Inheritance Tax Changes in 2026: How the New APR & BPR Caps Affect Business Owners
Inheritance Tax Changes in 2026
From 6 April 2026, the UK government will introduce significant reforms to inheritance tax rules. Under the new policy, Agricultural Property Relief (APR) and Business Property Relief (BPR) will be subject to a £2.5 million cap for 100% tax relief. Any qualifying value above this limit will only receive 50% relief, which effectively means a 20% inheritance tax charge on the remaining amount.
Married couples and civil partners will be able to transfer unused allowances between them, allowing up to £5 million of assets to qualify for full relief before the reduced 50% relief tier applies.
These inheritance tax changes 2026 UK represent a major shift from previous decades, when farms, estates, and many business assets often benefited from almost unlimited inheritance tax protection. As a result, early planning and proper structuring will become increasingly important for business owners and property holders.
What’s Changing from April 2026?
The updated APR and BPR framework introduces several important changes:
A £2.5 million cap for 100% inheritance tax relief on combined agricultural and business property.
Assets exceeding this threshold will qualify for 50% relief, reducing tax but still creating potential liabilities.
Spouses and civil partners can transfer unused relief allowances, meaning couples may access up to £5 million at full relief.
Trust structures will have their own 100% relief allowance and specific rules regarding exit charges and 10-year anniversary charges.
AIM and EIS shares will move from 100% BPR to 50% BPR, increasing inheritance tax exposure for investors.
The aim of these reforms is to continue supporting smaller farms and family businesses, while ensuring that larger estates contribute more fairly to inheritance tax.
Who Will Be Most Affected?
The inheritance tax changes in 2026 UK are likely to impact several groups, including:
Family farms and agricultural estates
Owners of rural property portfolios
Family-run businesses
Investors holding high-value unquoted shares
Business owners with large illiquid assets
Many of these estates are traditionally described as “asset rich but cash poor.” They have historically relied on uncapped APR and BPR relief to prevent forced asset sales when transferring wealth. The new £2.5 million cap increases the possibility of significant inheritance tax liabilities.
Key Technical Points Business Owners Should Know
1. The £2.5m limit applies to both APR and BPR combined
The cap applies once across all qualifying assets, not separately for agricultural and business property.
2. Spousal transfers can double the allowance
If structured correctly, married couples or civil partners may claim up to £5 million of assets at 100% relief.
3. Trusts receive their own allowances
Each relevant property trust will have a £2.5 million allowance, but with rules covering 10-year reviews, exit charges, and gift interactions.
4. Lifetime gifts after 30 October 2024 are relevant
Gifts of APR or BPR assets made after this date may reduce available allowances if the donor dies on or after 6 April 2026.
5. AIM and EIS investments lose full relief
After April 2026, these shares will qualify for 50% BPR instead of 100%, increasing potential inheritance tax exposure.
6. Instalment options remain available
Inheritance tax liabilities on eligible property can still be paid through 10-year instalments, helping reduce liquidity pressure.
Action Plan for Business Owners Before 2026
1. Assess your APR and BPR exposure
Calculate how much of your estate falls within the 100% relief threshold and how much may fall into the 50% relief category.
2. Review asset ownership between spouses
Ensure assets are structured so both partners can fully benefit from the combined £5 million relief allowance.
3. Update wills and succession plans
Older estate planning documents may no longer work efficiently under the new inheritance tax changes 2026 UK.
4. Reassess gifts and trust arrangements
Gifts made after 30 October 2024 and recently created trusts may affect available relief in the future.
5. Review business valuations and BPR eligibility
This is particularly important for unquoted companies, AIM shares, and EIS investments.
6. Prepare for future tax liquidity
Consider strategies such as life insurance, instalment payments, cashflow planning, or restructuring assets to avoid forced asset sales.

FAQs:
From 6 April 2026, the UK will introduce a £2.5 million cap where qualifying agricultural and business assets receive 100% inheritance tax relief, and any value above that cap receives 50% relief, resulting in an effective 20% tax rate on the excess.
This represents one of the largest overhauls to APR and BPR in decades and affects all business owners and farmers.
If your combined qualifying agricultural or business assets exceed £2.5m, the excess will now be taxed at 20%, which may result in substantial inheritance tax liabilities, especially for family‑owned operations and farms.
This makes tax planning essential for business continuity and family wealth protection.
Yes. The government confirms unused allowance is transferable between spouses or civil partners, enabling couples to claim up to £5 million at 100% relief before the 50% rate applies.
This can dramatically reduce inheritance tax in properly structured estates.
No. From April 2026, AIM and EIS shares will generally qualify for 50% relief only, significantly increasing inheritance tax exposure for investors who relied on full BPR.
Government data shows that 85% of estates that claim APR will not pay more inheritance tax because their asset values fall below the £2.5m threshold. Only larger or high‑value estates face increased tax.
Trusts will receive their own £2.5m allowance, refreshed every 10 years. Any qualifying assets above this limit will be subject to 50% relief during exit charges and anniversary valuations.
This makes trust restructuring vital before April 2026.
Because relief is now capped, many family businesses that were previously fully exempt may face new liabilities, potentially forcing heirs to sell shares or assets to cover tax bills.
Early valuation, restructuring, and will updates are critical
Yes. From April 2026, inheritance tax owed on qualifying agricultural or business property can be paid in 10 annual interest‑free instalments, helping owners avoid cashflow crises or asset sales.
Yes. Aligning assets between spouses ensures both individuals use their full £2.5m allowance, unlocking the combined £5m 100% relief and preventing wasted tax relief.
This is one of the most effective pre‑2026 strategies.
Absolutely. Wills written under old unlimited‑relief rules may no longer be tax‑efficient. Reviewing wills now ensures you correctly use allowances, protect business assets, and reduce future tax liabilities.
Lifetime gifts of APR/BPR assets made after 30 October 2024 may reduce your allowance if death occurs after April 2026. This makes timed gifting a crucial planning area.
You urgently need planning if you are:
- A business owner with assets above £2.5m
- A farmer or rural estate owner
- A family business with share‑based wealth
- An AIM/EIS investor
- A trustee or settlor of asset‑holding trusts
Reliefs change in April 2026, but planning windows are closing fast.
