- The Corporations Act 2001 is the law that governs companies in Australia, administered by ASIC. If you run a Pty Ltd, it sets the rules you operate under, from how the company is internally managed to the duties you hold as a director.
- In practice it requires four things of you: govern the company under replaceable rules or a constitution, meet your director duties, keep proper financial records, and lodge and pay your ASIC obligations on time.
- Breaches carry real consequences, from ASIC late fees of A$102 to A$428 up to civil penalties and, for serious dishonest conduct, criminal liability. Most compliance failures, though, are simply missed filings.
The Corporations Act 2001 is the principal law governing companies in Australia, and it applies to your Pty Ltd from the moment it is registered. Administered by the Australian Securities and Investments Commission (ASIC), it sets out how a company is run, what its directors must do, what records it must keep, and what happens when those rules are broken.
Most business owners don’t need to read the Act cover to cover; but they do need to understand the obligations that apply to their companyf. In practice that comes down to governing the company properly, meeting your director duties, keeping records, and lodging on time.
What is the Corporations Act 2001?
The Corporations Act 2001 is the Commonwealth law that regulates companies, financial markets and financial services in Australia. For a business owner, the relevant part is the company law: the rules covering how companies are formed, governed, and wound up, and the obligations of the people who run them. ASIC is the regulator that administers and enforces it.
It is a large piece of legislation, but only a slice of it touches a small Pty Ltd day to day. The rest of this guide translates that slice into plain obligations, pairing what the Act says with what it means for your company. Think of it as the operating manual that came with your company when you registered it.
Does the Corporations Act apply to your Pty Ltd?
Yes. Every company registered with ASIC, including every proprietary limited (Pty Ltd) company, is governed by the Corporations Act. There is no small-business exemption from the Act itself; a one-person company is bound by it just as a large one is, though some obligations scale with size. The moment your company received its ACN, it became subject to these rules.
What changes with size is the depth of reporting. Most small proprietary companies are not required to prepare and lodge audited financial reports with ASIC each year, unlike large proprietary or public companies, though they must still keep proper financial records. The core governance and director-duty obligations, however, apply to your Pty Ltd regardless of how small it is.
Replaceable rules or a company constitution?
The Act says: a company’s internal management may be governed by the replaceable rules in the Corporations Act, by its own constitution, or by a combination of both (sections 134 and 135). For your Pty Ltd that means you choose how the company’s internal affairs, things like directors’ meetings, share issues and member voting, are run.
The replaceable rules are a ready-made set of governance rules built into the Act, useful if you do not want to draft your own. A constitution is your own tailored rulebook, which can adopt, modify or replace those rules. A useful detail for solo founders: under section 135, the replaceable rules do not apply to a proprietary company while the same person is both its sole director and sole shareholder, because there is no one else to govern relations with. Either way, a Pty Ltd does not lodge its constitution with ASIC, but must keep it with the company’s records.
| Replaceable rules | Constitution | |
|---|---|---|
| What it is | Default governance rules in the Act | Your own tailored rulebook |
| Cost / effort | None, built in | Drafting, often legal help |
| Best for | Simple companies | Companies wanting custom rules, investors |
| Lodged with ASIC? | N/A | No (Pty Ltd), but kept on file |
What duties does the Act place on directors?
The Act places legal duties on directors, set out in sections 180 to 184. In short, you must act with care and diligence, act in good faith and for a proper purpose, avoid misusing your position or company information, and not let the company trade while insolvent (section 588G). These apply to every director, including the sole director of a one-person company, and to de facto directors who act as directors without formal appointment.
That is the headline; the duties carry real detail and real consequences, which we cover fully in our dedicated guide to director duties. For this overview, the point is that the Act does not just regulate the company as an entity, it places personal obligations on the people running it. Meeting them is mostly a matter of reading the financials, making informed decisions, and watching solvency, rather than anything exotic.
Record-keeping and reporting you must do
The Act requires your company to keep written financial records that correctly record its transactions and financial position, and to retain them for at least seven years under the Corporations Act (note the ATO separately requires five years for tax records, so seven is the safe figure to plan around). For your Pty Ltd that means maintaining proper books, not a shoebox of receipts.
On reporting, the practical obligations for most small proprietary companies are: keep your details on the ASIC register current and notify ASIC of changes (such as a change of directors or registered office) within the required time, usually 28 days, and complete your annual review each year when ASIC issues it. Larger companies face formal financial-report lodgement, but the everyday compliance for a small Pty Ltd is keeping records straight and the register up to date.
- Keep financial records that accurately record transactions and position (7 years).
- Maintain a registered office and keep company records available.
- Notify ASIC of changes to company details, generally within 28 days.
- Complete the annual review and pay the review fee each year.
- Ensure each director holds a director ID (new directors must apply before appointment).
What happens if you breach the Act?
Consequences scale with the breach. At the everyday end, missing an ASIC deadline triggers late fees: A$102 if you are up to a month late and A$428 beyond that, and persistent failure to lodge can ultimately lead ASIC to deregister the company. These are administrative and common, the kind of thing that catches a distracted owner.
Be clear: Civil penalties can be substantial, including multi-million-dollar fines, disqualification and compensation orders. Where conduct is dishonest or reckless it becomes criminal under section 184, with a maximum of 15 years’ imprisonment. These extremes are rare, but they show the Act has teeth.
The reassuring reality is that the vast majority of compliance problems are not misconduct, they are missed filings and late fees. Keeping records straight, lodging on time and meeting your director duties keeps you well clear of the serious end.

FAQs on the Corporations Act in Australia
Does the Corporations Act apply to small companies?
Yes. Every company registered with ASIC is governed by the Act, with no exemption for being small; a one-person Pty Ltd is bound just as a large company is. What scales with size is reporting depth, most small proprietary companies need not lodge audited financial reports, but they must still keep proper records and meet director duties.
Do I need a constitution for my Pty Ltd?
Not necessarily. You can rely on the replaceable rules in the Act, adopt your own constitution, or combine both. A constitution is worth having if you want tailored governance or are bringing in investors. A Pty Ltd does not lodge its constitution with ASIC but must keep it with the company’s records if it has one.
What records does the Corporations Act require a company to keep?
Your company must keep written financial records that correctly record its transactions and financial position, retained for at least seven years under the Act. You must also maintain a registered office, keep company records available, and notify ASIC of changes to company details, generally within 28 days. Tax records are separately kept for five years for the ATO.
What are the penalties for breaching the Corporations Act?
They range widely. Missing an ASIC deadline brings late fees of A$102 or A$428, and ongoing failure can lead to deregistration. Breaching a director duty is a civil penalty matter reaching the greater of about A$1.65 million or three times the benefit gained, plus disqualification. Dishonest or reckless conduct is criminal under section 184, up to 15 years’ imprisonment.
Who enforces the Corporations Act?
The Australian Securities and Investments Commission (ASIC) administers and enforces the Corporations Act. ASIC maintains the company register, can issue infringement notices and late fees, investigate misconduct, seek civil penalties and disqualification, and refer serious matters for criminal prosecution. For most small companies, the main contact with ASIC is the routine annual review and keeping company details current.
