FBAR penalties: what the courts have decided

On most legal questions, the federal courts of appeals now agree. The real fights are over the facts of willfulness — and one constitutional question that splits the circuits.

By Tongzhou Li, Attorney & CPA, former IRS Appeals Officer · Updated November 7, 2026

What is an FBAR?

The FBAR — the Report of Foreign Bank and Financial Accounts — is a yearly report of your accounts outside the United States. It goes to the Treasury Department’s Financial Crimes Enforcement Network, separately from your tax return, and the IRS enforces it.

You must file if you are a U.S. person — a citizen, a resident, or a U.S. company, trust or estate — with a financial interest in, or signature or other authority over, foreign financial accounts whose combined value exceeded $10,000 at any time during the year (31 C.F.R. §§ 1010.350, 1010.306). The report is due April 15, with an automatic extension to October 15.

Non-willful penalty
Up to $10,000 per report, adjusted for inflation ($16,536 for penalties assessed on or after January 17, 2025). There is no penalty if the violation was due to reasonable cause and the account balance was properly reported (31 U.S.C. § 5321(a)(5)(B)).
Willful penalty
Up to the greater of $100,000 (adjusted to $165,353) or 50% of the account’s balance at the time of the violation — per account, per year (§ 5321(a)(5)(C)–(D)). Reckless conduct counts as willful.
Time limit
The IRS has six years from the violation to assess a penalty (§ 5321(b)(1)). It then sues in federal district court to collect; a taxpayer who pays can instead sue for a refund in the Court of Federal Claims.
Criminal statutes
31 U.S.C. § 5322: up to 5 years in prison for a willful violation, or up to 10 years if it occurs while violating another federal law or as part of a pattern of illegal activity involving more than $100,000 in a 12-month period. Related tax charges include IRC §§ 7201 and 7206(1).

The settled rules

The bubbles list the thirteen federal courts of appeals; the map below them shows the same circuits by region. Blue circuits have decided the question this way; gray circuits have not ruled, and district courts there generally follow the circuits that have.

Reckless conduct is “willful.”

A taxpayer who recklessly disregards an obvious risk that the FBAR is missing or wrong is treated as willful — knowledge is not required. Recklessness is judged objectively, following the Supreme Court’s Safeco test. Every court of appeals to decide the question agrees.

  • United States v. Reyes, No. 24-2333 (2d Cir. Jan. 7, 2026)
  • Bedrosian v. U.S. Dep't of the Treasury, 42 F.4th 174 (3d Cir. 2022)
  • United States v. Horowitz, 978 F.3d 80 (4th Cir. 2020)
  • United States v. Kelly, 92 F.4th 598 (6th Cir. 2024)
  • United States v. Hughes, 113 F.4th 1158 (9th Cir. 2024)
  • United States v. Rum, 995 F.3d 882 (11th Cir. 2021)
  • Norman v. United States, 942 F.3d 1111 (Fed. Cir. 2019)
Decided this way: Second Circuit, Third Circuit, Fourth Circuit, Sixth Circuit, Ninth Circuit, Eleventh Circuit, Federal Circuit1234567891011DCFederal Cir.

The willful penalty can reach 50% of the balance.

Since 2004 the statute allows the greater of $100,000 or 50% of the account balance per violation. A 1987 regulation still said $100,000; two district courts applied it in 2018 (Colliot and Wahdan), but every court of appeals since has held the statute controls.

  • United States v. Kahn, 5 F.4th 167 (2d Cir. 2021)
  • United States v. Horowitz, 978 F.3d 80 (4th Cir. 2020)
  • United States v. Rum, 995 F.3d 882 (11th Cir. 2021)
  • Norman v. United States, 942 F.3d 1111 (Fed. Cir. 2019)
Decided this way: Second Circuit, Fourth Circuit, Eleventh Circuit, Federal Circuit1234567891011DCFederal Cir.

Non-willful: one penalty per report, not per account.

The non-willful penalty is capped at $10,000 per late or inaccurate FBAR, however many accounts it should have listed. The Supreme Court settled this for every circuit in 2023, reversing a Fifth Circuit decision that allowed $2.72 million in penalties for 272 accounts.

  • Bittner v. United States, 598 U.S. 85 (2023)
  • United States v. Boyd, 991 F.3d 1077 (9th Cir. 2021) (same rule, earlier)
Binding in every circuit1234567891011DCFederal Cir.

Burden of proof: preponderance, in practice.

No court of appeals has squarely decided whether the government must prove willfulness by a preponderance of the evidence or by clear and convincing evidence. District courts apply preponderance, and the Third Circuit applies it to the facts behind the maximum penalty.

  • Bedrosian v. U.S. Dep't of the Treasury, 42 F.4th 174 (3d Cir. 2022)
Decided this way: Third Circuit1234567891011DCFederal Cir.

The split: is the FBAR penalty a “fine”?

The cases ↓

If it is, the Eighth Amendment bars penalties that are grossly disproportionate to the violation. The First and Eleventh Circuits disagree, and the Fourth has assumed the answer is yes without deciding. The Supreme Court declined to take up the question in 2023.

How it works

Thirteen courts of appeals

An FBAR penalty suit is heard where the taxpayer lives, and appeals go to that region’s circuit. Taxpayers who pay and sue for a refund in the Court of Federal Claims appeal to the Federal Circuit instead.

As of this writing, a challenge on this question is pending in the Ninth Circuit, which covers California.

The leading case in each circuit

↑ Back to the map

For each court of appeals, the most-cited published decision on the civil FBAR penalty, briefed: the facts, what the court held, how it came out, and the key sentence. Four circuits have not yet decided a civil FBAR case. The Fifth Circuit’s entry is the Supreme Court decision that reversed it.

First Circuit

Maine, Massachusetts, New Hampshire, Rhode Island

United States v. Toth

33 F.4th 1 (1st Cir. 2022)

Bottom lineThe willful FBAR penalty is not a “fine,” so it cannot be attacked as excessive under the Eighth Amendment. The Eleventh Circuit holds the opposite.

“a civil penalty imposed under § 5321(a)(5)(C)-(D) is not a ‘fine’ and as such the Excessive Fines Clause of the Eighth Amendment does not apply to it.”

33 F.4th 1
Facts
Monica Toth, a U.S. citizen, had held a UBS account in Switzerland since 1999 and filed her first FBAR in 2010. After an audit, the IRS found her 2007 violation willful and assessed $2,173,703 — half the account’s value. Representing herself, she repeatedly missed discovery deadlines, and the court treated willfulness as established as a sanction.
Holdings
  • A willful penalty under § 5321(a)(5)(C)–(D) is not a “fine,” so the Excessive Fines Clause does not apply. The court saw the penalty as remedial: it addresses lost revenue and the cost of investigating hidden accounts.
  • The 1987 regulation’s $100,000 cap was superseded when Congress raised the maximum in 2004.
  • The discovery sanction establishing willfulness was within the trial court’s discretion.
  • Her due process challenge to the amount was waived.
Result
Affirmed, including $826,469.56 in late-payment penalties and $137,925.92 in interest.

Second Circuit

Connecticut, New York, Vermont

United States v. Kahn

5 F.4th 167 (2d Cir. 2021)

Bottom lineThe willful penalty is capped by the statute — 50% of the balance — not by the old $100,000 regulation. Here the government collected it from the estate of a taxpayer who died after the assessment.

“the penalty limitation provided in the 1987 Regulation—which reflected the penalty provision in the 1986 version of the statute—was superseded by the 2004 amendment to the statute increasing the penalty maximum”

5 F.4th 167
Facts
Harold Kahn willfully failed to file his 2008 FBAR, due June 30, 2009, for two Credit Suisse accounts in Switzerland holding a combined $8,529,456. The IRS assessed $4,264,728, half the balance. Kahn died without paying, and the government sued his estate.
Holdings
  • Congress’s 2004 amendment superseded the 1987 regulation’s $100,000 cap, which had simply tracked the older statute.
  • The rule of lenity did not apply because the statute’s “greater of” formula is not ambiguous.
  • A dissent would have held Treasury bound by its own regulation until it was changed.
Result
Affirmed: $4,264,728 plus statutory additions and interest.

Third Circuit

Delaware, New Jersey, Pennsylvania

Bedrosian v. United States

912 F.3d 144 (3d Cir. 2018)

Bottom lineThis case set the test most courts now use: reckless conduct is willful if you clearly ought to have known of a grave risk your FBAR was wrong and could easily have checked.

“the standard of willfulness under the FBAR statute refers to the civil willfulness standard, which includes both knowing and reckless conduct.”

912 F.3d at 153–54
Facts
Arthur Bedrosian had kept a Swiss account since the 1970s, later at UBS. His 2007 FBAR listed one UBS account worth about $240,000 but left off a second worth about $2 million. In 2015 the IRS assessed $975,789 — half the omitted account. He paid part, sued for a refund, and the trial court found he was not willful.
Holdings
  • Civil FBAR willfulness covers both knowing and reckless violations.
  • Recklessness is objective: conduct creating an unjustifiably high risk of harm that is known or so obvious it should be known (the Supreme Court’s Safeco test).
  • A trial judge’s willfulness finding is reviewed for clear error, but legal errors in applying the standard are corrected.
  • The Federal Circuit does not have exclusive jurisdiction over these appeals.
Result
Vacated and sent back, because the appeals court could not tell whether the trial court used the objective standard.

Later treatmentUnited States v. Collins (2022) limits Bedrosian’s jurisdiction discussion: it did not hold that FBAR penalties are “taxes” for debt-collection purposes.

Also important in this circuit

  • Bedrosian v. IRS, 42 F.4th 174 (3d Cir. 2022) — After the case was sent back, the trial court found Bedrosian willful — his accountant had warned him, and the FBAR he signed understated his balance — and the Third Circuit affirmed.

Fourth Circuit

Maryland, North Carolina, South Carolina, Virginia, West Virginia

United States v. Horowitz

978 F.3d 80 (4th Cir. 2020)

Bottom lineA couple who kept most of their savings in Switzerland, never asked their CPA, and signed returns answering “no” to the foreign-account question were reckless — and so willful.

“a ‘willful violation’ of the FBAR reporting requirement includes both knowing and reckless violations.”

978 F.3d at 88
Facts
Peter and Susan Horowitz, U.S. citizens who had worked in Saudi Arabia, filed no FBARs from 1988 through 2008 for their Swiss accounts. Their UBS account held about $1.6 million by 2001, and in 2008 Peter moved nearly $2 million to another Swiss bank. In 2014 the IRS assessed $247,030 against each spouse for each of 2007 and 2008.
Holdings
  • For the civil penalty, a willful violation includes both knowing and reckless violations, even though a criminal conviction requires knowledge of the law.
  • Their conduct was objectively reckless: they knew of a large interest-bearing foreign account, never mentioned it to their accountant, used numbered-account and hold-mail services, and signed returns saying they had no foreign accounts.
  • The 1987 regulation’s $100,000 cap was abrogated by the 2004 amendment.
  • Deleting the assessment date from an IRS database did not reverse the timely assessments, so the suit was timely.
Result
Affirmed: $654,568 against Peter and $327,284 against Susan (2007 only), with interest and penalties.

Also important in this circuit

  • United States v. Rund, No. 24-1958 (4th Cir. Sept. 4, 2026) — More than a dozen unreported accounts in Hong Kong, Switzerland and elsewhere; a $2,915,663 penalty. Willful as a matter of law; even assuming the Excessive Fines Clause applies, the total was not excessive.

Fifth Circuit

Louisiana, Mississippi, Texas

Bittner v. United States

598 U.S. 85 (2023)

Supreme Court

The Supreme Court reversed the Fifth Circuit (United States v. Bittner, 19 F.4th 734 (2021)). The ruling binds every circuit.

Bottom lineThe non-willful penalty is capped at $10,000 per FBAR, not per account. For Mr. Bittner, five late reports meant a maximum of $50,000 instead of $2.72 million.

“Best read, the BSA treats the failure to file a legally compliant report as one violation carrying a maximum penalty of $10,000, not a cascade of such penalties calculated on a per-account basis.”

598 U.S. 85
Facts
Alexandru Bittner, a dual U.S.-Romanian citizen, learned of the FBAR requirement after returning to the United States in 2011. He filed late reports for 2007 through 2011, later corrected to list 272 accounts. The government did not claim he was willful, but assessed $10,000 per account — $2.72 million.
Holdings
  • The reporting duty is to file a complete, accurate report. Failing to do so is one violation, however many accounts the report should have listed.
  • The non-willful penalty is tied to “violations,” not accounts. Congress used per-account language only for certain willful penalties and for the reasonable-cause exception — and not here.
Result
Reversed and sent back, 5–4.

Sixth Circuit

Kentucky, Michigan, Ohio, Tennessee

United States v. Kelly

92 F.4th 598 (6th Cir. 2024)

Bottom lineRecklessness is willful. Entering the IRS voluntary disclosure program does not undo willfulness if you are later removed for not cooperating.

“Based on the above authorities, we hold that, for purposes of an FBAR civil penalty, a willful violation of the FBAR reporting requirements includes both knowing and reckless violations.”

92 F.4th at 603
Facts
James Kelly closed his U.S. accounts in 2008 and kept about $1.5 million in a numbered, interest-bearing Swiss account with mail held at the bank. When the bank blocked the account over U.S. tax compliance, he moved the money to Liechtenstein. He entered the IRS voluntary disclosure program but was removed for noncompliance; the IRS proposed $769,126 in penalties for 2013 through 2015.
Holdings
  • Following the Supreme Court’s Safeco decision, a willful violation includes both knowing and reckless violations.
  • Recklessness is shown when the person clearly ought to have known of a grave risk that an accurate FBAR was not being filed and could easily have found out.
  • Kelly’s concealment — a numbered account, held mail, avoiding U.S. investments that would have required tax forms — and his continued failure to file made him at least reckless.
  • Participating in the voluntary disclosure program did not negate willfulness.
Result
Summary judgment for the government affirmed.

Ninth Circuit

Alaska, Arizona, California, Hawaii, Idaho, Montana, Nevada, Oregon, Washington

United States v. Boyd

991 F.3d 1077 (9th Cir. 2021)

Bottom lineOne late but accurate FBAR is one non-willful violation, capped at $10,000. The Supreme Court adopted the same rule nationwide in Bittner.

“Boyd committed a single non-willful violation—the failure to timely file the FBAR.”

991 F.3d 1077
Facts
Jane Boyd, a U.S. citizen, had fourteen accounts in the United Kingdom, which grew after she deposited an inheritance, and did not report them or their income for 2010. Through the IRS voluntary disclosure program she filed an accurate 2010 FBAR in 2012, then opted out. The IRS treated each unreported account as a separate non-willful violation and assessed $47,279.
Holdings
  • Filing one accurate FBAR late is a single violation — the failure to file on time — regardless of the number of accounts.
  • Even if the statute were ambiguous, tax penalty provisions are construed strictly against the government.
  • A dissent would have counted one violation per account.
Result
Reversed and sent back; the maximum penalty is $10,000.

Later treatmentUnited States v. Paulson (2023) limits Boyd’s strict-construction reasoning to tax provisions that impose penalties.

Also important in this circuit

  • United States v. Hughes, 113 F.4th 1158 (9th Cir. 2024) — Joined every other circuit: willful includes knowing and reckless violations. The sole owner of a New Zealand winery and wine bar who filed no FBARs for 2010–2013 owed $238,125.19.

Eleventh Circuit

Alabama, Florida, Georgia

United States v. Schwarzbaum

127 F.4th 259 (11th Cir. 2025)

Bottom lineThe willful FBAR penalty is a “fine” subject to the Excessive Fines Clause, judged account by account. A $100,000 penalty on an account that never held $16,000 is unconstitutional.

“We hold, therefore, that the FBAR penalty is a fine subject to the Eighth Amendment’s Excessive Fines Clause.”

127 F.4th 259
Facts
Isac Schwarzbaum, a wealthy naturalized citizen, held accounts in Switzerland and Costa Rica and did not report them for 2007 through 2009, though he had read the FBAR instructions and used accountants. The trial court found him reckless, and so willful. The IRS’s recalculated penalty was $13,521,328; the judgment was $12,555,813.
Holdings
  • The FBAR penalty is punitive at least in part — it is not tied to the government’s costs and is meant to deter — so it is a fine subject to the Eighth Amendment.
  • Applied account by account, three $100,000 penalties on an account holding about $10,000 to $12,000 on the assessment dates were grossly disproportional. The penalties on the larger accounts stood.
  • The government may seek less than the full assessed penalty.
Result
Sent back for entry of a $12,255,813 judgment ($300,000 less), plus late fees and interest. This opinion replaces the court’s 2024 opinion in the same appeal.

Also important in this circuit

  • United States v. Rum, 995 F.3d 882 (11th Cir. 2021) — Willfulness includes reckless disregard of a known or obvious risk; the statute, not the 1987 regulation, sets the maximum. Rum had opened a numbered UBS account with $1.1 million to keep money from potential judgment creditors.
  • United States v. Schwarzbaum, 24 F.4th 1355 (11th Cir. 2022) — The first appeal: upheld the finding that his reckless failure to file was willful, and sent the penalty back to the IRS because it had used the wrong account balances.

D.C. Circuit

District of Columbia

No published decision of this court of appeals on the civil FBAR penalty yet. Courts here are bound by Bittner on non-willful penalties and generally follow the other circuits’ uniform rule that reckless conduct is willful.

Federal Circuit

Nationwide: appeals from Court of Federal Claims refund suits

Norman v. United States

942 F.3d 1111 (Fed. Cir. 2019)

Bottom lineSigning a return that says “no foreign accounts” supports willfulness, and not reading the return is no excuse. (Refund suits in the Court of Federal Claims follow the Federal Circuit.)

“willfulness in the context of § 5321(a)(5)(C) includes recklessness.”

942 F.3d at 1115
Facts
Mindy Norman, a schoolteacher, opened a numbered UBS account in Switzerland in 1999; it held roughly $1.5 to $2.5 million from 2001 to 2008. She filed no FBAR for 2007, and the IRS assessed a willful penalty of $803,530, which the Court of Federal Claims upheld.
Holdings
  • Willfulness for the civil penalty includes recklessness.
  • She signed, under penalty of perjury, a 2007 return denying any foreign account after her accountant’s questionnaire asked about one. She had a numbered account, barred U.S. investments, took a withdrawal in cash, and made false statements to the IRS in the audit.
  • A taxpayer who signs a return is charged with knowing its contents; not reading it supports recklessness.
  • The 1987 regulation’s $100,000 cap is void because it conflicts with the 2004 statute.
Result
Affirmed.

  • Kimble v. United States, 991 F.3d 1238 (Fed. Cir. 2021) — A secret, numbered UBS account opened by her parents, who made her a joint owner, and never mentioned to her CPA; she withdrew from the voluntary disclosure program and was assessed $697,299, half the account. Willful, and the 50% penalty was within the IRS’s discretion.

Case research checked against the court opinions, as of November 7, 2026.

Willfulness, case by case

↑ Back to the map

Willfulness is decided on the facts. Across the 23 civil cases below where a court found (or the parties stipulated) willfulness:

  • 19 involved active concealment — numbered or hold-mail accounts, nominees or shell entities, cash withdrawals, or moving money after the UBS disclosures.
  • 12 kept the accounts from their return preparer or a tax organizer.
  • 12 signed returns answering “no” to the foreign-account question (several opinions do not say).
  • Telling the CPA is not a complete defense: in Schwarzbaum the CPAs knew of the accounts and gave wrong advice, and willfulness was still found.

About this survey

  • Covers decisions of the Supreme Court and the thirteen federal courts of appeals on the civil FBAR penalty (31 U.S.C. § 5321(a)(5)), plus selected district court and Court of Federal Claims cases, as of October 31, 2026.
  • Facts come from the courts’ opinions.
  • Unpublished decisions (such as Williams and Bussell) are not binding precedent but are included for their facts.

General information only. This survey is not legal or tax advice and does not create an attorney-client relationship. Every case turns on its own facts. Facing an FBAR penalty or an unreported foreign account? See how I help or request a consultation.
