Australian tax residency rules for US expats
Under Australian tax residency rules, your residency status determines how you’re taxed, whether only on Australian-sourced income or your worldwide income.
Australian tax residency rules can be a critical consideration for US expats. These rules impact your tax responsibilities in both Australia and the US. This guide explains how the ATO defines “residency”. It also shows you how to avoid double taxation and remain compliant in both countries.
What is tax residency in Australia?
In Australia, your tax residency status determines whether the Australian Tax Office (ATO) treats you as a resident for tax purposes, impacting how and where your income is taxed.
To determine your tax residency, the ATO looks at several key factors, including:
- Your physical presence in Australia
- Whether you have a home in Australia
- Your employment status and location
- Family and social ties
These factors come in the form of residency tests that the ATO uses to determine your tax residency status.
📌 Tip: The ATO considers all factors together, so no single factor decides your residency status. Make sure to assess your full situation before assuming how you’ll be classified.
The four residency tests
The ATO uses four main tests to determine whether an individual is a tax resident of Australia. Meeting just one of these tests can be enough for the ATO to consider you a resident.
Here’s a breakdown of each test:
-
The resides test:
-
This is the primary test. In it, the ATO examines your behavior, habits, and ties to Australia, such as where your home, family, and work are based.
-
-
The ATO domicile test
- If you don’t pass the “resides” test, the ATO checks whether Australia is your domicile (your permanent legal home). Even if you’re living abroad temporarily, you’ll generally be treated as a resident under the domicile test.
-
The ATO 183-day test
- This test is based on how long you’re physically present in Australia. If you spend 183 days or more in Australia during the tax year, you’ll typically be treated as a tax resident under this test (even if you don’t intend to live there permanently).
-
The commonwealth superannuation test
- This test applies only to Australian government employees working overseas who are members of certain superannuation schemes (like CSS or PSS). If you qualify, you’re automatically considered a tax resident, regardless of where you live.
Here’s a quick summary in table form to help compare the four tests side by side:
|

📌 Note: While one test is sufficient to be considered a tax resident, multiple tests are sometimes assessed simultaneously for a more accurate outcome.

Why tax residency matters for US expats
If the ATO considers you a tax resident, then you will be taxed on all your worldwide income (including income from the US).
For US expats, this is important because:
- You may have to file and pay tax in Australia and the US.
- Your US Social Security, pensions, or investment income is taxable in Australia.
- Tax residency determines your eligibility for certain deductions, offsets, and tax treaty benefits.
- Incorrect residency classification can lead to underpayment, penalties, or double taxation.
This can be the perfect opportunity to take advantage of any available tax relief under the US-Australia tax treaty.
📌 Bottom line: Your residency status decides where you report income and how much tax you pay. Getting it wrong could cost you.
Does the US-Australia tax treaty affect Australian tax residency rules?
No, the US-Australia tax treaty does not change how the ATO determines tax residency. The ATO uses its own rules and tests to assess whether you are a tax resident of Australia. But the treaty does help relieve you of double taxation if you’re considered a resident of both countries.
Can I be a tax resident of both Australia and the US?
Yes. This is known as dual tax residency, and it can happen if you meet the tax residency requirements in both countries. In such cases, the treaty includes “tie-breaker rules” to decide which country has primary taxing rights.
If you’re a dual tax resident, the treaty looks at:
- Where you have a permanent home
- Where your personal and economic ties are stronger
- Where you live most of the time
- Your nationality
These tie-breaker criteria help determine which country gets the final say on your tax residency for treaty purposes. This ensures that you’re not taxed twice on the same income.
Do I need to file tax returns in both countries?
Yes, you do. The US operates on a citizenship-based taxation system, while Australia uses a residency-based system.
This means that if you are a US citizen or a green card holder in Australia, you’ll need to file a US tax return and an Australian tax return if you’re considered a resident for tax purposes.
What documents should I keep as proof of residency?
To support your claim as a tax resident of Australia, or to prove you are not a resident, it’s important to keep documentation that reflects your ties to the country.
Here are common documents to keep as proof of residency:
- Lease or rental agreements
- Utility bills in your name
- Bank statements with a local address
- Employment contracts
- Visa details or immigration status
- Passport entry/exit stamps
📌 Tip: Keep physical and digital copies, and save everything for at least five years.
FAQs
-
What makes me a tax resident in Australia?
You’re considered a tax resident of Australia if the ATO determines that you live in Australia as part of your regular lifestyle. This includes factors like your physical presence, whether you have a home in Australia, where your family and work are based, and your long-term intentions.
Even if you live overseas part of the year, having strong personal, economic, or residential ties to Australia may still make you a resident for tax purposes.
