The Companies Act requires all companies to maintain up-to-date registers of people in the following roles:
Members, who are often also known as shareholders
Directors
Secretaries
Auditors
CEOs
Controllers, also commonly known as beneficial owners
These registers (except for the Register of Members for public companies) are maintained by ACRA in electronic form. Whenever there are changes in the appointments or particulars of directors, secretaries, auditors and CEOs, you must update this information via Bizfile within 14 days from the date of the change. If there are changes to the company’s shareholders or share capital, you should file the appropriate share-related transactions via Bizfile.
All registers except for the Register of Registrable Controllers (RORC) are accessible to the public. This is to facilitate trade and interactions among businesses and members of the public, enhance transparency and enable the public to conduct due diligence on the business entities and the people who operate them.
Register of Registrable Controllers
Unless exempted, all companies incorporated in Singapore must set up and maintain a register of registrable controllers (RORC) from the date of incorporation. A controller, or more commonly known as the beneficial owner, refers to an individual or a legal entity that has significant interest in or significant control over a company. This requirement is to provide transparency over the corporate ownership and control structure within the company.
Companies are also required to ensure that the particulars in the RORC are accurate and up-to-date by sending a notice at least annually to every controller. At any time, if there is any update to the controllers’ particulars, companies must update the Register which they keep within 7 days of the controllers confirming the particulars.
You may keep your company’s RORC at your registered office address or at the office of your appointed registered corporate service provider.
Central Register of Registrable Controllers
ACRA also maintains a central Register of Registrable Controllers.
Companies incorporated on or after 16 June 2025 are to set up their private RORC and file information in their RORC with ACRA’s Central RORC on the date of their incorporation. The information must be lodged via Bizfile using the “Update Register of Registrable Controller” eService.
Following incorporation, if there are changes, companies must lodge the change with ACRA within 2 business days after updating the information in their private RORC. The update can be lodged via Bizfile using the “Update Register of Registrable Controller” eService.
