Form 3520-A for a Foreign Trust: Annual U.S. Owner Reporting
Understand who is responsible for Form 3520-A, what a U.S. owner needs when the trust does not file, and how to coordinate Form 3520 and Form 8938.
Form 3520-A is the annual information return for a foreign trust with a U.S. owner. It is not a substitute for Form 3520, and it is not simply a foreign bank statement. The filing identifies the trust, its owners and beneficiaries, and the information needed to report trust activity under the U.S. rules.
Determine whether the arrangement is a foreign trust
U.S. tax classification uses a court test and a control test. A trust can be foreign for U.S. purposes even if local law calls it a pension, family settlement, savings plan, or insurance wrapper. Collect the trust deed, amendments, governing law, trustee information, beneficiary terms, and control rights.
Identify the U.S. owner
The U.S. owner is determined under the grantor-trust rules, not merely by the name on a bank statement. Contributions, transfers, retained powers, beneficiary rights, and related-party arrangements can affect the analysis. Build an ownership timeline for the full year.
When the trust does not file
The IRS instructions describe a substitute Form 3520-A process for a U.S. owner when the foreign trust fails to file. The substitute filing is attached to Form 3520 and requires the information and statements specified by the current instructions. Do not assume that a missing trustee report means no filing is required.
Coordinate the annual forms
Form 3520 can report ownership, transfers, distributions, loans, uncompensated use, and foreign gifts or bequests. Form 3520-A provides the trust’s annual information. Form 8938 may also require disclosure, and a distribution may have income consequences. Reconcile the forms to the trust’s books, bank records, and beneficiary statements.
Document checklist
- Trust instrument and amendments.
- Trustee and protector details.
- Contributions, distributions, loans, and use of trust property.
- Annual financial statements and beneficiary statements.
- U.S. owner and beneficiary information.
- U.S. agent appointment or required substitute documents.
- Related Form 3520, Form 8938, and income-reporting workpapers.
Start with the governing documents
For a foreign-trust question, obtain the trust deed, amendments, governing law, trustee and protector details, beneficiary rights, contribution history, distribution statements, loans, and year-end accounts. Identify the grantor, owner, beneficiaries, and persons with control. Record each transfer into or out of the arrangement and connect it to the bank or investment statement that proves the amount and date.
Only then map the facts to Forms 3520, 3520-A, 8938, FBAR, and the income-tax return. Separate a foreign gift or bequest from a trust transfer, and separate a distribution from a loan or reimbursement. Check whether the arrangement is treated as a grantor or non-grantor trust for the relevant U.S. purpose and whether a U.S. owner creates an annual foreign-trust filing. The local name of a foundation, pension, savings plan, or family arrangement does not answer those questions.
Use the foreign trusts guide as the companion framework and the expat tax filing service when the documents do not clearly establish ownership, classification, or the reportable event.
A practical evidence packet
The strongest way to use this page is to turn the question into a dated evidence packet rather than relying on a product label, a remembered balance, or a single tax-software screen. Start with the document that proves the legal relationship, then preserve the records that show what happened during the year. Keep the original file, the translated or summarized version if needed, and a short note explaining why the document belongs in the analysis.
Before deciding that a rule applies, record the filing year, your U.S. status, where you lived and worked, the legal owner of the asset or income, and any country-specific tax already paid. Those facts often change the result more than the name of the account or visa. Compare the result against the foreign trusts guide, then use the expat tax filing service when the inventory needs a documented review.
Use a simple decision log with four columns: fact, source document, rule or form affected, and unresolved question. Mark assumptions separately from verified facts. This makes it easier to update the work when an institution corrects a statement, a treaty protocol changes, or the IRS and FinCEN publish new instructions. It also prevents the same account or income item from being counted twice or omitted from a related form.
Common failure modes
The most common failure is treating a general answer as a conclusion for a specific structure. A foreign label, a tax-free local result, a treaty headline, or an old filing can be a useful lead, but none is a substitute for the current form instructions and the governing documents. Another failure is collecting only year-end numbers. Many cross-border tests depend on a maximum value, a transaction during the year, a residence date, or an election that must be preserved in the return workpapers.
Do not delete ambiguous records. Keep them in a review queue with the question they create. A good queue distinguishes “document missing,” “classification uncertain,” “value needs reconstruction,” and “professional interpretation required.” That separation lets straightforward work continue while protecting the issues that should not be guessed.
Before submitting anything
Reconcile the draft against the source documents, prior-year filings, related information returns, and the final conversion or calculation worksheet. Confirm that names, identification numbers, dates, ownership percentages, currencies, and addresses are consistent. Save the filed copy, acceptance or confirmation record, and the working papers together. If the result depends on a legal opinion, treaty position, willfulness determination, immigration status, or a specialist classification, stop at the boundary described above and escalate that question rather than presenting an educational checklist as advice.
Scope boundary
This article is educational and does not classify a trust or determine the filing obligation for a pension, insurance policy, or family arrangement. Foreign-trust penalties and ownership rules are high stakes. FileAbroad can organize Form 3520/3520-A preparation within a written scope through the expat tax intake.

Frequently Asked Questions
Who files Form 3520-A?
Form 3520-A is the annual information return of a foreign trust with a U.S. owner. The foreign trust is generally responsible, but the U.S. owner may need to file a substitute Form 3520-A with Form 3520 when the trust does not file.
Is Form 3520-A the same as Form 3520?
No. Form 3520 reports certain transactions with foreign trusts, ownership, and foreign gifts or bequests. Form 3520-A reports the foreign trust’s annual information and U.S. owners and beneficiaries.
Do I need a U.S. agent?
A U.S. agent can affect the information and document requirements, but the trust terms and current Form 3520-A instructions control.
