FBAR for Americans in Australia: super counts too

An everyday transaction account, an offset account against the mortgage and a superannuation balance will clear the FBAR threshold between them without anyone mentioning it.

The FBAR is a reporting form with no tax attached, which is exactly why it gets missed. Nothing in Australia prompts it, no Australian institution mentions it, and the amounts involved are ordinary — an everyday account, an offset account sitting against a mortgage, and a super balance that has been accumulating since your first job.

The threshold is worldwide, and it is a maximum

The test is the $10,000 aggregate MAXIMUM across all your non-US financial accounts at any point during the calendar year — not the closing balance, not the average, and not only Australia. And it is a US-dollar threshold, so the arithmetic has to be done in US dollars: A$9,000 is roughly US$6,500, not US$9,000. Someone with A$14,000 in an everyday account and US$4,000 left in an account in another country is over the line, even though neither would be alone.

Australian accountReportable?Note
Everyday / transaction accountYesThe ordinary case
Offset account against a mortgageYesIt is a deposit account, whatever it offsets
Term depositYesHeld at a foreign financial institution
Superannuation (industry or retail)Generally yesReportable independently of how its income is characterised
Self-managed super fundGenerally yesThe fund's accounts, and possibly your authority over them
CommSec / Stake / SelfWealth brokerageYesReport the account, not each holding
A US-dollar account at an Australian bankYesThe currency is irrelevant; the institution's location is not
Super is the one people leave off, usually reasoning that its US tax treatment is unsettled so it cannot be reportable. The inference does not hold. The FBAR is a Bank Secrecy Act report about ACCOUNTS; it does not ask whether the income inside them is taxable, and the unsettled characterisation question has no bearing on it.

Working it out

  1. For each account, find the MAXIMUM value it reached at any point in the CALENDAR year — not the Australian financial year, and not the closing balance.
  2. Convert to US dollars at the Treasury year-end rate for that year.
  3. Add every account together, including any held outside Australia.
  4. Compare the total to $10,000. If it exceeds that figure, EVERY account is reported — not only those that individually cross it.
  5. Include accounts you have signature authority over but do not own.
  6. File FinCEN Form 114 electronically, April 15, with an automatic extension to October 15

If you have never filed

Penalties are $16,536 for non-willful violations and $165,353 where conduct is willful, but the ordinary case of someone who did not know is a compliance problem rather than an enforcement one. The IRS publishes the Delinquent FBAR Submission Procedures where returns are otherwise correct, and the Streamlined Foreign Offshore Procedures where returns are also late.

Frequently asked questions

Do I report my superannuation on the FBAR?#
Generally yes. Superannuation is a foreign financial account, and it is reportable independently of the unsettled question about how its income is characterised for US tax. The FBAR asks about accounts, not about taxability.
Is my mortgage offset account reportable?#
Yes. An offset account is a deposit account held at a foreign financial institution; what it offsets does not change its character for FBAR purposes.
Does the Australian financial year matter for the FBAR?#
No. The FBAR is measured on the calendar year, so the July-to-June Australian financial year is irrelevant to it — a common source of the wrong maximum being reported.
Does the $10,000 threshold apply only to my Australian accounts?#
No. It is the aggregate maximum across every non-US financial account you hold anywhere in the world. Australian accounts and any account left behind in another country are added together against the same $10,000 figure.
When is the FBAR due?#
It is April 15, with an automatic extension to October 15 It is filed with FinCEN rather than the IRS, and is the same $10,000 for single and joint filers
What if I have never filed one?#
The route depends on whether your tax returns are otherwise correct. Where they are, the IRS publishes Delinquent FBAR Submission Procedures; where returns are also late, the Streamlined Foreign Offshore Procedures cover the most recent 3 years and the most recent 6 years.
