Sole Trader vs Company in Australia: Which Structure Is Right for You?

Choosing between operating as a sole trader vs company in Australia is one of the first decisions freelancers and small business owners face – and it’s one that affects your tax bill, your legal exposure, and how much paperwork you deal with every year. There’s no universally correct answer. The right structure depends on your income level, your risk tolerance, and your plans for the business. This guide breaks down both options so you can make an informed choice.

Sole Trader Structure – Pros and Cons

A sole trader is the simplest business structure in Australia. You and the business are legally the same entity – no separate registration beyond an ABN, no separate tax return, and minimal ongoing compliance.

Pros:

• Simple setup – All you need is an ABN from the Australian Business Register, which you can get online in minutes. No registration fees and no ASIC involvement.
• Full control – Every decision is yours. No board resolutions or shareholder agreements.
• Minimal compliance – One personal tax return with a business schedule, plus a BAS if GST-registered. That’s it.
• Easy to close – Cancel your ABN and report your final income. No winding-up process.
• Lower running costs – No ASIC review fee, no separate company tax return, and generally lower accounting fees.

Cons:

• Unlimited personal liability – If your business incurs debts or gets sued, your personal assets are on the line. There’s no legal separation between you and the business.
• Taxed at individual marginal rates – Business income is taxed at your marginal rate, which can be significantly higher than the company tax rate at higher income levels.
• Harder to raise capital – No mechanism to issue shares or equity, so investors generally won’t fund a sole trader.
• No separation between you and the business – Some clients and government tenders prefer dealing with companies.

For many freelancers starting out, the sole trader structure is the obvious choice. The question is whether it stays the right choice as your income grows.

Company Structure – Pros and Cons

A company (typically a proprietary limited company, or Pty Ltd) is a separate legal entity with its own ABN, tax file number, and legal obligations. You can be the sole director and shareholder, but the company is still distinct from you personally.

Pros:

• Limited liability – The company’s debts are generally the company’s problem, not yours. Your personal assets are protected (with some exceptions – directors can be held personally liable for unpaid employee super and PAYG withholding).
• Flat 25% tax rate – Base rate entities pay 25% company tax, compared to individual marginal rates that reach 45% plus Medicare levy.
• Easier to bring in investors or partners – You can issue shares and create shareholder agreements without restructuring the business.
• Perceived credibility – Larger organisations and government bodies often prefer contracting with companies.

Cons:

• Higher setup costs – Registration costs around $500+, plus ongoing ASIC annual review fees (currently $310 for a proprietary company). You may need legal advice on your constitution.
• Annual compliance requirements – Separate company tax return, higher record-keeping standards, and an annual ASIC review.
• Director obligations – Legal duties under the Corporations Act, including preventing insolvent trading. You also need a Director ID.
• Separate tax return – The company lodges its own return, and you lodge a personal return for salary or dividends. Two returns instead of one.
• Can’t withdraw profits freely – Profits come out as director’s salary (subject to PAYG) or dividends (with their own tax treatment). Getting this wrong creates tax problems.

Tax Rate Comparison – Sole Trader vs Company Australia

This is where the sole trader vs company Australia decision often comes down to numbers.

Individual marginal tax rates (2025-26):

Plus the 2% Medicare levy on most taxpayers.

Company tax rate: 25% flat for base rate entities (companies with aggregated turnover under $50 million and no more than 80% passive income).

At first glance, the breakeven point appears to be around $120,000 in taxable income – that’s where the individual marginal rate jumps to 37%, comfortably above the 25% company rate.

But there’s a catch. Company tax isn’t the end of the story. When you take money out of the company as dividends, you pay personal tax on those dividends (with a franking credit for the company tax already paid). The combined effective tax rate – company tax plus personal tax on dividends – means the total tax paid is often similar to what a sole trader would pay.

The real advantage of a company structure emerges when you don’t need to withdraw all the profits. If you can leave money in the company and reinvest it – buying equipment, building up a cash reserve, funding growth – that money is taxed at 25% instead of your higher marginal rate. For sole traders, all business profit is taxed in the year it’s earned regardless of whether you spend it.

Compliance and Reporting Requirements

The compliance gap between the two structures is one of the most underestimated costs.

Sole trader: Personal tax return with business schedule, BAS if GST-registered, keep records for five years. No ASIC obligations, no director ID. Accounting fees typically $500-$1,500.

Company: Separate company tax return, PAYG withholding for director’s salary, annual ASIC review and fee, financial statements, director ID, BAS if GST-registered, plus your personal tax return for salary and dividends. Accounting fees typically $2,000-$5,000+.

For a freelancer earning a modest income, the extra compliance cost of a company can eat into any tax savings. Model this with your accountant before making the switch.

When It Makes Sense to Switch from Sole Trader to Company

Not everyone needs a company, and there’s no magic income number that makes it automatic. However, several signals suggest it might be time to consider the switch:

• Income consistently over $120,000 – If your taxable business income is regularly above $120,000 and you don’t need to withdraw all of it, the 25% company rate starts creating meaningful tax deferral.
• You need liability protection – If your work carries professional risk – consulting, construction, IT services where a mistake could lead to a claim – limited liability provides a genuine safeguard (though you should still carry professional indemnity insurance).
• You’re planning to bring on partners or investors – A company structure makes it straightforward to issue shares and formalise ownership arrangements.
• You want to retain profits in the business – If you’re building up capital for equipment, hiring, or expansion, the lower company rate means more money stays in the business.

One critical point: restructuring from a sole trader to a company can trigger capital gains tax (CGT) on business assets. The ATO has rollover relief provisions in some cases, but you need professional advice before making the move. Don’t just register a company and start invoicing through it – the transition needs to be handled correctly.

Track Your Expenses Either Way

Whether you operate as a sole trader or a company, organised expense records are the foundation of accurate tax reporting. The structure changes how your income is taxed, but the need to track every business expense stays the same.

As a sole trader, your expenses reduce your personal taxable income directly. In a company, expenses reduce the company’s taxable profit. Either way, every legitimate expense you miss is money you’re overpaying in tax.

Taxr works for both structures. You can customise expense categories to match your tax return – whether that’s a sole trader business schedule or a company tax return. Scan receipts as they come in, and the AI extracts the vendor, date, amount, and GST automatically. No manual data entry, no shoebox of paper receipts.

If you’re still getting started with expense tracking, our guide on how to track business expenses as a sole trader covers the fundamentals. And if you’re GST-registered under either structure, our GST receipt tracking guide explains how to stay BAS-ready year-round.

Choose the Right Structure – Then Keep Your Records Sorted

The sole trader vs company decision matters, but it’s not permanent. Many freelancers start as sole traders and transition to a company when the numbers justify it. The important thing is to decide deliberately rather than by default.

Whichever structure you choose, clean financial records from day one make everything easier – tax lodgement, BAS preparation, and any future restructuring. Download Taxr and start tracking your expenses properly.
