Do you actually need Form 8621?
If you are a U.S. taxpayer holding a non-U.S. ETF, mutual fund or similar fund, it is probably a PFIC — and Form 8621 is generally due once per fund, per year. But not always. A sale, a distribution or an election generally means it is needed; small holdings, a U.S. retirement account or a treaty-recognised pension can remove it.
This assessment checks your foreign funds, ETFs, pensions and similar holdings one at a time, and tells you which may be PFICs, whether Form 8621 appears relevant for your year, which exceptions may apply and what is still missing — before you pay anyone to prepare anything.

One investment at a time: where it is based, what it is, how you hold it and what happened in the year. Most questions have a “Not sure” answer, and that is useful too. About three minutes per investment.
What the assessment looks at
The facts that decide Form 8621 — and only those. Each one is asked because it can change the answer.
- Where it is based
- A fund's legal home decides whether it is foreign at all. A U.S.-domiciled ETF is never a PFIC.
- What it is
- A pooled fund, an investment company, a pension, an insurance policy or an ordinary company — each is read differently.
- How you hold it
- Directly, jointly, in an IRA, in a foreign pension, through a company or a trust: the wrapper can change who reports, or whether anyone does.
- When you held it
- The year bought and whether it was sold — the holding period drives both the history and any §1291 calculation.
- Roughly what it was worth
- In ranges built around the exception thresholds, never an exact figure.
- What happened in the year
- Distributions and sales are what turn an annual report into a tax computation.
- How it was treated before
- Earlier Forms 8621, QEF or mark-to-market elections, and any professional view.
- Your U.S. status
- Form 8621 is filed by U.S. persons; residence decides the treaty. Taken from your Tax Map when you have one.
Who it is for
U.S. citizens, green card holders and other U.S. taxpayers — at home or abroad — who hold investments outside the U.S.: an ETF bought through a European broker, a fund in an ISA or a PEA, a Swiss or Canadian mutual fund, a pension with funds inside it, or a portfolio of several. One holding or thirty.
What it does not do
It does not decide that a fund is a PFIC, apply an exception, calculate tax or choose between §1291, QEF and mark-to-market. It does not replace a practitioner where judgement is needed — it prepares the facts so that a practitioner, ours or yours, does not have to ask them again.
Questions people ask before filing
Do I need to file Form 8621?
If you are a U.S. person — a citizen, a green card holder or a U.S. tax resident — and you hold shares of a PFIC, the rule is generally one Form 8621 per PFIC, per year, unless an exception applies. In practice almost every non-U.S. ETF and mutual fund, UCITS funds included, is a PFIC. Whether the form is actually required for a given year depends on what happened that year (a sale, a distribution, an election) and on the exceptions.
Which exceptions can remove Form 8621?
The main ones: the small-holdings exception (aggregate PFIC value of $25,000 or less on the last day of the year ($50,000 MFJ), and only for funds with no QEF or mark-to-market election and no excess distribution or disposition gain in the year); shares held through an IRA, a 403(b) or 457(b) plan, a 529 or 530 account or another U.S. tax-exempt account; shares held through a foreign pension that a tax treaty treats as taxable only on payout; and, for a 10% U.S. shareholder, the controlled-foreign-corporation overlap rule. Each has conditions that need confirming before it is relied on.
Is a U.S.-domiciled ETF a PFIC?
No. A fund organised in the United States is a domestic entity, and the PFIC rules apply only to foreign corporations — wherever you bought the fund or live. That is why many Americans abroad hold U.S.-domiciled ETFs, where their broker allows it.
Are UCITS ETFs PFICs?
A UCITS ETF is a pooled fund organised outside the U.S., usually in Ireland or Luxembourg, so it is the shape the PFIC rules describe and in practice almost always meets the PFIC income or asset test. The assessment treats it as a potential PFIC — a screen, which the fund's legal form and its own figures confirm — and then reads whether the form is actually needed for your year.
I have never filed Form 8621. What now?
Many people only learn about PFICs years after buying a fund. The assessment marks the holding for historical review rather than drawing conclusions: whether earlier years needed the form depends on each year's facts and exceptions, and the order in which the years are put right matters. A professional review settles it before anything is filed.
Does the assessment decide for me?
No. It separates what follows from your facts (a U.S. fund is not a PFIC) from what is a strong screen (a non-U.S. ETF is a potential PFIC) and from what needs a professional's judgement (a pension, an insurance policy, a fund held through a company or trust). Where an exception may be relevant it says so and lists what to confirm — it never applies one for you.
What happens to my answers?
They are saved to your assessment so you can come back to it, and to nothing else. You can name a fund, but you are never asked for an account number or an exact value — values are ranges. Analytics receives which step you reached and bucketed counts, never an answer or a fund name. An email is only asked for after the result, if you want a link or a review.
