FBAR Penalties: What Happens If You Don't File?

FBAR penalties are among the harshest in US tax enforcement. If you have foreign financial accounts worth over $10,000 total during the calendar year, you must file an FBAR under 31 CFR 1010.350. Failure to file an FBAR can trigger significant penalties under 31 USC 5321. It can also lead to criminal prosecution and prison time.

The severity of FBAR penalties depends on whether your failure to file was willful or non willful. Non willful penalties cap at $12,909 per violation under 31 USC 5321(a)(5)(B). However, willful violations can reach $100,000 or 50% of your account balance under 31 USC 5321(a)(5)(C). The IRS has six years to assess penalties for each missed filing. FATCA sends data from over 300,000 foreign banks to the IRS. The chance of discovery grows every year you wait to file.

What Are FBAR Penalties Under the Bank Secrecy Act?

FBAR penalties are civil and criminal fines for failure to file a foreign bank account report of foreign bank and financial accounts. The Bank Secrecy Act requires US persons to report foreign bank accounts and other financial accounts to the Financial Crimes Enforcement Network (FinCEN) each calendar year. Additionally, FBAR penalties fall into three tiers: non willful, willful, or criminal. The amount of FBAR penalties depends on your intent and the value of your unreported foreign accounts.

How Severe Are Non Willful FBAR Penalties?

Non willful penalties apply when you failed to file an FBAR due to honest mistakes or not knowing about the filing requirement. The IRS maximum penalty for each non willful violation is $12,909 under 31 USC 5321(a)(5)(B)(i). This is the 2026 amount per the Federal Civil Penalties Inflation Adjustment Act. The base $10,000 penalty under 31 USC 5321 is adjusted annually. Therefore, these penalties grow across multiple years.

How Does the IRS Count Non Willful Violations?

The Supreme Court ruled in United States v. Bittner (2023) that non willful penalties apply per annual report — not per account. If you failed to file an FBAR covering five foreign bank accounts for one calendar year, the IRS counts one violation under 31 USC 5321(a)(5)(B). Miss filing FBARs for three years? That equals three violations: up to $38,727 in FBAR penalties under 31 USC 5321.

Can You Show Reasonable Cause to Avoid Penalties?

Yes. The IRS may reduce or eliminate penalties if you show reasonable cause for your failure to file. Reasonable cause means you tried to comply but missed the filing requirement. Factors include reliance on a tax preparer who did not ask about foreign accounts, no FBAR filing history, and honest mistakes about the $10,000 threshold under 31 CFR 1010.350. However, reasonable cause does not apply to willful violations.

What Are Willful FBAR Penalties?

Willful penalties are far more severe. The civil penalty for willful failure to file an FBAR is the greater of $100,000 or 50% of the account balance per violation under 31 USC 5321(a)(5)(C). These amounts are also adjusted annually for inflation. A single willful failure to file can produce harsh penalties. The total can exceed the value of your foreign financial accounts.

How Does the IRS Count Willful Violations?

Unlike non willful violations, the IRS assesses willful penalties per account, per year. For example, five unreported foreign bank accounts for three years equals 15 violations under 31 USC 5321(a)(5)(C). For a $400,000 Swiss bank account, the IRS can impose a $200,000 penalty per year under 31 USC 5321(a)(5)(C). Over three years, penalties on that single account reach $600,000. In FBAR cases involving swiss accounts, courts have upheld penalties over 100% of the account value.

Why Does Schedule B Matter for Willfulness?

Schedule B of your tax returns includes a box indicating whether you have a financial interest or signature authority over foreign financial accounts. Checking "No" on Schedule B while holding foreign bank accounts is strong evidence of willfulness. In district court FBAR cases, judges ruled that checking the wrong box — combined with failing to file FBARs — supports willful failure to file under 31 USC 5321(a)(5)(C). Your tax preparer should ask about foreign accounts when completing Schedule B on your tax returns.

What Are Criminal Penalties for FBAR Violations?

Criminal penalties are the most severe tier. Under 31 USC 5322, willful failure to file an FBAR carries up to $250,000 in fines and 5 years in prison. When violations connect to tax evasion under 26 USC 7201, criminal penalties increase to $500,000 in fines and 10 years. Consequently, criminal penalties apply on top of civil penalties.

When Does the IRS Pursue Criminal Prosecution?

IRS Criminal Investigation targets FBAR cases with large unreported accounts (often $1,000,000+), active concealment, and tax evasion across multiple years under 31 USC 5322. In tax evasion cases, charges were filed most often when the taxpayer had swiss accounts or destroyed records. Criminal prosecution brings a grave risk of more penalties under 31 USC 5321, back taxes, and interest on unreported foreign income.

Willful vs. Non Willful: How Does the IRS Decide?

The willful vs. unintentional question determines whether you face penalties of $12,909 per year under 31 USC 5321(a)(5)(B) or willful penalties exceeding $100,000 under 31 USC 5321(a)(5)(C). Courts apply the Safeco Insurance Co. v. Burr standard: willfulness means a "knowing violation of a known legal duty." In other words, proof of intent to break the law is not required — only that you knew about the requirement and chose not to file an FBAR.

Factors That Indicate Willful Failure

• Checking "No" on Schedule B while holding foreign bank accounts
• Ignoring advice from a CPA or tax preparer about FBAR reporting
• Large balances in foreign financial accounts
• Active concealment: nominee names, structuring, or secrecy havens
• Filing FBARs for some accounts but not others

Factors That Indicate Non Willful Conduct

• No prior filing history, especially for immigrants or green card holders
• No unreported foreign income — no tax benefit from concealment
• Reliance on a tax preparer who did not ask about foreign accounts
• Prompt voluntary disclosure before IRS contact
• Honest mistakes about the $10,000 aggregate value threshold

Penalty Comparison: Willful vs. Non Willful

Factor	Non Willful	Willful
Maximum civil penalty	$12,909 per year (31 USC 5321(a)(5)(B))	$100,000 or 50% of balance per account per year (31 USC 5321(a)(5)(C))
Violation counted per	Annual FBAR report	Each account, each year
Criminal penalties risk	None	Possible
IRS must prove	Mistake or ignorance	Knowledge or reckless disregard

What Is the FBAR Statute of Limitations?

The FBAR statute of limitations is six years. The IRS can assess penalties for up to six years from the due date under 31 USC 5321(b)(1). The due date for each calendar year is April 15 of the following year per 31 CFR 1010.306(c). As a result, potential penalties grow every year you do not file delinquent FBARs for your accounts. FATCA sends data from over 300,000 institutions to the IRS. See FBAR statute of limitations.

How Can You Fix Past Non-Filing and Avoid Penalties?

If you have unreported foreign financial accounts, three paths can help you file late FBARs for those accounts and avoid penalties. Acting before you are contacted is the most effective way to eliminate penalties. Here are the steps:

1. Determine whether your failure to file was willful or not
2. Choose the right program to file based on your situation
3. File all delinquent FBARs through BSA E-Filing
4. Report any unreported foreign income on amended tax returns
5. Pay any taxes, interest, and applicable penalties

For detailed information, see our guides on delinquent filing procedures and streamlined filing.

Path 1: Delinquent FBAR Submission Procedures

If you reported all foreign income on your tax returns but missed the FBAR filing, you can file late FBARs with zero penalties. File your delinquent FBARs online and include a statement explaining why each FBAR is late. In most cases, penalties are rarely assessed when you reported all foreign income. This is the best path for filing late. See our first-time filer guide.

Path 2: Streamlined Filing Compliance Procedures

The IRS Streamlined Procedures help non willful filers who also have unreported foreign income. You file three years of amended tax returns and six years of delinquent FBARs. You also pay back taxes plus a 5% offshore penalty on the highest aggregate value of your foreign financial accounts per IRC guidelines. For a peak value of $250,000, the penalty is $12,500 per IRC — far less than enforcement. Filers outside the US for 330+ days owe zero penalty.

Path 3: Voluntary Disclosure Practice

Filers whose non-compliance was willful should consider the Voluntary Disclosure Practice. You avoid criminal prosecution but pay civil penalties — often 75% of total tax liability. A tax attorney is necessary for those who file under this program.

Real-World FBAR Penalty Cases

United States v. Zwerner (2014)

Carl Zwerner held swiss accounts at UBS worth about $1.69 million. He argued his failure to file was unintentional. A jury in district court disagreed. The court concluded that his conduct was willful under 31 USC 5321(a)(5)(C) and assessed a penalty of $2.24 million. The court stated that stacked annual willful penalties can exceed the total foreign bank account value.

United States v. Bittner (2023, Supreme Court)

Alexandru Bittner missed filing FBARs for five years covering 272 foreign accounts. The government filed suit claiming $2.72 million in penalties under 31 USC 5321 — per account. The Supreme Court ruled 5-4 that penalties for unintentional violations apply per annual report, not per account. This ruling does not apply to willful violations. See our FBAR vs. FATCA comparison.

What Are Current IRS Enforcement Trends?

IRS enforcement of FBAR penalties has grown since FATCA took effect. The agency receives data from over 300,000 financial accounts worldwide. It cross-references FBAR filings against FATCA data, foreign accounts records, and Schedule B disclosures on tax returns. Additionally, John Doe summonses have forced foreign banks to release account holder records. The IRS also pursues FBAR issues connected to cryptocurrency on foreign exchanges — see our guide on FBAR and cryptocurrency. If you hold foreign financial accounts, you must file FBARs or face FBAR penalties.

Frequently Asked Questions About FBAR Penalties

These answers cover common questions about FBAR penalty amounts, the filing deadline, and options for filers who missed filing in prior years. If willfulness may be an issue, consult a tax attorney before filing.

Is the IRS waiving penalties for late FBAR if all income is properly reported?

In practice, yes. The Delinquent FBAR Submission Procedures allow late filers to submit overdue FBARs for their accounts without penalties — provided they reported all foreign income on their tax returns. File late FBARs through BSA E-Filing with an explanation. The IRS exercises discretion under 31 USC 5321(a)(5)(B)(ii) to waive penalties when reasonable cause exists.

Can the IRS assess FBAR penalties and income tax penalties together?

Yes. FBAR penalties are separate from income tax penalties under the Bank Secrecy Act. If you had unreported foreign income, the IRS can assess income tax and accuracy-related penalties of 20-40% under IRC 6662. It can also charge interest on unpaid tax liability and FBAR penalties under 31 USC 5321. Meeting your tax obligations on your tax returns does not satisfy FBAR reporting rules.

How does the FBAR due date and automatic extension work?

The FBAR for each calendar year is due April 15 of the following year, with an automatic extension to October 15 under 31 CFR 1010.306(c). No request is needed. See our FBAR filing deadline guide.

Do I need to report the maximum value of each foreign bank account on the FBAR form?

Yes. You must report the maximum value of each foreign financial account during the calendar year on your FBAR form. This includes all foreign bank and financial accounts with signature authority, and accounts where you have a financial interest. Use Treasury Department exchange rates from your bank statements. See how to calculate maximum account value.

Is there a penalty waiver for first-time filers?

The IRS has discretion to waive non willful penalties for first-time filers who reported all income under 31 USC 5321(a)(5)(B)(ii). The Delinquent FBAR Submission Procedures provide a path to file FBARs with no penalty. There is no formal statutory waiver for these accounts.
