What Is a PFIC? A Practical Guide for American Expats
Learn how the PFIC income and asset tests work, why many foreign pooled investments require review, and how Form 8621 treatment can differ by fund and election.
What Is a PFIC? A Complete Guide for American Expats
If you are a U.S. person living abroad and own a foreign mutual fund, ETF, unit trust, or investment wrapper, ask whether the vehicle is a PFIC before you sell, transfer, or make an election. The classification depends on the legal entity, domicile, income and asset tests, and the relevant tax year. The rules can produce a less favorable result than ordinary capital-gain treatment, but “foreign fund” is not a complete calculation.
The Definition
PFIC stands for Passive Foreign Investment Company. It is defined in IRC Section 1297 as any foreign corporation meeting one of two tests:
- The Income Test: 75% or more of gross income is passive (dividends, interest, rents, royalties, capital gains).
- The Asset Test: 50% or more of assets produce passive income or are held for the production of passive income.
A foreign corporation only needs to meet one of these tests to be a PFIC. The tests are applied annually, so a corporation can be a PFIC in one year and not in another. For practical purposes, however, most foreign investment funds are PFICs every year.
Why PFICs Exist
The PFIC rules address potential deferral of U.S. tax through certain foreign investment vehicles. Their operation is technical: the default regime, QEF election, mark-to-market election, basis, holding period, distributions, and available annual information statement all affect the outcome. Avoid describing every PFIC as “toxic” or every election as available without reviewing the specific fund.
Real-World Examples
Foreign Mutual Funds
A British expat in London buys shares in a UK-domiciled equity fund listed on the London Stock Exchange. The fund pools investor money, buys stocks, and generates dividends and capital gains. Because 100% of the fund's income is passive and 100% of its assets are passive investments, it is a PFIC. The expat must file Form 8621 annually.
UCITS and OEICs
UCITS (Undertakings for Collective Investment in Transferable Securities) are the standard fund structure in the EU. OEICs (Open-Ended Investment Companies) are common in the UK. Both are pooled investment vehicles domiciled outside the US. Both are PFICs. Your local bank or financial advisor in Madrid, Paris, or Frankfurt will sell these as standard products. They are toxic for US taxpayers.
Foreign ETFs
A US expat in Japan buys a Nikkei-tracking ETF listed on the Tokyo Stock Exchange. The ETF is a Japanese corporation. Its income is passive. It is a PFIC. The same expat could have bought EWJ or VPL through a US broker — same exposure, no PFIC problem.
Unit Trusts and ISAs
UK unit trusts are classic PFICs. Individual Savings Accounts (ISAs) that hold unit trusts or OEICs do not shield the underlying PFIC status. The ISA wrapper may be tax-advantaged under UK law, but the US tax treatment ignores the wrapper and looks through to the underlying investments.
Insurance Wrappers
Offshore investment-linked insurance policies — common in jurisdictions like the Isle of Man, Guernsey, or Bermuda — often hold a portfolio of mutual funds inside the policy. The policy itself may or may not be a PFIC depending on its legal structure, but the underlying funds almost certainly are. These products are sold aggressively to expats by offshore advisors who rarely understand US tax consequences.
The Three Tax Regimes
Once you own a PFIC, one of three tax regimes applies:
1. Excess Distribution Regime (Default)
If you make no election, this is what happens when you receive a distribution or sell at a gain:
- The gain or excess distribution is allocated ratably over your entire holding period.
- Each year's portion is taxed at the highest ordinary income rate for that year.
- A non-deductible interest charge is imposed on the deferred tax, compounded daily.
- Losses are not recognized.
Example: You buy a PFIC for $50,000, hold it for 10 years, and sell for $150,000. The $100,000 gain is spread over 10 years. Each year's $10,000 is taxed at the highest ordinary rate ( historically 35–39.6%). Interest charges apply to the deferred tax for each year. Your effective federal tax rate on the gain can exceed 50%.
2. Qualified Electing Fund (QEF) Election
If the PFIC provides an Annual Information Statement, you can elect QEF treatment. This is the most favorable regime:
- You report your pro-rata share of the PFIC's ordinary income and net capital gain annually, even if not distributed.
- Gains on sale are taxed as capital gains, not ordinary income.
- No interest charge.
- Prior-year unreported income is not taxed on sale.
The problem: most foreign funds refuse to provide an Annual Information Statement. Without it, you cannot make a QEF election.
3. Mark-to-Market Election
If the PFIC is marketable stock (traded on a public exchange), you can elect mark-to-market:
- You recognize unrealized gains and losses annually as ordinary income.
- True capital gains and losses are recognized only on sale.
- No interest charge.
This is useful for publicly traded PFICs but still inferior to normal capital gains treatment because annual unrealized gains are ordinary income, not capital gains.
Why This Matters for Expats
The calculations can be severe
The excess-distribution regime can be materially less favorable than ordinary long-term capital-gain treatment because of allocation and interest rules. The actual result requires the fund's records and the taxpayer's holding history; a headline effective rate is not a substitute for a Form 8621 calculation.
Form 8621 Is Complex
Every PFIC requires a separate Form 8621. If you own 10 foreign funds, you file 10 Forms 8621. The form is 6–8 pages per PFIC and requires data most taxpayers do not have. The instructions are dense, and the calculations for excess distributions are genuinely difficult.
Financial Advisors Abroad Don't Understand PFICs
I have reviewed hundreds of expat portfolios. In maybe 5% of cases did the local advisor warn the client about PFICs. The other 95% were sold toxic products by well-meaning professionals who simply never learned US tax law. This is not their fault — but it is your problem.
Safe Alternatives
You do not need foreign funds to invest globally. Here is what works:
- US-listed ETFs and mutual funds with international exposure: VXUS, VTIAX, FTIHX, IXUS, VWO, VEA.
- Individual foreign stocks bought through a US broker: direct ownership of Toyota, Nestle, or Samsung is not a PFIC.
- US Treasury bonds and US corporate bonds held through a US broker.
- Direct real estate in the host country.
- Foreign bank deposits in CDs or savings accounts — interest is taxable but the account is not a PFIC.
The Form 8621 Filing Requirement
You must file Form 8621 if you:
- Receive a distribution from a PFIC.
- Recognize a gain on PFIC stock.
- Make a QEF or mark-to-market election.
- Own a PFIC that is also a CFC and you file Form 5471.
- Are a indirect shareholder of a PFIC through another PFIC (the look-through rules).
There is no de minimis exception. One share of one foreign fund triggers the form.
PFICs and the FEIE
The Foreign Earned Income Exclusion (FEIE) only applies to earned income — wages, salaries, self-employment income. PFIC income is passive investment income. It does not qualify for the FEIE. Even if you exclude $132,900 of salary under the FEIE, your PFIC distributions are fully taxable, often at the highest ordinary rates with interest charges.

Frequently Asked Questions
What makes an investment a PFIC?
A foreign corporation is a PFIC if it meets either the income test (75% or more of gross income is passive) or the asset test (50% or more of assets produce passive income). Many foreign-domiciled pooled investment vehicles require PFIC review, but domicile, legal structure, and the facts for the year matter. Do not classify an investment from its marketing name alone.
Are US-listed international ETFs PFICs?
No. US-listed ETFs like VXUS, VTIAX, or FTIHX are domiciled in the US. The PFIC rules apply to the domicile of the investment vehicle, not the nationality of the underlying stocks. A US-domiciled fund that holds Japanese or German equities is not a PFIC. This is why every expat should maintain a US brokerage account and avoid local foreign funds.
What are the tax consequences of owning a PFIC without making an election?
If no QEF or mark-to-market election applies, the default excess-distribution rules may govern. The calculation can allocate amounts across the holding period and add an interest charge; the result depends on the fund, dates, basis, distributions, and elections. Form 8621 treatment should be reviewed before selling or changing an election.
