Your 2026 Compliance Checklist

Every form, threshold, and deadline a US expat in Australia needs to track this year. Bookmark this page and review it each January, and again each June 30 when your Australian financial year closes.

1. Confirm Your Filing Requirement

File Form 1040 if worldwide gross income exceeds roughly $14,600 ($400 if self-employed), regardless of Australian tax already paid.

2. Decide FEIE or FTC, and Don't Default

Model both. For most salaried Australian residents, the Foreign Tax Credit (Form 1116) beats the FEIE once your effective Australian rate exceeds US rates on the same income.

3. File FBAR If You Cross $10,000 (FinCEN Form 114)

Aggregate all foreign accounts, checking, savings, and superannuation. Your super balance almost certainly counts. File by April 15 (automatic extension to October 15).

4. Check FATCA Reporting (Form 8938)

Applies at higher thresholds than FBAR, generally $200,000+ in specified foreign assets for single filers abroad ($400,000+ married filing jointly). Super and Australian property investment count.

5. Classify Your Superannuation Fund

Determine industry/retail fund versus SMSF. This decides whether you need Forms 3520, 3520-A, and 8621 for any PFICs held inside the fund.

6. Audit for PFIC Exposure

Review any Australian managed funds, whether held personally or inside super, for PFIC classification. Consult a specialist if found, the reporting burden compounds annually.

Expert Guidance

When to Consult a Specialist

  • More than three items apply to youOnce several of these items overlap, a coordinated plan beats handling each in isolation.
  • First year working through this listGetting your baseline classification right now avoids years of compounding corrections.
  • Anything already missedLate FBARs or unclassified super are best addressed proactively, not after an IRS notice.
  • Life changes mid-yearA new job, property purchase, or move between states can shift several items on this list at once.
  • Unsure which items even applyA short consult can confirm your actual filing obligations before you spend hours on the wrong ones.

7. Confirm Totalization Agreement Coverage

If US-employer-sponsored, confirm your employer holds a Certificate of Coverage. If locally hired, confirm you're correctly exempt from US Social Security tax but still liable for Medicare tax if self-employed.

8. Review State Domicile Status

Confirm whether your prior US state still considers you a resident for state tax purposes, particularly if you're from California, Virginia, New Mexico, or South Carolina.

9. Check FIRB Status Before Any Property Purchase

Confirm whether you need Foreign Investment Review Board approval and budget for the foreign buyer stamp duty surcharge before signing any contract.

10. Reconcile Australian and US Tax Years

Australia's financial year runs July 1 to June 30; the US uses the calendar year. Keep a running log so you're not reconstructing figures from memory at filing time.

11. Verify Beneficiary Designations on US Accounts

Confirm 401(k), IRA, and life insurance beneficiary designations are current. Cross-border estate planning gets materially more complex the longer you're abroad, don't let this lapse.

Annual Rhythm

A Quarter-by-Quarter View

Q1 (Jan–Mar)

Gather prior-year payslips, super member statements, and passport stamps. Confirm your FEIE or FTC position for the prior US tax year.

Q2 (Apr–Jun)

File Form 1040 by the automatic June 15 expat deadline. File FBAR if the $10,000 threshold was crossed. Pay any tax owed by April 15 to stop interest accruing. Australian financial year closes June 30.

Q3 (Jul–Sep)

Lodge your Australian tax return with the ATO (October 31 deadline, later via a registered agent). If you filed a US extension, use this window to finalize figures against the closed Australian year.

Q4 (Oct–Dec)

Final extended US deadline (Oct 15). Year-end is the last window for Roth conversions and reviewing PFIC exposure inside super before the tax year closes.

FAQ: 2026 Australia Expat Checklist

Do I need to redo this checklist every year?

Yes, thresholds are indexed annually and your FEIE/FTC optimal choice can shift with income changes.

What's the single most commonly missed item on this list?

Superannuation classification (item 5). Many Americans never realize their super triggers foreign trust reporting until years have passed.
