What must be the total aggregate value of foreign accounts to require FBAR filing?

The requirement to file the Foreign Bank Account Report (FBAR) exists when a U.S. person has a financial interest in or signature authority over one or more foreign accounts, and the total aggregate value of those accounts exceeds $10,000 at any time during the calendar year. This threshold is significant because it helps the U.S. government monitor offshore accounts and combat tax evasion.

When the value exceeds this amount, it triggers the filing requirement, making it clear that the correct answer is indeed $10,000. This figure reflects compliance measures in place and is critical for individuals who have foreign banking relationships. Thus, understanding this threshold is essential for anyone who may have overseas accounts and is subject to U.S. tax regulations.
