I'm late on FBARs. Do I just file them, or do I need Streamlined?

If your US returns were filed, the income reported, and only the FBARs are missing, you file the late reports yourself through FinCEN’s BSA E-Filing System with a reason attached. That’s the whole job, as long as FBARs are all you missed; a missing Form 8938 is its own track. Streamlined is for returns that were wrong or never filed. The IRS took down the page promising no penalty on this fact pattern. The reasonable-cause standard behind it still holds.

Never filed US returns? Start with the never-filed catch-up guide. Already facing an assessed penalty, or need to compare all five resolution routes side by side? The FBAR penalty decision tree maps every path.

Which late-FBAR path is actually mine?

It turns on whether the income on those accounts was already reported on a filed US return. If it was, only the reports are missing, you file them through FinCEN, and no penalty applies where the IRS determines reasonable cause. If it wasn’t, the returns need fixing too, which is Streamlined. If the IRS has contacted you, stop there. You can also run your own facts through the catch-up path finder.

Your situation	The path	What you file	Exposure
Income reported and tax paid, only FBARs missed, no IRS contact	File the late FBARs directly	Each missed year on FinCEN Form 114 through BSA E-Filing, with a reason	No penalty if the account is properly reported and the IRS determines reasonable cause
An FBAR was filed but accounts or values were wrong	Amend the report	A fresh report with the submission type marked as an amendment. FinCEN tells an individual filer to “fill out a new FBAR completely and check the Amend box in Item 1”, then supply the prior report’s BSA Identifier (FinCEN, FBAR Line Item Filing Instructions)	Same reasonable-cause analysis; the examiner manual’s non-willful test also wants accurate delinquent or amended FBARs filed
Unreported foreign income plus missed FBARs, and in any one of the three return years you had no US abode and 330 full days outside the US. One qualifying year out of the three is enough. If you’re neither a citizen nor a green-card holder, that year is tested on failing substantial presence instead	Streamlined Foreign Offshore	Three years of returns, six years of FBARs, Form 14653	No FBAR or return penalties for compliant eligible filers
Same, but no single one of those three years clears that test. Living in the US today doesn’t decide it by itself	Streamlined Domestic Offshore	Amended returns, delinquent FBARs, its own certification	5 percent Title 26 miscellaneous offshore penalty. Charged one time on the highest single covered year’s year-end aggregate, counting assets that should have been reported but weren’t, plus any reported while their income wasn’t
The miss wasn’t honest	Neither streamlined path	Voluntary Disclosure Practice territory, counsel first	The willful ceiling, counted per account per year, subject to examiner mitigation
Civil exam opened, or Criminal Investigation involved	None of the above	Stop and get representation	Streamlined eligibility is gone regardless of the subject

• Quiet filing versus the named procedures, including what a prior amended return costs you

What happened to Delinquent FBAR Procedures?

You can still end up with no penalty. The difference is you’re arguing for it now instead of qualifying for it, because the IRS deleted the page that promised it. A promise became a determination. What survives is the statute’s reasonable-cause exception and the same language in the IRS’s FBAR reference guide, neither new.

Checked July 23, 2026	Before	After
The IRS’s Delinquent FBAR Submission Procedures page	Live, promising no penalty on two conditions: the income was reported and the tax paid, and you hadn’t already been contacted about an exam or a request for delinquent returns. Still up in the June 23, 2026 archive capture	HTTP 404. Dead in the July 16, 2026 capture and on a live check July 23, 2026
The IRS’s list of offshore compliance options	Four routes, including “Delinquent FBAR submission procedures”, as late as the May 26, 2026 capture	Three routes. That entry is gone

It promised the IRS “will not impose a penalty … if you properly reported on your U.S. tax returns, and paid all tax on, the income …” (archived capture). What survives is 31 U.S.C. 5321(a)(5)(B)(ii) and its two conditions:

• The violation was due to reasonable cause.
• The balance in the account was properly reported.

Publication 5569 names the decider: no penalty “if the IRS determines the FBAR violation was due to reasonable cause” (IRS, Publication 5569). The examiner manual still runs a Delinquent FBAR Filing Procedures section telling staff not to assert a penalty on those facts, though that’s internal guidance you can’t file on.

When do I need Streamlined vs delinquent?

When income wasn’t reported. Late FBARs do nothing for a return, so if yours understated income or were never filed, the streamlined procedures cover both. Which streamlined route applies turns on the non-residency test, and that test is met if any one of the three return years qualifies rather than all three, so recent time in the US doesn’t by itself close the foreign route. What a streamlined package actually costs covers the fee side.

• Abroad, if you’re a US citizen or a green-card holder: you meet the requirement “if, in any one or more of the most recent three years for which the U.S. tax return due date … has passed, the individual did not have a U.S. abode and the individual was physically outside the United States for at least 330 full days”. One qualifying year out of the three is enough, so a run of years spent mostly in the US doesn’t close this route. An eligible filer who “complies with all of the instructions outlined below will not be subject to” return, information return or FBAR penalties (IRS, U.S. taxpayers residing outside the United States).
• Abroad, if you’re neither a citizen nor a green-card holder: the 330-day count isn’t your test. You meet the requirement “if, in any one or more of the last three years for which the U.S. tax return due date … has passed, the individual did not meet the substantial presence test of IRC section 7701(b)(3)” (IRS, U.S. taxpayers residing outside the United States). Same one-of-three structure, different test.
• In the US, meaning no one of those three years qualifies under whichever of the two tests is yours: a penalty “equal to 5 percent of the highest aggregate balance/value of the taxpayer’s foreign financial assets that are subject to the miscellaneous offshore penalty during the years in the covered tax return period and the covered FBAR period” (IRS, U.S. taxpayers residing in the United States).

Don’t read “subject to” as a let-off. An asset is in the base for any year it should have been reported on an FBAR or Form 8938 and wasn’t, or was reported while its income wasn’t. What it limits is the count: the IRS aggregates year-end values per covered year and takes “the highest aggregate balance/value from among those years,” so 5 percent is charged once.

How much penalty exposure am I looking at?

For a non-willful violation the manual’s default is one full penalty per report, but on reasonable cause plus an accurate late filing it should not be imposed at all, and even otherwise the total is capped at 50 percent of your highest aggregate balance across all open years. Then the ceilings: $16,536 per report non-willful, the greater of $165,353 or half the balance willful.

Violation	Statutory ceiling	Adjusted maximum for penalties assessed on or after January 17, 2025 (no adjustment issued since FinCEN’s rule that set them; 31 CFR 1010.821 still carried both at its July 22, 2026 issue)	How it counts
Non-willful	$10,000 per violation	$16,536	One penalty per report, so one per year. Examiner guidance caps the total across all open years at 50 percent of the highest aggregate balance of the accounts the violations relate to (IRM 4.26.16.5.4.1)
Willful	Greater of $100,000 or 50 percent of each account’s balance	Greater of $165,353 or 50 percent of each account’s balance	Per account, per year, so the hypothetical’s 3 accounts over 4 years is 12 maximums, about $1,984,236, though that’s a statutory maximum and not a bill. Examiner guidance caps the willful total at 100 percent of the highest aggregate balance of the accounts the violations relate to, across all open years, which on the same $43,000 is $43,000 (IRM 4.26.16.5.5.3). Where that balance stayed under $50,000 in the year, the Level I mitigation guideline is the greater of $1,000 per year or 5 percent of it if you qualify, allocated across the year’s violations
Reasonable cause	No penalty where the violation was due to reasonable cause and the balance was properly reported	n/a	Non-willful violations only

In Bittner the Supreme Court held the $10,000 non-willful maximum “accrues on a per-report, not a per-account, basis.”

Does anyone actually get penalized for late FBARs?

There’s no published rate, and the IRS commits to nothing beyond “assertion of penalties depends on facts and circumstances.” Its examiner manual (IRM 4.26.16) pulls the number well below the statutory ceilings, and its three limits are below. Every line of it is guidance the IRS writes to its own examiners, so it binds nobody.

• Non-willful: the penalty “should not be imposed” on reasonable cause plus accurate late or amended FBARs, and the total will “in no event” exceed “50 percent of the highest aggregate balance … for the years under examination” (IRM 4.26.16.5.4.1).
• Willful is capped too, same base at double the rate: “in no event” more than “100 percent of the highest aggregate balance of all foreign financial accounts to which the violations relate,” across all open years (IRM 4.26.16.5.5.3).
• Willful mitigation below that isn’t automatic. It needs four things: a clean criminal-tax and FBAR-penalty history for ten years, no illegal-source money, cooperation, and no civil fraud penalty. Meet all four and the table’s Level I guideline applies; miss them and the total is still capped at half the highest balance of the unreported accounts, “regardless of the number of willful violations” (IRM 4.26.16.5.5.3).

What counts as reasonable cause for a late FBAR?

The standard is ordinary business care and prudence: a person has reasonable cause “when he committed that violation despite an exercise of ordinary business care and prudence” (IRM 4.26.16, IRS Publication 5569). The examiner manual tells IRS staff to weigh “all the facts and circumstances of each case” rather than applying a checklist, but the factors that show up in exam guidance and court decisions fall into four patterns.

• Reliance on a tax professional who handled your returns but never mentioned FBARs. This is the single most common reasonable-cause argument for Canadians filing US returns through a preparer who didn’t flag FinCEN reporting. The reliance has to be reasonable: you gave the preparer complete information, and the preparer had the qualifications you’d expect.
• Genuine ignorance of the requirement despite ordinary care. The FBAR is filed separately from the tax return through a different agency (FinCEN rather than the IRS), it isn’t mentioned in most commercial tax software, and it has no line on the 1040 itself. For first-time filers, immigrants, and dual citizens whose only foreign accounts were ordinary bank accounts in Canada, this pattern is common and well-documented.
• You filed as soon as you learned of the requirement. Prompt correction after discovery cuts in your favor. The longer the gap between learning about FBARs and filing, the harder the argument gets.
• The accounts held ordinary balances (chequing, savings, registered plans) with income already on the return. This doesn’t excuse the late filing on its own, but it undercuts any suggestion of willful avoidance.

What doesn’t establish reasonable cause: “I didn’t know” when you signed a Schedule B that asks whether you have authority over a foreign financial account, or willful avoidance of learning about the requirement.

How to write the reasonable-cause explanation

You get 750 characters in the FinCEN filing system. That’s about four sentences. Pick a reason from the drop-down or select “other”, and Publication 5569 describes the box as room to “enter up to 750-characters … to explain the late filing” (IRS Publication 5569).

Structure it around four facts: (1) what you knew about the FBAR requirement and when, (2) why you didn’t know earlier (your preparer didn’t mention it, you’d never encountered the form, or you reasonably believed registered Canadian accounts weren’t reportable), (3) how you discovered the requirement, and (4) that you filed as soon as you learned. Specifics beat contrition. “I apologize” is not a fact. “My CPA prepared my returns from 2019 through 2024 and did not advise me of the FBAR requirement; I learned of it in August 2026 from an online guide and am filing immediately” is.

There is no separate cover letter for individual filers. FinCEN’s BSA E-Filing system for individuals does not accept attachments alongside the report, so the 750-character box IS the reasonable-cause statement. If you’re filing through a preparer using a BSA E-Filing account (the batch route), a cover letter can accompany the submission, but for self-filers the box is all you get.

Do I need an accountant to file a late FBAR?

If it’s just FBARs and the returns are already correct, many people file the late reports themselves. The FinCEN system walks you through it. The part that’s worth paying for is the reasonable-cause explanation, because that’s what the IRS evaluates when deciding whether to assert a penalty. If the accounts are small and the story is simple (one Canadian bank account, preparer never mentioned it), a well-written 750 characters is the whole job. If the balances are large, the years are many, or the returns need fixing too, get help, because that’s streamlined territory.

What closes the door on filing the late FBARs yourself?

Two things: contact from the IRS, and willfulness. You should “file late FBARs as soon as possible to keep potential penalties to a minimum,” but only “if the IRS hasn’t contacted you about a late FBAR and you’re not under civil or criminal investigation by the IRS” (IRS, Report of Foreign Bank and Financial Accounts). Once a letter arrives, stop. The reasonable-cause exception doesn’t reach willful violations either, so if the accounts were kept quiet on purpose, talk to counsel first.

• Both streamlined routes require certifying the failure “was due to non-willful conduct” (IRS, Streamlined filing compliance procedures), and a civil exam of any year ends that eligibility (never-filed catch-up guide).

Can I file FBARs for previous years?

Yes. Late FBARs go through FinCEN’s BSA E-Filing system with a reason for the delay; no permission or approval needed. The lookback is six years: the IRS can assess a penalty “at any time before the end of the 6-year period beginning on the date of the transaction” (31 U.S.C. 5321(b)(1)), and streamlined asks for six years. Rarely a reason to file more. Select a reason from the drop-down, write the explanation in the 750-character box, and submit. If the income was already reported and FBARs are all you missed, that’s the whole fix.

What should I do next?

Build the account list first: every foreign account, its peak balance, the year. That tells you which years crossed $10,000 and how many reports you owe. Then check the returns, the fork between FBARs alone and streamlined. Each missing year goes through FinCEN’s filing-late page, which lets individuals file “without registering for an BSA E-Filing account”. The part worth paying for is the reasonable-cause explanation, the thing the IRS now decides. If the returns turn out to be missing too, and not just the reports, that’s the larger job: what a full catch-up involves.
