Commercial trading arms: when does a charity's trading subsidiary start to look like a business?
Many charities operate trading subsidiaries to generate income. But as these companies grow, the line between charitable purpose and commercial enterprise becomes harder to draw.
The debate in brief
Most UK charities can trade to some extent. Selling goods and services that directly further the charitable objects — primary purpose trading — is unlimited. But when charities trade for profit in ways not directly related to their objects, things get more complex. The Charity Commission's CC35 guidance distinguishes between primary purpose trading, ancillary trading, and non-primary purpose trading, each with different tax implications.
For non-primary purpose trading above the HMRC small trading exemption threshold, the standard route is a wholly owned trading subsidiary: a separate company that conducts the commercial activity and donates its profits to the parent charity under Gift Aid. Thousands of charities operate trading subsidiaries, from university conference companies to museum retail operations to hospice lottery businesses.
The question is what happens when these subsidiaries grow. A trading arm that begins as a modest income stream can develop into a substantial commercial operation with its own staff, brand identity, and market position. At what point does the subsidiary stop being a mechanism for funding charitable work and start resembling a commercial business that happens to have a charitable parent?
Quick takeaways
| Question | Answer |
|---|---|
| Can charities trade directly? | Yes — primary purpose trading is unlimited and tax-exempt. Non-primary purpose trading is tax-exempt only below the HMRC small trading exemption threshold. |
| What is the small trading exemption? | Charities with income under £32,000 can earn up to £8,000 tax-free. For larger charities, 25% of gross income, capped at £80,000. |
| Why use a trading subsidiary? | To ring-fence commercial risk from charitable assets, and to donate non-primary purpose trading profits to the charity under Gift Aid. |
| How do subsidiary profits reach the charity? | The subsidiary donates profits under Gift Aid, eliminating the corporation tax otherwise due. |
| How many charities have trading subsidiaries? | Thousands — particularly common among universities, hospitals, hospices, museums, and large national charities. |
| What guidance covers this area? | CC35 (Charity Commission), HMRC guidance on charity trading and Gift Aid, and the Charities SORP (FRS 102). |
The arguments
The case for robust trading subsidiaries
Trading subsidiaries allow charities to generate earned income — venue hire, catering, retail, consultancy, licensing — without putting charitable assets at risk. If the venture fails, the charity's core funds are protected. The Gift Aid mechanism is elegant: the subsidiary donates its profits to the parent charity and claims relief that eliminates its corporation tax liability. The NCVO UK Civil Society Almanac 2024 shows that earned income accounts for a larger share of voluntary sector income than voluntary donations. A well-run trading subsidiary provides financial stability that allows a charity to plan for the long term.
The case for concern: when subsidiaries outgrow their parents
The problems begin when the trading subsidiary becomes the dominant entity in practice, even if the charity remains the parent on paper. A university's conference business or a housing association's property development company can grow to the point where it employs more staff and generates more revenue than the charitable activities it exists to fund.
Governance is the most immediate risk. Trustees may lack commercial expertise or be reluctant to challenge a successful management team. CC35 is clear that trustees must maintain control, but oversight can become nominal — particularly when the subsidiary's managing director is also a senior charity figure.
Reputational risk is equally significant. When the public sees a charity operating what appears to be a commercial business — with commercial salaries, branding, and market behaviour — it undermines trust. The perception that charitable status is being used to gain competitive advantage is corrosive, even when the legal position is sound.
There is also mission drift. Subsidiaries develop their own institutional logic and growth ambitions. Over time, a subsidiary may pursue revenue opportunities disconnected from the charity's objects — and the charity may be reluctant to challenge this if the income is needed.
The tax and regulatory boundary
HMRC and the Charity Commission approach this from different angles, but both ask the same question: is the commercial activity genuinely serving charitable purposes?
HMRC's interest is whether Gift Aid on subsidiary profits is being used correctly. The subsidiary must donate its profits to the parent charity — not accumulate them or reinvest in commercial growth. The payment must be made within nine months of the end of the subsidiary's accounting period to qualify for relief.
The Charity Commission's concern is governance. CC35 makes clear that trustees must not allow a subsidiary to operate as an autonomous entity. Where a subsidiary enters into significant contracts, takes on debt, or expands into new markets, trustees need to understand and approve these decisions — not simply receive them as fait accompli in a quarterly board report.
The evidence
The legal framework is established in the Charities Act 2011, HMRC's guidance on trading, and the Charity Commission's CC35. The small trading exemption (Corporation Tax Act 2010, Part 11) allows limited non-primary purpose trading without a subsidiary. Above the threshold, HMRC's Gift Aid guidance sets out the conditions for tax-free profit transfers.
The NCVO UK Civil Society Almanac 2024 reports that earned income accounts for approximately 45% of the voluntary sector's total income. The Charities SORP (FRS 102) requires charities to consolidate subsidiary accounts and disclose related party transactions, making the financial relationship visible in annual accounts.
Charity Commission case work provides occasional illustrations of where the relationship goes wrong — charities failing to oversee subsidiaries, subsidiaries accumulating rather than transferring profits, and trading activities exposing the parent charity to financial risk. The independent schools sector offers a high-profile example: many schools operate trading subsidiaries for lettings and conferencing, and critics in the 2023-24 VAT debate pointed to these as evidence that the schools function primarily as businesses.
Current context
The financial pressures of 2025-26 are pushing more charities toward commercial income. The employer National Insurance Contribution increase, rising costs, and constrained grant funding mean trading income is increasingly important. The Charity Commission's strategic plan for 2025-30 emphasises accountability and governance of connected entities, expecting trustees to demonstrate active oversight of trading subsidiaries. HMRC compliance scrutiny of Gift Aid on subsidiary profits has also increased — a failed claim means the subsidiary pays corporation tax on profits the charity expected to receive gross.
The Charities SORP advisory committee's ongoing review is considering whether reporting requirements for trading subsidiaries need strengthening, particularly around intercompany transactions and governance arrangements.

What this means for charities
Charities with trading subsidiaries — or considering establishing one — should focus on three areas.
First, governance. The subsidiary's board should include people with relevant commercial expertise. The relationship should be governed by a clear agreement covering profit transfer expectations, risk management, brand use, and decision-making authority. Trustees who treat subsidiary oversight as a formality are failing in their duty.
Second, the Gift Aid transfer. Profits should be transferred within the nine-month deadline, and the charity should not become dependent on subsidiary profits that have not yet been transferred — particularly where the subsidiary has variable profitability.
Third, public perception. A charity whose trading subsidiary competes visibly with commercial businesses needs to explain the relationship clearly. The public does not generally understand the trading subsidiary model, and the perception that a charity is "really a business" can be damaging even when the legal structure is proper. Transparent reporting about how trading income funds charitable work is essential.
Common questions
What is primary purpose trading?
Primary purpose trading is selling goods or services that directly further the charity's objects — a museum charging admission, a training charity selling courses, or a theatre selling tickets. It is tax-exempt regardless of scale because the trading activity is itself the charitable work, and does not need a subsidiary.
When does a charity need a trading subsidiary?
When it wants to conduct non-primary purpose trading above the small trading exemption. Above the threshold, trading conducted directly by the charity would be taxable. Routing it through a subsidiary and donating the profits under Gift Aid avoids the charge.
How does Gift Aid work for trading subsidiary profits?
The trading subsidiary donates its taxable profits to the parent charity. This donation is deductible from the subsidiary's taxable profits, eliminating its corporation tax liability. The payment must be made within nine months of the end of the subsidiary's accounting period to qualify. If the deadline is missed, the subsidiary pays corporation tax at the standard rate.
What happens if the trading subsidiary loses money?
If the subsidiary makes a loss, there are no profits to transfer. The loss is contained within the subsidiary's limited company structure — one of the key reasons for using a subsidiary rather than trading directly. However, if the charity has provided a loan or guarantee, it could be exposed. CC35 warns trustees to be cautious about financial support to subsidiaries and to ensure any loans or guarantees do not put charitable funds at disproportionate risk.
Can a trading subsidiary accumulate reserves?
A subsidiary can hold working capital needed for its operations, but should not accumulate significant reserves. A subsidiary that retains profits year after year risks HMRC scrutiny of its Gift Aid claims and Charity Commission questions about governance. Trustees should have a clear policy on working capital needs and ensure surplus profits are transferred promptly.
