The PFIC trap, explained

A PFIC — Passive Foreign Investment Company — is the worst-taxed asset class an American can own. The tax regime exists to discourage U.S. taxpayers from sheltering investment income in foreign mutual funds, and it does so by making the tax treatment so punitive that nobody who understands it would willingly hold one.

The catch: most expats holding PFICs don't know it. They opened a perfectly normal brokerage account at their local bank, bought a perfectly normal mutual fund or ETF, and don't realize that their Vanguard equivalent in Germany or Korea is a PFIC under U.S. law.

This article explains what a PFIC is, why it's so badly taxed, what your three options for handling one are, and the only sane long-term answer.

What makes something a PFIC

A foreign corporation is a PFIC for the year if either:

1. Income test: 75% or more of its gross income is passive (interest, dividends, capital gains), or
2. Asset test: 50% or more of its assets produce passive income.

Almost every foreign mutual fund and ETF passes both tests by design — that's literally what an investment fund is. So any non-U.S. pooled investment vehicle is, with rare exceptions, a PFIC.

Examples of PFICs:

• A UCITS ETF held at a European broker (iShares MSCI World listed in Ireland, etc.)
• A Korean mutual fund (펀드) bought through a Korean securities account
• A Japanese 投資信託 (toushin shintaku)
• A UK unit trust or OEIC
• A Canadian mutual fund (held outside an RRSP or TFSA — see treaty notes)
• Most foreign closed-end funds
• A foreign holding company with passive assets

What is not a PFIC:

• Direct holdings of foreign individual stocks (Toyota shares, not a fund holding Toyota)
• A U.S.-domiciled mutual fund or ETF (e.g., a Vanguard fund bought at Schwab) — even if it holds foreign stocks
• Active foreign operating businesses

Why the tax treatment is so bad

If you don't make a special election (more on those below), PFIC gains and "excess distributions" are taxed under the Section 1291 "excess distribution" regime. Here's what that means:

1. Gains are taxed at the highest ordinary rate. Long-term capital gains treatment does not apply. Gains on PFIC sales are taxed at your top ordinary marginal rate (potentially 37%).
2. Gains are spread over your holding period. The IRS treats a PFIC sale as if the gain accrued evenly over the years you held it. Each prior year is taxed at that year's highest ordinary rate.
3. Interest is charged on the "deferred" tax. Because the IRS treats each year's slice of the gain as if it should have been taxed back then, you owe interest from each prior tax year's filing deadline to today.
4. No basis step-up at death. Unlike most U.S. assets, your heirs do not inherit a stepped-up cost basis.
5. Reporting requires Form 8621 — one per PFIC, per year. Even a $200 holding in a single foreign ETF triggers a full Form 8621.

A 15-year buy-and-hold position in a foreign mutual fund that doubled can produce an effective tax rate north of 50% when interest and penalties are added in.

The three elections (your escape hatches)

If you find yourself holding a PFIC, you have three regimes to choose from:

1. The default: Section 1291 (excess distribution)

What was just described. You do nothing special. On sale, the gain is taxed under the punitive method above.

This is what 90% of accidental PFIC owners face when they realize the problem mid-stream — because the better elections must generally be made in the first year you own the PFIC.

2. QEF election — Qualified Electing Fund

If the PFIC provides an annual PFIC Annual Information Statement (PFIC AIS), you can elect to treat it like a U.S.-style pass-through fund. Each year you pick up your share of the fund's ordinary income and net long-term capital gains as if you held the underlying assets directly. The character is preserved — capital gains stay capital gains.

QEF is the best election when available. The catch: almost no foreign mutual funds provide a PFIC AIS. They have no obligation to, no incentive to, and producing one would require U.S. accounting that they don't do. A small number of funds marketed to expats (some Cayman-domiciled hedge funds, some specifically expat-targeted vehicles) provide AISs. Most do not.

If your fund does provide a PFIC AIS, make the QEF election in year one. You generally can't make it retroactively to a prior holding period without a "purging" election that resets your basis at fair market value and triggers the 1291 tax on the deemed sale.

3. Mark-to-market election

If the PFIC is marketable — regularly traded on a qualified exchange — you can elect mark-to-market treatment. Each year, you pick up unrealized gain (or loss, limited to prior gain) as ordinary income. There's no capital gains treatment, no QEF complexity, and no AIS requirement.

This is the most practical election for tradeable PFICs (e.g., listed UCITS ETFs). You pay tax on phantom income every year, but you escape the 1291 regime.

Like QEF, the election generally must be made for the first year you own the PFIC. A late election is possible with a purging mark-to-market deemed sale, taxed under 1291 — bad but bounded.

The reporting (Form 8621)

You must file Form 8621 for each PFIC you own, each year. The filing requirement applies if any of the following:

• You received a distribution from the PFIC.
• You sold or disposed of any shares.
• You're making or maintaining a QEF or mark-to-market election.
• The aggregate value of all your PFICs exceeded $25,000 ($50,000 MFJ) at any point in the year — even with no transactions.

The de minimis exception is the only relief: PFICs under $25,000 aggregate with no distributions or sales don't require Form 8621 (but they still must be reported on FBAR and possibly 8938).

Filing one Form 8621 is annoying. Filing twelve of them for twelve different funds in your foreign brokerage account is a multi-hour exercise that most tax software handles badly. Expat-focused preparers charge per-PFIC fees of $150–$400 because of this.

Treaty exceptions and special cases

A few national plans get treaty relief:

• Canadian RRSP / RRIF: U.S.-Canada treaty defers U.S. tax until distribution. PFICs inside an RRSP are generally not subject to the PFIC regime (subject to specific elections).
• UK ISAs: no treaty relief. PFICs inside a UK ISA still face the full PFIC regime — and the tax-free UK status doesn't carry over to the U.S.
• Australian Superannuation: PFIC rules can apply to fund holdings inside super; treatment is contested and unclear.
• Most European tax-advantaged accounts (German Riester, French PEA, Spanish ISA equivalents): no treaty relief from PFIC rules.

Don't assume a foreign tax-advantaged account is U.S. tax-advantaged.

The "sell now" question

If you discover mid-stream that you own PFICs you didn't make an election on:

1. Don't sell impulsively. The 1291 tax depends on how long you've held them. A long-held PFIC sold today could be a six-figure tax bill in a year you had no other gains to plan around.
2. Run the 1291 math first. Some PFIC sales are surprisingly small in tax (short holding period, modest gain). Others are devastating.
3. Consider timing. Selling in a year with lower other income (sabbatical, between jobs, partial-year U.S. residency) may reduce the highest marginal rate applied to each year's slice.
4. Talk to a credentialed pro before you click sell. This is the single tax decision where DIY most reliably ruins lives.

What about new PFIC purchases

Stop. Open a U.S. brokerage account that accepts your foreign address. Schwab International, Interactive Brokers, and a few others do this. Buy U.S.-domiciled ETFs (VTI, VOO, BND, etc.) — they are not PFICs because they are U.S. corporations.

If your foreign country restricts U.S. residents from holding U.S. ETFs (some EU PRIIPs rules effectively block U.S.-domiciled funds for EU retail investors), the workaround is to maintain "professional investor" status, hold individual stocks rather than funds, or use a U.S. brokerage that's not affected by the EU rules.

How PFICs interact with FBAR and FATCA

A PFIC held through a foreign brokerage account is reported on:

• FBAR (FinCEN 114): the account is a foreign financial account.
• Form 8938 (FATCA): the PFIC is a foreign financial asset.
• Form 8621: the PFIC itself.

Three different forms for the same fund. Welcome to expat tax.
