Charity Trading Subsidiaries and Gift Aid: When You Need One and How Profits Flow Back Tax-Free

For most smaller charities, commercial activity sits well within the tax-free limits and a trading subsidiary never comes up. But once turnover from non-charitable trading starts to grow, the question changes from "can we do this?" to "how do we structure it so the tax charge does not eat the surplus?" This guide covers both questions, starting with whether you actually need a subsidiary at all.

The short answer: when trading forces a subsidiary

A charity only needs a trading subsidiary when its non-primary-purpose trading exceeds the small trading exemption limits. Within those limits, profits are tax-exempt with no subsidiary required. Beyond them, trading through a subsidiary and donating profits back via corporate Gift Aid keeps the tax charge at nil. Primary-purpose trading (activity that directly furthers charitable purposes) is always tax-exempt without limit, so the subsidiary question applies only to genuinely commercial sidelines.

Primary-purpose vs non-primary-purpose trading

The starting point for any trading analysis is the distinction between primary-purpose and non-primary-purpose activity.

Primary-purpose trading directly carries out the charity's charitable purposes. A museum charging admission to view its collection. A school charging fees for its educational courses. A hospice selling goods and services to patients it supports. This trading is tax-exempt without limit under HMRC's charity tax rules, and no subsidiary is needed to shelter it.

Non-primary-purpose trading is commercial activity that generates income for the charity but does not directly further its purposes. A charity gift shop selling branded merchandise to the general public. A community arts centre running a commercial venue hire operation. A hospice running a café open to the public. This trading is taxable unless it falls within the small trading exemption.

The line is not always obvious. HMRC's charities and trading guidance is the reference point, and in borderline cases trustees may want a specific view before treating activity as primary-purpose.

The small trading exemption: the three tiers and where they break

The small trading exemption gives charities a safe harbour for modest non-primary-purpose trading without requiring a subsidiary. The limit is not a single number; it depends on the charity's gross annual income, producing three tiers:

Charity gross annual income	Maximum non-primary-purpose trading turnover
Under £32,000	£8,000
£32,000 to £320,000	25% of total income
Over £320,000	£80,000

Source: HMRC charities and trading guidance (verified 2026-07-11).

The tier boundaries matter. A charity with £31,000 income has an £8,000 cap. A charity with £33,000 income has a 25% cap, which is £8,250 at that income level. A charity with £400,000 income has an £80,000 cap, not 25% of £400,000 (£100,000). Using the wrong tier, or applying the 25% formula across all income levels, is the most common error in this area.

One further point: the exemption applies to turnover from the trading activity, not profit. If the trading generates £85,000 in sales but only £5,000 in profit, it still fails the £80,000 ceiling test for a charity with income over £320,000.

What happens if you exceed the limit

The consequence of breaching the small trading exemption is harsher than many trustees expect. Tax is due on all profits from that trade, not just the profits on the turnover above the limit. This is confirmed in HMRC's charities and trading guidance: "you'll have to pay tax on all of your profits from that trade."

This all-or-nothing rule makes the exemption a hard boundary. A charity trading at £79,000 of non-primary-purpose turnover (below the £80,000 ceiling, income over £320,000) pays no tax on those profits. A charity trading at £81,000 faces a tax charge on the full profit of the entire trade. There is no gradual taper.

Once a charity anticipates breaching the limit, the practical options are: reduce the trading activity, restructure it as primary-purpose if that is genuinely supportable, or route it through a trading subsidiary before the limit is crossed.

How a trading subsidiary works

A trading subsidiary is typically a private limited company, separate in law from the charity. The charity usually owns all or most of the shares, but the two entities have separate governance, separate accounts, and separate tax positions.

The subsidiary carries out the taxable commercial activity. It invoices customers, employs staff for the trading operation, and keeps its own records. Because it is a company, it is subject to corporation tax on its profits in the ordinary way.

The mechanism that makes the structure tax-efficient is what happens next: the subsidiary donates its profits to the parent charity. When it does so under the corporate Gift Aid rules, there is no corporation tax due on those payments. The subsidiary's taxable profit is reduced by the donation to the extent it has profits to give.

The result: the trading activity happens, the surplus reaches the charity, and the corporation tax liability is eliminated or reduced to a very low figure.

Getting profits back to the charity: corporate Gift Aid explained

Corporate Gift Aid is the mechanism by which the subsidiary's profits flow to the parent charity without triggering a tax charge.

Unlike donor Gift Aid (where an individual donates their own money and the charity reclaims basic-rate tax from HMRC), corporate Gift Aid works differently:

• The subsidiary makes a qualifying charitable donation to the parent charity.
• The donation reduces the subsidiary's taxable profits. If the subsidiary donates all its profits, its corporation tax liability falls to nil.
• The charity receives the cash as a donation; it is not income subject to charity income tax restrictions, and no tax is reclaimed from HMRC on top of the payment.
• The subsidiary pays the donation without deducting tax at source, which is a specific feature of the corporate Gift Aid rules confirmed in HMRC's charities and trading guidance.

To qualify, the donation must be made in the same accounting period in which the profits arise (or within nine months after the period end under current rules). The subsidiary must be profitable; it cannot donate more than its profits. Payments on account before the year-end accounts are finalised are sometimes made, with a true-up once the profit figure is confirmed.

The parent charity must be a qualifying body for the purposes of the charitable donations relief. For HMRC-recognised charities in England, Wales and Scotland this is straightforward.

The deed of covenant question

Older subsidiary arrangements sometimes include a deed of covenant committing the subsidiary to donate profits annually. This was the standard mechanism before the Gift Aid regime was extended to companies in 2000.

Under the current rules, a deed of covenant is not required. A qualifying charitable donation from a company to a charity produces the same tax result under the corporate Gift Aid rules. Many subsidiaries set up before 2000 still have deeds in place; they are not invalid, but they are not the operative mechanism for the tax relief.

If your charity has an existing subsidiary with a deed of covenant, the deed may create legal obligations (requiring the subsidiary to pay regardless of its profit position in a given year) that could be more constraining than a discretionary annual donation. Trustees of both entities should understand what the deed commits them to and whether it remains appropriate.

For new subsidiaries, the standard approach is a board resolution to make a qualifying charitable donation each year, without a formal deed.

Running two entities: accounts, filings and pitfalls

Setting up a trading subsidiary doubles the compliance burden. The obligations to understand from the outset are:

The subsidiary's own compliance

• Corporation tax return filed with HMRC, even if the liability is nil after the charitable donation.
• Annual accounts at Companies House, which must be prepared under the Companies Act (FRS 102 for most small subsidiaries).
• Confirmation statement at Companies House each year.
• Audit, if the subsidiary meets the statutory company audit thresholds, or if the charity group as a whole requires a group audit.

The charity's group reporting

Where the charity controls the subsidiary (which it usually does, as the sole or majority shareholder), the subsidiary's results are consolidated into the charity's group accounts under the Charities SORP (FRS 102). This applies once the charity meets the thresholds that require accruals accounts: a charitable company always, or a non-company charity with income over £250,000 (£500,000 for financial years ending on or after 30 September 2026). The group consolidation adds complexity to the annual accounts preparation and the independent examination or audit process.

Governance pitfalls

Shared trustees or directors between the charity and the subsidiary create connected-party relationships. Any transactions between the two entities (loans, charges, services) must be on arm's-length terms and properly documented. The Charity Commission requires trustees to manage conflicts of interest; where individuals sit on both boards, a formal conflict management protocol is essential.

Charity Commission guidance on charities and trading and on charity investments covers the rules around charities investing in (and lending to) their subsidiaries. The investment and loan rules involve the charity's investment powers under its governing document and the commission's guidance on connected-party transactions. These are not areas to improvise; take formal advice before making a charity-to-subsidiary loan.

Do you actually need one? A decision walk-through

Before committing to the cost and complexity of a subsidiary structure, work through these questions:

1. Is the activity primary-purpose trading? If yes, stop: no subsidiary is needed, and the income is tax-exempt without limit.
2. Does the non-primary-purpose turnover fall within the small trading limits? Use the three-tier table above. If yes, you are in the exemption: no subsidiary needed and no tax due.
3. Are you approaching the limit? If the trading is growing and will breach the cap within one or two years, planning now avoids a rushed restructure later. The subsidiary needs to be in place before the trading transfers to it.
4. Is the trading profitable? If the activity runs at a loss or breakeven, the subsidiary structure has no tax benefit; the governance overhead would not be justified.
5. Is the trading large enough to justify the overhead? Subsidiary formation, annual filings, group accounts preparation, and potentially a group audit add real cost. For low-volume trading generating modest profits, the savings may not cover the compliance cost. This is a calculation worth doing with an adviser before proceeding.

If you reach the end of this walk-through and a subsidiary is the right answer, the practical next steps are company formation, transferring the trading activity to the new entity, setting up the corporate Gift Aid mechanism, and ensuring both sets of accounts are prepared correctly from the first year. Getting the initial structure right is considerably easier than correcting it later.

Scotland note: charity regulation in Scotland is the responsibility of OSCR, with different scrutiny thresholds from England and Wales. The trading tax rules are HMRC rules that apply UK-wide, but the charity governance and accounts framework differs. Scottish charities should confirm their reporting obligations with OSCR guidance alongside this page.
