Few acronyms cause as much anxiety for a US person living in Europe as PFIC. You open a local investment account, buy a sensible low-cost index fund, and later discover you may have walked into one of the most punitive corners of the US tax code. The fear is understandable. The reassuring part is that PFIC exposure is largely structural, which means it is also largely avoidable once you understand where the rules reach and, just as importantly, where they do not.
This article explains what a PFIC is, why ordinary European funds fall into the trap, and the structural places the rules do not apply at all.
Not sure if your European funds are PFICs?
Cameron James USA helps US persons in Europe keep their growth assets in PFIC-safe wrappers, on a fee-based plan with no products sold on commission. Our advisers hold individual SEC authorization.
What Is a PFIC?
PFIC stands for Passive Foreign Investment Company. From the perspective of the US Internal Revenue Service (IRS), foreign simply means non-US. A PFIC is, broadly, any pooled investment vehicle domiciled outside the United States that earns most of its income from passive sources such as dividends, interest and capital gains. Each PFIC is generally reported on its own IRS Form 8621.
That definition captures almost every fund a European investor would naturally buy:
- EU domiciled SICAVs, FCPs and other open-ended pooled funds
- UCITS funds, including Irish and Luxembourg domiciled index funds and ETFs
- Local closed-ended and listed investment funds
In other words, the standard building blocks of a sensible European portfolio are, in the eyes of the IRS, PFICs.
Why PFICs Are So Punitive
The default PFIC regime is designed to remove any benefit from deferring income in a non-US fund, and it does so aggressively.
Under the default regime, the Section 1291 excess distribution rules, gains and certain distributions are taxed at the highest ordinary income rates rather than the lower long-term capital gains rates, and an interest charge is layered on top to claw back the perceived benefit of deferral. On top of the tax cost, each PFIC must generally be reported on a separate IRS Form 8621 every year, which is time consuming and, when prepared professionally, expensive.
There are elections that can soften this, the Qualified Electing Fund election and the mark-to-market election, but they depend on the fund providing the right information, and most non-US funds simply do not produce a PFIC annual information statement. For the great majority of US persons, the practical answer is to avoid holding PFICs in the first place.
The Catch-22 for US Persons in Europe
Here is where it becomes frustrating. The obvious fix would be to buy US domiciled funds instead, because a US domiciled fund is not a PFIC. But a separate set of EU rules, the PRIIPs Key Information Document requirements, makes it very difficult for a European retail investor to buy US domiciled funds in the first place.
So the US person in Europe is caught between two regimes:
- Buy a European fund and you have a PFIC problem.
- Try to buy a US fund and the EU Key Information Document rules block you.
We cover how platforms respond to this in our guide to PFIC restrictions and access to US listed funds from Europe. The point for now is that this catch-22 has a structural escape hatch, and it is one of the most important things a US person in Europe can understand.
Where PFIC Rules Do Not Apply: Inside a Pension
PFIC rules do not apply to investments held inside a pension. This is the single most important point in this article.
US retirement accounts are PFIC exempt wherever you live, because a US pension is not a foreign pooled fund in the eyes of the IRS. The following accounts are recognized as pensions and shield the investments held inside them:
- US 401(k) plans and other US employer plans
- US Traditional Individual Retirement Accounts (IRAs)
- US Roth IRAs
- Treaty-recognized local pensions, where the relevant US tax treaty gives them pension status
Because these wrappers are treated as pensions, PFIC rules do not apply to the investments held inside them. Inside an IRA or a rolled-over 401(k), a US person can hold diversified, pooled funds without creating PFIC exposure. The position on a local European pension is less uniform, because each member state has its own tax treaty with the US, so whether a given local pension is recognized, and how it is taxed, has to be checked country by country.
This changes the entire planning picture. The asset that would be radioactive in a taxable account is perfectly acceptable inside the pension wrapper. It is why, for most US persons in Europe, pensions sit right at the top of the investment priority list.
If you have an old US employer plan, our guide to 401(k) to IRA rollovers under SEC-regulated advice explains how to consolidate it without triggering an unnecessary tax event.
Where PFIC Rules Still Bite
Outside the pension wrapper, the PFIC rules are very much alive. The accounts to watch are set out below.
| Account | PFIC shield? | What this means in practice |
|---|---|---|
| US IRA / 401(k) / Roth IRA | Yes | Pooled funds are fine inside the wrapper. |
| Treaty-recognized local pension | Sometimes | Depends on the specific US-country tax treaty. |
| Local taxable brokerage account | No | PFIC rules apply in full to non-US pooled funds such as UCITS, SICAVs and FCPs. |
| Assurance Vie, PEA and similar local wrappers | No | Not recognized by the IRS, so no PFIC shield, and foreign trust reporting may also arise. |
| US HSA | No | Not recognized by most European tax authorities; PFIC applies to any non-US funds held in it. |
| US 529 plan | No | Treated as a taxable account in most European countries; PFIC applies to non-US funds. |
These local wrappers are the ones that catch people out. A French Assurance Vie or PEA, and their equivalents elsewhere in Europe, look tax efficient locally, and for local purposes they often are, but the IRS does not recognize them, so they offer no PFIC shield. That is why a US person in Europe generally cannot hold pooled funds in these wrappers and is pushed toward individual stocks or US domiciled funds instead.
A Note on Form 3520 and Foreign Grantor Trusts
Separate from PFIC, there is a long-running question about whether certain non-US arrangements should be reported to the IRS as foreign grantor trusts on Forms 3520 and 3520-A. A French Assurance Vie is a common example, and the position on some local pensions is genuinely unsettled, with several schools of thought. It does not change the PFIC position, because PFIC still does not apply inside a recognized pension, but it is something to take advice on, and we treat it as a separate topic.
A Note From Jonathan Laws
How Cameron James USA Helps
Getting this right is mostly about asset location: making sure your growth assets sit in the wrappers where PFIC cannot reach them, and that you are not unintentionally holding PFICs in a local brokerage account or a wrapper like an Assurance Vie. Where US listed, non-PFIC funds are appropriate, we also help with the access problem covered in our guide to PFIC restrictions and US listed funds from Europe.
About Cameron James USA and how we are regulated
Cameron James USA advisers hold individual SEC authorization in the US and hold individual EU and EEA authorizations where applicable. This adviser-level authorization on both sides is what allows us to advise on your US accounts and your European accounts within a single coordinated plan, rather than leaving you to stitch together US-only and local-only advice that does not join up.
In practice, that means we can:
- Structure your portfolio so equity and other growth assets sit inside PFIC-safe pension wrappers
- Build globally diversified portfolios using US listed, non-PFIC ETFs where appropriate
- Coordinate your US and local tax reporting so the two systems work together rather than against each other
Get your assets in the right place
PFIC is a structural problem, which means it has a structural answer. We make sure your growth assets sit inside PFIC-safe wrappers and that your US and local reporting work together rather than against each other. Fee-based, with no products sold on commission.

Frequently Asked Questions
Do PFIC rules apply to a US IRA?
No. A US IRA is a recognized pension, and PFIC rules do not apply to investments held inside it. The same is true of 401(k) plans and Roth IRAs, wherever in Europe you live.
Do PFIC rules apply to a French Assurance Vie or PEA?
Yes. These wrappers are tax efficient for local purposes but are not recognized by the IRS, so they provide no PFIC protection. Holding pooled European funds inside them creates PFIC exposure, and an Assurance Vie can raise foreign trust reporting questions on top.
Is a US domiciled ETF a PFIC?
No. PFIC rules apply only to funds domiciled outside the US, so a US domiciled ETF is not a PFIC. The challenge with US ETFs is access through European platforms, not their PFIC status.
I hold a UCITS index fund or ETF. Is that a PFIC?
Almost certainly yes. EU domiciled funds, including UCITS index funds, ETFs and SICAVs, are generally PFICs for US tax purposes.
What is Form 8621?
It is the IRS form used to report a holding in a PFIC. A separate form is generally required for each PFIC, each year, which is one of the reasons holding PFICs is so burdensome.

“Most of the PFIC worry I see is retrospective. A client has already bought a local index fund, often after their local bank suggested it, and is now anxious about what it means on their US return. That anxiety is fair, but the fix is almost always calmer than the fear. PFIC is a structural problem, and structural problems have structural answers.
The single move that solves most of it is asset location. Keep your growth assets inside the pension wrappers, where PFIC cannot reach them, and be deliberate about what you hold in a local brokerage account or a wrapper like an Assurance Vie. Get the location right and the rest of the PFIC question becomes much smaller than it first appears.”
