How FBAR penalties actually work in 2026: the willful vs non-willful distinction, recent Supreme Court guidance, the Streamlined Filing Compliance Procedures, and what Italians with US accounts should do if they discover an omission.

The two penalty regimes FBAR (FinCEN 114) violations fall into two penalty regimes that differ by orders of magnitude: - Non-willful: civil penalty up to $10,000 per violation, adjusted annually for inflation (currently ~$16,536 per violation per IRS 2025 figures). - Willful: civil penalty up to the greater of $100,000 or 50% of the maximum account balance, per account, per year. Plus potential criminal exposure under 31 U.S.C. §5322 (fines up to $250,000 and imprisonment up to 5 years; if combined with other crimes, up to $500,000 and 10 years). The line between the two is often the single most important factual question in any FBAR enforcement case. Bittner v. United States (2023) — what changed In Bittner v. United States (2023), the US Supreme Court ruled that the non-willful FBAR penalty applies per FORM, not per ACCOUNT. This was a major taxpayer victory. Before Bittner, the IRS treated each unreported account as a separate violation. An Italian with 5 unreported accounts over 6 years faced 30 penalty exposures. After Bittner, the same fact pattern is 6 violations (one per annual form). The willful penalty, however, remains per account, per year. So a willfulness finding still produces catastrophic exposure. How "willful" is defined The IRS and courts apply a three-tier framework: - Knowing violation: actual knowledge of the FBAR requirement and intentional non-filing. - Willful blindness: subjective awareness of a high probability that the requirement applied, combined with deliberate avoidance of confirming it. - Reckless disregard: conduct that creates an unjustifiable risk of legal violation, where a reasonable person would have inquired. Courts have found willfulness where: - The taxpayer signed Schedule B of Form 1040 answering "no" to the foreign account question while in fact having one. - The taxpayer discussed the accounts with US tax advisors but failed to follow disclosure recommendations. - Account statements were sent to a non-US address to avoid US scrutiny. - Wire transfer patterns suggest deliberate concealment. What Italians typically face Two recurring profiles: Profile A — Italian who became a US tax resident. Held Italian bank/brokerage accounts before moving to the US. Did not realize FBAR applied to US tax residents (not just citizens). Discovered the obligation after 2-5 years. Typically a non-willful case if the omission is consistent with genuine misunderstanding. Profile B — Italian-American dual citizen living in Italy. US citizen by birth, never lived in the US, holds Italian accounts. Often discovers FBAR through bank questionnaires or FATCA notices. The IRS has historically been more lenient with this profile if disclosure is voluntary and there is no income tax avoidance. The Streamlined Filing Compliance Procedures For non-willful taxpayers, the Streamlined Filing Compliance Procedures offer a structured path back to compliance: - Streamlined Foreign Offshore Procedures (SFOP): for taxpayers residing outside the US (most Italian-Americans in Italy). Filing of 3 years of amended returns and 6 years of FBARs. No FBAR penalty, no failure-to-file penalty, no accuracy-related penalty. Tax and interest only. - Streamlined Domestic Offshore Procedures (SDOP): for US-resident taxpayers. Same filing, but with a 5% miscellaneous offshore penalty on the highest aggregate balance. Both require a sworn certification of non-willful conduct. False certification is itself a felony. When NOT to use Streamlined If there is any meaningful risk of willfulness, Streamlined is the wrong vehicle. A failed certification can convert a civil case into a criminal one. In willful or borderline cases, options include: - Voluntary Disclosure Practice (VDP): covers willful conduct, requires substantial penalty payment but provides protection from criminal referral. - Quiet disclosure: filing amended returns and missing FBARs without entering any program. Higher risk, but sometimes appropriate for very low exposure. - Doing nothing: rarely the right answer once the omission is known, but the analysis is fact-specific. The choice is a strategic decision that requires US tax counsel. Italian-side coordination For Italian residents who are also US persons, FBAR coordination must align with Quadro RW. Inconsistent reporting between the two regimes is itself an audit trigger. Where Quadro RW was correctly filed but FBAR was omitted, the Streamlined certification is generally easier to support. Recent enforcement trends - The IRS has expanded use of FATCA data to identify non-filers. - Large Italian banks routinely report US-person account holders to the US. - Penalty recovery has increasingly been pursued via federal civil suits for collection abroad. - Italy-US Mutual Collection Assistance under the Treaty enables cross-border enforcement. Practical example — Streamlined success Italian-American dual citizen, 52, lived in Milan since age 5. Discovered FBAR obligation through Italian bank's FATCA questionnaire in 2025. Held two Italian accounts (~€80,000 average). Income was salary subject to Italian tax (foreign tax credit fully eliminates US tax). Under SFOP: filed 3 years of amended Forms 1040 (no US tax due after FTC), 6 years of FBARs. Zero penalty. Compliance restored, FATCA certification clean for future years. [LAST UPDATED: May 2026]
After Bittner v. United States (2023), the non-willful penalty is capped at ~$16,536 (2025-adjusted) per FORM per year, not per account. A 6-year omission is a maximum exposure of ~$99,000, not 6 × accounts × years.
Up to the greater of $100,000 or 50% of the maximum account balance, per account, per year. Plus potential criminal exposure of up to 5 years imprisonment under 31 U.S.C. §5322.
Yes if (a) you reside outside the US for at least 1 of the past 3 years, (b) your conduct was non-willful, and (c) you can certify under penalty of perjury. SFOP carries no FBAR penalty.
This is called a quiet disclosure. It is technically possible but carries higher audit risk. Whether appropriate depends on the exposure size and willfulness analysis.
Likely yes. FATCA requires Italian banks to report US-person account holders. Many Italian taxpayers discover their omission through their Italian bank's FATCA questionnaire.
