FATCA and Foreign Accounts: The Sequence That Protects You

Form 8938 reporting thresholds vary based on filing status and whether you live inside or outside the United States. For Americans filing as single who live abroad: you must file Form 8938 if the total value of your specified foreign financial assets exceeded $200,000 at year-end, or $300,000 at any point during the year. For married filing jointly, those thresholds double. For Americans still resident in the United States, the thresholds are lower: $50,000 at year-end or $75,000 at any point during the year for single filers.

This means Americans in the transition period — still resident in the US but building foreign accounts — face the lower domestic thresholds, not the higher abroad thresholds. An American living in Chicago who opens a foreign account and funds it with $80,000 as part of departure preparation is over the Form 8938 threshold for a US resident single filer. The account must be disclosed. This is manageable — but it is a disclosure obligation that attaches the moment the account and balance exist, regardless of the person's departure timeline.

Specified foreign financial assets for Form 8938 purposes include more than just foreign bank accounts. They include: foreign stock or securities held outside a US financial account, foreign partnership interests, foreign mutual funds, foreign-issued insurance contracts with a cash surrender value, and interests in foreign trusts and estates. Americans with any of these assets above the threshold need to file Form 8938, whether or not those assets are in a foreign bank account and regardless of whether they also trigger an FBAR obligation.

Americans frequently ask why they must report the same accounts on two different forms to two different agencies. The answer is that they are not the same thing, even when they cover the same accounts. FBAR captures all foreign financial accounts — broadly defined — above a $10,000 aggregate threshold, with no exceptions. Form 8938 captures specified foreign financial assets above a higher threshold, but with a broader asset definition that includes things that are not financial accounts.

There are foreign financial assets that must be reported on Form 8938 but not on FBAR — foreign stock held directly, interests in foreign partnerships, certain foreign insurance contracts. There are foreign accounts that must be reported on FBAR but may fall below the Form 8938 threshold. The two obligations overlap in the middle but are not coextensive at the edges. Filing one does not satisfy the other, and both carry independent penalties for non-compliance.

The sequencing question is not whether to have foreign accounts — you must — but how to structure the pre-departure account build so that you are not creating compliance exposure in the wrong order. Several specific sequences create problems that the reverse would avoid.

Opening foreign accounts before addressing prior-year compliance gaps is the most common sequencing error. If you have unfiled returns or prior FBAR failures, opening new foreign accounts that immediately create a reporting obligation draws attention to the accounts at a time when your prior-year posture is not clean. The correct sequence: address prior-year compliance using Streamlined procedures first, then build the new account infrastructure.

Transferring large assets into foreign accounts in a single year, particularly if that creates a Form 8938 threshold crossing in the year you are also preparing Form 8854 (the expatriation statement), concentrates compliance complexity into a single filing year. Distributing the account funding over two or three years, if the timeline permits, smooths the compliance load across multiple returns rather than a single departure-year return where every line is under scrutiny.

Opening accounts in jurisdictions with weak US person policies — banks that actively seek US clients in ways that may not be fully FATCA-compliant — creates a different risk: the institution may not report you to the IRS as required, which means when they eventually come into compliance (or are acquired by a compliant institution), the disclosure is unexpected from the IRS's perspective rather than orderly and anticipated from yours.

Under FATCA's intergovernmental agreement framework, foreign financial institutions in participating countries — which includes virtually every developed-country banking system — are required to identify US account holders through a combination of documentary and electronic due diligence. A US passport, a US address on file, a US phone number, a US birthplace, or instructions to transfer funds to a US account are all indicators that trigger enhanced due diligence. You cannot open a foreign bank account as an American without the bank knowing you are American.

This is not a reason to avoid foreign accounts. It is a reason to treat disclosure as the baseline assumption rather than the risk to be managed. The IRS receives reporting on US account holders from participating foreign financial institutions. That reporting exists regardless of whether you file Form 8938. Full and timely disclosure on your return matches the institutional reporting. Non-disclosure creates a discrepancy between what the IRS receives and what you report.
