PFIC Rules 2026: Foreign Funds and Form 8621
The fund a European bank offers a new resident may be entirely sensible for that resident’s neighbours. For an American, the same fund sits inside one of the harshest regimes in the U.S. tax code — and EU consumer law closes the obvious alternative.
For an American, an ordinary European fund falls under the passive foreign investment company rules: under section 1291 an excess distribution or any gain on disposal is allocated rateably across the holding period, taxed at the top rate in effect for each prior PFIC year, and charged section 6621 interest. Each fund needs its own Form 8621 each year.
| Item | Position |
|---|---|
| Statutory origin | The Tax Reform Act of 1986, Public Law 99-514 |
| Default regime | The section 1291 excess-distribution rules, where no election is made |
| Allocation | An excess distribution, or any gain on disposal, is allocated rateably across the holding period |
| Rate applied | The top rate in effect for each prior PFIC year — 39.6% for 2013 through 2017, against a 2026 top individual rate of 37% |
| Interest | Section 6621 underpayment interest is added to the amounts allocated to prior years |
| Disposals | The entire gain is treated as an excess distribution, with none of the 125% cushion that applies to ordinary distributions |
| Filing | A separate Form 8621 for each PFIC, each year |
| IRS burden estimate | About 49 hours per fund per year: roughly 17 hours of recordkeeping, 11 learning the law and the form, and 21 preparing and sending it |
| De minimis relief | 26 CFR §1.1298-1(c)(2) — $25,000 single, $50,000 joint, $5,000 for indirectly held section 1291 stock. It relieves only the section 1298(f) ownership-reporting requirement, and only where there is no excess distribution, gain or qualified electing fund inclusion |
| QEF election | Section 1295 requires a PFIC Annual Information Statement from the fund, which a European manager has no obligation to produce |
| Mark-to-market election | Section 1296 requires marketable stock, regularly traded on an SEC-registered national securities exchange or a market the Secretary has approved |
| The EU side | Under the PRIIPs Regulation (EU) No 1286/2014 a Key Information Document has been required since 1 January 2018. The requirement bites on making a product available, not on continued holding |
A regime most Americans abroad meet by accident
The passive foreign investment company rules entered the code through the Tax Reform Act of 1986, Public Law 99-514, and were aimed at deferral through offshore funds. They were not written with a schoolteacher in Lisbon and a €30,000 index fund in mind. They apply all the same.
The mechanics are set out in section 1291. An excess distribution — and any gain on disposition — is allocated rateably to each day of the holding period. The amounts allocated to prior years in which the company was a PFIC are then taxed at the highest rate in effect under section 1 or 11 for each of those years, and an interest charge is added using the underpayment rates and method of section 6621.
Two points of precision matter here, and generic summaries usually get both wrong. First, the highest-rate-plus-interest treatment reaches only the slices allocated to prior PFIC years; the current-year slice and any pre-PFIC period are simply included in ordinary income without an interest charge. Second, the applicable rate is the top rate in effect for each of those prior years, not today’s rate — so a holding running back through 2013 to 2017 picks up 39.6% for those years, while the top individual rate for 2026 is 37%, applying above $640,600 for a single filer and $768,700 for a married couple filing jointly.
Selling is where the regime bites hardest. Section 1291(a)(2) applies the excess-distribution rules to gain on a disposition, and the Form 8621 instructions state that the entire gain on disposing of a section 1291 fund is treated as an excess distribution — with none of the 125%-of-the-prior-three-years cushion that applies to ordinary distributions.
The forms, and the exception that does less than it appears
A separate Form 8621 is required for each PFIC held, directly or indirectly, each year. The IRS publishes its own burden estimate for that form: roughly 17 hours of recordkeeping, 11 hours learning the law and the form, and 21 hours preparing and sending it — close to 49 hours in total, per fund, per year.
There is a de minimis exception, and it is narrower than it is usually described. It lives in the regulation at 26 CFR §1.1298-1(c)(2), not in the exceptions section of the instructions that is often cited for it, and it relieves only the ownership-reporting requirement under section 1298(f). It applies where the aggregate value of PFIC stock is $25,000 or less for a single filer, $50,000 for a married couple filing jointly, or $5,000 for indirectly held section 1291 stock — and only where there is no excess distribution, no gain, and no qualified electing fund inclusion. A holder who sells files regardless of size.
Two elections can displace the default regime, and both depend on something outside the holder’s control. A qualified electing fund election under section 1295 requires the shareholder to receive and reflect a PFIC Annual Information Statement from the fund itself, setting out the shareholder’s pro rata share of ordinary earnings and net capital gain and granting access to the fund’s books or an approved alternative. A mark-to-market election under section 1296 requires the stock to be marketable — regularly traded on an SEC-registered national securities exchange or a market the Secretary has determined has adequate rules. A non-U.S. fund manager has no obligation to produce a QEF statement, which is why the election most often quoted as the fix is usually unavailable in practice.
What is specific to Americans abroad
The squeeze comes from both directions at once, and only Americans experience both.
Under the PRIIPs Regulation, Regulation (EU) No 1286/2014, a manufacturer must draw up a Key Information Document before a packaged retail investment product is made available to retail investors, and whoever distributes or sells it must provide that document in good time. The obligation has applied since 1 January 2018, the date set by the amending Regulation (EU) 2016/2340. A U.S. fund manager is not bound by an EU regulation and generally produces no KID.
France’s securities regulator, the Autorité des marchés financiers, has stated the consequence directly in an ombudsman case: since 2018 it has no longer been possible for the originator of a U.S. ETF to market it in the European Economic Area for lack of a KID, because the PRIIPs Regulation is not binding on U.S. investment management companies. The same decision draws a distinction worth keeping: the KID requirement bites on making a product available, and the AMF found it inappropriate for an intermediary to block the sale of a position held before 2018.
The regime therefore closes on new purchases, not on existing holdings. The route that remains open under the instruments themselves runs through client classification: the KID obligation is triggered for retail investors, and PRIIPs Article 4(6) defines a retail investor by reference to the MiFID II retail client. An investor who is classified as an elective professional under MiFID II Annex II — meeting at least two of three tests, including a portfolio exceeding €500,000 — falls outside that trigger. Classification is at the firm’s discretion, applies firm by firm, and forfeits retail protections.
One further note on timing. The EU’s Retail Investment Strategy, which amends PRIIPs among other instruments, reached provisional agreement between the Council and Parliament on 18 December 2025 and was classified as close to adoption as at May 2026, with plenary confirmation indicated for September 2026. Nothing published about the package suggests it opens EU retail access to U.S.-domiciled funds.
Why the sequence matters more than the diagnosis
A holder who already owns a foreign fund faces a genuine ordering problem rather than a single decision. Disposal is itself the event that triggers the full excess-distribution computation; the elections that would avoid it depend on information the fund may never supply; and the timing of a disposition determines which years’ top rates and how much section 6621 interest attach. Which of those constraints binds depends on facts — what is held, in what wrapper, since when, and what the fund reports — that cannot be determined from the outside.

Common questions
- Is my whole gain on a European index fund taxed at the highest rate plus interest?
- No. The highest-rate-plus-interest treatment reaches only the slices allocated to prior years in which the company was a PFIC. The current-year slice and any pre-PFIC period are simply included in ordinary income without an interest charge. The rate applied is the top rate in effect for each of those prior years — 39.6% for 2013 through 2017 — not the 37% top individual rate for 2026.
- Do I still have to file Form 8621 if my foreign fund is only worth a few thousand euros?
- The de minimis exception at 26 CFR §1.1298-1(c)(2) relieves only the ownership-reporting requirement under section 1298(f). It applies where the aggregate value of PFIC stock is $25,000 or less for a single filer, $50,000 for a married couple filing jointly, or $5,000 for indirectly held section 1291 stock — and only where there is no excess distribution, no gain and no qualified electing fund inclusion.
- Why can’t I just make a QEF election and avoid the PFIC rules?
- A qualified electing fund election under section 1295 requires the shareholder to receive and reflect a PFIC Annual Information Statement from the fund itself, setting out the pro rata share of ordinary earnings and net capital gain and granting access to the fund’s books or an approved alternative. A non-U.S. fund manager has no obligation to produce one, which is why the election most often quoted as the fix is usually unavailable.
- Can I keep the US ETFs I already own after I move to Europe?
- The PRIIPs regime closes on new purchases, not on existing holdings. France’s Autorité des marchés financiers has stated that since 2018 a U.S. ETF originator can no longer market in the European Economic Area for lack of a Key Information Document, because PRIIPs is not binding on U.S. investment management companies — while finding it inappropriate for an intermediary to block the sale of a position held before 2018.
- How much work is Form 8621 for a single foreign fund?
- A separate Form 8621 is required for each PFIC held, directly or indirectly, each year. The IRS publishes its own burden estimate for that form: roughly 17 hours of recordkeeping, 11 hours learning the law and the form, and 21 hours preparing and sending it — close to 49 hours in total, per fund, per year.
- Does the small-value exception still apply in the year I sell my foreign fund?
- Selling removes it. The de minimis exception applies only where there is no excess distribution, no gain and no qualified electing fund inclusion, so a holder who sells files regardless of size. It also lives in the regulation at 26 CFR §1.1298-1(c)(2) rather than in the exceptions section of the instructions often cited for it.
- If I sell a foreign fund, is the entire gain treated as an excess distribution?
- Yes. Section 1291(a)(2) applies the excess-distribution rules to gain on a disposition, and the Form 8621 instructions state that the entire gain on disposing of a section 1291 fund is treated as an excess distribution — with none of the 125%-of-the-prior-three-years cushion that applies to ordinary distributions.
- Can I make a mark-to-market election instead of a QEF election?
- A mark-to-market election under section 1296 requires the stock to be marketable — regularly traded on an SEC-registered national securities exchange, or on a market the Secretary has determined has adequate rules. That turns on the fund and the market it trades on rather than on the holder, which is what puts many ordinary European funds outside it.
- Why will my European broker not let me buy a US ETF?
- Under the PRIIPs Regulation, Regulation (EU) No 1286/2014, a manufacturer must draw up a Key Information Document before a packaged retail investment product is made available to retail investors, and it must be provided in good time. The obligation has applied since 1 January 2018. A U.S. fund manager is not bound by an EU regulation and generally produces no KID.
- Is there any way for an American in Europe to buy US-domiciled funds at all?
- The route that remains open runs through client classification. The KID obligation is triggered for retail investors, and PRIIPs Article 4(6) defines a retail investor by reference to the MiFID II retail client. An investor classified as an elective professional under MiFID II Annex II falls outside that trigger, and forfeits retail protections.
- Will the EU Retail Investment Strategy open US funds back up to Americans in Europe?
- Nothing published about the package suggests it opens EU retail access to U.S.-domiciled funds. The Retail Investment Strategy, which amends PRIIPs among other instruments, reached provisional agreement between the Council and Parliament on 18 December 2025 and was classified as close to adoption as at May 2026.
