This one is going to hit hard, and the people writing the rules in the Treasury know it. From 6 April 2026, Agricultural Property Relief and Business Property Relief are capped at a combined £2.5 million per person, with only 50% relief on anything above. For decades, these reliefs have been the quiet backbone of the family business and family farm. They allowed a working life of building something to be passed on, intact, to the next generation. Labour has just put a sword through that.
Make no mistake about the scale of what has changed. A family farm worth £4 million — not a vast estate, just a modest working dairy or arable holding in any English county — would, on the death of the owner, see roughly £300,000 of inheritance tax fall due on the portion above the cap. The next generation will not have £300,000 in cash. They will have machinery, livestock, land and a mortgage. The only way to pay the bill is to sell the farm — or sell enough of it that the rest is no longer viable.
This Is a Policy Designed to Force Sales
Let us not pretend Labour stumbled into this. The £2.5m cap was chosen deliberately. It was chosen because it sits exactly at the threshold where modest, productive, multi-generational businesses become "tax exposed." A clogs-to-clogs cycle of selling up every time a generation dies is now a feature of the system, not a bug. That is not tax policy. That is industrial policy in reverse.
And it is not just farms. The same cap hits the engineering firm in a market town, the printer that's been in three generations, the small hotel run by a couple in their seventies whose daughter is about to take it on. Every one of these businesses employs people, pays into the local economy, contributes to a sense that the area has its own character. Every one of them is now living on borrowed time.
The Judicial Review Is Coming
The farming community has not gone quietly. A judicial review has been launched challenging the legality of the changes. The argument is straightforward: the policy was rushed, the consultation was inadequate, and the impact assessment was either wrong or deliberately obscured. Whatever the court rules, the political message has already been sent — and the farmers, the family firms and the rural economy have all received it.
They received it at the polls earlier this month. Look at the swing in rural England and the eastern counties on 7 May. Reform UK took county after county where farming and small business are the backbone of the economy. That was not an accident. That was the IHT raid being repaid at the ballot box.
The Treasury's Own Forecast Is a Confession
The Treasury reckons it will raise about £500 million a year from this measure once fully in place. Set that against the damage. Set it against the loss of productive capacity, the depressed prices when forced sales hit thin local markets, the rural depopulation that follows when each generation leaves, and the secondary impact on suppliers, contractors and rural high streets. £500 million is a rounding error in the welfare bill. It is not worth the social damage of breaking the family business model that built the British countryside.
And what is the money for? It is for asylum hotels. For ballooning departmental budgets. For a state that grows every quarter and delivers less every year. The British family business is being sacrificed to fund the British state's inability to control its own spending.
What Reform UK Would Do
Reform UK will reverse the £2.5m cap and restore full Agricultural Property Relief and Business Property Relief at the first available fiscal event. We will go further. We will end the bias in the tax system that treats inherited wealth differently depending on how it was earned. A family that built a business over forty years should not pay more on its death than a family that received an asset windfall through the financial markets. The system should reward building. It should reward continuity. It should reward the kind of long-term, intergenerational investment that this country desperately needs more of.
Labour are taxing the people who feed us, the people who employ our neighbours, and the people who pass on more than they ever took. We will undo it. And the country will remember which party stood by the family firm.
