The April 2026 IHT Changes: What They Mean for Farming Families — and Why Collaboration Could Be the Answer

For decades, farming families across the UK have been able to pass their land and businesses from one generation to the next without facing a crippling inheritance tax bill. Agricultural Property Relief (APR) and Business Property Relief (BPR) have been the bedrock of farm succession planning, offering up to 100% relief with no upper limit.

That is about to change.

From 6 April 2026, the rules are being overhauled in the most significant shake-up to agricultural inheritance tax in a generation. If you farm in Warwickshire or the surrounding area and haven't yet reviewed your plans, now is the time to act.

What's Actually Changing?

Under the current rules, qualifying agricultural and business assets can be passed on completely free of inheritance tax, regardless of value. From 6 April, a cap is being introduced:

• 100% relief will apply to the first £2.5 million of combined APR and BPR qualifying assets per individual
• Assets above £2.5 million will receive only 50% relief, meaning an effective inheritance tax rate of 20% applies to the excess
• Married couples and civil partners can combine their allowances, giving a potential joint threshold of £5 million — but this does not apply to cohabiting couples
• The tax, where it arises, can be paid in up to 10 annual interest-free instalments

The government raised the threshold from the original £1 million proposal following intense pressure from farming organisations and backbench MPs, with the NFU's 'Stop the Family Farm Tax' campaign attracting over 270,000 signatures. While the concession is welcome, the changes still represent a substantial departure from the unlimited relief many farming families have long relied upon.

Who Is Affected?

HMRC estimates that around 185 estates claiming APR will face higher tax bills in 2026-27. That may sound like a small number but the impact on individual families can be significant.

Consider a typical arable farm in the Midlands. Land values have risen sharply in recent years, and a farm that seemed modest in acreage could easily carry a market value well above £2.5 million. For a sole landowner who is not married, or whose assets are not structured efficiently, the exposure could be considerable.

It's also worth remembering that APR applies only to genuine agricultural property in active farming use. Land used for solar panels, horse grazing or paddocks may not qualify, or may qualify only partially. If you've been assuming everything on your holding will attract full relief, it's worth checking that assumption carefully.

The Urgency of Acting Now

One of the less-discussed aspects of these reforms is how they interact with lifetime gifts. If you gift qualifying assets before 6 April 2026, the old rules apply at the time of the gift. However, if you die within seven years of making that gift after 6 April 2026, the new £2.5 million cap will apply retrospectively when calculating the inheritance tax on the failed transfer.

This means the window to plan under the old rules is rapidly closing, and decisions made now, or avoided now, will have lasting consequences.

How Collaborative Farming Can Help

At Windmill Farming, we work with landowners across Warwickshire through a range of farming arrangements - Contract Farming Agreements, Farm Business Tenancies, Hybrid CFAs, Stubble-to-Stubble agreements, and True Joint Ventures. While these structures are primarily about getting the best out of your land operationally, they also have real relevance to how your estate is organised and valued.

Here's why:

Keeping the farm actively trading matters. BPR, which can apply alongside APR, is only available on actively trading businesses. A well-structured farming agreement helps ensure your holding is treated as a genuine trading enterprise rather than an investment asset, which can affect how relief is calculated.

Shared costs, better margins. The practical pressure that inheritance tax changes bring often forces difficult decisions: sell land to pay a tax bill, or take on debt. Collaborative farming arrangements can improve the profitability and resilience of your farm, making it easier to absorb unexpected financial demands without breaking up what you've built.

Thinking ahead on succession. Many of the landowners we work with are thinking about the next generation. A well-considered farming arrangement can be a useful part of a broader succession strategy, keeping the land working, preserving its agricultural character, and demonstrating active use to HMRC when relief is eventually claimed.

A Note of Caution

The rules here are complex, and this article is not legal or tax advice. The interaction between APR, BPR, wills, trusts, pension planning and the new rules is something that genuinely requires specialist input. We would always recommend speaking with an accredited agricultural solicitor and a tax adviser who understands the farming sector.

What we can say is that the farming arrangements we offer at Windmill Farming are increasingly being considered not just as operational tools, but as part of a broader, forward-thinking approach to land management and business structure.
