What Happens If You Forget to File FBAR?

You may be subject to significant penalties and even criminal charges for not filing an FBAR, but in some cases, you can file your late FBAR forms and get back into compliance with minimal penalties and no criminal risk. The consequences depend on why you didn't file the FBAR, whether you had unreported income, if you exercised ordinary caution, and how you get back into compliance. To protect yourself from the worst risks, use TaxCure to find an FBAR-experienced tax professional today. 

Key takeaways

• The IRS discovers unfiled FBARs through reports from foreign banks and by audit or examining taxpayers' returns and finances.
• There's an automatic six-month filing extension, but after that, there's a risk of penalties for failure to file. 
• As of July 2026, the IRS no longer guarantees penalty relief for taxpayers who file late FBARs that aren't associated with unreported income. In the past, this was covered under the delinquent submission procedures. 
• The streamlined compliance procedures can help you get caught up and minimize penalties if you have unreported income and unfiled FBARs.
• Talk with a tax professional about getting into compliance and avoiding FBAR penalties. 

How Does the IRS Know That You Forgot to File an FBAR?

The IRS finds unfiled reports by checking FBARs against reports from foreign financial institutions. The agency also discovers unreported FBARs through audits, criminal investigations, or due to foreign income reported on your tax return without a corresponding FBAR.

Foreign financial institutions send reports about accounts owned by U.S. residents and citizens to the IRS or to their federal government, which then shares the details with the IRS. The Foreign Account Tax Compliance Act (FATCA) has required foreign financial institutions to follow this rule since 2010, and institutions that don't comply are subject to a 30% withholding tax on U.S. source payments and investments.

Prior to FATCA, FBAR reporting compliance was extremely low. Only about 20% or fewer of the people who were supposed to file FBAR were doing so. Many of these people were never caught, and because of that, the IRS labeled not filing an FBAR as one of its dirty-dozen tax scams. 

How the IRS Contacts People About Unfiled FBAR

Once the IRS realizes that you have forgotten to file your FBAR, the agency will send you Letter 4265 (FBAR Appointment Letter). Then, the IRS will request information about your foreign accounts and have you schedule a time to talk with an examiner on the phone. During this conversation, you get to explain why you forgot to file the FBAR. Your response can dictate whether the examiner lets you file under the streamlined filing compliance procedures or decides to pursue penalties for willful failure to file FBARs. Because so much hinges on these meetings, consider working with an experienced tax professional or a tax attorney. 

What to Expect After Your FBAR Examination

If the examiner thinks you have reasonable cause for not filing, they may just let you take care of the delinquent FBARs without assessing a penalty. In that case, the IRS will send you Letter 3800 (Warning for Report of Foreign Bank and Financial Accounts (FBAR) Apparent Violations). You will only get this letter if the IRS is not assessing any FBAR penalties against you. In some cases, you may incur penalties for some years but not for others.

If the examiner decides to assess non-willful penalties on your account, the IRS may send you Letter 3708 (Notice and Demand for Payment of FBAR Penalty). You may also receive Notice 1330 (Information on Making FBAR Penalty Payment by Check). Note that the IRS sends several different letters and notices. These may not be the exact letters that you receive. 

As of 2026, the maximum penalty for non-willful violation is $16,536 per year, but the examiner can assess lower penalties at their discretion. Willful FBAR penalties are a maximum of $165,353 or 50% of the balances in your foreign accounts. If the examiner decides to assess willful penalties, the FBAR Counsel will review your case. You have the right to appeal, but you should hire a tax attorney to get you through the battle. Cases involving willful FBAR penalties often go through several appeals in the court system. 

Dealing With Late FBARs Without IRS Contact: What If the IRS Doesn't Notice Your Unfiled FBAR?

If the agency hasn't contacted you yet, you may just want to file your late FBARs and hope for the best. Often, the IRS doesn't impose penalties as long as there's no unreported income or willful failure to file, but because the potential penalties are so high, you may want to reach out to a tax professional first. The IRS's website says to file late reports but also reminds taxpayers of the penalty risk.

Here's an overview of dealing with late FBAR reports in various situations: 

• Your FBAR is only a few months late. The FBAR is due April 15th, but the automatic extension gives you until October 15th, so if you're only a few months behind, you can file the report without worrying about consequences. 
• You didn't file due to a natural disaster. If the IRS extended your income tax return filing deadline due to a federally declared natural disaster in your area, the extended deadline also applies to your FBAR requirement. The Financial Crimes Enforcement Network (FinCEN) posts information about FBAR deadline extensions due to natural disasters on its website. 
• You filed your taxes correctly but forgot the FBAR. You can just file the late FBAR, but you may be at risk of penalties. In the past, the IRS's delinquent filing submission procedures offered a guarantee against penalties in this situation, but the IRS removed those administrative guidelines from its website in July of 2026. 
• You didn't report income from the foreign accounts. Then, you'll need to amend your returns and file the FBARs. A quiet disclosure is when you do this without notifying the IRS, but it offers no protection. You may want to use the streamlined filing procedures, which limit your penalties to 5% of your highest balance in the years related to the disclosure.
• You didn't file the FBARs in an attempt to evade tax. When criminal intent was involved, you may qualify to get back into compliance through the IRS's CI Voluntary Disclosure Practice, but you should always work with an attorney for these cases. 

Be aware that the streamlined filing procedures and just filing a late FBAR are only available options if you're not under audit or dealing with a criminal investigation. The rule applies even if the audit is for a different year or the criminal investigation is on a separate issue. 

IRS Streamlined Filing Compliance Procedures for Late FBARs

If you forgot to file the FBAR and also forgot to report income from your foreign accounts on your tax return, you might be able to take care of the FBAR through the streamlined filing option.
There are Streamlined Domestic Offshore Procedures and Streamlined Foreign Offshore Procedures depending on whether you live in the United States or abroad. 

To use the streamlined program, you must meet the following requirements:

• You have a Social Security Number or a Tax Identification Number. 
• Your failure to file the FBAR was not willful. It may have been due to negligence, a mistake, or any good-faith misunderstanding of the rules. 
• You are not under an IRS civil examination, even if the IRS is investigating you for an unrelated issue. 
• You are not under criminal investigation from the IRS. 

Typically, you'll need to amend the last three years of tax returns to report income from your foreign accounts, pay any additional tax due, and file the FBAR for each of the years in question. 

The only difference is that people living in the United States should file Form 14654 (Certification by U.S. Person Residing in the United States for Streamlined Domestic Offshore Procedures). People who live abroad should file Form 14653 (Certification by U.S. Person Residing Outside of the United States for Streamlined Foreign Offshore Procedures). 

These forms certify that you've completed the streamlined delinquent FBAR process steps and that your failure to file on time was not willful. You can find them on the forms and publications page of the IRS's website. 

Willful Failure to File FBAR

Typically, if someone acts willfully, they didn't forget to file their FBAR. They deliberately (willfully) choose to ignore the reporting requirement. However, willful doesn't just apply to people who purposefully and knowingly ignored the reporting requirement. Willfulness can also include cases where you purposefully avoided learning about a tax requirement. This is called willful blindness. Reckless behavior can also be considered willfulness. For instance, if you sign your return and answer the question on Schedule B about the foreign bank account reporting requirement but still don't file an FBAR, you may have acted recklessly. 

If you believe you committed a crime or have criminal exposure due to willful failure to file the FBAR, you may need to file your FBAR through the IRS Criminal Investigation Voluntary Disclosure Practice. This program does not necessarily prevent you from facing criminal prosecution, but when you make a voluntary disclosure, the IRS is often less likely to recommend criminal charges. 

FAQs on Unfiled FBARs & Getting Back Into Compliance

Is there an FBAR extension for 2026?

Yes, every year, the deadline automatically goes to October 15th or the next business day if that date falls on a weekend or holiday.

How do you get an FBAR filing extension?

You don't have to apply for an extension. The six-month extension applies automatically every year.

What happens if I file an FBAR late?

If the IRS finds out first, they'll contact you for an examination to decide whether to assess FBAR penalties against you. If you file the late report before the IRS reaches out, you may be at risk of penalties. Talk with a tax professional to see if you should simply file late or use an established IRS late filing procedure. 

How late can you file an FBAR?

You can file FBARs up to six months late with no consequences. After that, you can file an FBAR from any previous year, but you may face penalties.

What's the statute of limitations on late FBAR reports?

No, there's no statute of limitations on unfiled FBARs. The IRS or FinCEN can assess penalties at any point for any year where you don't file an FBAR.
