Business Property Relief is one of the most valuable — and most underutilised — reliefs available in UK tax law. For business owners it can represent the difference between a family keeping the business they have spent years building and being forced to sell it to pay an Inheritance Tax bill.

Yet despite its significance, many business owners have never had their BPR position properly assessed. They assume their business will qualify, they assume the relief will apply automatically and they assume their standard Will deals with it correctly.

None of these assumptions are safe to make.

What Is UK Business Property Relief?

Business Property Relief (BPR) is a relief from Inheritance Tax that can reduce the value of qualifying business assets by up to 100% for IHT purposes.

In practice this means that qualifying business assets can pass to beneficiaries completely free of Inheritance Tax — regardless of their value. A business worth £2,000,000 with 100% BPR available has a nil IHT value for the purposes of calculating the estate's tax liability.

BPR was introduced to prevent the forced sale of family businesses to meet IHT liabilities on the death of an owner. Without it many successful family businesses would face precisely this fate — forcing the sale of a trading business to generate the cash needed to pay a tax bill.

What Qualifies For Business Property Relief

Not all business assets qualify for BPR. The relief applies at either 100% or 50% depending on the type of asset.

100% Relief

The following assets qualify for 100% BPR:

- A business or interest in a business — including a sole trader business or a partnership interest

- Shares in an unquoted company — including shares in a private limited company

- Shares on AIM — the Alternative Investment Market, which is treated as unquoted for BPR purposes

50% Relief

The following assets qualify for 50% BPR:

- Shares in a quoted company where the transferor had voting control

- Land, buildings or machinery owned by the transferor and used in a business they control

- Land, buildings or machinery held in a trust and used in a business

The Qualifying Conditions

BPR does not apply automatically. The asset must meet several qualifying conditions:

1. The Two Year Ownership Requirement

The business property must have been owned by the transferor for a minimum of two years immediately before the transfer. Business assets acquired within two years of death do not qualify for BPR.

This is a critical planning point. If you are considering acquiring business assets that would qualify for BPR — whether by purchasing a business, taking on a partnership interest or investing in AIM shares — the two year clock starts running from the date of acquisition.

2. It Must Be A Qualifying Business

Not all businesses qualify for BPR. The business must be a trading business — one that is wholly or mainly carrying on a trade or profession.

The following do not qualify:

- Investment companies — businesses whose activities consist wholly or mainly of making or holding investments

- Property investment businesses — companies that hold and let investment properties

- Businesses that deal in securities, stocks or shares as their main activity

This distinction between trading and investment activities is one of the most contested areas of BPR — HMRC scrutinises claims carefully and disputes are common. Mixed businesses — those with both trading and investment activities — are particularly complex.

3. Not A Binding Contract For Sale

At the time of the transfer there must be no binding contract for the sale of the business. If you have agreed to sell your business before you die BPR will not apply.

4. Excepted Assets

Even where a business qualifies for BPR, certain assets held within the business — known as excepted assets — are excluded. Excepted assets are those not used wholly or mainly for the purposes of the business — such as surplus cash or investment assets held within a trading company.

HMRC scrutinises excepted assets carefully and the rules in this area are complex.

Why Your Will Must Be Drafted To Maximise BPR

This is the point that most business owners — and many standard Will writers — miss entirely.

BPR is not applied automatically to business assets in your estate. It must be claimed on the IHT return. And the way your Will is drafted has a significant impact on whether the relief is available and how effectively it is applied.

The Problem With Standard Wills

A standard Will that simply leaves everything to your spouse — or divides your estate equally between your children — may not maximise the BPR available.

Consider a simple example. You have a business worth £600,000 that qualifies for 100% BPR and a house worth £400,000 that does not. Your total estate is £1,000,000.

If your Will leaves everything to your spouse there is no IHT on the first death due to the spousal exemption. But on the second death — when the combined estate passes to your children — the available nil rate bands may be insufficient to shelter the full estate. And by then the BPR qualifying business may have been sold or restructured.

A properly drafted Will — reviewed with knowledge of your BPR position — would structure the estate to ensure the BPR qualifying assets are dealt with in the most tax efficient way.

Specific BPR Provisions

A Director Will may include specific provisions directing that BPR qualifying assets pass to particular beneficiaries in a way that maximises the overall tax efficiency of the estate. This requires a detailed understanding of your specific asset base, your family circumstances and the current BPR rules.

BPR And AIM Shares

AIM shares — shares listed on the Alternative Investment Market — qualify for 100% BPR after two years of ownership. This makes AIM portfolio investment a popular IHT planning strategy for individuals who want to remain invested in the market while reducing their IHT exposure.

However AIM shares carry significant investment risk. The AIM market is less liquid and more volatile than the main market. The tax tail should never wag the investment dog — the investment case must stand on its own merits regardless of the IHT benefit.

Furthermore the government has indicated it may reform BPR on AIM shares in the future — so any planning in this area should be reviewed regularly.

Changes To BPR From April 2026

The Autumn 2024 Budget announced significant changes to BPR that take effect from April 2026. From that date:

- The first £1,000,000 of qualifying business and agricultural property will continue to receive 100% relief

- Qualifying property above £1,000,000 will only receive 50% relief

- AIM shares will only qualify for 50% relief — down from 100%

These changes represent a significant reduction in the benefit of BPR for larger estates and AIM investors. If you have a business worth more than £1,000,000 or a significant AIM portfolio you need to review your planning before April 2026.
