How to Structure Your Small Business: Sole Trader vs. Company

The Core Distinction: Separate Legal Personality

The fundamental difference between operating as a sole trader and operating through a company is the concept of separate legal personality. A company incorporated under the Corporations Act 2001 (Cth) is a distinct legal entity – it can enter contracts, own assets, incur liabilities, and sue and be sued in its own name. A sole trader, by contrast, is not legally separate from the business. The individual and the business are, in law, one and the same. This distinction has profound implications for personal liability, taxation, and the long-term structure of your enterprise.

As a sole trader, your personal assets – your home, your savings, your car – are available to satisfy any business debts or legal judgments against you. There is no corporate veil to protect you. As a company director and shareholder, you generally enjoy limited liability, meaning your exposure is limited to the amount you have invested in the company (subject to important exceptions, including personal guarantees, insolvent trading, and breaches of directors' duties).

Tax Considerations

Sole traders are taxed at individual marginal rates on their business income, which can reach 47% (including the Medicare levy) for high earners. Companies are taxed at the corporate rate – currently 25% for base rate entities with an aggregated turnover below $50 million, and 30% for larger companies. This rate differential can create opportunities for tax deferral and income splitting when profits are retained in the company rather than distributed as dividends.

However, the tax picture is more nuanced than the headline rate comparison suggests. Sole traders have access to the 50% capital gains tax discount for assets held more than 12 months; companies do not. Sole traders can also access the small business CGT concessions directly, whereas using those concessions through a company requires careful structuring. The interaction between company tax, franking credits, and personal income tax when dividends are paid also needs to be carefully modelled. A tax adviser who understands both the legal and accounting dimensions of business structuring is invaluable here.

Administration and Compliance

Operating as a sole trader is administratively straightforward. You register a business name with ASIC (if trading under a name other than your own), obtain an ABN, and lodge your business income as part of your individual tax return. There are no annual ASIC fees, no requirement to maintain company registers, and no obligation to prepare financial statements in a particular format.

A company, by contrast, carries ongoing compliance obligations. These include lodging an annual company tax return with the ATO, paying an annual ASIC review fee, maintaining a register of members and officeholders, notifying ASIC of changes to directors and shareholders, and complying with the reporting and governance requirements of the Corporations Act. For small businesses, these obligations are manageable – but they are real, and the administrative burden should be factored into your decision.

Which Structure Is Right for You?

There is no one-size-fits-all answer. For very early-stage businesses with low turnover and minimal liability exposure, operating as a sole trader may be entirely appropriate, at least initially. For businesses with meaningful revenue, physical or professional liability risks, multiple founders, or plans to bring on investors, a company structure typically offers important advantages. Many business owners find that a company combined with a discretionary (family) trust as the shareholder creates the greatest flexibility for income distribution and asset protection – though this adds further complexity and cost. We recommend seeking legal and accounting advice before committing to any structure, particularly if you are entering into significant contracts or taking on staff.
