E-filing is a quick and secure way for individuals to file FBARs. Filers will receive an acknowledgement of each submission. For more information about electronic filing, read the FinCEN news release . Help with electronic filing technical questions is available at BSAEfilinghelp@fincen.gov or through the BSA E-Filing Help Desk at 866-346-9478.Now, you are not allowed to MAIL in the form.
