Our calculator will take between 5 and 20 minutes to use.

What you can do with this calculator

This calculator will help you work out your eligibility for a zone or overseas forces tax offset and the tax offset amount that you can claim. It can be used for the 2014–15 to 2022–23 income years.

The results of this calculator are based on the information you provide. You should use these results as an estimate and for guidance purposes only.

From 1 July 2015, to be eligible for the zone tax offset your usual place of residence must be in a zone. If your usual place of residence was not in a zone, you are not eligible for the zone tax offset.

For earlier years, you only had to have lived or worked in a remote or isolated area of Australia (zone), not including an offshore oil or gas rig.

You may be able to claim an overseas forces tax offset if you have served overseas as a member of the Australian Defence Force or a United Nations armed force.

If you qualify for both an overseas forces tax offset and a zone tax offset, you can claim only one of them. The calculator will work out which offset gives you the greatest benefit.

What you will need

For the period you are calculating, you will need:

  • The number of days you usually lived or worked in a zone or specified overseas locality.
  • If you maintained a child under 21 or full-time student under 25  
  • Your prior year zone and claim details if you are claiming for a zone tax offset and you lived or worked in a zone for less than 183 days.
