Physical Presence Test
Australia's distance from the US makes the 330-day test straightforward unless you travel frequently. The Australian financial year runs July 1 to June 30, which does not align with the US tax year and complicates FTC calculations.
Bona Fide Residence Test
An Australian permanent resident visa, a valid work visa (such as the 482 or 494), and registration with the ATO (Australian Taxation Office) with a TFN (Tax File Number) strongly support bona fide residence.
Common Visa Types:
Australia Tax System

Banking & FBAR in Australia
Major Banks (AUD)
FBAR Reminder
All Australian bank accounts, superannuation balances, and investment accounts must be reported on FBAR if aggregate balances exceed $10,000. Superannuation funds are particularly important - these are often high-value accounts that must be reported.
FATCA Compliance
Australia signed a Model 1 IGA with the US in 2014. Australian banks and financial institutions report US person data to the ATO, which shares with the IRS. Australian banks generally accept US citizens with standard FATCA documentation.
Common Pitfalls for Americans in Australia
Australian superannuation is taxed as a foreign trust by the IRS, requiring complex Forms 3520/3520-A annually
Mismatched tax years (Australia: July-June, US: January-December) complicate Foreign Tax Credit calculations
Australian franking credits (dividend imputation) have no US equivalent and create FTC complications
Australian Working Holiday Visa holders face a flat 15% tax from the first dollar, which may not match treaty provisions
Employer superannuation contributions (Superannuation Guarantee) are taxable income for US purposes

vs. US
Comparable to or slightly higher than major US cities
Notes
Sydney and Melbourne are among the world's most expensive cities for housing. Brisbane, Perth, and Adelaide offer lower costs. Regional areas are significantly cheaper. Medicare provides public healthcare, but private health insurance is common and incentivized.
FAQ: US Taxes in Australia
How is Australian superannuation taxed for US expats?
Australian superannuation is a major compliance issue. The IRS treats super funds as foreign trusts, potentially requiring Forms 3520 and 3520-A. Employer contributions to super are taxable income for US purposes (even though they are tax-advantaged in Australia). You must also report super balances on FBAR and potentially FATCA Form 8938.
What are Australian franking credits and how do they affect my US taxes?
Franking credits (dividend imputation credits) represent tax already paid at the corporate level on dividends. The US has no equivalent system. For FTC purposes, you may be able to claim the underlying corporate tax as a credit, but the mechanics are complex. Consult a cross-border tax professional.
How do I handle the different US and Australian tax years?
Australia's tax year runs July 1 to June 30, while the US uses January to December. For Foreign Tax Credits, you must allocate Australian taxes to the correct US tax year. This often requires splitting Australian tax assessments across two US tax years. Detailed records are essential.
Is the FEIE or FTC better for Americans in Australia?
Australia's tax rates (up to 45% plus 2% Medicare levy) are generally high enough that the Foreign Tax Credit provides more benefit. Australian taxes typically exceed US taxes, generating carryover credits. However, the mismatched tax years and franking credit complications require careful analysis.
How does the US-Australia totalization agreement work?
The agreement coordinates Social Security between the two countries. Temporary US workers in Australia (up to 5 years) stay on US Social Security. Locally employed workers are covered by Australia's system. Notably, Australia's Age Pension is means-tested and residency-based, not contribution-based, creating unique interactions with the totalization agreement.
