Sole Trader vs. Company: Which Business Structure Is Right for You?

One of the first decisions you’ll make when starting a business in Australia is how to structure it. The two most common options are operating as a sole trader or setting up a company (Pty Ltd). Each has distinct advantages, and the right choice depends on your circumstances.

Operating as a sole trader

A sole trader is the simplest business structure. There’s no legal separation between you and the business — you are the business. Setting up is straightforward: you register an ABN, and you’re ready to go.

The advantages are real. Setup costs are minimal. You have complete control over every decision. Your tax return is simpler because your business income is reported on your personal return. You can draw money from the business whenever you like without the formalities a company structure requires.

But there are trade-offs. As a sole trader, you’re personally liable for all business debts. If the business is sued or can’t pay its bills, your personal assets — your house, your car, your savings — are on the line. Your business income is taxed at your personal marginal tax rate, which means as your income grows, so does your tax rate (up to 45% plus the Medicare levy).

Setting up a company

A company (Pty Ltd) is a separate legal entity. It has its own ABN, its own bank accounts, and its own legal obligations. You might be the sole director and shareholder, but the company is legally distinct from you.

The main draw is limited liability. If the company runs into financial trouble, your personal assets are generally protected. This is a significant advantage if your business carries any meaningful risk — whether that’s contractual obligations, potential lawsuits, or simply operating in an uncertain market.

Tax can be more favourable too. Companies pay a flat tax rate of 25% (for base rate entities with aggregated turnover under $50 million). If your business is earning well above that threshold on your personal tax rate, the difference can be substantial. You can also access more sophisticated tax planning strategies, like splitting income through wages and dividends.

The downsides are complexity and cost. Setting up a company costs more (ASIC registration fees, potential legal and accounting costs). You’ll need to maintain proper corporate records, hold annual reviews, and lodge a separate company tax return. Drawing money from the company needs to be done properly — you can’t just transfer cash to your personal account whenever you feel like it.

When to choose what

Stay as a sole trader if you’re just starting out and testing an idea, your business is low-risk and low-revenue, you want to keep things as simple as possible, or your total income (including business income) keeps you in a lower tax bracket.

Consider a company if your business income is consistently high (roughly $90,000+ in profit), you’re taking on contracts or clients where liability is a concern, you plan to bring on partners or investors down the track, or you want to reinvest profits in the business at a lower tax rate.

It’s not permanent

Here’s something many people don’t realise: your choice isn’t set in stone. Plenty of businesses start as sole traders and later transition to a company structure once they’ve grown. The transition involves some paperwork and cost, but it’s entirely normal and quite common.

The important thing is to choose the structure that fits where you are right now, not where you hope to be in five years. You can always evolve.

Get the right advice

While this guide gives you a solid overview, business structure decisions have tax and legal implications that are specific to your situation. It’s worth having a conversation with an accountant before you commit. A one-hour consultation could save you thousands in the long run.

Whatever structure you choose, make sure your accounting setup reflects it correctly from day one. Clean books from the start make everything easier — whether you’re a sole trader keeping it simple or a Pty Ltd building something bigger.
