IRS Foreign Reporting Penalties: FBAR, 8938, 5471, 5472 and 3520

The IRS foreign reporting penalties are some of the steepest in the tax code, because they attach to missing paperwork rather than to unpaid tax. A person who owes nothing can still face a penalty for failing to file an FBAR, Form 8938, Form 5471, Form 5472 or Form 3520. For anyone with Indian savings accounts, a Canadian RRSP or TFSA, shares of a foreign company or a gift from a relative abroad, knowing the amounts, the defences and the correction routes is essential.

What are the IRS foreign reporting penalties for each form?

The FBAR figures come from the table in 31 CFR 1010.821, which lists maximums for penalties assessed on or after January 17, 2025, and the table is adjusted annually, so check for a newer one before relying on these numbers. The Form 8938, 5471, 5472 and 3520 amounts come from the IRS form instructions in effect in October 2026; those statutory amounts are not indexed in the same table.

How the FBAR penalty works after Bittner

The IRS manual says a failure to file a legally compliant FBAR is a single violation, so a non-willful violation produces a single penalty regardless of how many accounts were left off. In 2023 the Supreme Court decided Bittner v. United States on that point, and the IRS revised its manual in response. Willful violations, by contrast, can generate a penalty for each account. In most non-willful cases examiners recommend one penalty per violation, exercise discretion, and may issue a warning letter instead. The manual caps total non-willful penalties across open years at 50 percent of the highest aggregate balance of the accounts involved.

Who can ask for reasonable cause relief?

The Form 8938 and Form 3520 instructions say no penalty applies if the failure was due to reasonable cause and not willful neglect, and the Form 8938 instructions add that you must affirmatively show the facts. For other information returns, the IRS's delinquent filing procedures let you attach a reasonable cause statement to each late form. Two points matter for cross-border filers. First, the fact that a foreign country would impose a penalty for disclosing the information is not reasonable cause. Second, the IRS says reliance on a tax professional is generally not a valid reason by itself for failing to file or pay on time, so keep records of what you gave your preparer and when. Our penalty abatement playbook explains how to document it. Note that the IRS's first-time abatement relief covers late-filing, late-payment and late-deposit penalties; it does not extend to FBAR or foreign information return penalties.

How to fix missed foreign filings, step by step

1. Stop and collect facts. List every foreign account, entity, trust, gift and the years involved. Gather statements, formation documents and account opening dates.
2. Check whether the IRS has contacted you. If you are under a civil examination or criminal investigation, the streamlined procedures are not available and you need representation first.
3. Decide the willfulness question honestly. Non-willful conduct is negligence, inadvertence, mistake or a good faith misunderstanding of the law. If there is any chance your conduct could be seen as willful, speak to a tax attorney before filing; the IRS points those taxpayers to its Criminal Investigation Voluntary Disclosure Practice and tells them to consult professional or legal advisers.

Step four is choosing the route that fits your facts:

• Delinquent FBAR. The IRS says to file late FBARs as soon as possible if it has not contacted you and you are not under investigation, and to explain why you are late.
• Delinquent information returns. File them through normal procedures and attach a reasonable cause statement. Statements on Forms 3520 and 3520-A are considered before a penalty is assessed; for other forms a penalty may be assessed before the statement is reviewed, so be ready to answer IRS correspondence.
• Streamlined domestic offshore procedures. For non-willful U.S. residents: file amended returns for the most recent three years, delinquent FBARs for the most recent six years, and pay a miscellaneous offshore penalty of 5 percent of the highest aggregate balance of the foreign assets involved. Applicants certify non-willful conduct on Form 14654.
• Streamlined foreign offshore procedures. For qualifying non-residents, the IRS states that those who comply are not subject to failure-to-file, failure-to-pay, accuracy-related, information return or FBAR penalties.

Step five is keeping future years clean: file each year's FBAR, Form 8938 and entity forms on time.

Statute of limitations: why late filers cannot rely on time

If you fail to file Form 8938 or report a specified foreign financial asset, the assessment period for the tax year can stay open until three years after you file the form, and omitting more than $5,000 of related income extends it to six years. Form 3520 instructions state that the assessment period for events reported on Parts I through III will not expire before three years after the required information is reported. Silence does not close the year.

A worked example

Rohan moved to Naperville in 2021 and kept $60,000 across two Indian savings accounts and a fixed deposit. He did not file an FBAR for 2021 through 2025 and learns of the rule in October 2026. Under a theoretical non-willful calculation, five FBARs at $16,536 would be $82,680, but the IRS manual caps total non-willful penalties at 50 percent of the highest aggregate balance, so exposure could not exceed $30,000. If Rohan qualifies for the domestic streamlined procedure, the cost would be 5 percent of the highest aggregate balance, or $3,000, plus any tax on previously unreported interest. All numbers are hypothetical and are not predictions, and each case turns on its facts.

Mistakes to avoid

• Assuming a zero-balance or no-income account is exempt from reporting.
• Filing amended returns without the matching information returns.
• Making a "quiet" correction that conflicts with a later IRS inquiry.
• Treating a certification of non-willfulness lightly.
• Ignoring a notice because the penalty looks small; continuing penalties follow if the IRS notice is not answered within 90 days.
