Implementation Guide for Tax Professionals
Identify PFIC Holdings
A PFIC is a foreign corporation where: (1) 75%+ of gross income is passive (income test); or (2) 50%+ of assets produce passive income (asset test). Common PFICs: foreign mutual funds, ETFs domiciled outside the U.S., and foreign holding companies. Check all foreign investments — even small holdings in foreign funds can be PFICs. [IRC §1297]
Choose the Tax Regime
Three tax regimes available: (1) Default (excess distribution method) — punitive, avoid if possible; (2) QEF election — requires PFIC to provide annual information; (3) Mark-to-market election — available for marketable PFICs. The QEF and MTM elections must generally be made in the first year the taxpayer holds the PFIC. Late elections may be available with IRS consent.
Make the Appropriate Election
QEF election: file Form 8621 with the return for the first year of PFIC ownership. The PFIC must provide a PFIC Annual Information Statement. MTM election: available for PFICs traded on a recognized exchange. File Form 8621 annually. Include annual MTM income/loss in ordinary income. The election is irrevocable without IRS consent.
Report Annual PFIC Income
File Form 8621 annually for each PFIC if: (1) a distribution is received; (2) PFIC stock is disposed of; (3) a QEF or MTM election is in effect; or (4) the PFIC value exceeds $25,000 ($50,000 MFJ). Failure to file Form 8621 tolls the statute of limitations for the entire tax return — a significant risk for clients with unreported PFIC holdings.
Frequently Asked Questions
What is a Passive Foreign Investment Company (PFIC)?
A PFIC is a foreign corporation that meets either: (1) the income test — 75%+ of gross income is passive (dividends, interest, rents, royalties, capital gains); or (2) the asset test — 50%+ of assets produce passive income. Common PFICs: foreign mutual funds, ETFs domiciled outside the U.S., and foreign holding companies. Even small investments in foreign funds can be PFICs. [IRC §1297]
What is the default PFIC tax regime?
Under the default regime (excess distribution method), PFIC gains and distributions are subject to punitive tax treatment: (1) the gain/distribution is allocated ratably over the holding period; (2) each year's allocation is taxed at the highest ordinary income rate for that year (currently 37%); (3) an interest charge is added for each year. This regime is extremely punitive and should be avoided.
What is the QEF election?
A Qualified Electing Fund (QEF) election requires the PFIC to provide annual information to U.S. shareholders. The shareholder includes their pro-rata share of the PFIC's ordinary income and net capital gain each year (whether or not distributed). QEF income is taxed at regular rates (not the punitive default regime). The QEF election must be made in the first year the taxpayer holds the PFIC.
What is the mark-to-market election for PFICs?
The mark-to-market (MTM) election allows U.S. shareholders to include the annual increase in PFIC value as ordinary income (and deduct decreases as ordinary losses, limited to prior inclusions). MTM income is taxed at ordinary rates — not the punitive default regime. The MTM election is available for "marketable" PFICs (traded on a recognized exchange). [IRC §1296]
What are the Form 8621 filing requirements?
Form 8621 must be filed for each PFIC held if: (1) the taxpayer receives a distribution from the PFIC; (2) the taxpayer disposes of PFIC stock; (3) the taxpayer makes a QEF or MTM election; or (4) the PFIC value exceeds $25,000 ($50,000 for MFJ) at year-end. Failure to file Form 8621 tolls the statute of limitations for the entire tax return.
