The Singapore Companies Act Explained: A Plain-English Guide for SME Directors (2026)
By Lucas Seah, Founder of Excellence Singapore Group | Last Updated: June 2026
The Companies Act 1967 is the main law that governs how companies are formed, run, and wound up in Singapore. It sets out who can be a director, what a company secretary must do, how accounts and financial statements are kept, when meetings and filings are due, and the penalties for getting it wrong. Formerly the Companies Act (Chapter 50), it was renamed in the 2020 Revised Edition.
This guide explains the Act in plain English for SME directors: what it is, which companies it covers, the core obligations mapped to their sections, and the recent 2025 changes you should know about.
Key Takeaways
- The Companies Act 1967 is Singapore’s primary company law, administered by ACRA, and applies to companies incorporated here (not to sole proprietorships, partnerships, or LLPs, which fall under other Acts).
- It was formerly cited as the Companies Act (Cap. 50). The 2020 Revised Edition renamed it to the Companies Act 1967, so both names refer to the same law.
- Core director obligations include keeping at least one ordinarily resident director (s145), appointing a company secretary within 6 months (s171), holding an AGM (s175), and filing the annual return (s197).
- Section 157 requires every director to act honestly and use reasonable diligence; section 156 requires disclosure of conflicts of interest.
- The Corporate and Accounting Laws (Amendment) Act 2025 was passed on 5 November 2025, with the first tranche of provisions commencing 6 May 2026, and it raises the maximum fine for a breach of director duties from S$5,000 to S$20,000.
What is the Singapore Companies Act?
The Companies Act 1967 is the statute that regulates companies in Singapore from the day they are incorporated to the day they are struck off or wound up. It is administered by the Accounting and Corporate Regulatory Authority (ACRA), and it came into effect on 29 December 1967. In ACRA’s own words, it governs companies “from incorporation, management, operations, director duties, to winding up procedures”.
In practice, the Act answers the questions an SME director keeps running into. Who must sit on the board? When is the annual general meeting due? What records must the company keep? What happens if a director acts dishonestly? The full text sits on Singapore Statutes Online, the official government legislation portal, where every section can be read for free.
You do not need to memorise the Act. You do need to know which obligations apply to your company and when, because ACRA enforces them and the directors, not the company alone, carry personal liability for many of the breaches.
Is it the Companies Act Cap 50 or 1967?
It is both names for the same law. The Act was historically cited as the Companies Act (Chapter 50), often shortened to Cap. 50. As part of the 2020 Revised Edition of Singapore’s Acts of Parliament, which came into force on 31 December 2021, the Law Revision Commission dropped chapter numbers and began referring to each Act by its name and year of enactment. So “Companies Act (Cap. 50)” became simply the “Companies Act 1967”.
This trips up SMEs constantly. An older lawyer’s letter, a bank form, or a 2018 template may still say “Cap. 50”, while a fresh ACRA notice says “Companies Act 1967”. They are not two different laws and nothing in your obligations changed because of the rename. If a document cites a section number, the section number is what matters, not the chapter label in front of it.
Which companies does the Companies Act apply to?
The Act applies to companies incorporated in Singapore, which for most SMEs means the private company limited by shares (the “Pte Ltd”). It also covers public companies, companies limited by guarantee, and foreign companies registered to carry on business here. Different obligations switch on depending on the type: a private company has lighter requirements than a listed public company, for example on AGM and annual return deadlines.
What the Companies Act does not cover is just as important. A sole proprietorship and a general partnership are registered under the Business Names Registration Act, and a limited liability partnership (LLP) sits under the Limited Liability Partnerships Act. Those structures are not companies, so the director duties, the AGM, and the financial-statement rules in the Companies Act simply do not apply to them. If you are choosing a structure, our guide on how to check if a company is registered in Singapore shows how to tell what a registered entity actually is.
What does the Companies Act actually require?
The Act runs to hundreds of sections, but for a typical SME the obligations that matter compress into ten. Here is the practitioner’s shortlist we walk new directors through, each mapped to its section so you can read the source yourself.
| Obligation | Section | Deadline or trigger |
|---|---|---|
| At least one ordinarily resident director | Section 145 | From incorporation; the post must never be left vacant |
| Appoint a company secretary | Section 171 | Within 6 months of incorporation; not vacant beyond 6 months |
| Maintain a registered office in Singapore | Section 142 | From incorporation; a local address for official notices |
| Keep proper accounting records | Section 199 | Throughout; retain for at least 5 years |
| Present financial statements | Section 201 | At the AGM; true and fair, prepared under SFRS |
| Hold an annual general meeting (AGM) | Section 175 | Within 6 months of FYE (private); 4 months (listed) |
| File the annual return | Section 197 | Within 7 months of FYE (private); 5 months (listed) |
| Act honestly and use reasonable diligence | Section 157 | At all times; breach is a criminal offence |
| Disclose conflicts of interest | Section 156 | As soon as the director becomes aware |
| Maintain a register of registrable controllers (RORC) | Part 11A (s386AA on) | From incorporation; keep beneficial owner details current |
A few of these deserve a closer look because they are where SMEs slip.
One resident director (s145). Every company must have at least one director who is ordinarily resident in Singapore. If your only local director resigns, the company is in breach until a replacement is in place, which is why a director change needs planning, not a same-day filing. Our guide on changing or resigning a director in Singapore covers the mechanics.
A company secretary within six months (s171). The company secretary post cannot stay vacant for more than six months, and a sole director cannot also be the sole company secretary. We cover that specific rule in can a sole director be the company secretary.
Proper accounting records (s199) and financial statements (s201). Records must be kept for at least five years and must support a true and fair set of financial statements prepared under the Singapore Financial Reporting Standards. Which standard applies depends on your company, which we explain in Singapore Financial Reporting Standards (SFRS) explained. Whether those statements then need an audit turns on the small company test in our audit exemption guide.
Director duties under section 157
Section 157 is the heart of the Act for directors. It requires a director to “act honestly and use reasonable diligence in the discharge of the duties of his office”, and it bars a director from making improper use of company information or position for personal gain. A breach is a criminal offence under section 157(3), currently carrying a fine of up to S$5,000 or imprisonment of up to one year, alongside a separate civil claim by the company for any loss.
Sitting next to it, section 156 requires a director to disclose any conflict of interest, including an interest in a transaction the company is entering into. Non-disclosure is also an offence, with a fine of up to S$5,000 or imprisonment of up to twelve months.
These duties apply to every director equally, including a non-executive or a nominee director. “I left it to my co-director” is not a defence. For the fuller picture, see our guide to the key responsibilities of a director in a Singapore private limited company. A clear company constitution helps here too, by setting how the board makes decisions, as we explain in what a business constitution is and why it matters.
What recent changes were made to the Companies Act?
The most significant recent change is the Corporate and Accounting Laws (Amendment) Act 2025. It was passed by Parliament on 5 November 2025, and ACRA has confirmed the first tranche of provisions commences on 6 May 2026.
The headline change for directors is the penalty. The maximum fine for a breach of director duties rises from S$5,000 to S$20,000, and in serious cases involving negligence or wilful failure to act in the company’s best interests, a director can face up to twelve months’ imprisonment. The Act also tightens transparency, requiring companies to disclose the nominators behind nominee directors and shareholders, not just the nominees themselves. We cover the penalty change in detail in our post on the S$20,000 directors’ fine and what the 2026 ACRA amendment changes.
The practical takeaway is that the cost of a careless breach is going up. Obligations that an SME could once treat as low-risk paperwork now carry a materially larger downside.
How the Companies Act connects to your other filings
The Act is not a standalone document you read once. It drives the compliance calendar you live by every year. Section 175 sets the AGM deadline (within six months of the financial year end for a private company), and section 197 sets the annual return deadline (within seven months for a private company). ACRA no longer offers an informal grace period on these, as we explain in ACRA removing the grace period on AGM and annual return deadlines, so the statutory dates are now the real dates.
The AGM itself is where the section 201 financial statements are laid before members, unless the company is exempt or has dispensed with the AGM. Our annual general meeting guide sets out who must hold one and how. When two companies combine, that too is a Companies Act process, the statutory amalgamation, which we break down in company amalgamation in Singapore.
Keeping all of this on track is exactly what a company secretary is for. The secretary tracks the deadlines, prepares the resolutions, and lodges the filings, which is why section 171 makes the appointment mandatory in the first place.
Key Takeaway: The Companies Act 1967 (formerly Cap. 50) is the single law tying together your directors, your secretary, your accounts, your meetings, and your ACRA filings. Get the ten core obligations right and the rest of your compliance falls into place.
