One of the first and most important decisions every new business owner faces is choosing a business structure. This choice affects how much tax you pay, your personal liability, and even how easy it is to raise money.
ProfessionalBusiness Advisory Services make this process simple. Instead of guessing, you’ll know exactly which structure works best for your goals.
In this guide, we’ll cover the main options for a business structure in Sydney, compare sole trader vs company in Sydney, and explain the differences in a trust vs company structure.
Why Your Business Structure Matters
Your structure shapes how your business operates. It determines:
- How profits are taxed
- Your level of personal liability
- Record-keeping requirements
- Access to funding and investors
- How easy it is to expand or change later
Making the right decision from the beginning will save you time, money, and stress in the long run.

Main Business Structures in Sydney
1. Sole Trader
A sole trader operates as an individual with full ownership and control. There is no legal separation between you and the business.
Pros:
Quick and inexpensive setup, minimal ongoing administration, full operational control, and access to the 50% Capital Gains Tax (CGT) discount on assets held longer than 12 months.
Cons:
Unlimited personal liability—your personal assets (such as your home or savings) can be used to settle business debts or legal claims. Profits are taxed at individual marginal tax rates (up to 45% plus Medicare levy).
Best for:
Low-risk freelancers, consultants, and micro-businesses starting out.
2. Partnership
A partnership allows two or more people or entities to run a business and share income or losses according to a partnership agreement.
Pros:
Shared startup costs and workload, combined expertise, and simpler administration than a registered company.
Cons:
Partners share joint liability. You can be held personal liable for debts incurred by another partner on behalf of the business.
Best for:
Two or more co-founders running low-to-medium-risk businesses with a formal partnership agreement in place.
3. Company
A Proprietary Limited (Pty Ltd) company is a separate legal entity distinct from its directors and shareholders.
Pros:
Limited personal liability (protects personal assets), a flat 25% corporate tax rate for small base-rate entities (annual turnover under $50M), and greater credibility with banks, suppliers, and investors.
Cons:
Higher initial setup costs, annual ASIC renewal fees ($329+ per year), strict reporting standards, and no 50% CGT discount.
Best for:
Growing businesses, companies taking on commercial contracts/loans, or founders planning to hire staff and raise capital.
4. Trust
A trust structure holds business assets or operations on behalf of beneficiaries. It is managed by a trustee, which can be an individual or a corporate entity.
Pros:
Excellent tax flexibility through profit distributions to beneficiaries in lower tax brackets, strong asset protection when using a corporate trustee, and access to CGT discounts.
Cons:
Complex to establish, higher ongoing accounting fees, and strict Australian Taxation Office (ATO) compliance requirements.
Best for:
Family-owned businesses or entrepreneurs seeking asset protection and structured profit distribution.
Factors to Consider When Choosing
When deciding on a business structure in Sydney, consider:
- Risk Profile: If your industry involves high legal exposure, commercial leases, or debt, a Company or Trust structure provides personal liability protection that a Sole Trader structure cannot.
- Tax Rates vs. Compliance Costs: While a 25% company tax rate sounds attractive compared to individual marginal rates, account for additional ASIC fees, software costs, and company tax returns before switching.
- Scaling & Future Restructuring: You can start as a sole trader and transition into a company as revenue grows. However, restructuring later can trigger CGT or stamp duty considerations if not planned correctly.
Changing Structures Over Time
The good news is you’re not locked in forever. Many businesses start as sole traders and later transition to a company or trust as they grow. The key is to review your situation regularly and adjust when it makes sense.
