From 6 April 2026, the UK government has fundamentally reshaped Agricultural Property Relief (APR) and Business Property Relief (BPR), two reliefs that have long allowed farmland, working farms, trading businesses and certain investment structures to pass to the next generation free of Inheritance Tax (IHT). These reforms, first announced by Chancellor Rachel Reeves in the Autumn Budget of 30 October 2024, represent the most significant change to IHT relief for business and property owners in three decades. For property investors, landed estate owners and family business owners, understanding the new rules is now essential to protect wealth and plan succession effectively.
What Has Changed
Previously, qualifying agricultural and business assets could attract unlimited 100% relief from IHT, meaning many estates passed to heirs without any tax charge at all. That position has now changed substantially.
- A new combined allowance of £2.5 million applies per person to the total value of assets qualifying for both APR and BPR.
- Qualifying assets within this £2.5 million threshold continue to receive 100% relief, so no IHT is payable on that portion.
- Assets above the £2.5 million threshold now receive only 50% relief, producing an effective IHT rate of 20% on the excess, rather than the previous 0%.
- The allowance is transferable between spouses and civil partners in a similar way to the nil rate band, so a married couple could shelter a combined £5 million if planning and Wills are structured correctly.
- Shares in AIM listed companies and those qualifying under the Enterprise Investment Scheme (EIS) now receive a flat 50% relief regardless of value, and these do not use up the £2.5 million allowance.
- Anti forestalling rules mean lifetime transfers made after 30 October 2024 already fall under the new regime, so backdated planning cannot avoid the changes.
- The £2.5 million threshold is frozen until April 2031 and will then rise annually in line with inflation.
- Assets held in trust are also affected, with trusts benefiting from their own £2.5 million allowance, though tax treatment varies depending on when the trust was established.
Impact on Property Investors and Landed Estates
For property investors who hold farmland, mixed use estates or trading premises through family companies or partnerships, the practical effect is a much narrower window of tax free succession. Where an estate or portfolio exceeds the combined £2.5 million allowance, the excess will now attract a 20% charge on death, a liability that many succession plans never anticipated.
APR itself is restricted to the agricultural value of land, which HMRC often assesses at between 60% and 70% of open market value for farmhouses, though there is no fixed standard discount and each case is assessed individually. This means the gap between agricultural value and market value becomes more important than ever, since only the agricultural element benefits from APR, while any development or hope value typically falls outside the relief altogether unless BPR can be claimed instead. Investors holding land with development potential should expect closer HMRC scrutiny of valuations under the new rules.
Dual relief properties, such as stud farms, mixed agricultural and commercial estates, or diversified rural businesses, must now consider how the £2.5 million threshold applies proportionally across both APR and BPR claims. Reviewing ownership structures, such as splitting ownership between family members or restructuring partnerships and companies, may help maximise the number of £2.5 million allowances available across a family group.
Why Structuring and Valuation Now Matter More
Since unlimited relief is gone, the way property and business assets are owned, valued and passed on has a direct bearing on the tax bill a family will face. Business owners with qualifying assets above £2.5 million may face liquidity pressure, since meeting an unexpected tax liability could require selling shares, land or even parts of the business itself. This makes robust, up to date valuations essential, both to quantify exposure and to support figures reported to HMRC.
Trusts also require fresh attention. Creating a trust does not automatically avoid IHT, since trusts are themselves subject to periodic charges every ten years, and the new £2.5 million allowance interacts with these charges in ways that require specialist review. Existing Wills, partnership agreements, shareholder agreements and lifetime gifting strategies should all be revisited to ensure they reflect the post April 2026 rules and make full use of transferable allowances between spouses.
Practical Steps for Property Investors
Property investors and landed estate owners should consider the following actions ahead of, or in response to, the new regime.
- Commission an up to date, defensible valuation of agricultural and business assets to establish current IHT exposure.
- Review ownership structures, including partnerships, companies and joint interests, to maximise available £2.5 million allowances across the family.
- Update Wills to ensure both spouses’ allowances are used, since the threshold is transferable but only if documentation reflects this.
- Reassess trusts already holding qualifying assets, given the interaction between the new allowance and ten yearly trust charges.
- Consider lifetime transfers carefully, noting that transfers made after 30 October 2024 already fall under the new anti forestalling rules and that the seven year rule for potentially exempt transfers still applies.
- Explore insurance backed solutions to fund a future IHT liability without forcing a sale of land or business assets.
- Keep clear, contemporaneous evidence of trading activity where BPR is being claimed, since passive or investment heavy activities may not qualify.
Accounting and Tax Planning Implications
From an accounting and taxation perspective, these changes turn APR and BPR planning into an ongoing compliance exercise rather than a one off arrangement. Accurate record keeping around business activity, agricultural use, valuations and the timing of transfers will directly determine how much relief a family can retain.
Given that the £2.5 million allowance is frozen until 2031, inflation will steadily erode its real value, meaning more estates will be pulled into the 20% charge over time even without any change in family wealth. Coordinated tax, legal and valuation advice, delivered together rather than in silos, is now the most effective way to manage exposure and preserve intergenerational wealth.

Frequently Asked Questions:
What is the new APR and BPR allowance from April 2026?
A combined £2.5 million allowance now applies per person to agricultural and business assets, with 100% relief up to that amount and 50% relief above it.
Can the allowance be shared between spouses?
Yes, any unused portion of the £2.5 million allowance can be transferred to a surviving spouse or civil partner, giving couples a potential combined allowance of up to £5 million, provided Wills are updated accordingly.
Do AIM shares still qualify for full relief?
No, AIM listed and EIS qualifying shares now receive a flat 50% relief regardless of value and do not use up the £2.5 million allowance.
Are lifetime gifts made before the rules change protected?
No, anti forestalling rules mean any lifetime transfers made after 30 October 2024 already fall under the new regime.
How is agricultural value different from market value?
Agricultural value reflects a property’s worth assuming it can only be used for farming, and HMRC often assesses this at 60% to 70% of open market value, though there is no fixed standard percentage.
Will the £2.5 million threshold increase over time?
The threshold is frozen until April 2031 and will then rise annually in line with inflation.
