Ask most business owners whether their company has any “related corporations” and you will usually get a shrug, or a quick answer about their holding company. In practice, the definition reaches much further than most directors realise, and it quietly determines whether a director can borrow from the company, whether the group qualifies for audit exemption, and whether related-party disclosures are triggered in the financial statements.
The starting point for all of this is Section 5 of the Companies Act 1967, which defines what it means for one corporation to be the holding company, subsidiary or fellow subsidiary of another. Get this wrong, and a company can unknowingly breach the loans-to-directors restrictions, misapply the audit exemption, or miscount its related parties for tax and accounting purposes.
The Section 5 Test: Holding Company, Subsidiary and Fellow Subsidiary
Section 5 of the Companies Act sets out when a corporation is a subsidiary of another. In summary, Company B is a subsidiary of Company A if Company A:
- Controls the composition of Company B’s board of directors; or
- Controls more than half of the voting power of Company B; or
- Holds more than half of Company B’s issued share capital (excluding preference shares that carry no ordinary voting or capital rights); or
- Company B is a subsidiary of a company that is itself a subsidiary of Company A (making B a subsidiary further down the chain)
Company A is then Company B’s holding company. If two subsidiaries share the same holding company, they are “fellow subsidiaries” of one another, even though neither holds shares in the other. A “related corporation” of a company is defined by reference to these relationships: its holding company, its subsidiary, or its fellow subsidiary.
Why Control, Not Just Shareholding, Matters
A common misconception is that the test is purely about the 50% shareholding threshold. In fact, control of the board is an independent limb of the test. A company that holds only 30% of the shares but has the contractual right to appoint a majority of directors can still be a holding company under Section 5. This matters for joint ventures and shareholders’ agreements where board control and economic ownership are deliberately split.
Where the Related Corporation Definition Actually Bites
The Section 5 relationships are not just an academic definition. They are the trigger for several distinct compliance obligations across the Companies Act and financial reporting framework.
| Area | Why the Related Corporation Test Matters |
|---|---|
| Loans to directors (Section 162) | The prohibition on company loans to directors extends to loans made to directors of related corporations, and loans made by related corporations to the company’s own directors |
| Small company audit exemption | A company can only qualify as a “small company” if it is not part of a group, or if the group as a whole also meets the small group thresholds; related corporations must be assessed together |
| Substantial shareholder disclosure | Shareholdings of related corporations are often aggregated when assessing substantial shareholder thresholds |
| Financial assistance (Section 76) | Restrictions on a company financially assisting the purchase of its own shares can extend to arrangements involving related corporations |
| Related party disclosures (FRS 24) | Holding companies, subsidiaries and fellow subsidiaries are related parties for accounting disclosure purposes, requiring disclosure of transactions and balances between them |
Because the same underlying test feeds so many different obligations, getting the group structure chart right, and keeping it current as shares are transferred or new entities are added, is one of the more valuable things a corporate secretary does for a growing group.
Common Situations That Catch Groups Out
1. Assuming a Minority Stake Is Irrelevant
A 40% shareholder with a board-appointment right under a shareholders’ agreement may still be a “holding company” for Section 5 purposes, even without majority equity. Groups sometimes overlook this because they focus only on the percentage of shares held.
2. Missing Fellow Subsidiaries
Directors often know their own parent and subsidiaries but forget that other companies under the same ultimate parent are “related corporations” of their own company too, even though there is no direct shareholding link between the two sister companies. A loan from Company X to a director who also sits on the board of fellow subsidiary Company Y can still fall foul of the loans-to-directors restrictions.
3. Group Audit Exemption Miscalculations
A Singapore company might individually meet the quantitative thresholds for small company audit exemption, yet still require an audit because the group, once all related corporations are correctly identified and aggregated, exceeds the small group thresholds. This is a frequent point of dispute between company secretaries and auditors during annual compliance season.
How to Keep Your Related Corporation Analysis Current
- Maintain a live group structure chart. Update it whenever shares are allotted, transferred, or a new entity is incorporated or acquired.
- Review board appointment rights, not just shareholding percentages. Shareholders’ agreements and constitutions can create control relationships that a shareholding register alone will not reveal.
- Flag related corporations to your auditor and tax agent early. This affects audit exemption eligibility, related party tax adjustments, and transfer pricing documentation.
- Cross-check before approving any loan or guarantee involving a director. Confirm whether the director sits on the board of, or is connected to, any related corporation before the loan is approved.
- Document the analysis. Keep a short memo on file explaining why a corporation is, or is not, treated as related, so the position can be defended on audit or ACRA review.
Frequently Asked Questions
Is a company automatically related to its ultimate holding company, even several layers up?
Yes. Section 5 extends the subsidiary relationship down an entire chain of companies, so a fourth-tier subsidiary is still a subsidiary of the ultimate holding company at the top of the group.
Does an associate or joint venture company count as a related corporation?
Not necessarily. An associate where a company holds, say, 30% of the shares with no board control generally falls outside the Section 5 definition, though it may still be treated as a related party for accounting purposes under FRS 24, which uses a broader test than the Companies Act.
Do trusts and nominee arrangements affect the analysis?
They can. Shares held by a nominee for the benefit of another party may need to be looked at on a “look-through” basis in some contexts, so any nominee shareholding arrangements should be flagged to your corporate secretary before finalising the group chart.
What happens if we get the related corporation analysis wrong on an audit exemption claim?
An incorrect audit exemption claim can mean the company’s financial statements should have been audited and were not, which can affect bank facilities, grant compliance and ACRA filings. If in doubt, seek a formal determination rather than assuming exemption applies.
Getting the Group Structure Right
The related corporation test in Section 5 of the Companies Act sits quietly behind several separate compliance obligations, from the restrictions on loans to directors to the small company and small group audit exemption tests. Because it feeds so many downstream rules, it is worth revisiting your group structure chart whenever shares change hands or a new entity joins the group, and checking it against your statutory registers and register of members.
Groups that are also weighing up a foreign subsidiary structure or reviewing capital reduction should map out related corporations before, not after, the transaction, since the analysis affects shareholder approval thresholds too. For the statutory text, see Section 5 of the Companies Act 1967 on Singapore Statutes Online, and for guidance on financial reporting standards for related parties, see ACRA’s website.
