Version and independent register
ACRA’s 59-page Version 2.0, issued 16 June 2025, explains Part 11A of the Companies Act and the 2017 register regulations. A register of registrable controllers (RORC) is distinct from the members register, nominee director register and nominee shareholder register. A private company must keep an RORC even where ACRA holds its electronic members register; a public company keeps both its members register and RORC. The update introduces incorporation-day records, seven-calendar-day confirmed updates, signed accuracy declarations and mandatory calendar-year verification.
Exemptions and controllers’ continuing duties
Exemptions cover SGX-listed public companies, Singapore financial institutions as defined in the Fourteenth Schedule, companies wholly owned by Singapore’s Government or a statutory body established under a Singapore public Act for a public purpose, wholly owned subsidiaries of those four categories, and overseas-listed companies subject to both regulatory disclosure and adequate beneficial-owner transparency requirements. Comparable substantial-shareholder disclosure can meet the overseas-listing condition. Section 5B governs wholly owned subsidiary status, including specified nominee and subsidiary holdings. Winding up, receivership, judicial management or striking off does not itself create an exemption. Exempt companies must declare their exemption category in the annual return. If an exempt institution controls a non-exempt company, it must still give its controller information to that company.
When the register must start
Companies incorporated on or after 16 June 2025 maintain the register from incorporation. Those incorporated from 31 March 2017 to before 16 June 2025 had 30 days after incorporation; those existing before 31 March 2017 had 60 days after that date. A company later losing an exemption must maintain an RORC within 60 days after becoming subject to the duty, for example following SGX delisting. These historical transition periods are distinct from ongoing update deadlines.
Custody, form and annual-return location
Keep the RORC at the company’s registered office or an appointed registered corporate service provider’s registered office. Declare which location is used in the annual return; there is no separate obligation to lodge or update the location address with ACRA. A resigning provider should hand the register back to the company. Electronic and paper formats are both allowed, with the prescribed form governing even if layout differs from Annex A.
Reasonable steps and notices
Take reasonable steps to identify controllers. Minimally send notices annually to every director and each member directly holding voting shares carrying at least 5% of total voting votes. Send Annex B to suspected controllers and Annex C to people believed to know or likely to know a controller’s identity. Accurate information already supplied can remove the need for that identification notice. Notices may be electronic or paper, need not use registered mail and need not be signed by a director/secretary. Record dispatch and replies. This identification exercise is separate from mandatory annual verification of already registered controllers.
Confirmed and unconfirmed entry deadlines
Enter or update confirmed particulars within seven calendar days. Confirmation can be the controller’s reply, an authorised registered service provider’s reply, or the controller’s own notification in the specified new/change cases. Correction of inaccuracies is confirmed by a reply giving corrected information. Supplied particulars must include the controller’s statement of truth and accuracy, with signature and signature date immediately below. If not confirmed, enter/update available particulars marked unconfirmed within seven calendar days after the end of 30 days from sending the notice. Non-response does not justify leaving a known controller out.
Individual and corporate particulars
Individuals require full name, aliases, residential address, email, contact number, nationality, identity-card/passport number, birth date and actual commencement/cessation dates. Corporate controllers require name, ACRA UEN if any, registered office, email, contact number, legal form, formation jurisdiction and statute, applicable registry name and registration/identification number, and commencement/cessation dates. Dates must be actual events on or after 31 March 2017. Entity type, formation law and registry name are separate fields; ACRA and UK Companies House are registry examples.
No identified controller: executive directors and CEOs
Where the company knows or reasonably believes there is no registrable controller, or cannot identify one after reasonable steps, every director with executive control and every CEO is taken as a registrable controller. Enter their particulars and a note explaining the applicable ground and deemed status within two business days of that knowledge/opinion, and update changes within two business days of knowledge/reasonable belief. The ordinary identification/change notices do not apply to these deemed particulars. When an actual registrable controller is subsequently entered, simultaneously note that the executives are no longer deemed controllers and record that entry date.
Which executives count
A director with executive control manages daily/regular affairs through a senior management position, potentially making significant contracts, appointing key employees, borrowing materially or managing major assets. Director includes the statutory broader definition, such as a person whose directions the board habitually follows and alternate/substitute directors. A CEO is any person, whatever the title, employed by or acting for/under arrangement with the company and principally responsible for managing its whole or part business. Merely listing one nominal officeholder is insufficient if several qualifying people exist.
Mandatory annual verification and event notices
Every calendar year, give every registered controller a notice checking continued controller status, relevant changes and correctness, using Annex F. Known/suspected changes or inaccuracies separately trigger Annex D or E; credible press or enforcement information can justify these notices. Earlier paragraphs say accurate facts or information already supplied can remove an event-driven notice, but this must not erase the distinct annual notice duty in paragraphs 2.0.1(iv) and 6.1.6. Keep evidence of checks and reasons for conclusions. All five notice annexes specify replies within 30 days and signed, dated accuracy declarations.
Significant interest and significant control tests
For share-capital companies, significant interest means an interest in more than 25% of all shares or voting shares carrying more than 25% of voting power. For companies without share capital, it means a direct/indirect right to more than 25% of capital or profits. Significant control exists through the direct/indirect right to appoint/remove directors holding the majority of board votes on all/substantially all matters, more than 25% of member voting rights, or a right to exercise/actual exercise of significant influence or control. Exactly 25% does not satisfy a more-than-25% test.
Counting shares, votes and legal entities
Aggregate share interests across classes, ordinary/preference shares, currencies and differing market values; the interest test is not a value-weighted calculation. For voting power, examine constitution and members records and exclude treasury shares and section 21(4B)/(6C) holding-company shares held by subsidiaries. Corporate controllers must be bodies corporate, with foreign-law status governing foreign entities. Guarantee companies, VCCs, liquidating companies, corporate trustees and qualifying foreign governments can count; a limited partnership and VCC sub-fund cannot. A bankrupt person can still be an individual controller.
When an upstream controller is not registrable
The exception avoiding duplicate registration requires all three conditions: control/interest only through one or more intermediary controllers; the upstream person controls each intermediary; and each intermediary is a company/foreign company required or exempt under the specified schedules, an approved-exchange listed corporation, a required/exempt LLP, an express-trust trustee under Trustees Act Part 7, or a VCC. X wholly owning Z, with Z holding 50% of Y and required to keep an RORC, is recorded in Z rather than Y. Add X’s separate direct 5% in Y and the only-through condition fails, so X is registrable in Y as well.
Indirect rights through majority-stake chains
For indirect capital/profit, board-appointment or member-voting rights, each link must meet the majority-stake rule until the last entity holding the right. Majority stake includes majority voting rights, membership plus majority board appointment/removal, membership plus sole control of majority voting rights, or significant influence/control. The diagram runs A to B to C to D through majority stakes, with D holding a right in X; A indirectly holds that right in X. Apply registrability exceptions separately rather than assuming every upstream person is excluded.
Share interests and the separate 20% attribution rule
Section 7 share-interest rules include formal/informal disposal authority, even if restricted or not attributable to a specific share, known trust interests, and interests attributed through a controlled or instructed entity. A further rule attributes an entity’s share interest where a person, associates or both exercise/control at least 20% of that entity’s voting power. Thus Z with at least 20% votes in X can be deemed interested in X’s more-than-25% shares in Y, subject to registrability rules. Associates include subsidiaries and specified persons/entities following share-related instructions. Purchase contracts can deem interests; bare-trustee interests can be disregarded under the specified provisions. Do not replace this 20% attribution rule with a universal 25% chain test.
Joint interests, stable arrangements and nominees
Each joint holder is treated as holding the whole jointly held interest/right: two people jointly interested in 50% each count as having 50%. A stable arrangement to exercise all/substantially all rights together in a predetermined way attributes combined interests/rights to each participant, whether legally enforceable or based on convention; a one-off arrangement is insufficient. A 10% and 20% voting combination can therefore give each 30%. Shares or rights held as nominee are attributed to the nominator: X holding 30% for Y makes Y, not X on that basis, the controller. Default registration remains subject to the upstream exception.
Influence/control rights and actual behaviour
Control indicates the ability to direct activities; influence indicates ensuring the company generally adopts desired activities. Economic benefit is unnecessary. Rights may arise under constitution, securities or agreements and include absolute decisions/veto over business plans, business changes, borrowing, CEO appointment/removal, incentives and share options. Actual influence requires the cumulative relationships to be examined, such as an outsider consistently directing or influencing the board/CEO or a former founder whose voting recommendations majority shareholders almost always follow. Formal shareholding or directorship is not required.
Excepted roles are not absolute exemptions
Professional advisers including lawyers, accountants, service providers, consultants, investment managers and tax/financial advisers; suppliers/customers/lenders; statutory estate administrators, regulators, liquidators, receivers/managers and judicial managers; employees acting in employment; directors; and one-off voting advisers do not qualify merely by that role. Additional facts can still establish control. A director who owns key intellectual property or important relationships and uses that extra power to influence major decisions cannot rely on the ordinary-director exception.
Privacy, evidence and central filing
The RORC is not public; members and auditors have no entitlement to inspect it. Registrar/ACRA/public agencies may require records and supporting documents, inspect and copy them. Evidence includes NRIC, foreign passport and address proof, foreign registration certificate/address proof and notice replies or independent correspondence. ACRA’s central RORC has existed since 30 July 2020, and all private-register information must be filed. Companies incorporated on or after 16 June 2025 file at incorporation; subsequent filings are due within two business days after private-register entry/update. This central clock differs from seven-calendar-day confirmed entry and two-business-day deemed-executive entry.
Annexes A–F: what each record or notice does
Annex A separates entry date, identity/relationship particulars and remarks showing notice, confirmation, change and unconfirmed status. Annex B asks a suspected controller about own status and other known controllers; C asks knowledgeable persons and reminds actual controllers to notify their own status. D checks continued status, cessation and changes; E seeks corrected particulars; F performs annual status/change/accuracy verification. B–F require responses within 30 days, truth/accuracy statements and dated recipient signatures. Some legacy example rows omit new email/phone fields and one corporate row labels the commencement as individual: apply the full prescribed particulars, not those template omissions.
