What do I need to know about filing Form 8621 for PFIC reporting?

Form 8621 requires the following for each PFIC: the PFIC's name, address, and identifying number (if available); the class of shares you own and the date acquired; your basis in the shares; the fair market value at year-end; distributions received during the year; gains on dispositions; the election you are making (if any); and the tax computation under the applicable regime. You must file a separate Form 8621 for each PFIC you own, attached to your income tax return.

The good news is that Form 8621 does not have a separate standalone penalty (unlike Form 5471 or FBAR). However, failure to file Form 8621 has two significant consequences: (1) the statute of limitations on your entire tax return does not begin to run for any year in which Form 8621 was required but not filed (IRC 6501(c)(8)); and (2) you may be subject to accuracy-related penalties if PFIC income was not properly reported. To come into compliance, you have several options: file amended returns (Form 1040-X) with Form 8621 attached for each missed year, consider the IRS Streamlined Filing Compliance Procedures (if you qualify as non-willful), or in severe cases, make a voluntary disclosure.

A QEF election must generally be made on the shareholder's timely filed return (including extensions) for the first year the election is effective. A late QEF election requires IRS consent under Treas. Reg. 1.1295-3, which involves demonstrating reasonable cause. The mark-to-market election under IRC 1296 must also be made on a timely filed return for the first year the stock is "marketable stock" in the shareholder's hands. However, you can make a "purging election" under Section 1291(d)(2) — either by deemed sale or deemed dividend — to purge the taint of the Section 1291 regime and then apply the QEF or MTM election going forward. This results in recognizing all gain (or including all E&P) as of the purge date but allows cleaner treatment in future years.

Step 1: Gather year-end fair market values, distributions received, and any disposition information for each PFIC for all open years. Step 2: Compute the Section 1291 tax (if no election was or will be made) or model the QEF/MTM alternatives. Step 3: Prepare Form 8621 for each PFIC for each year. Step 4: Consider the Streamlined Filing Compliance Procedures if you have been a non-willful non-filer — this program allows filing amended returns (or delinquent returns) without penalties. Step 5: File and pay any tax due. Working with a tax professional experienced in international compliance is strongly recommended.

Once you are in compliance, file Form 8621 every year you hold PFIC shares, even if there are no distributions or dispositions. If you make a QEF or MTM election, include the annual income in your return. Keep records of your basis, holding period, and all prior-year computations, as these are needed for future disposition calculations. If the PFIC is a foreign mutual fund, consider whether selling it and reinvesting in a U.S.-registered fund would be simpler — many U.S. persons ultimately divest from PFICs due to the ongoing compliance burden and punitive tax treatment.
