US tax on foreign ETFs
How a non-US ETF is taxed on a US return, why it is treated worse than the US-domiciled equivalent, and what the reporting actually involves.

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.
| US-domiciled ETF | Foreign (non-US) ETF | |
|---|---|---|
| PFIC? | No | Generally yes |
| Gain on sale | Capital gain; long-term rates if held over a year | Default §1291: ordinary rates + interest charge |
| PFIC form | No Form 8621 | A separate Form 8621 can apply when a reporting trigger is present |
| Qualified dividends | Possible | Not available under §1291 |
| Losses | Ordinary capital-loss rules | Restricted under the PFIC regime |
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.
