Australia is a great place to do business. Most people know that. What they do not always know is that the registration process has more moving parts than it looks, and missing even one document can push your timeline back by weeks.
The good news is that none of this is complicated once you know what to expect. Setting up a company in Australia means working with two government bodies: ASIC handles company registration, and the ATO handles your tax setup. Get your documents sorted for both, and the process moves quickly. Show up unprepared, and it stalls.
Here is exactly what you need.
Before Anything Else, Decide on Your Structure
This is the step people skip, and it causes problems later. Your business structure determines which documents apply to you.
- Sole Trader: Least paperwork, but you and the business are legally the same. Every debt is yours personally
- Partnership: Two or more people running a business together. You will need a partnership agreement that everyone has actually read and signed
- Proprietary Limited Company (Pty Ltd): The most common choice, locally and for international businesses. You are protected by limited liability and the company exists as its own legal entity
- Branch of a Foreign Company: Lets an overseas business operate in Australia without forming a brand new local entity
Most people go with Pty Ltd. It is credible, structured, and built for growth. The rest of this guide focuses on that structure.
The Documents You Need to Register
1. Identity Documents for Every Director and Shareholder
ASIC needs to verify who is behind the company. Every director and shareholder must provide valid ID, no exceptions. A passport works for everyone. Australian residents can also use a driver’s license or government-issued ID. The key word is valid. An expired passport sitting in someone’s drawer has derailed more than a few applications. Collect these early, especially if your directors are in different countries.
2. Director Consent to Act (Form 190)
Every director signs this to confirm they actually know they are being appointed, they accept the legal responsibilities that come with the role, and they are not legally disqualified from managing a company in Australia. It sounds procedural because it is. But ASIC will not move forward without a signed copy from each director, so do not treat it as an afterthought.
3. Application for Registration (Form 201)
This is the main form. It covers your company name, registered office, principal place of business, director and secretary details, shareholder information, and how shares are structured. Fill it out carefully. Details that contradict each other across different sections are the number one reason ASIC sends applications back. Double check everything before you hit submit.
4. Company Name Search and Confirmation
Check your preferred company name through ASIC’s online search before you do anything else. It cannot be identical or confusingly similar to an existing registered name. Words like “bank,” “trust,” and “government” require special approval to use. Have a backup name or two ready because first choices do not always clear, and you do not want to pause everything while you rethink your branding.
5. Constitution or Replaceable Rules
Think of this as your company’s internal rulebook. It covers how decisions get made, what rights shareholders have, and what happens when people disagree. You have two options here:
- Replaceable Rules: These come built into the Corporations Act 2001. Fine for a simple structure with no complicated arrangements
- Custom Constitution: Worth the effort if you have multiple shareholders, investors involved, or anything about your setup that is not completely standard
If you go custom, get it drafted before you start the application. A lawyer is a good idea here. It is one of those documents people cut corners on early and then wish they had not.
6. Proof of Registered Office Address
Your company needs a real, physical address in Australia. Not a P.O. box. Someone needs to be reachable there during normal business hours for official correspondence. It can be your actual office, a law firm’s address, or a virtual office that meets ASIC’s requirements. Confirm compliance before you list it. Finding out later that the address does not qualify is an easy problem to avoid.
7. Shareholder Details and Share Records
ASIC needs to know who owns the company, how much they own, and in what form. For each shareholder you need their full legal name, address, number of shares, share class, and the amount paid per share. Australia allows 100% foreign ownership of private companies, which is one reason it attracts so many international founders. If your business touches sectors like agriculture or telecommunications, check with the Foreign Investment Review Board before proceeding.
8. Director Identification Number
This one catches people off guard because it is a newer requirement. Every director must have a Director ID issued through the Australian Business Registry Services before being appointed. It is tied to the individual, not the company, and it exists to prevent fraud and identity misuse in corporate structures. Apply for it early. Processing is not always instant.
Tax Registrations Right After You Incorporate
The moment ASIC issues your Australian Company Number, start on these:
- Tax File Number (TFN): Apply through the ATO straight away. You need it to lodge returns and handle anything financial with the government
- Australian Business Number (ABN): Required to invoice clients legally, claim GST credits, and work with suppliers and agencies. Apply through the Australian Business Register using your new ACN
- GST Registration: Mandatory once annual turnover hits AUD 75,000. You can register voluntarily before that if it makes sense for how your business operates
Hiring Staff? A Few More Things
Setting up a company in Australia with employees adds another layer. You will need to register for PAYG withholding so you can send employee income tax to the ATO correctly. You also need superannuation details sorted before your first payroll since employer contributions are mandatory. And WorkCover insurance is required in every state and territory the moment someone is on your payroll.
The Mistakes Worth Knowing About
These are small things that create big delays:
- Expired ID documents, found out only after submission
- Mismatched details between Form 201 and identity documents
- A P.O. box listed as the registered office
- Directors who have not yet obtained their Director ID
- Assuming an existing sole trader ABN transfers to a new Pty Ltd. It does not
Run a checklist before you submit. It takes ten minutes and saves weeks.
Ready to Move Forward
The documents themselves are not the hard part. Knowing which ones you need, having them ready at the right time, and making sure they are all consistent with each other, that is where the process either flows or gets stuck.

FAQs
Can a foreigner register a company in Australia without being there in person?
Yes, the process can be completed remotely. At least one director must be an Australian resident, but shareholders can be based anywhere in the world.
How long does ASIC take to process a company registration?
Usually one to two business days if all documents are in order and the application is submitted correctly the first time.
Do I need a custom constitution or can I use the default rules?
The Replaceable Rules work fine for simple setups. If you have multiple shareholders or any investor arrangements, a custom constitution is worth drafting properly.
What is the difference between an ACN and an ABN?
Your ACN comes from ASIC when your company is registered. Your ABN is a separate tax identifier you apply for through the Australian Business Register after that.
What is a Director ID and is it really required?
Yes, it is mandatory. Every director must get one through the Australian Business Registry Services before being appointed. It is a personal identifier introduced to prevent misuse of director identities in Australian companies.
