US tax on foreign ETFs

You opened a brokerage account where you live, bought a broad index fund because that is the sensible thing to do, and have since read something alarming about Americans and European ETFs. The question underneath is usually: did I break something, and how badly?

The short answer: you have not done anything wrong, and nothing here is a reason to panic-sell. What you have probably done is create a reporting and tax-treatment problem — one that is well-defined, and that behaves differently from how a US investor would expect a long-held index fund to behave. This page explains what actually decides it, what it is likely to cost to deal with, and which parts are worth paying for.

The mechanics: a US citizen or green-card holder generally reports worldwide income, so a foreign ETF's distributions, elections and dispositions need U.S. analysis regardless of where the account sits or which currency it uses. Separate annual PFIC reporting can also apply, subject to the Form 8621 filing triggers and exceptions.

The core difference: PFIC treatment

A non-US ETF is a pooled foreign fund, which generally makes it a PFIC. That is not just an extra form. It changes the tax regime: instead of ordinary capital-gain treatment, the default §1291 rules spread your gain back across the holding period, tax each year's slice at that year's highest ordinary rate, and add a compounded interest charge for the delay. Long holding periods make it worse, not better — the opposite of how US investors expect a buy-and-hold position to behave.

What decides it — and four things that do not

PFIC status turns on the fund's own structure and where the fund itself is established. Almost every near-miss on this question comes from using one of these four as a proxy for that instead.

"But I have never sold anything"

This is the most common reason people conclude nothing applies to them, and it is worth separating into three claims, because only one of them is true.

• Not selling defers most of the §1291 tax. True. The excess-distribution machinery mainly fires on distributions and on disposal.
• Not selling means no reporting. Not true. Form 8621 has its own filing triggers that do not require a sale, and the account holding the fund counts toward the FBAR and Form 8938 tests regardless.
• Not selling means the problem is not growing. Not true, and this is the one that costs. The §1291 interest charge is a function of how long you have held the position — the deferred tax accrues an interest charge across the holding period, so an untouched fund quietly becomes more expensive to unwind each year.

Accumulating funds do not solve it

An accumulating share class does not avoid PFIC analysis. PFIC status turns on the foreign corporation's income and assets, not whether the fund distributes cash. The U.S. timing depends on the applicable PFIC method: QEF and mark-to-market have annual inclusions, while §1291 focuses on distributions and dispositions plus any annual information-report requirement.

Elections that improve the outcome

• QEF (§1295) — includes the shareholder's pro-rata ordinary earnings and net capital gain, but requires a valid PFIC Annual Information Statement from the fund.
• Mark-to-market (§1296) — recognizes supported annual value changes as ordinary income or limited ordinary loss, but only when the stock meets the statutory marketability requirements.
• §1291 (default) — what you get by doing nothing, and the reason PFIC returns are worth taking seriously.

The reporting around the fund

Separately from PFIC treatment, the account holding the ETF is a foreign financial account. It counts toward the FBAR aggregate and toward the Form 8938 thresholds. These are account-level obligations that apply whether or not anything inside the account is a PFIC — a distinction worth keeping straight, because they are filed in different places under different rules.

What about my local tax-free account?

A wrapper that is tax-free where you live is not tax-free for U.S. purposes. Local exemption is granted by local law and the United States does not adopt it — the treatment of what is inside the wrapper generally still applies, and some wrappers add a second problem by being trusts in U.S. terms.

These differ enough that one sentence would be wrong for most readers, so each is handled where it belongs: the French PEA and assurance-vie, the UK ISA, the Canadian TFSA and RRSP, the German ETF-Sparplan, and the Swiss pillar 3a. Find yours before assuming it behaves like any of the others.

Potential tax and preparation fees are different numbers

People conflate these constantly, and it makes the whole subject sound more frightening than it is. They move independently:

• The tax depends on your holdings, how long you have held them, what they distributed and which elections apply. It can be zero. Under §1291 on a long-held position it can be substantial. Nobody can quote it from a page — it needs your actual numbers.
• The preparation fee depends on how many funds need a form. Firms that price per Form 8621 are the reason a modest portfolio can produce an alarming quote: at typical per-form rates, roughly 3 funds is where per-form pricing passes our flat $499 for up to 25 forms.
• A handoff to your own accountant is a third number again — $199 for the analysis and worksheets if you already have someone who files for you.

What to gather before anyone can answer properly

• Each fund's identifier and domicile — the ISIN and the factsheet, which states where the fund is established.
• When you first bought each holding. The §1291 calculation allocates across your whole holding period, so the purchase date is not optional detail.
• Every purchase, sale and distribution, with dates and amounts in the currency they occurred in.
• Any election already made on a fund in a past year. A QEF or mark-to-market election that already exists changes everything downstream.
• The account's peak balance each year, which is a separate test from anything about the funds themselves.

What to ask your local adviser

Your bank or adviser is not required to know U.S. tax law and mostly does not. That is not a criticism — it is a reason to ask precise questions rather than "is this OK for an American?", which invites a reassuring answer nobody can back.

• Where is this fund domiciled? (Not where it is listed, not what it holds.)
• Is there a US-domiciled equivalent available on this platform for a U.S. person?
• Does the fund publish a PFIC Annual Information Statement? Without one, a QEF election is not available.
• Can you give me a full transaction history including distributions, from the beginning?
• Are there exit costs, lock-ins or local tax consequences if a position is changed?
