FBAR Compliance

FBAR, the Report of Foreign Bank and Financial Accounts, is required under 31 U.S.C. section 5314 for any U.S. person with qualifying foreign accounts that exceeded $10,000 in total value during the year. This page covers how FBAR reporting works, the penalties for non-willful and willful violations, and what happens when the IRS opens an FBAR audit.

Many people learn about FBAR only after a life change, a new accountant, or a bank inquiry raises the question. What looks like a simple reporting issue can raise concerns about past filings and balances. An FBAR attorney can review what applies to your situation, identify gaps, and prepare any late filings needed, reducing the risk of inconsistent submissions that draw unnecessary scrutiny.

How FBAR reporting works

The FBAR requirement comes from the Bank Secrecy Act, including 31 U.S.C. section 5314 and its regulations. It requires FinCEN Form 114, filed separately from your income tax return, which is where misunderstandings often start. The form is submitted electronically through FinCEN's BSA E-Filing System, and it covers a wide range of foreign accounts, including bank accounts, brokerage accounts, mutual funds, and some pension and insurance policies held abroad.

The filing deadline lines up with the federal tax return due date in April, with an automatic extension to October. Ownership structures, joint accounts, signature authority, and foreign retirement plans all affect how the reporting framework applies, and documentation matters because penalties under 31 U.S.C. section 5321 often turn on how the IRS reads your intent and recordkeeping.

• Listing all relevant foreign accounts and confirming yearly peak balances
• Clarifying who had access or authority over each account
• Comparing FBAR duties with prior tax filings
• Organizing records that support the reporting timeline
• Preparing explanations that align with the financial documents

FBAR penalties

Penalties for failing to file fall into two categories, non-willful and willful, and a late filing is treated under whichever classification applies to the taxpayer's conduct.

Non-willful penalties

The most common FBAR penalty is non-willful, and it typically applies when a taxpayer did not know about the filing requirement or misunderstood the reporting threshold, often because they had not lived abroad long or had not received the right professional advice. These penalties can run up to $16,536 per FBAR form, assessed for the year in question rather than per account, and the IRS has discretion to reduce or waive them.

Willful penalties

Willful penalties are less common but far more serious. The IRS treats a violation as willful when a taxpayer knew the reporting rules and still failed to file, filed a Schedule B falsely denying foreign accounts, or ignored IRS notices. The penalty is the greater of $165,353 or fifty percent of the account balance, assessed per account per year in which reporting did not occur.

A late FBAR is still a violation, and the same non-willful or willful penalty structure applies depending on how the delay is classified. Filing as soon as possible, and working with an attorney to negotiate with the IRS, keeps potential penalties to a minimum and shows the agency you intend to come into compliance.

When the IRS gets involved

If an IRS inquiry begins, the situation often shifts from correction to defense. Some taxpayers address a reporting gap voluntarily before contact, while others first learn of it through an examination. An attorney can evaluate whether streamlined procedures, delinquent filings, or another compliance path fits, and consistency between your FBAR submissions and other tax disclosures matters throughout.

What triggers an FBAR audit

An FBAR audit can happen even when you are fully compliant, and the IRS most often opens one for a few recurring reasons:

• A history of past noncompliance, prior audits, or prior penalties involving foreign accounts
• Failure to file a required FinCEN Form 114, even an accidental omission
• Random selection through statistical sampling
• Discrepancies between reported income and available financial data suggesting an unreported account

What an FBAR audit looks like

You will receive notice before an audit begins, generally by mail to your last known address, since the IRS does not typically initiate contact by phone or email. Some taxpayers receive Letter 4265, an FBAR appointment letter that schedules the examination and specifies which tax years are under review. Read it carefully before deciding on next steps.

Audits usually take several months, whether or not an in-person examination is requested. They can run longer when the IRS asks for more documents. You have the right to an attorney throughout the process, and early responses can influence how the IRS views your cooperation and intent.

FBAR obligations often overlap with FATCA reporting; see our international tax overview for how these cross-border duties fit together.
