The Complete Tax Guide for US Expats in Australia

Updated: Feb 1

In today's increasingly interconnected world, a growing number of US citizens are opting to establish their lives in foreign countries, with Australia emerging as a sought-after destination. Amidst the excitement of relocating to the Land Down Under, it becomes imperative for American expatriates to have a solid understanding of their tax obligations. Navigating two tax systems can be challenging, but in this comprehensive guide, we explore US taxes for US citizens in Australia.

A Land of Advantages and Opportunities

Australia, situated in the southern hemisphere, boasts a myriad of benefits for those seeking a new place to call home. From its breathtaking landscapes to its thriving cities, this island continent offers a high standard of living and abundant prospects. With a strong economy, excellent healthcare system, and top-tier education, Australia presents a favorable environment for individuals and families alike. Additionally, its inclusive society, pristine beaches, and awe-inspiring natural wonders make it an ideal destination for nature enthusiasts and those who appreciate outdoor pursuits. Whether it's the relaxed lifestyle, cultural diversity, or strong sense of community, living in Australia offers a unique combination of advantages that contribute to a gratifying and rewarding experience.

Tax Filing Obligations in Australia

Australian tax residents are mandated to file a tax return if their annual income surpasses the filing threshold. When filing as a resident, the requirement involves reporting worldwide income, encompassing both Australian and non-Australian sources.

For non-residents, the requirement to file a tax return arises if they have any income originating from Australian sources, regardless of the amount. Non-residents are subject to higher tax rates compared to residents. However, non-residents are solely obligated to report income derived from Australian sources and are not required to disclose their worldwide income.

Australia Taxes vs U.S.

Australia is known for its higher tax rates when compared to the United States. In Australia, individuals in the highest income bracket can face tax rates up to 45%. In contrast, the United States has a maximum tax rate of 37% for its highest earners. To provide a clearer comparison, the table below summarizes the Australian tax brackets and indicates the corresponding U.S. tax rates applied to the maximum amount of each Australian bracket.

Australian Income Bracket (AUD)

Australia Tax Rate (%)

U.S. Tax Rate (%)*

Up to $18,200



$18,201 - $45,000



$45,001 - $120,000



$120,001 - $180,000



$180,001 and over



*The U.S. tax rates in this comparison are applied to the maximum amounts of the corresponding Australian tax brackets. Since the U.S. levies taxes in USD, we have used an assumed exchange rate of 1.50 AUD to 1 USD.

Australian Tax Residency

Determining tax residency in Australia is a critical factor in understanding one's tax obligations. While the determination process can be intricate and depends on individual circumstances, there are general guidelines to identify who qualifies as a tax resident:

  1. Residency Tests: Australia utilizes residency tests to determine tax residency. These tests include the "resides test" and the "domicile test."

  • Resides Test: This test considers an individual a tax resident if they reside in Australia and have established a home or significant ties to the country, considering factors like family, employment, and social connections.

  • Domicile Test: The domicile test applies to individuals who are not residents under the resides test. It considers an individual's permanent place of abode and their intention to reside in Australia indefinitely.

  1. 183-Day Test: Additionally, there is a 183-day test for temporary residents. If an individual spends 183 days or more in Australia during a financial year, they are generally considered tax residents.

  2. Double Taxation Agreements: Australia has double taxation agreements with several countries to address potential dual tax residency situations. These agreements can impact an individual's tax residency status.

It is crucial to understand that tax residency status has significant implications for tax obligations, including the taxation of worldwide income or solely income sourced from Australia. Determining tax residency should be approached diligently, considering individual circumstances, and seeking guidance from professionals or the Australian Taxation Office (ATO) to ensure accurate assessment and compliance with tax laws in Australia.

US-Australian Tax Treaty

The tax treaty between the United States and Australia offers significant benefits to U.S. expatriates who have chosen to reside in Australia. This treaty plays a vital role in preventing double taxation, a potential concern for expats. By eliminating the risk of being taxed on the same income by both countries, the treaty provides relief and ensures a fair taxation process.

US Tax Advantages Available for US Expats

U.S. expats residing in Australia have access to several tax benefits that can significantly impact their tax situation. One notable advantage is the Foreign Earned Income Exclusion (FEIE), which allows eligible expats to exclude a portion of their foreign earned income from U.S. federal income tax. This exclusion serves to alleviate the overall tax burden for expats earning income in Australia. Additionally, the Foreign Tax Credit (FTC) enables expats to offset their U.S. tax liability by claiming a credit for taxes paid to the Australian government. This provision ensures that expats are not subjected to double taxation on the same income. Moreover, expats may be eligible to contribute to retirement accounts such as Individual Retirement Accounts (IRAs) and take advantage of deductions and credits related to education expenses and healthcare coverage. Properly understanding and utilizing these tax benefits requires careful consideration, and seeking advice from a qualified tax professional is strongly advised to ensure compliance with both U.S. and Australian tax laws while maximizing available advantages.
