Choosing between a company vs sole trader structure is a critical decision for any Australian business owner. Getting it wrong can cost you in tax, expose your personal assets to risk, and create compliance headaches. This guide provides the clarity you need to choose the right structure from day one.
Key Differences
- Sole Trader: You and the business are legally the same. Simple, low-cost setup, but your personal assets (like your home) are at risk if the business fails. Tax is paid at your personal marginal rate.
- Company (Pty Ltd): A separate legal entity that protects your personal assets through limited liability. Taxed at a flat, lower company rate (currently 25% for eligible businesses), but has higher setup and ongoing compliance costs with ASIC.
- Liability: A company offers significant asset protection, while a sole trader has unlimited personal liability. This is often the primary reason to incorporate.
- Tax: Companies become more tax-effective as profits rise, allowing profits to be retained and reinvested at a lower tax rate. Sole traders are taxed at personal rates up to 47% (including Medicare levy).
- Cost & Admin: Sole traders are cheaper and simpler to set up (a free ABN) and run. Companies require formal registration with ASIC, annual fees, and separate tax returns.
- Best For: Sole trader is ideal for new, low-risk, or small-scale businesses. A company is better for established businesses with significant profit, assets to protect, employees, or plans to seek investment.
Quick Definition: Sole Trader vs Company
Understanding the legal distinction between these two structures is the first step.
A sole trader is the simplest business structure. You and your business are considered a single legal entity. You trade under your own name or a registered business name, using your personal Tax File Number (TFN) to report income via your individual tax return. Your Australian Business Number (ABN) identifies you to the government and other businesses.
A company, specifically a proprietary limited (Pty Ltd) company, is a separate legal entity registered with the Australian Securities and Investments Commission (ASIC). It is owned by shareholders and managed by directors. It has its own TFN, lodges its own tax returns, and can enter into contracts in its own name. This separation is the source of its key benefits and obligations. For more detail, see the distinction between an ABN and an ACN.
Company vs Sole Trader
This table breaks down the essential differences under Australian law.
| Attribute | Sole Trader | Company (Pty Ltd) |
|---|---|---|
| Legal Status | You and the business are one legal entity. | A separate legal entity from its owners (shareholders). |
| Liability | Unlimited. Personal assets are at risk. | Limited. Personal assets are generally protected. |
| Tax Rate | Personal marginal tax rates (0% to 45% + Medicare levy). | Flat company tax rate (currently 25% for base rate entities). |
| Asset Protection | None. Business debts are your personal debts. | High. The “corporate veil” separates business and personal assets. |
| Setup Cost | Low. Free ABN registration via the ABR. | Higher. ASIC registration fees apply. Check current ASIC guidance. |
| Ongoing Admin | Low. Report income on your personal tax return. | High. Requires annual ASIC review, separate tax returns, and formal record-keeping. |
| Raising Capital | Difficult. Limited to personal finance and loans. | Easier. Can issue shares to investors. |
| Control | Full control over all decisions and assets. | Control is defined by the company constitution and shareholder agreements. |
Tax Treatment: How the ATO Views Each Structure
Tax is a major factor when deciding if a company vs sole trader which is better for your bottom line. The Australian Taxation Office (ATO) treats each structure very differently.
As a sole trader, all business profit is considered your personal income. You report it in your individual tax return and pay tax at your personal marginal rates, which can reach 47% (including the Medicare levy). This simplicity is appealing at first, but can become tax-inefficient as your income grows.
A company pays tax on its profits at a flat rate. For a base rate entity (turnover under $50 million), this is currently 25%. This allows the business to retain and reinvest post-tax profits far more effectively than a sole trader could. Money is only taxed again at personal rates when paid out to shareholders as dividends. Always check current ATO guidance for the latest tax rates.
GST, PAYG and Superannuation Rules
Your day-to-day tax obligations also vary.
- GST: The rules are the same for both. You must register for Goods and Services Tax (GST) once your annual turnover reaches or is expected to reach $75,000.
- PAYG Instalments: Both structures will likely be required by the ATO to pay income tax in instalments throughout the year once a certain profit threshold is met.
- Superannuation: As a sole trader, you are not an employee, so you must make your own contributions to your super fund. For a company, if you work in the business as a director, the company must pay Superannuation Guarantee contributions on your salary, just like any other employee.
Liability and Asset Protection: The Corporate Veil
One of the most significant reasons business owners choose a company structure is for asset protection.
As a sole trader, there is no legal separation between you and your business. This means you have unlimited personal liability. If your business incurs debts it cannot pay, creditors can legally pursue your personal assets including your family home, car, and savings to settle the debt.
A proprietary limited (Pty Ltd) company provides a legal shield known as the “corporate veil”. Because the company is a separate legal entity, it is responsible for its own debts. This gives you limited liability, meaning your personal assets are generally safe from business creditors. This protection holds as long as you have met your director’s duties and have not provided personal guarantees for business loans. This is a crucial benefit explained in our guide on how asset protection strategies work in practice.
Setup and Ongoing Costs
The costs involved are a practical consideration.
A sole trader setup is extremely low-cost. Registering for an ABN on the Australian Business Register (ABR) is free. Ongoing costs are minimal, mainly consisting of accounting fees for your personal tax return.
Setting up a company is more expensive. You must pay a registration fee to ASIC. Check current ASIC guidance for the latest fees. Ongoing costs include an annual ASIC review fee to keep the company registered, plus higher accounting fees for lodging a separate company tax return and maintaining compliance records.
Compliance and Admin Burden
A sole trader has a low administrative burden. Your primary obligations are to keep records of income and expenses and report them on your personal tax return.
A company has a significantly higher compliance burden. As a director, you have legal responsibilities under the Corporations Act 2001. This includes:
- Lodging an annual company tax return with the ATO.
- Paying an annual review fee to ASIC.
- Keeping detailed financial records.
- Notifying ASIC of any changes to company details (e.g., address, directors).
- Ensuring the company does not trade while insolvent.
If you hire staff, both structures must meet employer obligations under the Fair Work Ombudsman.
When a Sole Trader Is Better
The sole trader structure is the logical choice for many new Australian businesses. It is often the best fit if you are:
- Just starting out or testing a business idea. The low setup cost and minimal admin are perfect for ventures with low initial revenue.
- A freelancer, contractor, or consultant in a low-risk industry.
- Running a small side hustle or a business where your personal asset exposure is minimal.
When a Company Is Better
A company structure becomes the smarter choice as your business grows and its risk profile changes. You should incorporate if you:
- Need to protect personal assets. This is the number one reason. Limited liability is non-negotiable for businesses taking on debt, hiring staff, or operating in higher-risk sectors.
- Are earning significant profits. Once your income pushes you into higher tax brackets, the 25% company tax rate becomes more effective for retaining capital.
- Plan to hire employees. A company structure formalises obligations and can help protect you from vicarious liability.
- Want to raise capital or bring on partners. Investors and lenders view a company as a more credible and stable entity.
- Need to boost professional credibility with larger corporate clients who may have policies against engaging sole traders.
Worked Example: Comparing Tax Outcomes in Australia
Let’s compare the tax outcomes for a business making a $150,000 net profit in a financial year.
As a Sole Trader: The entire $150,000 profit is added to the owner’s personal taxable income.
- Using 2024-25 individual tax rates, the tax payable (including Medicare levy) would be approximately $42,000.
- This leaves $108,000 in post-tax cash for the owner.
As a Company: The business can manage how profits are distributed.
- The company pays the director a salary of $70,000. The personal tax on this (including Medicare levy) is approx. $14,300.
- The remaining company profit is $80,000 ($150k – $70k).
- The company pays tax on this at 25%, which is $20,000.
- Total Tax Paid: $14,300 (personal) + $20,000 (company) = $34,300.
- This is a tax saving of $7,700 compared to the sole trader structure. The company also retains $60,000 in post-tax profit for reinvestment.
Note: This is a simplified example. Seek professional advice. Check current ATO tax rates.
How to Switch From Sole Trader to Company
Switching is a common step for a growing business. Follow this process carefully.
- Seek Professional Advice: Before you begin, consult an accountant. They will help you navigate critical tax implications like Capital Gains Tax (CGT) when transferring business assets to the new company.
- Register the Company: Choose a name and register your proprietary limited (Pty Ltd) company with ASIC. This formally creates the new legal entity. Our guide on how to set up a company in Australia can help.
- Apply for a New ABN and TFN: Your new company needs its own ABN and TFN. You will apply for these after the company is registered.
- Open a Company Bank Account: All business income and expenses must now go through a dedicated bank account in the company’s name.
- Transfer Assets and Contracts: Formally transfer any business assets, client contracts, and supplier agreements from your name to the company’s name.
- Cancel Your Sole Trader ABN: Once you are fully operating through the company, you should cancel your old sole trader ABN to avoid confusion with the ATO.

Frequently Asked Questions
Is a company always better than a sole trader?
No. For new businesses, freelancers, or ventures with low revenue and risk, a sole trader is often the best choice due to its simplicity and low cost. A company becomes “better” when asset protection and tax planning become priorities.
Do companies pay less tax than sole traders in Australia?
Often, yes, especially at higher profit levels. Companies pay a flat 25% tax rate (for base rate entities), while sole traders pay personal income tax rates up to 47%. This allows companies to retain and reinvest profits more effectively.
Can I change from sole trader to company later?
Yes, this is a very common pathway for successful businesses in Australia. The process requires registering a new company with ASIC and transferring your business operations across, but it’s crucial to get tax advice first to manage any CGT implications.
What structure is best for contractors or tradies?
While many start as sole traders for simplicity, a company structure is often recommended for tradies and contractors. It provides vital protection for personal assets (like the family home) from worksite liability or business debts.
Does a company protect personal assets?
Yes, this is one of its primary benefits. A company provides limited liability, which creates a legal separation between business debts and your personal assets. This protection is valid as long as you meet your director’s duties.
What is the main difference between a sole trader and a company?
The key difference is legal status. A sole trader and their business are a single legal entity with unlimited personal liability. A company is a separate legal entity, offering its owners limited liability and asset protection.
How much does it cost to set up a company vs a sole trader?
Setting up as a sole trader is free (ABN registration). Setting up a company involves an ASIC registration fee, which you can check on the ASIC website. Check current ASIC guidance for the latest fees.
Do I need an ABN as a sole trader or company?
Yes, both structures need an Australian Business Number (ABN) to operate in Australia. A company will also have an Australian Company Number (ACN) issued by ASIC upon registration.
Deciding on the right business structure is a foundational step with long-term consequences. To ensure your choice aligns with your financial goals and protects your assets, expert advice is essential.
