Important: Two Separate and Cumulative Obligations
FBAR (FinCEN Form 114) and Form 8938 are two separate and cumulative reporting obligations for U.S. persons with foreign financial accounts or assets. Both must be filed when applicable. The IRS receives data from thousands of foreign financial institutions under FATCA. Unreported foreign accounts are increasingly likely to be identified. Clients with foreign account issues should seek qualified tax counsel immediately.
Key Points: Practitioner Reference Before You Advise
- FBAR (FinCEN Form 114): Required under 31 U.S.C. 5314 when a U.S. person has a financial interest in, or signature authority over, foreign financial accounts with an aggregate maximum value exceeding $10,000 at ANY point during the calendar year. Filed with FinCEN (not the IRS). Due April 15; automatic extension to October 15 (no request required). Confirm current requirements under 31 C.F.R. 1010.350 and at FinCEN.gov.
- Form 8938 (FATCA): Required under IRC 6038D and Treas. Reg. 1.6038D-1 when a U.S. taxpayer holds specified foreign financial assets (SFFAs) above applicable thresholds. Filed WITH the federal income tax return (IRS), not with FinCEN. Thresholds vary by filing status and residency; confirm all current threshold amounts at IRS.gov before advising any client.
- FBAR non-willful penalty after Bittner v. United States (2023): The Supreme Court held in Bittner v. United States (2023) that the non-willful FBAR penalty applies per REPORT (one FBAR per year), not per account. Hedge the exact penalty amount to 31 U.S.C. 5321(a)(5)(B) and current IRS.gov figures (subject to inflation adjustment). Bittner applies to non-willful violations only.
- FBAR willful penalty: The greater of a statutory maximum amount OR 50% of the balance in the account at the time of the violation (31 U.S.C. 5321(a)(5)(C)). Hedge exact statutory amounts to IRS.gov (subject to inflation adjustment). The willful penalty can compound across multiple years and multiple accounts. Criminal penalties under 31 U.S.C. 5322 may also apply.
- Streamlined Procedures: SDOP (Streamlined Domestic Offshore Procedures) for U.S. residents: 5% miscellaneous offshore penalty on the highest aggregate balance. SFOP (Streamlined Foreign Offshore Procedures) for qualifying non-U.S. residents: zero penalty. Both require a non-willfulness certification under penalties of perjury and the same 3-year amended return / 6-year FBAR filing requirement. Hedge all program specifics to current IRS.gov guidance.
- Current voluntary disclosure for willful cases: The formal Offshore Voluntary Disclosure Program (OVDP) ended September 2018. Current voluntary disclosure for willful violations is through the IRS Criminal Investigation (CI) Voluntary Disclosure Practice (VDP), per the August 2018 CI Memorandum. The CI VDP does not guarantee immunity from prosecution. Hedge all VDP mechanics to current IRS.gov CI VDP guidance.
- FATCA and offshore detection risk: FATCA (IRC 1471-1474) requires foreign financial institutions (FFIs) to report U.S. account holders to the IRS or face 30% withholding on U.S.-source payments. The IRS now receives data from thousands of FFIs under intergovernmental agreements (IGAs). Unreported foreign accounts in IGA-partner jurisdictions carry a materially elevated detection risk. Practitioners should treat any unreported offshore account as an urgent compliance matter.
FBAR and Form 8938 FATCA compliance is one of the highest-stakes areas of U.S. international tax practice. The penalty exposure is severe, the definitions of who must file are broader than most clients expect, and the IRS now receives offshore account data from thousands of foreign financial institutions that reduces the practical chance of non-detection. This guide is written for enrolled agents, CPAs, and tax attorneys who need a working command of both regimes: who must file, what accounts and assets are covered, how willful and non-willful penalties are calculated and contested, what Bittner v. United States (2023) changed, how to select the correct voluntary compliance path, and how FATCA's foreign financial institution reporting network has transformed the enforcement environment.
All statutory citations, regulatory thresholds, penalty amounts, and IRS procedures referenced in this guide must be verified against current law, current IRS and FinCEN guidance, and applicable court decisions before being relied on in any specific client matter. This guide is for informational purposes only and does not constitute legal or tax advice.
Section 1: Who Must File an FBAR and When
The Basic FBAR Obligation
Under 31 U.S.C. 5314 and 31 C.F.R. 1010.350, any U.S. person who has a financial interest in, or signature authority over, one or more foreign financial accounts with an aggregate maximum value exceeding $10,000 at any time during the calendar year must file FinCEN Form 114 (FBAR) with the Financial Crimes Enforcement Network (FinCEN). The FBAR is filed with FinCEN through the BSA E-Filing System, NOT with the IRS. It is not attached to the income tax return, and it is not transmitted through the tax return e-file channel.
The FBAR due date is April 15 of the year following the calendar year reported. An automatic extension to October 15 applies; no extension request is needed. Confirm the current due date and any procedure changes at FinCEN.gov and IRS.gov before advising clients.
The definitions of "U.S. person," "financial interest," "signature authority," and "foreign financial account" under 31 C.F.R. 1010.350 are each specific and often broader than clients anticipate. Practitioners must apply the regulatory definitions, not a common-sense reading, before concluding a client has no FBAR obligation.
What Is a "Foreign Financial Account"
A foreign financial account for FBAR purposes broadly includes bank accounts (checking and savings), brokerage accounts, mutual fund accounts, and certain foreign insurance policies and annuity contracts with a cash value, held at a foreign financial institution. The FBAR coverage is not limited to "checking" and "savings" accounts; the scope is determined by 31 C.F.R. 1010.350 and applicable FinCEN guidance. Certain asset types (direct ownership of foreign real estate, foreign securities held directly with the issuer rather than through a custodial account) are generally not covered, but practitioners should hedge each specific asset type to the applicable regulatory definition before concluding it is outside the FBAR scope.
What Is a "Financial Interest"
Under 31 C.F.R. 1010.350(e), a U.S. person has a financial interest in a foreign financial account if the person is the owner of record or holder of legal title. Financial interest also extends to ownership through a foreign entity where the U.S. person owns more than 50% of the entity's stock, profit interest, or capital interest; to a U.S. person who is the grantor of a foreign trust that holds the account; and to certain nominee arrangements where the record owner holds the account on behalf of the U.S. person. These extended definitions frequently surprise clients who believe a corporate layer or a trustee structure eliminates the FBAR obligation.
Signature Authority Without Financial Interest
Under 31 C.F.R. 1010.350(f), a U.S. person with signature authority over a foreign financial account must file an FBAR for that account even if the person has no financial interest in it. This obligation commonly arises for U.S. employees of multinational corporations who have check-signing authority over foreign subsidiary operating accounts. A U.S. CFO or treasurer with authority to control disbursements from a foreign corporate account has a personal FBAR obligation for that account, separate from any corporate FBAR obligation. This is frequently overlooked at intake.
Notably, a person with signature authority but no financial interest must file an FBAR for the foreign account but does NOT need to report that account on Form 8938. This is one of the cleaner distinctions between the two regimes. Hedge to 31 C.F.R. 1010.350 and Treas. Reg. 1.6038D-2 for the specific boundaries of this distinction.
For clients who are determining whether they qualify as U.S. residents, and therefore whether the FBAR obligation applies to them at all, the residency analysis under federal tax law is a companion question. The state residency analysis for high-net-worth individuals who claim non-U.S. residency is a related but distinct inquiry; see our state income tax residency and domicile practitioner guide for the 183-day rule and statutory residency issues that arise when a client asserts foreign residency.
Special Situations: Joint Accounts, Inherited Accounts, and Foreign Retirement Plans
Joint accounts: If a U.S. person holds a joint account with a non-U.S. spouse or family member, the full account value (not just the U.S. person's pro-rata share) counts toward the FBAR aggregate threshold. The U.S. person's 50% share does not reduce the FBAR reporting obligation. Hedge the specific aggregation rule to 31 C.F.R. 1010.350(e) and current FinCEN guidance.
Inherited foreign accounts: Inheriting a foreign account can create an immediate FBAR obligation in the year of inheritance if the aggregate threshold is met. The inherited account may also generate U.S. income tax obligations depending on the account type and the applicable treaty provisions. Hedge the specific treatment of inherited foreign accounts to applicable provisions and IRS.gov before advising.
Foreign retirement accounts: Government-mandated foreign retirement savings accounts (such as the Canadian RRSP/RRIF, the UK ISA, or the Australian Superannuation fund) may or may not constitute "foreign financial accounts" subject to FBAR, and may or may not be "specified foreign financial assets" subject to Form 8938, depending on applicable treaty provisions and IRS guidance. These are high-variation situations; hedge the treatment of each specific foreign retirement account type to the applicable treaty provision, IRS.gov, and FinCEN guidance before concluding a particular account is inside or outside the reporting obligation.
PRACTITIONER PROTOCOL: FBAR FILING MECHANICS
The FBAR is filed through FinCEN's BSA E-Filing System, completely separate from the IRS e-file system. It is not transmitted with the tax return. Practitioners who prepare FBARs must register separately with the BSA E-Filing System. The April 15 due date and automatic October 15 extension apply; no extension request is filed. Confirm all current filing procedures and system requirements at FinCEN.gov before preparing or submitting any FBAR on a client's behalf.
Section 2: Form 8938 -- The FATCA Overlay
The IRC 6038D Obligation
Form 8938 (Statement of Specified Foreign Financial Assets) is required under IRC 6038D and Treas. Reg. 1.6038D-1. It is filed as an attachment to the federal income tax return. For individuals, it attaches to Form 1040. If a taxpayer had a Form 8938 obligation but did not file it with the original return, the form must be filed through an amended return (Form 1040-X) for that year.
The Form 8938 threshold is not a single figure. It varies by filing status (unmarried vs. married filing jointly) and by whether the taxpayer resides in the United States or abroad. The thresholds for foreign-based filers are higher than the thresholds for U.S.-based filers. The Form 8938 threshold test applies both at year-end AND at any point during the year. Do NOT state specific Form 8938 threshold dollar amounts in advice to clients without confirming the current figures at IRS.gov; the thresholds may be subject to change. A U.S.-based single filer who does not meet the year-end threshold should still check whether the threshold was exceeded at any point during the year.
Specified Foreign Financial Assets: Broader Than FBAR Coverage
"Specified foreign financial assets" (SFFAs) under IRC 6038D include:
- Foreign financial accounts held at foreign financial institutions (the same basic category covered by the FBAR)
- Stock in a foreign corporation not held through an account at a financial institution
- Interests in a foreign partnership not held through a financial account
- Notes, bonds, or other debt instruments issued by a foreign person and not held in a financial account
- Interests in foreign pension plans and foreign deferred compensation plans
- Interests in foreign trusts and foreign estates
- Foreign financial instruments and contracts with a foreign counterparty
The result is that Form 8938 covers MORE types of assets than the FBAR (foreign entity interests, directly held instruments), but at HIGHER thresholds (hedge to IRS.gov for the current amounts). A client below the Form 8938 threshold can still owe an FBAR. A client with a large interest in a foreign partnership but only modest foreign bank accounts may trigger Form 8938 through the partnership interest alone while being close to or below the FBAR threshold on the bank accounts. Practitioners must evaluate each regime's threshold independently. For companion reporting obligations on foreign corporate and partnership interests, see the Form 5471 and Form 5472 foreign corporation and partnership reporting practitioner guide, which covers the information return obligations that commonly arise alongside FBAR and Form 8938 in the same multinational client engagement.
The Dual-Filing Trap: Both Must Be Filed
When both FBAR and Form 8938 are triggered by the same facts, both must be filed. There is no "FBAR is enough" exemption from Form 8938, and no "Form 8938 is enough" exemption from the FBAR. The Form 8938 instructions address the coordination rules between the two obligations; practitioners should review those instructions directly for the current coordination guidance rather than relying on a general summary.
A person who files Form 8938 will generally also need to file an FBAR (because the Form 8938 thresholds are higher than the FBAR's $10,000 aggregate threshold, so meeting the Form 8938 threshold implies meeting the FBAR threshold on the underlying foreign financial accounts). But an FBAR filer does not necessarily also owe Form 8938: if the foreign financial accounts that trigger the FBAR do not push total SFFAs above the Form 8938 threshold, Form 8938 is not required for that year. And a person with signature authority but no financial interest must file an FBAR for the relevant account but does not need to report that account on Form 8938.
The penalties for failing to file each form are separate and cumulative. A single failure to disclose a foreign bank account above both thresholds can generate both FBAR penalty exposure and Form 8938 penalty exposure simultaneously.
PRACTITIONER PROTOCOL: ANALYZE EACH REGIME INDEPENDENTLY
Do not assume that the client who meets one threshold meets the other, or that the client below one threshold is below both. Pull the facts on each account and asset category. Apply the FBAR aggregate threshold test (31 C.F.R. 1010.350) independently. Apply the Form 8938 threshold test (IRC 6038D; confirm current amounts at IRS.gov) independently. If both are triggered, both must be filed -- with separate filing systems, separate deadlines (the FBAR is not attached to the return), and separate penalty exposure for any failure.
Section 3: Penalties -- Willful vs. Non-Willful FBAR Violations
The Willfulness Standard
The single most consequential factual determination in FBAR enforcement is whether the taxpayer's non-compliance was willful or non-willful. The penalty exposure differs dramatically between the two categories, and the remediation path (discussed in Sections 4 and 5) is governed almost entirely by which category applies.
Willfulness in the FBAR context means intentional or reckless disregard of a known legal duty. Courts have also applied the "willful blindness" doctrine: a taxpayer who deliberately avoided knowing about a legal duty they suspected existed can be treated as willful even if they did not have actual, affirmative knowledge. The IRS has taken the position that reckless disregard of a known legal duty satisfies the civil willfulness standard, and a number of courts have agreed.
In practice, the following facts tend to elevate willfulness risk in an examination: checking "No" on Schedule B's foreign account question while holding a foreign account; receiving foreign-source interest or dividend income reported on a Form 1099 or Form 1042-S while not disclosing the underlying account; having signed a tax return prepared by a professional who asked about foreign accounts; and having received statements or correspondence from a foreign financial institution indicating a U.S. tax reporting obligation.
Hedge the current state of the willfulness standard to applicable case law in the relevant circuit and current IRS enforcement guidance before characterizing any client's conduct as non-willful. The distinction is a legal and factual determination, not a simple self-assessment by the client.
Non-Willful Penalty After Bittner v. United States (2023)
The non-willful FBAR civil penalty under 31 U.S.C. 5321(a)(5)(B) is subject to a statutory maximum per violation, which is subject to inflation adjustment. Do not state a specific dollar amount without confirming the current figure at IRS.gov; the amounts change and citing a superseded figure creates a compliance risk.
In Bittner v. United States (2023), the Supreme Court held that the Bank Secrecy Act's non-willful FBAR penalty applies per REPORT (one FBAR per year), not per account. A taxpayer who had 15 foreign accounts in Year 1 and failed to file the FBAR for that year faces one non-willful violation for Year 1, not 15. This was a significant taxpayer-favorable ruling that resolved a circuit split: prior to Bittner, the Fifth Circuit had applied the penalty per account (one penalty per unreported account) while another approach applied it per form. The Supreme Court's per-report standard is the most favorable reading for non-willful filers with large numbers of accounts.
Practitioners advising clients with multi-year FBAR non-compliance should recalculate the non-willful penalty exposure under the Bittner per-report framework and compare it to any prior IRS penalty calculations that were made under a different interpretation. Important limitations: (a) Bittner applies only to non-willful violations; willful penalties are still assessed per account per year; (b) confirm the current IRS enforcement posture on Bittner at IRS.gov, as the IRS has taken positions in some cases that attempt to narrow the holding; and (c) the willful/non-willful distinction is the threshold question that determines whether Bittner is even relevant.
Willful Penalty
For willful FBAR violations, 31 U.S.C. 5321(a)(5)(C) authorizes a civil penalty of the GREATER OF a statutory maximum amount OR 50% of the balance in the account at the time of the violation. The 50% figure is expressly stated in the statute. The statutory maximum floor is subject to inflation adjustment; confirm the current floor amount at IRS.gov before advising any client on willful penalty exposure.
The willful penalty is assessed per account per year. A taxpayer with three foreign accounts in each of five years of willful non-compliance faces potential willful penalty exposure calculated on each of those 15 account-years. Where the 50% alternative applies and the account balances are large, the aggregate willful penalty can far exceed the actual account balance. Practitioners must map the willful penalty exposure carefully before advising on remediation options.
Criminal Exposure
A willful FBAR violation can also constitute a criminal offense under 31 U.S.C. 5322. Criminal penalties for willful FBAR violations may include fines and/or imprisonment; hedge all criminal penalty specifics to 31 U.S.C. 5322 and IRS.gov. Criminal enforcement of FBAR violations requires referral to the Department of Justice. Where willfulness is present or suspected, the practitioner must assess criminal exposure in coordination with criminal defense counsel, not merely compare civil penalty tracks.
Form 8938 Penalties
Under IRC 6038D(d), the initial penalty for failure to file Form 8938 is $10,000 per failure. If the failure continues after the IRS provides the taxpayer with notice, an additional $10,000 per 30-day period applies (up to a statutory maximum; hedge the current maximum to IRC 6038D(d)(2) and IRS.gov). These penalties are separate from the FBAR civil penalty and can apply simultaneously.
In addition to the failure-to-file penalty, IRC 6662(j) imposes a 40% accuracy-related penalty (double the standard 20% rate) on any underpayment of tax attributable to an undisclosed specified foreign financial asset. If a taxpayer failed to file Form 8938 AND had unreported income from the same foreign assets, both the IRC 6038D(d) failure-to-file penalty and the IRC 6662(j) accuracy-related penalty can apply.
Failure to file Form 8938 also triggers a significant statute of limitations extension. Under IRC 6501(c)(8), if Form 8938 was not filed, the statute of limitations on the entire income tax return for that year is extended to 3 years after the date Form 8938 is eventually filed. If the form is never filed, the return may remain open indefinitely. Additionally, IRC 6501(e)(1)(A)(ii) provides a 6-year statute of limitations when the taxpayer omits more than the applicable statutory threshold in gross income attributable to a specified foreign financial asset. For a full treatment of these SOL extensions in the context of the overall assessment statute framework, see our IRC 6501 audit statute of limitations practitioner guide.
PRACTITIONER PROTOCOL: WILLFULNESS IS THE THRESHOLD DETERMINATION
Do not characterize a client's FBAR non-compliance as non-willful without a careful review of all facts: what the client knew about the foreign accounts, whether the accounts were disclosed to prior preparers, what the client answered on Schedule B in prior years, whether the client received statements or notices from the foreign financial institution indicating a U.S. reporting obligation, and whether the client engaged in any active steps to conceal the accounts. A conclusion that the conduct was non-willful determines the Streamlined Procedures path; a wrong conclusion exposes the client to full willful penalties plus potential false statement liability for the non-willfulness certification.
Section 4: Streamlined Filing Compliance Procedures
The IRS Streamlined Filing Compliance Procedures provide a reduced-penalty path for U.S. taxpayers who non-willfully failed to file FBARs or report foreign income. The program has two tracks based on residency. Confirm all current program terms, penalty calculations, and eligibility criteria at IRS.gov before advising any client; the program terms may be updated and this guide does not substitute for current IRS.gov guidance.
Streamlined Domestic Offshore Procedures (SDOP)
The SDOP is available to U.S. residents who non-willfully failed to file FBARs or report foreign income. Requirements include:
- File amended income tax returns for the most recent 3 years for which the U.S. tax return due date has passed
- File amended FBARs for the most recent 6 years for which the FBAR due date has passed
- Pay all tax, interest, and accuracy-related penalties due on the amended returns
- Pay a 5% miscellaneous offshore penalty, calculated on the highest aggregate balance or value of the taxpayer's unreported foreign financial accounts and specified foreign financial assets during the 6-year FBAR period covered by the submission
- Sign and submit a non-willfulness certification under penalties of perjury
Hedge the SDOP 5% penalty calculation method to the current IRS.gov Streamlined Filing Compliance Procedures guidance. The calculation rules for the highest aggregate balance, the assets included in the base, and the specific submission procedures are detailed and must be followed precisely. An SDOP submission that does not comply with the calculation methodology can be rejected or treated as a non-streamlined submission.
Streamlined Foreign Offshore Procedures (SFOP)
The SFOP is available to U.S. taxpayers who qualify as non-U.S. residents. The residency requirement is specific: the taxpayer must have been residing outside the United States during at least one of the 3 prior calendar years for which a U.S. tax return was due. This is a tax residency test, not a simple "I was abroad" test; hedge the specific residency qualification to the current IRS.gov SFOP guidance before advising any client on SFOP eligibility.
For qualifying taxpayers, the SFOP imposes zero offshore penalty. The filing requirements are the same as the SDOP: 3 years of amended returns, 6 years of FBARs, payment of all tax and interest due, and a non-willfulness certification signed under penalties of perjury. The zero-penalty feature makes the SFOP highly favorable for qualifying non-willful filers, which is why the residency eligibility test must be applied carefully and not assumed.
The Non-Willfulness Certification and Its Risks
Both SDOP and SFOP require the taxpayer to certify, under penalties of perjury, that the failure to comply was non-willful. This is the most consequential representation in the submission. The IRS can challenge the non-willfulness certification during or after the streamlined process, and if the IRS determines that the conduct was actually willful, the Streamlined Procedures do not apply. In that case, the taxpayer faces full willful FBAR penalties under 31 U.S.C. 5321(a)(5)(C) as if the streamlined submission had never been made, and also faces potential criminal exposure for the false statement in the certification.
Practitioners must conduct a thorough factual investigation before recommending the Streamlined Procedures. The non-willfulness certification is not a safe harbor and it is not a formality. Where the facts on willfulness are ambiguous, the practitioner should obtain a careful legal analysis before recommending the streamlined path.
Who Should NOT Use the Streamlined Procedures
- Taxpayers who may be willful or where the willfulness determination is unclear after a thorough factual review
- Taxpayers who are already under IRS audit or examination, or who have already been contacted by the IRS about the foreign accounts
- Taxpayers who have received a criminal referral or who know they are the subject of a DOJ or IRS Criminal Investigation inquiry
- Taxpayers for whom the non-willfulness certification would be false or whose facts cannot credibly support the certification
PRACTITIONER PROTOCOL: HEDGE ALL STREAMLINED SPECIFICS TO IRS.GOV
The Streamlined Filing Compliance Procedures are described at IRS.gov and the program terms, penalty calculation rules, and submission procedures are subject to change. Before advising any client to use the SDOP or SFOP, confirm all current program requirements directly at IRS.gov. Do not rely on summaries, prior submissions, or guidance from a different tax year without verifying the current rules. A submission that does not comply with current IRS.gov requirements can be rejected or treated as a non-qualifying submission, exposing the client to full penalty exposure.
Section 5: Voluntary Disclosure for Willful Cases
After OVDP: The IRS CI Voluntary Disclosure Practice
The IRS formally ended the Offshore Voluntary Disclosure Program (OVDP) in September 2018. For taxpayers whose FBAR non-compliance may be willful, or where the facts are too ambiguous to support a non-willfulness certification, the current path is the IRS Criminal Investigation (CI) Voluntary Disclosure Practice (VDP), established under the August 2018 CI Memorandum.
The CI VDP is a separate and more comprehensive process than the Streamlined Procedures. It is not limited to offshore issues: the CI VDP applies to any taxpayer who is making a voluntary disclosure of potential criminal tax liability, including willful FBAR violations. Hedge all CI VDP mechanics, requirements, and current procedures to IRS.gov and the current CI VDP guidance, as the VDP terms and procedures may have been updated since the August 2018 CI Memorandum.
What the CI VDP Offers and What It Does Not Guarantee
The CI VDP provides an opportunity for a taxpayer to come forward and disclose potential criminal liability before the IRS identifies the taxpayer through its own investigation or through third-party information. A timely, complete, and cooperative CI VDP submission substantially reduces (but does not eliminate) the risk of criminal prosecution. The CI VDP does NOT guarantee immunity from prosecution.
The CI VDP process involves a preliminary disclosure followed by a full accounting of the unreported income and accounts, cooperation with the IRS examination team, and payment of tax, interest, and civil penalties negotiated as part of the disclosure. The penalty terms under the CI VDP are generally more punitive than the Streamlined Procedures but substantially less severe than a criminal prosecution or a contested civil examination where the IRS asserts full willful penalties.
The "Race to the IRS": Timing Is Critical
Voluntary disclosure protection under the CI VDP ends once the taxpayer is "under examination" or once the IRS has received information from a third party specifically about the taxpayer's unreported accounts. FATCA's foreign financial institution reporting network creates urgency for potential willful violators: if the taxpayer's foreign bank has reported the account to the IRS under FATCA or an IGA, the IRS may already have the relevant data, and the window for protective voluntary disclosure may be closing or closed.
Practitioners who receive a new client with potential willful FBAR exposure should immediately assess whether the relevant foreign accounts are held at institutions that participate in FATCA reporting or that are covered by an IGA with the U.S. If the accounts are at institutions in major IGA-partner jurisdictions (the UK, Germany, Switzerland, Canada, Singapore, Hong Kong, and others), the risk that the IRS already has the account data is substantial.
PRACTITIONER PROTOCOL: CRIMINAL DEFENSE COUNSEL COORDINATION FOR WILLFUL CASES
Where a potential willful FBAR violation is identified, the practitioner should coordinate with criminal defense tax counsel before making any submission or communication to the IRS. The CI VDP submission and the related civil examination are conducted under conditions that have direct criminal law implications. Decisions about what to disclose, when to disclose, and how to characterize the facts have consequences that go beyond the civil penalty outcome. Do not recommend the CI VDP or advise a potentially willful client to contact the IRS without first consulting criminal defense counsel experienced in tax matters.
Section 6: FATCA and the Shrinking Offshore World
How FATCA FFI Reporting Works
The Foreign Account Tax Compliance Act (FATCA), enacted in IRC 1471-1474, created a parallel information reporting network that feeds the IRS with data about U.S. persons' foreign accounts from foreign financial institutions (FFIs) themselves. Under FATCA, FFIs must identify their U.S. account holders and report those accounts to the IRS (or to their local tax authority under an intergovernmental agreement), or face a 30% withholding tax on certain U.S.-source payments made to them.
The practical effect for practitioners: the IRS now receives account data from thousands of FFIs worldwide, covering account holder names, taxpayer identification numbers, account numbers, account balances, and income paid. This means the IRS has an independent source of information about unreported foreign accounts that does not depend on the taxpayer's voluntary disclosure. A client who has not filed an FBAR and has not reported a foreign account on Form 8938 may already be in the IRS's systems as a result of FATCA FFI reporting.
Intergovernmental Agreements (IGAs)
The U.S. has entered into intergovernmental agreements (IGAs) with most major financial centers, including (but not limited to) Switzerland, the United Kingdom, Germany, France, Canada, Australia, Singapore, Hong Kong, Japan, and many others. Under IGAs, the foreign country's domestic financial institutions report U.S. account data to their local tax authority, which then automatically exchanges that data with the IRS. This Model 1 IGA structure means the IRS receives data from essentially every major banking jurisdiction without needing to conduct individual treaty requests.
Practitioners should treat any unreported foreign account held at a financial institution in an IGA-partner jurisdiction as a high-detection-risk situation. The IGA exchange is automatic and systematic; it does not require a specific IRS inquiry to trigger. Confirm the current list of U.S. IGA partner jurisdictions at the U.S. Treasury's IGA list and IRS.gov; the list changes as new IGAs are finalized.
Common Reporting Standard (CRS)
The OECD's Common Reporting Standard (CRS) is a multilateral equivalent of FATCA adopted by most major economies other than the United States. While the U.S. has not adopted CRS as a recipient country, U.S. taxpayers with accounts in CRS-participating countries may have their account data exchanged among CRS-participating jurisdictions. In some cases, data from a CRS exchange may ultimately reach the IRS through treaty mechanisms or other channels. Hedge CRS specifics to the OECD's CRS guidelines and the applicable tax treaty before advising any client whose foreign accounts are held in CRS-participating jurisdictions.
The Practical Takeaway for Practitioners
The era of maintaining undisclosed offshore accounts at foreign banks in traditional financial privacy jurisdictions is effectively over for most U.S. taxpayers. FATCA's FFI reporting network, supplemented by OECD CRS exchanges and bilateral tax treaty information sharing, has created a comprehensive data infrastructure that the IRS can and does use to identify U.S. persons with unreported foreign accounts. Practitioners should advise clients with any offshore account that the assumption of non-detection is no longer supportable for accounts at major financial institutions, and that the urgency of voluntary compliance is substantially higher than it was before FATCA's implementation.
PRACTITIONER PROTOCOL: ASSUME THE IRS HAS THE DATA
For any client with an unreported foreign account held at a financial institution in a FATCA-partner or IGA-partner jurisdiction, the practitioner should operate from the assumption that the IRS may already have received account data from that institution under FATCA reporting. This changes the timing analysis for voluntary disclosure substantially: the question is not "will the IRS find out" but "has the IRS already received the data." If there is any doubt, the most conservative approach is to move toward a voluntary disclosure promptly, before the IRS opens a formal examination or sends an inquiry letter that eliminates the streamlined and VDP options.
Frequently Asked Questions
Common questions from enrolled agents, CPAs, and tax attorneys on FBAR FinCEN 114, Form 8938 FATCA, offshore penalties, and voluntary compliance.
What is the FBAR and who must file it?
The FBAR (FinCEN Form 114) is required under the Bank Secrecy Act (31 U.S.C. 5314) for any U.S. person who has a financial interest in, or signature authority over, one or more foreign financial accounts with an aggregate value exceeding $10,000 at any point during the calendar year. The FBAR is filed with the Financial Crimes Enforcement Network (FinCEN), NOT with the IRS, and is due April 15, with an automatic extension to October 15 (no extension request is required). "U.S. person" includes U.S. citizens, residents, and certain domestic entities. The definitions of "financial interest," "signature authority," and "foreign financial account" under 31 C.F.R. 1010.350 are broader than most clients expect; confirm current requirements at FinCEN.gov.
How is Form 8938 different from the FBAR?
Form 8938 (required under IRC 6038D and FATCA) is filed with the federal income tax return and covers "specified foreign financial assets" (SFFAs), which are broader than just foreign financial accounts: they include foreign stocks, partnership interests, foreign pension plans, and certain financial contracts. The Form 8938 thresholds are higher than the FBAR's $10,000 threshold and vary by filing status and residency; confirm the current amounts at IRS.gov. Both forms are required when applicable; there is no exemption from one because of filing the other. Generally, a Form 8938 filer will also need to file an FBAR, but an FBAR filer does not always also need to file Form 8938 (for example, if the SFFA threshold is not met or if the FBAR obligation arises from signature authority without a financial interest).
What is the difference between willful and non-willful FBAR violations?
A non-willful violation is an unintentional failure to file or report resulting from negligence, mistake, or inadvertence. A willful violation involves intentional or reckless disregard of a known legal duty; courts have also found willfulness based on "willful blindness" (deliberately ignoring a known risk). The distinction is critical: willful penalties under 31 U.S.C. 5321(a)(5)(C) are the greater of a statutory maximum (subject to inflation adjustment; confirm at IRS.gov) or 50% of the account balance at the time of the violation, and can be assessed per account per year. Non-willful penalties after Bittner v. United States (2023) are assessed per report (one per year). Criminal penalties under 31 U.S.C. 5322 are only available for willful violations.
What did the Supreme Court decide in Bittner v. United States?
In Bittner v. United States (2023), the Supreme Court held that the Bank Secrecy Act's non-willful FBAR penalty applies per REPORT (one FBAR filing per year), not per account. This was a taxpayer-favorable decision that significantly limited the IRS's ability to impose multiple non-willful penalties on taxpayers with many foreign accounts: a taxpayer with 20 foreign accounts who failed to file in Year 1 faces one non-willful violation for Year 1, not 20. Bittner applies to non-willful violations only; willful penalties may still be calculated per account per year. Confirm the current IRS enforcement posture on Bittner at IRS.gov.
What are the Streamlined Filing Compliance Procedures and who can use them?
The Streamlined Filing Compliance Procedures are IRS programs for taxpayers who non-willfully failed to file FBARs or report foreign income. The Streamlined Domestic Offshore Procedures (SDOP) apply to U.S. residents and require filing 3 years of amended returns, 6 years of FBARs, and paying a 5% miscellaneous offshore penalty. The Streamlined Foreign Offshore Procedures (SFOP) apply to qualifying non-U.S. residents (must have resided outside the U.S. for at least 1 of the 3 prior calendar years) and impose no penalty. Both require a non-willfulness certification under penalties of perjury. Taxpayers who are already under IRS audit, or whose conduct may be willful, are not eligible. Hedge all program specifics to current IRS.gov guidance.
What happens if a taxpayer who used Streamlined Procedures is later found to be willful?
If the IRS determines that a taxpayer who certified non-willfulness under the Streamlined Procedures was actually willful, the IRS can assert full willful FBAR penalties as if the Streamlined Procedures were never used. The 5% SDOP penalty (or the zero-penalty SFOP treatment) would not apply. The taxpayer also faces potential criminal exposure for the false certification under penalties of perjury. Practitioners must carefully evaluate all facts before recommending the Streamlined Procedures for a client whose willfulness determination is not clearly resolved in favor of non-willfulness.
How has FATCA changed the offshore compliance landscape?
FATCA (IRC 1471-1474) requires foreign financial institutions (FFIs) to report U.S. account holders to the IRS or face 30% withholding on certain U.S.-source payments. The U.S. has entered into intergovernmental agreements (IGAs) with most major financial centers (Switzerland, UK, Germany, Canada, Singapore, Hong Kong, and many others), creating automatic exchange of U.S. account data. The IRS now receives account information from thousands of foreign institutions without making individual treaty requests. Practitioners should assume that unreported foreign accounts in IGA-partner jurisdictions have a high risk of detection and that the era of maintaining undisclosed accounts through foreign banking privacy is effectively over for most U.S. taxpayers. The urgency of voluntary compliance before the IRS identifies the taxpayer through FATCA reporting is substantially greater than at any prior point.
Related Practitioner Guides
The following guides cover international tax reporting obligations and assessment statute issues that commonly arise alongside FBAR and Form 8938 FATCA compliance in the same client engagement.
- IRC 7701(b): Substantial Presence Test: the residency starting date determination that triggers FBAR and FATCA reporting obligations for the first year of U.S. residency.
- IRC 6677: Foreign Trust Reporting Penalties: the parallel penalty regime for Forms 3520 and 3520-A that applies when the foreign account is held inside a foreign trust.
- IRC 1441 and IRC 1442: NRA Withholding, Form 1042, Chapter 3 and Chapter 4: Default 30 percent Chapter 3 withholding, QI regime, treaty documentation, and FATCA coordination.
- IRC 6501 Audit Statute of Limitations Practitioner Guide: covers the base 3-year assessment period, the 6-year omission exception, the unlimited fraud and non-filing exceptions, and the specific SOL extension under IRC 6501(c)(8) triggered by Form 8938 failures -- a mandatory companion to any FBAR/FATCA remediation analysis.
- Form 5471 and Form 5472 Foreign Corporation and Partnership Reporting Practitioner Guide: clients with foreign financial accounts that trigger FBAR and Form 8938 obligations frequently also hold interests in foreign corporations or domestic entities owned by foreign persons, triggering Form 5471 or Form 5472 information return obligations in the same engagement.
- IRC 482 Transfer Pricing Practitioner Guide: multinational clients with both offshore account exposure and related-party cross-border transactions face overlapping compliance obligations; the IRC 482 arm's-length standard and contemporaneous documentation requirements are a companion international tax issue in larger client matters.
- State Income Tax Residency, Domicile, and the 183-Day Rule Practitioner Guide: high-net-worth individuals who assert non-U.S. residency to qualify for the SFOP must also address the state income tax residency question; a federal-level determination that a client was a non-U.S. resident does not automatically resolve the state-level domicile or statutory residency analysis in states like New York.
- Foreign Tax Credit Form 1116 and Form 1118 Practitioner Guide: taxpayers with unreported foreign accounts are typically also earning foreign-source income subject to foreign tax; once the FBAR and Form 8938 compliance is remediated, the foreign tax credit limitation, passive income basket, and OBBBA NCTI basket issues are common follow-on planning questions.
- PFIC rules IRC 1291-1297 excess distribution QEF election mark-to-market Form 8621 guide: foreign accounts often hold foreign fund investments that are PFICs; a client with FBAR and Form 8938 reporting obligations who holds foreign mutual funds or non-U.S. ETFs almost always has a companion Form 8621 filing and PFIC excess distribution, QEF, or mark-to-market analysis in the same engagement.
