Quick Answer
Non-willful FBAR violations involve four key determinations: (1) what "non-willful" means — absence of willfulness but not necessarily absence of negligence; (2) penalty amount — up to $10,000 per report per year after Bittner (2023); (3) defenses — reasonable cause based on good faith; and (4) resolution paths — streamlined filing compliance procedures or delinquent FBAR submission. The short version is that the Supreme Court's 2023 Bittner decision dramatically reduced non-willful exposure from per-account to per-report. In our experience, most taxpayers who missed FBAR were genuinely non-willful; penalty mitigation is almost always possible with proper documentation.1

Quick Reference

1. What Non-Willful Means
Absence of willfulness — not specifically knowing or recklessly disregarding.
If this is you: Missed FBARs without knowledge of filing obligation, or under mistaken belief compliance satisfied. Not willful if genuinely unaware. Documentation of state of mind matters.
Non-Willful Strategy
- Document state of knowledge.
- Preserve evidence of good faith.
- Document reliance on professionals (if any).
- Assess whether reasonable cause applies.
- Select appropriate resolution path.
2. Penalty Amount Post-Bittner
Up to $10,000 per report per year — Bittner 2023.
If this is you: Prior-year penalties per account reversed by Bittner. Current penalty up to $10K per report per year, not per account. Significantly reduced exposure for multi-account taxpayers.
3. Reasonable Cause Defense
Good faith + reasonable reliance on professional advice or facts.
If this is you: Relied on CPA / attorney who didn't advise on FBAR. Relied on foreign tax preparer. Foreign account holder unaware of U.S. reporting. Document reasonable cause facts.
4. Resolution Paths
Streamlined or delinquent FBAR submission procedure.
If this is you: Prior-year non-compliance. Streamlined: 6 years FBAR + 3 years 1040 amendment + 5% (domestic) or 0% (foreign) penalty. Delinquent: if no unreported income, file with explanation; often no penalty.

Frequently Asked Questions
What is non-willful FBAR?
Missed FBAR without willfulness — absence of specific intent and absence of reckless disregard. Non-willful filer can still be negligent but not willful. Standard different from criminal willfulness.
What changed with Bittner?
Supreme Court held non-willful penalty is per-report not per-account. Drastically reduced exposure for multi-account taxpayers. $10K per report per year rather than per account.
What qualifies for streamlined?
Non-willful delinquency. U.S. resident (domestic, 5% penalty) or non-U.S. resident (foreign, 0% penalty). 6 FBAR years + 3 amended returns. No prior IRS contact typically.
What is delinquent FBAR procedure?
Alternative to streamlined for non-willful filers with no unreported income. Simply file late FBARs with explanation. Often no penalty if truly non-willful and no income issue.
Can penalties be abated?
Yes for reasonable cause. Good faith + reasonable reliance typically succeeds. Document facts thoroughly.
What is reasonable cause?
Good-faith belief compliance satisfied, reliance on competent professional, lack of knowledge with prompt correction when discovered. Facts-and-circumstances determination.
Does professional reliance help?
Yes if reliance was reasonable and advice was on point. Did preparer know about foreign accounts? Were they competent on international? Facts matter.
What if I didn't know?
Ignorance not automatic defense but supports non-willful. Immigrant unaware of U.S. worldwide reporting — common fact pattern. Document learning path.
Do I need streamlined if low dollars?
Delinquent FBAR procedure may suffice if no unreported income. Streamlined required if unreported income. Cost / benefit analysis.
What's the cost of streamlined?
Domestic: 5% of highest aggregate balance. Foreign: 0% penalty. Plus professional fees. Tax and interest on unreported income separate.
Can I do it myself?
Possible but not advisable. Willfulness determination consequential. Professional representation typically recovers fees through better outcomes.
Does Bittner apply to past years?
Yes for unresolved cases. Prior assessments may be recomputed. Refund claims possible in some cases.
Is attorney-client privilege important?
Very. Willfulness analysis benefits from privileged communication. CPA privilege narrower. Attorney engagement creates stronger protection.
