Business Property Relief (BPR) is one of the most powerful tools in UK Inheritance Tax planning. Under the right conditions, it removes IHT entirely from the value of a business or shares in a business — at a rate of either 100% or 50%. For business owners who have also been building a pension alongside their business, the interaction between BPR-qualifying assets and the pension fund is becoming more important: from April 2027, pension assets are expected to be brought within the IHT estate for the first time, changing the relative attractiveness of different wealth-holding structures.
This guide explains BPR's scope and conditions, the pension IHT changes planned for 2027, and the planning frameworks that apply when a business owner wants to minimise IHT across both business and pension assets.
What Is Business Property Relief?
Business Property Relief is a relief from Inheritance Tax under the Inheritance Tax Act 1984. It was designed to prevent the forced sale of a family business simply to fund an IHT bill on the owner's death. BPR has been extended over the years to cover a broad range of assets.
100% BPR relief applies to:
- A business or interest in a business (sole trader or partnership share)
- Unquoted shares in a trading company (including AIM-listed shares in qualifying companies, as they are treated as unquoted for BPR purposes)
- Assets used by a partnership in its business
50% BPR relief applies to:
- Shares in a quoted trading company where the deceased had a controlling interest
- Land, buildings, or plant owned by the deceased personally but used by their company or partnership ("excepted assets" — only the business-use element qualifies)
Two-year holding requirement: the business asset must have been owned for at least two years immediately before death. A business acquired recently before death does not qualify unless it replaced another qualifying business.
Trading test: BPR is available only for trading companies (or groups), not investment companies. A company that primarily holds investments (shares, property, cash) does not qualify. This "trading test" — roughly, more than 50% of the business by activity, assets, and income must be trading — is assessed by HMRC on the facts of each case.
The £2.5 million cap (from 6 April 2026): A significant restriction now applies. From 6 April 2026, 100% BPR (and Agricultural Property Relief) is capped at a combined £2.5 million of qualifying assets per estate (per individual). Qualifying assets above that £2.5 million threshold receive relief at only 50%, not 100% — meaning an effective 20% IHT charge on the excess. The cap was originally announced at £1 million in the October 2024 Budget but was raised to £2.5 million in December 2025; the £2.5 million allowance is transferable between spouses and civil partners (up to roughly £5 million per couple). AIM shares and other "not listed" shares that previously qualified for 100% relief now receive 50% relief regardless of value (they do not benefit from the £2.5 million 100% allowance). This cap fundamentally changes BPR planning for larger business estates: where previously an unlimited business interest could pass entirely free of IHT, only the first £2.5 million now does so at 100%.
What BPR Does Not Cover
BPR does not apply to:
- Buy-to-let property (a common misconception — residential property investment is not a trading activity)
- Cash held in a business in excess of the "excepted assets" threshold (cash above working capital needs is "excepted" and does not attract BPR)
- Shares in companies that primarily invest (investment holding companies, real estate investment vehicles)
- Overseas businesses where the situs rules result in the assets falling outside UK IHT scope under a double taxation agreement (though this is complex and advice-specific)
The excepted assets rule for cash is particularly relevant for profitable businesses that have built up retained earnings. A company with £2 million of net assets of which £1.5 million is cash in the bank may find that only the operating assets (£500,000) qualify for BPR, not the cash balance.
Pension Assets and IHT: The 2027 Change
Under rules in force until April 2027, pension death benefits are generally not part of the deceased's estate for IHT purposes. This has made pensions an efficient vehicle for passing wealth to the next generation — a SIPP or other pension fund, properly nominated, passes to beneficiaries outside the estate. Combined with the pension's income tax advantages during accumulation, this meant that for many HNW individuals, pensions were simultaneously the most tax-efficient savings vehicle and the most IHT-efficient wealth transfer mechanism.
From 6 April 2027, the government has announced (subject to final legislation) that undrawn pension funds will be brought within the deceased's estate for IHT purposes. The mechanics are still being finalised, but the outline position is:
- Remaining pension funds at death will be included in the deceased's estate
- The estate will be subject to IHT at 40% above the nil rate band (£325,000, or up to £500,000 with the residence nil rate band) and spouse/charity exemptions
- Pension scheme administrators will be responsible for reporting and paying any IHT due on pension assets
This represents a fundamental change. For those who had relied on an undrawn pension as the primary IHT-free wealth transfer vehicle, the 2027 change requires a comprehensive review of strategy.
The Planning Interface: Business Assets vs Pension Funds
For business owners, the IHT position now needs to be considered across three pools:
- Business assets (qualifying for BPR at 100% or 50%): these remain IHT-exempt (or 50% exempt) while BPR conditions are met. No change.
- Pension assets: currently IHT-free; from April 2027, within the estate.
- Other assets (property, cash, investments outside pension): within the estate, using nil rate band and reliefs.
The post-2027 planning priority:
If pensions lose their IHT-free status, the relative attractiveness of continuing to accumulate wealth in the pension (rather than drawing it and deploying elsewhere) changes. In particular:
Drawing pension assets and investing in BPR-qualifying assets — if the pension fund is drawn down (taxable as income, but the fund then depletes from the estate) and the cash is invested in BPR-qualifying assets, the assets may qualify for BPR after two years' holding. Note the post-6 April 2026 limits: trading business interests and unquoted shares qualify for 100% relief only up to the £2.5 million combined cap per estate (50% above it), and AIM ("not listed") shares now qualify at 50% relief only, regardless of value.
Using the pension lifetime and spousal exemption: where married, pension funds passing to a surviving spouse may continue to pass IHT-free (spousal exemption applies). The IHT problem primarily arises on the second death — the funds must then pass to children or other non-spouse beneficiaries and will be subject to IHT.
Charitable gifts from pension: pension assets directed to a charity (via nomination or will) may pass entirely IHT-free under the charitable exemption. This can be relevant for philanthropically inclined clients.
BPR and Pension Interaction: Specific Scenarios
Scenario 1: Business Owner Selling the Business Before Retirement
A business owner sells a qualifying trading company for £3 million. At the point of sale, the BPR ceases — the proceeds are cash, not a business. Unless reinvested in another qualifying business within three years (replacement property provisions), IHT applies to the cash.
Planning considerations:
- Reinvesting a portion of the sale proceeds in AIM portfolios (BPR-qualifying after 2 years) — various AIM BPR services are available from investment managers
- Contributing proceeds to pension (subject to AA limits, but a significant cash event can be combined with carry forward and employer contributions where a company remains active)
- Structuring the pension as the primary accumulated pot and using post-sale invested assets in BPR vehicles for the estate
Scenario 2: Business Owner Retaining the Business to Death
Where a business owner holds BPR-qualifying shares to death, the estate receives 100% BPR on those shares up to the £2.5 million combined cap per estate (from 6 April 2026), with 50% relief on the value above £2.5 million. The pension is currently IHT-free, and from 2027 will be within the estate.
Post-2027 planning: the pension should be drawn during lifetime to fund living expenses (reducing the pension estate), while the business assets (BPR-qualifying) remain untouched and pass IHT-free. This effectively reverses the "preserve the pension, spend everything else" strategy that many advisers recommended pre-2027.
Scenario 3: Company Pension with Excessive Cash (Excepted Assets)
A director's company holds a large SSAS or group personal pension. The company itself has substantial retained profits held as cash. The company shares might not qualify fully for BPR due to the excepted assets test on cash.
Planning: consider paying the excess cash out as employer pension contributions to the SSAS (reducing the non-qualifying cash balance; contributions to a pension are allowable business expenses within the AA) — this simultaneously reduces the excepted assets problem and grows the pension fund.
AIM Shares as a BPR-Pension Complement
AIM (Alternative Investment Market) shares in qualifying trading companies attract BPR after a two-year holding period. Until 5 April 2026 this was 100% relief; from 6 April 2026, AIM and other "not listed" shares qualify for 50% relief only (an effective 20% IHT charge), and they do not benefit from the £2.5 million 100% allowance available to unquoted trading businesses. Several investment managers offer managed AIM BPR portfolios designed for IHT planning, but the relief is now materially less generous than before April 2026.
AIM shares can be held within an ISA (income and gains tax-free, though the ISA is within the IHT estate) or within a general investment account. They cannot be held within a pension (connected party rules and the prohibited investment regime for pension funds restrict pension investment in AIM shares where the member or employer is connected to the company — unconnected AIM shares can technically be held in SIPPs but are unusual given the complexity).
Post-2027, the combination of:
- Drawing pension funds (taxably) during retirement
- Reinvesting in a managed AIM BPR portfolio
- Holding for two years to crystallise BPR
...creates a planning pathway from a post-2027 taxable pension estate to a partially BPR-qualifying estate. The income tax cost of drawing the pension is a real cost, and the IHT saving is now more limited than it once was: from 6 April 2026 AIM shares attract only 50% BPR (an effective 20% IHT charge rather than full exemption). The saving may still outweigh the income tax cost depending on the tax position at drawdown, but the post-2026 cap makes the maths considerably less favourable than under the old 100% AIM relief.
Family Investment Companies and Pension Co-ordination
A Family Investment Company (FIC) is a private limited company used to hold and invest family wealth, with shares structured to allow income and capital to pass to the next generation tax-efficiently. FICs are not in themselves BPR-qualifying (they are investment holding companies, not trading), but they are sometimes used alongside pensions.
The interaction: pension income drawn in retirement can be contributed to an FIC (as a subscription for shares, or as a gift of ISA proceeds), though the contribution must be made from post-tax pension income. FIC assets can then grow within the FIC, with dividends or capital distributions flowing to family members.
FIC strategies require bespoke corporate and tax advice and are not appropriate for all clients. They are most effective for those with very large estates (£5 million+) and long planning horizons.
Compliance Caveats
BPR rules — including the trading test, the two-year holding period, and the excepted assets provisions — are determined on the facts of each case and can change with legislation. The 2027 pension IHT changes are proposed as of June 2026 and will only take effect when the relevant Finance Act provisions are enacted and in force; the final legislation may differ from current proposals.
