The **Delinquent FBAR Submission Procedures** allow you to file late FBARs with no penalty whatsoever, provided two conditions are met: you properly reported on your US tax returns, and paid all tax on, the income from those foreign accounts, and the IRS has not previously contacted you about an income tax examination or a request for delinquent returns for those years. If both hold, you e-file the missing reports through FinCEN's BSA E-Filing System with a short statement explaining why they are late, and the IRS states it will not impose a penalty. If either condition fails, this route is closed to you and you need the Streamlined Filing Compliance Procedures or something more formal. Choosing the wrong one is the single most expensive mistake in offshore compliance.
Why so many Americans in Britain are in this position
The FBAR requirement catches far more people than it was ever popularly understood to catch. You must file FinCEN Form 114 if the aggregate value of your foreign financial accounts exceeded $10,000 at any point during the calendar year. Aggregate, not per account. At any point, not at year end.
For an American living in London, that threshold is met by an ordinary current account and a cash ISA. Add a workplace pension, a Monzo account opened for holidays, a joint account with a British spouse and an old savings account you forgot about, and the aggregate is comfortably over the line without any of it feeling remotely like offshore banking.
The persistent myth is that FBAR is a rule for people with secret Swiss accounts. It is not. It is a reporting rule for anyone with foreign accounts above a modest threshold, and the typical delinquent filer we meet is a salaried professional who moved to the UK, kept filing US returns diligently, declared all their UK interest, and simply had no idea a separate report to a different agency existed. Our complete guide to FBAR and FinCEN Form 114 covers the filing mechanics in detail.
The Delinquent FBAR Submission Procedures: the two conditions, read carefully
The IRS sets out the procedure on its page for the Delinquent FBAR submission procedures. The wording of the penalty relief matters enormously, so it is worth taking it apart.
The first condition is that you properly reported on your US tax returns, and paid all tax on, the income from the foreign financial accounts covered by the delinquent FBARs. This is a question about your Form 1040, not about the FBAR. If the UK bank interest, the dividends, the ISA income and any gains from those accounts all appeared on your returns and the tax was paid, you satisfy it. If any of that income was omitted — even innocently, even in a small amount — you do not.
The second condition is that you have not previously been contacted regarding an income tax examination or a request for delinquent returns for the years in question. This is about timing, and it is unforgiving. The relief is available to people who come forward voluntarily. Once the IRS has opened the conversation, voluntary disclosure is no longer what you are doing, and this door closes.
Both must hold. There is no partial credit and no discretion to be exercised in your favour if one is missing.
The distinction that decides everything: was the income reported?
Almost every real case turns on the first condition, and the answer is more often 'no' than people expect.
Consider a US citizen in Manchester with a UK current account, a stocks and shares ISA and a Vanguard UK fund holding. She filed her 1040 every year and declared her salary and her bank interest. She did not file FBARs, and she did not report the ISA at all because a British colleague told her ISAs are tax-free.
ISAs are tax-free in the UK. They are fully taxable in the US, and a stocks and shares ISA holding non-US funds is almost always a Passive Foreign Investment Company requiring Form 8621. Her income was not properly reported. The Delinquent FBAR Submission Procedures are not available to her, and filing late FBARs alone would leave her exposed while advertising the accounts to the IRS. She needs the Streamlined route. We explain why in our guide to PFIC rules and UK ISAs.
Now consider her colleague, who has the same current account and a UK savings account, declared every pound of interest on his 1040s, paid the tax, and simply never heard of FinCEN Form 114. He satisfies both conditions cleanly. He files the late reports, attaches a truthful explanation, and pays nothing.
The two men look identical from the outside. One has a free fix and one has a five-figure project. The entire difference is whether the income was on the return.
What the penalties look like if you get this wrong
The reason to be careful is the scale of the downside. FBAR penalties are set under 31 U.S.C. 5321 and adjusted annually for inflation.
For penalties assessed in 2026, the non-willful maximum is $16,536 per violation. The willful maximum is the greater of $165,353 or 50% of the account balance at the time of the violation — per violation, per year.
The Supreme Court's 2023 decision in Bittner v. United States materially improved the non-willful position by holding that the penalty accrues per report rather than per account. Before Bittner, a taxpayer with twelve unreported accounts over five years faced sixty violations. After it, five. That is a meaningful reduction, but $16,536 a year for five years is still $82,680 for a paperwork failure on accounts that were fully taxed.
The willful figures are the ones that end careers. Willfulness in this context includes reckless disregard, not merely a considered decision to conceal — and answering 'no' to the foreign account question on Schedule B while holding foreign accounts is evidence that prosecutors and revenue agents use routinely.
How to file: the mechanics
- File electronically through FinCEN's BSA E-Filing System. There is no paper route for delinquent FBARs and no separate submission address.
- File a separate FBAR for each delinquent calendar year. Do not attempt to consolidate several years into one report.
- Select the reason for late filing from the dropdown the system presents, and where the reason is not adequately covered, use the free-text box to give a short, truthful explanation.
- Keep the explanation factual and brief. 'I was unaware of the FBAR filing requirement until my accountant raised it in June 2026' is better than a page of justification.
- Complete the account details accurately, including maximum account value during the year and the financial institution's name and address. Estimated maxima are acceptable if you tick the box indicating the amount is an estimate.
- Save the BSA E-Filing confirmation and tracking number for every year filed. This is your evidence that the submission happened and when.
How many years to file
The FBAR statute of limitations is six years from the due date of the report. In practice, filers under these procedures generally submit the last six years of delinquent FBARs.
Filing more than six years is usually unnecessary and occasionally counterproductive, because it extends the window of information you are volunteering without extending any protection. Filing fewer than six leaves gaps that are visible and invite the question of why they are missing.
Note that this six-year window is different from the three-year period covered by the Streamlined Filing Compliance Procedures for tax returns, and different again from the six years of FBARs that Streamlined also requires. The mismatch between return years and FBAR years under Streamlined is a frequent source of incomplete submissions.
Delinquent FBAR versus Streamlined: choosing correctly
These are not alternatives you pick between on preference. They address different facts.
The Delinquent FBAR Submission Procedures address one problem only: missing information reports where the tax was right. No amended returns are required, no certification of non-wilfulness is signed, no penalty is paid.
The Streamlined Filing Compliance Procedures address unreported income. They require three years of amended or delinquent tax returns, six years of FBARs, and a signed certification under penalty of perjury that the failures were non-wilful. For taxpayers resident abroad — the Streamlined Foreign Offshore Procedures — the miscellaneous offshore penalty is zero. For those resident in the US, the Streamlined Domestic Offshore Procedures carry a 5% penalty on the highest aggregate year-end value of the unreported assets. The IRS explains the eligibility rules on its Streamlined filing compliance procedures page, and we compare the two versions in our guide to Streamlined Domestic versus Foreign Offshore Procedures.
The decision tree is short. Was all the income reported and taxed? If yes, and the IRS has not contacted you, use the Delinquent FBAR procedures. If no, use Streamlined. If the conduct was wilful, neither is appropriate and you need the IRS Criminal Investigation Voluntary Disclosure Practice and a lawyer, not an accountant.
The mistake of the quiet disclosure
There is a fourth option that people discover on internet forums and that we would urge you to avoid: quietly filing the late FBARs, or quietly amending returns, without using any formal procedure and hoping nobody notices.
The IRS has been explicit for over a decade that quiet disclosures are not an approved route and that taxpayers who make them may be examined and penalised. A quiet disclosure gives you none of the penalty protection of the formal procedures while giving the IRS all of the information. It is the worst combination available.
The Delinquent FBAR procedure is not a formal amnesty programme with an application and an acceptance letter — it is simply the correct way to file late reports, with a stated position on penalties. Using it costs nothing extra compared with a quiet filing. There is no scenario in which quiet is better.
What about missing Forms 8938, 5471 and 3520?
FBAR is not the only information report expats miss, and it is often not the most expensive one.
Form 8938 reports specified foreign financial assets under FATCA and is filed with your tax return rather than with FinCEN. Form 5471 reports interests in foreign corporations. Form 3520 reports foreign gifts and trusts. These carry their own penalty regimes, and the Form 3520 and 5471 penalties start at $10,000 per form per year automatically.
The Delinquent International Information Return Submission Procedures cover these, on a similar logic — reasonable cause, no unreported income, no prior contact. But they are a separate procedure with separate requirements, and the reasonable cause statement carries considerably more weight there than the short explanation an FBAR needs.
If you have missed FBARs, work through the whole picture rather than the one form you have noticed. Our comparison of FBAR versus FATCA reporting sets out which assets land on which form, and the Foreign Earned Income Exclusion calculator will tell you quickly whether the underlying years were likely to have produced a tax liability at all.
Practical points that matter more than they should
- Joint accounts with a non-US spouse are still reportable in full by the US person. The spouse's nationality does not reduce the balance.
- Accounts you have signature authority over but do not own — a parent's account, an employer's account, a club treasury — are reportable, even with no beneficial interest.
- UK pensions are generally reportable on the FBAR. The treaty may defer the tax, but the reporting obligation is separate from the taxation.
- The maximum value during the year is what matters, not the closing balance. An account that briefly held house-purchase proceeds counts at that peak.
- The FBAR deadline is 15 April with an automatic extension to 15 October. No request is needed for the extension.
- Closed accounts still need reporting for the years in which they existed above the threshold. Closing an account does not retire the obligation.
What we do when a client comes to us with missing FBARs
The first step is never to file anything. It is to reconstruct the years — which accounts existed, what their peak balances were, and critically what income they generated and whether that income appeared on the filed returns.
That reconstruction determines the procedure, and the procedure determines everything else. It is entirely routine for a client who arrives certain they need Streamlined to qualify for the free FBAR route, and equally routine for someone hoping for the free route to have an ISA or a foreign fund holding that puts them squarely in Streamlined.
Only once the facts are settled do we file. Filing first and analysing afterwards forecloses options that were available beforehand, and it is not a step that can be undone.
Where we fit
TaxStone is a cross-border practice staffed by Enrolled Agents and ACCA-qualified accountants, working exclusively with Americans in the UK, dual citizens and Green Card holders. Delinquent FBARs are among the most common things we are asked about, and in a substantial proportion of cases the answer is better than the client feared — the income was reported, the IRS has not been in touch, and the fix costs nothing but the filing.
If you have missed FBARs and want to know which procedure applies before you file anything, contact us for a confidential review of the years in question. Nothing in this article is advice on your own facts, and the choice between these procedures should not be made without professional input.
One final point on timing. The second condition — no prior IRS contact — is the one you cannot recover once it is lost. If you know you have a problem, the value of acting now rather than next year is not merely peace of mind. It is the availability of the remedy itself.
