Tax for Self-Employed Australians 2025: What You Need to Know
Over 2.4 million Australians operate as sole traders — the simplest business structure with no separate legal entity. As a sole trader, your business income is your personal income: you pay income tax at personal rates, Medicare levy, and manage GST and super yourself. Understanding your tax obligations is critical for avoiding surprises at tax time.
Key Self-Employment Tax Obligations
- Income tax: Paid at personal rates on net profit (revenue minus deductible expenses)
- Medicare levy: 2% on taxable income (1–1.5% MLS surcharge may apply if no private hospital cover above $93,000)
- GST: Must register if turnover exceeds $75,000/year; collect 10% GST and lodge BAS quarterly
- Super: Not legally required for sole traders, but concessional (before-tax) contributions up to $30,000/year are tax-deductible
- PAYG instalments: ATO may require quarterly tax prepayments once income exceeds certain thresholds
Top Deductions for Sole Traders 2025
| Deduction | Notes |
|---|---|
| Home office expenses | 67c/hour fixed rate OR actual expenses method |
| Vehicle expenses | Logbook method or 85c/km (cents per km) |
| Equipment and tools | Instant asset write-off up to $20,000 (2025) |
| Professional development | Courses, conferences, subscriptions |
| Professional fees | Accountant, bookkeeper, legal |
| Super contributions | Personal concessional contributions — fully deductible |
Not tax advice. Consult a registered tax agent for your specific situation. Deductibility depends on individual circumstances.
Frequently Asked Questions
How much tax do self-employed people pay in Australia?
Self-employed Australians pay income tax at the same personal rates as employees — 0% up to $18,200, 19% from $18,201–$45,000, 32.5% from $45,001–$135,000, and so on — plus 2% Medicare levy. The key difference is that business expenses are deductible before tax is calculated, and there's no employer withholding — you're responsible for putting aside tax throughout the year.
Do I need to register for GST as a sole trader?
You must register for GST if your annual business turnover is $75,000 or more (or $150,000 for non-profit organisations). Once registered, you collect 10% GST on your invoices and remit it to the ATO (minus any GST credits on business purchases). You must lodge a Business Activity Statement (BAS) — usually quarterly.
Can self-employed people claim super contributions as a tax deduction?
Yes — this is one of the best tax strategies for sole traders. You can make personal concessional (before-tax) super contributions and claim them as a deduction, up to the $30,000 annual concessional cap. A $10,000 super contribution at a 37% marginal rate saves $3,700 in income tax while building your retirement savings.
