The £2.5m cap’s effect on generational handovers

The original purpose of business relief was pretty straightforward: it was designed to prevent family businesses from being broken up or sold purely to meet an inheritance tax liability. But things are changing, writes Sean Bannister, head of tax at Edwin Coe.

For decades, business relief has underpinned how ownership passes between generations, allowing long-term stewardship rather than forced exits.

But the latest changes to business relief are fundamentally shifting away from that position, and will continue to do so, affecting decisions across family-owned businesses.

The introduction of the £2.5m ($3.4m) cap does not simply encourage better planning but forces it, often earlier than intended and sometimes under significant pressure. This is not just affecting large businesses like the much-publicised JCB family, but playing out in lots of the conversations we are having with small and medium-sized businesses.

Succession has traditionally been a long-term process. Families would phase in the next generation over time, aligning ownership with experience, responsibility and readiness. That approach is becoming harder to sustain. The window for planning is narrowing, and decisions that were expected to play out over decades are now having to be made in a much shorter timeframe. A sense of fear combined with changing policies is making planning look very different.

We are seeing a clear increase in lifetime gifting and earlier transfers of shares, in some cases well ahead of when families would ideally choose to make those moves. For some, this is manageable. But for others, it creates tension between tax efficiency and commercial reality – and personal feeling. A family business can be a highly emotional thing.

Let us take the example of a family-owned business that had planned a gradual 10-year transition of ownership. That timetable could now been compressed into closer to two years, with shares being transferred to the next generation before they are fully established in leadership roles.

We might have a multi-entity group where the family had relied heavily on business relief as the primary mechanism for passing on wealth. With that assumption no longer holding water in the same way, attention will shift towards partial disposals and bringing in external capital to manage future exposure.

We have also seen the conversation change from transferring family businesses to sale. Clients are now starting to comment that it is much easier to plan with cash, and create a succession structure with what could be termed a ‘clean start’, than navigate the complexities of transferring a family company in short order.

A noticeable shift to complexity

Entire business groups have been built on the expectation that business relief would continue to provide a stable framework for succession. That has now been removed, resulting in a marked adjustment in approach.

There is also a noticeable shift back towards more complex structuring. Trusts and layered ownership arrangements were expected by some to become less relevant over time. Instead, the tightening of relief is pushing families back in this direction, with a belief that it will protect them from both external and internal threats. Where straightforward planning is no longer sufficient, more sophisticated structures are being revisited to balance control, tax efficiency and flexibility.

What is striking is how little attention this has received compared to other areas of reform. Much of the public debate has focused on agricultural relief, which is important but applies to a narrower group – around 500 according to the Treasury, though industry groups put the figure at 70,000. The real number is likely to be somewhere in between.

The changes to business relief affect a far broader base of family-owned trading businesses, many of which are central to employment and economic activity across the UK. The impact is wider, and affects innovation, growth, and capital.

The commercial consequences are also worth considering. Where succession becomes compressed or reactive, the risk of disruption increases. Leadership transitions may happen before successors are fully ready, and strategic decisions may be driven by tax considerations rather than business need. In some cases, families may feel they have little choice but to explore a sale, even where there is a strong desire to retain long-term ownership.

This is why the £2.5m cap feels less like a technical adjustment and more like a structural change. It is altering the way ownership moves between generations, shifting the balance away from gradual, planned transitions towards earlier and more immediate action.

Business relief was introduced to avoid precisely the kind of pressure that is now beginning to re-emerge. While the current regime does not remove relief entirely, it changes its effectiveness in a way that brings those pressures back into play.

For advisers and their clients, the focus now is on adapting to that reality. Planning is still possible, but it requires earlier engagement, greater flexibility and, in many cases, a willingness to revisit structures that were previously thought to be less relevant. The broader question is whether this represents a deliberate policy shift or an unintended consequence of tightening the rules. Either way, the direction of travel is abundantly clear. Succession in family businesses is becoming faster, more complex and, at times, more uncertain than it has been for a generation – which I am not sure was the intended outcome.
