Q. What happens if an account holder is required to file an FBAR and fails to do so?

A. Failure to file an FBAR when required to do so may potentially result in civil penalties, criminal penalties, or both. If you learn you were required to file FBARs for earlier years, you should file the delinquent FBAR reports and attach a statement explaining why the reports are filed late. No penalty will be asserted if the IRS determines that the late filings were due to reasonable cause. Keep copies, for your record, of what you send.
