ATO

If you are physically present in Australia for 183 days or more during a financial year (1 July to 30 June), the Australian Taxation Office's 183-day test can treat you as an Australian tax resident for that year. Residency generally means Australia can tax your worldwide income. To stay outside this particular test, keep your total days in Australia below 183 — but note it is only one of several tests, any of which can make you a resident.

Who it applies to

This matters most if you are:

• A remote worker, digital nomad, or frequent traveler spending long stretches in Australia.
• Someone visiting on a working-holiday, student, or long-stay visa who loses track of cumulative days.
• An expat arriving in or leaving Australia mid-year, where days straddle the 1 July financial-year line.

It applies to individuals regardless of nationality — residency here is about physical presence and your living arrangements, not citizenship or the type of visa you hold.

The rule — and why it exists

The 183-day test is one of the statutory tests the ATO uses to decide tax residency. In broad terms, you meet it when both of the following are true in a financial year:

• Presence. You are physically in Australia for 183 days or more, whether continuously or in broken periods across the year.
• Usual abode and intention. Your usual place of abode is not outside Australia, or you intend to take up residence here. If your usual home is genuinely abroad and you don't intend to reside, the test can fail even past 183 days.

Why it exists: countries use time spent and where your usual home sits as proxies for where your economic life really is. The day count gives a clear, measurable threshold, while the abode-and-intention limb stops a mere long holiday from automatically making a genuine non-resident a taxpayer.

Counting the days

1. 1Add up every day you are physically present in Australia during the financial year (1 July to 30 June).
2. 2Days do not need to be continuous — they can be spread across multiple visits within the same financial year.
3. 3Any day of presence generally counts, including partial arrival and departure days.
4. 4The tally resets to zero at the start of each new financial year on 1 July; it is not a rolling 12-month window.
5. 5Reaching 183 days meets the day-count part of the test — the usual-abode and intention questions still apply.

Examples

Example 1 — clearly resident by days

You come to Australia in August and stay until May, spending about 270 days here in the financial year, with no settled home overseas. You pass the 183-day test and are treated as an Australian tax resident, so Australia can tax your worldwide income for that year.

Example 2 — over 183 days but usual home abroad

You keep a permanent home and family base in another country but spend around 190 days in Australia on a drawn-out work assignment, always intending to return. Although you exceed 183 days, the test may not be satisfied because your usual place of abode remains outside Australia and you do not intend to reside here.

Example 3 — days split across the financial year

You spend 120 days in Australia from April to June, then a further 100 days from July onward. Because the count resets on 1 July, neither financial year reaches 183 days on its own — even though the two stays add up to more than 183 across the calendar boundary.

Exceptions & edge cases

• The other residency tests. You can be resident with fewer than 183 days under the ordinary concepts (resides) test, the domicile and permanent-place-of-abode test, or the Commonwealth superannuation test — each applies independently.
• Double-tax agreements. If you are resident in two countries, the relevant treaty tie-breaker (permanent home → centre of vital interests → habitual abode → nationality) assigns a single treaty residence and divides taxing rights.
• Domicile can override the day count. If your domicile is in Australia, you can be resident unless the ATO is satisfied your permanent place of abode is overseas — regardless of how few days you spend here.

Common misconceptions

• "Under 183 days means I'm safe." False — the other tests can make you a resident with far fewer days.
• "Hitting 183 days makes me a resident automatically." Not quite — the test also asks whether your usual abode is abroad and whether you intend to reside here.
• "It follows the calendar year." No — the count runs over the financial year, 1 July to 30 June, and resets each 1 July.
• "Only Australian income is taxed." Residents are generally taxed on their worldwide income, subject to any applicable treaty relief.
