What is an "FBAR"?
U.S. Treasury Department Form TD F 90-22.1, Report of Foreign Bank and Financial Accounts.
Am I required to file an FBAR?
If you had a financial interest in or signature power over a offshore account, and that account was worth more than $10,000 on any day last year, you are required to file an FBAR this year.
When is the FBAR due?
It must be received by the US Treasury (not the IRS) by June 30th. There are no extensions of time. Important note for 2012: Because June 30th falls on a Saturday, the FBAR must be received by the Treasury by Friday, June 29th.
What is the penalty for failing to file a required FBAR?
Depending on the circumstances, the civil penalty can be $10,000, $100,000, or 50 percent of the balance in the offshore account at the time of each violation. The civil penalty can easily be greater than the balance in the account. There are also potential criminal penalties.
