How to Register a Company in Australia: Step-by-Step Guide — 2026 AU Guide
Registering a company in Australia takes as little as one business day when you apply through the Australian Securities and Investments Commission (ASIC) online portal, with standard registration fees starting from $597 AUD in 2026. Most applicants need an Australian Business Number (ABN), a registered office address, and at least one director who ordinarily resides in Australia before they begin the process.

Why Register a Company in Australia?
Choosing to operate as a registered company — rather than as a sole trader or partnership — provides significant legal and financial benefits. A proprietary limited company (Pty Ltd) creates a separate legal entity, meaning your personal assets are generally protected if the business faces debts or legal action. This structure also makes it easier to attract investors, hire staff under formal agreements, and scale operations over time.
According to the Australian Bureau of Statistics (ABS), there were approximately 2.6 million actively trading businesses in Australia as of 2024–25, with proprietary limited companies making up the fastest-growing segment of new registrations. The shift towards formal company structures reflects growing awareness of liability protection and tax planning opportunities.

Understanding the Types of Companies in Australia
Before you register, you need to decide which company type suits your situation. The most common structures are:
Proprietary Limited Company (Pty Ltd): The most popular choice for small to medium businesses. It can have up to 50 non-employee shareholders and cannot raise funds from the general public. Public Company (Ltd): Suited to larger enterprises that want to list on the ASX or raise public capital. These face significantly higher compliance requirements. Company Limited by Guarantee: Typically used by not-for-profit organisations and charities. Members agree to contribute a defined amount if the company is wound up rather than holding shares.For the vast majority of Australian entrepreneurs and small business owners, a Pty Ltd is the correct starting point. This guide focuses primarily on that structure.

What You Need Before You Apply
Gathering the right information before you start your application prevents delays and avoids the frustration of having to restart partway through the ASIC process. Here is what you will need:
- Company name: Conduct a name search on the ASIC Connect portal to confirm it is available. Your name must not be identical or deceptively similar to an existing registered company or trademark. - Registered office address: This must be a physical Australian street address (not a PO Box) where official documents can be served during business hours. - Director details: Full legal name, date of birth, residential address, and consent to act as director. At least one director must ordinarily reside in Australia. - Shareholder details: Names, addresses, and the number and class of shares each person will hold. - Share structure: Decide how many shares to issue, at what nominal value, and whether they will be ordinary or different classes. - Australian Business Number (ABN): While you can register your company before obtaining an ABN, applying for both simultaneously through the Australian Business Register (ABR) saves time.

Step-by-Step: How to Register Your Company
Step 1 — Choose and search your company name Visit the ASIC Connect name availability search tool. Once you have confirmed availability, you may optionally reserve the name for two months for a small fee while you complete the rest of your preparation. Step 2 — Prepare your company constitution (or rely on the replaceable rules) ASIC's replaceable rules act as a default internal rulebook if you do not adopt a formal constitution. For simple structures with a single director-shareholder, the replaceable rules are often sufficient. More complex ownership arrangements benefit from a tailored constitution drafted by a solicitor. Step 3 — Submit your application via ASIC Connect Complete Form 201 (Application for Registration as an Australian Company) online. You will provide all director, shareholder, and registered office details here. The standard processing time is one business day for online applications. Step 4 — Receive your ACN and Certificate of Registration Once approved, ASIC issues your Australian Company Number (ACN) and a Certificate of Registration. These are sent digitally via the ASIC Connect portal. Step 5 — Apply for your ABN, TFN, and GST registration Apply for your Australian Business Number and Tax File Number through the Australian Business Register at business.gov.au. If you expect annual turnover to exceed $75,000 AUD, you are also required to register for Goods and Services Tax (GST) — a threshold the ATO confirmed remains unchanged for 2026. Step 6 — Open a business bank account Your ACN and Certificate of Registration will be required by most Australian banks to open a business transaction account in the company's name. Step 7 — Meet your ongoing ASIC obligations All registered companies must pay an annual review fee to ASIC, lodge an annual statement confirming company details, and maintain accurate registers of members and officers.---

Common Mistakes to Avoid
Even straightforward registrations can run into problems. Watch out for these frequent errors:
- Choosing a name too similar to an existing brand: ASIC may reject your application, or you could face a trademark dispute later. Always check both the ASIC register and IP Australia's trade mark database. - Using a residential address you do not want public: Your registered office address is listed on the public ASIC register. Many service providers offer a registered office address service for around $99–$199 per year. - Not issuing shares correctly at the time of registration: Shares must be formally issued and a share register maintained from day one. - Forgetting director consent forms: Every director must sign a consent to act before or immediately after registration.

Your Ongoing Compliance Obligations
Registration is just the beginning. Once your company exists, ASIC and the ATO impose ongoing obligations:
- Annual review fee: Payable to ASIC each year on the anniversary of your registration (currently $310 AUD per year for a proprietary company in 2026). - Annual solvency resolution: Directors must pass a solvency resolution each year confirming the company can pay its debts as they fall due. - Updating ASIC within 28 days: Any changes to directors, shareholders, or the registered office must be lodged with ASIC promptly. - Tax lodgements: Company tax returns are lodged with the ATO annually. The base company tax rate is 25% for small base rate entities with aggregated turnover under $50 million.

Frequently Asked Questions
Q: How long does it take to register a company in Australia? A: Online applications submitted through ASIC Connect are typically processed within one business day. Using a professional service does not usually add significant time, though bespoke legal work may extend the process to several days. Q: Can a foreigner register a company in Australia? A: Yes, foreign nationals can be shareholders in an Australian company. However, at least one director must ordinarily reside in Australia. Foreign-controlled companies may also have additional obligations under the Foreign Investment Review Board (FIRB) framework. Q: Do I need a lawyer to register a company? A: Not for a straightforward Pty Ltd registration. Most sole founders or two-partner businesses successfully register using ASIC's online portal or an online service. Legal advice becomes important when there are multiple shareholders, complex shareholding arrangements, or a detailed shareholders' agreement is required. Q: What is the difference between an ABN and an ACN? A: Your Australian Company Number (ACN) is a unique nine-digit number assigned by ASIC to your company. Your Australian Business Number (ABN) is an eleven-digit identifier issued by the ATO for tax and business purposes. All companies should hold both, though your ABN incorporates your ACN within it.---
