Quick Answer
Beyond FBAR, 8938, 5471, and 3520, U.S. taxpayers with international interests may need to file four additional forms: (1) Form 8865 for foreign partnerships; (2) Form 926 for transfers to foreign corporations; (3) Form 8858 for foreign disregarded entities; and (4) Form 8621 for PFIC investments. The short version is that the international informational return landscape is vast and penalty-heavy. In our experience, missed PFIC reporting (Form 8621) and missed foreign partnership reporting (Form 8865) are the two most common gaps for U.S. investors with international holdings.1
