Starting a company in Australia is a structured, multi-step process, not just an ASIC form.
From validating your idea and choosing the right structure to appointing directors, registering with ASIC, setting up tax accounts, banking, and compliance systems, successful incorporation requires getting the order and details right from day one. -
A Pty Ltd company offers limited liability and scalability, but comes with higher compliance.
Companies suit businesses planning to grow, hire, raise capital, or formalise operations, but they also require ongoing ASIC reviews, director duties, proper record-keeping, and tax reporting that must be actively managed. -
Most incorporation problems come from early decisions, not later growth.
Choosing the wrong structure, skipping Director ID requirements, unclear ownership splits, mixing finances, or missing tax registrations are the most common (and costly) mistakes founders make when registering a business in Australia.
Starting a business is exciting but figuring out how to start a company in Australia can quickly become confusing when legal requirements, government registrations, and compliance obligations come into play.
In this guide, we’ll cover the key steps involved, including
- Deciding whether a company structure is right for you
- Choosing directors and shareholders
- Registering with ASIC
- Understanding what needs to be done immediately after setup
By the end, you’ll have a clear understanding of the company registration process and the confidence to set up your business correctly from day one, without unnecessary delays or compliance risks.
Before you incorporate, write down who actually controls the company; not just who owns shares. Decisions around director roles, voting power, share splits, and who can sign contracts often get rushed at registration, then become painful to change later. Even for single-founder companies, thinking this through early makes future investor onboarding, banking approvals, and compliance far smoother.
10 steps to start and register a company in Australia
Before we dive in, here’s a simple roadmap on how to start a company in Australia in ten practical steps, from testing your idea to getting fully registered and ready to trade.
Step 1: Do your market research before you start a company in Australia
Before you worry about ASIC forms or tax registrations, sense-check that there’s actually a business worth incorporating.
Focus on three things:
- Customer and problem: Who are your ideal customers? What specific problem are you solving for them? How urgent or painful is it?
- Competition: Who else is solving the same problem? How are they pricing, positioning, and delivering their product or service? What will make your offer meaningfully different?
- Demand and pricing: Is there enough demand at a price point that covers your costs and leaves margin after tax, software, staff, and compliance costs?
Your goal here isn’t a perfect forecast, it’s to avoid spending time and money figuring out how to start a company in Australia for an idea that doesn’t have a clear market.
Step 2: Write a simple business plan before incorporating a company in Australia
Once you’re confident there’s a real opportunity, capture the basics in a short, practical plan. This doesn’t have to be a formal document; 1–2 pages is enough.
At minimum, cover:
- Business model: What are you selling, to whom, and how will you make money (one-off sales, retainers, subscriptions, etc.)?
- Go-to-market: How will you reach customers, online, referrals, partners, marketplaces, physical locations?
- Costs and resources: What will it cost to get started (tools, people, licences, marketing) and to keep running month to month?
- Funding and runway: Are you self-funding, using savings, getting a loan, or bringing in investors? How long can you run before you need consistent revenue?
- Growth and structure implications: If things go well, will you hire, bring in co-founders, or raise capital? This helps decide when a company structure makes sense.
With this groundwork done, you’re in a much stronger position to move into the next step: deciding whether a company structure is right for your business.
Step 3: Decide if a company structure is the right way to register a business in Australia
Before registering anything, it’s important to confirm whether a company is the right structure for your business. In Australia, you can operate as a sole trader, partnership, trust, or company, each with different legal, tax, and compliance implications.
A company is usually the right fit when you want to separate the business from the individual. Once registered, a company exists as its own legal entity with its own property, rights, and obligations (separate from owners/directors).
In Australia, most small businesses choose a company set up as a proprietary company limited by shares (Pty Ltd) because it supports growth while limiting member liability.
But a company also comes with more compliance than other structures (e.g., ASIC annual reviews/record-keeping and director responsibilities), so it’s worth choosing deliberately.
Structure | Separate legal entity | Personal liability | How tax generally works | Admin & compliance load | Best for |
Sole trader | No | Highest | Income taxed at individual rates | Low | Testing an idea, simple operations |
Partnership | No (partners personally involved) | High (can be shared, but still personal) | Partners taxed individually on their share | Medium | Two founders starting small |
Trust | Usually yes (via trustee), but depends on setup | Varies (often via corporate trustee) | Tax outcomes depend on trust distributions; losses generally stay in the trust | Medium–High | Asset protection / family wealth planning |
Company (Pty Ltd) | Yes | Limited (typically to unpaid share amounts) | Company pays company tax: 30% unless eligible for 25% as a “base rate entity” | High | Scaling, hiring, raising funds, credibility |
If you’re unsure, it’s worth getting advice early. Choosing the wrong structure can lead to unnecessary tax, compliance issues, or costly changes later, especially once your business starts generating revenue.

Step 4: Choose and check your company name before registering in Australia
Once you’ve decided on a company structure, the next step is choosing a company name. Your company name is the legal name registered with ASIC and must be unique and compliant with Australian naming rules.
Before applying, make sure your chosen name:
- Is available on the ASIC register
- Is not misleading, offensive, or restricted without approval
- Uses the correct legal ending (e.g. Pty Ltd)
If you plan to trade under a different name, you’ll also need to register a business name separately. Alternatively, you can register your company using its ACN as the name and add a business name later.
Once your company name is confirmed, you can move on to setting up your directors, shareholders, and ownership structure.

Step 5: Set your company directors, shareholders and share structure
Before you can register your company with ASIC, you must decide on the key people and how ownership will be divided. These are formal legal requirements under Australian company law and must be ready when you lodge your application.
Category | Minimum requirements | Notes |
Directors | At least 1 director for a proprietary company | Must ordinarily reside in Australia; must have a Director ID before appointment. |
Director ID | Every director must have a Director Identification Number | This is a unique 15-digit ID you apply for via ABRS before becoming a director. |
Shareholders (members) | At least 1 shareholder | The same person can be both director and shareholder. |
Share structure | At least one class of shares must be issued | Details of issued shares and members are required on the company’s register. |
Company secretary | Optional for proprietary companies | Only required for public companies. |
What you need to decide
- Who will be the director(s)?
Each director must be at least 18 years old and cannot be disqualified under the Corporations Act. - Director ID compliance:
Every director must apply for a Director ID before they can be appointed to the company. - Who will be the shareholder(s)?
A shareholder (or member) owns part of the company through shares. This can be a person or another company. - Share structure:
Decide how many shares you will issue and how ownership will be divided. This affects control, voting rights, and profit entitlements. You must record this in your own share register and tell ASIC about it.
Document ownership and founder rules in a shareholders’ agreement
Once you’ve decided who the directors and shareholders are, it’s worth putting the ownership and founder rules in writing, even if it’s a small, closely held company.
A shareholders’ agreement (or founders’ agreement) can help clarify:
- Decision-making: How big decisions are made (for example, by board resolution or unanimous shareholder approval).
- Roles and responsibilities: Who is expected to handle which areas of the business (operations, finance, sales, product, etc.).
- Equity and vesting: How shares are allocated, and what happens if a founder leaves early.
- Exit and share transfers: What happens if someone wants to sell their shares, bring in a new investor, or exit the business.
- Disputes: How disagreements will be resolved without paralysing the company.
This kind of document doesn’t replace the company constitution or the Corporations Act, but it sits alongside them and reduces misunderstandings between founders as the business grows.
You don’t have to cover every scenario on day one, but agreeing on the basics early usually saves cost and friction later.
Step 6: Register your company with ASIC (How to incorporate a company)
Once your structure, name, directors, shareholders, and share setup are decided, you’re ready to register the company with the Australian Securities and Investments Commission (ASIC). This is the step that officially creates your company as a legal entity.
You can register online directly with ASIC or through a registered agent. You’ll need to provide:
- Proposed company name (or use the ACN as the name)
- Registered office address in Australia (not a PO Box)
- Principal place of business
- Director details, including Director ID
- Shareholder details and their shareholdings
- Share structure (number and class of shares)
- Whether you’ll use replaceable rules or a company constitution
Once ASIC approves the application, you’ll receive:
- An Australian Company Number (ACN)
- A Certificate of Registration
From that point, the company is live and must meet ongoing ASIC obligations, including keeping details up to date and paying the annual review fee.
The ten steps in this guide aren’t just administrative, they follow the natural lifecycle of a business. Early steps focus on commercial viability (market research, planning, structure choice), middle steps establish the legal entity (ASIC registration, directors, shareholders, tax accounts), and later steps ensure the company can actually operate and scale (banking, systems, licences, insurance, and compliance).
Founders who rush straight to incorporation without working through these stages often end up redoing registrations, restructuring ownership, or fixing tax and compliance issues later. Treating company setup as a staged process, not a one-off task, significantly reduces friction as the business grows.
Step 7: Set up your company tax and business registrations in Australia
After your company is registered with ASIC, you’ll need to complete the key tax and business registrations so it can legally operate.
For most Australian companies, this usually includes:
Registration | When do you need it |
All companies carrying on an enterprise in Australia need an ABN. | |
TFN (Tax File Number): company | Every company needs its own TFN for income tax and other ATO obligations. |
If projected GST turnover is $75,000 or more (or $150,000+ for non-profits), or you opt in voluntarily. | |
If you have employees, pay company directors, or withhold from certain contractors/others without an ABN | |
If you trade under a name different from the company’s exact legal name (e.g. “Bright Labs” instead of “Bright Labs Pty Ltd”). |
Most of these can be lodged in one go using the Business Registration Service after you have your ACN.
Step 8: Understand your ongoing company and ASIC compliance obligations
Once you’ve worked through how to start a company in Australia and completed the setup steps, your focus shifts to staying compliant. Incorporation isn’t a one-off task, there are ongoing legal and tax obligations you need to manage.
These obligations apply whether you register a business directly as a company from day one or move into a company structure later.
Core ongoing obligations for Australian companies
Area | What you must do |
ASIC annual review | Pay the annual review fee, confirm company details, and pass a yearly solvency resolution. |
Keep details up to date | Notify ASIC when directors, addresses, share structure, or company details change. |
Maintain company registers | Keep accurate records of directors, shareholders, shares issued, and key decisions (e.g. resolutions, minutes). |
Financial records | Maintain financial records that correctly explain the company’s transactions and financial position. |
Tax and reporting | Lodge company income tax returns, BAS/IAS where required, and meet PAYG and super obligations if you have employees. |
Director duties | Directors must act in the company’s best interests, avoid improper use of their position, and ensure the company can meet its debts. |
Getting these basics right is just as important as the setup itself. When you have decent systems in place, good bookkeeping, regular check-ins, and clear records; it’s much easier to run the company day to day and avoid nasty compliance surprises later.
Step 9: Open a company bank account and set up your records
Once you’ve worked through how to start a company in Australia and completed your registrations, the next step is to get your financial and operational systems in place.
Open a dedicated company bank account
Set up a separate bank account in the company’s name. This helps you:
- Keep company money completely separate from personal funds
- Make it easier to track income and expenses
- Show clear records if the ATO or a lender ever reviews your books
Most banks will ask for your ACN, ABN, company details, and ID for officeholders.

Set up your accounting and record-keeping
From day one, put basic systems in place to track money and decisions, such as:
- Cloud accounting software to send invoices, track expenses, and reconcile bank transactions
- A simple chart of accounts tailored to how your business earns and spends
- Secure storage for key company records: director and shareholder registers, minutes, resolutions, contracts, and tax records
Good systems early on save you time, reduce compliance risk, and make it easier to work with your accountant.
Step 10: Check licences, insurance and operational readiness before you start trading
Before you start trading, it’s important to make sure your company is actually ready to operate, not just registered on paper.
Licences and permits
Depending on your industry and location, you may need specific licences, permits, or registrations. Examples include:
- Food business registrations
- Building or trade licences
- Professional registrations or accreditations
- Local council permits (for signage, outdoor seating, or certain retail activities)
A quick check with your state or territory business regulator and local council can help confirm what applies to you.
Insurance
Consider whether your company needs:
- Public liability insurance: to help protect against claims arising from injury or property damage linked to your business activities
- Professional indemnity insurance: if you provide advice or professional services
- Product liability insurance: if you manufacture or sell products
- Workers compensation: if you employ staff (this is mandatory under state and territory laws)
The right mix will depend on what your company does and its risk profile, so it’s worth getting tailored advice.
Operational readiness
Finally, sense-check whether you’re operationally ready to go live. For example:
- Do you have terms and conditions or client contracts in place?
- Are your payment methods, invoicing, and refunds set up and clear?
- Do you have basic privacy and data handling practices if you collect customer information?
Working through these points helps ensure that once all the registrations are done, your company can start trading smoothly and with fewer surprises.
What are the common mistakes when you start a company in Australia?
When you’re focused on how to start a company in Australia, it’s easy to miss small details that turn into big headaches later. Here are some of the most common mistakes new founders make:
- Choosing a company structure too early (or for the wrong reasons)
Locking into a company when a simple sole trader setup would do or vice versa can lead to unnecessary cost, admin, or later restructuring. - Not getting a Director ID before appointment
Every director needs a valid Director ID before they’re appointed. Skipping this step can delay your ASIC registration. - Leaving ownership and founder rules vague
Not having a basic shareholders’ or founders’ agreement can cause friction later around roles, equity, exits, or bringing in new investors. - Mixing personal and company finances
Using personal bank accounts for company income and expenses makes record-keeping messy and can weaken the separation between you and the company. - Missing key tax registrations or starting them too late
Forgetting to register for GST, PAYG withholding, or a company TFN when required can lead to penalties or cash flow issues. - Treating compliance as a one-off task
Ignoring ASIC annual reviews, not updating company details, or skipping proper records and minutes makes it harder to stay compliant and raise capital later.
Many founders underestimate how easy it is to make compliance mistakes when starting a company in Australia. Missing Director ID requirements, registering under the wrong name or structure, forgetting tax registrations, or failing to separate personal and company finances can trigger penalties, delays, or forced restructuring.
Professional support helps ensure the company is set up correctly the first time; aligning structure, tax, ownership, and compliance so your business can trade confidently without avoidable legal or financial setbacks.

Frequently Asked Questions
Can I start as a sole trader and incorporate a company in Australia later?
Yes. Many Australian founders start as sole traders and then incorporate a company later once they have revenue, partners, or higher risk.
When you switch from sole trader to company:
- The company becomes a separate legal entity, with its own ABN, TFN, bank account, and obligations.
- You may need to transfer assets, contracts, and licences into the company’s name (for example, leases, supplier agreements, or IP ownership).
- The company will pay company tax on its profits, and you’ll pay personal tax on any salary or dividends you receive.
- You may also need to cancel or update your sole trader ABN if that structure is no longer used.
Because there can be tax and legal consequences to “moving” a business into a company, it’s worth planning the timing with an accountant so you don’t accidentally trigger avoidable CGT or stamp duty.
What tax issues should I consider before deciding to incorporate a company?
Deciding how to start a company in Australia isn’t just legal, it’s a tax decision too. Some of the key tax issues to think about are:
- Tax rate differences: A company generally pays tax at the corporate tax rate, while you pay personal tax on salary and dividends. For some profit levels, a company can be more tax-efficient; for others, it may not be.
- Retaining profits in the company: Companies can retain profits to reinvest in the business, but pulling money out for personal use has rules (salary, dividends, loans) and tax consequences.
- Division 7A and shareholder loans: If you take money out of the company other than through proper salary or dividends, it can trigger complex rules (like Division 7A deemed dividends) if not handled correctly.
- GST and PAYG obligations: Incorporating doesn’t remove GST, PAYG withholding or super obligations, you may actually add more registrations and reporting.
- Losses and timing: How existing or future business losses are treated can differ between a sole trader and a company structure.
Because these are highly situation-dependent, it’s best to speak with a tax adviser or accountant before you incorporate, especially if you expect high profits, multiple shareholders, or rapid growth.
How long does it take to incorporate a company in Australia once I’m ready?
If you have all details ready (name, directors, shareholders, addresses, share structure), online ASIC registration is usually the same day, often within minutes. Delays mostly come from missing Director IDs, unclear ownership splits, or a company name that doesn’t pass ASIC checks.
