What Are the FBAR Penalties If I Didn’t File?

If you missed filing your FBAR, here’s what matters: The IRS will not impose penalties if you reported all income, paid all taxes, and filed delinquent FBARs before they contact you. Most expats using voluntary disclosure programs pay nothing.

FBAR penalties target intentional tax evaders, not Americans who are unaware of the form. Whether you face penalties depends on one question: Did you know you were supposed to file?

If you genuinely didn’t know, penalties are typically waived or minimal—especially when you come forward first. Even if penalties apply, recent court rulings have cut how they’re calculated. Here’s what you face and how to fix it.

How Much Will I Pay in FBAR Penalties?

Penalties depend on whether the IRS determines your failure was willful or non-willful.

Non-Willful Penalties

Amount: Up to $16,536 per form (adjusted annually for inflation)
Calculation: Per FBAR form, NOT per account (2023 Supreme Court Bittner decision)
Example: Failed to file one FBAR reporting 5 accounts worth $50,000 = ONE penalty up to $16,536, not five.
Reality: IRS frequently reduces or waives non-willful penalties for reasonable cause.

Willful Penalties

Amount: Greater of $165,353 OR 50% of account balance (adjusted annually for inflation)
Calculation: Per account, per year

Example:

Account balance: $200,000
Years not filed: 3
Penalty per year: $100,000 (50% of $200,000)
Total: $300,000

Criminal Penalties (Rare)

Fraud or tax evasion cases only:

Fines up to $250,000
Imprisonment up to 5 years
Civil AND criminal penalties can combine

Didn’t File an FBAR and Feeling Anxious?

Not every missed FBAR results in penalties. The outcome depends on how and when you fix it.

What Makes a Violation “Willful” vs “Non-Willful”?

The difference determines whether you face manageable penalties or devastating financial consequences.

Non-Willful (Most Common)

You didn’t file because: You didn’t know about FBAR, misunderstood the $10,000 threshold, your tax preparer never mentioned it, recently moved abroad, or relied on incorrect professional advice.

IRS view: Honest mistake made in good faith

Willful (Rare but Serious)

The IRS considers it willful when: You knew about FBAR and chose not to file, checked “no” on Schedule B knowing you had foreign accounts, ignored IRS notices, actively hid accounts, or were “willfully blind” to your obligations.

IRS view: Intentional non-compliance

The Schedule B Question

Checking “no” on Schedule B about foreign accounts doesn’t automatically make you willful. The IRS examines your entire situation: Did you report all income? Did you cooperate when contacted? One checkbox doesn’t determine willfulness.

How Do I Avoid Penalties?

Three pathways. Most result in $0 penalties if you act before the IRS contacts.

1. Delinquent FBAR Procedures

For: Filed all taxes correctly but forgot FBARs
Requirements: Reported all income, paid all taxes, not under examination
Action: File up to 6 years of FBARs electronically with a brief reasonable cause explanation
Penalty: $0

Details

2. Streamlined Filing

For: Missed both tax returns AND FBARs (non-willful)
Action: File 3 years taxes + 6 years FBARs + Form 14653 + pay back taxes with interest
FBAR Penalty: $0 for expats abroad

Details

3. File Immediately

For: Current year late only
Automatic extension to October 15. Mark “delinquent” and explain briefly.

What Counts as “Reasonable Cause” to Waive Penalties?

Even if penalties apply, you can request a waiver by demonstrating reasonable cause:

Strong arguments: Recently moved abroad and didn’t know the requirements, relied on a professional preparer who didn’t mention FBAR, complicated family situation, health/family emergencies, correctly reported all income and paid all taxes.

Weak arguments: Didn’t read instructions, form too complicated, thought only rich people file.

Key: Documentation. Gather evidence supporting your claim (preparer correspondence, medical records, proof of income reporting).

How Does the IRS Find Out About Unreported Accounts?

FATCA Reporting: Foreign Account Tax Compliance Act requires foreign banks to report U.S. account holders directly to the IRS.
Schedule B Cross-Referencing: IRS matches foreign account questions on tax returns with FBAR filings.
International Agreements: Automatic exchange of financial data with many countries.
Audits: Examiners review foreign income and ask about foreign accounts.

Bottom line: With global reporting requirements, unreported accounts are increasingly easy to detect.

Real Penalty Examples

Sarah: Digital Nomad (Non-Willful)

Facts: Worked remotely in Thailand for 3 years. Thai accounts totaling $25,000. Filed U.S. taxes, excluded income via FEIE, didn’t know about FBAR.
Action: Filed 3 years delinquent FBARs with a reasonable cause explanation when the tax preparer mentioned it.
Result: $0 penalties

Michael: Intentional Non-Filer (Willful)

Facts: Swiss accounts totaling $500,000 for 5 years. Checked “no” on Schedule B, knowing he had foreign accounts, and ignored IRS notices.
Action: None until IRS examination.
Result: $750,000 penalties (50% × 3 years)

Lesson: Sarah came forward. Michael hid. Sarah paid nothing. Michael paid 150% the account value.

Can I Appeal or Reduce My FBAR Penalties?

Yes. You have appeal rights:

Pre-Assessment: After receiving the proposed penalty letter (Letter 3709), you have 30 days to respond with objections and reasonable cause arguments.
Post-Assessment: After penalties are assessed, you can appeal and negotiate with IRS Appeals.
Mitigation Factors: Compliance history, account balances relative to penalties, cooperation level, and economic hardship.
Eighth Amendment: Recent court cases have successfully challenged excessive penalties as unconstitutional.
Statute of Limitations: The IRS can assess penalties for up to 6 years from the due date. File at least 6 years of delinquent FBARs to be comprehensive.
