This is a comprehensive tax guide for U.S. expatriates in Australia, which details who must file taxes, what to report, key deadlines, and also which mistakes to avoid.

Do U.S. Expats in Australia Have to File U.S. Taxes?

As a U.S. citizen or green card holder who is a resident in Australia, you are to:

Report to the IRS if income criteria are met.
Report worldwide income
Report foreign financial accounts and assets.

Even should you pay no U.S. tax as an Australian taxpayer, filing is still required.

Key U.S. Tax Deadlines for Americans in Australia

For the past year’s income, the standard deadlines are:.

April 15th: Tax due date for the U.S.
June 15 Extension for US citizens living abroad.
15 if an extension is requested.

While expatriates get an automatic extension to June 15, interest on any due tax starts after April 15.

What Income Must Be Reported to the IRS

U.S. expatriates in Australia must report total world income, which includes:

Australian employment income
Self-employment or contract income
Rental income
Dividends and interest
Capital gains from shares or property
Cryptocurrency transactions
Foreign pensions and superannuation-related income

All income is to be reported in U.S. dollars, at appropriate exchange rates.

How the U.S. and Australian Tax Systems Interact

Australia taxes residents, which is different from the U.S., which taxes citizens. This difference may lead to double reporting, but not always to double taxation.

Australia and the U.S. have a tax agreement, which is to reduce conflicts, but the treaty does not do away with filing requirements.

Common Tax Relief Options for U.S. Expats in Australia

In the U.S., most U.S. expats in Australia are covered by the following.

Foreign Earned Income Exclusion (FEIE)

The FEIE, which for qualifying expats allows them to report less of their foreign-earned income if they meet either of the following:.

The Physical Presence Test, or
The Bona Fide Residence Test

This applies to earned income only, not investment income.

Foreign Tax Credit (FTC)

The Foreign Tax Credit is available for taxpayers to apply foreign tax paid in Australia against their U.S. tax. Also, because the tax rates in Australia usually are higher than what is applied in the U.S., many expats use the FTC to reduce or eliminate U.S. tax liability.

Superannuation and U.S. Tax Reporting

Australian superannuation is an area that mostly has U.S. expats confused.

From a U.S. tax perspective: From the tax standpoint in the U.S.

Superannuation does not automatically qualify as a tax-deferred retirement account.
Employer and individual contributions may present reporting issues.
Super funds may trigger FBAR and FATCA reporting.
In some cases earnings in super are taxable.

Superannuation reporting varies based on individual situations and account structure.

FBAR and FATCA Requirements in Australia

Many U.S. expats in Australia must file additional reporting forms.

FBAR (FinCEN Form 114)

Required should the total balance in foreign financial accounts exceed $10,000 at any time during the year.

FATCA (Form 8938)

Required when foreign financial assets exceed certain thresholds.

These are separate from your tax return. For that which you do not turn in on time, penalties may apply even if you don’t owe any tax.

Common Mistakes U.S. Expats in Australia Make

Tax professionals often report that they come across issues like

Assuming Australian taxes replace U.S. taxes
Forgetting FBAR or FATCA filings
Misreporting superannuation
Ignoring capital gains or crypto activity
