Understanding “what is ROC” is essential for any entrepreneur or company operating in Singapore. The Singapore Registrar of Companies (ROC) serves a pivotal role in the country’s corporate framework, overseeing business registration, monitoring compliance, and ensuring transparency in corporate governance.
In Singapore, the ROC function is administered by ACRA (Accounting and Corporate Regulatory Authority), the national regulator of business entities, public accountants, and corporate service providers.
Through ACRA, the Registrar of Companies maintains an accurate and up-to-date registry, assigns each company a unique ROC number, and provides businesses with access to official records for due diligence or legal requirements.
For companies looking to incorporate or expand operations, familiarity with the Registrar Singapore system ensures smoother registration processes, stronger regulatory alignment, and increased credibility. This guide explores the key responsibilities of the Registrar of Companies and how its systems directly support the ease of doing business in Singapore.
Overview of ROC and ACRA in Singapore
What does ROC mean in Singapore?
The Registrar of Companies Singapore (ROC) is the official government function responsible for supervising company incorporation, maintaining corporate records, and ensuring business compliance.
Unlike some jurisdictions where this role is handled by a distinct registrar, in Singapore, the Registrar of Companies is effectively represented by ACRA—the Accounting and Corporate Regulatory Authority. Therefore, when businesses mention the Singapore Registrar of Companies, they are referring to ACRA acting in its regulatory role over corporate entities.
Understanding ACRA’s background and authority
The Accounting and Corporate Regulatory Authority (ACRA) was established in 2004 through the merger of the Public Accountants’ Board (PAB) and the Registry of Companies and Businesses (RCB). Its creation marked a significant step in consolidating the regulatory framework for businesses and accounting practices in Singapore.
In 2023, ACRA’s authority was further reinforced by integrating the Singapore Accountancy Commission (SAC) and the Accounting Standards Council (ASC). This move expanded ACRA’s role in developing the accountancy sector and overseeing the formulation of national accounting standards.
Due to this consolidated structure, “ACRA” and “Registrar of Companies” are often used interchangeably when referring to business registration and compliance in Singapore.
Core responsibilities of ACRA as ROC
As the registrar Singapore relies on for corporate governance, ACRA carries out a broad range of regulatory and administrative duties:
- Company Registration and Incorporation: Through the BizFile+ portal, ACRA streamlines the process of forming new business entities in Singapore.
- Maintenance of Corporate Records: ACRA keeps a public repository of company data, accessible for transparency and due diligence.
- Ensuring Business Compliance: It monitors companies’ statutory obligations under the Companies Act.
- Enforcement of Corporate Regulations: ACRA has the authority to impose penalties and take legal action against non-compliant entities.
In short, understanding the ROC’s meaning and ACRA’s functions is essential for any entity looking to operate legally and successfully in Singapore.
Business structures registered under ROC
Singapore’s Registrar of Companies (ROC), operated by ACRA, recognizes multiple business structures to suit various operational needs and ownership models. Each structure has distinct legal implications, liability considerations, and compliance obligations.
Below is a comparative summary of key business types registered under the ROC:
| Business Type | Description | Key ROC Requirements |
|---|---|---|
| Sole Proprietorship | Owned by a single individual with unlimited personal liability | Simple registration; owner assumes full legal and financial responsibility |
| Partnership | Includes General, Limited, and Limited Liability Partnership (LLP) formats; liability varies by type | Registration with ACRA; LLPs require a registered manager |
| Private Limited Company | Separate legal entity, preferred for SMEs and startups | At least one local director must appoint a company secretary |
| Public Limited Company | Can offer shares to the public and list on Singapore Exchange (SGX) | Subject to high disclosure, audit, and compliance standards |
| Branch Office / Subsidiary | Set up by foreign companies to operate locally | Requires local representative; compliance with local business laws |
Choosing the correct structure depends on your goals and risk appetite. Learn more about the various types of companies in Singapore to make an informed decision for your business.

ROC compliance essentials for businesses
Once your business is registered with the Singapore Registrar of Companies (ROC), you must fulfill several legal obligations to maintain good standing under ACRA’s regulatory framework.
Common compliance requirements
- Annual Filing Obligations
Every company must file an Annual Return within 30 days of its Annual General Meeting (AGM), and hold the AGM within prescribed timeframes—typically within 6 months after the financial year‑end (first AGM within 18 months of incorporation, subsequently no more than 15 months apart).
- Registered Office & Company Secretary
You must maintain a registered office in Singapore and appoint a company secretary within six months of incorporation. The secretary cannot be the sole director if only one director is appointed.
This role is critical to filing returns, maintaining statutory registers, and ensuring compliance. For professional assistance, check out our guideline for company secretary in Singapore.
- Accurate Record-Keeping
Companies must keep proper accounting records, corporate registers, and updated company details—such as changes in directors, shareholders, or registered address—and submit these to ACRA promptly (typically within 14 days of a change).
Penalties and enforcement by the ROC
- Late Filing Penalties & Fines
Non-compliance with AGM or Annual Return deadlines incurs fixed composition sums—typically SGD 300 per breach—and can escalate to fines up to SGD 5,000 per offence or summons for prosecution if not settled.
- Director Disqualification and Debarment
Directors convicted of three or more filing offences within five years may be disqualified from serving on boards for five years. Prolonged non-compliance (three continuous months) can lead to debarment, barring individuals from serving as directors or secretaries of any company.
- Striking Off & ROC Number Importance
Persistent failure to meet obligations can result in the company being struck off. Maintaining a valid ROC number and company in good standing is essential for legal operation and reputation in Singapore’s regulatory ecosystem.

Frequently Asked Questions
Can I process corporate services online in Singapore?
Yes. Through Bizfile+ Singapore, you can submit company registrations, update business details, file annual returns, and request public documents—all digitally via ACRA’s portal, eliminating in‑person visits to the Registrar of Companies Singapore.
Is ROC number the same as UEN (Unique Entity Number)?
No. The ROC number refers to the identifier issued by the Registrar of Companies, i.e. ACRA. The UEN is the standard business registration number assigned to companies and other entities in Singapore. While all companies must register with the Singapore Registry of Companies and businesses, the ROC number itself and the UEN serve different purposes.
Can foreign companies get an ROC number?
Foreign companies setting up in Singapore, such as branch offices, can obtain a UEN upon registration with ACRA. However, a standalone ROC number is not issued separately. Once registered, these entities must comply with the same governance obligations as local companies under the Registrar of Companies regime.
Where can I access ROC documents?
You can retrieve public documents—such as business profiles, annual returns, and certificate of incorporation—via ACRA’s BizFile+ portal. These documents are accessible to the public for transparency and due diligence, and can be purchased directly through the portal.
