If you hold an account in any foreign bank, you must report it annually to the U.S. Treasury Department. The nature of these accounts can vary from one institution to another. To make things easier for our clients, we have listed certain types of accounts, such as mutual funds, brokerage accounts, and checking or savings accounts, along with other financial assets. Under the Bank Secrecy Act, U.S. residents are required to file a Foreign Bank Account Report (FBAR). If your total balance across foreign accounts is at least $10,000, you must also file FinCEN Form 114.
In all honesty, filing FinCEN Form 114 is compulsory for every U.S. citizen with a foreign bank account. Failure to comply can lead to harsh penalties, which may even include criminal charges.
Be aware that besides FinCEN Form 114, you will also need to file FATCA's Form 8938. However, there are specific criteria that you must satisfy in order to be required to file the FATCA form.
