ACRA is the registrar, not a separate body
Singapore does not have a standalone Registrar of Companies office in the way some jurisdictions do. The function is carried out by the Accounting and Corporate Regulatory Authority (ACRA), a statutory board under the Ministry of Finance. ACRA administers the Companies Act and serves as the single authority for the registration, regulation, and dissolution of business entities in Singapore. When people refer to the "ROC" or "Registrar of Companies Singapore", they mean ACRA acting in that statutory capacity. The Registrar is a designated role within ACRA, empowered by the Companies Act to make binding decisions on matters such as name approvals, incorporation, and striking off.
The core functions the registrar performs
The Registrar's responsibilities span the entire lifecycle of a Singapore business entity. At formation, the Registrar approves or rejects proposed company names, incorporates companies once the required documents are submitted, and issues the certificate of incorporation. Ongoing, the Registrar maintains the public register of business entities, which anyone can search through BizFile+. This register records directors, shareholders, registered addresses, and share capital. The Registrar also enforces statutory compliance: companies must file annual returns and, where required, financial statements within prescribed deadlines. Where a company fails to comply or has ceased operations, the Registrar has the power to strike it off the register, effectively dissolving it.
BizFile+ is the primary interface for all filings
Almost all interactions with the Registrar happen through BizFile+, ACRA's online portal. Through BizFile+, you can incorporate a new company, update business particulars such as a change of directors or registered address, file statutory documents including annual returns, and retrieve publicly available corporate information on any registered entity. The portal is available around the clock and uses Singpass for authentication. Foreign founders who do not hold a Singpass account will need a locally resident authorised representative, such as a corporate secretary or nominee director, to file on their behalf. This is one of the practical reasons most overseas founders engage a corporate services firm from the outset.
Annual returns and financial statements are recurring obligations
Every Singapore-incorporated company must file an annual return with the Registrar each year. The annual return confirms or updates the company's key particulars and is distinct from the company's tax filing with IRAS. Depending on the company's size and whether it qualifies as a small company, financial statements may need to be filed alongside the annual return, either in full XBRL format or in simplified XBRL format. Missing the filing deadline triggers late penalties, and persistent non-compliance can lead to the Registrar initiating a striking-off. Keeping these deadlines is a core part of what a corporate secretary manages on behalf of the company.
What the public register means for your business
Because the register is public, any third party can look up your company's directors, shareholders, registered address, and share capital at any time. This transparency is by design: it underpins trust in Singapore's business environment. It also means that the details you file with the Registrar carry real-world consequences. A wrong registered address can cause you to miss statutory notices. An outdated director record can complicate banking and contract negotiations. Keeping your ACRA filings accurate and current is not just a compliance exercise; it directly affects how counterparties, banks, and regulators see your company.

How to file with the registrar, step by step
Reserve and approve your company name
Before incorporation, you must submit your proposed company name to the Registrar through BizFile+. The Registrar checks the name against existing registrations and screens for names that are identical, undesirable, or restricted. Approval is typically granted quickly if the name is distinctive and does not conflict with existing entities or reserved words. Once approved, the name is reserved while you complete the incorporation documents.
Prepare and submit incorporation documents
Incorporation requires submitting the company constitution (formerly called the memorandum and articles of association), details of directors and shareholders, the registered office address, and the share structure. At least one director must be ordinarily resident in Singapore, which means a Singapore citizen, permanent resident, or EntrePass or Employment Pass holder. Foreign founders who do not meet this requirement can appoint a nominee director to satisfy it. All documents are submitted through BizFile+ using Singpass authentication.
Receive the certificate of incorporation
Once the Registrar is satisfied that all requirements are met, the company is incorporated and a unique Unique Entity Number (UEN) is issued. This number identifies your company in all dealings with government agencies. The certificate of incorporation is issued electronically through BizFile+ and is the definitive proof that your company exists as a legal entity. There is no physical certificate mailed out; the electronic version carries full legal weight.
Update particulars whenever they change
Any change to the company's registered particulars, such as a new director, a change of registered address, or an alteration to the share structure, must be notified to the Registrar through BizFile+ within the prescribed timeframe under the Companies Act. Failing to update the register promptly is a compliance breach and can attract penalties. Your corporate secretary typically handles these updates as part of ongoing secretarial services.
File the annual return each year
Every company must file an annual return with the Registrar once a year. The annual return confirms the company's current particulars and, depending on the company's size and audit status, may need to be accompanied by financial statements in XBRL format. The filing deadline is tied to the company's financial year end, so the exact date varies by company. Late filing attracts penalties, and the Registrar publishes compliance records publicly.
Handle striking-off or winding up if needed
If a company has ceased business and has no outstanding liabilities or legal proceedings, the directors can apply to the Registrar to have the company struck off the register. The Registrar also has the power to initiate a striking-off where a company has failed to comply with statutory obligations. Striking off is distinct from a formal winding up, which involves a court process and a liquidator. For most dormant or ceased SMEs, a voluntary striking-off application through BizFile+ is the simpler route.
Benefits
One portal for all ACRA filings
BizFile+ consolidates incorporation, annual return filing, register updates, and public searches into a single online portal, so all statutory interactions with the Registrar happen in one place without needing to visit a government office.
Public register protects your credibility
Accurate, up-to-date ACRA records signal legitimacy to banks, investors, and counterparties. Third parties routinely check BizFile+ before opening accounts or signing contracts, making clean records a practical business asset.
Electronic incorporation is fast
Once documents and KYC are in order, the Registrar can incorporate a company quickly. The electronic certificate of incorporation carries full legal weight and is available through BizFile+ immediately upon approval.
Striking-off provides a clean exit
For dormant companies with no liabilities, the Registrar's voluntary striking-off process offers a straightforward, formal route to dissolve the entity without the complexity and cost of a court-supervised winding up.
When dealings with the registrar become critical
Overseas founder incorporating remotely
A foreign entrepreneur setting up a Singapore company without relocating cannot personally authenticate on BizFile+ using Singpass. They must appoint a locally resident director and engage a corporate services firm to handle the BizFile+ filings on their behalf. The Registrar's residency requirement for directors is the single most common compliance hurdle for remote incorporations. Getting this right at the outset avoids rejection and delays.
Company missing its annual return deadline
A small company that lets its annual return lapse will first receive notices from ACRA, then face late penalties, and ultimately risk the Registrar initiating a striking-off. Reinstatement after a striking-off is possible but involves additional filings and cost. Staying ahead of the annual return deadline, typically managed by a corporate secretary, is far simpler than remedying a lapsed filing.
Director change requiring a register update
When a company appoints a new director or a director resigns, the change must be filed with the Registrar through BizFile+ within the timeframe prescribed by the Companies Act. Banks and counterparties rely on the ACRA register to verify who has authority to act for the company, so an outdated director record can block account openings or contract signings until the register is corrected.
Dormant company applying for voluntary striking-off
A company that has stopped trading and has no outstanding debts or legal proceedings can apply to the Registrar for a voluntary striking-off rather than going through a formal winding up. The application is made through BizFile+ and requires the directors to confirm that the company meets the eligibility criteria. This is the most cost-efficient exit route for most dormant SMEs, and the Registrar will publish a notice before the striking-off takes effect, giving creditors an opportunity to object.
Common questions about the registrar of companies in Singapore
Is the Registrar of Companies a separate government agency in Singapore?
No. The Registrar of Companies function is carried out by ACRA (the Accounting and Corporate Regulatory Authority), a statutory board under the Ministry of Finance. There is no separate ROC office; ACRA administers the Companies Act and holds all the statutory powers associated with the Registrar role.
What is BizFile+ and who can use it?
BizFile+ is ACRA's online portal for all statutory filings and public searches. Singapore residents with a Singpass account can file directly. Foreign founders without Singpass must use an authorised local representative, such as a corporate secretary or nominee director, to submit filings on their behalf.
What happens if a company misses its annual return filing deadline?
Late filing attracts penalties from the Registrar, and persistent non-compliance can lead to the Registrar initiating a striking-off of the company. ACRA publishes compliance records publicly, so a history of late filings is visible to anyone searching BizFile+.
Can the Registrar strike off a company without the directors applying?
Yes. The Registrar has the power to initiate a striking-off where a company has failed to comply with its statutory obligations, such as repeated failure to file annual returns. This is distinct from a voluntary striking-off application made by the directors themselves.
Do I need a locally resident director to register a company in Singapore?
Yes. The Companies Act requires at least one director who is ordinarily resident in Singapore, meaning a Singapore citizen, permanent resident, or a valid pass holder such as an Employment Pass or EntrePass holder. Foreign founders who do not qualify can appoint a nominee director to satisfy this requirement.
