What Is Business Asset Disposal Relief and Why Does It Matter?

Business Asset Disposal Relief (BADR) reduces the Capital Gains Tax (CGT) you pay when you sell shares in your trading company. For disposals from 6 April 2025, the rate is 14% on gains up to a £1 million lifetime limit. From 6 April 2026, that rate rises to 18%. Without BADR, you would pay 18% (basic rate) or 24% (higher rate) on the same gains.

The relief used to be called Entrepreneurs' Relief. The name changed in 2020, but the core conditions stayed largely intact. You must hold at least 5% of the ordinary share capital and voting rights, be an employee or officer of the company, and the company must be a trading company (or the holding company of a trading group).

It is that last condition that catches people out when a property investment subsidiary sits inside the group.

The Core Problem: Trading Company vs Investment Company

BADR only applies if the company whose shares you sell is a trading company or the holding company of a trading group. A company whose activities are wholly or mainly investment does not qualify.

Here is the definition HMRC uses. A company is trading if its activities consist of carrying on a trade on a commercial basis with a view to profit. That sounds straightforward. But when a company owns a subsidiary that holds investment property, HMRC looks at the group as a whole. If the subsidiary's activities are investment activities, and those activities are substantial relative to the group, the entire group can fail the trading test.

This is not a grey area. It is a specific anti-avoidance rule designed to stop you sheltering investment assets inside a trading structure and then claiming relief on the shares.

How HMRC Tests the Group

When you hold shares in a holding company that owns a property investment subsidiary, HMRC applies the group trading test. They look at the activities of every company in the group. If the group's activities taken as a whole are wholly or mainly investment, the holding company is not a trading group holding company. Your shares do not qualify for BADR.

The test is not about legal structure. It is about economic reality. If your trading company owns a subsidiary that holds a buy-to-let portfolio, and that portfolio generates significant rental income, HMRC will argue the group is partly investment. If the investment activities exceed 20% of the group's total activities (by turnover, assets, time, or profit), you are at risk of losing the relief.

There is no safe harbour percentage written into the legislation. But in practice, HMRC often challenges claims where investment activities account for more than 20% of the group's activity. The 20% figure comes from case law and HMRC's internal guidance.

Real Example: A Manchester Consultancy With a Property Subsidiary

Take a real scenario. A Manchester-based digital consultancy trades through a holding company. The holding company owns two subsidiaries. One subsidiary carries on the consultancy trade. The other subsidiary owns a freehold office building that the consultancy uses, plus two residential flats let out to tenants.

The consultancy turns over £420,000 a year. The rental income from the flats is £28,000 a year. The property subsidiary's assets (the flats and the office) are worth £1.2 million. The trading subsidiary's assets (work in progress, debtors, cash) are worth £400,000.

On a pure turnover basis, the investment activity is about 6% of the total. But on an asset basis, the investment activity is 75%. HMRC looks at all factors. In this scenario, the group is likely to be treated as wholly or mainly investment because the investment assets dominate. The director who sells their shares would not qualify for BADR on the gain.

The result? They pay 24% CGT instead of 14%. On a £500,000 gain, that is £120,000 in tax instead of £70,000. A £50,000 difference.

Can You Restructure to Qualify?

Sometimes. But the timing is tight. HMRC's anti-avoidance rules mean you cannot restructure purely to claim relief. If you transfer the investment property out of the group within two years of the share sale, HMRC may still look at the position at the date of disposal.

If you are planning a sale, you need to look at the group structure now, not six months before the exit. Options include:

  • Selling the investment property subsidiary to a third party before you sell your shares in the holding company.
  • Distributing the property to shareholders as a dividend in specie (in kind). This triggers a CGT charge on the company and may create a tax liability for you personally.
  • Demerging the investment property into a separate company owned directly by the shareholders, using a tax-advantaged demerger under TCGA 1992 s.192 or a simple capital reduction.

Each option has tax consequences. You cannot simply move the property and ignore the tax. HMRC will treat any step that is part of a scheme or arrangement as ineffective for relief purposes if it is designed to circumvent the rules.

As ICAEW qualified accountants, we see clients come to us six weeks before a sale asking if they can move the property out. Usually it is too late. The planning needs to happen years in advance, or at least before you have a binding agreement to sell.

What About a Company That Trades and Also Holds Investment Property Directly?

If your company trades and also holds investment property directly (not through a subsidiary), the test is different. HMRC looks at the company's activities as a whole. If the investment activities are substantial, the company may fail the trading test.

The same 20% rule of thumb applies. If the rental income, property assets, or management time spent on the property exceeds about 20% of the company's total activity, you risk losing BADR on your shares.

This is common in companies that started as trades but later bought property as an investment. A builder who owns their workshop and also a portfolio of rental houses. A retailer who owns the freehold of their shop and two other commercial units let out. In each case, the investment activity can creep up over time without the director realising the BADR implications.

If you are in this position, we recommend a full review of your company structure with an accountant who understands the BADR rules. The earlier you identify the problem, the more options you have.

The £1 Million Lifetime Limit and How It Interacts With Multiple Disposals

BADR applies to a lifetime limit of £1 million in gains. That limit applies per individual, not per company. If you have already used some of your limit on a previous disposal, you deduct that from the remaining £1 million.

If you hold shares in multiple companies, you can claim BADR on disposals from each, as long as each company meets the trading test. But the total gains covered across all disposals cannot exceed £1 million.

For a company with a property investment subsidiary, if the group fails the trading test, you cannot claim BADR on any of the gain, even if you have unused lifetime limit. The relief is all or nothing on that disposal.

What Counts as a Trading Activity for These Purposes?

HMRC defines trading broadly. It includes manufacturing, retail, professional services, technology, construction, and most commercial activities. Property development counts as trading if the company is in the business of developing and selling property. But holding property for rental income is investment, not trade.

There is a specific exclusion for commercial property used in the trade. If your company owns the freehold of its own office or workshop and uses it for the trade, that is not investment activity. It is a trading asset. The problem arises when the property is held for rental income or capital appreciation, not for use in the trade.

If your company owns a property subsidiary that holds a property let to a third party, that is investment. If the subsidiary holds a property let to the trading company itself, that is still investment in HMRC's view, because the letting activity is not a trade. The property is a trading asset of the group, but the letting activity is not.

This is a subtle distinction. It matters a great deal when HMRC reviews a BADR claim.

Practical Steps Before You Sell

If you are a director of a company that owns a property investment subsidiary, and you are considering selling your shares, here is what to do:

  • Map out the group structure. Identify every subsidiary and what it does.
  • Calculate the proportion of the group's activities that are investment. Use turnover, assets, profit, and management time.
  • If investment activities exceed 20%, assume BADR is at risk.
  • Consider whether you can restructure before the sale. Get professional advice on the tax consequences of any restructuring.
  • If restructuring is not possible, factor the higher CGT rate into your sale price expectations.

Do not rely on a hope that HMRC will not check. BADR claims are reviewed. If you claim relief and HMRC later challenges it, you face interest and penalties on the underpaid tax.

If you are planning an exit and your company has property investments, speak to us before you agree a sale. We can review your structure, identify the risks, and advise on the best path forward.
