Business property relief: how it works and who qualifies

Business property relief (BPR) reduces the value of qualifying business assets for inheritance tax purposes. For many estates that include a business, it is the single most important relief available – capable of reducing the IHT bill by tens or hundreds of thousands of pounds, and in some cases eliminating it entirely.

If you are dealing with an estate that includes a business, a share in a partnership, or shares in a private company, BPR is something the executor needs to understand and claim correctly. It will not be applied automatically.

Here is what you need to know at a glance:

• 100% relief is available on qualifying business assets up to a combined value of £2.5 million (from 6 April 2026)
• 50% relief applies to qualifying assets above the £2.5 million threshold, and to certain categories of asset regardless of value
• The deceased must have owned the asset for at least 2 years before death
• The business must be a trading business – companies that mainly hold investments do not qualify
• AIM shares move from 100% to 50% relief from 6 April 2026
• BPR is claimed on the IHT400 form with supplementary schedule IHT413

What is business property relief?

Business property relief is a relief under sections 103–114 of the Inheritance Tax Act 1984 that reduces the taxable value of qualifying business assets when someone dies. It was introduced to prevent inheritance tax from forcing the sale or breakup of family businesses when the owner dies.

The relief works by reducing the value of the business asset before it enters the IHT calculation. If a business qualifies for 100% BPR, its full value is removed from the estate for IHT purposes. If 50% relief applies, half the value is removed – meaning IHT is charged at an effective rate of 20% on that asset (40% on the remaining 50%).

BPR can apply to assets owned directly by the deceased, to assets held in trust, and to assets given away during the deceased’s lifetime (subject to the 7-year gift rules). It sits alongside the nil-rate band and residence nil-rate band – they are separate allowances, not alternatives.

For a broader overview of all IHT reliefs, see our guide to inheritance tax exemptions and reliefs.

What qualifies for BPR?

The relief rate depends on the type of business asset. The table below shows what qualifies and at what rate – reflecting the rules from 6 April 2026 onwards.

Relief rates and qualifying conditions sourced from gov.uk – Business Relief for Inheritance Tax and gov.uk – Agricultural property relief and business property relief changes, verified June 2026.

For assets that attract 100% relief, the £2.5 million figure is a combined allowance shared with agricultural property relief (APR). If the estate includes both business and agricultural assets, the first £2.5 million of their combined value receives 100% relief, with 50% on the excess.

The 2-year ownership requirement

To qualify for BPR, the deceased must have owned the business or asset for at least 2 years before their death. This is a strict requirement – there is no discretion for HMRC to waive it (gov.uk – Business Relief for Inheritance Tax).

The 2-year clock starts when the person acquires the asset. For shares, it is the date of purchase. For a business, it is the date the person started or acquired the business. If someone inherits a business from a spouse, the spouse’s period of ownership can count towards the 2 years – so the surviving spouse does not have to restart the clock.

There is also a replacement property rule. If someone sells one qualifying business asset and replaces it with another, the ownership periods of both can be combined – provided the total period of ownership (with gaps of no more than 3 years) meets the 2-year test. This prevents the relief from being lost simply because a business owner restructured or reinvested.

If the 2-year test is not met, BPR cannot be claimed on that asset. The full value enters the estate and is subject to IHT in the normal way, after any nil-rate band allowance.

The trading test: what counts as a business?

BPR is only available for businesses that are mainly trading businesses. A company whose main activity is holding investments – rental property, shares, cash deposits – does not qualify, regardless of how it is structured or described (gov.uk – Business Relief for Inheritance Tax: what qualifies).

HMRC applies a “mainly” test: is the business mainly a trading business, or mainly an investment business? This is assessed by looking at the overall picture – turnover, profits, assets used, time spent by the owners and employees – rather than any single metric. The HMRC Inheritance Tax Manual at IHTM25261–25280 covers this in detail (HMRC Internal Manual – IHTM25000).

Examples of businesses that typically qualify

• A manufacturing company
• A retail shop or chain
• A professional services firm (accountancy, law, consultancy)
• A construction company
• A hospitality business that operates a hotel or restaurant (as opposed to simply letting rooms)
• A farming operation (which may also qualify for agricultural property relief)

Examples that typically do not qualify

• A property investment company that buys and lets residential or commercial buildings
• A company whose main activity is managing a share portfolio
• A holding company that owns investments rather than trading subsidiaries
• A company that lets furnished holiday accommodation (this is a grey area – some qualify, some do not, depending on the level of services provided)

The distinction between trading and investment can be contentious, particularly for businesses with mixed activities. A company that trades through most of its history but holds a large cash reserve at the date of death may face HMRC scrutiny over whether that cash is an “excepted asset” (see below). Where there is any doubt, specialist advice from a tax adviser or solicitor experienced in IHT business valuations is strongly recommended.

What does not qualify for BPR

Several categories of asset are specifically excluded from BPR, even if they are owned by a trading business (gov.uk – Business Relief for Inheritance Tax: what qualifies):

Investment businesses. If the business’s main activity is dealing in securities, stocks, shares, land, or buildings – or making or holding investments – BPR is not available. This is the most common reason for BPR claims being refused.

Not-for-profit organisations. Businesses run on a not-for-profit basis are excluded.

Businesses being wound up or sold. If the business is in the process of being wound up (unless for the purpose of continuing the business) or being sold at the date of death, BPR does not apply.

Excepted assets. Even within a qualifying trading business, specific assets may be excluded if they were not used mainly for business purposes in the 2 years before death and are not required for future business use. The classic example is a large cash balance held in a company that exceeds what the business needs for its trading operations. HMRC can treat the surplus cash as an excepted asset and deny BPR on that portion of the company’s value.

Assets qualifying for agricultural property relief. Where an asset qualifies for both APR and BPR, agricultural property relief takes precedence. BPR may then apply to any remaining value not covered by APR – for example, farm equipment or the non-agricultural value of a farmhouse. The interaction is explained in detail below.

The April 2026 changes

The Autumn Budget 2024 announced significant reforms to BPR and APR. During the passage of Finance Bill 2025–26, the government amended the proposals – increasing the allowance from the originally announced £1 million to £2.5 million. The increase was confirmed on 23 December 2025, and the changes take effect from 6 April 2026 (gov.uk – Agricultural property relief and business property relief changes).

The £2.5 million combined allowance

From 6 April 2026, the first £2.5 million of combined BPR and APR qualifying assets receives 100% relief. Qualifying assets above that threshold receive 50% relief – giving an effective IHT rate of 20% on the excess.

The allowance is shared between BPR and APR. If an estate includes £2 million of qualifying agricultural property and £1 million of qualifying business property, the first £2.5 million receives 100% relief and the remaining £500,000 receives 50% relief.

Transferability between spouses

The £2.5 million allowance is transferable between spouses and civil partners. If the first spouse to die does not use their full allowance, the unused portion passes to the surviving spouse. A married couple can therefore shelter up to £5 million of qualifying business and agricultural assets at 100% relief. Combined with two nil-rate bands (£650,000 total), a couple could pass on approximately £5.65 million in qualifying assets free of IHT (gov.uk – Agricultural property relief and business property relief changes).

If the first death was before 6 April 2026, the full £2.5 million allowance is assumed to be available for transfer – even though the allowance did not exist at the time of the first death.

AIM shares: reduced to 50% relief

Shares traded on the Alternative Investment Market (AIM) and other markets designated as “not listed” on recognised stock exchanges will receive 50% relief from 6 April 2026, down from 100%. This change applies regardless of the £2.5 million allowance – AIM shares do not count against it or benefit from it. The effective IHT rate on qualifying AIM shares is therefore 20% (40% tax on the remaining 50% of value).

Interest-free instalments

The option to pay IHT in ten equal annual interest-free instalments is extended to all property qualifying for BPR or APR. Previously, interest-free instalments were only available on certain categories of business asset. This is a significant practical benefit, particularly for illiquid business assets where raising cash to pay IHT in a lump sum would be difficult. The mechanics are explained in paying IHT on a business in instalments below.

What the reforms mean in practice

The government estimates that around 1,100 estates will pay more IHT in 2026–27 as a result of these changes. Around 85% of estates claiming APR – including those that also claim BPR – are forecast to pay no additional tax (gov.uk – Agricultural property relief and business property relief changes).

The reforms are legislated in the Finance Act 2026, which amends sections 104 and 116 of the Inheritance Tax Act 1984 and introduces a new Chapter 2A covering the allowance provisions.

APR and BPR: when both reliefs apply

Many estates contain assets that could qualify for either agricultural property relief or business property relief, and some assets touch both. A working farm is the clearest example. The land and farmhouse may qualify for APR, while the wider farming business – livestock, harvested crops, machinery, diversified trading activities such as a farm shop or holiday lets run as a trade – may qualify for BPR.

Which relief applies first

Where an asset qualifies for both reliefs, agricultural property relief is given first on the agricultural value. BPR can then apply to any business value that APR does not cover. The two reliefs do not stack on the same pound of value: you cannot relieve the same agricultural value under both APR and BPR. What BPR does is reach the parts that APR cannot, such as:

• The non-agricultural element of farm buildings or a farmhouse, where it is used in a trading business
• Farm machinery, plant, stock, and livestock held as business assets
• Diversified trading activities carried on alongside the farm

APR only relieves the agricultural value of land and buildings. If a farmhouse is worth more than its agricultural value because of its appeal as a country residence, APR does not cover the excess. Whether BPR can reach any of that excess depends on whether the property is used in a qualifying trading business – often it cannot, which is why the gap between market value and agricultural value can leave a residual IHT charge.

How the combined £2.5 million allowance is allocated

From 6 April 2026, APR and BPR share a single £2.5 million allowance for 100% relief (gov.uk – Agricultural property relief and business property relief changes). The allowance applies to the combined value of all property in the estate that qualifies for 100% APR or 100% BPR. Once the combined qualifying value passes £2.5 million, everything above the threshold drops to 50% relief, regardless of whether it is agricultural or business property.

Where an estate has more qualifying property than the allowance can cover, the executor should consider how the allowance is best allocated, because the 50% relief band gives an effective 20% IHT charge on the excess. HMRC guidance and the IHT400 calculation set out the order in which the allowance is applied. For estates of this size, professional advice on allocating the allowance across APR and BPR assets is worthwhile.

For the agricultural side of these rules, see the agricultural property relief section of our exemptions and reliefs guide.

Valuing the business

A BPR claim stands or falls on the value placed on the business. The executor must report the market value of the business or shares at the date of death – the price they would fetch in a sale between a willing buyer and a willing seller. For a private company with no quoted price, arriving at that figure is one of the hardest parts of administering the estate.

How HMRC values a private company

There is no single formula. The appropriate method depends on the nature of the business, and a valuer will often consider more than one approach before settling on a figure:

• Earnings basis. The most common method for a profitable trading company. The valuer applies a multiple to the company’s maintainable earnings (often EBITDA or adjusted profit). The multiple reflects the sector, the company’s prospects, and the risk attached to its earnings.
• Assets basis. Used for asset-rich businesses, or where the company is worth more broken up than as a going concern. The valuer works from the net value of the company’s assets, adjusted to market value.
• Dividend yield basis. Sometimes used for small minority shareholdings, where the value to the holder is the income stream rather than control. The valuer capitalises the expected dividends.

Minority discounts and control

The size of the shareholding matters. A minority holding (one that does not give control) is usually worth less per share than a controlling stake, because a minority shareholder cannot direct the company. Valuers apply a discount for lack of control and, often, a discount for lack of marketability to reflect the difficulty of selling unquoted shares. The level of discount is a frequent point of negotiation with HMRC.

When HMRC’s Shares and Assets Valuation team gets involved

HMRC has a specialist unit – Shares and Assets Valuation (SAV) – that reviews valuations of unlisted shares and business interests submitted with IHT returns (HMRC Internal Manual – Shares and Assets Valuation Manual). If SAV considers a valuation too low, it will open a negotiation. These discussions can take months, and in some cases years, before a figure is agreed. Interest may run on any additional tax that becomes due as a result.

What IHT413 requires in practice

Schedule IHT413 asks for detailed information about the business: its name and nature, the deceased’s interest in it, the value claimed, the basis of that value, and how the qualifying conditions are met. The executor will usually need to attach the company accounts, an explanation of the valuation method, and evidence supporting the trading status. A thin or unsupported figure invites scrutiny.

Why instructing a specialist early matters

For any business of substance, instructing a specialist business valuer or a tax adviser experienced in IHT valuations early in the administration is a sound investment. A well-evidenced valuation, prepared on a recognised basis with supporting accounts, is far easier to defend than a round-number estimate. It also gives the executor a credible position from which to negotiate if SAV challenges the figure.

BPR and trusts

Business assets are often held in trust, either set up during the owner’s lifetime or created by their will. How BPR applies depends on the type of trust.

Relevant property trusts (including discretionary trusts)

Most lifetime trusts created today – and discretionary trusts in particular – fall within the relevant property regime. These trusts face their own inheritance tax charges, separate from the death of any individual:

• An entry charge when assets are put into the trust (a lifetime chargeable transfer), to the extent the value exceeds the available nil-rate band
• A ten-year periodic charge on each tenth anniversary of the trust, at a maximum rate of 6% of the value of the relevant property
• An exit charge when assets leave the trust between anniversaries

BPR reduces the value brought into these charges. If the trust holds qualifying business property, the relief applies at the entry charge, at each ten-year anniversary, and on exit – provided the property still qualifies as relevant business property at each charge date. If the trust has sold the business and holds cash or investments instead, BPR is not available at the next charge.

From 6 April 2026, a trust’s qualifying business and agricultural property is covered by its own £2.5 million allowance for 100% relief. For existing trusts, this applies from the trust’s next ten-year anniversary on or after 6 April 2026. To prevent owners from splitting assets across several trusts to multiply the allowance, an anti-forestalling rule affects qualifying property transferred into trust on or after 30 October 2024 (gov.uk – Agricultural property relief and business property relief changes).

Interest in possession and IPDI trusts

A trust where a beneficiary has the right to the income (an interest in possession) is treated differently. Where the interest is a qualifying one – for example an immediate post-death interest (IPDI) created by a will – the trust assets are treated as part of the life tenant’s estate for IHT. They are taxed on the life tenant’s death rather than under the relevant property charges.

BPR can apply to qualifying business property held in such a trust when the charge arises on the life tenant’s death, in the same way as if the life tenant had owned the business directly. The usual conditions apply: the property must be relevant business property and the qualifying ownership period must be met.

Trust taxation is one of the more technical areas of inheritance tax. The figures and charge dates depend on the trust’s history and the dates assets entered it. A solicitor or tax adviser experienced in trusts should be involved before relying on BPR within a trust structure.

BPR on death versus lifetime planning

BPR applies both to assets held at death and to gifts of business property made during the owner’s lifetime. The two interact with the 7-year gift rules in a way that catches many people out.

Gifts of business property during lifetime

If someone gives away business property and survives seven years, the gift falls out of the IHT calculation altogether, like any potentially exempt transfer. BPR matters most when the donor dies within seven years, because the gift is then brought back into the estate.

The conditions for BPR to survive the donor’s death

When a gift of business property is reassessed on the donor’s death within seven years, BPR is not automatic. Sections 113A and 113B of the Inheritance Tax Act 1984 impose extra conditions (Inheritance Tax Act 1984, section 113A). For the relief to apply to the gift:

• The recipient must still own the original property at the date of the donor’s death (or at the recipient’s own earlier death)
• If the recipient sold the original property, they must have reinvested the whole of the proceeds into qualifying replacement business property, within three years of the sale
• The property must still be relevant business property at that point – it must still qualify for BPR in its own right, so the business must still be trading and not have become an investment business

This is the successor (or continuing ownership) condition. If the recipient has sold the business and spent the proceeds, or the company has stopped trading or turned into an investment vehicle, BPR is lost on the gift. The gift is then taxed under the normal 7-year rules, with taper relief reducing the tax if death occurred between three and seven years after the gift.

The double interaction with the 7-year rules

The practical effect is that a lifetime gift of business property carries a built-in risk. The donor cannot control what the recipient does with the asset after the gift. A child who inherits the family company and sells it within a few years, then sees the parent die inside the seven-year window, can find that the expected relief has evaporated and the full value of the gift is taxable. Where lifetime gifting of business assets is being considered as part of an estate plan, this risk should be weighed carefully and discussed with a tax adviser.

How to claim BPR

BPR must be claimed by the executor or administrator of the estate. It is not applied automatically. The claim is made as part of the IHT return, using:

• Form IHT400 – the main Inheritance Tax account
• Schedule IHT413 – Business or partnership interests and assets (the supplementary form specific to BPR)

The executor will need to provide details of the business, its activities, the deceased’s interest, the value of the business assets, and evidence that the qualifying conditions are met. HMRC may request further information – particularly around the trading test and whether any excepted assets should be excluded.

The IHT return is due within 12 months of the end of the month in which the person died, although any tax owed is due earlier – by the end of the sixth month after death. For deaths on or after 6 April 2026, a claim to transfer a deceased spouse’s unused £2.5 million allowance must be made within set time limits, so executors should identify a possible transfer early.

For guidance on paying any IHT that is due after BPR has been applied, see our guide to how to pay inheritance tax.

Paying IHT on a business in instalments

Inheritance tax on a business is often hard to pay in a single lump sum, because the value is tied up in the business itself. The instalment option exists for exactly this reason.

When instalments apply

IHT on the following can be paid in ten equal annual instalments (gov.uk – Pay your Inheritance Tax bill: yearly instalments):

• The net value of a business or an interest in a business, after BPR
• Unlisted shares (and controlling listed shareholdings)
• Land and buildings

The first instalment is due at the end of the sixth month after death – the same date the rest of the IHT becomes payable – and then on the same date each following year.

Interest-free from 6 April 2026

For assets that qualify for BPR or APR and pass on a death on or after 6 April 2026, the ten-year instalments are interest-free. This is one of the most useful parts of the April 2026 reforms: an estate with a 50% relief charge on business value above the allowance can spread the remaining tax over a decade without an interest cost, provided each instalment is paid on time. Late payment of an instalment still attracts interest.

How to elect for instalments

The instalment option is elected on form IHT400, by indicating which qualifying assets the executor wants to pay tax on by instalments. There is no separate stand-alone instalment form: the election is part of the main account and supporting schedules. (Form IHT419, despite a similar number, is the schedule for debts owed by the deceased and is not used for instalments.)

What triggers acceleration

The instalment plan is conditional on continuing to hold the asset. If the business, the shares, or the land is sold, all of the outstanding instalments become payable at once – the tax must be paid in full out of the sale proceeds (gov.uk – Pay your Inheritance Tax bill: yearly instalments). Executors planning to use instalments should bear this in mind: a sale of the business part-way through the ten years collapses the remaining schedule into a single payment.

BPR and AIM shares

AIM-listed shares have been one of the most popular inheritance tax planning tools in the UK. Because AIM is not a “listed” exchange for HMRC purposes, qualifying AIM shares have historically attracted 100% BPR – meaning they could be held for 2 years, then pass free of IHT on death.

This made AIM a uniquely attractive option for IHT planning: investors could hold quoted, tradeable shares with growth potential while also benefiting from full IHT relief. Several investment managers built specialist AIM IHT portfolios on this basis.

The April 2026 change

From 6 April 2026, qualifying AIM shares receive 50% relief rather than 100%. The effective IHT rate on AIM shares becomes 20% (compared to 0% previously). This is a significant change for anyone who holds AIM shares as part of an IHT plan.

Key points to understand about the new AIM rules:

• AIM shares are treated separately from the £2.5 million combined allowance. They do not use any of the allowance, and the allowance does not apply to them. AIM shares receive 50% relief regardless of total value.
• The remaining qualifying conditions still apply: the company must be a trading business, the shares must have been held for at least 2 years, and the business must not mainly hold investments.
• The option to pay IHT on AIM shares in ten annual interest-free instalments is available from April 2026.
• AIM shares continue to qualify for BPR – the relief has been reduced, not removed. A 20% effective IHT rate is still substantially lower than the standard 40%.

For investors who already hold AIM portfolios for IHT purposes, the change does not eliminate the benefit – but it halves it. Anyone reviewing their IHT planning in light of these changes should speak to a financial adviser or tax specialist.

Does BPR apply across the whole UK?

Yes. Inheritance tax is a UK-wide tax and is not devolved – it is reserved to the UK government and governed by the Inheritance Tax Act 1984, which applies in England, Wales, Scotland, and Northern Ireland alike. The BPR rates, the 2-year ownership test, the trading test, the £2.5 million allowance, and the instalment rules all apply in exactly the same way wherever in the UK the business is based or the deceased lived.

What differs between the nations is the surrounding estate administration. In Scotland, the process equivalent to probate is called confirmation, and some supporting paperwork uses different terms, but the BPR calculation and the IHT forms (IHT400 and IHT413) are the same. For estates with business assets in Scotland or Northern Ireland, the relief is claimed identically to estates in England and Wales.

Summary

Business property relief is one of the most valuable reliefs in the inheritance tax system. For estates that include qualifying trading businesses, partnership interests, or unlisted shares, it can substantially reduce or eliminate the IHT bill.

From 6 April 2026, the rules have changed. The first £2.5 million of combined BPR and APR assets receives 100% relief, with 50% on the excess. The allowance is transferable between spouses – giving couples up to £5 million of shelter. AIM shares now receive 50% relief rather than 100%, making them less attractive as an IHT planning tool but still beneficial. The same £2.5 million allowance applies to qualifying assets held in trust, and IHT on business assets can be paid over ten interest-free instalments.

The relief must be claimed by the executor on the IHT400 return, with schedule IHT413. For any estate that includes business assets, checking whether BPR applies – and claiming it correctly – should be one of the first steps. Where the business is valuable, the trading status is uncertain, the valuation is complex, or assets are held in trust or were given away within the last seven years, a specialist solicitor or tax adviser can make a significant difference to the outcome.
