The United States is one of only two countries in the world that taxes its citizens on worldwide income — regardless of where they live, bank, or invest. That single fact underpins a compliance framework that reaches into nearly every offshore account, foreign corporation, and international trust a U.S. person touches. Many people discover this framework only after they’ve already opened a foreign account, formed a BVI holding company, or received an inheritance through a foreign trust. At that point, the question is no longer whether to comply — it’s how to remediate without triggering penalties that can dwarf the balances involved. If you have offshore assets, or are considering them, understanding FBAR and FATCA is not optional. It is foundational.
What Is FBAR?
The Foreign Bank Account Report — formally FinCEN Form 114 — is a disclosure requirement administered by the Financial Crimes Enforcement Network (FinCEN) under the Bank Secrecy Act. It predates FATCA by decades and operates independently of the tax code.
Any U.S. person who holds a financial interest in, or signature authority over, one or more foreign financial accounts must file an FBAR if the aggregate value of those accounts exceeded $10,000 at any point during the calendar year. Note the word “aggregate”: if you have three foreign accounts worth $4,000 each, you have a filing obligation. The threshold is not per account — it is the combined high-water mark across all accounts, measured at any single moment during the year.
The FBAR is filed electronically with FinCEN (not the IRS) and is due April 15, with an automatic extension to October 15 — no action required to receive the extension.
The penalty structure is where FBAR diverges sharply from ordinary tax violations. For non-willful failures, civil penalties can reach $10,000 per violation, per year. For willful violations — where the IRS can show you knew about the obligation and disregarded it — the civil penalty is the greater of $100,000 or 50% of the account value per violation, assessed annually. Courts have allowed penalties to stack across multiple accounts and multiple years, producing assessments that exceed the total value of the accounts themselves. Beyond civil exposure, willful non-filers face potential criminal prosecution under the Bank Secrecy Act.
What Is FATCA?
The Foreign Account Tax Compliance Act, enacted in 2010 and codified primarily at IRC §6038D, operates on two parallel tracks.
The first track applies directly to U.S. persons. If you hold “specified foreign financial assets” above certain thresholds, you must attach Form 8938 to your annual federal income tax return. The thresholds depend on filing status and residency. Domestic filers (living in the United States) must file if their assets exceed $50,000 on the last day of the year or $75,000 at any point during the year (for married filing jointly, the thresholds double). U.S. persons residing abroad face higher thresholds: $200,000 on the last day of the year or $300,000 at any point during the year ($400,000/$600,000 for joint filers). The penalty for failing to file Form 8938 starts at $10,000, escalating to $50,000 for continued non-filing after IRS notice.
The second track — and the mechanism that makes FATCA genuinely global — applies to foreign financial institutions (FFIs). Under intergovernmental agreements (IGAs) negotiated between the U.S. and over 100 jurisdictions, foreign banks, brokerages, and fund administrators are required to identify U.S. account holders and report those accounts to their local tax authority, which then transmits the information to the IRS. Institutions that fail to comply face a 30% withholding tax on their U.S.-source income.
The practical consequence: foreign banks are not passive bystanders in U.S. tax enforcement. Many have concluded that U.S. person accounts create more compliance cost and regulatory risk than they are worth. Account closures and outright refusals to onboard U.S. clients are now standard practice at private banks throughout Switzerland, Singapore, the Channel Islands, and beyond. Any offshore strategy that ignores this dynamic is built on a flawed premise.
FBAR vs. Form 8938 — What’s the Difference?
A common misconception is that FBAR and Form 8938 are redundant — that filing one satisfies the other. They are not redundant. They arise from different legal authorities, are filed with different agencies, cover partially overlapping but distinct asset universes, and carry independent penalty regimes. For many offshore structures, both will be required simultaneously.
| FBAR (FinCEN 114) | Form 8938 (FATCA) | |
|---|---|---|
| Legal authority | Bank Secrecy Act | IRC §6038D |
| Filed with | FinCEN (BSA E-Filing) | IRS (attached to Form 1040) |
| Filing threshold | Aggregate > $10,000 | $50K–$300K depending on status/residency |
| What’s reported | Foreign financial accounts | Specified foreign financial assets (broader) |
| Penalties | Up to $10K non-willful; $100K+ willful | $10,000–$50,000 |
| Criminal exposure | Yes (willful violations) | No direct criminal provision |
The asset scope of Form 8938 is broader in some respects — it captures interests in foreign partnerships and foreign stock not held in a financial account, for example — while FBAR captures signature authority over accounts you don’t own. Neither form eliminates the other.
What Counts as a “Foreign Financial Account” or “Specified Foreign Financial Asset”?
The definitions are broader than most people expect. For FBAR purposes, foreign financial accounts include foreign bank accounts, foreign brokerage accounts, foreign mutual funds, and foreign-issued life insurance or annuity contracts with cash surrender value. For Form 8938 purposes, “specified foreign financial assets” extend further to include stock in foreign corporations held outside of a financial account, interests in foreign partnerships, and interests in foreign trusts and estates.
Several categories consistently catch people off guard:
Foreign pension plans. A retirement account held at a foreign institution — whether a Canadian RRSP, a UK pension, or a plan in any other jurisdiction — is generally a reportable foreign financial account for FBAR purposes and a specified foreign financial asset for Form 8938 purposes.
Foreign corporations. A U.S. person who owns shares in a foreign corporation may have FBAR and Form 8938 obligations with respect to accounts held by that corporation, depending on ownership level and control. More importantly, the corporation itself triggers separate information return obligations (discussed below).
Beneficial interests and signatory authority. The FBAR obligation extends to accounts over which a U.S. person has signature authority — even if the account is not in their name and they have no personal financial interest in it. A U.S. executive with signing rights on a foreign subsidiary’s operating account may have a personal FBAR filing obligation.
Form 5471 and Form 3520 — The Next Layer
FBAR and FATCA represent the disclosure baseline, but offshore structures involving entities trigger additional information return requirements that operate independently — and carry their own substantial penalties.
U.S. shareholders of foreign corporations — specifically those who own 10% or more of a controlled foreign corporation (CFC) — must file Form 5471, an information return that reports the corporation’s income, balance sheet, and transactions with related U.S. persons. The penalty for failure to file starts at $10,000 per year per corporation, and the IRS has authority to assess these penalties even when no additional tax is owed.
U.S. persons who create, transfer assets to, or receive distributions from foreign trusts — or who are treated as the owner of a foreign trust under grantor trust rules — must file Form 3520 (and, in many cases, Form 3520-A). Penalties for non-filing can reach 35% of the relevant transaction amount.
These obligations stack directly on top of FBAR and FATCA. In a typical offshore structuring engagement involving a foreign holding company and a discretionary trust, a U.S. person may simultaneously owe FBAR, Form 8938, Form 5471, and Form 3520 filings — each governed by separate rules, separate deadlines, and separate penalty regimes.
Common Mistakes That Create Exposure
Most FBAR and FATCA violations are not the product of intentional evasion. They result from misunderstandings that are entirely avoidable with proper guidance.
The “small account” assumption. The FBAR threshold is aggregate, not per account. A U.S. person with five foreign accounts, each worth $3,000, has a $15,000 aggregate position and a filing obligation. The fact that no single account exceeds $10,000 is irrelevant.
“I don’t owe any tax, so I don’t need to file.” FBAR is a disclosure form, not a tax form. It does not determine or affect your tax liability. The obligation to file exists regardless of whether any income was earned or any tax is owed. Many FBAR violations arise from exactly this misunderstanding.
Foreign entity accounts. A U.S. person who controls a foreign corporation or LLC cannot avoid FBAR exposure by holding the account in the entity’s name. If the U.S. person has a sufficient ownership interest in or control over the entity, the entity’s foreign accounts are attributed to them for FBAR purposes.
Overlooking non-bank assets. Foreign pension accounts, foreign brokerage accounts, and foreign insurance contracts with cash value are all reportable. The obligation is not limited to traditional bank accounts.
Voluntary Disclosure and Amnesty Options
For U.S. persons who have not been filing — whether due to ignorance of the rules or deliberate avoidance — the IRS offers structured pathways to come into compliance without facing the full penalty regime.
The IRS Streamlined Filing Compliance Procedures provide two tracks. The Streamlined Domestic Offshore Procedures apply to U.S. residents who can certify that their non-compliance was non-willful. The Streamlined Foreign Offshore Procedures apply to U.S. persons living abroad meeting a non-residency test, and for those who qualify, the penalty is zero. Both programs require filing amended returns, paying back taxes and interest, and submitting the required information returns.
The critical point: voluntary disclosure is available only to those who come forward before the IRS opens an examination or makes contact regarding the non-compliance. The window closes the moment the IRS initiates contact. Acting proactively — even if it means disclosing years of non-filing — is categorically less costly than being identified through IGA reporting or audit.
What This Means for Offshore Structuring
Any offshore structure that involves a U.S. person must treat FATCA and FBAR compliance as a first-order design constraint — not a downstream compliance task to be handled by an accountant after the structure is in place.
The architecture of a structure determines the filing obligations it generates. A U.S. person’s involvement as a grantor, shareholder, beneficiary, or signatory authority is not incidental — it drives the entire disclosure map. A structure that was tax-efficient and legally sound when established can become a significant liability if the U.S. person’s reporting obligations were never properly identified and addressed.
This is precisely the work of a Scoping Mandate engagement: before any recommendation is made regarding jurisdictions, entity types, or banking arrangements, the full disclosure landscape is mapped. What are you currently required to report? What forms are due, by which deadlines, to which agencies? Is your current structure generating obligations that are not being met? Those questions must be answered before any new structure is designed — and ideally before any offshore account is opened.
Begin with a Compliance Assessment
The first step is understanding what you’re currently required to disclose — and whether your current structure is fully compliant. For many clients, a Scoping Mandate engagement surfaces obligations that have been overlooked for years, alongside a clear remediation path that avoids the full penalty exposure of being identified through IGA reporting or audit.
If you have offshore accounts, interests in foreign entities, or are considering an international structure, begin your Scoping Mandate engagement here. The cost of getting ahead of a compliance gap is a fraction of the cost of addressing it after the fact.
