Choosing your business structure is one of the first big decisions you’ll make as a founder in Australia. It affects your tax position, personal risk, funding options and how you run the business day to day.
If you’re weighing up sole trader vs company, you’re not alone. Both structures can be great - it just depends on your goals, risk profile and growth plans. In this guide, we’ll break down how each option works in Australia, the practical pros and cons, key tax differences (at a high level), and the setup steps and legal documents you’ll need so you can move forward with confidence.
Let’s dive in.
What’s The Difference Between A Sole Trader And A Company?
Sole Trader (you are the business)
A sole trader is the simplest structure. Legally, there’s no separation between you and the business - you own the assets, earn the income and are personally responsible for the debts and obligations.
You can still hire staff, use a registered business name and claim business expenses. Many founders start here to test an idea or run a lean solo operation.
Company (a separate legal entity)
A company (usually a proprietary limited, or “Pty Ltd”) is a separate legal person. It can own property, enter into contracts, sue and be sued in its own name. Shareholders own the company; directors manage it.
This separation is a key reason businesses incorporate: it can limit your personal liability and often makes it easier to raise capital, bring on co-founders or exit later by selling shares.
Names and public registers
Whichever structure you choose, think about branding and transparency. Trading under your personal name as a sole trader doesn’t require a separate business name, but if you use any other name, you’ll register it and your details appear on the public business names register. With a company, your entity name and officeholder details are recorded with ASIC. If you’re unsure about naming, it helps to clarify the difference between a business name vs company name before you lock it in.
Pros And Cons For Australian Entrepreneurs
Pros of being a sole trader
- Simple and low cost: Minimal setup - get an ABN, and register a business name if you’re not using your personal name. There’s no annual ASIC company review fee (though business names have renewal fees).
- Full control: You make decisions quickly without board or shareholder approvals.
- Straightforward tax filing: Business income is included in your individual tax return (no separate company return).
- Flexible while you test and learn: Ideal for side hustles, freelancers, consultants and early validation.
Cons of being a sole trader
- Unlimited personal liability: If the business can’t pay its debts or a claim is made, your personal assets are exposed. This is a key risk to weigh carefully.
- Growth and funding can be harder: It’s less common to attract investors into a sole trader structure and more complex to bring in co-owners.
- Tax at higher income levels: Profits are taxed at your marginal rates. At scale, this can be higher than the company tax rate.
- Loss offsets have rules: Sole trader losses are subject to Australia’s non‑commercial loss rules, which can limit offsetting those losses against other personal income unless certain tests are met.
- Continuity and exit: There’s no separate entity to sell; you would sell your assets, IP and goodwill, which can be less straightforward than a share sale.
Pros of registering a company
- Limited liability in most cases: The company holds the liability for business debts and obligations. Keep in mind lenders and landlords often ask for personal guarantees, and directors must avoid insolvent trading.
- Attractive for growth: Easier to bring on co-founders, offer equity, raise capital and ultimately sell shares or the business.
- Perception and credibility: “Pty Ltd” can help with enterprise clients, tenders and supplier accounts.
- Continuity: The company continues even if shareholders or directors change, which supports succession planning.
Cons of registering a company
- Higher setup and ongoing costs: You’ll pay incorporation fees and an annual ASIC review fee, plus typically higher accounting and legal costs.
- More administration: Companies must keep proper registers and records and meet ASIC reporting and update obligations.
- Governance responsibilities: Directors owe legal duties and should understand decision‑making requirements and documentation standards.
Tax Considerations In Australia
This is a high‑level overview to help your decision. Sprintlaw is a law firm - we don’t provide tax advice. For tailored tax planning, speak with your accountant.
Sole trader tax
- Business profits are taxed at your individual marginal rate via your personal tax return.
- Losses are subject to non‑commercial loss rules for individuals - you may need to pass certain tests (or obtain the Commissioner’s discretion) before offsetting losses against other personal income.
- You register for GST once your turnover is expected to reach $75,000 (or if you choose to voluntarily register).
Company tax
- The company pays income tax on its profits (commonly 25% for base rate entities, otherwise 30%).
- As a shareholder or employee, you pay personal tax on what you receive (e.g. salary, director fees or dividends). Franking credits may apply to dividends depending on the company’s tax paid.
- Companies can retain profits for reinvestment, which can offer flexibility in cash flow and planning.
Practical tip: If you’re still exploring whether an ABN is right for your situation, it can be helpful to understand the advantages and disadvantages of having an ABN before you move ahead.
How To Choose The Right Structure
There’s no one “best” answer - it’s about what’s best for you now and where you’re headed.
Choose sole trader if you:
- Want to get started quickly with minimal cost and compliance.
- Are testing a concept or offering with low risk and few stakeholders.
- Don’t need outside investment or multiple owners right now.
Choose company if you:
- Plan to scale, raise capital or share ownership with co-founders.
- Operate in a riskier environment (e.g. larger contracts, higher liabilities) and want a separate legal entity.
- Value the credibility and continuity that come with a company structure.
Also consider your industry’s expectations. Some enterprise clients or government panels prefer contracting with companies, which can influence the timing of incorporation.
Setting Up And Staying Compliant
Step-by-step: setting up as a sole trader
- Apply for an ABN: Most businesses need an Australian Business Number before they invoice or register for GST.
- Register your business name (if needed): If you trade under a name other than your personal name, register it. Your business name and holder details are searchable on the public register.
- Set up your banking and accounting: Keep clean, separate records for business income and expenses.
- Check licences and permits: Depending on your industry, you might need local or state approvals.
- Prepare your core contracts and policies: Even as a sole trader, it’s smart to use written customer terms, and if you’ll collect personal information, have a Privacy Policy.
Step-by-step: setting up a company
- Plan ownership and roles: Decide initial share split, directors and how decisions will be made.
- Choose and check your company name: Make sure it’s available and not infringing others’ IP.
- Incorporate with ASIC: Register your company, then obtain an ACN and ABN. If you want help, a fixed‑fee Company Set Up service can make this smoother.
- Appoint directors and issue shares: Ensure you meet Australian officeholder rules, including resident director requirements where applicable.
- Adopt your governance documents: Many companies adopt a Company Constitution and, where there’s more than one owner, a Shareholders Agreement to set ground rules for decision‑making, equity transfers and dispute resolution.
- Open a company bank account and accounting system: Keep company finances separate from personal funds to preserve clean records.
- Register for tax and payroll obligations: Obtain TFN, register for GST (if required) and set up PAYG withholding if you pay staff.
Privacy, data and marketing
In Australia, many small businesses with annual turnover under $3 million aren’t covered by the Privacy Act, but there are important exceptions (for example, health service providers and businesses that trade in personal information). Regardless of the formal threshold, customers expect transparency about data. If you collect personal information (names, emails, payment details), publish a clear Privacy Policy explaining what you collect and why, and secure that data appropriately.
Consumer law and your customers
If you sell goods or services, you’ll need customer‑facing terms that align with the Australian Consumer Law (ACL), covering things like refunds, warranties and fair marketing. Clear terms reduce disputes, set expectations and protect your IP. If your business has a website, it’s common to include online terms and a privacy statement; if you’re service‑based, use a written client agreement.
Employment and contractors
Hiring staff triggers Fair Work obligations, including minimum entitlements, accurate payslips, safe work practices and proper documentation. Put written agreements in place for employees (such as an Employment Contract) and for independent contractors to set scope, pay and IP ownership.
Risk, insurance and guarantees
Good contracts help manage risk, but insurance is also important (e.g. public liability, professional indemnity). If you’re operating through a company, be mindful that lenders and landlords may request director or personal guarantees - understand the implications before you sign.
Ongoing compliance
- Sole traders: Keep accurate records, lodge tax returns and BAS (if registered for GST), and renew your business name on time.
- Companies: Maintain company registers, update ASIC when details change, pay annual review fees and meet director duties (including not trading while insolvent). Document key decisions in board or shareholder resolutions.
Common documents most startups prepare
- Customer Terms or Service Agreement: Sets out deliverables, payment, IP and liability limits to reduce disputes.
- Privacy Policy: Explains how you handle personal information and supports customer trust.
- Employment Contract and key workplace policies: Defines roles, pay, confidentiality and IP ownership for staff.
- Contractor Agreement: Clarifies scope, deliverables and IP when engaging freelancers or suppliers.
- Shareholders Agreement (companies): Covers ownership, decision‑making, exits and dispute mechanisms between founders.
- Company Constitution (companies): Governs internal management, director powers and share processes.
- Non‑Disclosure Agreement (NDA): Protects confidential information during early discussions with partners, suppliers or investors.
Not every business needs every document on day one, but getting the essentials right early can save time and headaches down the track. If you’d like help tailoring these to your model, we’re here to support you.
