FBAR refers to Form 114, Report of Foreign Bank and Financial Accounts, that must be filed with the Financial Crimes Enforcement Network (FinCEN), which is a bureau of the Treasury Department. The form must be filed electronically and is only available online through the BSA E-Filing System website.
Who needs to file an FBAR? Taxpayers with an interest in, or signature or other authority over, foreign financial accounts whose aggregate value exceeded $10,000 at any time during 2017 generally must file. For more on filing requirements, see Current FBAR Guidance on IRS.gov.
The FBAR filing requirement is not part of filing a tax return. The FBAR Form 114 is filed separately and directly with FinCEN.
FBAR filings have surged in recent years, according to data from FinCEN. FBAR filings exceeded 1 million for the first time in calendar year 2014 and rose nine of the last 10 years from about 280,000 back in 2005.
