The FBAR for calendar year 2025 is due October 15, 2026, and nobody has to ask for that date. Congress set it in Pub. L. No. 114-41, § 2006(b)(11), at “April 15 with a maximum extension for a 6-month period ending on October 15,” and the IRS confirms the extension is automatic.
If you are a U.S. citizen or resident in California and your foreign accounts together topped $10,000 on any day in 2025, file. One report covers every account. If the interest was already on your Form 1040 and Form 540, a late report is paperwork. If it was not, you are picking a cleanup route.
Californians should read the penalty rules closely. The per-report rule for non-willful penalties was decided here first, in United States v. Boyd, 991 F.3d 1077 (9th Cir. 2021), two years before Bittner v. United States, 598 U.S. 85 (2023). It caps less than people assume.
Is the 2025 FBAR really due October 15, and what has to go on it?
Yes. 31 C.F.R. § 1010.306(c) still says reports go to FinCEN “on or before June 30 of each calendar year,” a sentence the 2015 statute overtook and nobody conformed. The trigger sits in 31 C.F.R. § 1010.350(a): a United States person with “a financial interest in, or signature or other authority over” a foreign account. The test is aggregate value above $10,000 at any moment, not at year end. Peak at $10,400 for one July afternoon and you report every account.
“Financial account” reaches past checking. Section 1010.350(c)(3) covers “insurance or annuity policies possessing cash value,” so an endowment policy from Manila counts, and the IRS FBAR Reference Guide adds Mexican Fondos para el Retiro and AFORE accounts. Form 8938 runs on different math, starting at $100,000 at year end or $150,000 at any time for a couple filing jointly here, per the IRS comparison. A Riverside couple can sit under 8938 and far over the FBAR line.
What did the Ninth Circuit decide in Boyd, and what did Bittner add?
Jane Boyd held fourteen United Kingdom accounts and filed one late but accurate FBAR listing all of them. The IRS called that thirteen violations and assessed $47,279. The circuit reversed in Boyd, holding that 31 U.S.C. § 5321(a)(5)(A) “authorizes the IRS to impose only one non-willful penalty when an untimely, but accurate, FBAR is filed, no matter the number of accounts.” On a later record multiplying $10,000 by 272 accounts, Bittner agreed that nonwillful penalties “accrue on a per-report, not a per-account, basis.”
The statute says $10,000, but nobody pays that. 31 C.F.R. § 1010.821 indexes it to $16,536 non-willful and $165,353 willful for penalties assessed on or after January 17, 2025. Those are this year’s numbers too, because OMB Memorandum M-26-11 cancelled the 2026 adjustment when October 2025 CPI data went unpublished.
What changes if I have five or six unfiled years instead of one?
This is where the rule stops helping. One report per year means one penalty per year, and the window in 31 U.S.C. § 5321(b)(1) runs six years from the transaction. Five open years at $16,536 is $82,680 before anyone says the word willful.
Two things push back. The penalty is discretionary. IRM 4.26.16 says the examiner “will either issue the FBAR warning letter, Letter 3800 … or determine a penalty,” and it caps non-willful penalties across all open years at 50 percent of the highest aggregate balance. Reasonable cause is narrow: § 5321(a)(5)(B)(ii) demands reasonable cause and that the balance “was properly reported,” which anyone who omitted the interest cannot show.
Several unfiled years and three weeks until October 15? The route you pick now is hard to change later, and an attorney and CPA can review the accounts and the returns before anything is transmitted.
How do courts in this circuit decide whether a failure was willful?
The Ninth Circuit answered in United States v. Hughes, Nos. 23-15712, 23-15713 (9th Cir. Aug. 21, 2024). Judge Koh wrote that “[f]or purposes of civil penalties, willful violations of the FBAR statute include both knowing and reckless violations,” recklessness meaning a filer who clearly ought to have known there was a grave risk and could have found out easily. It still left two years non-willful, so this is decided year by year.
District courts got there earlier. In United States v. Bohanec (C.D. Cal. Nov. 1, 2016), Judge Pregerson applied a preponderance standard and treated Schedule B, Part III, question 7 as notice; the couple used paid preparers but never asked anyone about the Swiss account. A willful finding moves you to the greater of $165,353 or half the balance under § 5321(a)(5)(C) and (D), and reasonable cause is gone.
Who around Riverside, Chino, and Sacramento actually has this problem?
Not the people in the news stories. The typical file is a family with an account in Guadalajara supporting a parent, NRE and NRO accounts in India left open after a move to Temecula, or accounts in the Philippines, Vietnam, Korea, or China a spouse’s family opened. Coastal property adds a wrinkle: Rev. Rul. 2013-14 held a Mexican Land Trust is not a trust under Treas. Reg. § 301.7701-4(a) where the bank only holds legal title and transfers it at the owner’s direction, so the fideicomiso does not produce Forms 3520 and 3520-A. The peso account funding the predial is a reportable account.
Two groups get caught owning nothing. A business owner with signature authority over a subsidiary’s account in Tijuana or Shenzhen files on that authority alone. An executor who finds a passbook in a safe deposit box faces the decedent’s unfiled years and the estate’s own. The leading case on whether that liability outlives the taxpayer is out of circuit: United States v. Gill, No. H-18-4020 (S.D. Tex. June 30, 2021), holding the statute “is primarily remedial and the claim therefore survives.” No Ninth Circuit opinion settles it.
Does the FTB care, and is there a California version of this?
California has no FBAR, but it has Rev. & Tax. Code § 17041, taxing “the entire taxable income of every resident of this state,” and § 17014, which makes you a resident if you are here for other than a temporary or transitory purpose. That interest belongs on the Form 540 whether or not a 1099 exists.
The state finds out. Section 18622(a) requires reporting a federal change to the Franchise Tax Board “within six months after the date of each final federal determination,” and (b) requires an amended state return within six months of an amended federal one. The state disclosure door is closed: the FTB program under § 19191 runs to qualified entities and their owners, and § 19192 requires a nonresident on the signing date. A Corona resident with an account in Jalisco does not qualify, so the fix is amended returns and a penalty abatement request.
Which cleanup path fits, and what does it cost?
Take a Chino couple, both U.S. citizens, with three inherited accounts at a bank in Guadalajara. The aggregate peaked near $85,000 across 2021 through 2025, the accounts threw off about $2,000 a year in interest that never reached a return, and no FBAR was filed. These numbers are illustrative. On a non-willful examination, five open years at $16,536 is $82,680, cut by the IRM ceiling to half the $85,000 high balance, or $42,500.
Price the Streamlined Domestic Offshore Procedures. The Title 26 miscellaneous offshore penalty is “5 percent of the highest aggregate balance/value of the taxpayer’s foreign financial assets,” aggregating year-end balances for each covered year and taking the highest. So on a best year-end aggregate of $80,000 the penalty is $4,000. Add three amended returns picking up $2,000 of interest each, roughly $1,320 of federal tax, six years of late FBARs, Form 14654, and about $480 of California tax. Under $6,000 against a $42,500 exposure.
The other doors are narrower. If 2025 is the first year over the threshold and the income was reported, file by October 15. If the only defect is the missing report, file late FBARs through the BSA E-Filing System with a reason stated, though the IRS retired its Delinquent FBAR Submission Procedures page in 2026, leaving that to examiner discretion. If the conduct was willful, streamlined is out and the IRS Criminal Investigation Voluntary Disclosure Practice is the route, with Form 14457 preclearance, a six-year period, and no immunity guarantee, covered in an earlier post. A false certification is itself a crime.
| Path | Who qualifies | What you file | Penalty and FTB step |

| Streamlined Domestic Offshore | Non-willful conduct; returns filed for the last 3 years; not under exam | 3 amended Forms 1040-X, 6 years of FBARs, Form 14654 | 5% of highest aggregate year-end balance. Amend Form 540 within 6 months (§ 18622) |
| IRS-CI Voluntary Disclosure | Willful conduct, criminal exposure | Form 14457 Parts I and II, 6 years of returns and FBARs | Civil fraud penalty plus willful FBAR penalty; no immunity guarantee. Amend Form 540 |
Frequently Asked Questions
Is the FBAR due October 15 without requesting an extension?
Yes. Public Law 114-41 set the FBAR due date at April 15 with a maximum six-month extension ending October 15, granted automatically to every filer. There is no form to file. For calendar year 2025, the extended due date is October 15, 2026.
What if I have a foreign account but the balance never reached $10,000?
The test is the aggregate value of all your foreign accounts combined at the highest point during the year, not any single account and not the year-end balance. If the combined peak stayed at or below $10,000, no FBAR is required, but keep the records.
Is the non-willful FBAR penalty per account or per year in California?
Per report, which means per year. The Ninth Circuit reached that result in United States v. Boyd, 991 F.3d 1077 (9th Cir. 2021), and the Supreme Court agreed in Bittner v. United States, 598 U.S. 85 (2023). The adjusted maximum is $16,536 per report, but because the IRS can reach six years under 31 U.S.C. § 5321(b)(1), those yearly amounts stack.
What is the difference between the FBAR and Form 8938?
The FBAR is a Title 31 report filed with FinCEN when foreign accounts exceed $10,000 in the aggregate at any time. Form 8938 is a Title 26 form attached to your return, starting at $100,000 at year end or $150,000 at any time for a couple filing jointly in the United States. Many people owe both.
Do I need to tell the Franchise Tax Board about a foreign account?
There is no California FBAR, but California taxes residents on worldwide income under Rev. & Tax. Code § 17041, so foreign interest and dividends belong on your Form 540. If you amend federal returns, § 18622 requires an amended California return within six months. The FTB disclosure program reaches only nonresidents and out-of-state entities.
What if my parents’ account in Mexico has my name on it?
If the bank will act on your instructions, you have signature or other authority and the account is reportable even if the money is not yours. If you are also a joint owner, you have a financial interest in it. Either way it counts toward your own $10,000 threshold.
