When a Foreign Pension Raises Form 3520 Questions

Some foreign pensions are arranged through trusts, insurance contracts, or pooled investments. That does not mean Form 3520 always applies, but it does mean the trust classification should be checked before the account is treated as a simple retirement account.

Collect the legal documents

Obtain the plan rules, trust deed if any, trustee details, contribution and distribution statements, beneficiary rights, employer participation, and local tax treatment. Identify who owns the assets and who controls substantial decisions.

Distinguish Forms 3520, 3520-A, and 8938

Before selecting a trust form, apply the current exceptions. Form 3520 instructions expressly exclude qualifying Canadian retirement plans under Rev. Proc. 2014-55 and provide conditional routes under Rev. Proc. 2020-17 and the May 2024 proposed-regulation reliance rule. Those exceptions do not decide income treatment or erase Form 8938, FBAR, or PFIC analysis. Map the pension before selecting a trust form.

Form 3520 can report certain foreign-trust transactions, ownership, and foreign gifts or bequests. Form 3520-A is the annual information return for a foreign trust with a U.S. owner. Form 8938 covers specified foreign financial assets under its own rules. A pension can require one, more than one, or none of these forms.

Separate the plan, the contributions, and the payment

For a foreign-pension question, collect the plan rules, administrator statement, contribution history, employer participation, investment options, vesting terms, distribution notice, and local tax treatment. Record whether the arrangement is a government benefit, employer plan, personal account, insurance contract, trust, or pooled investment. Keep treaty articles and competent-authority guidance that may affect the result, but do not assume a treaty label makes every plan tax-deferred in the United States.

Build a timeline for contributions, transfers, withdrawals, annuity payments, lump sums, and rollovers. Reconcile the local-currency amounts to U.S.-dollar workpapers and identify any information-return question separately from taxable-income treatment. A pension can be relevant to Form 8938, FBAR, Form 3520, Form 8621, or none of them depending on its structure. Flag missing plan documents and mixed insurance or investment features for professional review.

Use the foreign pensions guide for the pension overview and the expat tax filing service when classification, treaty treatment, or a lump-sum calculation cannot be supported by the plan records.

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 pensions 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.
