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.

FBAR (FinCEN 114) violations fall into two penalty regimes that differ by orders of magnitude:
The line between the two is often the single most important factual question in any FBAR enforcement case.
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.
The IRS and courts apply a three-tier framework:
Courts have found willfulness where:
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.
For non-willful taxpayers, the Streamlined Filing Compliance Procedures offer a structured path back to compliance:
Both require a sworn certification of non-willful conduct. False certification is itself a felony.
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:
The choice is a strategic decision that requires US tax counsel.
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.
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.
