Significant Controllers Register (SCR): what every HK company must keep

If you operate a Hong Kong company — whether a private limited, a branch of a foreign firm, or a non-Hong Kong company registered locally — you almost certainly need to maintain a Significant Controllers Register (SCR). The requirement sits inside the Companies Ordinance (Cap. 622) and applies in addition to the usual books, registers, and filings many directors are already familiar with.

This guide covers the four questions practitioners most often ask:

1. Who counts as a significant controller?
2. What does the register have to contain?
3. Where must it be kept, and who can inspect it?
4. What is the penalty posture for getting it wrong?

It is intended as an operational reference, not a substitute for legal advice.

1. Who counts as a significant controller

A "significant controller" is a person — typically an individual or a legal entity — who meets one or more of the following conditions in relation to your company:

• Holds, directly or indirectly, more than 25% of the issued shares
• Holds, directly or indirectly, more than 25% of the voting rights
• Holds the right to appoint or remove a majority of the board
• Otherwise exercises, or has the right to exercise, significant influence or control over the company

The last limb is deliberately broad. It captures arrangements that fall short of formal share ownership but still give a party meaningful say over the company's decisions — for example, a shareholder agreement, a loan instrument with conversion rights, or a long-term commercial dependency. Whether a particular arrangement crosses the line is fact-specific; the registrar and the courts have applied this limb to a range of structures.

A few practical notes:

• Joint holdings count. If two or more people jointly hold a relevant right, each of them may be a significant controller.
• Indirect interests count. A chain of subsidiaries or holding vehicles through which someone ultimately owns or controls the company is treated the same as a direct holding.
• Trusts and nominees are not exempt. The relevant person is the underlying beneficiary or the person on whose behalf the nominee acts, not the nominee itself.
• Multiple significant controllers are the norm. Most active Hong Kong companies have at least one, and many have several.

If a company has *no* significant controller, the register must still exist — it will record that fact and the date the determination was made.

2. What the register must contain

The SCR must record, for each significant controller:

Identifying information

• For individuals: full name, former or alias names (where known), residential address, identity card or passport number, and date of birth
• For legal entities: name, registration number, registered office, and the legal form of the entity

Nature of control

• A description of how the person meets the "significant controller" test — e.g., ownership of X% of shares, X% of voting rights, right to appoint directors, or other significant influence
• The date on which the person became, and (if applicable) ceased to be, a significant controller

Supporting records

• The company is required to keep a record of the nature of control and the relevant interests, and to record the date of any changes within 7 days after becoming aware of them.

The register itself can be in any legible form — a bound physical book, a spreadsheet, or a dedicated software record — provided it can be produced on demand in Hong Kong.

3. Where the SCR must be kept, and who may inspect

Place of keeping. The SCR must be kept at the company's registered office in Hong Kong, or at a single alternative location in Hong Kong that is recorded on the Companies Register. Moving the SCR to a new location requires notifying the Registrar on Form NR2 within 15 days.

Who may inspect it. Access is tightly controlled:

• The Registrar of Companies can require production of the SCR and supporting records at any time, and the company must comply.
• Authorised officers — including inspectors appointed under the Companies Ordinance — have a parallel right of access.
• Other parties: the SCR is not publicly searchable in the same way as the Companies Register itself. Disclosure to third parties is generally restricted to law enforcement, regulators, and persons authorised under statute.

In practice, the most common real-world trigger is a request from the Registrar during a compliance review. Keeping the SCR at the registered office and having a director or company secretary who knows where it is will resolve most queries quickly.

4. Penalty posture

The Companies Ordinance treats SCR non-compliance seriously. The relevant sanctions include:

• Failure to maintain the SCR — the company and every responsible officer (which can include directors and, in some cases, the company secretary) may be exposed to a fine and, on conviction, a further daily default fine for continued non-compliance (level 4 — a fine up to HK$25,000 plus a daily default fine).
• Failure to keep the SCR at the correct location — similar exposure for the company and its officers.
• Failure to update the SCR within the prescribed window after becoming aware of a change — the company and responsible officers are again within scope if 7 days pass without the update.
• False or misleading entries — knowingly providing false information is an offence carrying up to HK$300,000 and 2 years' imprisonment. This applies both to entries in the register and to information provided to the Registrar on request.
• Obstruction — failing to comply with a Registrar's request, or providing incomplete information, is itself a contravention.

The framing matters. SCR penalties are typically levied on the company as a whole and on the individuals responsible for the default. Directors who delegate the matter entirely and cannot show that reasonable steps were taken to maintain compliance are not insulated from personal exposure.

Operational checklist

Before you close this tab, a short working list:

• Identify every individual and entity that meets any of the four control tests above.
• Record their details in the format required, including the specific limb of the definition they fall under.
• Confirm the SCR is physically or electronically held at the registered office (or at a documented alternative location in Hong Kong).
• Set a reminder to update the register within the statutory window of any change.
• Brief at least one director and the company secretary on what the SCR is and where to find it on demand.

Keeping the record without losing the thread

For a small or mid-sized Hong Kong company, the SCR is rarely the most complex compliance obligation, but it is one of the easiest to neglect — the register gets set up at incorporation, sits in a drawer, and is then forgotten until a Registrar's letter arrives.

If your team is small and the rest of the compliance calendar is already crowded, the practical question is less "what does the SCR require" and more "who is going to keep it current month after month".
