Smart Filing Advice for American Expats Moving to Australia: An Expat's Guide to Taxes

Moving to Australia is a big undertaking with much to organize—visas, health, housing, and perhaps even becoming a fan of Vegemite. But for US expats making the move, there's an added consideration: taxes.

Being in Australia doesn't get you off the hook from Uncle Sam. In fact, the US has one of the very few tax systems that makes its citizens file annual tax returns even if you're living overseas full-time. This will mean that as soon as you set Down Under, you'll probably have to file with the IRS and also the Australian Taxation Office (ATO).

This handbook analyzes smart tips to file smart as a US expat in Australia, defines common issues, and indicates how to remain compliant (without doubling up on tax).

The Problem: Two Tax Systems, One You Didn't See Coming

Quite a few Americans are surprised to find that they still need to file US taxes when abroad. Even if you're taxing in Australia, you still have to report your worldwide income to the IRS.

Meanwhile, most US expats are taxed as Australian residents, meaning you also have to lodge Australian tax returns on all worldwide earnings.

It can be a messy affair—particularly if you have no idea how the two systems overlap. Fortunately, the right strategy and some clever filing tips will keep you ahead of the game.

The Solution: Smart Filing Tips for Expats Filing Taxes in Australia

1. Know Your Filing Requirements Early

As a US citizen or Green Card holder, you'll need to file:

• Form 1040 annually with the IRS

• Other forms if you have foreign accounts or assets (see below)

In Australia, you'll usually need to lodge a return if:

• You receive income from employment, investment, or rental property

• You're an Australian resident for tax purposes

Knowing both systems early avoids hassle later—particularly if you're relocating mid-year.

2. Apply Tax Treaties and Credits to Prevent Double Taxation

The US and Australia have a tax treaty that prevents you from paying double tax on the same income. As a US expat, you have two principal tools:

• Foreign Earned Income Exclusion (FEIE)
  Exclude up to $126,500 USD (2025 estimate) of foreign-earned income on Form 2555.

• Foreign Tax Credit (FTC)
  Get a dollar-for-dollar credit for Australian tax paid on Form 1116.

Both choices will lower or zero out your US tax liability. It's up to a tax professional to determine the best option for you based on your situation and income.

3. Monitor Your Foreign Bank Accounts and Superannuation

US expats in Australia usually overlook foreign reporting requirements. If you have:

• Australian bank accounts

• A superannuation fund (super)

• Investment accounts

• Business interests

…you'll probably need to file:

• FBAR (FinCEN Form 114) – if your aggregate foreign accounts are more than $10,000 USD at any time during the year

• FATCA (Form 8938) – if your foreign financial assets are more than IRS thresholds

Even when no tax is payable, failing to file these forms will incur large penalties.

4. Beware of Superannuation Complications

Australian superannuation accounts are not handled the same way by the IRS as by the ATO. In the US:

• Employer contributions can be treated as taxable

• Investment gains within the fund could have to be reported each year

• You may be subject to PFIC rules if your super contains non-US mutual funds
   

This is one of the most confusing sections of US expat tax in Australia, so it's worthwhile getting professional assistance.

5. Don't Miss Filing Deadlines

Here's a brief summary of important deadlines:

Late filing—even if no tax is owed—can lead to penalties or jeopardize your compliance status.

Real-World Insight

"When I relocated to Sydney, I had no idea I was supposed to continue filing US taxes. I'd been contributing to my super and thought that paid for everything. Three years into it, I discovered that I should've been reporting those accounts—and it was overwhelming. Fortunately, the streamlined amnesty program allowed me to get back on track penalty-free."

People Also Ask (PAA)

1. Do US expats residing in Australia need to report US taxes?

Yes. US citizens and green card holders are required to report annual US tax returns regardless of where you reside.

2. Are US expats in Australia subject to double taxation?

Yes. Through the Foreign Earned Income Exclusion, Foreign Tax Credit, and the US-Australia tax treaty, you can prevent double taxation on the same income.

3. What are the forms expats must submit in Australia?

US expats are required to submit an Australian tax return if they're tax residents, as well as their US federal return, FBAR, and potentially FATCA disclosures.

Frequently Asked Questions

1. If I haven't filed US taxes while I've been in Australia, what will happen?

You might qualify for the IRS Streamlined Filing Compliance Procedures, which allow you to catch up penalty-free—if your non-filing was non-willful.

2. Is my Australian super fund subject to tax in the US?

It could be. The IRS doesn't consider Australian super to be a tax-deferred account. Contributions, income, and distributions may all have to be reported.

3. Should I hire a standard tax professional in Australia?

Not likely. Not many Australian tax agents are qualified in US tax law, and not many US CPAs know about superannuation or the ATO. Find someone who has experience in expat tax Australia services.

Final Thoughts

If you're an American moving to Australia, knowing your expat tax reporting requirements is crucial. Between the ATO and IRS, reporting can seem daunting—but with good guidance and the right systems in place, it's totally doable.

The best thing you can do? Be ahead of the game early. Stay on top, work with a cross-border tax expert, and maintain good records—so you're never surprised.
