  • Income tax estimator

    This calculator will help you work out your tax refund or debt estimate for the previous four years. It will estimate your tax payable and also calculate your:

    • Medicare levy
    • Medicare levy surcharge
    • Higher Education Loan Program (HELP) / Student Start-up Loan (SSL) / Trade Support Loan (TSL) repayment
    • Student Financial Supplement Scheme (SFSS) repayment
    • any tax offsets that may apply.

    It will take these, along with other tax credits into account when estimating your tax refund or debt.

    Information you will need:

    • total gross income payments you received
    • total amount of tax that was withheld
    • total amount of deductions to claim
    • your residency status for taxation purposes
    • details of your tax credits and any tax offsets you are entitled to claim.

    You may need additional information, depending on your circumstances and what you choose to calculate.

    What's new for 2018-19

    You may be eligible for a new low and middle income tax offset if:

    • you are an Australian resident for income tax purposes, and
    • your taxable income is in the appropriate income range.

    The offset does not reduce your Medicare levy, but it reduces the income tax you pay, even down to zero.

    You do not need to claim this offset; we will work it out for you.
