U.S. citizens and residents who hold Australian superannuation may have U.S. tax and reporting obligations even in a year without contributions or withdrawals. A self-managed super fund (SMSF) raises additional questions about the trust deed, who controls the fund’s accounts, and how it was funded. Colorado Legal reviews those records alongside your U.S. returns and foreign account filings.

What determines the U.S. tax treatment of an SMSF?

An SMSF is an Australian retirement fund set up as a trust and managed by its trustees. For U.S. purposes, start with the deed and amendments, trustee appointments, each member’s rights, and the history of employer contributions, member contributions, and rollovers. These records help determine how the arrangement is classified and whether contributions, earnings, or payments have U.S. income-tax consequences. An Australian audit and annual return are useful evidence of how the fund operates. See the Australian SMSF audit rules.

For a payment from the fund, identify its source, the member’s contribution history and U.S. tax basis, and any Australian tax paid. The U.S.–Australia income tax treaty may matter, including its pension article and the saving clause that generally preserves U.S. taxing rights over U.S. citizens, subject to exceptions. The type of payment and the applicable treaty provisions matter when evaluating a distribution or rollover. See the U.S.–Australia treaty documents and the IRS foreign pension guidance.

Which U.S. reporting rules should you review?

FBAR (FinCEN Form 114)

Identify the foreign bank and brokerage accounts held by or through the fund, who owns them for FBAR purposes, and who can direct transactions. A member, individual trustee, or director of a corporate trustee may have different rights or authority. The FBAR generally applies when a U.S. person has a financial interest in or signature or other authority over reportable foreign accounts whose aggregate value exceeds $10,000 at any time during the calendar year. Review the FinCEN filing rules and our FBAR guide.

Form 8938 (FATCA)

An interest in a foreign pension or deferred compensation plan can be reportable on Form 8938 when total specified foreign financial assets exceed the applicable threshold. Filing status and whether you qualify as living abroad affect the threshold. The Form 8938 instructions also contain specific valuation rules for pension interests and coordination rules for assets reported on certain other forms. See the IRS Form 8938 instructions and our FATCA reporting guide.

Forms 3520 and 3520-A

If the arrangement is treated as a foreign trust for U.S. tax purposes, examine whether a U.S. person created or transferred property to it, is treated as an owner, or received a distribution. U.S. ownership can create annual reporting even in a year without transactions. Review the Form 3520 guide and Form 3520-A guide.

Revenue Procedure 2020-17 provides foreign trust reporting relief for eligible individuals with qualifying foreign retirement trusts. The IRS also describes when taxpayers may rely on the proposed Section 6048 regulations for eligible years ending after May 8, 2024. Reliance requires consistent application of the proposed rules in their entirety by the taxpayer and related persons. Eligibility depends on the fund, the individual, and the year under review. Any available relief under Section 6048 leaves the income-tax, FBAR, and Form 8938 questions to be evaluated under their own rules. See Revenue Procedure 2020-17 and the current IRS Form 3520 instructions.

What to gather for an Australian superannuation consultation

The trust deed and amendments, trustee or corporate trustee records, and account signing authorities.
Annual financial statements, member statements, Australian annual returns, and audit reports.
Bank and brokerage statements, investment holdings, and records of employer and member contributions, rollovers, and payments.
Prior U.S. returns, Forms 8938 and other international forms, submitted FBARs, and any written advice about the fund.

If you moved from Australia while continuing to make decisions for the fund, ask your Australian adviser to review the fund’s residency under Australian rules. The location of the fund’s central management and control is one of the statutory residency tests. See the section 295-95 of Australia’s Income Tax Assessment Act 1997.

Frequently asked questions

Do I need to report my SMSF if I took no withdrawals?

Possibly. The FBAR looks at reportable financial interests and authority over foreign accounts. Form 8938 looks at specified foreign financial assets and the applicable filing threshold. Foreign trust rules can also require annual reporting based on U.S. ownership. Each question turns on the fund and your role during the year.

Do the same rules apply to an employer super fund and an SMSF?

Start by identifying the actual arrangement and your rights in it. An SMSF member may also have trustee or director duties and authority over accounts. For an employer or retail fund, plan rules and member statements help identify the participant’s rights, contributions, and available valuation information.

What if I already filed FBARs for my Australian bank accounts?

Pull the copies you submitted and compare the listed accounts with the fund’s records. Our guide to reviewing an SMSF on prior FBARs explains what to collect and how to identify the years that need further review.
