Spend Months Overseas? The ATO Has Your Travel Dates — But 183 Days Is Not the Whole Story
Australian tax residency explained in plain English for people and family-business owners moving between countries
Written by: Melissa Cunliffe (CA)
If you spend more than half the year overseas, you automatically stop being an Australian tax resident — right? Not necessarily.
The ATO has renewed its passenger-movements data-matching arrangements with the Department of Home Affairs for 2026–27 through to 2028–29. Information can include arrival and departure dates, passport details and visa or status information.
Travel days are evidence. They are not, by themselves, the whole Australian tax-residency test.

Why the ATO uses travel information
Passenger-movement information can help the ATO identify cases where a person’s reported residency position may not align with their actual travel pattern. The data is an indicator used alongside other information.
This matters because residency determines the scope of Australian taxation and can affect foreign income, investments, capital gains and other tax outcomes.
The 183-day myth
There is a statutory 183-day test, but it is only one of Australia’s residency tests and it contains more detail than simply counting calendar days. Other residency tests can apply depending on the facts.
A person can spend substantial time overseas and still remain an Australian resident for tax purposes. Conversely, someone spending time in Australia may not necessarily be resident merely because a day count is reached. The full circumstances matter.
What sorts of facts matter?
Residency analysis can consider factors such as:
Where the person ordinarily lives.
Where their spouse or family lives.
Whether they established a real home overseas.
The nature and duration of employment overseas.
Australian and overseas assets.
Social and economic ties.
The pattern and purpose of travel.
Intention and behaviour before, during and after the move.
No single factor should be treated as an automatic answer in every case.
Why residency can have a big tax impact
Australian residents are generally taxed on worldwide income, subject to the detailed rules and relief such as foreign tax offsets. Foreign residents are generally taxed differently, with Australian-source income and specific CGT rules becoming particularly important.
Residency can therefore affect salary, foreign business income, overseas investments, shares, trusts, property and capital gains. For business owners, the consequences can extend into how they manage Australian companies and trusts while living overseas.
Do not wait until a sale to ask the residency question
Residency becomes especially important when a major transaction occurs — for example, selling property or investments. Trying to determine a person’s residency retrospectively after the transaction can be much harder than documenting the position when the move happens.
Where a person is planning to relocate, obtain advice before major transactions and before making assumptions about the tax treatment of existing assets.
Keep evidence while it is easy to obtain
Years later, it can be surprisingly difficult to reconstruct where someone lived, what accommodation was available, what their intentions were or when family members moved.
Travel records and calendars.
Employment contracts and work location.
Lease or home purchase documents overseas.
Australian accommodation retained or disposed of.
Family relocation details.
Visa and immigration documents.
Utility, banking and other evidence of living arrangements.
An example
Suppose an Australian business owner accepts a two-year role overseas. They spend fewer than 183 days in Australia, but their spouse and children remain in the family home, they return regularly, keep substantial Australian assets and never establish a settled home overseas.
The day count is relevant, but it cannot sensibly answer the residency question on its own. The broader facts need to be considered.
A practical pre-departure review
Clarify how long you expect to be overseas and why.
Identify where your home and family will be located.
Review employment and business-management arrangements.
List Australian and foreign assets.
Identify major transactions planned before or during the move.
Document the facts and obtain residency advice early.
Revisit the position if the move becomes longer, shorter or materially different from the original plan.
The educational takeaway
ATO access to passenger-movement data should not be viewed as a substitute for the legal residency tests. It simply means travel patterns are increasingly easy for the ATO to verify. The taxpayer’s position still needs to be supported by the full facts.

PROTECT
Protect against unexpected worldwide-income or CGT outcomes by establishing the residency position early and documenting the facts contemporaneously.
PROSPER
Structure international opportunities around the future the person actually wants, with the tax position understood rather than discovered after the event.
