Inheritance Tax changes underline importance of business succession planning

The 2024 Autumn Budget introduced significant changes to two of the key Inheritance Tax (IHT) reliefs with effect from 6 April 2026, meaning many more UK taxpayers will be brought into scope of IHT.  As such we are encouraging our clients and contacts to review their current and potential assets and plan now to minimise the tax impact in the future.

What’s changing?

Agricultural property relief (APR) and Business Property Relief (BPR) will change so that, rather than the current unlimited levels of relief on qualifying disposals, 100% relief will only be available on the first £1m of value, with anything beyond that only receiving 50% relief. Additionally, relief for Alternative Investment Market (AIM) shares will be restricted to 50%.  Business owners need to think carefully therefore before gifting shares.

While it will still be important to ensure that you can benefit from these important reliefs, those who had assumed that no IHT would be payable will have to take advice to consider how to mitigate the potential tax charge, particularly where their estate will not have sufficient liquidity to pay the tax.

Similarly, it was also announced that there would be changes to the inclusion of pensions in estates for IHT purposes. From 6 April 2027, any unused pension savings and death benefits may be included within the value of a person’s estate assessable for IHT. For many people, these changes to tax on assets could mean that their estate exceeds their nil rate band (NRB) for the first time. This will lead to more assets being susceptible to IHT.

Importance of planning

Just as a business plan is used to create, fund, run and expand an organisation, a strategy needs to be put in place to enable succession. In our experience, when a business is a key component of family wealth the owner usually has a strong desire to preserve it in one form or another. As such, planning ahead is a key element and is essential when considering passing on management and ownership to your children or other family members.

Around two-thirds of family business owners report a good understanding of the amount of estate taxes due upon their deaths, but about one in five have no estate planning at all. More than one in three junior generation family business members have no knowledge of their senior generation’s transfer plans.

The changes to Inheritance Tax and pension rules, along with the complexities of succession planning, highlight the importance of proactive estate and business planning. With careful preparation, you can navigate these challenges and ensure a smooth transition for both your wealth and your business.
