What Non-Willful Really Means: The IRS Standard and Evidence

Non-willful conduct, in the IRS's words, is conduct due to negligence, inadvertence, or mistake, or a good-faith misunderstanding of what the law requires. Willfulness is broader than most people assume: for civil FBAR penalties, federal appeals courts have held that it covers not only knowing violations but also reckless disregard, and the IRS treats deliberately avoiding knowledge ("willful blindness") the same way. Whether you qualify for the Streamlined Filing Compliance Procedures turns on which side of that line your facts fall, judged objectively and on the whole record.

Key takeaways

Non-willful means negligence, inadvertence, mistake, or a good-faith misunderstanding of the law. It is a statement about your state of mind, supported by facts.
Willful is not limited to intent. Courts in Bedrosian (3d Cir. 2018), Horowitz (4th Cir. 2020) and Rum (11th Cir. 2021) held that the civil willfulness standard includes reckless conduct.
The IRS carries the burden of proving willfulness for an FBAR penalty, but your own certification, signed under penalties of perjury, becomes part of the evidence.
Streamlined returns are not audited automatically, but they can be selected, and penalty protection falls away if an examination finds fraud or a willful FBAR violation.
If your honest assessment is that your conduct was willful, the Streamlined route is the wrong door. The IRS points those taxpayers to the Criminal Investigation Voluntary Disclosure Practice.

This article covers the legal standard and the evidence. For the mechanics of drafting the narrative itself, see our companion guide to writing the Form 14653 non-willful statement, and for eligibility, filing years and process, our IRS Streamlined Foreign Offshore Procedure guide.

The IRS definition of non-willful conduct

The IRS Streamlined Filing Compliance Procedures page defines non-willful conduct as conduct due to negligence, inadvertence, or mistake, or conduct resulting from a good-faith misunderstanding of the requirements of the law. Four ideas are packed into that sentence:

Negligence is a failure to exercise reasonable care. You should have done better, but you were not indifferent to the rules.
Inadvertence is an oversight: an account you forgot existed, an interest line that never reached your preparer.
Mistake covers errors of fact or calculation, such as misreading a statement or applying the wrong exchange rate.
Good-faith misunderstanding of the law covers the most common expat story: a sincere belief that paying tax abroad, or living abroad, meant no US filing was needed.

What the definition does not say matters just as much. It does not require that you had no idea FBARs existed, and it does not excuse you merely because you did not know. A taxpayer who knew nothing can still be found reckless if the warning signs were obvious; a taxpayer who knew something may still be non-willful if their misunderstanding was genuine and reasonable in context.

What "willful" means: three routes to the same finding

The civil FBAR penalty statute, 31 U.S.C. 5321(a)(5), distinguishes a non-willful violation (maximum penalty $10,000, adjusted for inflation) from a willful one (the greater of $100,000, adjusted for inflation, or 50% of the account balance at the time of the violation). The statute does not define "willful," so the meaning has come from the courts and from the IRS's own manual.

The Internal Revenue Manual at IRM 4.26.16 describes three ways willfulness can be shown in a civil FBAR case.

1. Knowing violation

The person knew of the reporting requirement and made a voluntary, conscious choice not to comply. This is the classic case, and it rarely fits the typical Streamlined applicant.

2. Reckless disregard

This is where most of the litigation has been. Recklessness is judged by an objective standard: did the conduct involve an unjustifiably high risk of violating the law that was known, or so obvious that it should have been known? The taxpayer's own subjective belief is not the end of the inquiry.

Bedrosian v. United States (3d Cir., opinion filed December 21, 2018): the Third Circuit held that FBAR willfulness is the civil standard, which includes both knowing and reckless conduct. Because it was unclear whether the district court had applied that objective standard, the court remanded the case rather than deciding it outright.
United States v. Horowitz (4th Cir., October 20, 2020): the court affirmed willful penalties against a highly educated couple who held close to $2 million in a Swiss account, signed returns whose Schedule B stated they had no foreign accounts, and never made a simple inquiry to their accountant. The court found their failure objectively reckless even accepting that they lacked actual knowledge of the FBAR rule. It also rejected the argument that an old regulation capped willful penalties at $100,000.
United States v. Rum (11th Cir., April 23, 2021): the court affirmed a willful penalty where the taxpayer held a numbered Swiss account with bank-held mail, never told his preparer about it, and filed returns answering "no" to the Schedule B foreign account question. It confirmed that willfulness includes reckless disregard of a known or obvious risk, and also rejected the $100,000 regulatory cap argument.

3. Willful blindness

The IRM also recognizes willfulness where a person made a conscious effort to avoid learning about the FBAR requirements. Deliberately not reading a question, not asking an adviser, or structuring affairs so that you never see a warning can be treated as knowledge.

The practical lesson: "I didn't know about the FBAR" is a starting point, not a defense. The question the IRS and the courts ask is whether, given what you knew about your accounts and what your returns asked you, a reasonable person in your position would have recognized the risk.

Facts that point each way

No single fact decides the question. The IRS and courts weigh the whole picture, and the Form 14653 instructions (revised March 2025) require you to tell "the whole story," favorable and unfavorable. The table below summarizes factors that commonly carry weight, drawn from the IRM discussion and the reasoning in the cases above.

| Factors that tend to support non-willful | Factors that tend to suggest willfulness |

|---|---|

| Accounts opened for ordinary reasons: local salary, mortgage, pension, joint account with a non-US spouse | Account opened or moved to conceal money from creditors, a spouse or the IRS |

| Accounts in your own name, with statements sent to your home address | Numbered accounts, nominee holders, bank-held mail, or sham entities |

| Foreign income was taxed locally and you reasonably believed that settled things | Returns answered "no" to the Schedule B foreign account question when accounts existed |

| Limited financial sophistication or little exposure to US tax rules | Professional background in finance, law or accounting, or heavy personal involvement in investment decisions |

| You told your preparer everything and relied on their advice | You withheld account information from your preparer, or never asked about accounts you knew were significant |

| You corrected course promptly once you learned of the rules | You continued non-compliance after receiving warnings (for example, bank letters about US reporting) |

| Consistent treatment: nothing reported selectively | Some accounts or years reported, others omitted without a coherent explanation |

| Funds came from documented, taxed sources | Unexplained deposits, cash movements, or transfers timed around disclosure deadlines |

Two points about this table. First, many applicants have facts in both columns, which is normal; the question is which account is more credible taken as a whole. Second, the Form 14653 instructions ask you to explain the source of funds in every foreign account. Unexplained money is one of the quickest ways for a narrative to lose credibility.

Worked example: why the label matters in dollars

The certification is not a formality, because the financial consequences on each side of the line are very different. Consider an illustrative US resident (hypothetical figures) whose foreign accounts had these aggregate year-end balances across the covered years, with a highest year of $240,000.

Route A: Streamlined Domestic Offshore Procedures (non-willful, US resident). The IRS applies a miscellaneous offshore penalty of 5% of the highest aggregate balance/value, determined by aggregating year-end balances for each year in the covered period and taking the highest year:

5% x $240,000 = $12,000, plus the tax and interest due on the amended returns.

Route A-foreign: Streamlined Foreign Offshore Procedures. If the same person met the non-residency test, the IRS page requires the full tax and interest due, and states that eligible taxpayers are not subject to failure-to-file, failure-to-pay, accuracy-related, information return or FBAR penalties. No offshore penalty payment is required.

Route B: a willful FBAR finding. The statutory maximum for a willful violation is the greater of $100,000 (as adjusted for inflation) or 50% of the account balance at the time of the violation, and willful penalties are measured by account balances, as the Supreme Court noted in contrasting them with non-willful penalties in Bittner v. United States (2023). The IRS applies internal mitigation guidelines, so the maximum is not automatic, but the exposure can be many multiples of the Streamlined figure.

For comparison, a non-willful FBAR finding outside Streamlined. In Bittner, the Supreme Court held that the $10,000 non-willful maximum accrues per report, not per account, which substantially limited exposure for taxpayers with many accounts.

The point of the example is not the arithmetic. It is that a certification which cannot survive scrutiny moves you from Route A into Route B, often after paying for Route A first.

How the IRS may review a certification

The IRS says Streamlined submissions will not be audited automatically, but they may be selected under the normal audit selection processes that apply to any return. In practice, a certification can be tested in several ways:

1. Processing review. An incomplete submission, or one without a narrative statement of facts, will not qualify for streamlined penalty relief, per the Form 14653 instructions.

2. Comparison with third-party data. Foreign banks report US account holders under FATCA, so the IRS may hold account information that it can set against your narrative.

3. Examination. If selected, an examiner can ask for statements, correspondence with advisers, account-opening documents and the history of your Schedule B answers.

4. Pattern checks. Selective reporting, late-opened accounts, and funds moved shortly before filing are the kinds of facts that invite closer questions.

The Form 14653 itself reminds signers that if the IRS receives or discovers evidence of willfulness, fraud or criminal conduct, it may open an examination or investigation that could lead to civil fraud penalties, FBAR penalties, information return penalties, or referral to Criminal Investigation.

What happens if a certification is later found to be false

The protections of the Streamlined procedures are conditional. The IRS pages for both the foreign and domestic procedures state that penalty relief does not apply if an examination determines that the original tax noncompliance was fraudulent and/or that the FBAR violation was willful. Additional tax found on examination may also attract penalties on those additional amounts, and previously assessed penalties are not abated.

Consequences can therefore include:

Loss of penalty protection for the years covered.
Willful FBAR penalties, measured against account balances.
Civil fraud penalties on the income tax side.
Criminal exposure. The certification is signed under penalties of perjury, and the IRS Streamlined page warns that returns may be subject to examination, additional civil penalties, and criminal liability, if appropriate.

There is also a one-way-door problem. The IRS states that once a taxpayer makes a Streamlined submission, the taxpayer may not participate in the (now-closed) Offshore Voluntary Disclosure Program. Choosing the wrong route first can narrow the options that remain.

When Streamlined is the wrong door

The IRS is explicit: taxpayers concerned that their failure to report income, pay tax and file information returns was due to willful conduct should consider the IRS Criminal Investigation Voluntary Disclosure Practice. That program is designed for taxpayers with potential criminal exposure. Key features, per the IRS page:

It begins with a preclearance request on Form 14457.
It generally covers the most recent six years of returns and reports.
A disclosure must be timely, which means, among other things, made before the IRS has received information from a third party (such as an informant, another agency or a John Doe summons) alerting it to your noncompliance.
It does not automatically guarantee immunity from prosecution, though a voluntary disclosure may result in prosecution not being recommended.

The Streamlined procedures are also unavailable if the IRS has already initiated a civil examination of your returns for any year, if you are under criminal investigation by IRS Criminal Investigation, or if you lack a valid taxpayer identification number. For a side-by-side comparison of the two routes, see Streamlined procedure vs voluntary disclosure.

A step-by-step way to assess your own conduct

Before anyone drafts a certification, work through the facts in this order:

1. List every foreign account and asset for the full six-year FBAR period, including dormant, joint, pension and signature-authority accounts.

2. Trace the source of funds in each account: salary, sale proceeds, inheritance, gifts. Gather documents that show it.

3. Pull every US return you filed and check the Schedule B foreign account answers year by year.

4. Reconstruct what you knew and when: bank letters about US status, conversations with preparers, emails, forum posts you read.

5. Identify your advisers and what they were told. Reliance on a professional only helps if you gave them the full picture.

6. Place each fact in the table above, honestly, in whichever column it belongs.

7. Decide the route: Streamlined Foreign, Streamlined Domestic, delinquent FBAR submission (if no tax is owed), or a Voluntary Disclosure Practice consultation, before any filing is made.

8. Only then draft the narrative, using the method in our Form 14653 guide.

Common mistakes

Treating "I didn't know" as the whole story. After Horowitz and Rum, lack of actual knowledge does not answer the recklessness question.
Ignoring the Schedule B problem. A "no" answer on a signed return, when accounts existed, is a fact you must address, not hope goes unnoticed.
Leaving out unfavorable facts. The form requires them. Omissions discovered later damage credibility far more than facts explained up front.
Blaming a preparer you never told. Reliance arguments fail where the preparer was not given the information.
Moving or closing accounts just before filing. Timing like this can look like concealment.
Choosing Streamlined because it is cheaper. The route follows the facts, not the price. A certification that cannot withstand examination is the most expensive outcome of all.
Mixing willful and non-willful accounts in one certification. A single deliberate omission can color the entire submission.

When to get professional help

Whether conduct was non-willful is a legal judgment about your specific facts, and the certification you sign carries real consequences if it is wrong. If your facts sit clearly in the left-hand column, the process is usually straightforward; if any fall in the right-hand column, get advice before you file anything. At Next Tax Source, an IRS Enrolled Agent reviews and signs off on every Streamlined package, and cases that point toward willfulness are escalated for specialist legal input rather than forced into the wrong program. You can book a consultation to review your facts before choosing a route. This article is general information, not advice on your individual situation.

Frequently asked questions

What is the IRS definition of non-willful conduct?+

For the Streamlined Filing Compliance Procedures, the IRS defines non-willful conduct as conduct due to negligence, inadvertence or mistake, or conduct resulting from a good-faith misunderstanding of the requirements of the law. It describes your state of mind when you failed to report income, pay tax or file information returns such as FBARs. You certify it on Form 14653 (outside the US) or Form 14654 (US residents), under penalties of perjury, supported by a narrative of the specific facts.

What is the difference between willful and non-willful FBAR violations?+

A non-willful FBAR violation arises from negligence, oversight or a good-faith misunderstanding. A willful violation covers knowing violations and, according to federal appeals courts in Bedrosian, Horowitz and Rum, reckless disregard of an obvious risk. The IRS manual also treats willful blindness as willful. The penalties differ sharply: the statutory maximum is $10,000 (inflation adjusted) per non-willful violation, but the greater of $100,000 (inflation adjusted) or 50% of the account balance for a willful one.

What is willful blindness in an FBAR case?+

Willful blindness is a conscious effort to avoid learning about the FBAR reporting requirements. The Internal Revenue Manual (IRM 4.26.16) treats it as a form of willfulness for civil FBAR penalties, alongside knowing and reckless violations. Examples include deliberately not reading the foreign account question on Schedule B, avoiding asking an adviser, or arranging affairs so that you never receive warnings from your bank. Someone who chose not to know can be treated as if they knew.

Is not knowing about the FBAR enough to qualify as non-willful?+

Not on its own. Courts have held that civil willfulness includes objective recklessness, so lack of actual knowledge does not settle the question. In Horowitz, the Fourth Circuit upheld willful penalties even accepting the couple did not know of the FBAR rule, because they held large sums abroad, signed returns saying they had no foreign accounts, and never asked their accountant. What matters is whether the risk was so obvious that a reasonable person in your position should have recognized it.

Can the IRS challenge a Streamlined non-willful certification?+

Yes. The IRS says Streamlined returns are not audited automatically but may be selected under its normal audit selection processes. If an examination determines that the original noncompliance was fraudulent or that an FBAR violation was willful, the Streamlined penalty protection does not apply. Form 14653 itself warns that evidence of willfulness, fraud or criminal conduct may lead to civil fraud penalties, FBAR penalties, information return penalties or referral to IRS Criminal Investigation.

What happens if my non-willful certification turns out to be false?+

You can lose the Streamlined penalty relief for the covered years and face willful FBAR penalties, civil fraud penalties on the tax side, and penalties on any additional tax found. Because the certification is signed under penalties of perjury, a knowingly false statement can also create criminal exposure; the IRS warns of criminal liability where appropriate. This is why the route should be chosen on an honest reading of the facts, not on which program costs less.

When should I use the IRS Voluntary Disclosure Practice instead of Streamlined?+

The IRS says taxpayers concerned that their failure to report income, pay tax and file information returns was due to willful conduct should consider the IRS Criminal Investigation Voluntary Disclosure Practice. It starts with a Form 14457 preclearance request, generally covers the most recent six years, and must be made before the IRS has received information about your noncompliance, for example from a third party. It does not guarantee immunity, but may result in prosecution not being recommended.

How much does Streamlined cost compared with a willful penalty?+

Under the Streamlined Domestic Offshore Procedures, the miscellaneous offshore penalty is 5% of the highest aggregate year-end balance of the relevant foreign assets across the covered years, plus tax and interest. Under the Streamlined Foreign Offshore Procedures, eligible taxpayers pay tax and interest with no FBAR or offshore penalty. A willful FBAR penalty, by contrast, can reach the greater of $100,000 (inflation adjusted) or 50% of the account balance at the time of the violation.
