FBAR Penalties: The Decision Tree

If you owe FBAR penalties, or think you might, the first question is not “how much” but “which path gets me to compliance with the least damage.” There are five distinct routes: delinquent FBAR submission, streamlined foreign offshore, streamlined domestic offshore, IRS voluntary disclosure, and reasonable cause after assessment. They produce radically different outcomes on the same facts. The wrong route can turn a zero-penalty fix into a six-figure bill, and the right route can take a potential $100,000+ exposure and resolve it for nothing. The decision tree below maps each fact pattern to the path that fits it. If you are not yet penalized and have simply been late, start with whether you need delinquent filing or streamlined. This page is the penalty-side companion.

What are the actual FBAR penalty amounts?

FBAR penalties live in 31 USC 5321(a)(5), not in the Internal Revenue Code. The Bank Secrecy Act, not the tax code, is the source of authority. The penalties break into two tiers.

Non-willful penalties apply when the failure was not intentional. The statutory cap is $10,000 per violation, inflation-adjusted annually. For violations occurring in 2024, the adjusted cap is approximately $16,117. The IRS can assess less. It can also assess nothing, if reasonable cause exists. The penalty is per report (per year), not per account, after the Supreme Court’s 2023 decision in Bittner v. United States (598 U.S. 85). Before Bittner, the IRS routinely assessed per account, so someone with five Canadian bank accounts who missed three years of FBARs faced 15 potential penalties. After Bittner, the same person faces three (one per missed annual report).

Willful penalties apply when the failure was knowing and intentional, or when the person showed reckless disregard for the reporting requirement. The cap is the greater of $100,000 (inflation-adjusted) or 50% of the balance in the account at the time of the violation. The willfulness standard is high, but the IRS has met it in cases involving taxpayers who checked “no” on Schedule B’s foreign-account question while holding foreign accounts, or who actively concealed accounts after being put on notice of the obligation.

There is also a criminal penalty under 31 USC 5322 for willful violations: up to $250,000 and five years imprisonment. Criminal prosecution for FBAR violations is rare and generally reserved for cases involving active concealment, fraud, or large-dollar tax evasion. If you are in an audit and concerned it may be turning criminal, see IRS criminal vs civil investigation: the warning signs.

How do I decide which path to take?

Three variables control the decision. First: has the IRS already contacted you about the missing FBARs (an audit letter, a notice, a penalty assessment)? Second: were you non-willful (you did not know about the requirement, or you knew but made an honest mistake) or willful (you knew and chose not to file, or actively concealed)? Third: did you live in the US or outside it during the years in question?

Your situation	IRS contacted you?	Path
FBARs late, returns filed and correct, income reported	No	Delinquent FBAR submission
FBARs late, returns filed but incomplete (missing foreign income)	No	Streamlined (foreign or domestic, depending on where you lived)
FBARs late, returns never filed	No	Streamlined (foreign or domestic)
FBARs late, any situation, conduct was willful	No	IRS Voluntary Disclosure (formerly OVDP successor)
IRS has already assessed FBAR penalties	Yes	Reasonable cause defense or penalty abatement request
IRS audit is open but penalties not yet assessed	Yes	Cooperate with the audit, assert reasonable cause

The delinquent FBAR submission procedures carry no penalty when the taxpayer is not under civil examination or criminal investigation and the income was properly reported. The streamlined procedures carry a 5% miscellaneous offshore penalty (domestic) or zero penalty (foreign) on the highest aggregate balance. Voluntary disclosure carries a civil fraud penalty of 75% on one year, but provides protection from criminal prosecution.

What is the delinquent FBAR submission route?

The simplest path. You file the late FBARs through FinCEN’s BSA E-Filing System with a reasonable-cause statement explaining why they are late. No amended returns, no formal application, no penalty. The IRS’s Delinquent FBAR Submission Procedures page was taken down in mid-2026, but the underlying standard is unchanged: if you were not willful, you are not under examination or investigation, and the income from the accounts was already reported on your tax returns, you file the late FBARs and move on.

The limitation: it only works when the returns themselves are correct. If you have unreported foreign income, missing Form 8938 filings, or Form 3520 issues, the delinquent route does not fix those problems. For the full mechanics, see late FBARs: delinquent filing or streamlined.

What is the streamlined procedure, and which version do I use?

The IRS Streamlined Filing Compliance Procedures are for taxpayers who were non-willful and need to fix both FBARs and tax returns. There are two versions.

Streamlined Foreign Offshore (SFOP) is for US taxpayers who lived outside the United States during the relevant period (meeting the non-residency requirement). The penalty is zero. You file three years of amended or delinquent returns and six years of FBARs, certify non-willfulness on Form 14653, and the IRS processes the returns with no offshore penalty. For Canadians who are also US citizens or green card holders, this is usually the path: you lived in Canada, not the US.

Streamlined Domestic Offshore (SDOP) is for US taxpayers who lived in the United States. The penalty is 5% of the highest aggregate balance of the unreported foreign financial assets during the six-year FBAR period. You file three years of amended returns and six years of FBARs, certify non-willfulness on Form 14654, and pay the 5% penalty. Five percent sounds modest, but on a $500,000 aggregate balance, it is $25,000.

The non-willfulness certification is the critical document. It must be truthful and specific. A vague statement (“I didn’t know”) is weaker than a detailed narrative explaining why you did not know (for example, you immigrated to the US and no one told you about FBAR obligations, your Canadian accountant handled your affairs and never mentioned US filing, you believed RRSPs were exempt). The IRS can reject a streamlined submission if it determines willfulness, and the certification is made under penalty of perjury.

What if my conduct was willful?

If you knew about the FBAR requirement and deliberately chose not to file, or if you actively concealed foreign accounts, the streamlined procedures are not available to you. The non-willfulness certification would be false, and filing a false certification under penalty of perjury creates a new problem on top of the old one.

The IRS Voluntary Disclosure Practice is the remaining pre-contact option. It provides protection from criminal prosecution in exchange for full disclosure and payment of taxes, interest, and penalties. The civil penalty structure under voluntary disclosure is severe: typically a fraud penalty of 75% of the tax underpayment for the highest year, plus other applicable civil penalties. But compared with the alternative (criminal prosecution, willful FBAR penalties of 50% of the account balance per year, and potential imprisonment), voluntary disclosure is the rational path for someone whose conduct was genuinely willful.

The threshold between “non-willful” and “willful” is not always clear. Checking “no” on Schedule B’s question about foreign accounts while holding them has been treated as evidence of willfulness by courts, but ignorance of the FBAR requirement specifically (as opposed to active concealment) has been treated as non-willful even when the taxpayer should have known. The distinction matters enormously: the difference between the streamlined zero-penalty path and the voluntary disclosure 75%-penalty path can be hundreds of thousands of dollars.

What if the IRS has already assessed penalties?

If you have received a penalty assessment, the pre-contact paths (delinquent, streamlined, voluntary disclosure) are no longer available for the years covered by the assessment. If the penalty is part of a larger tax debt, an Offer in Compromise may reduce the total exposure, but only if the IRS’s collection math supports it. Your options are:

The first step is to review the penalty notice carefully. Check whether the IRS applied the penalty per account or per report. After Bittner, a per-account assessment on a non-willful violation is wrong, and the IRS should reduce it to one penalty per year.

If the penalty was assessed after an examination, you have 30 days from the notice to request an appeal within the IRS (IRS Appeals). If you disagree with the Appeals outcome, you can petition the federal district court (FBAR penalties are not under Tax Court jurisdiction because they arise under the BSA, not the IRC). Reasonable cause is a complete defense to non-willful FBAR penalties (31 USC 5321(a)(5)(B)(ii)): if you can show reasonable cause for the failure and the balance in the account was properly reported, the penalty should be zero.

For cross-border filers, the reasonable-cause argument is often strong: you relied on a Canadian accountant who did not know about US filing obligations, you were told by a professional that your accounts were exempt, or you genuinely did not know you were a US person (common for accidental Americans who learned of their citizenship later in life). Document the reliance and the professional advice.

Does the Bittner decision change my exposure?

Yes, if you have multiple accounts. In Bittner v. United States, 598 U.S. 85 (2023), the Supreme Court held 5-4 that the non-willful FBAR penalty under 31 USC 5321(a)(5)(A) applies per report (one penalty per year), not per account. Before Bittner, the IRS and several circuit courts assessed the penalty per account per year. For someone with ten foreign accounts who missed five years of FBARs, the pre-Bittner exposure was 50 penalties (10 accounts times 5 years times $10,000 each = $500,000). After Bittner, the exposure is 5 penalties (one per year, approximately $80,000 total at the inflation-adjusted rate).

Bittner applies only to non-willful penalties. Willful penalties are assessed per account, and that holding was not disturbed. If you received a pre-Bittner non-willful penalty assessment that was calculated per account and you have not yet paid or settled, raise Bittner in any pending appeal or collection action. If you already paid a per-account penalty, the path to recovery is a refund claim, though the statute of limitations on refund claims limits this.

How does this interact with my Canadian filing?

For Canadians who are also US persons (citizens, green card holders), the FBAR penalty exposure sits alongside a potential Canadian penalty exposure for late-filed T1135 foreign property reports. The CRA has its own penalty structure for late T1135s ($25/day, capped at $2,500 per year for the standard penalty, with a gross negligence penalty of $500/month capped at $12,000). If you are fixing both sides simultaneously, the CRA’s Voluntary Disclosures Program is the Canadian-side companion to the IRS streamlined or voluntary disclosure path.

The coordination problem is real. The IRS streamlined procedures require you to certify non-willfulness. The CRA’s VDP has its own eligibility conditions, including that the disclosure must be voluntary (not prompted by CRA enforcement action) and must be complete. Filing one country’s disclosure can, in some circumstances, trigger information exchange under Article XXVII of the treaty that reaches the other country’s enforcement arm. The sequencing matters.

What should I do next?

Run the three variables: (1) has the IRS contacted you, (2) were you non-willful, and (3) did you live in the US or abroad? The answer maps to exactly one path. Do not start filing until the path is chosen, because entering one program can foreclose another.

If you have Canadian accounts and are also behind on T1135 filings, the two-country coordination adds a layer. See cross-border penalty coordination for the sequencing strategy. Get both sides mapped before moving on either.
