Sole Trader Tax in Australia — Key Facts
As a sole trader, you pay tax on your net business profit at individual income tax rates — there's no separate company tax rate. Your tax obligations include:
- Income tax: Paid annually on net profit at marginal rates (19%–45% plus Medicare levy)
- GST: Mandatory if turnover exceeds $75,000/year — register within 21 days of crossing the threshold
- PAYG instalments: Quarterly tax prepayments to avoid a large end-of-year bill
- Superannuation: Not mandatory for sole traders, but concessional contributions are tax-deductible
2025–26 Australian Tax Rates
The 2025–26 income tax rates for Australian residents (including sole traders) are:
- $0–$18,200: Nil (tax-free threshold)
- $18,201–$45,000: 19 cents per $1 over $18,200
- $45,001–$135,000: $5,092 + 32.5 cents per $1 over $45,000
- $135,001–$190,000: $34,342 + 37 cents per $1 over $135,000
- $190,001+: $54,842 + 45 cents per $1 over $190,000
The Medicare Levy of 2% applies to most taxpayers. The Low Income Tax Offset (LITO) of up to $700 applies to incomes under $66,667.
GST and BAS — What Sole Traders Need to Know
Once your annual turnover reaches $75,000, you must register for GST and lodge a Business Activity Statement (BAS) — either monthly, quarterly or annually. The standard GST rate is 10%. As a registered business, you collect GST on sales and can claim GST credits on business purchases, remitting the net amount to the ATO.
Capital Gains Tax in Australia
CGT applies to assets sold at a profit including property, shares, and cryptocurrency. If you've held the asset for more than 12 months, you're entitled to a 50% CGT discount — meaning only half the gain is added to your taxable income. CGT is not a separate tax; it forms part of your income tax assessment.
