Planning a Trip to Australia? Here’s How It Affects Your U.S. Taxes

July 17, 2025 BY

Planning a trip or move to Australia? Learn how U.S. tax rules apply to citizens abroad, including superannuation and IRS reporting.

Australia is among the most in-demand destinations for Americans looking for adventure, job opportunities, or a change of pace. Whether you are visiting for a short time or for the long term, something always falls through the cracks: your U.S. tax responsibilities don’t disappear when you travel overseas.

Why U.S. Taxes Follow You Abroad

As an American citizen or Green Card holder, you are taxed on your total income globally, no matter where you reside. That implies that if you make money in Australia—whether working locally, remotely, or through investments—you still need to file a U.S. tax return.

Most visitors think that since they’re paying taxes in Australia, they don’t have to report a thing to the IRS. Sadly, that’s not how it is.

Facts: U.S. Taxes, While in Australia

Requirement Applies to You?
File a U.S. federal tax return Yes, if your income exceeds the IRS filing threshold
Report foreign bank accounts (FBAR) Yes, if total balances exceed $10,000 USD
Report foreign assets (FATCA/Form 8938) Yes, if asset thresholds are met
Pay U.S. tax on foreign income Yes, unless excluded or credited


Even if you’re visiting or staying for a short time, your income from freelance work, investments, or living in Australia can offset these obligations.

How the U.S.-Australia Tax Treaty Can Assist

The U.S.-Australia Tax Treaty exists to assist in avoiding double taxation, when the same income is taxed twice, once in each country. However, this protection is not automatic. You’ll need to file the right forms and report the right exclusions or credits.

Important IRS Provisions That Assist:

  • Foreign Earned Income Exclusion (Form 2555): excludes up to ~$120,000 (annual indexed amount) of earned income if you qualify under residence or physical presence tests.
  • Foreign Tax Credit (Form 1116): Provides you a dollar-for-dollar credit for taxes withheld on income paid to the Australian Tax Office (ATO).
  • Totalization Agreement: Prevents you from paying into both the U.S. and Australian social security systems.

If you’re not certain which one applies or if you can claim both, your best bet is to meet with a company specializing in US expat tax in Australia.

Knowing Superannuation: The Pension Pitfall

Australia’s pension system, superannuation, is compulsory for the majority of employees. Though this contributes to your savings for down the line, it makes your U.S. tax life more complicated.

Here’s Why:

  • The IRS treats superannuation funds as foreign grantor trusts or foreign pensions, each with varying reporting requirements.

  • If your super balance exceeds certain amounts, you might be required to file Form 3520, 3520-A, and maybe Form 8938 (FATCA).
  • Properly failing to report your superannuation can result in significant penalties, even when no tax is due.

Note: In the U.S., you are not taxed on your employer’s super contributions until the money is paid out, but you must report it.

How to Proceed if You’re Visiting or Working in Australia

  1. Keep a Record of Your Days
    If you remain in Australia long enough to qualify as a tax resident, you’ll need to deal with tax systems in both nations. Travel logs can assist in determining eligibility for the Foreign Earned Income Exclusion.
  2. Open Bank Accounts Strategically
    If your foreign account balances are $10,000 or more at any time during the year, you’re required to file an FBAR. That means everyday checking accounts, superannuation, and even investment apps.
  3. Know Your Visa Status
    Your visa could influence your Australian tax residency—and subsequently, your qualification for IRS exclusions or credits. Visas that are employment-based generally mean you’ll pay taxes in the area.
  4. File Both Tax Returns
    You have to file:
  • Your Australian tax return (to the ATO)
  • Your U.S. tax return (to the IRS), even if all your income is foreign-earned
  • You might also need to file state taxes in the U.S., depending on your connection to your previous state of residence.

People Also Ask (PAA)

  1. Do I need to pay U.S. taxes if I reside or work in Australia?
    Yes. Green Card holders and American citizens have to report their worldwide earnings to the IRS, even though they are abroad.

  2. Can I prevent double taxation when in Australia?
    Yes. You can exclude or offset foreign tax on U.S. income previously taxed in Australia by claiming Foreign Tax Credit or Foreign Earned Income Exclusion.

  3. Is my Australian superannuation taxable in the U.S.?
    It varies based on your type of fund and contributions. You might not have to pay tax yet, but you will probably need to report it—and pay penalties if you don’t.

  4. What must I report as a U.S. citizen in Australia?
    At least:
  • Form 1040 (U.S. tax return)
  • Form 1116 or Form 2555 (to claim credit for double taxation)
  • FBAR (FinCEN 114) if account levels are exceeded
  • Form 8938 for foreign assets
    Form 3520/3520-A for superannuation (case-dependent)
  1. Do I need to report U.S. tax if I earned below $12,950?
    Perhaps not—but if you hold foreign accounts, investments, or are self-employed, you may still have reporting obligations.
  2. Do I file my U.S. taxes myself or need assistance?
    Technically, yes. But the majority of expats engage professional tax accountants due to the complexity of foreign income, superannuation, and FBAR/FATCA reporting.

Final Thoughts

Coming to or living in Australia as an American isn’t merely a matter of passports and airline tickets—it’s a matter of complying with two tax regimes simultaneously. With the proper approach, double taxation can be avoided and superannuation reporting achieved without penalty.
