How this calculator works

This tool will calculate the tax payable on a given taxable income for the income year 1 July 2012 to 30 June 2013. It can also calculate:

  • Medicare levy
  • Medicare levy surcharge
  • Higher Education Loan Program (HELP) repayment
  • Student Financial Supplement Scheme (SFSS) repayment, and
  • any tax offsets that may apply.

It will take these, along with other tax credits, into account in calculating the tax refund or debt.

  • Your taxable income for the 2013 income year (1 July 2012 to 30 June 2013).
  • 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.


This calculator will give you an estimate only, based on the information you enter at the time. The actual amount of your tax payable or refundable will depend on the information you provide in your tax return and on the balance of your account at the time of assessment.
