FBAR Penalties: The Decision Tree From 'I Missed It' to the Right Procedure and the Right Number

Short version: What Is the FBAR? Reporting Foreign Bank Accounts

FBAR penalties range from nothing to half the account. Which one applies is decided by a short sequence of questions, and the sequence also decides the procedure. Was every dollar of income from the accounts reported on the returns? If yes, the delinquent FBAR procedure: file, explain, no penalty. If no, was the failure non-willful? If yes, the streamlined program: file, certify, no FBAR penalty (or the domestic 5%). If the failure may have been willful, the Voluntary Disclosure Practice: a willful penalty, negotiated, in exchange for no prosecution. And if the IRS has already made contact, none of the programs applies and the penalty is determined in the examination under the IRS's mitigation guidelines, with reasonable cause as the defence. The tree below runs each branch to its number.

Key takeaways

• The penalties: non-willful, up to an inflation-adjusted amount per violation (about $16,000 for current years), per report rather than per account after the Supreme Court's Bittner decision, and excusable for reasonable cause; willful, the greater of an inflation-adjusted amount (about $160,000) and 50% of the account balance at the time of the violation, per year, with a six-year statute.
• Question 1: was all income from the accounts reported? Yes: Delinquent FBAR Submission Procedures; no penalty. No: continue.
• Question 2: was the conduct non-willful? Yes: streamlined (foreign, no penalty; domestic, 5% miscellaneous penalty in place of FBAR penalties). No or unsure: continue.
• Question 3: is the conduct willful? The Voluntary Disclosure Practice: a willful FBAR penalty (the IRS's practice is 50% of the highest aggregate balance during the disclosure period, which the examiner may reduce) plus the fraud penalty on one year; no criminal referral.
• Question 0 (before all others): has the IRS made contact? An examination or an FBAR-specific letter forecloses the programs; the penalty is determined under the IRM mitigation guidelines in the examination, and reasonable cause is argued.
• The mitigation guidelines (IRM 4.26.16) scale penalties to account size and conduct; examiners have discretion, and in most non-willful examinations one penalty per year (or one for all years) is the outcome.

The penalties

Non-willful. The statute provides a penalty of up to $10,000 (inflation-adjusted to about $16,000) per violation; the Supreme Court held in Bittner (2023) that a violation is the failure to file a report, so the penalty is per FBAR per year, not per account. Reasonable cause is a complete defence if the amount of the transaction or the balance was properly reported (the statute's own condition). The IRS's mitigation guidelines suggest lower amounts for small accounts and for first offences, and examiners frequently assess a single non-willful penalty for all years.

Willful. The greater of $100,000 (adjusted to about $160,000) and 50% of the balance in the account at the time of the violation, per year. Courts have upheld cumulative willful penalties exceeding the account's total value across years. Willfulness includes reckless disregard and willful blindness; a prior return answering the Schedule B question "No" is the fact most often relied on.

Statute. Six years from the FBAR's due date for assessment; the IRS assesses through FinCEN's authority; collection through a civil action within two years of assessment.

Question 0: has the IRS made contact?

An open civil examination of any year, a criminal investigation, or an IRS letter specifically about the foreign accounts or the FBARs takes the taxpayer outside all three programs. The FBAR question is then worked in the examination: the examiner determines willfulness and applies the mitigation guidelines; the taxpayer argues reasonable cause (for non-willful) or contests willfulness; disagreements go to Appeals and then to litigation in district court or the Court of Federal Claims (FBAR penalties are not Tax Court matters). A FATCA-driven IRS letter is contact; a bank's FATCA questionnaire is not.

Question 1: was all income reported?

For each account on the missed FBARs: did the income (interest, dividends, gains, and for a TFSA its earnings) appear on the US returns for those years? An RRSP with the treaty deferral counts as reported. If yes for every account, the Delinquent FBAR Submission Procedures apply: file the six FBARs electronically with "Other" and an explanation; the IRS will not impose a penalty. No return is amended. This is the branch for the taxpayer who filed complete returns and never heard of the FBAR.

If any account's income was omitted, the delinquent FBAR procedure is unavailable (its condition fails), and the FBARs go into a program with the amended returns.

Question 2: non-willful?

Non-willful conduct (negligence, inadvertence, mistake, good faith misunderstanding) qualifies for the streamlined procedures if the other conditions (residency track, filed returns for SDOP, no contact) are met. The FBARs are filed as part of the package; the foreign track imposes no FBAR penalty; the domestic track replaces FBAR and information-return penalties with the 5% miscellaneous offshore penalty on the unreported assets' highest year-end value. The certification on Form 14653/14654 states non-willfulness under penalties of perjury.

Question 3: willful?

Where the facts show or risk showing willfulness (a prior "No" that cannot be explained, advice ignored, nominees, funds moved), the streamlined certification cannot be signed and the Voluntary Disclosure Practice is the route. The taxpayer requests preclearance on Form 14457, then discloses; the examination covers six years; the IRS's stated practice for the FBAR penalty in a VDP case is a willful penalty of 50% of the highest aggregate account balance during the disclosure period, assessed for one year, with examiner discretion to reduce it for cooperation; under the practice's current published terms the income-tax penalties are a 20% accuracy-related penalty on each amended year and failure-to-file penalties on delinquent years, with the IRS retaining authority to assert the civil fraud penalty in egregious cases. No criminal referral.

Reasonable cause in an examination

For a non-willful failure examined outside the programs, the statutory reasonable-cause exception applies if the taxpayer shows ordinary business care and prudence: reliance on a competent preparer who was given the account information and did not raise the FBAR; a good faith belief, reasonably held, that the account was not reportable; circumstances beyond the taxpayer's control. The IRM directs examiners to consider it before asserting the non-willful penalty. Where the taxpayer's income was reported and the omission was the form alone, examiners often accept reasonable cause.

Worked example

Four US citizens in Canada, each with six unfiled FBARs on a $300,000 aggregate:

• A filed complete 1040s every year (income reported; RRSP deferred). No IRS contact. Question 1: yes. Delinquent FBAR procedure; six FBARs; no penalty.
• B never filed any US return; did not know she was required to. Question 1: no (no returns at all). Question 2: non-willful. Streamlined foreign; six FBARs in the package; no penalty.
• C filed 1040s for years with a US preparer, answered "No" on Schedule B himself, and was told by a colleague in 2019 that Canadian accounts had to be reported. Question 2: cannot certify non-willfulness. Question 3: VDP; willful penalty negotiated from 50% of $300,000; fraud penalty on one year; no prosecution.
• D received an IRS letter in June referencing FATCA data on her Canadian accounts. Question 0: contact made. No program. Files the returns and FBARs in response; argues reasonable cause (a preparer who never asked; income reported in Canada); the examiner applies the mitigation guidelines; a single non-willful penalty for the years, or none.

The IRM provides that "for each non-willful violation... a penalty may be imposed up to the $10,000 penalty amount" (inflation-adjusted to $16,536 for penalties assessed on or after January 17, 2025) and that a "willful FBAR violation may be imposed up to the greater of the $100,000 penalty amount... adjusted for inflation... or 50% of the amount in the account" ($165,353 for 2025); the Supreme Court held in Bittner v. United States (2023) that the non-willful penalty applies per report, not per account. — Internal Revenue Service, IRM 4.26.16, Report of Foreign Bank and Financial Accounts (FBAR), https://www.irs.gov/irm/part4/irm_04-026-016

The IRS states that it "will not impose a penalty for the failure to file the delinquent FBARs if you properly reported on your U.S. tax returns, and paid all tax on, the income from the foreign financial accounts reported on the delinquent FBARs, and you have not previously been contacted regarding an income tax examination or a request for delinquent returns for the years for which the delinquent FBARs are submitted." — Internal Revenue Service, Delinquent FBAR Submission Procedures, https://www.irs.gov/individuals/international-taxpayers/delinquent-fbar-submission-procedures

The IRS states that "the disclosure period generally includes the most recent six years," that a taxpayer requests preclearance on "Form 14457, Voluntary Disclosure Practice Preclearance Request and Application," and that "for amended returns, a 20 percent accuracy-related penalty applies to each year," with failure-to-file penalties on delinquent returns and per-year FBAR penalties "subject to annual inflation adjustments." — Internal Revenue Service, IRS Criminal Investigation Voluntary Disclosure Practice, https://www.irs.gov/compliance/criminal-investigation/irs-criminal-investigation-voluntary-disclosure-practice

Practitioner note

The tree has four questions and the first one is whether the IRS has already written, because every good branch closes on contact. After that it is income reported (no penalty), non-willful (streamlined), or willful (VDP), and the number follows the branch. We run a client's facts through it on the first call, because the answer decides whether we are filing six forms with an explanation or negotiating half an account.
