If you’re an entrepreneur looking to reinvest profits from your trading business into property, the “obvious” advice often given isn’t good enough — and it could be dangerous. Many business owners set up what’s known as a hybrid group structure, believing it’s smart tax planning. In reality, this structure can quietly strip away valuable Inheritance Tax (IHT) and Capital Gains Tax (CGT) reliefs, leaving entrepreneurs with unexpected six- or seven-figure tax bills.
This article breaks down what a hybrid group structure is, why it looks appealing on the surface, and the specific tax traps that catch entrepreneurs out. You can also find our full breakdown video on YouTube, linked below.
What Is a Hybrid Group Structure?
A hybrid group structure is a company group that combines trading activities with a property investment business under the same holding company.
A typical setup looks like this:
- A holding company sits at the top, owned by the shareholders (for example, split 50/50 between two family members).
- Underneath sits a trading company — a business selling goods or services (for example, a coaching business or an accountancy and tax advisory business).
- Alongside it sits a property investment company, often referred to as an SPV (Special Purpose Vehicle), which earns rental income from a property.
On paper, this looks like efficient planning. Profits made in the trading company can be retained and invested into the property SPV without the owner taking the money out personally and paying personal tax on it. Instead, only corporation tax is paid on the profit — currently variable between roughly 19% and 26.5% — before it’s reinvested into property within the group.
This is the standard advice many entrepreneurs receive, and it seems to work well — until an inheritance tax event or a sale triggers the hidden problems.
Problem 1: Hybrid Groups Put Inheritance Tax Relief at Risk
Historically, trading companies qualified for 100% Business Property Relief (BPR), also called Business Relief, for Inheritance Tax purposes. As of the changes referenced in this update (recorded July 2026), that relief is now:
- Capped at £2.5 million per person at the full rate
- 20% relief (not 40%) on value above that threshold
The critical issue for hybrid groups is whether the group as a whole still qualifies for this relief at all. HMRC applies a number of tests to determine this, and one of the most common tests that catches business owners out is based on balance sheet asset value, not revenue or profit.
Here’s the trap: a £500,000 property might only generate £20,000–£30,000 profit, while a trading business with the same £500,000 revenue could generate £100,000 profit. Even though the trading business is far more profitable, the property sits on the balance sheet as a larger asset value.
If the property investment element of the group exceeds 50% of the group’s overall value (one of several tests HMRC applies), the whole group can lose Business Property Relief on the trading business.
The financial impact can be severe. For example, if a trading business is worth £500,000 and the property assets are worth £1 million, relief could be lost entirely — potentially creating a £200,000 unexpected Inheritance Tax bill simply because of how the group was structured.
Problem 2: Hybrid Groups Also Threaten Capital Gains Tax Reliefs
Trading businesses benefit from several attractive Capital Gains Tax reliefs and exemptions that property investment businesses do not. Unlike the 50% threshold used for the IHT test, the relevant threshold for CGT purposes is property investment value greater than 20% of the group.
If a hybrid group crosses this threshold, entrepreneurs risk losing:
Gift Relief
Gift Relief allows business owners to pass shares to children or a partner without triggering an immediate Capital Gains Tax charge. This relief cannot be claimed within an investment group, but is available for genuine trading companies. Losing it means Capital Gains Tax may become payable simply on gifting shares to family.
Business Asset Disposal Relief (BADR) — Formerly Entrepreneurs’ Relief
Often still referred to as Entrepreneurs’ Relief, Business Asset Disposal Relief offers a reduced 18% Capital Gains Tax rate on the first £1 million of qualifying gains when selling a business. If the group structure fails the trading test because of its property holdings, business owners can lose the ability to claim this relief when selling the group — a costly outcome for anyone planning an exit.
Other Reliefs at Risk
Several additional reliefs can also be affected within a hybrid group structure, including but not limited to:
- Substantial Shareholding Exemption (SSE)
- Investors’ Relief
Why Entrepreneurs Get Caught Out
Many business owners assume that because their trading business is profitable and “overrules” everything else, the group structure is safe. This isn’t the case. As highlighted above, the tests HMRC applies often focus on asset value, not revenue or profitability — meaning a modestly profitable property asset can quietly outweigh a highly profitable trading business when it comes to qualifying for relief.
This mismatch is precisely why hybrid group structures can become a “nasty surprise” — the tax exposure only becomes visible at a taxable event, such as a death (triggering Inheritance Tax) or a sale/gift of shares (triggering Capital Gains Tax) — by which point it’s often too late to restructure efficiently.
How to Avoid Costly Mistakes with Hybrid Group Structures
The overarching advice is simple: where possible, avoid combining trading and property investment activities within the same group.
If you already have a hybrid structure in place, or you’re considering setting one up, the key steps are:
- Seek specialist tax advice before a taxable event occurs — don’t wait for a death, sale, or gift to discover the group doesn’t qualify for relief.
- Review your group structure against the relevant HMRC tests for both Inheritance Tax (the ~50% threshold) and Capital Gains Tax (the ~20% threshold).
- Consider legitimate restructuring options to separate trading and investment activities, preserving eligibility for reliefs such as BPR, Gift Relief, and Business Asset Disposal Relief.
- Don’t assume trading profitability protects you — asset value tests can override profit-based assumptions.
Specialist tax advisors can help entrepreneurs move between structures effectively and legitimately, protecting the reliefs that hybrid groups often put at risk.
Key Takeaways
- A hybrid group structure combines a trading business and a property investment (SPV) business under one holding company.
- It can lose Business Property Relief for Inheritance Tax if the group’s property value exceeds roughly 50% of overall group value.
- It can lose Capital Gains Tax reliefs — including Gift Relief and Business Asset Disposal Relief (18% rate on the first £1 million) — if property investment value exceeds roughly 20% of the group.
- These risks are often invisible until a taxable event (death, sale, or gift) occurs.
- Specialist advice before restructuring or reinvesting profits into property is essential to avoid six-figure tax surprises.
