Whenever you see a successful business, someone once made a courageous decision. – Peter F. Drucker
Starting a business is one of the most rewarding steps you can take. But before you order business cards or register your business name, you need to make a crucial choice: what structure will you use?
Your ownership in business – or how your business is legally set up – determines how you’ll be taxed, how much personal liability you’ll carry, and even how easy it is to grow or sell your business. In Australia, there are four main business ownership structures: sole trader, partnership, company, and trust. Each has unique advantages and trade-offs.
In this article, we’ll explain each structure in plain English, compare the pros and cons, and outline keytax considerations so you can make an informed choice.
What is the Definition of Business Ownership?
Business ownership refers to the way a business is legally recognised in Australia. It answers important questions:
Who controls the business?
Who is responsible for debts and liabilities?
How are profits distributed and taxed?
It’s important to see the Business as a separate asset. This Business is owned and operated through different structures.
In simple terms, ownership is about the balance between complexity and risk. If you want total control and simplicity and risk is not an issue, a sole trader structure might suit. If you want tighter risk management with limited liability and easier access to finance, a company may be the way to go.
Choosing the right structure ensures your business isn’t just compliant with the ATO and ASIC – it’s also set up to protect your assets and support your goals.
The 4 Types of Business Ownership (Australia)
1. Sole Trader
A sole trader is the simplest form of business ownership. You own the business and are legally responsible personally therefore hold all the risk . It’s common for tradespeople, consultants, and freelancers.
Pros:
Quick and inexpensive to set up (just an ABN required).
You have full control of decisions and profits.
Less paperwork and fewer compliance obligations.
Cons:
Unlimited liability – you’re personally responsible for all debts and claims arising from the business activity.
Profits are taxed at your personal marginal tax rate, which can be higher than the company tax rate.
Limited opportunities for growth or raising outside capital.
2. Partnership
A partnership is when two or more people run a business together. Common among family businesses, small practices, or friends starting a venture.
Pros:
Easy and inexpensive to set up (partnership agreement strongly recommended).
Shared workload, skills, and resources.
Lower risk than a Sole trader as risk can be shared with the partner.
Each partner pays tax on their share of the profit at their personal rates, allowing for a small amount of income splitting.
Cons:
Joint liability – each partner is still personally responsible for the debts of the business.
Disagreements can damage both the business and personal relationships.
Partners pay tax at individual rates, which may be less efficient as profits grow.
3. Company
A company is a separate legal entity from its owners (shareholders). Think of a company as a separate person. Although it may be “Your Company” it is not you!!!! In Australia, most small and medium-sized businesses use a proprietary limited (Pty Ltd) company structure.
Pros:
Limited liability – personal assets are generally protected.
Taxed at the company rate (currently 25% for base rate entities), often lower than individual rates.
Easier to raise finance and attract investors.
Greater credibility and professional image.
Cons:
More expensive and complex to set up (ASIC registration required).
Ongoing compliance obligations: company tax returns, annual statements, director responsibilities.
Directors can still be personally liable in some situations (e.g., insolvent trading, unpaid taxes and employee entitlements).
4. Trust
A trust is an arrangement where a trustee runs the business on behalf of beneficiaries. Nobody legally owns a Trust, it is a separate legal entity. Commonly used for family businesses, investments, or asset protection strategies.
Pros:
Flexibility to distribute income among beneficiaries, which may reduce overall tax.
Asset protection – business assets are held in the trust, not in your personal name.
Can be useful for succession planning.
Cons:
Complex and costly to establish (requires a trust deed and professional advice).
Strict legal and compliance obligations.
Undistributed income is taxed at the top marginal tax rate.
Losses cannot be distributed to beneficiaries but are kept in the trust and offset against future gains (Negative gearing in a trust is not generally recommended)

Business Ownership & Tax Considerations When Going into Business
Your choice of business ownership directly impacts your tax obligations. Here’s a simplified view of how the ATO treats each structure:
Sole trader: You report income and expenses on your individual tax return and pay tax at personal marginal rates. You need to register for GST if turnover exceeds $75,000. Superannuation contributions are voluntary.
Partnership: The partnership lodges an annual tax return, but each partner reports their share of income and expenses on their personal tax return. No separate tax is paid by the partnership itself.
Company: A company is a separate taxpayer and pays tax at the company rate (25% or 30%). Directors must ensure GST, PAYG withholding, and superannuation obligations are met. Profits can be retained or distributed as dividends.
Trust: A trust generally distributes income to beneficiaries, who pay tax at their personal rates. If income isn’t distributed, the trust is taxed at the highest individual rate.
Other key considerations:
Registering for an ABN and business name.
GST registration if turnover exceeds $75,000.
PAYG withholding if employing staff.
Superannuation guarantee obligations for employees.
The right structure can minimise tax, but the wrong one can cost you significantly in the long run. This is where advice from accountants (like Bishop Collins) makes all the difference.
