The Significant Controllers Register

Who counts as a significant controller, how to keep the register, the designated representative, and the penalties for getting it wrong.

By DBMS GlobalLast reviewed: 18 October 2026

The answer first

Almost every company incorporated in Hong Kong must keep a Significant Controllers Register (SCR), a record of the people and entities who ultimately own or control it. The register is kept by the company itself, not filed with the Companies Registry, but it must be available to law enforcement officers on demand.

A significant controller is anyone who, directly or indirectly, holds more than 25% of the shares or voting rights, can appoint or remove a majority of the board, or otherwise exercises significant influence or control. Failure to comply is an offence punishable by a fine of up to HK$25,000 plus HK$700 for each day the default continues.

At a glance

Every Hong Kong-incorporated and re-domiciled company, except listed companies
Filed with the Companies Registry?
No, it is kept by the company

At the registered office or another place in Hong Kong notified to the Registry (Form NR2)
Who can inspect it?
Specified law enforcement agencies, on demand; it is not a public register
Must it be updated?
Yes, within 7 days of the company confirming the relevant particulars
Can it be left blank?
No, if there is no significant controller, the register must say so

Who is a significant controller

A person or entity is a significant controller if any one of these conditions applies:

ConditionIn practice
More than 25% of the issued shares, held directly or indirectlyIncludes shares held through other companies, nominees or arrangements
More than 25% of the voting rights, directly or indirectlyRelevant where share classes carry different votes
The right to appoint or remove a majority of the boardMay come from the articles or a shareholders' agreement
The right to exercise, or actual exercise of, significant influence or controlFor example, a founder who directs the company without holding shares
Control over a trust or firm that itself meets any of the aboveTrustees and those who control the trust or partnership
  • Registrable person: a natural person who is a significant controller. Their particulars must be entered.
  • Registrable legal entity: a company or other legal entity that is a member of the company and is itself a significant controller. It is entered too, and you must keep tracing upward to find the individuals behind it.
Key takeawayHolding exactly 25% is not enough; the test is "more than 25%". But indirect holdings count, so two 20% stakes held through companies you control may combine to make you a significant controller.

How to build and maintain the register

StepWhat happens
1. ReviewCheck the register of members, articles of association, shareholders' agreements and any trust or nominee arrangements.
2. Send noticesGive written notice to anyone you know or have reasonable cause to believe is a significant controller, and to others likely to know their identity.
3. Allow time to respondThe recipient has 1 month to respond. If there is no reply, the company records that fact in the register.
4. Confirm and enterOnce the particulars are confirmed, enter them in the register within 7 days.
5. Appoint a designated representativeRecord their details in the register.
6. Keep it currentUpdate the register whenever ownership or control changes, for example after a share transfer or a new shareholders' agreement.

For individuals the register records name, correspondence address, identity document number, the date they became a significant controller and the nature of their control. For legal entities it records name, company number, registered office, legal form, governing law, the date it became registrable and the nature of its control. Where particulars cannot be confirmed, the register records the steps taken and what is outstanding.

The designated representative

Every company must designate at least one person to provide assistance relating to the register to law enforcement officers. The designated representative must be either:

  • a member, director or employee of the company who is a natural person resident in Hong Kong; or
  • an accounting professional, a legal professional, or a person licensed as a Trust or Company Service Provider.

Most companies with overseas directors appoint their licensed company secretary as designated representative.

Penalties and common mistakes

Penalty exposureA company that fails to keep an SCR, or fails to comply with the related requirements, and every responsible person in default, commits an offence and is liable to a fine of up to HK$25,000 and, for a continuing offence, HK$700 for each day the offence continues. Persons who fail to respond to a notice, or who give false information, may also commit offences.
Common mistakeWhat to do instead
Leaving the register blank because "the shareholders are obvious"Enter every significant controller, or record that there is none
Stopping at a corporate shareholderTrace through to the individuals who ultimately control it
Not updating after a share transferReview the register as part of every change in ownership
No designated representativeAppoint one and record their details
Keeping the register outside Hong KongKeep it at the registered office or a notified place in Hong Kong
How DBMS Global can help
  • Mapping your ownership chain and identifying significant controllers.

In summary

  • Keep an SCR from incorporation; it is not filed but must be produced on demand.
  • "More than 25%", directly or indirectly, or control by other means makes someone a significant controller.
  • Appoint a designated representative and update the register within 7 days of any confirmed change.
