Choosing between operating as a sole trader or registering a company is the most consequential early decision you will make as an Australian business owner. It affects how much tax you pay, how much of your personal wealth is at risk, how you can bring in partners or investors, and how much administration you take on every year.
Neither structure is universally better. The right choice depends entirely on your income level, risk exposure, growth plans, and appetite for administrative complexity.

The Fundamental Difference
Sole Trader
A sole trader is you operating a business in your own name.
There is no legal separation between you and the business.
You own all the assets, you are responsible for all the debts, and all business income flows directly to you as personal income.
Company (Pty Ltd)
A company (Pty Ltd) is a separate legal entity that you create and control.
The company can:
- Enter contracts
- Own assets
- Employ staff
- Incur debts
entirely in its own name.
As a director, you run the company.
As a shareholder, you own it.
But the company and you are legally distinct.
This legal separation or lack of it drives almost every practical difference between the two structures.
Liability: What's at Stake
This is usually the primary reason to incorporate.
Sole Trader Liability
You are personally liable for every debt and legal obligation your business incurs.
If your business is sued and loses, the judgment can be enforced against your personal assets, including:
- Your home
- Savings
- Vehicle
- Investments
There is no firewall between your business and your personal life.
Company Liability
Your personal liability is generally limited to your investment in the company (the value of your shares).
If the company is sued or cannot pay its debts, creditors can pursue the company's assets but not yours personally.
Important Exceptions
Limited liability does not protect you if you have:
- Provided personal guarantees on company debts (common for leases, loans, and supplier credit)
- Traded while the company was insolvent (a breach of director's duties)
- Engaged in fraudulent conduct
Despite these exceptions, a company provides significantly stronger personal asset protection than a sole trader structure for most business risks.
Practical Implication
If you work in a low-risk service business with:
- No employees
- No leases
- Minimal contracts
sole trader liability may be acceptable.
If you have:
- Employees
- Physical premises
- Significant client contracts
- Inventory or stock
incorporation is worth considering.
Tax: How Each Structure Is Taxed
Sole Trader Tax
All business income is treated as your personal income and taxed at your marginal rate.
2024–25 Personal Tax Rates
- Up to $18,200: 0% (tax-free threshold)
- $18,201–$45,000: 19%
- $45,001–$120,000: 32.5%
- $120,001–$180,000: 37%
- Over $180,000: 45%
(Plus 2% Medicare Levy applies on income above $26,000.)
A sole trader earning $150,000 in business profit pays tax on the full $150,000 at their marginal rate — resulting in an effective rate of around 38%.
Company Tax
Companies pay a flat tax rate.
For 2024–25:
- Most small companies (base rate entities with turnover under $50 million) pay 25%
- Larger companies pay 30%
A company earning $150,000 pays:
- 25% company tax = $37,500
The remaining $112,500 stays in the company and can be reinvested.
When you eventually pay yourself a dividend from the company, it is offset by franking credits, preventing double taxation.
The Tax Crossover Point
As a rule of thumb, company tax rates become more efficient once business profits consistently exceed approximately $80,000–$100,000.
Below this threshold, sole trader simplicity often outweighs the marginal tax benefit of a company.
Sole Trader Tax Advantages
- Access to the 50% capital gains tax (CGT) discount on business assets held over 12 months (companies do not get this discount)
- Simpler tax compliance one personal tax return
- Lower accounting costs
Company Tax Advantages
- Lower flat rate (25%) compared to top marginal rates (up to 47% including Medicare Levy)
- Ability to retain profits in the company at the company rate, rather than drawing all income personally
- More flexible income splitting arrangements (with proper tax advice)
- Superannuation contributions as a director are a deductible business expense
Setup Costs and Ongoing Compliance
| Sole Trader | Company (Pty Ltd) | |
|---|---|---|
| Setup cost | Free (ABN) | $576 (ASIC registration) |
| Business name | $42–$98 (optional) | $42–$98 (if trading under different name) |
| Annual ASIC fee | None | ~$329/year |
| Tax return | Personal return only | Separate company tax return + personal return |
| Accounting costs | Lower | Higher (company returns are more complex) |
| Director obligations | None | Must maintain ASIC records, lodge annual review, sign solvency resolutions |
| Superannuation | Optional for yourself | Mandatory on director salary |
The ongoing compliance burden of a company is meaningfully higher than a sole trader.
Expect to pay $1,000–$3,000 more per year in accounting fees for a company, depending on complexity.
Banking and Credibility
Both structures can open business bank accounts, but banks generally view companies as more established and creditworthy.
For sole traders:
- Business loans and credit facilities are assessed against your personal financial position.
For companies:
- The company's financial position is assessed separately.
From a client credibility perspective, operating as a Pty Ltd can signal a more established business to:
- Corporate clients
- Government agencies
- Larger organisations
that prefer dealing with companies rather than individuals.
Hiring Employees
Both sole traders and companies can employ staff.
As a Sole Trader
You are personally responsible for all employment obligations, including:
- Wages
- Superannuation
- Leave entitlements
- Workers' compensation
If an employment dispute arises, it is against you personally.
As a Company
Employment obligations sit with the company.
The legal separation provides some buffer against personal liability in employment disputes, though directors can still be personally liable in certain circumstances, particularly for unpaid wages and entitlements.
When to Choose Sole Trader
Sole trader is the right starting point when:
- You are testing a business idea before committing to corporate structure and costs
- Your annual profit is expected to be under $80,000
- You work in a low-risk service business with minimal liability exposure
- You have no employees, no significant contracts, and no commercial premises
- You want minimal administration and accounting costs
- You are a freelancer, consultant, or tradesperson operating independently
When to Choose Company
Company structure is the better choice when:
- Your annual profit exceeds or is approaching $80,000–$100,000
- You want personal asset protection from business liabilities
- You have employees, commercial leases, or significant contracts
- You want to bring in business partners, co-founders, or investors
- You plan to sell the business or seek external funding in future
- Your clients (particularly corporate or government clients) prefer contracting with companies
- You want to retain profits in the business for reinvestment at the lower company tax rate
Can You Switch Later?
Yes.
Many businesses start as sole traders and incorporate into a Pty Ltd as they grow.
This is a standard transition and your accountant can advise on the most tax-efficient way to restructure.
Key Points When Switching
- Your existing ABN as a sole trader does not transfer to the new company — the company receives its own ABN
- Contracts, leases, and supplier accounts in your personal name need to be novated or transferred to the company
- Your bank account, insurance, and government registrations need to be updated
- There may be CGT implications on transferring business assets to a company — specialist advice is essential
Business Address Requirements for Each Structure
Sole Trader
You need a physical address for:
- Your ABN
- Any business name registration
This does not need to meet the same strict requirements as a company registered office, but it is published on public registers.
Company (Pty Ltd)
You are legally required to have a registered office address:
- A physical street address in Australia
- Accessible during business hours
- Capable of receiving legal documents
A PO box is not acceptable.
Using a Virtual Address
In both cases, using a virtual address from Space Penguin means your home address never appears on the ASIC public register.
A virtual address satisfies:
- The company registered office requirement
- The sole trader business address requirement
simultaneously, from $20/month.
Frequently Asked Questions
At what income level does a company become more tax-efficient than a sole trader?
Generally when business profits consistently exceed $80,000–$100,000, the company tax rate of 25% produces meaningful tax savings compared to personal marginal rates.
However, the total benefit depends on whether you draw all profits as a salary (which is taxed personally anyway) or retain some in the company.
Discuss your specific circumstances with your accountant.
Can a sole trader have employees?
Yes.
Sole traders can employ staff.
Your personal liability extends to all employment obligations.
What is a base rate entity?
A base rate entity is a company with:
- Aggregated turnover under $50 million
- No more than 80% of assessable income derived from passive income (interest, dividends, royalties, rent)
Most small operating companies in Australia qualify and pay 25% company tax.
Is a trust better than a sole trader or company?
Trusts offer flexibility for:
- Income distribution
- Asset protection
but are more complex and expensive to establish and maintain.
They are commonly used by family businesses and higher-income individuals.
Consult a specialist accountant or lawyer before establishing a trust structure.
Do I need a company to get a business loan?
No.
Sole traders can access business loans, but they are typically assessed against your personal financial position.
Banks generally view companies as having separate borrowing capacity, though they will often still require director guarantees for small company loans.
Whether you're a sole trader or a company, Space Penguin virtual addresses keep your home address private and your business ASIC-compliant from $20/month.
