Many Americans move to Australia expecting their US tax obligations to end once they leave the United States. Unfortunately, that’s not how the US tax system works.
The United States is one of the few countries that taxes its citizens and Green Card holders on their worldwide income, regardless of where they live. This means that even if you have lived in Australia for years, earn all your income there, and pay Australian taxes, you may still need to file a US tax return.
The good news is that many Americans in Australia can reduce or eliminate double taxation through various tax credits and exclusions. The challenge is understanding which rules apply to your situation and making sure all required forms are filed correctly.
Do I Have to File a US Tax Return If I Live in Australia?
Possibly.
If you are a US citizen or Green Card holder, you may need to file a US tax return if your income exceeds the IRS filing thresholds for your filing status.
Income that may need to be reported includes:
- Australian employment income
- Self-employment income
- Rental income
- Interest and dividends
- Capital gains
- Pension and retirement income
- Certain trust distributions
Even if you owe no US tax, filing requirements may still apply.
Will I Have to Pay Tax Twice?
Not necessarily.
Many Americans in Australia do not end up paying tax twice because of tax relief provisions available to US expats.
The two most common options are:
Foreign Tax Credit (FTC)
The Foreign Tax Credit allows you to claim credits for Australian taxes paid on income that is also taxable in the US.
Because Australian tax rates are often higher than US tax rates, many Americans find that the Foreign Tax Credit significantly reduces or eliminates their US tax liability.
Foreign Earned Income Exclusion (FEIE)
The Foreign Earned Income Exclusion allows eligible taxpayers to exclude a portion of foreign earned income from US taxation.
Depending on your circumstances, one option may provide a better result than the other.
What Other Forms Might I Need to File?
A US tax return is only part of the picture for many Americans living in Australia.
Additional reporting requirements may include:
FBAR (FinCEN Form 114)
You may need to file an FBAR if the total value of your foreign financial accounts exceeded US$10,000 at any point during the year.
Form 8938
Some taxpayers must report foreign financial assets under FATCA rules.
Form 3520 and Form 3520-A
These forms may be required for certain foreign trusts and other foreign financial arrangements.
Other International Reporting Forms
Depending on your situation, additional reporting may apply for:
- Foreign corporations
- Partnerships
- Trusts
- Investments
- Retirement arrangements
Penalties for failing to file these forms can be substantial, even when no tax is owed.
Why Is Filing US Taxes From Australia More Complicated?
Australia has several financial products and structures that often create additional US reporting challenges.
Common examples include:
- Australian superannuation
- Self-managed super funds (SMSFs)
- Family trusts
- Managed investment funds
- Australian companies
There is also a timing difference between the Australian and US tax years.
Australia generally operates on a 1 July to 30 June tax year, while the United States uses a calendar year from 1 January to 31 December. This can create additional complexity when reporting income.
Should I Use a Specialist US Expat Tax Firm?
For many Americans, the answer is yes.
While some taxpayers have relatively straightforward situations, others have multiple reporting obligations that can be difficult to navigate without specialist knowledge.
A US expat tax specialist may help with:
- Tax return preparation
- FBAR filings
- FATCA reporting
- Streamlined Tax Amnesty filings
- Foreign trust reporting
- Superannuation reporting
- Cross-border tax planning
