At some point, every growing business in the Hills District hits the same wall. Turnover is climbing, income is getting harder to predict, and the question that used to seem abstract suddenly isn’t: should I still be operating as a sole trader?
Most people who ask this question already sense the answer. They’ve heard the company tax rate of 25% and they know their personal marginal rate is higher. They’ve had someone mention a trust structure at a barbecue in Kellyville and they didn’t really follow but it sounded like it mattered. And they haven’t done anything about it because changing your business structure feels like it should require a law degree and three months of admin.
It doesn’t. But getting the decision right does require talking to a tax accountant in Bella Vista who understands more than just the compliance side.
What Sole Trader Actually Means for Your Tax Bill
As a sole trader, your business income is your personal income. Every dollar the business earns gets added to your individual return and taxed at your marginal rate. If you’re earning $120,000 from your trade or practice, you’re paying income tax at 37 cents on every dollar above $135,000 — but the income stacks on top of any salary, rental income, or other earnings you already have.
For a lot of people in the early stages of a business, this is fine. The admin is simple, the compliance costs are low, and the tax bill reflects what the business actually earned. The problem is that sole trader structures have no flexibility. You can’t split income with a spouse. You can’t retain profits in the business at a lower rate. Everything flows straight through to you.
That works until it doesn’t.
The Company Structure — What You Actually Get
A company pays tax at the small business rate of 25% on retained earnings — versus the 39% effective rate a high-earning individual might face. That gap is where the savings are. If your business earns $200,000 and you only need $120,000 to live on, leaving $80,000 in the company instead of drawing it all out and paying personal tax on it can be the difference between a good year and a great one.
Companies also provide genuine liability protection. Your personal assets — the family home in Bella Vista, the investment property in Norwest — sit at more distance from business debts and disputes. That’s not hypothetical. It’s one of the main reasons Hills District tradies, consultants, and allied health professionals start considering the switch once they’re past the $250K revenue mark.
The tradeoff is real too. A company means a separate tax return, director obligations, annual fees, and a bit more accounting work each year. Whether that overhead is worth it depends entirely on the numbers — and the numbers look different for a plumber in Rouse Hill than they do for a physiotherapist with two clinics in the Norwest medical precinct.
What About a Trust?
Discretionary trusts are the structure of choice for a lot of Hills District family businesses, particularly where both spouses are involved in the business or where there are multiple family members who could reasonably receive income.
The appeal is income splitting — distributing profits to family members in lower tax brackets to reduce the overall family tax burden. A trust can distribute income to a spouse, adult children, or a related company, and when done correctly, the tax savings are legitimate and substantial.
Trusts are more complex than companies and the ATO watches income splitting arrangements closely. Getting this wrong is expensive. Getting it right, with proper tax planning in Bella Vista from an accountant who understands the current ATO guidance, can save a family business tens of thousands annually.
How to Actually Decide
There’s no universal answer. The right structure depends on your current income, your growth trajectory, whether you have a spouse or family members involved, your industry (some have specific risks that make liability protection more pressing), and how much complexity you’re comfortable managing.
What I’d say is this: if your business is turning over more than $200,000 a year and you haven’t reviewed your structure in the last three years, you’re probably leaving money on the table. The question isn’t whether a review is worth doing — it is. The question is just when.
The best starting point is a one-on-one strategy session with an accountant in Castle Hill or Bella Vista who can model out the actual numbers for your situation. Not general advice. Your numbers, your family, your goals.
That’s the conversation worth having.
