Calculate Your Income Tax, Tax Refund or Tax Payable

If tax withheld is more than your estimated tax liability, you may receive a refund. If it is less, you may have tax payable.

Tax Calculators are a great way to estimate your tax refund or track your taxes during the financial year. A tax calculator provides the ability to add your wages, your tax withheld and your deductions. The Tax Return Calculator then provides an estimate of your tax payable or tax refundable.
If you’re using tax calculators to estimate your tax during the year, remember a tax calculator calculates on an annual basis. You’ll have to estimate your full year position for the tax calculator.
You can run a tax calculator multiple times to work out how to increase your tax refund or reduce / remove a tax payable position. Keep updating the tax deductions section to see your tax refund increase! Remember, tax calculators provide an estimate of your tax position, they are indicative only and do not take into account all of your personal circumstances.
