Inheritance Tax reform and how this impacts plans for succession

Inheritance tax (IHT) has long been a concern for family businesses, but changes to the way business and agricultural assets are taxed on death have prompted many business owners to re-examine their succession plans and consider whether existing arrangements remain fit for purpose. 

With 100% Agricultural Property Relief and Business Property Relief restricted to a combined £2.5m allowance per individual, many established family businesses – particularly those with valuable land, property or trading assets – may find that parts of their estate fall outside full relief for the first time. 

What matters most for family businesses is understanding how the rules have changed,  what risks these changes create, and what practical steps can be taken now to protect continuity and lasting value.

Why this matters for succession planning

For family businesses, the key concern is not simply the tax itself, but the timing of it. IHT is generally payable within six months of death. If a large bill arises and the business is asset rich but cash poor, successors could be forced to consider selling assets, taking on debt, or even selling the business itself to fund the tax bill. This is particularly relevant for multi generational businesses where ownership is intended to stay within the family, and for farming businesses where much of the value is tied up in land rather than income producing assets. Even when the business is profitable, a sudden tax liability can place strain on working capital at a critical moment.

Explore options early

Succession planning is rarely quick or simple, and options are often broader – and more tax efficient – when considered early. For example, lifetime gifting, restructuring ownership between family members, or reviewing the use of trusts may be worth exploring. Equally important is reviewing whether the business still qualifies for relief under the new rules, as changes in activity or structure over time can sometimes have unintended consequences.

Balance tax, control and fairness

Succession planning is about more than tax efficiency. Family businesses must also balance control, fairness among family members, and the business's long-term sustainability. IHT reforms have brought these conversations forward for many families. Questions such as who should inherit the business, how non involved family members should be provided for, and how decision making power should be passed on are central to any good plan, regardless of the tax environment. Taking a joined up approach that considers tax, legal and commercial implications together can help avoid piecemeal decisions that solve one problem but create another.

The importance of regular reviews

Many family businesses have succession plans that were put in place years ago, under very different tax and commercial conditions. The new IHT rules serve as a timely reminder that plans should be reviewed regularly to ensure they still reflect current law, business value and family circumstances. Even where no immediate changes are made, having up to date valuations, clear documentation and an agreed roadmap can make a significant difference if circumstances change suddenly.

Taking the next step

IHT reform has created understandable concern for family businesses, but it also presents an opportunity to revisit succession plans and strengthen them for the future. Early, informed planning can reduce uncertainty, protect the business, and provide greater confidence about what comes next.
