Company vs Sole Trader: Which Business Structure is Right for You?
IntuitiveCalc Team
Financial Content Specialist
Choosing between a sole trader and a company is one of the most important decisions you'll make when starting a business in Australia. This choice affects your taxes, liability, compliance costs, and growth potential. This comprehensive guide compares both structures to help you make the right decision.
Quick Decision Guide
Choose Sole Trader if: You're testing a business idea, expect income under $80,000, want minimal paperwork, and don't need liability protection.
Choose Company if: You expect to earn $100,000+, need limited liability, want to access business loans, plan to hire employees, or might seek investment.
Quick Comparison Table
| Factor | Sole Trader | Company (Pty Ltd) |
|---|---|---|
| Setup Cost | $0 (free) | $576 (ASIC fee) |
| Annual Fees | $0 | $310/year (ASIC review fee) |
| Tax Rate | Personal rate (0-45% + Medicare) | Flat 25% |
| Liability | Unlimited personal liability | Limited to company assets |
| Compliance | Minimal (personal tax return) | Company tax return + ASIC annual |
| Accounting Costs | $300-$1,000/year | $1,500-$4,000/year |
| Asset Protection | None - personal assets at risk | Personal assets protected |
| Business Loans | Personal credit checked | Build business credit |
| Investment | Cannot sell equity | Can issue shares to investors |
Tax Comparison: When Does a Company Save Tax?
The biggest difference is tax rates. Sole traders pay personal income tax (up to 45% + 2% Medicare), while companies pay a flat 25% tax rate. However, the comparison isn't always straightforward because company profits need to be extracted somehow.
Tax Comparison at Different Income Levels
| Taxable Income | Sole Trader Tax | Company Tax | Difference |
|---|---|---|---|
| $50,000 | $7,717 | $12,500 | Sole trader saves $4,783 |
| $80,000 | $17,267 | $20,000 | Sole trader saves $2,733 |
| $100,000 | $24,967 | $25,000 | Break-even point |
| $120,000 | $31,667 | $30,000 | Company saves $1,667 |
| $150,000 | $43,267 | $37,500 | Company saves $5,767 |
| $200,000 | $64,667 | $50,000 | Company saves $14,667 |
| $300,000 | $109,667 | $75,000 | Company saves $34,667 |
Note: Company tax shown assumes profits retained in company. Dividends to shareholders incur additional tax.
Important: Extracting Company Profits
Company profits must eventually be extracted as salary (taxed at personal rates) or dividends (franked dividends come with franking credits). The 25% company tax isn't the final tax - it's paid upfront and credited against shareholders' personal tax. The real benefit is deferring tax and having more cash to reinvest in the business.
Liability Protection: The Key Advantage of Companies
The most significant difference between structures is liability protection. This becomes crucial if your business faces lawsuits, debts, or failures.
Sole Trader Liability
- You ARE the business - no legal separation
- Personally liable for ALL business debts
- Personal assets at risk (house, car, savings)
- Creditors can pursue your personal property
- Bankruptcy affects you personally
- No protection if sued by customers
Company Liability
- Company is a separate legal entity
- Directors only liable for company assets
- Personal assets usually protected
- Creditors can only pursue company property
- Company can go insolvent, you don't
- Business debts stay with the company
When Directors Can Be Personally Liable
Company protection isn't absolute. Directors can be personally liable for:
- Insolvent trading - continuing to trade when you know company can't pay debts
- Personal guarantees - most banks require these for business loans
- Tax debts - ATO can pursue directors for unpaid PAYG, super, GST
- Fraud or negligence - personal misconduct as a director
- Phoenix activity - deliberately liquidating to avoid debts

Making Your Decision
The right structure depends on your specific circumstances. Start as a sole trader if you're testing a business idea or expect lower income. Choose a company if you need liability protection, expect high profits, or plan to grow significantly. Remember, you can always convert from sole trader to company later as your business grows.
