Zone Tax Offset Calculator — Remote Area Tax Rebate

What Is the Zone Tax Offset?

The zone tax offset (ZTO) is a non-refundable tax offset for Australian residents whose usual place of residence is in a remote or isolated area for 183 days or more in an income year. The ATO classifies eligible locations as Zone A or Zone B, with special areas designated inside either zone.

The offset exists to recognise the higher cost of living, isolation and other factors that come with living in these areas. It does not apply to an offshore oil or gas rig.

Because the ZTO is non-refundable, it reduces your tax liability to a minimum of zero but does not generate a refund on its own. Use our income tax calculator to see how it sits against your marginal rate, and the Low Income Tax Offset (LITO) guide for the other offset most remote workers claim.

How Much Is the Zone Tax Offset?

The offset has two parts: a fixed amount set by your zone, and a percentage of your base amount if you maintained dependants. The maximum with no dependants is $1,173, for a special area.

A special area replaces the Zone A or Zone B fixed amount — it is not added to it. A resident of a special area within Zone A claims $1,173, not $338 plus $1,173.

The base amount

You only have a base amount if you maintained a dependent child or student, had sole care of one, or were entitled to the invalid and invalid carer tax offset. The components are:

• $376 for each full-time student under 25
• $376 for the oldest non-student child under 21, and $282 for each other child under 21
• $1,607 if you had sole care for the whole year ($4.40 a day for part of a year)
• The invalid and invalid carer tax offset you claim at question T5, up to $3,396

Add those together, then apply your zone’s percentage. A Zone A resident with one student dependant claims $338 + 50% of $376 = $526. The same person in Zone B claims $57 + 20% = $132.20.

A dependant’s base amount reduces by $1 for every $4 of their adjusted taxable income over $282. If their income is under $286 you claim the base amount in full.

Who Is Eligible for the Zone Tax Offset?

Eligibility rests on your usual place of residence, not where you work. To claim, your usual place of residence must have been in a zone for 183 days or more during the income year. The days need not be consecutive.

• Your usual place of residence was in a Zone A, Zone B or special area location
• That was true for 183 days or more between 1 July and 30 June
• You received assessable income that you pay tax on, and you lodge a tax return

If you were there fewer than 183 days

You may still qualify. If your residence in the zone was a continuous period of less than 5 years, you can carry forward unused days from the first year, provided:

• you could not claim in that first year because you lived there fewer than 183 days
• the first year’s days plus the current year’s days total 183 or more
• the current-year period includes the first day of the income year

The ATO’s own example: a taxpayer living in a remote area from 1 March 2021 to 30 September 2025 could not claim in the first year (122 days), but added those 122 days to the 92 days from 1 July to 30 September 2025 for a total of 214 — enough to claim.

Non-residents for tax purposes are not eligible — see our non-resident tax guide.

How Do You Claim the Zone Tax Offset?

You claim it at question T4 Zone or overseas forces, label R, in the supplementary section of your individual tax return.

1. Confirm your zone — check your location on the ATO’s Australian zone list. The list is not exhaustive; some locations qualify as special areas without appearing on it.
2. Count your days — the number of days between 1 July and 30 June your usual place of residence was in the zone.
3. Work out any base amount — dependants, sole care, invalid and invalid carer offset.
4. Subtract any remote area allowance you received from Centrelink or the Department of Veterans’ Affairs.
5. Lodge — by 31 October if you self-lodge, or by your tax agent’s extended date.

Your employer does not apply the offset through PAYG withholding during the year, so you receive it as a reduced assessment or larger refund when you lodge.

If you qualify for both a zone tax offset and an overseas forces tax offset, you can claim only one — take whichever is greater.

What If You Lived in More Than One Zone?

The offset is apportioned in this case. If one zone accounted for 183 days or more and it has the highest fixed amount of the places involved, you claim that zone in full and ignore the rest. Otherwise you claim each location as a fraction of 183 days, starting with the zone that pays most, and capping the total at 183 days.

The ATO’s worked examples make the two paths concrete:

• Zone A for 190 days, Zone B for 40 days. Zone A pays more and already exceeds 183 days, so the claim is the full Zone A amount of $338. The Zone B time is ignored.
• Zone A for 100 days, Zone B for 120 days. Neither reaches 183. The claim is 100/183 of the Zone A amount plus 83/183 of the Zone B amount — the Zone B days are trimmed so the total stops at 183.

The calculator above handles both. Tick “I also lived in a second zone” and it selects the correct ATO worksheet for you.

How Does the Zone Tax Offset Affect Take-Home Pay?

The offset reduces the tax you owe at assessment time. On a $85,000 salary, a special area resident pays $1,173 less tax than an identical taxpayer in a capital city.

Worked example: $85,000 in a special area

That is roughly $45 a fortnight. Because the offset is a flat amount rather than a percentage, it is worth proportionally more at lower incomes. Model your own salary with our take-home pay calculator.

Can FIFO Workers Claim the Zone Tax Offset?

Fly-in fly-out workers cannot claim the zone tax offset unless their usual place of residence is itself in a zone. The ATO is explicit: “You’re not eligible if you work in a qualifying remote or isolated area but don’t live there.”

The indicators the ATO weighs are where your family lives, where you are enrolled to vote, where your belongings are, and where you return after a roster. See our mining and FIFO pay guide for the deductions FIFO workers can claim.

Which Towns Are in Each Zone?

Zone boundaries are defined in tax law and published by the ATO as a per-state list of locations. A special area is one more than 250 km, by the shortest practicable surface route, from the nearest population centre of 2,500 or more people.

The zone list changed on 1 July 2026. Locations widely described elsewhere as Zone B — including Darwin, Palmerston and Humpty Doo — are now listed as Zone A. Always check the current ATO list rather than an older summary.

There are no zone locations in the Australian Capital Territory or Victoria. For every other state, check the ATO list directly: New South Wales, Northern Territory, Queensland, South Australia, Tasmania and Western Australia.

How Does the Zone Tax Offset Interact with Other Offsets?

The zone tax offset stacks with other non-refundable offsets, including the Low Income Tax Offset. Together they reduce your tax payable, but never below zero — any excess is lost rather than refunded or carried forward.

Two interactions are worth knowing. A remote area allowance from Centrelink or DVA reduces your zone offset dollar for dollar. And the zone tax offset itself is not assessable income for Centrelink purposes, so claiming it does not affect your payments.

You cannot claim both the zone tax offset and the overseas forces tax offset — if you qualify for both, claim the larger.

What Records Do You Need?

You must be able to show your usual place of residence was in the zone for the days you claim. The ATO does not want documents with your return, but you must produce them if asked.

• Property records — lease, mortgage statement or council rates notice at the zone address
• Utility bills — electricity, water, gas or internet at that address
• Electoral enrolment and vehicle registration showing the zone address
• School enrolment for children at a zone-area school

You will also need the adjusted taxable income of any dependent children or students, and the amount of any remote area allowance. Keep records for five years from lodgement. Our payslip guide explains which fields to check.
