Sole Trader, Company or Trust: What’s the Difference for Small Business Owners?
Choosing the right business structure is one of the first and most important decisions a small business owner will make. The structure you choose affects how your business is taxed, how much paperwork you deal with, your level of personal risk, and even how easily you can grow in the future. In Australia, the most commonly used business structures are:
- Sole traders.
- Partnerships.
- Companies.
- Unit trusts.
- Family trusts.
Each structure works differently and has its own advantages and responsibilities. Understanding the differences can help you choose the structure that best suits your business goals.
1. Sole trader
A sole trader is the simplest and most common structure for small businesses. As a sole trader, you operate and control the business yourself, even if you employ staff. The business and the owner are legally the same entity. This means the business income is treated as your personal income for tax purposes.
- Simple and inexpensive to set up.
- Minimal legal and tax formalities.
- Full control over decision-making.
- You keep all profits after tax.
- Straightforward reporting through your personal tax return.
Things to consider.
- You are personally responsible for all business debts.
- Personal assets (such as your home or vehicle) may be at risk if the business cannot pay its debts.
- Access to finance can be more limited.
- Tax is paid at your personal marginal tax rate, which may become higher as profits grow.
- There are fewer tax planning opportunities compared to other structures.
Tax & reporting
Sole traders report business income and expenses in their individual tax return and pay tax at individual tax rates.
2. Partnerships
A partnership is when two or more people or entities operate a business together and share income, responsibilities, and decision-making. Partners run the business together and share profits or losses according to the partnership agreement. The partnership itself does not pay tax, but it must lodge an annual partnership tax return.
- Relatively simple and inexpensive to establish.
- Combines the skills, resources, and capital of multiple people.
- Shared workload and responsibility.
- Flexible profit-sharing arrangements.
Things to consider.
- Each partner is personally liable for the debts of the partnership
- Partners can be responsible for debts incurred by other partners
- Personal disagreements can impact the business
- Partners cannot transfer ownership without agreement from the others
- Income is taxed at each partner’s personal tax rate
Tax & reporting.
The partnership lodges a tax return showing the business income and each partner’s share. Each partner then reports their share in their personal tax return.
3. Companies
A company is a separate legal entity that operates independently of its owners (shareholders). Companies are regulated by the Australian Securities and Investments Commission.
The company earns income, pays expenses, and pays tax in its own name. Directors manage the company, while shareholders own it.
- Limited liability—shareholders are generally not personally responsible for company debts.
- A company can continue even if ownership changes.
- Greater access to finance and investment opportunities.
- A flat company tax rate (currently 25% for eligible small businesses).
- A more professional structure for larger operations.
Things to consider.
- Higher setup and ongoing administrative costs.
- More complex compliance requirements.
- Directors must meet legal obligations.
- Money earned by the company belongs to the company, not the owners personally.
Tax & reporting.
Companies lodge an annual company tax return and pay tax on profits at the company tax rate. Owners can access company profits through wages, director fees, or dividends.
4. Trusts
A trust is a structure where a trustee manages assets or a business for the benefit of beneficiaries. The trustee can be an individual or a company. Two common types used by small businesses are family (discretionary) trusts and unit trusts.
The trustee runs the business and distributes income to beneficiaries. In discretionary trusts, the trustee decides how profits are distributed each year.
- Strong asset protection compared to sole traders and partnerships.
- Flexibility in distributing income to beneficiaries.
- Potential tax planning opportunities.
- Beneficiaries are generally not liable for trust debts.
Things to consider.
- More complex to establish and manage.
- Higher setup and administration costs.
- The trust must operate according to the trust deed.
- Losses cannot be distributed to beneficiaries.
- Undistributed income may be taxed at very high rates.
Tax & reporting.
Most discretionary trusts do not pay tax themselves. Instead, income is distributed to beneficiaries, who pay tax at their own marginal tax rates.
Risk, administration & growth considerations.
When comparing structures, three major factors usually matter most for small business owners.
- Risk & asset protection.
Sole traders and partnerships expose personal assets to business debts. Companies and trusts can provide greater separation between personal and business assets. - Administration & compliance.
Sole traders and partnerships have minimal reporting requirements. Companies and trusts require more documentation, annual returns, and ongoing compliance. - Growth & tax planning.
Companies and trusts often provide more flexibility for tax planning, investment, and expansion. They can also make it easier to bring in partners or investors.
Need help deciding which structure is right for your business?
Many businesses start as sole traders and later transition to a company or trust structure as they grow. However, there is no single “best” structure—it depends on your business goals, risk tolerance, expected profits, and future plans.
