The Ultimate Tax Guide for Australian Expats in the US in 2025

Yes! You need a Social Security Number (SSN) to file your US tax return electronically. If you don’t have an SSN you can apply for an Individual Taxpayer Identification Number (ITIN).

If you’re an employee, you also need a Form W-2 to file your US tax return. Your US employer is required to send your W-2 by January 31. It shows your wage and salary details and the amount of taxes withheld from your paycheck for the calendar year. If you’re an independent contractor or self-employed, a Form 1099-MISC is used instead.

If you’re an E-3 visa holder, it’s a requirement that you’re employed with a salary or wage. So, for Australian expats with E-3 visas their employer income statement should only be in the form of a W-2 form.

If you receive income from other sources, such as interest, dividends, and capital gains, you’re issued Form 1099 income statements from financial institutions e.g., banks, stock brokerage accounts.

The specific IRS forms you need to file depend on your visa, your employment classification, and other factors.

Australian expats in the US are required to report foreign financial accounts through the Foreign Bank and Financial Accounts Report (FBAR). If you had a total of over US$10,000 aggregated across all your foreign accounts at any time during the tax year, you need to file an FBAR. Be aware, you must list all foreign accounts on your FBAR, even zero balance accounts. That’s because the overall total of your foreign accounts met the $10,000 threshold. And be sure to include all foreign accounts, not just bank accounts, such as stock portfolios, shares, and other assets. A common mistake expats make is to only list bank accounts or fail to list zero balance accounts. But it’s vitally important to prepare your FBAR correctly otherwise the IRS can impose severe penalties. Drop us a line if you need help preparing your FBAR.

You can file your US tax return yourself by downloading the IRS forms. Or you can file electronically using IRS software or commercial US tax preparation software such as Turbo Tax. There are also tax services such as a tax accountant or an Australian expat tax service to prepare and electronically file your US tax return.

At the Federal level, generally, No.

That’s because there’s a US-Australia Tax Treaty which means you’re able to leverage the tax paid to the ATO on your Federal return to offset what the IRS calculates. As Australia’s tax rates are typically higher than the IRS’s, this typically results in no additional US tax owing. But, you still need to declare Australian sources of income on your Australian tax return.

However, when it comes to State taxes, you might get taxed on Australian sourced income, depending on which US state you live in, including New York and California. That’s because at the state level, some US states don’t abide by the US-Australia Tax Treaty for assessing state taxes.

But you need to claim the IRS Foreign Tax Credit by filing Form 8833 and Form 1116 when submitting your US tax return. And also, you need to file an Australian tax return and include your Australian sourced income so that you can leverage credits for your US tax return.

Plus keep in mind, when it comes to State taxes, you might get taxed on Australian sourced income, depending on which US state you live in, including New York and California. That’s because at the state level, some US states don’t abide by the US-Australia Tax Treaty for allowing tax credits.
