Choosing the wrong business structure can cost you thousands in tax or worse, expose your personal assets to business risks. If you’re deciding between a sole trader, trust, or company in Australia, this guide breaks down the pros and cons in plain English, helping you make the right choice.
Getting this structure right from day one is critical for asset protection, tax minimisation, and future growth.
Sole Trader vs Trust vs Company
In Australia, a sole trader is the simplest structure with minimal costs but no asset protection, a trust offers flexible income distribution and strong asset protection, and a company provides limited liability with a fixed tax rate. The best business structure in Australia for a small business depends on your income, risk level, and growth plans.
- Sole Trader: Best for low-risk, small businesses where simplicity is key.
- Trust: Best for tax planning, asset protection, and family businesses.
- Company: Best for high-growth businesses aiming to scale or raise capital.
What Is a Sole Trader?
A sole trader is the simplest business structure in Australia. When you operate as a sole trader, you and your business are legally the same entity. It’s operated by one individual using their personal Australian Business Number (ABN).
This simplicity is its biggest drawcard, making it a popular choice for freelancers, contractors, and new small business owners.
Sole Trader Advantages and Disadvantages
Pros:
- Easy & Cheap Setup: Registering an ABN on the Australian Business Register (ABR) is fast and free.
- Low Costs: Minimal ongoing compliance costs and simple tax reporting on your personal tax return.
- Full Control: You have complete control over business decisions.
Cons:
- Unlimited Personal Liability: This is the critical flaw. Your personal assets (home, car, savings) are at risk if the business incurs debt or faces legal action. There is no asset protection.
- Limited Tax Planning: Business income is your personal income, taxed at individual marginal rates, offering little flexibility.
- Perceived as Less Professional: Can be harder to secure large contracts or financing compared to a company.

What Is a Company?
A proprietary limited (Pty Ltd) company is a separate legal entity from its owners (shareholders) and managers (directors). This legal separation is its most powerful feature, creating a financial firewall known as limited liability.
Company Structure Australia Advantages and Disadvantages
Pros:
- Limited Liability: Protects your personal assets from business debts. Your risk is generally limited to the value of your shares.
- Fixed Tax Rate: A company pays tax at a fixed corporate rate (currently 25% for base rate entities) on its profits, which is often lower than top individual tax rates.
- Scalability: It’s easier to raise capital, bring in investors, and transfer ownership.
Cons:
- Higher Costs & Compliance: Setting up with the Australian Securities and Investments Commission (ASIC) and annual reviews involve fees.
- Complex Administration: Directors have legal duties, and the business must lodge a separate company tax return and maintain statutory records.
- Trapped Profits: Getting money out of the company can be complex (e.g., via wages or dividends), which have tax implications.
This structure is the clear choice for founders who want to scale up or build the strongest possible wall around their personal assets. For a step-by-step guide, see our article on how to register a company with ASIC.
What Is a Trust?
A trust is a legal arrangement where a person or a company (the trustee) holds and manages assets for the benefit of others (the beneficiaries). The most common type for businesses is a discretionary trust, often called a family trust.
This structure is a powerful tool for asset protection and tax planning, making it a go-to for family businesses and investors.
Trust Structure Australia Benefits and Drawbacks
Pros:
- Strong Asset Protection: When set up correctly (e.g., with a corporate trustee), assets held in the trust are protected from the personal creditors of the beneficiaries.
- Tax Flexibility: The trustee can distribute income to beneficiaries (e.g., family members on lower tax brackets) each year to minimise the overall family tax bill.
- 50% CGT Discount: Can access the Capital Gains Tax (CGT) discount on eligible assets held for more than 12 months, which a company cannot.
Cons:
- Complexity and Cost: Requires a formal legal trust deed to set up, and administration is more involved than for a sole trader.
- Cannot Retain Profits: Income must be distributed each year. Any profit left in the trust is taxed at the highest marginal rate, making it inefficient for reinvesting profits.
- Losses are Trapped: Business losses cannot be distributed to beneficiaries and are trapped within the trust.

This table provides a snapshot comparison of the pros and cons for sole trader, trust, and company structures to help guide your decision.
| Feature | Sole Trader | Company | Discretionary Trust |

Tax Comparison: Sole Trader vs Company vs Trust Tax Australia
Understanding the tax rates for a sole trader vs company vs trust is crucial. Your choice directly impacts how much of your profit you keep.
- Sole Trader: All business profit is your personal income and is taxed at individual marginal tax rates (from 0% up to 45% plus Medicare levy). Simple, but can become expensive as your income grows.
- Company: Profits are taxed at the fixed corporate tax rate (currently 25% for base rate entities). This is ideal for retaining profits to reinvest in business growth. When profits are paid out to shareholders as dividends, they may come with franking credits to prevent double taxation.
- Trust: The trust itself generally pays no tax. Instead, income is distributed to beneficiaries, who then pay tax at their individual marginal rates. This allows for strategic income splitting to family members on lower tax brackets, reducing the total tax paid.
Warning: A trust cannot retain income efficiently. Any undistributed profit is taxed at the highest marginal rate (47%), making it a poor choice for reinvesting profits.
Asset Protection Comparison
Your exposure to personal risk is a major factor in the sole trader vs trust vs company debate.
- Sole Trader: Offers no asset protection. Your personal assets (home, savings) and business assets are one and the same. If the business fails, creditors can pursue your personal wealth.
- Company: Provides high asset protection through limited liability. The company is a separate legal entity, so business debts are its responsibility, not yours personally. Directors can still be liable for breaches of duties or personal guarantees.
- Trust: Delivers high asset protection. Because the assets are legally owned by the trust (via the trustee), they are generally shielded from creditors of the beneficiaries. Using a corporate trustee provides an additional layer of protection.
Setup Costs & Compliance
The initial and ongoing costs vary significantly between structures. You need to balance the one-off setup expense against the annual compliance burden.
| Requirement | Sole Trader | Company (Pty Ltd) | Discretionary Trust |
|---|---|---|---|
| Setup Registration | ABR for ABN (free) | ASIC registration | Legal drafting of Trust Deed |
| Approx. Setup Cost | $0 | $576 (ASIC fee) + professional fees | $800 – $2,500+ for a quality deed |
| Annual Fees | Minimal (just your accountant) | $343 ASIC Annual Review Fee (for 2026) | Varies (e.g., ASIC fee if corporate trustee) |
| Tax Return | Individual Tax Return | Company Tax Return | Trust Tax Return + Beneficiary Statements |
| Compliance Body | ATO | ASIC and ATO | ATO |
Fees are indicative for 2026 and subject to change. Always check the current ATO business structures guide and ASIC company registration fees.
Step-by-Step: How to Choose the Right Structure
- Define Your Business Goals: Is this a side hustle, a full-time career, or an empire you plan to sell?
- Estimate Your Income and Growth: If you expect high profits or plan to reinvest heavily, a company structure is often more tax-effective.
- Assess Your Risk Exposure: Are you in a high-liability industry like construction or consulting? If so, asset protection is non-negotiable. A company or trust is essential.
- Consider Your Personal Tax Position: Do you have a spouse or family members on lower incomes? A trust allows you to legally split income and reduce your overall tax.
- Factor in Costs and Admin: Are you prepared for the higher setup and annual compliance costs of a company or trust? If not, a sole trader may be a better starting point.
- Seek Professional Advice: This is the most important step. An accountant can model the financial outcomes of each structure for your specific situation.
Worked Example: Freelance Consultant Earning $180,000
Let’s compare a freelance consultant projecting $180,000 in net profit.
- Sole Trader: The entire $180,000 is added to their personal income. After deductions, they would pay tax at high marginal rates. There is no asset protection.
- Company: The company pays tax at 25% on the $180,000 profit ($45,000 tax). The remaining $135,000 can be retained for growth or paid out as a salary/dividend, attracting further personal tax. This structure is great for reinvesting profits.
- Trust: The consultant could distribute the $180,000 profit. For example, $90,000 to themselves and $90,000 to their spouse who has no other income. This splits the income across two individuals, potentially resulting in a much lower overall tax bill for the family compared to the sole trader option.
In this scenario, for pure tax efficiency on distributions, the trust is likely the best option. For reinvesting profits to grow the business, the company is superior. The sole trader structure is the least tax-effective at this income level.
Common Mistakes When Choosing a Business Structure
- Mistake #1: Starting a High-Risk Business as a Sole Trader.
- Fix: If your business has any significant financial or legal risk, establish a company or trust from day one for asset protection.
- Mistake #2: Setting Up a Trust and Ignoring Compliance.
- Fix: Ensure you conduct annual trustee resolutions to distribute income and keep meticulous records. Failure to do so can have severe tax consequences.
- Mistake #3: Choosing a Structure for Tax Reasons Only.
- Fix: Consider the long-term strategy. A company might save tax now, but getting profits out can be costly later. A trust offers distribution flexibility but can’t retain profits. Align the structure with your goals for growth, asset protection, and eventual exit.
- Mistake #4: Not Reviewing Your Structure as the Business Grows.
- Fix: What works today may not work in three years. Review your structure annually with your accountant, especially when your income, risk, or business goals change.
Frequently Asked Questions (FAQs)
Which business structure is best in Australia for a small business?
There is no single “best” structure. For simplicity and low cost, a sole trader is best. For asset protection and growth, a company is superior. For tax flexibility and family businesses, a trust is often ideal. The best small business structure depends on your specific circumstances.
Is a company better than a sole trader in Australia?
A company is better than a sole trader if you need asset protection, plan to grow significantly, want to raise capital, or wish to reinvest profits tax-effectively. For a simple, low-risk venture, the cost and complexity of a company may not be justified.
Are trusts tax-free in Australia?
No. This is a common myth. A trust must distribute its income to beneficiaries, who then pay tax on it at their individual marginal rates. If a trust fails to distribute its income, that profit is taxed at the highest possible rate (47%).
Can I change my business structure later?
Yes, you can change from a sole trader to a company or trust. However, this is a complex process and can trigger Capital Gains Tax (CGT) and other transfer duties. It is crucial to get professional advice before making the change to manage the tax implications.
What is the cheapest business structure to set up?
The sole trader is by far the cheapest and simplest structure to set up in Australia. All you need is an ABN, which is free to register.
What business structure is best for asset protection?
Both companies and trusts offer strong asset protection compared to a sole trader. A discretionary trust with a corporate trustee is often considered the gold standard for protecting business and personal assets from creditors.
