Zone or Overseas Forces Offset (shz)

Click label R at item T4 to open the Zone, Overseas Forces offset selection screen.

The zone tax offset is made up of three amounts:

  • the fixed amount for the relevant zone, plus

  • a percentage of a base amount, plus

  • the invalid spouse or carer, invalid relatives, parents/parents-in-law claimed at item T6 invalid and carer.

Eligibility to claim the Zone or Overseas forces tax offsets

To claim the Zone or the Overseas forces tax offsets, you must have resided in the Zone as well as working in the Zone.

To qualify for the Zone tax offset, your usual place of residence must have been in a remote area (not necessarily continuously) for:

  • 183 days or more during 2018–19, or
  • 183 days or more during the period 1 July 2017 to 30 June 2019 (including at least one day in 2018–19) and you did not claim a zone tax offset in your 2018 tax return.

To qualify for an overseas forces tax offset the taxpayer:

  • must have served in a specified overseas locality as a member of the Australian Defence Force or a United Nations armed force in the current income year, AND
  • the income relating to that service was not specifically exempt from tax.

Periods of service for which the income was 'exempt foreign employment income' are excluded in working out eligibility for the tax offset.

If the overseas service was less than 183 days, you may be able to claim part of the tax offset.

To claim the full overseas forces tax offset:

  • You must have served in the overseas locality for 183 days or more in the current income year, OR

  • The total number of days you served in the overseas locality, when added to the number of days spent in one or more zones, equals 183 days or more.

  • Your invalid spouse or carer

  • Your or your spouse's invalid carer parent

  • Your or your spouse's invalid, child, brother or sister (an invalid relative)

Remote area allowance Enter any amount of remote area allowance received from Centrelink or the Department of Veterans' Affairs or the equivalent amount that was included in an exceptional circumstances relief payment. Such an amount will reduce the Total offset calculated.
