Business Property Relief and Agricultural Property Relief for IHT: Planning Strategies

The IHT Reliefs That Changed in 2026

Business property relief (BPR) and agricultural property relief (APR) have long been two of the most powerful inheritance tax mitigation tools available under UK law. For business owners, farmers, and investors in qualifying assets, these reliefs could reduce — or in many cases eliminate entirely — the 40% IHT charge on significant asset values.

From 6 April 2026, the rules changed significantly. The unlimited 100% relief that previously applied to many qualifying assets has been capped. The impact on estate plans that relied on these reliefs is substantial, and many HNW individuals and their advisers need to reassess strategies that previously seemed robust.

This guide explains how BPR and APR work, what changed in April 2026, and the planning strategies available in the new environment. All figures are as of the 2025/26 and 2026/27 tax years where relevant.

Business Property Relief: The Basics

What Is BPR?

BPR (s.103–114 IHTA 1984) reduces the value of qualifying business assets for IHT purposes. Before the 2026 reforms, the relief came in two rates:

• 100% BPR: The entire value of the qualifying asset was relieved — no IHT at all
• 50% BPR: Half the value was relieved — IHT charged on the remaining half

Qualifying Assets (Pre- and Post-Reform)

The following types of asset may qualify for BPR, subject to conditions:

Asset Type	Pre-April 2026 Rate	Post-April 2026 Rate
Shares in an unquoted trading company	100%	100% up to £2.5m; 50% above
Interest in an unquoted trading partnership	100%	100% up to £2.5m; 50% above
AIM-listed shares in qualifying trading company	100% (no cap)	50% (no cap)
Quoted minority shareholding in trading co (not controlling)	50%	50%
Land/buildings/plant used in the qualifying business	50%	50%

Note: the £2.5 million threshold and the 50% rate on the excess apply to combined BPR and APR claims across an individual's estate. It is a per-person allowance (originally announced at £1 million in the October 2024 Budget and raised to £2.5 million in December 2025).

Conditions for BPR

To qualify for BPR, the asset must:

1. Be a qualifying type (as above)
2. Have been owned for at least two years by the deceased
3. Not be mainly an investment — a business that consists wholly or mainly of dealing in investments, land, or securities does not qualify. "Mainly" means more than 50% of the activity or asset value. This "mainly investment" test is the most common cause of failed BPR claims.
4. Not be subject to a binding contract for sale at the date of death

The "Mainly Investment" Exclusion

This is the most litigated area of BPR. A business or company that holds rental property, investment portfolios, or other passive investments may fail the mainly investment test unless the non-investment activities are substantial. Relevant factors include:

• The proportion of turnover, profits, and assets attributable to trading versus investment
• The nature and extent of active management activities
• The purpose of the business

Large diversified family businesses with both trading and investment arms are particularly at risk. Professional advice on the BPR position should be obtained before relying on the relief.

Agricultural Property Relief: The Basics

What Is APR?

APR (s.115–124 IHTA 1984) reduces the value of qualifying agricultural property. The rates before and after April 2026:

Property Type	Pre-April 2026 Rate	Post-April 2026 Rate
Owner-occupied agricultural land	100%	100% up to £2.5m combined (with BPR); 50% above
Farmhouses occupied by working farmers	100%	As above
Tenanted agricultural land (with vacant possession within 12 months)	100%	As above
Tenanted agricultural land (other)	50%	50%

Conditions for APR

• The property must be agricultural property in the UK, Channel Islands, or Isle of Man (limited overseas extension for EEA countries may have changed post-Brexit — specific advice is needed)
• It must have been owned for two years (owner-occupied) or seven years (let property)
• The value relieved is limited to the agricultural value — any "hope value" (development potential) is not relieved by APR (though may qualify for BPR if held through a trading business)

The April 2026 Changes: What They Mean in Practice

The £2.5 Million Cap

For deaths on or after 6 April 2026, the combined BPR and APR relief at the 100% rate is capped at £2.5 million per individual (with transitional rules for conditional exemptions granted before April 2026). The cap was originally announced at £1 million in the October 2024 Budget, but the government raised it to £2.5 million in December 2025.

The cap applies per individual, not per estate. Crucially, the £2.5 million allowance is transferable between spouses and civil partners, so a married couple can potentially shelter up to approximately £5 million of qualifying assets at 100%.

Assets above £2.5 million that continue to qualify for BPR or APR receive 50% relief on the excess. The IHT calculation is therefore:

• First £2.5 million of qualifying BPR/APR assets: 100% relief (no IHT)
• Qualifying BPR/APR assets above £2.5 million: 50% relief (IHT at 20% effective rate — being 40% × 50%)
• Non-qualifying assets: 40% IHT (above available nil-rate bands)

Example:

A business owner dies owning an unquoted trading company worth £4 million.

Pre-April 2026: 100% BPR on £4 million — IHT nil.

Post-April 2026: 100% BPR on £2.5 million (nil IHT) + 50% BPR on £1.5 million (IHT on £750,000 at 40% = £300,000). Total IHT liability: £300,000.

A previously zero IHT estate now faces a £300,000 bill. On a £10 million estate, the figure is correspondingly larger.

AIM Shares

AIM-listed shares held for at least two years in qualifying trading companies previously attracted 100% BPR with no cap. From April 2026, AIM shares attract 50% relief across the board (no separate 100% tier for AIM).

This fundamentally changes the economics of AIM-based IHT planning. An investor with £2 million in AIM shares who previously expected zero IHT now faces:

• 50% BPR relief: taxable value £1 million
• IHT at 40% on £1 million (after nil-rate band): approximately £270,000 (depending on other estate assets and available NRB)

For investors who built significant AIM portfolios specifically for IHT planning, this requires urgent review.

Planning Strategies in the New Environment

1. Use Both Spouses' £2.5 Million Allowances

Married couples each have a £2.5 million BPR/APR allowance, and the allowance is transferable between spouses and civil partners. Structuring ownership so that each spouse's allowance is used efficiently can shelter up to approximately £5 million at 100% relief between them.

In practice, this may mean transferring a share of the business or agricultural land to the other spouse, using the unlimited inter-spouse IHT exemption. Care is needed to ensure the transferred share has been owned for two years (BPR) before the transferee dies.

2. Consider Gifting Excess Qualifying Assets

Gifts of qualifying business or agricultural assets during lifetime are PETs (potentially exempt transfers). If the donor survives seven years, the asset falls outside the estate entirely — regardless of whether BPR/APR applies at the date of death.

Gifting assets above the £2.5 million threshold while retaining control of the business (for example, by gifting non-voting shares) may be more attractive than it was previously, given that the IHT cost on the excess is now non-trivial.

3. Life Assurance to Cover the Excess Liability

A whole-of-life or term policy written in trust can be structured to pay out the anticipated IHT liability on the business assets above the £2.5 million threshold. This is a "fund the liability" approach rather than an "eliminate the liability" approach — but it ensures liquidity to meet the tax bill without forcing a sale of the business.

4. Review Business Structure

For businesses that are partly trading and partly investment (property-holding subsidiaries, investment accounts at group level), the structure should be reviewed to ensure BPR still applies and to maximise the qualifying proportion of assets. In some cases, separating investment assets from trading assets within the group structure can preserve BPR on the trading element.

5. Family Trusts for Qualifying Business Assets

Settling BPR-qualifying assets into a discretionary trust before death allows the assets to benefit from BPR on the transfer (subject to the conditions being met), and the trust's ongoing ten-year charge on the assets may be mitigated by BPR if the assets continue to qualify. However, the trust's £2.5 million BPR allowance is separate from the settlor's — adding a further layer of planning opportunity.

6. Agricultural Tenancy Arrangements

For agricultural landowners, the rate of APR on let land (50%) has not changed. However, structuring farming arrangements so that the land is farmed by the owner (or a company they control) rather than let to a tenant may preserve access to the higher-rate relief (now 100% on the first £2.5 million).

Conversely, farmhouse relief requires that the farmhouse is "characteristic of and ancillary to the agricultural land" and that the occupant is a working farmer. HMRC challenge farmhouse relief claims in large estates where the farm is run by employees and the owner occupies the house in retirement.

7. Consider Alternative Structures for Investment Portfolios

For HNW individuals who previously held large AIM portfolios, the changed economics of AIM-based IHT planning may make alternative approaches more attractive:

• Traditional lifetime gifting (PETs)
• EPT structures for non-UK domiciliaries
• Life assurance in trust
• Charitable giving and charitable legacies

The AIM portfolio itself remains a legitimate investment choice — but the IHT rationale for holding it exclusively in AIM is significantly weaker post-2026.

Business Property Relief on Loans

A loan used to finance the acquisition of qualifying business property does not itself qualify for BPR. However, where the loan is secured on the qualifying business property, the debt reduces the value of the estate. HMRC's ordering rules (s.162A IHTA) require that debts secured on relievable assets are deducted from the relievable asset first, before any other part of the estate. This limits the IHT benefit of borrowing against business assets.

Woodland Relief and Heritage Assets

In addition to BPR and APR, IHT law provides:

• Woodland relief (s.125–130 IHTA 1984): The growing timber (not the land) in a commercial woodland can be relieved from IHT, deferring the charge until the timber is sold.
• Heritage assets: Exemptions are available for property of national, scientific, historic, or artistic interest that is conditionally exempt from IHT in exchange for public access conditions.

These are specialist reliefs and require specific advice.
