    How much tax should a sole trader set aside?

    If you’re self-employed, freelancing or operating as a sole trader in Australia, tax generally isn’t automatically deducted from the money your clients pay you. That means it’s useful to estimate how much of each payment should be put aside for tax.

    Geoffrey’s Australian tax calculator gives you a quick estimate of income tax, Medicare levy, HELP repayments and GST, depending on the options you select.

    Who is this tax calculator for?

    • Australian sole traders
    • Freelancers and contractors
    • Small business owners
    • Employees wanting to estimate their tax
    • People with a HELP or HECS study debt
    A useful budgeting tool rather than tax advice.

    Your actual tax position can be affected by deductions, offsets, business expenses, residency and your individual circumstances. Use the calculator as an estimate and confirm important figures with the ATO or a registered tax agent.

    How does the Australian tax calculator work?

    Enter your income and select whether you earn it weekly, fortnightly, monthly or annually. You can then choose whether you’re an employee or sole trader and include options such as GST registration and HELP/HECS repayments.

    The calculator then estimates the amount you may want to set aside and shows the major components separately, making it easier to see where the money is going.

    Sources & updates: Tax thresholds and repayment settings are based on information published by the Australian Taxation Office. Calculator reviewed August 2026.
