates valued over £2 million, even if the family home is left to direct descendants. For every £2 that the estate exceeds the £2 million threshold, the RNRB is reduced by £1, potentially eliminating the allowance entirely.

There are several types of reliefs from Inheritance Tax (IHT), one of which is IHT Business Relief. This can be a significant tax benefit for those with business interests, potentially offering either 50% or 100% relief from IHT on the value of business assets if certain criteria are met.

• 100% Business Relief can be claimed for a business, an interest in a business, or on shares in an unlisted company.

• 50% Business Relief is available for:

• Shares with more than 50% of the voting rights in a listed company.
• Land, buildings, or machinery owned by the deceased and used in a business they were involved with or controlled by.
• Land, buildings, or machinery used in a business and held in a trust benefiting from it.

This relief only applies if the deceased owned the business or asset for at least two years prior to their death.

However, there are limitations, for example, if the company primarily deals in securities, stocks, shares, land, buildings, or investments. In some situations, partial Business Relief might be possible.

Given its complexity, it is crucial to assess whether IHT Business Relief applies based on your specific circumstances.

The Inheritance Tax residence nil rate band (RNRB) is a transferable allowance for married couples and civil partners (per person) when their main residence is passed down to a direct descendent such as children or grandchildren after their death. 

The allowance increased to the present maximum level of £175,000 from 6 April 2020. The allowance is available to the deceased person’s children or grandchildren. Any unused portion of the RNRB can be transferred to a surviving spouse or partner. The RNRB is on top of the existing £325,000 Inheritance Tax nil-rate band.

The allowance is available to the deceased person's children or grandchildren. Taken together with the current Inheritance Tax limit of £325,000 this means that married couples and civil partners can pass on property worth up to £1 million, free of any Inheritance Tax liability, to their direct descendants. 

The transfer does not happen automatically and must be claimed from HMRC when the second spouse or civil partner dies. This is usually done by the executor making a claim to transfer the unused RNRB from the estate of the spouse or civil partner that died first. This transfer can also happen even if the first spouse or civil partner died before the RNRB was introduced on 6 April 2017.

There is a tapering of the RNRB for estates worth more than £2 million even where the family home is left to direct descendants. The additional threshold will be reduced by £1 for every £2 that the estate value exceeds the £2 million taper threshold. This can result in the full amount of the RNRB being tapered away. The RNRB maximum rate and the taper threshold are currently frozen until at least April 2028.
