Sole Trader or Pty Ltd: Choosing the Right Structure for Your Trade Business
4 September 2026 · 6 min read · By Heaney Accounting
Why Structure Matters for Tradies
When you first start out, operating as a sole trader is simple and cheap. However, as your business grows, handles more liability, and hits higher profit margins, a company structure often becomes the smarter move.
The Key Differences
- Sole traders have unlimited liability, meaning personal assets are at risk if things go wrong.
- Companies act as a separate legal entity, providing a protective wall between your personal life and business risks.
- Companies pay a flat tax rate on profits, whereas sole traders pay tax at their personal marginal rate.
- Setting up a Pty Ltd company requires more paperwork, ASIC registration, and formal accounting processes.
Important Note: If you are taking on bigger commercial contracts with higher liability, moving to a company structure is often a requirement rather than just a choice.
- Review your current annual profit and tax liability.
- Assess the level of risk in your daily trade operations.
- Calculate the extra costs of compliance, such as company tax returns and ASIC fees.
- Discuss the potential long-term benefits with your accountant.
Making the switch shouldn't be rushed. It is worth doing a mid-year check to see if the administrative load of a company is offset by the potential tax savings and asset protection it offers.
