Inheritance Tax Reliefs for Farms & Family Businesses: What’s Changing in 2026?

From 6 April 2026, the UK government will introduce major changes to Inheritance Tax (IHT), significantly altering how Agricultural Property Relief (APR) and Business Property Relief (BPR) will work.

If you own land or a business, now is the time to act, as these reforms are set to reshape how family farms and small businesses are passed down to the next generation.

From the 1970s, the UK’s IHT system has allowed genuinely agricultural land and family businesses to pass largely IHT free under two reliefs APR and BPR. Although these reliefs helped preserve thousands of small businesses and family farms across the UK, over time, cracks began to show. Critics pointed out that these reliefs allowed a few very wealthy owners to stash immense value in farmland or unquoted shares, thereby avoiding tax. One commentator noted that farmland "the best way to leave £100 million to your kids", illustrating how some of the very richest inherited farmland is tax free. With growing public concern around fairness and the need for fiscal responsibility, the government has now announced major changes that will reshape how inherited farms and businesses are taxed from 2026, in the Autumn Budget 2024.

The reforms mainly include capping APR and BPR at £1 million per individual for full relief. Assets above this limit will face partial relief, reducing longstanding tax exemptions for large estates. Key changes include revised share treatment, tighter trust rules, and a non-transferable cap, signalling a major shift in estate and succession planning for farming families and business owners.

We will discuss these changes in detail later in this article, also highlighting the government’s intent, affected parties and how landowners, business owners, and their advisers can prepare.

How APR & BPR Work?

For decades, APR and BPR have played a vital role in protecting family-run farms and businesses. These reliefs were introduced in the 1970s and 1980s, when policymakers decided that requiring a family to sell their farm or business to pay tax on death would be unfair. These reliefs ensure that a farm or family business could continue trading after the owner’s death. Over the years, these rules became very generous and by the mid-1990s almost all qualifying farm and business assets received 100% IHT relief, allowing them to be passed on tax-free.

APR applies to land and property used for agricultural purposes, such as farmland, pasture, and associated buildings like barns, farm cottages, and even farmhouses, provided they are of a character appropriate to the land and used in connection with the farming trade.

The relief covers the agricultural value of the property, that is, the value it holds assuming it can only be used for agriculture, which is typically lower than open market value. If the owner has actively farmed the land themselves for at least two years or has owned the land and let it under a qualifying tenancy for at least seven years, APR at 100% can apply. In some older tenancy arrangements, the relief is reduced to 50%.

BPR, on the other hand, extends to property used in a qualifying trading business. This includes shares in unlisted trading companies, land and buildings used in a business, and machinery or plant used for business purposes.

To qualify, the asset must have been owned by the individual for at least two years and must be used wholly or mainly for a trading business, not one that deals mainly in securities, investments, or land. BPR is available at 100% for assets like unquoted shares and property used in a business owned by a sole trader or partnership. In other cases, such as land used in a company controlled by the individual but not owned by the company itself, BPR may apply at a reduced rate of 50%.

These reliefs are designed to operate automatically where all conditions are met, so no formal claim is necessary, but in practice, HMRC scrutinises compliance closely.

The valuation of the asset, the nature of its use, and the continuity of occupation or business activity are all factors that can affect whether relief is granted.

What Is Changing: The New Inheritance Tax Rules

The government’s plan announced in the Autumn Budget on 30 October 2024 does not abolish APR/BPR outright but substantially narrows their scope from 6 April 2026. The major changes are:

1. The New £1 Million Cap on 100% Relief

From 6 April 2026, only the first £1 million of combined qualifying agricultural and business property in an estate will get the full 100% relief. Any value above £1 million in total value will qualify only for only 50% relief. In effect, after the first £1m is sheltered, any excess is effectively taxed at 20% (half the normal 40% IHT rate).

2. Reduced Relief on Shares

Not all shares benefit equally under the new relief structure:

• Unlisted or AIM-listed Shares
  These will not qualify for the £1 million full-relief cap. Instead, only 50% relief applies, regardless of value.
• Foreign-Listed Shares
  Shares listed on unrecognised foreign exchanges will also receive only 50% relief.
• Other Unlisted Shares
  Retain their 100% BPR eligibility, provided the total does not exceed the £1 million cap.
• Quoted Shares with Control 
  Continue to qualify for 50% BPR, unchanged under the new rules.

3. Trusts & Anti-Fragmentation Rules

Trusts are impacted based on their date of establishment:

• For trusts settled before 30 October 2024, each gets a separate £1 million cap on qualifying APR and BPR assets
• For trusts settled on or after 30 October 2024, they will share a single £1 million cap across all trusts created by the same settlor, due to new anti-fragmentation rules

This distinction creates a clear incentive for pre-30 October 2024 trust planning. It also affects share valuation rules and limits future flexibility in estate structuring.

Transitional Opportunity: Trusts making qualifying distributions before 6 April 2026 will still benefit from full 100% relief, offering a short-term window for strategic planning. However, Capital Gains Tax and other liabilities should be carefully assessed before making such moves.

4. Impact on Spouses

Unlike the standard nil-rate band, the £1 million APR/BPR allowance cannot be transferred between spouses. However, each individual has their own £1 million cap, meaning a couple can shelter up to £2 million at 100% relief.

5. Option to Pay IHT in Instalments

To ease liquidity issues, the government has extended the option to pay IHT liabilities relating to agricultural and business property in equal annual instalments over 10 years. This helps families avoid forced asset sales, particularly farms or private businesses, when facing large IHT bills. While it does not reduce the tax owed, it spreads payments over time, reducing the financial burden.

6. Policy Intent & Economic Impact

These reforms aim to target wealthier estates, particularly those with extensive business and agricultural holdings. Data from HMRC indicates:

• Roughly 3,000 estates annually will be unaffected
• Around 2,000 estates will pay more, including 500 farming estates and 1,000 with significant unlisted shareholdings
• The median APR claim in 2021/22 was £486,000, and 75% of estates claiming APR were under the new £1 million cap

According to the Office for Budget Responsibility, the reforms are expected to raise £520 million annually by 2029/30, although reliefs will still cost the Treasury about £1.8 billion per year. The Institute for Fiscal Studies notes that couples could still pass on £3–4 million tax-free, including nil-rate bands, under the new system, confirming that IHT burdens will remain concentrated on the largest estates.

7. Relationship Between APR & BPR

A key rule in inheritance tax planning is that APR and BPR cannot both be claimed on the same asset. If a property meets the conditions for both types of relief, APR takes priority over BPR. This rule matters most in estates that include a mix of agricultural and business assets.

However, in practice, there are situations, especially involving shares in farming companies where it may be simpler to apply BPR to the full value of the shares, if the tax outcome would be the same. This is often done for administrative ease, even though technically APR should apply first.

Additionally, parts of a property that do not qualify for APR might still qualify for BPR, as long as the conditions for BPR are met. This means it is possible for different elements of the same asset to receive different types of relief, depending on their use and characteristics.

With the post 2026 reforms introducing a combined £1 million cap on 100% IHT relief, the distinction between APR and BPR is less important for the first £1 million of qualifying assets. What matters more is ensuring that assets meet at least one of the qualifying conditions, so that relief can be claimed at all. Beyond the £1 million cap, a 50% relief rate applies regardless of whether the asset originally qualified under APR or BPR. This makes the tax calculation itself simpler, but the process of proving eligibility for either relief still requires careful analysis.

Why the Change?

The Labour government, under Prime Minister Sir Keir Starmer and Chancellor Rachel Reeves, highlighted that the reform is about asking those with “broadest shoulders” to bear a fairer share of tax. According to the Treasury, a small group of very wealthy individuals had been exploiting generous IHT reliefs to pass on farmland and businesses tax-free sometimes without ever working on the land themselves. With farmland values soaring, it had become, a tax shelter as per critics.

By capping APR/BPR at £1 million per person, the government hopes to make the system more equitable. The Institute for Fiscal Studies estimates this will raise around £520 million annually, a welcome boost for public finances during tight spending and borrowing conditions.

Who’s Affected & How?

For many families, this is not just a tax change, it is a deeply personal issue that reshapes how farms and businesses are passed down.

• Family Farmers
  While small farms are untouched, medium to large farms could face hefty tax bills. Some fear they will be forced to sell land or equipment to pay up. Farming is often asset-rich but cash-poor, and organisations like the Country Land and Business Association (CLA) warn the policy could lead to parts of family farms being sold off damaging rural livelihoods and mental health.
• Small Business Owners
  Family-run firms outside farming also face pressure. If business assets exceed £1 million, heirs might need to sell shares or parts of the business just to pay the tax, risking its survival. Some worry this could even lead to a “double hit” if capital gains tax is also triggered.
• Advisers & Estate Planners
  Tax professionals say the rules will bring complexity, confusion, and cost. They are already seeing a rush of clients updating wills, gifting assets early, or setting up trusts. However, new restrictions mean people can’t simply create multiple trusts to dodge the cap.
• Land & Financial Markets
  Analysts expect short-term disruption, with potential land sales flooding the market. Over time, the reform may slightly ease land prices, opening opportunities for new farmers. But some fear a chilling effect on rural investment as owners rethink spending in fear of future taxes.

While the changes may not affect everyone, they mark the end of an era, one where farm inheritance was often tax-free. Now, careful planning is more important than ever for families who want to keep their land and businesses intact for the next generation.

Economic & Political Impact

Economists back the logic, though some say the cap does not go far enough. The Institute for Government, for instance, argued that abolishing the reliefs altogether would be the fairest option. Still, the move brings the UK more in line with international norms. Most developed countries don’t offer such generous farmland exemptions, and only a handful offer any relief at all.

Politically, the change is tricky. Labour had previously promised to protect APR during the election campaign. That U-turn has angered many in rural communities. Ministers now stress that small farms, those under £1 million in value will not be affected, and a married couple can still pass on up to £3 million tax-free thanks to other allowances.

Reactions from Farmers, Advisers & Politicians

The response to the APR and BPR changes has been swift and emotional, especially from the farming community. Groups like the National Farmers’ Union (NFU) have called the reforms a “disaster” for family farms, warning they could drive up food prices and threaten the future of rural life.

In Wales and Northern Ireland, hundreds of farmers have protested, with some saying they may need to sell land or worse just to cover tax bills. Mental health charities report a rise in distress, with some farmers fearing there is no future left for the next generation.

The Country Land and Business Association (CLA) and many farmers see this as a “tax on farming,” arguing it shows how little the government understands rural business. Politicians, including Conservative MPs, Scottish Tories, and the DUP, have spoken out, calling it a threat to local economies and small family farms. Even some supermarkets have voiced concern, worried the changes could hit domestic food production.

Advisers and tax experts are also raising the alarm. Bodies like the ICAEW and CIOT are calling for transitional relief and pointing out issues like non-transferable allowances and higher admin costs. Families are being urged to review wills and trusts now, as planning has suddenly become much more complex.

Meanwhile, the media highlight a contrast in number as the government says only 500 estates will be affected, but farming groups insist thousands of families could lose out. Editorials and blogs have shown a deep divide in opinion. Some support the changes, arguing they promote fairness by reducing generous tax breaks that mostly benefit the wealthy. Others strongly criticise the move, describing it as a “tax raid” on farmers.

Expert’s Opinion on the New Rules

Experts say the upcoming changes to APR and BPR will have a big impact on how landowners plan. Many expect a rush in succession planning, as older owners may try to pass on assets earlier, though that could mean giving up control or facing other tax risks. Some may restructure ownership or use tools like insurance trusts or corporate share purchases to help cover tax bills. The option to delay inheritance tax payments for 10 years, interest-free, could ease short-term cash pressures.

Professional bodies like the ICAEW are suggesting ways to soften the blow, such as tapered relief or more time for active farmers over 65 who can’t easily gift land. Others argue the £1 million cap should rise with inflation and be shared between spouses.

Trusts are under the spotlight too. Since the new rules mean trusts will share in the cap, experts are urging families to review all existing trusts and be cautious about creating new ones after 30 October 2024, as more complex rules may apply.

Some say these reforms might help new farmers by making land more affordable, as the tax perks for holding land as a wealth store shrink. But there are also worries: cutting tax relief could make landowners less likely to invest in farms or rural businesses.

Key Takeaways

The upcoming changes aim to strike a better balance by supporting the genuine family enterprises, while also limiting high-value estates from using the system as a tax shelter.

Landowners, farmers, and business proprietors across the UK should be aware of these changes. While the reforms are designed to modernise and tighten the inheritance tax system, they also bring complexity, urgency, and significant financial risk.

What is particularly important is the tight timeline. Many affected individuals still believe they have until April 2026 to act, but some of the most crucial changes take effect as early as 30 October 2024. From that point on, the ability to make the most of certain reliefs, especially for those using trusts or making lifetime transfers, will be significantly reduced.

It is important to note that these reforms are not just technical updates; they carry real financial consequences. Misunderstanding or delaying action could lead to significantly higher inheritance tax bills, a loss of generational wealth, or difficult choices for heirs who may face cash flow problems at a critical time.
