Hi, requesting your opinion - I plan to file one FBAR non-compliance case through form 3949-A or 211. Here I will report a case of foreign national not filing FBAR but has amounts > $10K in foreign banks. I have his SSN, birth date, phone number, foreign bank account numbers and his yahoo email where he mentions about not filing FBAR. But I do NOT have proof (like bank statements), do not have figures of under reporting and tax loss, do not have account balances (but I think maximum account balance was < $50K).

Do you think this will give IRS enough information to act on it?
