📝 Real Example
Anna is a freelance graphic designer just starting out. She chooses a sole trader structure to keep costs low and simplify her tax lodgement. After three years, as her business grows and she hires two designers, she restructures into a company for asset protection and better tax management.
🔐 Can You Change Your Structure Later?
Yes — many Australian businesses begin as sole traders and then evolve into a company or trust as they grow. A tax adviser can guide you through a smooth and compliant transition.
💡 Pro Tip: Always register your business name and apply for an ABN (Australian Business Number), no matter which structure you choose.
