The FBAR came into effect through the Bank Secrecy Act of 1970, which President Nixon signed on October 26, 1970. The core rule established then — that any U.S. person with foreign financial accounts exceeding $10,000 in combined value at any point during the year must report those accounts to the federal government — has remained unchanged for more than five decades. What has shifted, and shifted dramatically, is who runs the program, how you file, when you file, and what happens if you don’t.
The 1970 Statute
Congress created the foreign account reporting requirement through the Bank Secrecy Act (P.L. 91-508), codified at 31 U.S.C. 5314. The statute directed the Secretary of the Treasury to require U.S. residents and citizens to keep records and file reports whenever they maintain a relationship with a foreign financial institution.1Office of the Law Revision Counsel. 31 USC 5314 – Records and Reports on Foreign Financial Agency Transactions The law responded to the growing use of foreign bank accounts to hide income from the IRS and launder criminal proceeds.
Treasury set the reporting trigger at $10,000 in aggregate value across all foreign accounts, meaning no single account has to hit that number on its own. If the combined peak balances of every foreign account you hold reach $10,000 at any moment during the calendar year, the filing requirement kicks in.2Financial Crimes Enforcement Network.

In 1970 dollars it was worth roughly $75,000 in today’s terms; today it captures a much wider pool of account holders than Congress originally faced.
Sporadic Enforcement Until the PATRIOT Act
For its first three decades, the FBAR was a largely ignored obligation. That changed after September 11, 2001. The USA PATRIOT Act of 2001 didn’t create the reporting rule, but it put real weight behind it. Section 361 directed the Treasury Department to study and improve compliance with the existing reporting rules under 31 U.S.C. 5314 and to produce regular reports to Congress on how the system was working.1Office of the Law Revision Counsel. 31 USC 5314 – Records and Reports on Foreign Financial Agency Transactions The post-2001 focus on tracking cross-border money flows for national security reasons turned FBAR from paperwork into a genuine enforcement priority.
Congress also strengthened the civil and criminal penalty framework under 31 U.S.C. 5321, establishing a two-tier system that distinguishes between people who make honest mistakes and those who deliberately hide accounts.
Transfer to FinCEN and a New Form
The IRS originally handled FBAR intake and processing. Administration eventually shifted to the Financial Crimes Enforcement Network, a Treasury bureau focused on analyzing suspicious financial activity across all sectors. In 2003, FinCEN formalized its enforcement authority over FBAR through a regulatory amendment published in the Federal Register, though the IRS retained a delegated role in examining taxpayers and assessing penalties. The split reflects the dual nature of the form: it’s both a financial intelligence tool and a tax compliance mechanism.
The reporting form itself was renamed as part of the transition. The old Treasury Form TDF 90-22.1 gave way to FinCEN Form 114, reflecting the new agency’s central role.3Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) The underlying obligation stayed the same.
Mandatory Electronic Filing in 2013
Treasury mandated electronic filing for most Bank Secrecy Act reports beginning July 1, 2012, but granted a specific exemption for FBARs until June 30, 2013.4Financial Crimes Enforcement Network. Mandatory E-Filing FAQs Starting July 1, 2013, all FBARs had to be submitted electronically through the BSA E-Filing System. Decades of paper forms mailed to the Treasury ended, and FinCEN could cross-reference account data with other financial intelligence in near-real time.
The 2015 Deadline Change
The FBAR deadline used to fall on June 30. The Surface Transportation and Veterans Health Care Choice Improvement Act of 2015 moved it to April 15, aligning it with the federal income tax deadline, and authorized a maximum six-month extension. FinCEN implemented that extension by making it automatic. If you miss April 15, your deadline moves to October 15 with no need to request it.5Financial Crimes Enforcement Network. Due Date for FBARs
How the Penalties Have Grown
The penalty structure is where the FBAR’s evolution has been most consequential. The base statutory penalties under 31 U.S.C. 5321 break into two categories based on whether the violation was willful:
- Non-willful violations carry a maximum statutory penalty of $10,000 per report, with a reasonable-cause exception that can eliminate the penalty entirely if you can show the failure resulted from reasonable cause and all income was properly reported.6Office of the Law Revision Counsel. 31 USC 5321 – Civil Penalties
- Willful violations carry a penalty equal to the greater of $100,000 or 50 percent of the account balance at the time of the violation.6Office of the Law Revision Counsel. 31 USC 5321 – Civil Penalties
Those statutory base amounts are now significantly higher after inflation adjustments. As of the most recent adjustment effective January 17, 2025, the non-willful cap is $16,536 per report, and the willful penalty range is $71,545 to $286,184 before the 50-percent-of-balance calculation comes into play.7eCFR. 31 CFR 1010.821 – Penalty Adjustment and Table
Criminal penalties apply to willful violations and can reach $250,000 in fines and five years in prison. If the violation occurs alongside another federal crime or as part of a pattern involving more than $100,000 in a twelve-month period, the maximums rise to $500,000 and ten years.8GovInfo. 31 USC 5322 – Criminal Penalties
The Bittner Decision (2023)
For years the government assessed non-willful penalties on a per-account basis. Someone with five unreported accounts could face five separate $10,000 penalties for a single year’s missed filing. The Supreme Court shut that approach down in Bittner v. United States, decided February 28, 2023, holding that a non-willful violation is one failure to file a compliant report, not one failure per account. The maximum non-willful penalty is therefore capped at one penalty per annual report, regardless of how many accounts were involved.9Justia U.S. Supreme Court Center. Bittner v. United States The Court was careful to note that willful penalties remain account-specific, so the distinction between willful and non-willful matters enormously in cases involving multiple accounts.
What the FBAR Still Doesn’t Cover
One notable gap in the requirement’s reach concerns virtual currency. As of FinCEN’s December 2020 notice, cryptocurrency held on a foreign exchange is not reportable on the FBAR on that basis alone, though FinCEN has signaled it intends to propose regulations that could change this.10Financial Crimes Enforcement Network. Notice – Virtual Currency Reporting on the FBAR If a foreign exchange also offers traditional financial services such as brokerage or banking, the account can still be reportable on those grounds. More than fifty years after the Bank Secrecy Act, the rules governing what counts as a foreign financial account are still catching up to the ways people hold money abroad.
