Understanding the Tax Implications of Trading as a Company

26 August 2026 · 6 min read · By Heaney Accounting

Many tradies start as sole traders because it is simple, but moving to a company structure is a major milestone for growing businesses. This shift changes how you pay tax, how you handle profit, and what you are legally responsible for.

Company Tax vs Personal Income Tax

As a sole trader, you pay tax on business profit at your personal tax rate. As a company, the business is a separate legal entity that pays its own tax on profits, usually at a flat rate, which can offer significant planning advantages.

  • Companies pay a flat tax rate on profits regardless of your personal bracket
  • You must pay yourself a salary or draw dividends, which are taxed differently
  • There is more rigorous record-keeping required for company directors
  • Asset protection is generally stronger within a company structure

Important Note: Always consult with an accountant before changing your business structure, as the setup costs and ongoing compliance reporting can be significant.

  1. Apply for a new ACN and ABN for the company
  2. Open a separate business bank account in the company name
  3. Update your insurance policies and licenses to the new company entity
  4. Notify your existing clients and suppliers of the change in trading status

While the extra paperwork might seem daunting, it is often a necessary step to protect your personal assets and provide a scalable foundation for your business growth.
