People underestimate how much a small error during registration can cost them later. A mismatched name, a missed document, a wrong structure choice, and suddenly you are dealing with ASIC rejections, ATO compliance gaps, or a forced restructure six months in.
Company set up in Australia is genuinely straightforward when done right. The problem is that most mistakes happen not because people are careless, but because nobody told them what to watch out for. This guide does exactly that.
Mistake 1: Choosing the Wrong Business Structure
This is the most expensive mistake, and it happens right at the start. Your structure affects:
- How much tax you pay
- Whether your personal assets are at risk
- How easy it is to bring in investors or partners later
- What compliance obligations you carry ongoing
A lot of people register as a sole trader thinking it is simpler, without realising they carry full personal liability for every business debt. Others jump to a Pty Ltd without understanding what comes with it.
Changing your structure after the fact is possible but painful. It costs money, takes time, and can trigger unexpected tax consequences. Before you register anything, be honest about where your business is going, not just where it is today.
Mistake 2: Not Getting a Director ID Before You Apply
This one catches people off guard because it is a newer requirement that is not well publicised. Here is what you need to know:
- Every director must have a Director Identification Number before being appointed
- It is issued through the Australian Business Registry Services
- It is free to apply for but processing is not always instant
- If you submit your registration without it, the process stalls immediately
Apply for your Director ID well before your planned registration date. Not the day before. Not the same morning. Do it early.
Mistake 3: Inconsistent Details Across Documents
This is the most common reason ASIC sends applications back. Small things create big delays:
- A middle name included on your passport but left out on Form 201
- An address formatted differently across two different forms
- A company name that does not exactly match across all documents
Go through every document side by side before you submit. Every name, every address, every detail needs to be identical across all of them. It takes an extra thirty minutes and saves weeks.
Mistake 4: Using a P.O. Box as Your Registered Office
Your registered office must be a real, physical address in Australia. A P.O. box does not qualify. Full stop.
What does qualify:
- Your own business premises
- A lawyer or accountant’s office address
- A compliant virtual office that meets ASIC standards
The address needs to be accessible during standard business hours for official government and legal correspondence. Confirm it is compliant before you list it. Finding out it does not qualify after submission is an avoidable problem.
Mistake 5: Confusing a Company Name With a Business Name
These are two completely different things. Mixing them up causes real problems.
- Company name: The legal name of your entity registered with ASIC, for example, “Smith Holdings Pty Ltd”
- Business name: The name you trade under publicly if it differs from your company name, for example, “Sydney Fresh Supplies”
If you want to operate under a name that is different from your registered company name, you need to separately register that trading name with ASIC. Assuming your company name automatically covers your brand name is a mistake that can lead to fines or a forced rebrand if that name is already taken.
Mistake 6: Skipping the Company Constitution
A lot of people doing a company set up in Australia for the first time see the constitution as optional and move on. Technically you can rely on the Corporations Act’s Replaceable Rules. For a solo founder with a simple setup, that is probably fine.
But if any of these apply to you, a custom constitution is not optional:
- You have co-founders or business partners
- You are planning to bring in investors
- You have multiple shareholders with different arrangements
- You want clarity on what happens if someone exits
Without it, disagreements that could have been resolved in two sentences become expensive legal disputes. Draft it before you register, not six months later when tensions are already running high.
Mistake 7: Not Collecting Signed Consents Before Submitting
Before lodging your registration with ASIC you need signed written consent from:
- Every director being appointed
- Every secretary if you are appointing one
- Every initial shareholder
These need to be in place at the time of registration, not collected after. When directors and shareholders are in different countries and time zones, chasing signatures at the last minute becomes a genuine problem. Build in time for this step. It is predictable and completely avoidable with a bit of planning.
Mistake 8: Treating Tax Registrations as an Afterthought
ASIC registration is step one. The moment you receive your Australian Company Number, three more things need to happen immediately:
- Tax File Number (TFN): Apply through the ATO right away. Needed to lodge returns and interact with the government on any financial matter
- Australian Business Number (ABN): Required to invoice clients legally and claim GST credits. Apply through the Australian Business Register using your new ACN
- GST Registration: Mandatory if annual turnover will exceed AUD 75,000. Can be done voluntarily below that threshold
Without an ABN you cannot legally invoice anyone. Without a TFN you cannot lodge tax returns. Do not wait until your first invoice is already overdue to sort this out.
Mistake 9: Not Thinking Through Your Share Structure
How you set up shares at incorporation matters more than most first-time founders realise. Get this wrong and you create problems around:
- How profits are distributed between shareholders
- What happens when someone wants to exit
- How you structure future investment rounds
- Voting rights and decision-making control
Most straightforward setups start with 100 ordinary shares at $1 each. But if your business involves partners or planned investment, get proper advice on this before you register. Restructuring shares after the fact is technically doable but rarely pleasant.
Mistake 10: Going Quiet on Compliance After Registration
Registration is not the finish line. A lot of businesses get set up correctly and then let post-registration obligations slide. Here is what you are required to keep on top of:
- Notify ASIC within 28 days of any changes to directors, shareholders, or company address
- Pay the annual ASIC review fee to keep the company active
- Lodge tax returns and Business Activity Statements on schedule with the ATO
- Keep your company registers updated and accurate
Missing these deadlines leads to penalties and in serious cases, deregistration. Set up a simple compliance calendar the day your company is registered. It takes almost no effort to maintain and saves significant stress down the road.
Do Your Company Set Up in Australia the Right Way
Most of the mistakes on this list are entirely avoidable. They do not happen because people are not paying attention. They happen because the process has more layers than it appears and the cost of fixing errors after registration is almost always higher than doing it right the first time.

FAQs
What happens if I submit incorrect information to ASIC during registration?
ASIC will reject or return the application for correction. Fixing errors after submission involves additional forms, fees, and delays that are easy to avoid upfront.
Can I change my business structure after registering?
Yes, but it involves a full new registration and can trigger tax and legal consequences. Getting the structure right from day one is always the better move.
Do I need a lawyer to register a company in Australia?
Not legally, but it is worth it for anything beyond a simple single-director company, especially if a custom constitution or shareholder agreements are involved.
How soon after ASIC registration should I apply for an ABN?
Immediately. Without an ABN you cannot legally invoice clients, and there is no good reason to delay it even by a day.
What is the difference between a company name and a business name in Australia?
Your company name is your legal registered entity with ASIC. A business name is a separate trading name you register if you operate publicly under a different brand. You need both if they differ.
