Most local investment funds and pension sub-funds qualify as PFICs. No meaningful treaty protection for the most common accounts. Mandatory employer schemes create unavoidable exposure. U.S. persons in these jurisdictions almost certainly need to file Form 8621.
PFIC exposure exists but treaty provisions reduce or eliminate it for some account types. Employer pension contributions may be protected while personal investment funds remain exposed. Filing obligation depends on which specific accounts you hold.
Strong treaty provisions protect the most common local investment structures. Remaining PFIC exposure is typically limited to directly-held foreign funds outside treaty-protected accounts. Filing may not be required if only treaty-protected accounts are held.
