Starting a business in Australia means choosing the right structure. This structure protects owners from personal financial risk and follows strict ASIC regulations. This guide explains what a proprietary limited company is, how it works and how to register one.
A quick guide to proprietary limited company
A proprietary limited company (Pty Ltd) is a separate legal entity that protects owners from personal liability. It has private ownership, meaning shares are not available to the public. A Pty Ltd company must follow ASIC regulations, appoint at least one director and meet tax and reporting obligations. This structure suits businesses needing limited liability and a professional image.
What is a proprietary limited company and how does it work?
A proprietary limited (Pty Ltd) company is a type of company registered in Australia. It is a separate legal entity, meaning it exists independently from its owners. This structure protects shareholders from personal liability, as they are liable for the amount they invest in the company, not its total debts.
Pty Ltd companies are private, meaning their shares are not available to the public. They cannot be listed on the Australian Stock Exchange (ASX). This structure is ideal for small to medium-sized businesses that want limited liability and a clear business framework.
How a Pty Ltd company differs from other business structures
A Pty Ltd company is different from sole traders and partnerships in key ways:
- Sole traders own and run their business alone. They are personally liable for the debts of the company.
- Partnerships involve two or more people sharing profits, losses and liabilities.
- Public companies can sell shares to the public and must follow stricter regulations.
Key features of a proprietary limited company
A Pty Ltd company has several important features:
✔ Private ownership – Shares are not available to the public.
✔ Limited liability – Shareholders are liable for the amount they invest.
✔ Legal status – A separate legal entity from its owners.
✔ Compliance obligations – Must follow the Corporations Act 2001.
Corporate structure of a Pty Ltd company
The roles within a Pty Ltd company are clearly defined:
| Role | Responsibilities |
|---|---|
| Director | Manages company operations and ensures compliance. |
| Shareholder | Owns shares and receives dividends. |
| Secretary | Handles regulatory filings and record-keeping. |
A company must have at least one director and one shareholder. These roles help ensure the business meets legal requirements and operates effectively.
Is a pty ltd company the right type of company for you?
Choosing the right type of company is key to running a successful business. A proprietary limited company offers limited liability and a structured legal framework, but it may not suit every business. Below is a comparison of business structures to help you decide.
Comparing business structures
Each business structure has different risks and benefits.
| Structure | Key features | Risks |
|---|---|---|
| Sole trader | Simple to set up and manage | Personally liable for the debts of the business |
| Partnership | Shared control and profits | Partners are liable for the amount of all business debts |
| Pty Ltd company | Limited liability for shareholders and a separate legal entity | More compliance and reporting requirements |
| Public company | Can sell shares to the public and raise funds | Public companies are required to follow strict laws and regulations |
A proprietary limited company suits businesses that want limited liability and structured management. Unlike sole traders, Pty Ltd companies keep personal and business assets separate. They also offer more credibility when dealing with regulators and shareholders.
Benefits of choosing a Pty Ltd company
A Pty Ltd company offers several advantages:
✔ Personal asset protection – Members are liable only for their investment.
✔ Professional business image – A company name must include ‘Pty Ltd’ to show it is a separate legal entity.
✔ Tax benefits – A lower corporate tax rate may apply compared to sole traders.
When to consider switching to a different structure
You may need to change your company structure if:
- Your business needs more than 50 non-employee shareholders or wants to raise capital from the public.
- You plan to list on the Australian Stock Exchange (ASX).
- You want to transfer shares easily between owners.
A Pty Ltd company suits many businesses but may not be the best choice for every situation. Consider your business name, structure and long-term goals before deciding.

How proprietary limited companies differ from other business structures
Different business structures offer varying levels of control, liability and compliance. A proprietary limited company provides a balance of limited liability and private ownership, but it is not the only option. Understanding these differences helps business owners choose the right structure.
Comparison of business structures
The table below highlights the key differences between proprietary limited companies, public companies, sole traders and partnerships.
| Feature | Pty Ltd | Public company | Sole trader | Partnership |
|---|---|---|---|---|
| Ownership | Private (up to 50 non-employee shareholders) | Public (unlimited shareholders) | Single owner | Multiple owners |
| Liability | Limited to share value | Limited to share value | Unlimited liability | Shared liability |
| Compliance | Moderate | High | Low | Moderate |
| Capital raising | Private funding | Shares to the public | Personal funds | Combined funds |
Legal and compliance differences
Proprietary limited companies follow different rules from public companies under the Corporations Act 2001.
- Shareholder limits – A Pty Ltd company is limited to 50 non-employee shareholders, while public companies can have unlimited shareholders.
- Regulatory requirements – Public companies are required to disclose more financial details and follow stricter rules.
- Capital raising – Public companies can sell shares to the public and list on the Australian Stock Exchange (ASX). Proprietary companies must rely on private investment.
- Compliance – Public companies submit a wide range of reports, while Pty Ltd companies have limited disclosure obligations.
A Pty Ltd company suits businesses that want limited liability with lower compliance costs. A public company works best for businesses needing large-scale investment.
How to register a company in Australia: Step-by-step guide
Registering a proprietary limited (Pty Ltd) company in Australia requires meeting legal and administrative steps. The process involves choosing a company name, appointing directors, and submitting documents to ASIC. Below is a step-by-step guide to help you through the process.
Step 1: Choose a company name
Your company name must be unique and follow ASIC rules. It cannot be identical to an existing business name or contain restricted words or phrases. The name must include ‘Pty Ltd’ to show it is a proprietary limited company.
Step 2: Select officeholders and shareholders
A company must have at least one company director and one shareholder. The director must be over 18 and reside in Australia. Shareholders can be individuals or another company.
Step 3: Determine the share structure
A Pty Ltd company is limited by shares, meaning members of the company hold share capital. You must decide:
- The total number of shares
- The value of each share
- The rights attached to shares
Step 4: Prepare key legal documents
A proprietary limited company needs legal documents, including:
- A constitution outlining company rules
- A shareholder agreement to define share rights and responsibilities
Step 5: Register through ASIC
To register a company, submit an application to ASIC with:
- Company details and Australian company number (ACN)
- Details of directors and shareholders
- The registration fee
Step 6: Get an ABN, TFN and GST registration
Once the business is registered, apply for:
- Australian Business Number (ABN) – Required for trading
- Tax File Number (TFN) – Needed for tax purposes
- Goods and Services Tax (GST) registration – If turnover exceeds $75,000
Completing these steps helps ensure your Pty Ltd company meets legal requirements.
Choosing a company name: What you need to know
Your company name is an important decision. It must follow ASIC rules, reflect your brand and be available for registration. A strong name helps customers recognise your business and builds trust.
ASIC guidelines for company names
ASIC sets rules for naming a proprietary limited company. Your company name must:
- Be unique and not identical to an existing business name or company name.
- Include ‘Pty Ltd’ to show it is a proprietary limited company.
- Avoid misleading words that suggest government approval or illegal activities.
- Exclude restricted terms unless you have special approval (e.g. "bank" or "university").
Use ASIC’s online tool to check if your company name is available before applying.
Branding and domain name availability
A good company name should support branding and online visibility. Before registering, check if the matching domain name is available. A strong online presence helps customers find your business.
Common mistakes to avoid
Avoid these errors when choosing a company name:
❌ Choosing a name too similar to an existing business
❌ Ignoring ASIC restrictions on certain words
❌ Failing to check domain availability
❌ Picking a name that is hard to spell or pronounce
The legal requirements when registering a proprietary limited company
When you register a proprietary limited company in Australia, you must meet certain legal requirements. These obligations ensure that your company operates within the law and remains compliant with Australian business regulations.
ASIC obligations
After registering your Pty Ltd company, you must follow the rules set by ASIC. Some key obligations include:
- Company constitution and governance – A company constitution outlines how your company will be run. It covers decision-making processes, the rights of shareholders, and the responsibilities of directors.
- Annual financial reporting – Your company must submit annual reports to ASIC. These reports include financial statements that show your business’s financial health.
- Director’s duties and responsibilities – Directors must act in the best interests of the company. They must also follow legal duties set out in the Corporations Act 2001, including avoiding conflicts of interest and maintaining accurate company records.
Taxation obligations
Your Pty Ltd company must also meet several taxation obligations:
- Corporate tax rate – The corporate tax rate for small businesses is generally lower than the standard rate. Small businesses with an annual turnover of less than $50 million can benefit from a lower rate.
- BAS, PAYG, and Superannuation compliance – If your company employs staff, you must comply with the BAS (Business Activity Statement) requirements, pay PAYG (Pay As You Go) tax instalments, and contribute to superannuation for employees.
To assist with understanding your tax obligations as a proprietary limited company, it is recommended that you seek support from an accountant.
The importance of legal documentation
To meet these legal and taxation obligations, having the right legal documentation is essential. Some examples include your company constitution, shareholder agreement, and employment agreements.
