Business Property Relief, now called Business Relief by HMRC, can reduce the value of qualifying business assets for UK Inheritance Tax. From 6 April 2026, 100% relief is generally limited to a £2.5 million allowance shared with Agricultural Relief, while qualifying value above this limit usually receives 50% relief.
What Is Business Property Relief?
Business Property Relief is an Inheritance Tax relief for certain business interests, shares and business assets. It works by reducing the value of qualifying property that is taken into account for IHT purposes.
HMRC now refers to the relief as Business Relief, although the term Business Property Relief, or BPR, remains widely used.
For example, a qualifying interest in a trading business may be eligible for relief. If the relevant conditions are satisfied, all or part of its value can be removed from the amount exposed to Inheritance Tax.
The percentage depends on the type of property and, since 6 April 2026, the available 100% relief allowance.
How Business Property Relief Changed From 6 April 2026
The 2026 reforms introduced an important limit on the amount of qualifying property that can benefit from the 100% rate.
For deaths on or after 6 April 2026, a person generally has a £2.5 million allowance covering the combined value of qualifying business and agricultural property that would otherwise receive 100% relief. Qualifying value above the available allowance receives relief at 50%.
This means Business Relief is no longer necessarily an unlimited 100% exemption for qualifying privately owned business interests.
| Qualifying property | Business Relief treatment from 6 April 2026 |
| Qualifying property within the available £2.5 million 100% relief allowance | Up to 100% relief |
| Qualifying property above the available £2.5 million allowance | 50% relief |
| Certain shares traded on markets such as AIM | 50% relief |
| Certain controlling holdings in listed companies | 50% relief |
| Certain personally owned land, buildings or machinery used by a qualifying business | 50% relief |
The £2.5 million allowance is shared with Agricultural Relief. A person with both qualifying farming assets and business assets does not normally receive a separate £2.5 million allowance for each category.
Can a Spouse or Civil Partner’s Unused Allowance Be Transferred?
Yes. From 6 April 2026, unused 100% relief allowance can be transferred between spouses and civil partners.
If the first person to die does not use all of their £2.5 million allowance, the unused amount may be claimed when the surviving spouse or civil partner dies. This can increase the survivor’s available allowance to as much as £5 million.
There is also an important transitional provision. If the first spouse or civil partner died before 6 April 2026, HMRC treats the full £2.5 million allowance as available for transfer, subject to the relevant claim requirements.
This transferability can materially affect succession planning for family-owned businesses, particularly where a couple’s combined qualifying business and agricultural assets exceed £2.5 million.
What Business Property Qualifies for 100% Relief?
Subject to the £2.5 million allowance and other qualifying conditions, HMRC states that 100% Business Relief can apply to:
- a business or an interest in a business; and
- shares in an unlisted company.
For example, suppose an individual owns a qualifying private trading company valued at £2 million and has no other property using the Business Relief or Agricultural Relief allowance. Assuming all eligibility conditions are met and the full £2.5 million allowance is available, the £2 million qualifying value could receive 100% relief.
The classification of the business remains critical. A company cannot qualify simply because it is privately owned. Its activities must satisfy the Business Relief rules.
What Qualifies for 50% Business Relief?
Some business property receives relief at 50% rather than 100%.
HMRC identifies several categories, including:
- qualifying property above the available £2.5 million 100% relief allowance;
- certain shares traded on markets that do not meet HMRC’s definition of “listed”, including shares traded on the Alternative Investment Market (AIM);
- shares that give the owner control of more than 50% of the voting rights in a listed company;
- certain land, buildings or machinery personally owned by an individual but used in a business in which they were a partner or which they controlled; and
- qualifying land, buildings or machinery held in certain trusts and used by the business.
The rules for AIM and certain other traded shares are particularly important following the April 2026 changes. Qualifying shares in these categories are now restricted to 50% relief rather than benefiting from the new 100% relief allowance.
How the £2.5 Million Business Relief Allowance Works
A simplified example shows why the 2026 change matters.
Assume an individual dies after 6 April 2026 owning £4 million of qualifying business property that would fall within the categories potentially eligible for 100% relief. Assume the individual has the full £2.5 million allowance available and no Agricultural Relief assets competing for it.
The calculation would broadly look like this:
| Qualifying business value | Relief rate | Value remaining after Business Relief |
| First £2,500,000 | 100% | £0 |
| Remaining £1,500,000 | 50% | £750,000 |
| Total | £750,000 |
The example does not mean £750,000 of tax is due. It means £750,000 remains after applying Business Relief and would then form part of the wider Inheritance Tax calculation.
Other exemptions, liabilities and available nil-rate bands may affect the estate’s final taxable value. The actual IHT position therefore cannot be calculated from the business value alone.
The Two-Year Ownership Requirement
Business Relief normally requires the deceased to have owned the qualifying business or asset for at least two years before death.
This requirement can make timing important when someone acquires shares, restructures business ownership or begins succession planning later in life.
Business owners should not assume that purchasing a qualifying business shortly before death immediately creates an entitlement to Business Relief. Detailed rules and exceptions can affect how ownership periods are treated, particularly when business property has been replaced or ownership structures have changed.
Which Businesses Do Not Qualify?
One of the most important limitations is the restriction applying to businesses that mainly conduct certain investment activities.
HMRC states that Business Relief cannot be claimed where a business mainly deals in securities, stocks or shares, land or buildings, or making or holding investments. Not-for-profit organisations are also excluded. Restrictions can additionally apply when a business is being sold or wound up.
This distinction can become particularly important for property-related businesses.
A company that actively carries on a qualifying trade is not necessarily treated in the same way as a company whose activities mainly involve holding investment properties and collecting investment returns. The precise facts and activities of the business matter.
Mixed businesses can require more detailed analysis because the question is not always answered simply by looking at the company’s name or the assets on its balance sheet.
Can Commercial Property Qualify for Business Property Relief?
Commercial property does not automatically qualify simply because a business owns it.
The treatment depends on factors such as who owns the property, how it is used and the nature of the underlying business.
For example, HMRC allows 50% relief in certain circumstances for land or buildings owned personally by an individual and used by a business in which that individual was a partner or by a company they controlled. The underlying business and other eligibility requirements must still satisfy the Business Relief rules.
By contrast, property held mainly as an investment may fail to qualify. A portfolio of buildings held primarily to generate investment returns should therefore not be assumed to qualify in the same way as premises actively used by a qualifying trading business.
What Are Excepted Assets?
Even when the underlying business qualifies, individual assets can sometimes be excluded from Business Relief.
HMRC states that relief cannot be claimed on an asset that was not used mainly for business purposes during the relevant two-year period before the transfer or death, or that was not required for future use in the business.
This can become relevant where a company holds substantial assets that are not genuinely required for its trading operations.
Business owners considering succession planning should therefore look beyond whether the company itself qualifies. The composition and use of assets within the business may also affect the relief ultimately available.
How Business Relief and Agricultural Relief Work Together
Some estates contain both business property and agricultural property. From 6 April 2026, this matters more because the £2.5 million 100% relief allowance is shared between qualifying Business Relief and Agricultural Relief property.
Suppose an estate contains £1.5 million of property qualifying for 100% Agricultural Relief and £2 million of property that would otherwise qualify for 100% Business Relief. The combined qualifying property is £3.5 million.
If the individual has only their standard £2.5 million allowance available, the allowance must be apportioned across the qualifying property. The remaining qualifying value receives relief at 50%. HMRC provides guidance for allocating the allowance where both types of property are involved.
An asset cannot simply receive both Agricultural Relief and Business Relief on the same value. HMRC specifically excludes an asset from Business Relief where it already qualifies for Agricultural Relief, although Business Relief may potentially apply to agricultural property or related business assets that do not qualify for Agricultural Relief.
Does Business Property Relief Mean There Is No Inheritance Tax?
Not necessarily.
Business Relief reduces the value of qualifying business property for Inheritance Tax purposes. The estate’s eventual IHT bill depends on the complete estate, available exemptions and allowances, debts, gifts and other relevant circumstances.
After 6 April 2026, the distinction is especially important for estates containing qualifying business or agricultural property worth more than the available 100% relief allowance.
For instance, property receiving 50% relief still leaves half of its qualifying value in the IHT calculation. That remaining value may or may not ultimately generate tax, depending on the rest of the estate.
Can Business Property Be Given Away During Your Lifetime?
Business Relief can also be relevant to lifetime transfers, but gifting business assets requires careful planning.
Inheritance Tax rules for lifetime gifts interact with ownership periods, the recipient’s subsequent ownership of the property, the donor’s survival period and the status of the business at relevant times. Transitional rules also apply to certain transfers made from 30 October 2024 where the transferor dies on or after 6 April 2026 and within seven years of making the gift.
A lifetime gift can also have consequences outside Inheritance Tax, including potential Capital Gains Tax implications. Business Relief should therefore not be considered in isolation when deciding whether to transfer a company or business assets during the owner’s lifetime.
How Do You Claim Business Property Relief?
Business Relief is not simply established by describing an asset as a family business. The person administering the estate needs to identify the qualifying property and provide the relevant information when dealing with the estate’s Inheritance Tax position.
HMRC provides specific schedules and guidance for Business Relief claims. The evidence required will depend on the type of business interest and the circumstances.
Useful records can include company accounts, share ownership records, partnership agreements, evidence of how long the property was owned, information about business activities and details showing how particular assets were used.
Where both Agricultural Relief and Business Relief apply across an estate, the personal representatives may also need to calculate how the available £2.5 million allowance should be apportioned.
Business Property Relief Planning Checklist
Business owners reviewing their potential position can start with a few practical questions:
- Identify the ownership structure. Determine whether the relevant property consists of a sole trade, partnership interest, private company shares, traded shares or personally owned assets used by a business.
- Confirm the business activity. Establish whether the company or business is primarily trading or mainly conducting activities that Business Relief excludes.
- Check the ownership period. Confirm whether the relevant two-year ownership requirement has been satisfied.
- Review individual business assets. Identify assets that are not used mainly for business purposes or may not be required by the business.
- Calculate combined qualifying property. Include relevant Agricultural Relief property when assessing how much of the £2.5 million 100% relief allowance is available.
- Check transferable allowance. Determine whether unused allowance from a deceased spouse or civil partner can be claimed.
- Review lifetime transfers and trusts separately. These can involve additional rules and transitional provisions.
- Revisit the position after major changes. A sale, restructuring, investment activity, property acquisition or change in how assets are used can alter eligibility.
For valuable businesses or complex estates, professional tax and estate-planning advice can be particularly important because seemingly small changes to ownership or business activity can materially affect the result.
Common Business Property Relief Mistakes
A common mistake is assuming that every privately owned company receives 100% relief. The company still needs to meet the qualifying conditions, and the £2.5 million allowance now limits the value that can receive the 100% rate.
Another is assuming that all property owned by a trading company qualifies automatically. Assets that are not sufficiently connected with the business can be excluded.
Business owners can also overlook the interaction with Agricultural Relief. Since the same £2.5 million allowance covers qualifying agricultural and business property, looking at each category independently can produce an inaccurate estimate.
Finally, relying on pre-April 2026 information can lead to substantially incorrect planning. Older explanations often describe 100% Business Relief without the current £2.5 million allowance or describe AIM shares as potentially qualifying for 100% relief. Those rules have changed.
Conclusion
Business Property Relief remains an important UK Inheritance Tax relief, but the rules changed materially from 6 April 2026. Qualifying business and agricultural property that would otherwise receive 100% relief now shares a £2.5 million 100% relief allowance, with qualifying value above the available allowance generally receiving 50% relief. Unused allowance can potentially transfer between spouses and civil partners.
The headline percentage is only part of the calculation. The nature of the business, ownership period, type of shares, use of individual assets, Agricultural Relief and previous transfers can all affect the amount ultimately available.
Business owners with significant private-company interests should therefore review their succession and estate plans using the post-April 2026 rules rather than relying on older assumptions about unlimited 100% Business Property Relief.

FAQ’s
Yes. Business Property Relief, often abbreviated to BPR, is the commonly used name for the Inheritance Tax relief that HMRC currently describes as Business Relief.
For deaths on or after 6 April 2026, qualifying agricultural and business property that would otherwise receive 100% relief is subject to a combined £2.5 million 100% relief allowance. Qualifying value above the available allowance generally receives 50% relief. Different rules apply to certain assets that qualify only for the 50% rate.
Potentially. An unused £2.5 million allowance can be transferred between spouses or civil partners, potentially giving the survivor an allowance of up to £5 million. Eligibility and claim requirements still need to be satisfied.
Qualifying shares traded on AIM can still receive Business Relief, but from 6 April 2026 they are restricted to 50% relief rather than qualifying for 100% relief.
Not automatically. HMRC excludes businesses that mainly deal in land or buildings or make or hold investments. The actual activities of the business determine whether it meets the Business Relief conditions, so property businesses can require detailed analysis.
The deceased generally must have owned the business or relevant asset for at least two years before death. Special rules can affect some circumstances, so ownership history should be reviewed rather than applying the two-year rule mechanically.
