The late FBAR "cover letter": what it actually is in 2026
There is no cover letter. The BSA E-Filing system accepts no attachments with FinCEN Form 114, so the explanation people are searching for goes in the form's own reason-for-late-filing field: a drop-down of common reasons and, when Other is selected, a 750-character statement. Since the IRS withdrew its published penalty-free procedure on 1 July 2026, those 750 characters carry the outcome. This page shows how to write them.
Why there is no letter to attach
Searches for a "delinquent FBAR cover letter" or a "late FBAR sample letter" trace back to the paper-filing era, when practitioners attached an explanatory letter to late forms. Electronic filing ended that. The FBAR (FinCEN Form 114) is filed through the BSA E-Filing system, which accepts no attachments of any kind. The only channel you have at the filing stage is the form's reason-for-late-filing field: a drop-down of common reasons, and a free-text box capped at 750 characters if you select "Other."
A quick scope check before drafting anything: an FBAR is required when the aggregate value of all the foreign financial accounts in which you have a financial interest or signature or other authority, not just bank accounts but also brokerage accounts, mutual funds, and certain pension and insurance arrangements, exceeds $10,000 at any point in the year. If some of those accounts or their income never made it onto your tax returns, stop here and read "When FBAR-only is the wrong route" below, because the statement this page teaches you to write assumes your returns are clean.
What the statement has to do since July 2026
Until 1 July 2026 the IRS published a procedure promising, in writing, that qualifying non-willful filers whose income was reported would pay no penalty for late FBARs. That page was removed without announcement. What survives is IRM 4.26.16.3.11, which directs examiners not to assert a penalty where three things are true: the failure was not willful, it was due to reasonable cause, and the account is properly reported on the late FBAR you are filing. The manual binds examiners as internal guidance, but it does not carry the force of law and confers no rights on taxpayers, so this is relief your statement has to earn on the facts rather than a safe harbor you can point at, though where reasonable cause and proper reporting are established section 5321(a)(5)(B)(ii) bars the penalty outright. The full account of the withdrawal and what survived it covers the case law and the caveats in detail.
The practical consequence: the 750-character statement stopped being a formality. Reasonable cause rewards specific, verifiable facts and is unimpressed by generalities. "I did not know" is a conclusion; the facts that make it credible are what belong in the box.
Three annotated sample statements
The samples below use invented facts. They are drafting patterns, not templates: an examiner reads statements all day, and a copied template with your dates swapped in reads exactly like what it is. Write your own facts in this structure, and have the result reviewed before filing. Educational material, not legal advice.
Sample 1: the preparer knew about the accounts
The strongest pattern available. Under United States v. Boyle, relying on an agent to handle a filing is not reasonable cause, but relying on professional advice about whether a filing was required can be. The fact that carries this statement is that the preparer knew the accounts existed and never raised the FBAR.
I am a US citizen and have lived in Portugal since 2014. From 2015 my returns were prepared by a paid US preparer who received my Portuguese bank statements each year and reported the interest income on Schedule B. The preparer never advised me that FinCEN Form 114 was required. I learned the requirement existed on 3 June 2026, when a new preparer reviewed my situation, and I filed this FBAR and the prior years within six weeks. All income from these accounts was reported and all tax was paid. The failure was not willful and was due to reasonable cause: I relied on a professional who knew the accounts existed and gave no advice that this filing was required.
- "received my Portuguese bank statements each year" puts the accounts in the preparer's knowledge, which is the Boyle advice-side fact. Without it, this is just "my accountant handled everything," which loses.
- "reported the interest income on Schedule B" establishes the income-reported condition and is checkable against the filed returns.
- The discovery date and the six-week response are specific and verifiable, and prompt correction is itself evidence of ordinary care.
- One concluding sentence draws the legal conclusion; everything before it is fact.
Sample 2: a bank FATCA letter was the first notice
Discovery through the bank is common and useful because the trigger is documented and dated by a third party. The letter itself belongs in the reserve file, not attached to the FBAR.
I have lived and worked in Singapore since 2019 and hold one local checking account and an employer pension there. My US returns were filed on time each year and reported all interest and employment income. On 14 April 2026 my bank wrote asking me to confirm my US status under FATCA, which is how I first learned that a FinCEN Form 114 filing existed separately from my tax return. I confirmed the requirement with a US preparer the same month and filed this FBAR and the prior years within 30 days. All income from the accounts was already reported and taxed. The failure was not willful; I acted as soon as I knew the obligation existed.
- The FATCA letter gives the statement a third-party, date-stamped trigger: keep the letter itself for the reserve memorandum.
- Naming the account types matters because the FBAR covers financial accounts broadly, not just bank accounts: the employer pension is exactly the kind of account people miss.
- "filed on time each year and reported all interest" again establishes the reported-income condition in checkable form.
Sample 3: an account you did not know existed
Inherited and family-opened accounts produce genuine no-knowledge patterns. The statement works only if the no-knowledge claim is concrete: who opened it, when you gained control, what it earned.
My mother, a Japanese citizen resident in Osaka, opened a bank account in my name in 2008, while I was living in the United States. I did not open, control, or use the account and did not know it existed. I learned of it on 9 February 2026 while settling her estate. The account is non-interest-bearing and has produced no income. I confirmed the reporting requirement with a US preparer and filed this FBAR within 60 days of learning the account existed. The failure to file earlier was not willful and was due to reasonable cause: before February 2026 I neither knew of nor controlled the account.
- Every element of the no-knowledge claim is tied to a fact that estate records can support: who opened it, when, and when control passed.
- "non-interest-bearing and has produced no income" closes the income question directly. If an unknown account did produce income, the returns need amending and the clean FBAR-only route may not fit; see "When FBAR-only is the wrong route" below.
- 60 days from discovery to filing is the ordinary-care timeline made concrete.
What to leave out
- Bare conclusions. "I was unaware of the requirement" with nothing behind it asserts the thing that needs proving. Facts first, one concluding sentence last.
- Anything your returns contradict. The statement will be read next to your filed returns. If Schedule B answered "no" to the foreign-account question in a year you held the accounts, address the discrepancy with a professional before filing anything, not inside the box.
- Language of choice. "I decided," "I chose not to," "it did not seem necessary" convert an omission into a decision, and willfulness is the one door you cannot afford to open.
- A copied template. The structure here is reusable; the sentences are not. Generic text invites the follow-up questions your statement exists to preempt.
- Anything that will not fit. The box truncates at 750 characters. A statement that ends mid-sentence reads as carelessness on the exact document meant to demonstrate care.
The reserve memorandum
The 750-character box is not the whole showing; it is the visible part. A fuller reasonable-cause memorandum with exhibits, such as the preparer's engagement letter, the date-stamped FATCA letter from your bank, and proof the income was reported, is worth preparing at the same time and holding in reserve. If an examiner later proposes a penalty, that memorandum is what your response is built from. Preparing both together is the difference between a statement and a defense.
When FBAR-only is the wrong route
Everything above assumes your tax returns are complete and correct and only the FBARs are missing. If returns are also behind, or the accounts produced income that never reached a return, the late-FBAR-with-statement route does not fit: the Streamlined Foreign Offshore Procedures exist for exactly that case, with three years of returns, six years of FBARs, a non-willful certification on Form 14653, and no offshore penalty. SFOP is open only where the non-residency test is met, and the domestic track (SDOP) works only by amending original returns already on file, so unfiled years combined with a failed non-residency test fit neither. Start with the cost and eligibility calculator or the route diagnostic.
For scale on what is at stake if you do nothing: the statutory non-willful penalty runs up to $16,536 per annual report (per report, not per account, under Bittner). The willful maximum under 31 U.S.C. ยง5321(a)(5)(C) is the greater of $165,353 or 50% of the balance in the account at the time of the violation. Both are ceilings on what may be assessed rather than amounts that follow automatically, and multiple years can multiply them. The FBAR penalty calculator runs your numbers against those thresholds.
Common questions
Do I attach a cover letter to a late FBAR?
No, because there is nowhere to attach one. The BSA E-Filing system accepts no attachments with FinCEN Form 114. Searches for a delinquent FBAR cover letter trace back to the paper-filing era. Today the explanation goes in the form's own reason-for-late-filing field: a drop-down of common reasons, plus a free-text box capped at 750 characters when you select Other.
What do I select as the reason for filing late?
The drop-down lists common reasons, such as not knowing the filing requirement. If none of them fits your facts, or if your facts deserve more than a canned category, select Other and use the 750-character statement. A specific, dated, verifiable statement in your own facts does more work than any drop-down selection.
How long can the late-filing statement be?
750 characters, including spaces. That is roughly 110 to 130 words, which is a tight budget for the facts that now decide the outcome. Drafting to that limit is the actual work: every clause needs to establish something an examiner can verify.
Can I still use the Delinquent FBAR Submission Procedures?
The published procedure is gone: the IRS removed its Delinquent FBAR Submission Procedures page on 1 July 2026 without announcement or replacement. The underlying relief survives in IRM 4.26.16.3.11, which tells examiners not to assert a penalty where the failure was non-willful, reasonable cause exists, and the account is properly reported on the late FBAR. The manual does not carry the force of law, so this is discretionary relief that turns on the quality of your reasonable-cause showing, not a guarantee.
Should my statement say the failure was non-willful?
State the facts first and let the conclusion rest on them. A bare assertion that you did not know is a conclusion, not evidence. What persuades is the specific, checkable chain: what you understood and why, who knew what, the date and way you learned otherwise, and how quickly you acted. One concluding sentence tying those facts to non-willfulness and reasonable cause is enough.
