Selling farmland after the 2026 inheritance-tax changes: land, tax and timing

For as long as most farming families can remember, land could pass from one generation to the next without inheritance tax swallowing it. The reliefs were generous enough that the farm, in practice, moved down the line more or less whole. That settled assumption, quietly relied on for decades, no longer holds in the same way. From 6 April 2026, the way agricultural and business property are relieved from inheritance tax has been reformed, and a great many families are now working out what it means for them.

Before we go a step further, one thing has to be said plainly and it runs through everything below. This is general information, not tax or financial advice. The detail is complex. It turns on the specifics of each estate, and the rules are still being refined. Nothing on this page should be acted on without proper professional tax and legal advice taken on your own circumstances. We are a land promoter, not your adviser, and we would not want to be read as either.

What has actually changed

The reform concerns two long-standing reliefs. Agricultural Property Relief, usually shortened to APR, and Business Property Relief, or BPR. Between them these are what allowed qualifying farmland, farm assets and trading businesses to pass at death with much of their value taken outside the inheritance-tax net.

At a general level, the shape of the change is this. From 6 April 2026, full 100 per cent relief is retained on the first £1 million of combined qualifying agricultural and business property. Above that threshold, the relief is reduced to 50 per cent, which works out as an effective inheritance-tax rate of 20 per cent on the value over the £1 million. The House of Commons Library set this out in its briefing on the reform, numbered CBP-10181, and firms including Saffery, Weightmans and Strutt & Parker have published their own readings of how it is expected to work in practice.

Those are the broad strokes, and broad strokes are all they should be taken as. How the £1 million allowance interacts with a marriage, with trusts, with lifetime gifts and with the different classes of asset a working farm holds is intricate, and it is exactly the sort of thing that a good agricultural accountant or solicitor exists to untangle. The numbers that matter are the ones worked out on your estate, not the ones in an article.

Why the whole-estate picture now matters more

What the change really does is sharpen a question that was always there but was easy to leave alone. When the farm passed down largely untaxed, there was rarely much pressure to look hard at what any single part of it was worth in any use other than farming. Now that a portion of value above the threshold may carry a real liability, the composition of an estate matters in a way it did not before.

This is where land with development potential enters the picture, and it needs handling carefully. A field on the edge of a village may be worth one thing as pasture and quite another if it could one day carry homes. That difference does not create a tax bill on its own, but it changes the size and shape of the estate a family is planning around, and therefore the conversation they should be having with their advisers. Some families will conclude the right course is to hold and pass everything down as it stands. Others will look at the numbers and decide something different. There is no general right answer here, and anyone who offers you one without knowing your estate is not worth listening to.

The point we would make, and it is the only one we are qualified to make, is that land is rarely just a site. It sits inside a family’s wider position: the working business, the home, the other assets, the people who will inherit and what they actually want. Good decisions come from seeing that whole picture, with the right professionals in the room, rather than from treating one field in isolation.

Where a land read fits in

None of this is a reason to rush, and it is certainly not a reason to sell. Reforms like this tend to produce a lot of noise and a lot of people telling landowners what they ought to do. We would rather do the opposite.

What can help is better information. Knowing whether a piece of land has any real development potential, and roughly what that might mean, is one of the inputs a family and its advisers need when they sit down to plan. It is often the missing one, because it takes local planning knowledge to judge and is easy to guess at wrongly in either direction.

That is the narrow, honest place we fit. A first read of a site’s potential, with no obligation and nothing to sign, that tells you what you are actually holding. It is information to take into the conversations that matter, alongside your accountant and your solicitor, not a substitute for them. The changes are real and the questions they raise deserve proper answers. We would only ever want to help you ask them from a clearer starting point.
