Identifying Significant Controllers: A Step-by-Step Guide
Reviewed by AIcountant Corporate Services Limited · TCSP Licence No. TC010997
In short: start from the latest share register and work out each direct and indirect holding. Anyone holding more than 25% of the shares or voting rights, or with the right to appoint a majority of the board, or who effectively decides what the company does, is who you have to identify and record.
The first attempt usually goes like this: the company secretary sends a form asking you to fill in the “significant controllers”, you look at the share register — 60%, 30%, 10% between three shareholders — and enter the first two. Only later does it emerge that the 60% holder is an overseas holding company, and it is the natural person behind that who belongs on the register; and that the 10% holder has the right under a shareholders’ agreement to appoint two directors, so they belong there too.
At a glance
| Test | Threshold |
|---|---|
| Issued shares | Holding, directly or indirectly, more than 25% |
| Voting rights | Holding, directly or indirectly, more than 25% |
| Appointing directors | The right to appoint or remove a majority of the board |
| Significant influence | The right to exercise, or actually exercising, significant influence or control over the company |
| Company without share capital | The right to share in more than 25% of the capital or profits |
| Trust / firm | Significant influence or control over the activities of a trust or firm whose trustees / members meet any of the above |
| Who it applies to | Every company incorporated in Hong Kong (other than a company listed on HKEX) |
| Notice of enquiry | The recipient must reply within 1 month |
The most common misunderstanding: these tests are joined by “or”, not “and”. Meeting any one is enough — you do not have to meet them all. Someone holding no shares at all can still qualify through the right to appoint directors.
Step 1: how closely do you have to read the share register?
Three things are needed to start: the latest register of members, every share transfer and allotment record since incorporation, and the shareholders’ agreement if there is one. Copying the old particulars on file at the Companies Registry is not enough — recent transfers may not be reflected there.
Then work out each direct shareholder’s percentage of the issued shares, and circle everyone above 25%.
One point needs care: the test is “more than 25%”. Four shareholders holding 25% each, or a share count that does not divide evenly and produces something like 25.0001%, is not a call to make yourself — hand the register to a professional for confirmation. Get a borderline case wrong and the whole register is wrong from top to bottom.
Step 2: how do you trace indirect holdings up through the layers?
You multiply upward. A common example: your Hong Kong company is 100% held by “A Holdings Limited”, and A Holdings is held 60% by Mr Chan and 40% by Ms Wong. Mr Chan indirectly holds 60% of your company and Ms Wong 40% — both above 25%, so both qualify.
Then distinguish the two kinds of entry. A Holdings is a legal entity, is a direct shareholder of your company, and exercises significant control over it, so it is recorded as a “registrable legal entity”. Mr Chan and Ms Wong, a layer above, are natural persons and are recorded as “registrable persons”. The direct layer is recorded as an entity; the natural persons above it are recorded separately.
Another layer works the same way. Your company ← A Holdings (100%) ← B Investments (40%) + Ms Lee (60%): Ms Lee indirectly holds 60% of your company and is recorded; B is not a direct shareholder of your company and is not itself recorded as a registrable legal entity, but you have to keep tracing upward to see whether any natural person behind B indirectly reaches 25%. Trace through to natural persons — you cannot stop at an overseas company and call it done. On how to build the shareholding structure, see share capital structure.
Step 3: if someone holds less than 25%, are they automatically out?
No. Three categories are routinely missed at this step.
More than 25% of the voting rights. Where the company has issued shares with different voting rights, or a shareholders’ agreement confers extra votes, someone holding only 10% but more than 25% of the votes still qualifies.
The right to appoint or remove a majority of the board. This is an independent test with nothing to do with shareholding. Joint venture arrangements usually specify how many directors each side nominates — reach a majority and it applies.
Actually exercising significant influence or control. The catch-all, for arrangements where someone holds no shares in name but every significant decision needs their nod. It is judged on substance, not on labels — where an arrangement like this exists, do not guess.
How are trusts and partnerships handled?
Trusts and firms are not legal persons, so there is a separate limb: if a person has the right to exercise, or actually exercises, significant influence or control over the activities of a trust or firm, and the trustees of that trust or the members of that firm meet any of the four tests above in relation to your company, then that person is also a significant controller of your company.
In practice this typically means: the trustee of a family trust holds 40% of your company, and the trust deed gives a particular family member the power to direct investment decisions — that family member has to be identified too. These documents are usually not held by the company, so they have to be requested from the trustee. Allow time for it.
What if you cannot trace them, or they will not say?
The law requires the company to take reasonable steps to identify its significant controllers, including giving a notice of enquiry to anyone the company knows or has reasonable cause to believe is a significant controller, or who knows the identity of one. The identification process is itself a statutory duty — this step cannot be skipped.
Whoever receives the notice must reply within 1 month as the notice requires. If no reply comes within the period, the company must note that fact on the register — not being able to trace someone does not mean leaving it blank. You have to leave a record showing “notice given, no reply received”.
Conversely, if the person has already notified the company on their own initiative that they are a significant controller and provided all the required particulars (and the same for legal entities), no notice needs to be given — one step saved.
Once they are identified, what comes next?
Identification is only the start. The particulars of every registrable person and registrable legal entity go into the register; at least one designated representative is appointed with contact details recorded; the register is kept at the registered office or at a Hong Kong address notified to the Companies Registry; and it is updated every time the shareholding or structure changes. For the requirements as a whole, see the significant controllers register; on the designated representative, see what a designated representative is responsible for.

This is general information. The definition of a significant controller, the identification process and the register requirements are as published by the Companies Registry (cr.gov.hk) and set out in the Companies Ordinance (Cap. 622). Judging a particular shareholding or trust structure involves legal analysis; this does not constitute legal advice, and individual situations warrant advice from a professional.
