The Companies Act is the law behind every Singapore company. It took effect on 29 December 1967, ACRA administers it, and the full text is free on Singapore Statutes Online. For a small owner, the parts that bite are director duties, the registers, annual filings and what happens when the company closes.
Checked against ACRA's Companies Act page and Singapore Statutes Online listings.
What is the Companies Act?
It is the statute that governs companies from incorporation to winding up. ACRA's legislation page says the Act came into effect on 29 December 1967 and was based on the Companies Act of Malaysia from . ACRA is the regulator that administers it, so most of your interaction with the law happens through Bizfile.
The Act applies to local companies and to foreign companies for their operations in Singapore. A sole proprietorship or partnership sits under different rules. See our comparison of company, sole proprietorship and LLP.
Where do you read it?
Go to Singapore Statutes Online at sso.agc.gov.sg and search for the Companies Act. It is free, updated and searchable by section. Subsidiary legislation sits on the same site, including the filing of documents regulations. ACRA's page also lists regulations on the register of controllers and the transfer of registration. Our checks could not load the statute pages automatically, so read key sections on SSO yourself before you rely on them.
What are the main amendments?
ACRA's page lists three.
| Change | What ACRA says it did |
|---|---|
| amendment act | The largest overhaul since 1967: directors' duties, shareholder rights, capital maintenance, accounts and audit, company administration |
| amendment act | Added inward re-domiciliation, beneficial ownership rules and AGM exemptions for private companies |
| change | Exempted certain entities from keeping some registers |
The act went live in two phases. Phase one started on and carried about 40% of the more than 200 amendments. The rest came in the first quarter of .
Which rules matter most to a small company?
Most owners meet six areas of the Act.
- Directors. The statute says a director must act honestly and use reasonable diligence. Who can serve is in our director requirements.
- Company secretary. Appoint one within six months. See the secretary qualifications.
- Constitution. The company's rule book. See the constitution guide.
- Registers. Members, directors, secretaries and controllers. See the register of directors, register of members and registrable controllers pages.
- Annual filing. The annual return and general meeting rules. See annual return and AGM.
- Closing the company. Strike off or winding up. See strike off.
Penalties vary by section. ACRA publishes offences and penalties for companies, and we quote the figures we verified on each topic page rather than listing them all here.
Does the Act apply to a private company the same way as a public one?
No. Public companies carry heavier duties, and listed companies add stock exchange rules and the corporate governance code. A private company limited by shares can have up to 50 members and has lighter filing duties. See company types in Singapore and the governance code guide.
How do you stay on the right side of it?
Keep a calendar. Registers must be updated, officer changes filed within 14 days, and annual obligations met. Many founders hand this to a corporate secretary. Ours is an independent guide, not a law firm, and nothing here is legal advice. When a rule affects a big decision such as a share issue or a director dispute, read the section on SSO and speak to a Singapore lawyer.
