How are sole traders taxed in Australia?
The ATO treats you and your business as one legal entity. You don't lodge a separate business tax return. All income and expenses go on your individual tax return, reported using your personal tax file number.
Your taxable income is your business revenue minus allowable deductions. This figure is taxed at individual income tax rates. A 2% Medicare levy also applies on top.
Sole trader tax rates
The sole trader tax rate in Australia follows the same progressive brackets as individual taxpayers. For 2024 to 25, here are the rates for Australian residents:
- AUD $0 to AUD $18,200: 0%
- AUD $18,201 to AUD $45,000: 19c per dollar over AUD $18,200
- AUD $45,001 to AUD $120,000: AUD $5,092 plus 32.5c per dollar over AUD $45,000
- AUD $120,001 to AUD $180,000: AUD $29,467 plus 37c per dollar over AUD $120,000
- AUD $180,001+: AUD $51,667 plus 45c per dollar over AUD $180,000
The 2% Medicare levy is charged separately on top of these rates. Tax brackets for sole traders are identical to those for individual Australian taxpayers.
The tax-free threshold and the low-income tax offset
The tax-free threshold is AUD $18,200. You pay no income tax on earnings below this amount. If your income is low, you may qualify for the low-income tax offset.
Sole traders can also access the Small Business Income Tax Offset, capped at AUD $1,000 per year.
GST registration threshold and BAS obligations
Once your annual turnover reaches the AUD $75,000 threshold, GST registration is mandatory. After registering, you charge customers 10% GST on taxable sales. You report and pay that GST to the ATO via your BAS.
Most sole traders lodge a BAS quarterly. GST collected belongs to the ATO; it's never your income. Voluntary registration below the AUD $75,000 threshold is also possible. This lets you claim GST credits on business purchases, which can reduce costs if your expenses are high.
Key tax dates for sole traders
Knowing your deadlines helps you avoid ATO penalties. Here are the key dates to plan around:
- 31 October: Self-lodgement deadline for your individual tax return
- 15 May: Extended deadline when using a registered tax agent
- Quarterly: BAS due dates in January, February, April, and July, as well as PAYG instalment due dates for those enrolled
Missing these dates can trigger interest charges and penalties from the ATO.
The golden rule: What makes an expense tax deductible?
The ATO uses 3 criteria to assess every deductible expense. The cost must directly relate to earning your assessable income. It must not be private or domestic in nature. You must also hold records to prove it if audited.
If a cost has personal and business uses, claim only the business portion. Document the split and keep all relevant receipts. This is the foundation of paying taxes as a sole trader correctly.
A complete list of sole trader tax deductions in Australia
Understanding how to pay taxes as a sole trader means knowing which expenses reduce your taxable income. Below are the main deductions available. Always verify current ATO rules and consult a registered tax professional for your situation.
Home office expenses
Working from home creates deductible expenses. The ATO's fixed rate method lets you claim 70 cents per hour worked at home in 2024 to 25. This covers electricity, gas, internet, phone, and stationery.
Keep a complete record of all hours worked from home throughout the year. The actual cost method takes more effort but can result in a larger deduction.
Motor vehicle expenses
Car costs for business use are deductible. The cents per kilometre method applies a set rate, up to 5,000 business kilometres per year.
The logbook method tracks a 12-week period to establish your business-use percentage. This method often produces a higher deduction for frequent business drivers.
Business travel
Business travel costs, including flights, accommodation, and meals, are generally deductible. Keep an itinerary and supporting documents to prove the business purpose. Personal travel is not deductible, even if taken alongside a business trip.
Advertising, marketing, and promotional costs
Promotional spending is deductible when aimed at generating income. Google Ads, social media advertising, website hosting, and SEO tools all qualify. Sponsorships and branded merchandise are also claimable. The spend must clearly relate to your business activity.
Computer, phone, and technology expenses
Business-related technology costs are deductible. Laptops, software subscriptions, cloud storage, and business phone plans qualify. If a device is also used personally, claim only the business-use portion.
Office supplies and stationery
Everyday consumables used in your business are deductible as operating expenses. Printer ink, paper, and notebooks all count. Claim them in the year of purchase and keep your receipts.
Tools, machinery, and equipment
Tools and equipment used directly to earn income are deductible. Items used partly for personal reasons require a business-use calculation. Keep records showing how you arrived at the business portion.
Depreciating assets and instant asset write-offs
Large assets are normally depreciated over multiple years. The instant asset write-off lets eligible sole traders deduct assets costing under AUD $20,000 in the year of purchase. This applies to businesses with a turnover under AUD $10 million. Confirm current eligibility with the ATO before claiming.
Professional services
Fees paid to professional service providers for business-related advice are deductible. Accountants, lawyers, bookkeepers, and business consultants all qualify. Ongoing operational advice generally counts.
Fees for setting up a new legal structure may not qualify.
Professional memberships and subscriptions
Industry association memberships and relevant trade publications are deductible. The membership must relate directly to your current business activities. Subscriptions unrelated to your work don't qualify.
Self-education and professional development
Training directly related to your current business is deductible. Conferences, webinars, short courses, and relevant certifications all count. Courses aimed at a career change or unrelated field do not qualify.
Business insurance
Premiums for business-related insurance are deductible. Professional indemnity, public liability, and business contents insurance all qualify. Personal life insurance and private health coverage do not.
Protective clothing and uniforms
Safety gear required for your work, like steel-capped boots and hi-vis clothing, is deductible. Standard clothing worn to work is not deductible. Uniforms with a business logo that aren't suitable for everyday wear, such as scrubs, can qualify.
Wages, salaries, and superannuation
Wages, salaries, and superannuation contributions paid to employees are deductible. You must meet your PAYG withholding obligations. Non-compliant payments can be disallowed by the ATO.
Personal superannuation contributions
Sole traders don't receive compulsory employer superannuation. You can make voluntary superannuation contributions to your own fund and claim them as a deduction. These are taxed at 15% inside the fund, which is often below your marginal rate.
Bank fees, interest, and business loans
Fees on your business bank account are deductible. Interest on business loans or credit cards used for business also qualifies. You should keep business and personal accounts separate to make tracking straightforward.
Bad debts
If a client can't pay after genuine recovery efforts, you may write off the amount as a bad debt. The amount must have previously been included as assessable income. Write it off formally in the same income year you claim the deduction.
GST credits
If you're registered for GST, you can claim GST credits on eligible business purchases. Keep valid tax invoices to support every credit claim. Track input and output GST carefully for accurate BAS lodgement.
What expenses can't sole traders claim?
Some costs catch sole traders off guard at tax time. Common non-deductible expenses include:
- Personal and domestic costs such as groceries, clothing, and holidays
- Home loan repayments or mortgage interest
- Entertainment expenses not provided as a fringe benefit
- Traffic fines, penalties, and ATO interest charges
If your income is classified as personal services income, extra restrictions may apply to your deductions. Always check the ATO's guidelines if you earn the majority of your income from a single client.
When to claim deductions
Timing your claims correctly matters. Operating expenses, like phone bills and office supplies, are claimed in the year incurred. Capital expenses, like major equipment, are usually depreciated over multiple years.
The instant asset write-off is the key exception, allowing for an immediate deduction in the year of purchase. Check whether an item is operating or capital before claiming it.
How to claim tax deductions as a sole trader
Knowing how to pay taxes as a sole trader includes knowing where deductions are reported. You claim them in the Business and Professional Items schedule of your individual tax return. This is done via myTax on the ATO's myGov portal, or through a registered tax agent.
Self-lodgement is due by 31 October. Using a registered agent may extend your deadline to 15 May. Tax agent fees are also deductible.
How does a sole trader pay taxes? Through this annual return, plus PAYG instalments if the ATO requires it. The sole trader tax rate in Australia applies through your personal return, not a separate business rate.
Recordkeeping requirements for sole trader deductions
Good records aren't optional. The ATO requires a 5-year record retention period from the date you lodge your return. You need to hold onto the following as a minimum:
- Receipts and invoices for all business expenses
- Bank statements for your business account
- Logbooks for vehicle and home office claims
- Contracts, payroll records, and any relevant financial agreements
A profit and loss statement and balance sheet are also useful if you use accounting software. Digital records are accepted. You should scan paper receipts quickly to avoid losing them.
A dedicated business bank account makes tracking far easier and simpler from day one for you. Aspire is a solid choice for growing businesses seeking an all-in-one solution.
