How Sole Trader Tax Works
As a sole trader (ABN holder), you're taxed as an individual. Your business profit — income minus allowable deductions — is added to your personal income and taxed at marginal rates. There is no separate "business tax rate" for sole traders.
That is why many people searching for a sole trader tax rate, freelancer tax rate, or ABN tax rate are really looking for the personal tax outcome on business profit after deductions.
The Sole Trader Tax Calculation
Taxable Income = Business Income - Deductible Expenses - Voluntary Super
Total Tax = Income Tax + Medicare Levy + MLS (if applicable) + HELP (if applicable)
Take-Home Pay = Business Income - Expenses - Total Tax - Voluntary Super
If you're registered for GST, your income and expenses are converted to GST-exclusive amounts for income tax purposes. GST collected and credits are handled separately via your BAS.

Common Sole Trader Deductions
You can claim deductions for any expense directly related to earning your business income. Key categories include:
- Motor vehicle: Use the logbook method (business % of actual costs) or cents-per-km method (88c/km for 2025-26, capped at 5,000 km)
- Home office: Fixed rate method (67c/hour) or actual cost method for a dedicated workspace
- Phone & internet: Business portion based on usage records or a reasonable estimate
- Tools & equipment: Depreciation rules and temporary instant write-off settings can change, so check the ATO instant asset write-off page before assuming a current threshold
- Professional fees: Accountant, bookkeeper, legal advice, and tax agent fees
- Insurance: Public liability, professional indemnity, and income protection (business portion)
- Advertising & marketing: Website, social media, business cards, and online ads
How much tax should a sole trader set aside?
There is no universal percentage, because your result depends on profit, deductions, HELP, Medicare levy, and whether you make deductible super contributions. As a practical budgeting rule, many sole traders set aside part of each payment for tax and GST separately rather than waiting until year end.
Record keeping: Keep receipts and records for all business expenses for 5 years. The ATO's myDeductions app makes it easy to capture receipts on the go.
GST Obligations for Sole Traders
If your annual GST turnover is $75,000 or more, you must register for GST. Once registered:
- Add 10% GST to your invoices (price = ex-GST amount x 1.1)
- Claim GST credits on business purchases (input tax credits)
- Lodge a Business Activity Statement (BAS) — monthly, quarterly, or annually
- Remit net GST (GST collected minus GST credits) to the ATO
Net GST Payable = GST Collected on Sales - GST Credits on Purchases
Example: $110,000 income (inc. GST) with $22,000 expenses (inc. GST)
GST collected = $10,000 | GST credits = $2,000 | Net GST = $8,000
GST is separate from income tax. The GST-exclusive amounts are used to calculate your income tax liability.
PAYG Instalments
The ATO may require you to make quarterly PAYG instalment payments based on your estimated annual tax. This spreads your tax payments across the year rather than paying a lump sum at tax time.
- Quarterly due dates: 28 October, 28 February, 28 April, and 28 July
- Amount method: ATO provides an instalment amount based on your last return
- Rate method: Apply the ATO-provided rate to your actual business income each quarter
- Report on your BAS (Business Activity Statement)
First year tip: If this is your first year as a sole trader, set aside approximately 30% of profits for tax. You won't receive a PAYG instalment notice until after your first tax return.
Super for Sole Traders
Unlike employees, sole traders don't receive compulsory super contributions. However, you can make voluntary concessional contributions and claim them as a tax deduction:
- Concessional super cap: $30,000/year for 2025-26
- Contributions taxed at 15% inside the fund (usually less than your marginal rate)
- Tax saving = contribution x (your marginal rate + 2% Medicare - 15% super tax)
- Lodge a "Notice of intent to claim" with your super fund before lodging your tax return
FAQ
How is sole trader income taxed in Australia?
Sole traders pay individual income tax on their business profits (income minus allowable deductions). Your business profit is added to any other personal income and taxed at marginal rates. There is no separate business tax rate — you use the standard individual tax brackets, starting with a tax-free threshold of $18,200 for 2025-26.
Do sole traders pay company tax?
No. A sole trader is not a separate company for income tax purposes. You report business income in your individual tax return, and the net profit is taxed at individual marginal rates rather than the company tax rate.
Do I need to register for GST as a sole trader?
You must register for GST if your annual turnover is $75,000 or more ($150,000 for non-profit organisations). If your turnover is below the threshold, GST registration is optional but may benefit you if your clients can claim GST credits. Once registered, you charge 10% GST on sales and can claim GST credits on business purchases.
What expenses can a sole trader claim as deductions?
Sole traders can claim deductions for expenses directly related to earning business income. Common deductions include: materials and supplies, motor vehicle expenses, home office costs, phone and internet (business portion), tools and equipment, professional fees, insurance premiums, and advertising costs. You must keep records for 5 years.
What are PAYG instalments for sole traders?
Pay As You Go (PAYG) instalments are quarterly prepayments of your expected annual income tax. The ATO calculates your instalment amount based on your most recent tax return. You pay quarterly via your Business Activity Statement (BAS). This prevents a large tax bill at the end of the financial year.
Can sole traders contribute to superannuation?
Sole traders aren't required to pay super for themselves, but it's strongly recommended. You can make voluntary concessional (before-tax) contributions up to $30,000/year for 2025-26 and claim a tax deduction. Contributions are taxed at 15% inside the super fund, which is usually less than your marginal rate.
How do I calculate my take-home pay as a sole trader?
Take-home pay = Gross income (ex-GST if registered) - Business expenses (ex-GST) - Income tax - Medicare levy - Any MLS or HELP repayments - Voluntary super contributions. Unlike employees, sole traders must set aside money for tax payments throughout the year.
