A separate Form 8621 must be filed for each PFIC in which stock is held.

A taxexempt organization that is not taxable under section 1291 may not make the election. In addition, a taxexempt organization that is a member of a domestic pass-through entity is not subject to a QEF election made by the pass-through entity.The income from Qualified Electing Fund (QEF), presented in the statement is calculated per 10,000 CBFI owned.

In a chain of ownership, only the first U.S. person that is a direct or indirect shareholder of the PFIC may make the election.
