Sole trader tax calculator: how much to set aside (2026–27)

Short answer
On A$100,000 of ABN income and A$20,000 of expenses, set aside about A$1,343.33 a month for tax in 2026–27 (A$16,120 a year, 16.1% of what you earn), and keep about A$63,880. The estimate covers income tax and the Medicare levy and applies in every state. The calculator takes your ABN income and expenses, adds any wages, and works out the tax, Medicare levy and HELP repayment your business adds, using ATO rates for 2026–27. It shows what to put aside each month or quarter and what you keep. It also compares you with an employee on the same pay. Enter your own numbers below.

The employee column treats your ABN income as a salary, with no super in it and no work expenses. Paid leave and other employment entitlements are not valued, so the comparison is about tax and super only.

How sole trader tax works

A sole trader pays income tax on business profit, which is business income less deductible expenses. The profit is added to any other income, such as wages, and taxed at the same rates as everyone else. Medicare levy and any HELP repayment are worked out on the total.

Clients generally pay an ABN invoice in full, so the tax is yours to put aside. The calculator takes the tax on your wages and profit together, subtracts the tax on your wages alone, and shows the difference as the tax your business adds. Divide it by 12 or 4 for a monthly or quarterly amount.

Example: A$100,000 of income and A$20,000 of expenses leaves A$80,000 of profit. Tax and Medicare levy come to A$16,120 in 2026–27, so you keep A$63,880, and set aside A$1,343.33 a month.

If the ATO sends you PAYG instalment notices, pay the amounts on them. This calculator does not work those out; it shows the tax for the whole year.

Income tax rates 2026–27: the same in every state

Income tax is federal, so a sole trader in NSW, VIC, QLD, WA, SA, TAS, the ACT or the NT pays the same. Most people also pay the 2% Medicare levy; people on low incomes pay less or none.

GST and the A$75,000 threshold

You must register for GST when your GST turnover (gross business income minus GST) is A$75,000 or more, or when you start a business and expect to reach it in your first year. Taxi, limousine and ride-sourcing drivers must register whatever their turnover. Below the threshold registering is optional.

The calculator uses income before GST, because GST you collect is not your income. Use the GST calculator to add GST to a quote.

Super for sole traders

The calculator assumes no employer pays super on your business profit, so saving for retirement is your choice. Personal contributions you claim as a tax deduction count towards the general concessional cap, which is A$32,500 in 2026–27 and includes any super an employer pays on your wages. The calculator does not include voluntary contributions, so your tax would be lower if you made one. If you are unsure whether your work counts as employment for super, ask the ATO.

ABN or employee on the same pay

The table under the calculator compares your result with an employee who earns the same amount as a salary. The income tax is the same on the same taxable income. The differences are the expenses an ABN carries, and the employer super of 12% an employee gets on top. Paid leave and other entitlements are not valued.

To compare two offers, enter the ABN rate above and set expenses to what you expect to spend, then compare it with the pay calculator for the salary.

Common questions

It depends on your profit. On A$80,000 of profit and nothing else, an Australian resident pays about A$16,120 including the Medicare levy in 2026–27, which is 20.2% of profit. The calculator works out your own share from your income, expenses and any wages.
