The PFIC Trap for Americans in Europe in 2026
The wrapper’s country of organisation decides the tax treatment, not what the fund holds — and European rules block most Americans in Europe from buying the wrapper the United States taxes normally
A European-domiciled UCITS ETF is almost always a PFIC for a US citizen, because Internal Revenue Code section 1297 applies to foreign corporations and a Dublin- or Luxembourg-domiciled fund is one. A US-domiciled ETF holding identical shares is not. The wrapper’s country of organisation decides the tax treatment, not what the fund holds.
An American who moves to Lisbon or Valencia and opens a European brokerage account meets a problem with no clean answer. The funds the account will sell are taxed punitively by the United States. The funds the United States taxes normally are the ones European rules will not let a retail investor buy. The two systems do not conflict by accident — each was built without reference to the other — but the person standing between them is an American in Europe with money to invest.
This page sets out what is on each side of that wall, and the three routes through it that actually exist.
| Wrapper | A PFIC? | Form 8621 required? | Can an EU retail investor buy it? |
|---|---|---|---|
| US-domiciled ETF or mutual fund | No — a domestic corporation under section 7701(a)(4) | No | Generally no — no PRIIPs key information document exists, so the broker blocks the trade |
| UCITS ETF (Ireland, Luxembourg) | Yes — a foreign corporation failing both the income and asset tests | Yes, subject to the $25,000 aggregate exception | Yes — a key information document has been mandatory since 1 January 2023 |
| Foreign mutual fund, SICAV or OEIC | Yes — same analysis | Yes, same exception structure | Usually, where a key information document exists |
| Individual shares, US or European | No — an operating company fails neither test | No | Yes — a share is not a packaged product, so no document is required |
| US mutual fund bought before the move | No — a domestic corporation | No | Existing holdings can be kept; new purchases are commonly blocked by the broker |
Why domicile is the whole question
Section 1297 defines a passive foreign investment company by two tests, and failing either one is enough. Under the income test, 75 per cent or more of the corporation’s gross income for the year is passive. Under the asset test, at least 50 per cent of its assets on average produce passive income or are held for that purpose. A fund fails both by design: its income is dividends and interest, and its assets are securities.
The word that does the work is foreign. Section 1297 reaches only a foreign corporation, and section 7701(a)(4) defines a domestic corporation as one created or organised in the United States or under the law of any State. A Delaware-organised ETF is therefore outside the regime no matter how passive it is. A Dublin-organised ETF is inside it no matter what it holds. An S&P 500 tracker domiciled in Ireland is a PFIC; an emerging-markets fund domiciled in Massachusetts is not.
What the default regime does
Left alone, a PFIC is taxed under section 1291, and the mechanics are unusual enough to be worth stating precisely. An excess distribution — the part of a year’s distributions exceeding 125 per cent of the average of the previous three years — is allocated rateably across every day of the holding period. Each year’s slice is then taxed at the highest rate of tax in effect for that year, not at the investor’s own rate and not at capital gains rates. An interest charge is then added, computed under the section 6621 rates for underpayments of tax, as though the tax had been due in the year the income was allocated to.
The consequence runs against ordinary investing instinct. A long holding period makes the outcome worse rather than better, because it lengthens the allocation and lengthens the interest.
The two elections, and why they are harder than they look
The qualified electing fund election under section 1295 replaces that regime with something close to normal flow-through taxation. It has one obstacle. The election is valid only where the fund complies with the reporting requirements, which in practice means the fund issues a PFIC Annual Information Statement — a document, signed by the fund, setting out the shareholder’s pro rata share of ordinary earnings and net capital gain, the distributions received, and a statement that the fund will permit the shareholder to inspect and copy its books of account.
Nothing in United States law obliges an Irish fund to produce that statement, and nothing in European law does either. The escape route from section 1291 depends on the voluntary cooperation of a foreign entity that has no regulatory relationship with the shareholder at all. A minority of providers publish the statements; most do not.
The mark-to-market election under section 1296 needs no cooperation, but it is narrower than it sounds. It applies only to marketable stock, defined as stock regularly traded on a national securities exchange registered with the Securities and Exchange Commission, or on an exchange the Secretary has determined has adequate rules. Whether a particular European-listed share class clears that bar is a determination-and-facts question rather than a settled yes. Where it applies, gains are ordinary income each year on unrealised appreciation, and losses are deductible only against prior inclusions.
The paperwork, in the government’s own numbers
Form 8621 is filed per fund, per year. The exception most often cited is real but narrower than its reputation: Part I may be omitted where the aggregate value of all PFIC stock is $25,000 or less on the last day of the year — $50,000 on a joint return — and only where there is no excess distribution, no gain on disposition, and no qualified electing fund election in place. It is an aggregate test across every holding, not a per-fund allowance, and any one of those three events removes it.
The instructions to Form 8621 carry the Internal Revenue Service’s own burden estimate: recordkeeping 16 hours 58 minutes, learning about the law or the form 11 hours 24 minutes, and preparing and sending the form 20 hours 34 minutes. That is close to 49 hours per form, per fund, per year, by the government’s reckoning. Four European funds imply roughly 196 hours a year.
The wall on the European side
The reason the obvious answer — buy the American fund — usually fails is a different regulation entirely. Regulation (EU) No 1286/2014 requires that before a packaged retail investment product is made available to retail investors, the manufacturer draws up a key information document, and that anyone advising on or selling the product provides it before the investor is bound. United States fund issuers do not as a rule produce those documents, because they are not selling into Europe.
Interactive Brokers states the mechanism plainly on its own education site: issuers of US-listed ETFs do not as a rule create key information documents, so EEA and UK retail clients cannot purchase the product, and the firm is required to block trading in a packaged product where no document is available.
The transitional exemption that once spared UCITS funds ended on 31 December 2022 under Regulation (EU) 2021/2259, so a European fund now carries a key information document and an American one still does not. The European Commission has an ongoing revision of the regulation under way, so the boundary is not permanently fixed.
The three routes that exist
The first is individual shares. A share is not a packaged product, so no key information document is required, and an operating company is not a PFIC. It is the only wrapper that is clean on both sides. What it costs is diversification.
The second is elective professional status under MiFID II. A retail client may be reclassified where at least two of three criteria are met: transactions in significant size at an average frequency of ten per quarter over the previous four quarters; a financial instrument portfolio, including cash deposits, exceeding EUR 500,000; or at least a year working in the financial sector in a position requiring the relevant knowledge. The firm must assess expertise, warn in writing which protections are lost, and take a separate written acknowledgement from the client. Professional clients fall outside the key information document requirement.
The third is to accept the PFIC regime knowingly, hold European funds, and file Form 8621 — usually the position of someone whose European tax position dominates the arithmetic.
What a move does not do
Funds bought before leaving the United States are not retroactively affected. A US-domiciled fund remains a domestic corporation and never becomes a PFIC. What changes is the broker’s willingness to accept new purchases: Fidelity’s own document states that customers residing outside the United States have not been able to purchase shares of mutual funds since 1 August 2014, while existing holdings may be kept and dividends reinvested. Selling a long-held US fund in order to simplify can therefore realise a large capital gain for no tax reason at all.

Common questions
- Is every European ETF a PFIC?
- Almost every one. The test is the fund’s country of organisation, not its holdings. A fund organised in Ireland or Luxembourg is a foreign corporation, and a fund’s income is passive and its assets are securities, so it fails both the section 1297 tests. A fund organised in a US state is a domestic corporation and falls outside the regime entirely.
- Does a UCITS fund that only holds US shares avoid PFIC status?
- No. The holdings are irrelevant to the test. An Irish-domiciled fund tracking the S&P 500 is a foreign corporation whose income is dividends and whose assets are securities, so it meets both the income and asset tests. Domicile decides the question, which is why two funds with identical portfolios can be taxed completely differently.
- What does the default PFIC regime actually cost?
- Under section 1291 an excess distribution is spread rateably over the entire holding period, each year’s slice is taxed at the highest rate in effect for that year rather than the investor’s own rate, and an interest charge computed under section 6621 is added on top. Capital gains rates do not apply, and a longer holding period increases the charge.
- Can the qualified electing fund election fix it?
- Only where the fund cooperates. A section 1295 election is valid where the fund complies with the reporting requirements, which in practice means issuing a signed PFIC Annual Information Statement showing pro rata earnings and gain and undertaking to open its books. No US or EU law obliges a European fund to produce one, and most do not.
- What about the mark-to-market election?
- Section 1296 applies only to marketable stock — stock regularly traded on an SEC-registered national securities exchange, or on an exchange the Secretary has determined has adequate rules. Whether a given European-listed share class qualifies is fact-specific. Where it applies, unrealised gains are taxed annually as ordinary income and losses are deductible only against prior inclusions.
- Is there a threshold below which Form 8621 is not filed?
- There is a narrow one. Part I may be omitted where the aggregate value of all PFIC stock is $25,000 or less on the last day of the year, or $50,000 on a joint return. It is lost where there is an excess distribution, a gain on disposition, or a qualified electing fund election. It is an aggregate figure across all holdings, not a per-fund allowance.
- How long does Form 8621 take?
- The instructions carry the Internal Revenue Service’s own estimate: 16 hours 58 minutes recordkeeping, 11 hours 24 minutes learning about the law or the form, and 20 hours 34 minutes preparing and sending it. That is close to 49 hours for one form covering one fund for one year. The form is filed separately for each PFIC held.
- Why can an American in Portugal not simply buy a US-domiciled ETF?
- Because Regulation (EU) No 1286/2014 requires a key information document before a packaged retail product is made available to retail investors, and US issuers do not as a rule produce them. Interactive Brokers states on its own site that it is required to block trading in a packaged product where no such document is available.
- Do US shares bought before the move become PFICs?
- No. A fund organised in a US state remains a domestic corporation permanently, and nothing about moving abroad changes that. What commonly changes is the broker’s policy on new purchases. Fidelity’s own document confirms that existing holdings may be kept and dividends reinvested, while mutual fund purchases have been closed to customers abroad since 1 August 2014.
- What is elective professional status under MiFID II?
- A route by which a retail client is reclassified as professional, which removes the key information document requirement. At least two of three criteria must be met: ten significant transactions per quarter over four quarters, a portfolio including cash above EUR 500,000, or a year working in the financial sector in a relevant role. Investor protections are given up in exchange.
- Are individual shares treated differently?
- Yes, on both sides. An operating company is not a fund and normally fails neither the income nor the asset test, so it is not a PFIC and no Form 8621 arises. A share is also not a packaged retail product, so no key information document is required and European brokers do not block it. The trade-off is the loss of diversification.
