Tax residency in Australia: how the day count works
Australia treats you as resident if you are present for 183 days or more in the income year, which runs 1 July to 30 June, unless your usual place of abode is outside Australia and you do not intend to take up residence. Part of a day counts as a whole day, and three other tests can make you resident on fewer days.
What is the day threshold in Australia?
183 days, measured inside the income year rather than the calendar year. Presence does not have to be continuous: every day you are physically in Australia between 1 July and 30 June is added to the same total, so a winter stay and a spring stay stack.
The test carries an escape hatch, and it is narrower than it looks. The 183-day rule does not apply if the Commissioner is satisfied of both of two things: that your usual place of abode is outside Australia, and that you have no intention of taking up residence in Australia. Both limbs must hold together. Someone who keeps a flat in London but is quietly deciding to stay in Sydney fails the second limb and is resident. The ATO's 183-day test page states the exception, and PwC's Australia summary gives the same wording.
| Day threshold | 183 days or more, continuous or intermittent |
|---|---|
| Counting window | Income year, 1 July to 30 June, not the calendar year |
| Partial days | Part of a day counts as a whole day, per Taxation Ruling TR 2023/1 |
| Other triggers | The resides test, the domicile test, and the Commonwealth superannuation test |
| Tax authority | Australian Taxation Office (ATO) |
| Return deadline | 31 October following the income year, later via a registered tax agent |

Calendar year or rolling window?
Neither. Australia uses a fixed twelve-month income year that starts on 1 July, the same structural quirk as the United Kingdom with its 6 April year, and it is the single most common error people make about Australian residency. A calendar-year total flatters you: a stay running from July to December sits in one income year and looks like half a calendar year, while a stay running from February to August splits across two income years and looks longer than it counts. Cut your travel history at 30 June, then count.
Do partial days count?
Yes, and the ATO says so plainly. Taxation Ruling TR 2023/1 records that presence in Australia for part of a day counts as a whole day, adopted for administrative ease. So a red-eye landing at 6am and a departure the following evening is two days, not one and a bit. Given the flight times involved, most people arriving in Australia gain a day at each end of every trip on this convention.
What else can make you resident besides days?
Three further tests, and passing any one of the four is enough. The resides test asks the ordinary-concepts question of whether you live in Australia, weighing your intention, family, business ties and assets, and it can make you resident on well under 183 days. The domicile test catches anyone whose domicile is Australian unless they have established a permanent place of abode outside it, which is why departing Australians often remain resident long after the plane leaves. The Commonwealth superannuation test covers certain federal public servants through their superannuation scheme membership.
The wording gap between the tests repays attention. The 183-day test lets you out on a usual place of abode overseas. The domicile test demands a permanent place of abode overseas. Permanent is the harder standard, and every residency dispute in Australia seems to turn on which phrase applies.
A worked example with 2026 dates
Safe on the calendar, resident on the income year
An engineer from Manchester takes a Sydney contract in the 2026 to 2027 income year and checks his numbers against the calendar year out of habit.
| Stay | Dates | Days |
|---|---|---|
| Sydney contract | 12 Jul to 20 Dec 2026 | 162 (20 + 31 + 30 + 31 + 30 + 20) |
| Return visit | 5 Feb to 1 Mar 2027 | 25 (24 + 1) |
| Calendar 2026 total | 162, comfortably under 183 | |
| Income year 2026 to 2027 total | 187 |
By calendar 2026 he is 21 days clear of the line. By the income year that actually applies he is at 187 and over it, so unless he can show both a usual place of abode in England and no intention of residing in Australia, he is an Australian resident for that year. Flying home on 15 December rather than 20 December would have put him at 182.
How do I track my days for Australia?
Keep the tally against the 1 July boundary, not 1 January, and count arrival and departure days in full. Remember that the day count is only one of four routes into Australian residency, so a clean 182 does not settle the question if your home and family have moved south with you.

Frequently asked questions
Does Australia use the calendar year for the 183-day test?
No. The Australian income year runs 1 July to 30 June, and the 183 days are counted inside it. A calendar-year total is the wrong number, and it is usually the wrong number in your favour, which is what makes the mistake dangerous. Split your travel at 30 June and count each income year separately.
Can I pass 183 days and still not be an Australian resident?
Yes, but only on a narrow exception. The 183-day test does not apply if the Commissioner is satisfied of two things at once: that your usual place of abode is outside Australia, and that you have no intention of taking up residence here. Both limbs have to hold. Fail either one and 183 days makes you resident.
What is the difference between usual place of abode and permanent place of abode?
They belong to different tests and the wording is deliberately not the same. The 183-day test uses usual place of abode, meaning the place you normally live. The domicile test uses permanent place of abode, a higher bar. So the escape route from the 183-day test is easier to satisfy than the one from the domicile test, and quoting the wrong phrase to the ATO gets you nowhere.
Do all four Australian residency tests have to be met?
No, any single one is enough. There are four: the resides test based on ordinary concepts, the domicile test, the 183-day test, and the Commonwealth superannuation test for certain federal public servants. Satisfying one makes you a resident for tax purposes even if the other three point the other way.
When does the Australian tax year run?
1 July to 30 June, which the Australian Taxation Office calls the income year. The individual return is due by 31 October following the end of the income year, with later dates available where you lodge through a registered tax agent. The 2026 to 2027 income year therefore ends on 30 June 2027 and is due on 31 October 2027.
Do partial days count in Australia?
Yes. Taxation Ruling TR 2023/1 states that presence in Australia for part of a day counts as a whole day, for administrative ease. Arrival and departure days both go on the tally, and your presence does not need to be continuous: all the days you are physically in Australia during the income year are added together.
Which authority decides Australian tax residency?
The Australian Taxation Office, the ATO. It applies the four statutory tests, sets out its position in Taxation Ruling TR 2023/1, and issues the assessment. The Department of Home Affairs handles visas, and a working holiday or skilled visa neither creates nor prevents Australian tax residence.
