Business Property Relief, how business owners can reduce inheritance tax on their estate

For business owners, Business Property Relief (BPR) is one of the most significant reliefs available in UK inheritance tax planning. At its most powerful, it can reduce the taxable value of a qualifying business interest to zero, effectively removing it from the estate entirely.

Understanding what qualifies, what has recently changed, and how to structure your affairs to preserve the relief is essential planning for any owner of a trading business.

What is Business Property Relief?

BPR is a relief that reduces the taxable value of qualifying business assets in an estate. The relief applies at either 100% or 50% depending on the type of asset. [1]

100% BPR applies to:

• An interest in a business (including a sole trader business or a partnership interest)
• Unquoted shares in a qualifying trading company (including AIM-listed shares, see below for recent changes)
• Shares that give you control of a quoted company (more than 50% of voting rights)

50% BPR applies to:

• A minority shareholding in a quoted company that does not give control
• Land, buildings, or machinery owned personally but used in a qualifying business or partnership

The two-year ownership rule

To qualify for BPR, you must have owned the business asset for at least two years before your death (or at the time of a chargeable transfer during your lifetime). This means the relief cannot be secured at the last moment, it requires established ownership. [1]

If you acquired shares in a qualifying company less than two years ago, they will not benefit from BPR. Forward planning around this rule is essential for business owners approaching retirement or with health concerns.

What does not qualify for BPR

Not every business interest qualifies. BPR is directed at trading businesses, not investment activities. The following do not qualify:

• Companies whose main activity is holding investments or letting property
• Businesses subject to a binding contract of sale at the time of death
• Not-for-profit or non-trading organisations
• Furnished holiday lets and most property investment companies

A business that is a mixture of trading and investment activity may attract only partial BPR. HMRC examines the nature of the activity, not just the stated purpose of the company.

Changes from April 2026: The £2.5 million cap

The October 2024 Autumn Budget announced significant changes to BPR, effective from 6 April 2026:

For individuals: 100% relief is capped at £2.5 million for qualifying business or agricultural property. Qualifying property above that allowance receives 50% relief, effectively exposing the excess to a 20% IHT charge. [1]

Professional advice is essential to understand how these allowances interact for your specific circumstances.

AIM shares: changes from April 2026

Prior to 6 April 2026, shares listed on AIM (the Alternative Investment Market) and qualifying as unquoted for BPR purposes attracted 100% relief with no cap. This made AIM portfolios a popular estate planning vehicle, assets that could be held in an ISA (providing tax-free growth and income in life) and passed on free of IHT on death.

From 6 April 2026, AIM-listed shares will only attract 50% BPR in all circumstances. The £2.5 million BPR allowance does not apply to AIM shares. This materially changes the planning calculation for investors holding significant AIM portfolios for IHT purposes and may require restructuring. [2]

Agricultural Property Relief

Agricultural Property Relief (APR) operates similarly to BPR but for agricultural land and farm buildings. Relief of 100% or 50% applies depending on whether the agricultural property is owner-occupied or let. APR and BPR can apply simultaneously where a farm business includes both agricultural land and business activities.

The October 2024 Budget announced changes to APR for higher-value agricultural estates, and current guidance applies a £2.5 million allowance across qualifying agricultural and business property. Specialist agricultural property advice is essential for farming families. [3]

Planning to preserve BPR

1. Maintain qualifying status Monitor the business activity mix. A company that drifts toward investment activity (for example, by building up a large cash reserve or acquiring investment properties) may lose BPR on some or all of its assets. Regular reviews ensure the business remains qualifying.

2. Satisfy the two-year rule If you are considering acquiring shares in a BPR-qualifying company as part of estate planning, begin as early as possible to ensure the two-year period is met well before any estate event.

3. Consider lifetime gifts of business assets Business assets given during your lifetime as a PET retain BPR eligibility, if the recipient still holds qualifying assets at the time of the donor's death. Gifting shares early can start the seven-year clock while the asset retains its BPR character.

4. Integrate BPR with wider estate planning BPR-qualifying assets are often the most tax-efficient part of an estate. A well-structured plan might direct BPR-qualifying assets to beneficiaries who would otherwise face a larger IHT bill, while assets with no BPR relief are directed toward exempt transfers (e.g., to a spouse).

Frequently asked questions

Does BPR apply to shares in a holding company? A holding company can qualify for BPR if the group as a whole is predominantly trading. HMRC looks at the economic activity of the group, not just the holding company in isolation. Specialist advice is needed to assess holding company structures.

What happens if I sell my business before I die? Once a business is sold, the proceeds (typically cash) are no longer qualifying assets for BPR. The relief applies to business assets, not the cash received on sale. Estate planning should begin before the sale, not after.

Can BPR and the nil-rate band both apply to the same estate? Yes. BPR reduces the value of qualifying assets before the nil-rate band is applied. The nil-rate band (and RNRB, if applicable) then applies to the remaining taxable estate.

Are there anti-avoidance rules I need to be aware of? HMRC scrutinises BPR claims carefully, particularly for investment businesses, cash-heavy companies, and arrangements that appear to have been structured primarily to secure the relief. The relief is legitimate and widely used, but proper structuring with professional advice is essential.
