The Registrar of Companies is part of ACRA
The Registrar of Companies in Singapore is not a separate agency. The function sits within the Accounting and Corporate Regulatory Authority (ACRA), the statutory body established under the Accounting and Corporate Regulatory Authority Act. ACRA administers the Companies Act, the Business Names Registration Act, and several other pieces of legislation that govern business entities in Singapore. When people refer to the "ROC" or the "Registrar", they mean this function within ACRA. The Registrar holds the authority to incorporate companies, approve or reject company names, maintain the public register of business entities, and take enforcement action against non-compliant companies. For a fuller picture of what ACRA does across all its regulatory responsibilities, see Singapore's corporate regulator explained.
Core functions the Registrar carries out
The Registrar's responsibilities span the full lifecycle of a Singapore company. At the start, the Registrar reviews and approves company names, then formally incorporates the company and issues a Unique Entity Number (UEN) - the identifier that follows the company through every government interaction. You can read more about what a UEN is and how it works on the UEN number guide. During a company's active life, the Registrar maintains the public register, which records directors, shareholders, the registered office address, and the company constitution. Anyone can search this register through BizFile+. The Registrar also processes changes to these particulars when companies file updates. At the end of a company's life, the Registrar has the power to strike off entities that are no longer carrying on business or that have failed to meet their statutory obligations - a process that can be initiated by the company itself or by ACRA acting on its own motion.
Statutory compliance obligations the Registrar enforces
Ongoing compliance is where most companies feel the Registrar's presence most directly. Under the Companies Act, every Singapore company must file an annual return with ACRA - a yearly confirmation that the company's registered particulars are current and accurate. Companies that hold Annual General Meetings (AGMs) must do so within the prescribed timeframe and file the return after that. Companies exempt from holding an AGM still have an annual return filing deadline to meet. Late lodgement attracts penalties, and persistent non-compliance can escalate to enforcement action against directors and, ultimately, to the company being struck off the register. The Registrar also enforces requirements around financial statements: companies must prepare accounts that meet the prescribed standards and, where required, file them as part of the annual return. For companies with corporate tax obligations, the annual return filing with ACRA runs alongside separate filings with the Inland Revenue Authority of Singapore (IRAS) - see the corporate tax rates guide for context on those.
BizFile+ is how you interact with the Registrar
Virtually all interactions with the Registrar happen through BizFile+ (bizfile.gov.sg), ACRA's online filing and information portal. Through BizFile+, a company can incorporate a new entity, reserve a company name, update registered particulars, file annual returns, submit changes in directors or shareholders, and retrieve publicly available corporate information on any registered entity. Access to BizFile+ requires a Singpass login for individuals based in Singapore. Foreign entrepreneurs who do not hold a Singpass typically work through a registered filing agent - a corporate service provider authorised to file on their behalf. A director can also appoint and replace a company secretary directly through BizFile+. The government filing fees are the same whether the company files itself or uses a filing agent; what the agent provides is the expertise to get the filing right the first time and the accountability to track deadlines.
What happens when a company falls behind on filings
Missing ACRA deadlines is not a minor administrative inconvenience. Late lodgement penalties accrue on overdue filings, and the longer a company waits, the larger the penalty exposure. A company can apply to ACRA for a waiver or refund of penalties, but the outcome is at ACRA's discretion and the application process requires documenting the reasons for the late filing, with supporting evidence, for each financial year that is outstanding. ACRA typically takes several weeks to review such applications. Beyond penalties, persistent non-compliance puts the company at risk of being struck off the register, which has consequences for directors and shareholders alike. The practical lesson: catching up is always cheaper than letting arrears accumulate. Companies in this position should also look at their corporate secretarial services arrangements, since a qualified company secretary's primary job is to make sure these deadlines are never missed in the first place.
Every Singapore company's life begins and ends with the Registrar, and the obligations in between are continuous, not optional.
How to file with the Registrar of Companies
Confirm what you need to file
Before logging into BizFile+, work out exactly what filing is required. Common filings include the annual return, changes to directors or shareholders, updates to the registered office address, and changes to the company name or constitution. Each filing type has its own form, its own ACRA fee, and its own deadline. Mixing these up or filing the wrong form wastes time and can attract unnecessary fees. If you're unsure, the corporate secretarial services page covers what a company secretary handles on your behalf.
Log in to BizFile+ with Singpass
Go to bizfile.gov.sg and log in using your Singpass credentials. Singpass is required for all authorised filers, including directors and company secretaries acting for the company. If you are an overseas founder without a Singpass, you cannot file directly and will need to work through a registered filing agent. Ensure the person logging in has the correct authorisation level for the filing they intend to submit.
Complete the relevant form and review the details
Select the appropriate transaction from the BizFile+ menu. Fill in all required fields carefully: errors in company particulars, officer details, or financial year dates can cause a filing to be rejected or, worse, to be accepted with incorrect information on the public register. Double-check every field before submitting, particularly UEN, officer identification numbers, and dates. For annual returns, confirm that the financial statements attached (where required) match the period being reported.
Pay the ACRA filing fee
Most ACRA filings attract a government fee, payable at the point of submission through BizFile+. The fee is the same regardless of whether the company files itself or through a filing agent. Payment is typically made by credit card or via GIRO. Keep the payment confirmation and the filing acknowledgement that BizFile+ generates - these are your evidence that the filing was submitted on time.
Verify the update on the public register
After a successful filing, ACRA updates the public register, usually within a short processing window. Log back into BizFile+ and search for your company to confirm that the change is reflected correctly. For incorporations, this is also when your Unique Entity Number (UEN) is issued and the company formally comes into existence. If anything looks wrong on the register, contact ACRA promptly to request a correction.
Track the next deadline before you log out
Every filing closes one obligation and often opens the clock on the next. After filing your annual return, note the date by which next year's return must be filed. After an AGM, record the next AGM deadline. A missed deadline with ACRA means penalties, and the Registrar does not send reminders. A company secretary's core job is maintaining exactly this kind of deadline calendar - see corporate secretarial services for how that works in practice.
Benefits
One register, publicly searchable
The Registrar maintains a public register of all Singapore business entities, meaning anyone can verify a company's directors, shareholders, registered address, and filing status through BizFile+. This transparency underpins commercial trust in Singapore.
Incorporation can happen within a day
For straightforward applications where the company name is approved and all documents are in order, the Registrar can process an incorporation and issue a UEN on the same day. Speed depends on the completeness of the submission.
Penalty waiver applications are possible
Companies that have incurred late-filing penalties can apply to ACRA for a waiver or refund. The application is reviewed on its merits, with the reason for the late filing and supporting documents assessed by ACRA, typically within several weeks.
Filing agents can act on your behalf
Registered filing agents, including corporate service providers, can submit filings to the Registrar on a company's behalf. This is particularly useful for overseas founders without Singpass access and for companies that want a qualified professional managing their compliance calendar.
Situations where the Registrar's role becomes real
Foreign founder incorporating remotely
An overseas entrepreneur setting up a Singapore company cannot log into BizFile+ without a Singpass, which requires a Singapore-issued identity document. In practice, this means the incorporation filing must go through a registered filing agent. The agent submits the application, the Registrar reviews the proposed company name and the incorporation documents, and - if everything is in order - issues the UEN and the incorporation notice, often within a day. The founder never needs to be physically present. See company registration for how this process works end to end.
Company with overdue annual returns
A small company that missed one or more annual return deadlines faces both accrued penalties and the risk of the Registrar initiating a strike-off. The path back to good standing involves filing all outstanding returns, paying the penalties, and potentially applying to ACRA for a penalty waiver with supporting documentation. ACRA takes several weeks to review waiver applications, and the outcome is not guaranteed. Getting a qualified company secretary in place immediately is the most reliable way to prevent the situation from recurring.
Director change after a resignation
When a director resigns, the change must be filed with the Registrar through BizFile+ within the prescribed timeframe. Until the update is lodged, the departing director remains on the public register - which matters for their personal liability exposure. The filing requires the incoming or remaining directors to submit the change, not the outgoing director. A company secretary handles this as a routine matter, and it falls within the standard scope of secretarial services.
Company name approval before incorporation
Before a company can be incorporated, the Registrar must approve the proposed name. ACRA will reject names that are identical or too similar to an existing registered name, names that are misleading about the company's nature, and names that are contrary to public interest. A name can be reserved for a short period while the incorporation documents are prepared. If the name is rejected, an alternative must be proposed before the process can continue. This step is easy to overlook when founders are focused on the bigger picture of getting the company set up.
Common questions about the Registrar of Companies
Is the Registrar of Companies a separate body from ACRA?
No. The Registrar of Companies function sits within ACRA - the Accounting and Corporate Regulatory Authority. ACRA administers the Companies Act and carries out the Registrar's statutory responsibilities. When you file with the Registrar, you are filing with ACRA through BizFile+.
What does the Registrar's public register actually show?
The public register maintained by the Registrar shows a company's UEN, registered name, registered office address, business activity, directors, shareholders, company secretary, and filing history. Anyone can search this information through BizFile+ without needing a Singpass login for basic searches. This is why keeping your company's particulars current with ACRA matters - what's on the register is what counterparties and banks will see.
What happens if the Registrar strikes off my company?
A strike-off removes the company from the register, effectively dissolving it. This can be initiated by the company voluntarily or by ACRA when a company has persistently failed to meet its statutory obligations. Once struck off, the company ceases to exist as a legal entity, and its assets may vest in the Government. Directors of struck-off companies can also face restrictions. Restoration is possible but involves a court process.
Can I file with the Registrar myself, or do I need a filing agent?
Singapore-resident directors with Singpass can file directly through BizFile+. Overseas founders without Singpass must use a registered filing agent - a corporate service provider authorised to submit filings on their behalf. The government fees are identical either way; the filing agent provides expertise and deadline management, not a cheaper route to ACRA.
What is the annual return and when must it be filed?
The annual return is a statutory filing with ACRA that confirms a company's registered particulars are up to date and, for companies that must hold an AGM, that the AGM has been held. The filing deadline is tied to the company's financial year end, and late lodgement attracts penalties. A company secretary tracks this deadline and handles the filing as part of their standard responsibilities. See corporate secretarial services for how this is managed in practice.
