Inheritance Tax Reforms: APR, BPR and AIM Relief Changes – What Business Owners, Farmers and Investors Need to Know
The UK’s inheritance tax (IHT) landscape is undergoing one of the most significant periods of change in decades.
Whilst much attention has focused on the proposed inclusion of pension funds within the inheritance tax regime from April 2027, a number of equally important reforms are set to affect farmers, business owners and investors.
The Government has announced plans to restrict valuable inheritance tax reliefs that have historically enabled family businesses and farms to pass between generations with little or no inheritance tax liability. At the same time, investors who have relied on Alternative Investment Market (AIM) shares as an inheritance tax planning tool will see their relief significantly reduced.
Combined with the continued freezing of inheritance tax thresholds until at least 2030/31, these reforms are expected to increase the number of estates facing substantial inheritance tax bills.
For many families, the question is no longer whether inheritance tax planning is necessary, but whether existing plans remain fit for purpose.
A Perfect Storm for Inheritance Tax Planning
The forthcoming reforms should not be viewed in isolation.
Together they represent a significant shift in the Government’s approach to inheritance tax and wealth transfer.
The key changes include:
➡️ Restrictions on Agricultural Property Relief (APR);
➡️ Restrictions on Business Property Relief (BPR);
➡️ Reduced inheritance tax relief for qualifying AIM shares;
➡️ Inclusion of pension funds within the inheritance tax regime from April 2027; and
➡️ Continued freezing of inheritance tax allowances until 2030/31.
Taken collectively, these measures are likely to increase inheritance tax liabilities for many families who previously expected to benefit from extensive reliefs and exemptions.
Agricultural Property Relief (APR) – A Major Change for Farming Families
Agricultural Property Relief has long been one of the cornerstones of inheritance tax planning for farming businesses.
Under existing rules, qualifying agricultural property can benefit from up to 100% relief from inheritance tax, allowing farmland and agricultural businesses to pass between generations without triggering significant tax liabilities.
For many farming families, APR has been essential in preserving family farms and preventing land from having to be sold simply to pay inheritance tax.
What Is Changing?
The Government has announced plans to introduce limits on the amount of qualifying agricultural assets that can benefit from full relief.
Whilst detailed legislation continues to evolve, the broad objective is clear: larger agricultural estates are likely to receive less favourable inheritance tax treatment in the future.
This has created considerable concern throughout the farming community, particularly amongst multi-generational farming businesses where land values have increased substantially over recent decades.
Why This Matters
Agricultural land values have risen significantly across many parts of the UK.
As a result, even relatively modest farming operations may now hold land and assets worth several million pounds.
Without full APR protection, some estates could face inheritance tax liabilities running into hundreds of thousands—or even millions—of pounds.
This raises important questions regarding:
Farm succession planning;
Ownership structures;
Lifetime gifting strategies;
Partnership arrangements; and
Long-term business viability.
Business Property Relief (BPR) – Increased Tax Exposure for Business Owners
Business Property Relief has historically provided similar protection for trading businesses.
For decades, BPR has enabled qualifying business assets to pass free of inheritance tax, helping family-owned businesses survive generational transitions without needing to sell assets or raise funds to meet tax liabilities.
Proposed Restrictions
The Government intends to place limits on the amount of qualifying business property that can benefit from full inheritance tax relief.
Although the precise mechanics continue to be refined, the result is expected to be increased inheritance tax exposure for larger business estates.
Business owners who have assumed their company will continue to qualify for full inheritance tax relief may need to revisit those assumptions.
The Potential Consequences
Business owners often hold the majority of their wealth within their company.
If inheritance tax becomes payable on a greater proportion of business assets, families may face difficult choices, including:
Selling company shares;
Taking on debt;
Disposing of business assets; or
Restructuring ownership arrangements.
Forward planning will become increasingly important to minimise disruption and protect long-term business continuity.
AIM Shares – The End of Full Relief
For many years, qualifying investments listed on the Alternative Investment Market (AIM) have been a popular inheritance tax planning solution.
One of the key attractions of qualifying AIM shares has been their ability to obtain 100% Business Property Relief after just two years of ownership.
This allowed investors to reduce inheritance tax exposure whilst retaining access to their capital.
What Is Changing?
Under the proposed reforms, qualifying AIM investments will continue to benefit from inheritance tax relief, but the level of relief will be reduced from 100% to 50%.
This represents a significant reduction in the attractiveness of AIM portfolios as a standalone inheritance tax planning strategy.
Example
Consider an investor holding a qualifying AIM portfolio worth £500,000.
Under the current rules, the entire investment may qualify for 100% Business Property Relief after two years.
Under the proposed rules, only 50% relief may be available.
Potentially, £250,000 of the portfolio could remain exposed to inheritance tax.
At a 40% inheritance tax rate, this could result in an additional tax liability of up to £100,000.
Whilst AIM investments may still form part of an effective inheritance tax strategy, investors should reassess expectations regarding future tax savings.
Frozen Inheritance Tax Thresholds Continue to Increase Tax Bills
Whilst attention understandably focuses on headline reforms, one of the biggest drivers of future inheritance tax liabilities remains unchanged.
The Government has confirmed that inheritance tax allowances will remain frozen until at least the 2030/31 tax year.
Current thresholds remain:
Nil Rate Band (NRB)
£325,000 per individual.
Residence Nil Rate Band (RNRB)
£175,000 per individual, subject to qualifying conditions.
For married couples and civil partners, this can provide combined allowances of up to £1 million in certain circumstances.
However, these allowances have remained unchanged for many years.
The Hidden Tax Rise: Fiscal Drag
The freezing of allowances creates what economists refer to as “fiscal drag.”
Whilst tax rates remain unchanged, rising asset values gradually pull more individuals into the tax system.
This is particularly relevant given recent increases in:
Residential property values;
Investment portfolios;
Pension wealth;
Agricultural land values; and
Business valuations.
Many individuals who would never previously have considered themselves exposed to inheritance tax are now finding that their estates exceed available allowances.
In effect, the inheritance tax net continues to widen without any formal increase in tax rates.
Planning Opportunities Still Exist
Despite the reforms, inheritance tax planning remains possible.
However, strategies that worked effectively in the past may require adjustment.
Families should consider reviewing:
Succession Plans
Ensure ownership structures and future succession arrangements remain appropriate under the new rules.
Wills and Estate Planning Documents
Many wills were drafted under assumptions that may no longer hold true.
Lifetime Gifting
Making gifts during lifetime can still be an effective method of reducing estate values.
Business Structures
Company ownership and succession arrangements may warrant review.
Farm Ownership Arrangements
Agricultural businesses should assess whether existing structures remain suitable.
Investment Strategies
Investors relying heavily on AIM portfolios for inheritance tax mitigation may need to explore additional planning options.
Pension Planning
With pensions expected to enter the inheritance tax regime from April 2027, pension and estate planning should now be considered together rather than separately.
Common Mistakes to Avoid
As these reforms approach, there are several mistakes individuals should avoid:
Assuming Existing Reliefs Will Remain Unchanged
The inheritance tax environment is changing rapidly. Historic planning assumptions may no longer be valid.
Delaying Action
Many planning strategies require years rather than months to become fully effective.
Focusing on One Reform in Isolation
Pensions, business assets, farms and investments should be reviewed as part of a single integrated estate plan.
Failing to Review Professional Advice
Estate plans created five or ten years ago may no longer deliver the intended outcomes.
The Bottom Line
The combined effect of the pension reforms, restrictions to Agricultural Property Relief and Business Property Relief, reduced AIM relief and continued inheritance tax threshold freezes represents a fundamental shift in inheritance tax planning.
For many years, farmers, business owners and investors have relied upon reliefs that substantially reduced or eliminated inheritance tax liabilities. Those protections are now being narrowed, while more estates are being drawn into the inheritance tax system through frozen allowances and rising asset values.
The message for affected families is clear: do not wait until the new rules arrive.
A comprehensive review of wills, succession plans, business structures, investment arrangements and pension planning could identify valuable opportunities to preserve wealth and reduce future inheritance tax liabilities.
Inheritance tax planning remains available, but the rules of the game are changing. Those who act early are likely to have the greatest range of options available.
