Freelancing as a Sole Trader in Australia
Australia has a booming freelance economy. Most independent contractors start out as a Sole Trader because it is the simplest and cheapest business structure to set up. Under this model, you are the sole owner of the business, you make all the decisions, and you are legally responsible for all aspects of the business.
From a tax perspective, the Australian Taxation Office (ATO) does not separate your business income from your personal income. You declare all your business earnings on your personal income tax return and pay tax at standard progressive resident individual tax rates. Because your business profits are taxed at your personal rates, setting your rates accurately is key to maintaining a healthy take-home income.
Australian Resident Individual Tax Rates (2025/2026)
Australia uses a progressive tax bracket system. You only pay the higher tax rate on the portion of your income that falls within each bracket. The current resident tax brackets (incorporating the stage 3 tax cuts) are:
| Taxable Income (AUD) | Tax Rate | Tax Payable on Bracket |
|---|---|---|
| $0 – $18,200 | 0% | Nil |
| $18,201 – $45,000 | 16% | 16c for each $1 over $18,200 |
| $45,001 – $135,000 | 30% | $4,288 plus 30c for each $1 over $45,000 |
| $135,001 – $190,000 | 37% | $31,288 plus 37c for each $1 over $135,000 |
| $190,001+ | 45% | $51,638 plus 45c for each $1 over $190,000 |
In addition to standard income tax, most residents pay a Medicare Levy of 2.0% of their taxable income. If you do not have private hospital health insurance and earn over a certain threshold ($97,000 for singles), you may also be subject to the Medicare Levy Surcharge (MLS) of 1% to 1.5%.
Superannuation & GST Obligations
As a sole trader, you are not legally required to pay superannuation (retirement savings) to yourself. However, it is highly recommended to make voluntary contributions to secure your future. Voluntary super contributions can be claimed as a tax deduction up to standard limits, lowering your taxable income.
Another major milestone is the Goods and Services Tax (GST). If your gross freelance revenue (excluding GST) reaches or is expected to reach $75,000 AUD in a 12-month period, you must register for GST. Once registered, you must add 10% GST to your invoices for Australian clients and file quarterly Business Activity Statements (BAS) with the ATO.
Sole Trader Worked Example (AUD)
Let's look at the financial breakdown of a sole trader earning a gross revenue of $100,000 AUD with $10,000 of deductible business expenses, resulting in a taxable net profit of $90,000:
| Metric | Amount (AUD) | Description |
|---|---|---|
| Gross Billing / Revenue | $100,000 | Total invoiced amount (excl. GST) |
| Business Overhead & Expenses | −$10,000 | Rent, software, travel, etc. |
| Taxable Net Profit | $90,000 | Subject to personal tax |
| Income Tax (Stage 3 rates) | −$17,788 | Tax paid on progressive slabs |
| Medicare Levy (2.0%) | −$1,800 | Standard healthcare levy |
| Total Tax Liability | −$19,588 | Effective tax rate of ~21.7% |
| Net Take-Home Income | $70,412 | Real cash in hand after all taxes |
