Zone tax offset

Eligibility for the zone tax offset is based on your usual place of residence. If your usual place of residence was not in a zone, you are not eligible for the zone tax offset.

Example: residence not in a remote area

Michael is a maintenance engineer contractor who lived in Brisbane (not located in a zone). He flew to Blackall in Queensland (located in Zone B) where he worked in the mining industry.

As Michael's usual place of residence was not in a zone, he is not eligible for the zone tax offset.

End of example

 

Example: residence in a remote area

Louise lived in Darwin (located in Zone A). She travels to Kununurra in Western Australia (located in a Zone A special area) for her job in the mining industry.

Louise drove to Kununurra, completed a 14 day shift at the mine, and then drove back to Darwin at the end of her working shift, where she remained for 16 days.

As Louise's usual place of residence was Darwin (Zone A), she is eligible for the zone tax offset for Zone A.

End of example

Remote areas are classed as either Zone A or Zone B. There are also special areas within these zones. If you do not know which zone your area is in, see Australian zone list.

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

  • 183 days or more during 2022–23, or
  • 183 days or more during the period 1 July 2021 to 30 June 2023 (including at least one day in 2022–23) and you did not claim a zone tax offset in your 2022 tax return.

If your usual place of residence was in a zone for less than 183 days in 2022–23, you may still be able to claim a tax offset as long as your usual place of residence was in a zone for a continuous period of less than 5 years after 1 July 2017 and:

  • you were unable to claim in the 1st year because you lived there less than 183 days, and
  • the total of the days you lived there in the first year and in 2022–23 is 183 or more. The period you lived in a zone in 2022–23 must include 1 July 2022 (the first day of the income year).

Example: remote area for a continuous period of less than 5 years

Garry lived in a remote area from 1 March 2018 to 30 September 2022, a continuous period of less than 5 years.

He couldn’t claim a zone tax offset for the first year because he lived there for only 122 days. However, he could carry forward these unused days to 2022–23. He now adds the number of days from 1 March 2018 to 30 June 2018 (122 days) and the number of days from 1 July 2022 to 30 September 2022 (92 days). As the total (214 days) is ‘183 days or more’ over those two income years, Garry can claim the tax offset in his supplementary tax return 2023.

End of example

Overseas forces tax offset

You may be eligible for an overseas forces tax offset if you served in a specified overseas locality as a member of the Australian Defence Force or a United Nations armed force in 2022–23 and income relating to that service was not specifically exempt from tax. Periods of service for which your income was ‘exempt foreign employment income’ are excluded in working out your eligibility for the tax offset.

Your employer will be able to advise you whether you served in a locality that qualifies for the overseas forces tax offset. You can also see which localities qualify for the overseas forces tax offset at Specified overseas localities or contact us.

To claim the full tax offset, you must have served in the overseas locality for 183 days or more in 2022–23. If your overseas service was less than 183 days, you may be able to claim part of the tax offset. Unlike the zone tax offset, you cannot carry forward any unused days from previous years to make up 183 days.

If you served in an overseas locality for less than 183 days, but the total number of days served in the overseas locality, when added to the number of days served in one or more zones, is 183 days or more, you may still be entitled to claim the full overseas forces tax offset. If you served as a member of the Australian Defence Force, days spent in a zone must be defence force service.

If you qualify for both an overseas forces tax offset and a zone tax offset, you can claim only one of them. Claim the higher one.

Completing your supplementary tax return

The zone or overseas forces tax offset is made up of:

  • a fixed amount
  • a base amount.

The fixed amount is a prescribed amount available to all people in the zone or overseas area eligible for the tax offset.

You may be able to include a base amount if you:

Your fixed and base amounts are determined by your circumstances.

How to work out your tax offset if your circumstances were simple

Step 1

Your tax offset is the amount in Table 1 if:

  • your usual place of residence was in only one zone or you served in only one specified overseas locality for at least 183 days
  • you are not able to include a base amount as
    • you were not entitled to claim the invalid and invalid carer tax offset
    • you either did not have a dependent child or student at any time in 2022–23, or if you did have a dependent child or student, their adjusted taxable income (ATI) was equal to or greater than $282 plus $28.92 for each week you maintained them.

Child includes your adopted child, stepchild, ex-nuptial child and child of your spouse. See the definition of child in Special circumstances and glossary 2023.

A student must be full-time at a school, college or university.

If you cannot use Table 1 you will need to work through How to work out your tax offset if your circumstances were more complex.

If you received a remote area allowance from Centrelink or the Department of Veterans’ Affairs you must reduce the amount of your zone tax offset by the amount you received for this allowance.

Step 2

Write your tax offset amount less any remote area allowance at question T4 – label R on page 16 of your tax return. Do not show cents. Go to question T5 Invalid and invalid carer 2023.

How to work out your tax offset if your circumstances were more complex

You can either use our Zone or overseas forces tax offset calculator or see Working out your total base amount.

The following information will help you work out your base amount, if any.

Dependent child or student base amount

Full-year claim

Your base amount will include the maximum amount shown in Table 2 for each student under 25 years old on 30 June 2023 in full-time education at a school, college or university, and for each child under 21 years on 30 June 2023 who, for the whole of 2022–23:

  • was treated as an Australian resident
  • was maintained by only you, and
  • had an ATI of less than $286.

To calculate the ATI see Adjusted taxable income for you and your dependants 2023 or use the Income tests calculator.

If you did not have any dependent children or students, go to Invalid and invalid carer base amount.

For the meaning of dependant, see Special circumstances and glossary 2023.

If all of these requirements were met, add up the base amount for each child or student and write the total at row a Worksheet 4.

If 2 or more people contributed to the maintenance of a dependent child or student, each person can only claim a proportion of the base amount.

For the meaning of maintaining a dependant, see Special circumstances and glossary 2023.

If the requirements were met for only part of the year, or your child’s or student’s ATI for the period you are claiming this base amount in respect of them was $286 or more, you may be able to claim for a part of the base amount. Read on.

Part-year claim

You can claim only part of the base amount for dependent children or students if:

  • the child or student was treated as an Australian resident for only part of 2022–23
  • the student was under 25 years old and in full-time education for only part of 2022–23
  • the child or student was maintained by you for only part of 2022–23
  • the child was 21 years old at 30 June 2023 and not in full-time education, or
  • the student was 25 years old at 30 June 2023.

Use Worksheet 1 to work out the reduced base amount for each eligible dependent child or student as described in Table 2.

If the ATI of your child or student was less than $286 for the period you are claiming this base amount in respect of them, transfer amount at row e above to row b Worksheet 4.

If you had more than one eligible child or student and the ATI of each one was less than $286 for the period you are claiming this base amount in respect of them, work out the amount for each child and student, add up all the amounts and write the total at row b Worksheet 4.

If ATI was $286 or more for the period you maintained them

You cannot claim any base amount for your child or student if that child or student had an ATI equal to or greater than:

  • the total of $282 plus $28.92 for each week you maintained them for a student under 25 years old or for the oldest child under 21 years old who is not a student, or
  • the total of $282 plus $21.70 for each week you maintained them for any other child under 21 years old who is not a student.

If your child’s or student’s ATI for the period you are claiming this base amount in respect of them was $286 or more but less than the limits shown, use b to work out the base amount.

Sole parent base amount

If you had sole care of a dependent child or student and you have written an amount of at least $1 in Worksheet 4 at rows a, b or c (base amount for dependent children or students), you may also be eligible for a sole parent base amount.

You can only claim this base amount if you were a sole parent at any time during 2022–23 and:

  • your usual place of residence was in a remote area of Australia, or
  • you served overseas as a member of the Australian Defence Force.

Sole care means that you alone had full responsibility on a day-to-day basis for the upbringing, welfare and maintenance of a child or student. We do not consider you to have had sole care if you were living with a spouse (married or de facto) during the year unless special circumstances exist.

You will need to use Worksheet 3 to calculate a part-year sole parent base amount claim.

Special circumstances

If you had a spouse (married or de facto) at any time during 2022–23, you are entitled to a sole parent base amount only in special circumstances.

Generally, for special circumstances to exist, you must have been financially responsible for and have had sole care of the dependent child or student, without the support a spouse normally provides.

Examples of situations where special circumstances may arise:

  • You were married at any time during 2022–23 but
    • during 2022–23, you then separated from, or were deserted by, your spouse, and
    • for the remainder of 2022–23, you were not in a de facto relationship.
     
  • Your spouse was in prison for a sentence of at least 12 months.
  • Your spouse was medically certified as being permanently mentally incapable of taking part in caring for your child or student.

If you are unsure whether special circumstances applied, contact us.

Shared or joint custody after a relationship breakdown

There are times, after a relationship breakdown, such as a divorce or separation, where both parents share the custody of a child or student.

If you can show that you had sole care of a dependent child or student for part of the year, you may be able to claim the base amount for that part of the year. This means more than just having access visits with the child or student.

We consider you to have had sole care of the child or student for the part of the year up to the day the child turned 21 years old, or the student turned 25 years old if the dependant:

  • was not receiving full-time education and turned 21 years old during 2022–23, or
  • was a full-time student and turned 25 years old during 2022–23.

You are only entitled to claim the base amount for that part of the year before the birthday.

If you had sole care of a child or student for the whole of 2022–23, write $1,607 at row d Worksheet 4.

Final calculation

Multiple locations

Check Table 3 if:

  • your usual place of residence was in more than one zone or special area, or
  • you serve in specified overseas localities, and
  • you were in one of them for 183 days or more.

If the fixed amount for that zone is higher than for the other zones where you were, use that fixed amount and Worksheet 5 to work out your tax offset. This will give you the greatest benefit.

Otherwise go to Category 2.

Example: using a fixed amount for a zone

Neil's usual place of residence was in Zone A for 190 days and in Zone B for 40 days. Table 3 shows that the fixed amount for Zone A is higher than the Zone B amount. Neil uses the Zone A amount because this will give him the greater benefit. He ignores the time that his usual place of residence was in Zone B.

End of example

Step 2

Write your zone or overseas forces tax offset amount at question T4 – label R in your tax return. Do not show cents. Go to question T5 Invalid and invalid carer 2023.

Category 2

Your usual place of residence was in more than one zone, or you:

  • served in a specified overseas locality for less than 183 days, or
  • served in a specified overseas locality and you served in one or more zones for a total of at least 183 days.

You claim for the number of days in each eligible place divided by 183, to a maximum of 183 days for a year. Start with your zone that has the highest fixed amount in Table 3. This will give you the greatest benefit.

Example 1: number of days in an eligible place

Your usual place of residence was in Zone A for 100 days and 120 days in Zone B. You would claim 100 ÷ 183 days for Zone A and 83 ÷ 183 days for Zone B.

End of example

 

Example 2: served in a specified overseas locality

You served 100 days in a specified overseas locality. You would claim 100 ÷ 183 days.

End of example

 

Example 3: overseas locality as a member of the defence forces and a zone

You served 100 days in an overseas locality as a member of the defence forces and served a further 83 days or more in a zone. You would claim the full overseas forces tax offset.

End of example

 

Example 4: served in an overseas locality and your usual place of residence

You served 100 days in an overseas locality and your usual place of residence was in a special area for 185 days. As the special area in Table 3 shows the highest fixed amount and you use up the maximum 183 days for this, you would simply claim the full special area amount and ignore the 100 days in an overseas locality.

End of example
