The History of the FBAR: From the Bank Secrecy Act to Today

1970: The Bank Secrecy Act

The FBAR's legal foundation is the Bank Secrecy Act (BSA), signed into law in 1970. The BSA was primarily aimed at combating money laundering and other financial crime by requiring banks and individuals to keep records and file reports that could help law enforcement trace the movement of money — including, specifically, money held in foreign accounts that domestic regulators otherwise had no visibility into.

The reporting requirement that would eventually become the modern FBAR was included in this framework from early on, administered through what was then Form TD F 90-22.1.

The Quiet Decades

For much of the 1970s through the 1990s, FBAR compliance was a low-visibility corner of financial regulation. Awareness among ordinary taxpayers was limited, enforcement resources were modest, and the form was often overlooked even by tax professionals who weren't specifically focused on international issues.

Post-2001: A Higher Priority

Attitudes toward financial transparency shifted substantially after 2001, as anti-money-laundering and counter-terrorism-financing efforts intensified. Enforcement authority for FBAR compliance was delegated to the IRS in the early 2000s, and the agency began treating foreign account disclosure as a meaningfully higher priority than it had been treated previously.

The UBS Case and a Turning Point

A major inflection point came in the late 2000s, when U.S. authorities pursued Swiss banking giant UBS over allegations that it had helped American clients conceal assets from the IRS. The resulting settlement and the associated disclosure of client information sent a clear signal: offshore accounts were no longer effectively invisible to U.S. tax enforcement. In the years that followed, the IRS rolled out a series of voluntary disclosure programs aimed at taxpayers who wanted to come into compliance before being identified through similar means.

2010: FATCA Adds a Second Layer

In 2010, Congress passed the Foreign Account Tax Compliance Act (FATCA), which took a different but complementary approach: rather than relying solely on taxpayers to self-report, FATCA requires foreign financial institutions to report information about U.S.-owned accounts directly to the IRS, and introduced Form 8938 as a taxpayer-side disclosure filed with the federal tax return. This is the origin of the FBAR/Form 8938 overlap we cover in detail in FBAR vs. Form 8938.

The Move to Mandatory Electronic Filing

The FBAR itself also modernized. What was once a paper form (TD F 90-22.1) was replaced by the electronic FinCEN Form 114, filed through the BSA E-Filing System. Electronic filing became mandatory for most filers in 2013, streamlining what had previously been a mail-in process and giving FinCEN a searchable, centralized database of filings.

Where Things Stand Today

The FBAR today sits at the intersection of decades-old anti-money-laundering policy and a much more recent wave of international financial data-sharing. Between FATCA-driven institutional reporting, intergovernmental information exchange agreements, and continued enforcement attention, the practical odds that an unreported foreign account eventually surfaces have risen substantially compared to the form's early decades — which is precisely why understanding the current rules, rather than assuming they still work the way they did in 1990, matters.
