The Autumn Budget brought significant announcements in relation to inheritance tax (IHT) for landowners and business owners. While the existing nil-rate band and residential nil-rate band will remain unchanged, important reliefs for business property and agricultural property will be restricted from 6 April 2026. The inheritance of unused pension funds at death will also be brought within the scope of IHT.
Summary
IHT rate bands
IHT is a capital tax paid on the value of an estate on death and on certain chargeable lifetime gifts. The current rate of IHT is 40%.
An estate valued up to the nil-rate band (NRB) of £325,000 can be inherited without IHT. Any unused NRB of an individual can also be passed to their surviving spouse or civil partner. A further residential nil-rate band (RNRB) of up to £175,000 is available to reduce the value of an estate if a family home is left to direct descendants. Like the NRB, an amount of up to 100% of the unused RNRB can be passed on to a surviving spouse. A potential combined NRB and RNRB of up to £1m may therefore be available for a married couple whose joint estate is worth £2 million or less.
The Chancellor announced that the current NRB and RNRB will not change and has also frozen them at current thresholds for a further two years until 5 April 2030.
Business and agricultural property relief
Current rules allow relief from IHT for the value of trading business assets or agricultural land and property gifted during lifetime or held at the time of death. Broadly speaking, 100% business property relief (BPR) is available for a trading business, or an interest in a business, and unlisted shares in a trading company.
A 50% relief applies to some other forms of business assets, such as assets used by a trading business.
100% agricultural property relief (APR) is available for land or pasture used to grow crops or rear farm animals as well as associated property such as farmhouses and cottages. Relief can be restricted to 50% depending on the asset and tenancy arrangements.
Qualifying Alternative Investment Market (AIM) shares have historically qualified for 100% BPR, when held for more than 2 years.
Changes introduced
From 6 April 2026, the availability of BPR and APR at 100% will be limited to a total allowance of £1 million. The balance of qualifying assets will be eligible for relief at 50%. The rate of 50% applying to certain business and agricultural property will remain unchanged.
This new allowance will apply to the combined value of business property or agricultural property and will cover transfers during lifetime and the value of property in a death estate.
For example, the allowance could be divided across £750,000 of property qualifying for BPR and £250,000 of property qualifying for APR.
If the total value of the qualifying property to which 100% relief applies is more than £1 million, the allowance will be applied proportionately across the qualifying property. For example, if there was agricultural property of £6 million and business property of £4 million, the allowances for the agricultural property and the business property will be £600,000 and £400,000 respectively.
Assets automatically receiving 50% relief will not use up the allowance and any unused allowance will not be transferable between spouses and civil partners.
AIM shares will qualify for relief at 50%.
Anti-forestalling measures will be introduced in relation to lifetime transfers made on or after 30 October 2024 where the transferor passes away on or after 6 April 2026, meaning the £1 million limit could apply to those gifts.
The £1 million allowance also applies to trusts. Trustees of most trusts are liable to an IHT charge of up to 6% every ten years on the value of property held in a trust. There is also an exit charge when property leaves the trust. The £1 million allowance will apply to the combined value of property qualifying for BPR and APR within the trust, on each ten-year anniversary charge and exit charge. A consultation is expected in early 2025 covering the detailed application of these changes for property held in trust.
Settlors may have set up more than one trust comprising qualifying business or agricultural property before 30 October 2024, each trust would have a £1 million allowance for 100% relief from April 2026. The Government intends to introduce rules to ensure that the allowance is divided between these trusts where a settlor sets up multiple trusts on or after 30 October 2024.
Another update to IHT is that the Government will introduce legislation to extend the existing scope of APR from 6 April 2025 to land managed under an environmental agreement with, or on behalf of, the UK Government, devolved governments, public bodies, local authorities or approved responsible bodies.
Inherited pensions
Currently, the value of most pensions is outside the scope of IHT. From April 2027, the Government will bring unused pension funds and death benefits payable from a pension into an estate for IHT purposes.
Our comment
While changes to BPR and APR were anticipated, the precise form of any changes was uncertain and did not feature in the Labour manifesto. Amid concerns that the relief could be removed entirely, it is welcome to see commitment to maintaining the relief in some form.
These changes will have a significant impact for the owners of private businesses and agricultural assets, as well as their families. Careful thought will now need to be given to how these businesses can be continued by the next generation, as well as how families will be able to meet the IHT liabilities they are now exposed to.
As an example, the estate of a qualifying trading business owner with unlisted shares valued at £11m would now have a potential exposure to IHT of £2m, potentially without other liquid assets to pay it. This could call the long-term viability of some succession plans into question, particularly if family members are faced with a decision of selling the business to settle an IHT liability.
Understanding your IHT exposure is therefore crucial, particularly if your estate includes high value business assets, agricultural land or an inherited pension fund.
What may have previously been exempt or covered by 100% relief, may now be chargeable and be exposed to IHT at 40%.
