Most sole traders start as sole traders because it's easy. One ABN, no setup costs, minimal admin. That's fine when you're starting out. It's worth revisiting once things are actually working.
The question isn't whether you should restructure. It's when the cost of not restructuring starts to outweigh the hassle of doing it.
A few things usually trigger the conversation. The first is tax. As a sole trader, every dollar of profit is taxed at your personal income tax rate. Once you're earning consistently above $100k, a company or trust structure can start to make sense. Not always, but often.
The second is liability. Sole traders have no separation between their personal and business assets. If something goes wrong, a client dispute, an accident, a bad debt, your personal finances are exposed. A company creates a legal separation.
The third is perception. Some clients, particularly larger businesses, are more comfortable contracting with a company than an individual. It's not always rational but it's real.
Restructuring isn't free. There are setup costs, ongoing compliance, and more complexity to manage. But done at the right time, it saves money and reduces risk. Done too early, it's just paperwork.
If your business is growing and you haven't revisited your structure in the last two years, it's worth a conversation.
