Why correcting FBAR errors matters

FBARs (FinCEN Form 114) disclose U.S. persons’ foreign financial accounts when the aggregate value exceeds $10,000 at any point in a calendar year. Mistakes — missing accounts, wrong account numbers, incorrect maximum balances, or failure to convert foreign-currency values to U.S. dollars properly — can trigger civil penalties and, in severe cases, criminal exposure. Filing corrected information quickly, documenting your reasoning, and choosing the right remedy are the best defenses against enforcement action (FinCEN Instructions for Form 114; IRS: Reporting Foreign Bank Accounts).

In my practice, clients who correct honest mistakes early — and who follow one of the recognized correction pathways below — almost always avoid the largest penalties and limit escalation to audits or criminal referrals. The rest of this guide walks through practical, step-by-step options and documents you should collect.

Overview: How FBAR corrections are generally handled

There are three common pathways to correct FBAR errors depending on facts and intent:

  • File an amended FBAR for straightforward mistakes where the original filing was timely and the error is limited.
  • Use the Delinquent FBAR Submission Procedures when a filing was required but missed and there is no IRS civil examination or criminal investigation.
  • Use the Streamlined Filing Compliance Procedures if the failure to file was non-willful and you want to resolve prior-year noncompliance with reduced penalties.

Which path you choose depends on whether the error was willful, whether the taxpayer is under investigation, and the number and size of unreported accounts.

Step-by-step: Correcting an FBAR error (practical checklist)

  1. Identify exactly what is wrong
  • Which calendar year(s) are affected? FBAR is filed by calendar year. Identify omissions (accounts or years), incorrect maximum balances, wrong account numbers, or mistakes in account types (e.g., brokerage vs. bank).
  • Determine whether the error appears to be willful. Willfulness changes the recommended approach.
  1. Collect supporting documentation
  • Bank statements that show the account balances across the year and the maximum value.
  • Account-opening documents, statements showing account numbers and ownership, wire or transfer records, and any correspondence with the foreign institution.
  • Currency exchange evidence if balances were converted to USD (see FinCEN instructions on reporting values) (FinCEN Instructions).
  1. Decide which filing route to use
  • Amended FBAR: If you originally filed an FBAR and simply need to change one or two items (account number, maximum value, etc.), file an amended FBAR electronically through the BSA E-Filing System and mark it as “Amended.” This corrects the record; include an explanation in your records. See the FinCEN instructions for the procedure.
  • Delinquent FBAR Submission Procedures: If you failed to file and are not under civil or criminal inquiry, you may file delinquent FBARs electronically and attach a statement explaining why the filings were late. This path is not a formal penalty waiver but is accepted for straightforward oversights (IRS: Reporting Foreign Bank Accounts).
  • Streamlined Filing Compliance Procedures: For non-willful failures, the Streamlined Procedures can regularize prior-year reporting (FBAR and income tax returns) and usually avoid FBAR penalties if eligibility tests are met. These require specific certifications of non-willfulness and submission of amended returns and FBARs for specified years.
  1. Prepare and submit the corrected filings
  • Use BSA E-Filing to submit amended FBARs (FinCEN Form 114). There is no paper alternative. Keep timestamps and confirmation numbers.
  • When using Streamlined or Delinquent procedures, follow IRS directions for attaching statements and where to send supporting documents.
  1. Retain a complete working paper file
  • Keep copies of original FBARs, amended FBARs, bank statements, currency conversion calculations, and a signed memo describing why and how the error occurred. Preserve communications with tax advisors.
  1. If you’re unsure or the case is complex, get professional help
  • Willful failures, very large unreported balances, or situations involving offshore structures require counsel experienced with international tax enforcement. Early representation can materially change outcomes.

Examples and common scenarios

  • Omitted small personal savings account: Often corrected by filing an amended FBAR for the specific year(s), documenting an honest oversight, and using Delinquent Filing Procedures if the original FBAR was never filed.

  • Wrong maximum balance reported: Amend the FBAR for the year and attach/keep statements showing the correct maximum balance and conversion to USD.

  • Multiple years of omission but non-willful: Streamlined Filing Compliance Procedures are often the most efficient way to resolve both FBARs and unreported income with reduced risk of large FBAR penalties.

  • Willful concealment or large undeclared offshore structures: Engage a tax attorney immediately; voluntary disclosure options and negotiated settlements may be complex and high-stakes.

How penalties work and why the remedy matters

FBAR penalties differ dramatically by intent:

  • Non-willful violations: civil penalties historically have been assessed up to $10,000 per violation in many cases. The IRS and DOJ evaluate facts and may mitigate penalties, especially with prompt corrective action and cooperation (see our deeper dive on willful vs non-willful penalties: Willful vs. Non-Willful FBAR Penalties).
  • Willful violations: penalties are far larger — commonly the greater of $100,000 or 50% of the account’s balance at the time of the violation — and criminal prosecution becomes a real risk. Because of that, allegations of willfulness require immediate professional representation.

Understanding intent — and documenting a good-faith effort to comply — is a central part of reducing or avoiding penalties.

Practical tips I use with clients

  • Start with a complete inventory of foreign accounts and the maximum balance for each calendar year. This simple spreadsheet prevents many errors.
  • Use confirmed bank statements to convert foreign currency balances into USD and record the conversion method used. FinCEN instructions permit reasonable conversion methods; consistency and documentation matter (FinCEN Instructions).
  • If you’re eligible for Streamlined Procedures, follow the IRS checklist exactly and include all required tax returns and certifications. Minor deviations can delay acceptance.
  • When filing an amended FBAR, always keep the BSA E-Filing confirmation and a short explanatory memo in your file describing why you amended the form.

Frequently asked questions (short answers)

  • Can I just mail an amended FBAR? No — FinCEN requires FBAR submissions (including amended forms) to be filed electronically via the BSA E-Filing System.

  • How far back should I correct FBARs? The appropriate lookback depends on the remedy. Streamlined Procedures typically require filing amended returns and FBARs for specific prior years (see IRS Streamlined guidance). For other routes, consult the applicable procedure instructions or a qualified advisor.

  • Will correcting an FBAR trigger an audit? Filing corrected information can prompt further review, but failing to correct known errors substantially increases enforcement risk. Voluntary, well-documented corrections typically reduce the chance of severe penalties.

Final notes and professional disclaimer

Correcting FBAR errors promptly and with complete documentation is the most reliable way to reduce enforcement exposure. In my practice, taxpayers who take early, transparent steps to amend FBARs and follow the IRS/FinCEN procedures typically see better outcomes than those who wait for a government inquiry.

If you face possible willful noncompliance, or your situation involves significant unreported balances or complex offshore arrangements, consult a qualified international tax attorney or CPA immediately.
