Americans living in Australia face a unique set of tax responsibilities. Even after establishing residency overseas, US citizens generally remain subject to US tax filing requirements, including reporting worldwide income and certain foreign financial assets.
For the 2027 filing season, Americans in Australia may need to report employment income, investments, rental properties, superannuation, and foreign business interests. Understanding how US and Australian tax rules interact can make preparing a return more complicated than a typical domestic filing.
Fortunately, several firms specialize in US expatriate taxation and provide services remotely to Americans living abroad.
Here are five best US expat tax firms worth considering in 2027, each offering different services and approaches to international tax preparation.

What Should Americans in Australia Look for in a US Tax Firm?

- Personalized support: Some firms provide dedicated accountants, while others use online platforms or software-assisted preparation. The preferred approach depends on the taxpayer’s needs.
- Scope of services: Individuals with foreign corporations, investments, or overdue returns should confirm that their provider handles the required international forms.
- Transparent communication: Understanding the preparation process, expected turnaround, and available support can make the filing experience more manageable.
Preparing for the 2027 US Tax Filing Season
Americans living in Australia generally need to file US tax returns when their income meets the applicable filing thresholds.
For the 2026 tax year, filed in 2027, important considerations include the Foreign Tax Credit, Foreign Earned Income Exclusion, FBAR, FATCA, and potentially additional foreign investment or business reporting.
Qualifying Americans abroad generally receive an automatic extension until June 15, 2027, to file their federal returns. However, any federal income tax owed is generally due by April 15, 2027, to avoid interest.
Preparing Australian income statements, tax assessments, investment records, and foreign account information early can help simplify the filing process.
