Business Property Relief and Agricultural Property Relief - a practical guide for advisers
James Dale, Aviva’s Retail Product Manager for Protection, explains one of the most significant changes to Inheritance Tax (IHT) planning in decades. The recent reforms to Business Property Relief (BPR) and Agricultural Property Relief (APR) will have a significant impact on clients who own farms and other businesses. Though both reliefs will continue to exist, the way they operate - and the level of protection they provide - changed fundamentally on 6 April this year.

Why this matters now
The government has reformed how BPR and APR operate for IHT purposes, with changes applying from 6 April 20261, subject to transitional rules for certain lifetime transfers.
The practical impact is that relief which was previously unlimited at 100% is now constrained by1:
- a new combined allowance
- partial (50%) relief above that threshold
- direct interaction with lifetime transfers, trusts, valuation, and liquidity planning
For many high value SME and farming clients, assets that were previously free of IHT may now create real tax liabilities.
But it is important to remember that the detailed application of these reforms depends on the qualifying conditions for relief, the transitional rules, and whether assets are held personally or through trust structures. This is why advisers should therefore treat the new framework as a basis for analysis, not a substitute for case-specific technical review.
What are Business Property Relief and Agricultural Property Relief?
Business Property Relief
Historically, BPR has been a cornerstone of estate and succession planning for business owners.
It reduces the value of qualifying business assets when calculating IHT. It exists to support the continuity of trading businesses, allowing them to be transferred during lifetime or on death without being broken up or sold to meet an IHT charge.
- relief can apply at 100% or 50%2, depending on the nature of the asset and conditions met
- claims are made by executors or trustees as part of the normal IHT administration process
Agricultural Property Relief
APR has long been central to succession planning for farming families, where land and buildings are essential to ongoing operations and difficult to divide or sell without disruption.
It applies to qualifying agricultural property, allowing the agricultural value of that property to be reduced for IHT purposes.
According to GOV.UK guidance3, agricultural property can include:
- land or pasture used to grow crops or rear animals
- farm buildings, farmhouses and cottages (where certain conditions are satisfied)
- certain agricultural shares and securities
Not all farm-related assets qualify. For example, agricultural machinery, livestock and harvested crops do not qualify for it. Property subject to a binding contract for sale is also excluded.
The key changes from April 2026
1. A new £2.5 million allowance for 100% relief1
The most important change is the introduction of a £2.5 million allowance for 100% APR and BPR, applied to the combined value of qualifying agricultural and business property.
In practice, businesses or farms that previously relied on full relief may now face a partial IHT exposure where total qualifying value exceeds the allowance.
2. Transferability between spouses and civil partners1
A significant development is the fact that any unused £2.5 million allowance can now be transferred to a surviving spouse or civil partner.
This introduces additional planning flexibility - but only where ownership, wills and historic relief use are properly reviewed.
3. Trusts are within scope of the allowance1
The reforms don’t just affect individuals. Trusts holding qualifying APR or BPR assets also benefit from the £2.5 million allowance, which applies to:
To prevent abuse, anti-fragmentation rules apply, preventing multiple trusts from being created to multiply access to the allowance. Legislation has also standardised how trust exit charges are calculated, based on unrelieved values, regardless of when the exit occurs.
For trustees and advisers, this significantly increases the importance of robust governance, valuation evidence and record keeping.
4. Chronological use of the allowance across lifetime and death
One of the most technically important - but easily overlooked - changes is how the allowance is applied.
Broadly, the £2.5 million allowance is applied chronologically across relevant lifetime transfers and the estate on death, subject to transitional rules.
Lifetime gifts of qualifying business or agricultural property can therefore reduce the allowance available on death. For individuals, the allowance will broadly refresh after seven years, although the detailed position depends on the timing and nature of earlier transfers. For trusts, the position is different. Separate rules apply under the relevant property regime, including periodic and exit charges, so the operation of the allowance is more complex and cannot be understood simply by reference to a seven-year reset.
This represents a major shift from how many clients historically viewed APR and BPR as “static” reliefs applied only at death.
5. Certain “not listed” shares, including many AIM shares, now qualify for only 50% relief1
A further important change affects shares that are admitted to trading on a recognised stock exchange but are designated as “not listed”, including many AIM shares.
This materially affects portfolios that historically relied on qualifying AIM holdings and similar “not listed” shares as a route to full IHT relief, and means those holdings should now be reviewed as part of any wider estate planning and liquidity strategy.
6. Instalment option extended1
For assets inherited from 6 April 2026 onwards, IHT due on property qualifying for APR or BPR can be paid in up to 10 annual instalments on an interest-free basis, provided these instalments are paid on time. While this can ease pressure, it doesn’t remove the need for liquidity planning, particularly where families want to avoid ongoing debt or uncertainty.
Practical planning issues advisers should focus on
Liquidity: many clients are “asset rich but cash poor”
Wealth is often concentrated in business interests, agricultural land or farms, property, or shares, which:
- may not generate accessible cash
- may be difficult or disruptive to sell quickly
For this reason, liquidity planning therefore moves from a secondary consideration to a core part of effective advice, particularly where families want to avoid forced sales or disruption to trading or farming activity.
Valuations and administrative burden
Accurate valuations are now critical because relief is tied to a defined allowance and may apply only at 50% above the threshold. This increases costs and complexity for individuals and trustees, especially where assets are inherently hard to value - such as privately owned businesses or mixed-use estates.
As a result, valuation accuracy moves from good practice to a core planning requirement. Advisers will need to think proactively about what needs valuing, when valuations should be refreshed, and how evidence will be documented. This is because eligibility, allowance use and IHT exposure now depend directly on those figures.
Trust planning: still relevant, but constrained
Trusts remain within scope of the allowance, but in practice they should be supported by:
- a clear planning purpose
- strong governance and record‑keeping
- robust valuation evidence
Without this, clients risk increased complexity, unexpected charges and HMRC challenge.
Lifetime planning under a single allowance
Gifts and trust transfers should be treated as part of a single, joined‑up allowance strategy rather than isolated actions taken at different points in time.
Failure to track Potentially Exempt Transfers (PETs) and Chargeable Lifetime Transfers (CLTs) can materially affect the position at death.
Succession routes: relief is only one part of continuity planning
Succession planning should support business continuity, leadership transition, tax and legal planning, and funding solutions - not rely on relief alone
Funding IHT without disrupting the plan
The reforms highlight a clear practical gap between tax planning and funding. Even where reliefs apply, partial exposure, timing differences and valuation uncertainty mean families may still face significant liabilities at death.
Within that framework, protection written in trust is commonly used to provide certainty around funding. Because proceeds sit outside the estate and are typically available quickly, they can help meet IHT liabilities without requiring the sale of core business or agricultural assets, while also avoiding delays associated with probate. Used appropriately, this supports both financial outcomes and continuity planning.
Adviser checklist: helping clients respond confidently
1. Establish the facts
- Confirm APR and BPR eligibility and exclusions
- Understand valuation and claim routes
2. Quantify allowance use and exposure
- Calculate how much of the £2.5 million allowance is used by relievable property
- Assess 50% relief exposure above the allowance
- For couples, consider whether unused allowance transferability applies
3. Review trusts and lifetime transfers
- Track PETs and CLTs chronologically
- Plan for standardised trust charge calculations
4. Build a liquidity plan
- Pressure‑test funding options
- Consider instalments and protection written in trust
5. Re-assess AIM and "not listed" share exposure
- Re-check portfolios that previously relied on 100% relief through AIM and ‘not listed’ shares to understand the impact of the new 50% cap
CPD SUMMARY
Key takeaways
- APR and BPR still exist, but the way they work has fundamentally shifted under a combined £2.5 million 100% relief allowance with 50% relief above that level.
- Spouse and civil partner transferability of unused allowance is now a major planning lever from 6 April 2026, with the rules assuming full availability where the first death was before that date.
- Trusts are in scope: they can benefit from an allowance but must navigate anti-fragmentation rules and a standardised approach to some charge calculations.
- The allowance’s chronological application means lifetime gifts and transfers matter more than ever; advisers should track usage across PETs, CLTs and the estate, subject to the transitional rules applying to certain lifetime transfers.
- Valuation accuracy and administrative discipline move from “important” to “essential” because relief outcomes now depend on thresholds and partial relief.
- Many affected clients will be asset rich but cash poor, so the conversation must include a practical plan for liquidity and business continuity.
