FBAR Versus IRS Form 8938: When Foreign Accounts Can Trigger One Filing or Both

Review the primary official source.

Two Separate Regimes, Two Different Agencies

You may need FBAR, Form 8938, or both. For FBAR, a U.S. person’s reportable foreign financial accounts generally trigger filing when their aggregate value exceeds $10,000 at any time in the calendar year. Form 8938 has separate asset definitions and higher thresholds that depend on filing status and qualifying residence abroad. Passing one test does not answer the other. These distinctions follow the IRS comparison chart and FinCEN’s FBAR guidance, checked October 20, 2026.

The FBAR is filed with the Financial Crimes Enforcement Network (FinCEN), a bureau of the U.S. Treasury, through the BSA E-Filing System. Form 8938, by contrast, is attached directly to your federal income tax return and processed by the IRS. Submitting one does not substitute for the other, and the same foreign account can appear on both forms in the same tax year.

Understanding this distinction is the first step toward knowing what records to gather and which questions to bring to a qualified tax professional. This article is general education, not legal or tax advice. Your specific situation—including your residency, filing status, account types, and ownership structure—will determine what analysis applies to you.

What Each Form Covers: Filers, Assets, and Thresholds

The two forms differ in meaningful ways across nearly every dimension. Here is a practical side-by-side overview based on official IRS and FinCEN guidance.

Who must file. The FBAR applies to U.S. persons—a category that includes citizens, residents, and certain entities—who have a financial interest in, or signature authority over, one or more foreign financial accounts. Form 8938 applies to specified individuals, including U.S. citizens, resident aliens, certain nonresident aliens who elect resident treatment, and nonresident aliens who are bona fide residents of American Samoa or Puerto Rico. Entities can also have Form 8938 obligations under certain circumstances.

U.S. possessions need separate classification. FBAR’s definition of the United States includes its territories. Form 8938 has different possession rules: The instructions exclude specified assets connected with the particular U.S. possession of which the filer is a bona fide resident. Those exclusions depend on the asset and its connection to that possession, not just a foreign-looking institution name. Identify the filer’s residence and each asset’s jurisdiction separately; see “Bona Fide Resident of a U.S. Possession” in the Form 8938 instructions.

What assets are covered. The FBAR covers foreign financial accounts, including bank accounts, brokerage accounts, mutual funds, and certain other accounts held at foreign financial institutions. Form 8938 casts a wider net: It covers specified foreign financial assets, which can include foreign financial accounts but also foreign stocks, securities, interests in foreign entities, and financial instruments or contracts with foreign counterparties—assets that may not be held in a traditional account at all.

FBAR’s aggregate threshold. The ordinary trigger is more than $10,000 across the reportable foreign financial accounts at any time during the calendar year, not $10,000 in each account. For example, two reportable accounts holding $6,000 and $5,000 at the same point in time total $11,000. Subject to the applicable filer and account rules, neither account being individually above $10,000 avoids the reporting trigger. The FBAR threshold does not increase because the filer is married or lives abroad.

Form 8938 for individuals living in the United States. An unmarried filer or married person filing separately meets the asset-value test above $50,000 on the last day of the tax year or above $75,000 at any time. For a married couple filing jointly, the corresponding amounts are above $100,000 at year-end or above $150,000 at any time. These are alternative tests: Selling an asset before December 31 does not erase a higher value earlier in the year.

Form 8938 for qualifying individuals abroad. The amounts are above $200,000 at year-end or $300,000 at any time for unmarried or separate filers, and above $400,000 or $600,000 for joint filers. The higher limits require a foreign tax home and the instructions’ presence-abroad test: A qualifying full-tax-year bona fide residence for a U.S. citizen, or at least 330 full days abroad in a qualifying twelve-month period for a citizen or resident. A foreign address alone does not establish that test. See Form 8938 instructions, “Reporting Thresholds Applying to Specified Individuals.”

Form 8938 also covers defined specified domestic entities, generally with the $50,000 year-end/$75,000 anytime thresholds; not every domestic entity falls into that category. The instructions separately say a person who is not required to file an income-tax return need not file Form 8938 solely because assets exceed its threshold. That exception does not decide FBAR. Determine the filer category and any reporting exception before applying the numbers.

Assets reported on another international form. Timely reporting on qualifying Forms 3520, 5471, 8621 or 8865 can relieve duplicate asset detail on Form 8938, but the form and number of filings must still be identified in Part IV. Foreign grantor trusts have additional Form 3520/3520-A conditions. A specified individual still counts those assets when testing the Form 8938 threshold; a specified domestic entity excludes the qualifying assets reported on another Part IV form from its threshold calculation. Do not confuse being excused from repeating asset detail with being excused from filing Form 8938. See the instructions’ “Assets Reported on Another Form,” “Duplicative Reporting” and “Foreign Grantor Trusts.”

Why one filing or both? Consider an unmarried U.S.-resident individual required to file an income-tax return, owning only a reportable foreign bank account. If it stays at $20,000 all year, it exceeds the ordinary FBAR trigger but not either individual Form 8938 threshold. If it stays at $80,000, both value tests are met, absent an applicable exception. A different asset mix changes the comparison: Directly held foreign shares outside a financial account can count for Form 8938 without being an FBAR account. These illustrations assume the stated ownership, location and filer facts; they are not a substitute for classifying every asset.

Signature authority. The ability to control the disposition of account assets by direct communication with the financial institution can trigger FBAR even without a financial interest, subject to applicable exceptions. This matters for employees, officers, and trustees managing others’ accounts. Signature authority alone generally does not make the account reportable on Form 8938. Identify the account holder and the signer’s role, then check the FBAR instructions and any role-specific relief linked by FinCEN; do not assume either that every signer is exempt or that no exception can apply.

How to Build Your Foreign-Account Inventory

Before you can determine which forms require analysis, you need a complete picture of what you hold. Use the checklist below as a starting point. This is an organizational tool, not a substitute for professional review.

• List every foreign financial institution where you have an account, including banks, brokerages, pension funds, and insurance products with cash value.
• Note your ownership type for each account: sole owner, joint owner, beneficial owner through a trust or entity, or signature-authority-only.
• Record the maximum value of each account during the calendar year, converted to U.S. dollars using the applicable Treasury or IRS exchange rate for that year.
• Identify assets held outside accounts—foreign stocks held directly, interests in foreign partnerships or corporations, and foreign-issued life insurance or annuity contracts.
• Confirm your residency and filing status for the year in question, because thresholds for Form 8938 differ for taxpayers living abroad versus those living in the United States.
• Gather prior-year filings to identify any accounts that were reported before and confirm whether they remain open or were closed during the year.
• Note any accounts over which you have signature authority but no financial interest, particularly through an employer or a fiduciary role.

Keep year-end values as well as annual highs, and retain the exchange-rate calculation. The IRS comparison chart uses a year-end exchange-rate baseline for both forms; the FBAR uses the calendar-year-end rate even though the account’s maximum value may occur earlier. Form 8938 instructions generally use the tax-year-end Treasury rate even for an asset sold earlier, with a stated account-statement exception. Joint ownership needs separate attention: The Form 8938 rules for testing a threshold can differ from the value reported once filing is required. For example, specified spouses filing separately may use half a jointly owned asset for their threshold test but each report its entire maximum value on a required Form 8938. For joint ownership with someone other than a spouse, or with a spouse who is not a specified individual, each owner uses the entire value for the Form 8938 threshold; the required reporting also uses the entire maximum value. Do not apply one convenient split to both forms or every ownership arrangement. See the instructions’ “Joint Interest Valuation” and “Reporting the Value of Jointly Owned Assets.”

The same records can support a review with a tax professional, but the account inventory should identify which form requires each item. An interest in a foreign entity is not always direct ownership of every asset it holds; entity and trust rules need their own analysis.

Assembling Records and Deciding on Next Steps

Once your inventory is complete, the next task is assembling the supporting documentation. Include the branch’s physical location, not just the bank’s national brand. The IRS chart lists a foreign branch of a U.S. institution as potentially FBAR-reportable but not Form 8938-reportable; a U.S. branch of a foreign institution appears as neither under that chart. The account location can therefore change the answer even when the institution’s name sounds foreign.

Key documents to locate and organize include annual account statements showing the highest balance during the year, correspondence from foreign financial institutions identifying account numbers and institution addresses, entity formation documents if accounts are held through a foreign company or trust, and any prior FBAR or Form 8938 filings.

A few practical points to keep in mind as you prepare:

• Use separate filing calendars. FBAR is ordinarily due April 15 following the calendar year, with an automatic extension to October 15, and is filed through FinCEN’s BSA E-Filing System rather than with the tax return. Form 8938 attaches to the annual return and follows that return’s due date, including applicable extensions. Check any applicable disaster or other special relief rather than assuming an ordinary date controls every filer.
• If you have accounts you did not previously report, do not assume a particular resolution path is available or appropriate without professional guidance. The analysis depends on facts, filing history, and current agency programs that change over time.
• An interest in a foreign pension or deferred-compensation plan can be a Form 8938 asset; that is different from the foreign-government social-security equivalent excluded by the instructions. Identify the arrangement before applying its valuation and reporting rules. Employer-sponsored accounts also require the separate FBAR interest/signature-authority analysis.

A missed form can have consequences separate from unpaid tax. The Form 8938 instructions describe a possible $10,000 failure-to-file penalty, plus continuation penalties of $10,000 per 30-day period or part after the 90-day IRS-notice period, capped at $50,000 additional. A transaction involving an undisclosed asset can also produce a 40% penalty on the resulting tax underpayment. The filing-penalty exception requires reasonable cause and no willful neglect, supported by the actual facts. FBAR has a separate civil and criminal penalty framework; willfulness, inflation-adjusted civil limits and the particular violation matter. An old dollar figure or the fact that one form was filed cannot settle the other regime’s penalty exposure. Preserve notices, submission records and the explanation for any omission for individual review.

Use the completed inventory to mark each asset as FBAR-reportable, Form 8938-reportable, both, or requiring further classification, then calculate the relevant totals and filing dates. Preserve proof of each actual submission. If the underlying money was a foreign gift or inheritance, our Form 3520 guide addresses a separate transfer-reporting question. If an FBAR penalty has already been proposed, our Bittner analysis addresses the different question of nonwillful penalty counting; it does not eliminate the filing duty.
