Australian Sole Trader Tax Obligations 2025-26
As a sole trader in Australia, you report your business income and expenses in your individual tax return. Your taxable income is calculated as your gross business income minus allowable business deductions, plus any other income you earn (such as salary from employment, interest, or rental income).
For the 2025-26 financial year (1 July 2025 to 30 June 2026), the ATO applies individual income tax rates to your total taxable income. Australian residents benefit from a tax-free threshold of $18,200, meaning no tax is payable on the first $18,200 of taxable income. The marginal rates then increase progressively from 16% through to 45% for income over $190,000.
Common sole trader deductions include home office expenses, motor vehicle costs, equipment depreciation, professional development, insurance premiums, accounting and legal fees, advertising, and phone and internet expenses. You must keep records of all deductions for at least five years and only claim expenses that are directly related to earning your business income.
Sole traders with an annual GST turnover of $75,000 or more must register for GST and lodge Business Activity Statements (BAS). Even below this threshold, you may choose to register voluntarily. PAYG instalments may also apply if your expected tax liability exceeds certain thresholds. All calculations on this page run entirely in your browser with no data sent to any server.

Common deductions include home office expenses, vehicle and travel costs, equipment and tools, professional development, insurance, accounting fees, advertising, phone and internet costs, and depreciation on business assets. You must keep records of all expenses claimed.
When do sole traders need to lodge their tax return?
If you lodge your own tax return, it is due by 31 October following the end of the financial year (30 June). If you use a registered tax agent, you may be eligible for an extended deadline, typically up to 15 May the following year. Sole traders with a GST turnover of $75,000 or more must also lodge Business Activity Statements (BAS) quarterly or monthly.
What is the Medicare Levy Surcharge for sole traders?
The Medicare Levy Surcharge (MLS) is an additional 1% to 1.5% charge on top of the standard 2% Medicare levy. It applies to Australian residents who earn above $93,000 (for singles) and do not have an appropriate level of private hospital cover. The surcharge encourages higher-income earners to use the private health system, reducing demand on the public system.
