PFIC Rules — Why Foreign Mutual Funds Hurt U.S. Expats
Reviewed by the Fairlight Accounting cross-border tax team — U.S. & Canadian Tax Desks
A passive foreign investment company (PFIC) is any non-U.S. corporation whose income is mostly passive or whose assets mostly produce passive income — a definition that captures nearly every mutual fund, exchange-traded fund, and unit trust organized outside the United States. For U.S. citizens abroad who invest through local banks and brokers, PFIC status turns ordinary investing into one of the most expensive mistakes on a U.S. return.

Why do ordinary foreign funds count as PFICs?
Because a fund's income is dividends, interest, and gains — passive by definition — and its assets are securities. The test is mechanical: 75% or more passive income, or 50% or more passive assets, in any year. A European index fund, a Canadian mutual fund, an Australian managed fund, a U.K. investment trust: all PFICs. Individual foreign stocks are generally not, because an operating company's income is active.
What makes the default PFIC tax so harsh?
Under the default rules, a sale of PFIC shares or an unusually large distribution is treated as an "excess distribution." The gain is spread evenly across every year you held the fund, taxed at the highest ordinary rate that applied in each of those years — not the preferential capital-gains rate — and then charged interest as if the tax had been due back then. Long holding periods make the result worse, not better. On a fund held ten years, the combined tax and interest can consume a large share of the gain.
What has to be reported?
Form 8621, annually, for each PFIC you own above small de minimis thresholds — one form per fund, every year, whether or not you sold anything. The fund itself is also a specified foreign asset for Form 8938 and, if held in a foreign account, counts toward the FBAR threshold. Missing Form 8621 keeps the statute of limitations open on the whole return.
What are the two elections that help?
- Qualified electing fund (QEF). You include your share of the fund's income each year as ordinary income and capital gain, much like a U.S. fund, and later sales get capital-gains treatment. The catch: the fund must provide an annual PFIC information statement, and most retail funds outside North America don't.
- Mark-to-market. For funds traded on a qualifying exchange, you recognize the year's change in value as ordinary income (or a limited loss) each year. No interest charge, no excess-distribution spreading, but gains are taxed at ordinary rates annually.
Both elections generally have to be made in the first year you hold the fund to be fully effective. Electing late usually requires a "purging" election — effectively paying the default tax on built-in gain first.
Are retirement accounts protected?
Sometimes. Funds held inside a foreign retirement plan that is protected by a treaty article, or that meets the IRS's exemption for certain tax-favored foreign retirement trusts, are not subject to PFIC reporting while in the plan. Funds in an ordinary brokerage account, or in a savings plan the treaty doesn't cover, are fully exposed. Which side of that line a specific plan falls on depends on the country and the plan's terms.
What should an expat do instead?
Most U.S. advisers steer clients toward U.S.-domiciled funds and ETFs, held with a U.S. broker that accepts foreign addresses — those are not PFICs and get normal U.S. treatment. The trade-off is that some countries tax U.S. funds unfavorably on their side, and a few local rules penalize non-local funds. The right answer depends on both countries' rules, which is why this decision is worth making before investing, not after.
Frequently asked questions
I only hold a small amount. Do I still file Form 8621?
Not if your total PFIC holdings are under the de minimis thresholds and you received no excess distributions — but you still report the account on the FBAR and Form 8938 if those thresholds are crossed.
My foreign pension fund holds mutual funds. Is that a PFIC problem?
Only if the plan isn't protected. Treaty-covered employer pensions are generally fine; personal savings plans often are not.
Can I just sell everything and start over?
Selling triggers the default excess-distribution tax on all the built-in gain. Sometimes that's still the right move; the calculation decides.
Does Form 8621 apply if I never sold and received no dividends?
Yes, above the thresholds — an annual information report is required even in a quiet year.
