A PFIC is a foreign corporation meeting a passive-income or passive-asset test, potentially triggering specialized U.S. shareholder tax and reporting rules.
A passive foreign investment company (PFIC) is a foreign corporation that meets either the U.S. tax law’s passive-income test or passive-asset test for a taxable year. U.S. shareholders can face specialized income-recognition, election, basis, distribution, disposition, and Form 8621 reporting rules.
PFIC status matters because an investment that looks like an ordinary foreign mutual fund, exchange-traded fund, holding company, or startup can produce tax treatment very different from a comparable U.S. investment. A small ownership interest can be enough; PFIC classification is not based on the shareholder controlling the corporation.
75% passive-income test or the 50% passive-asset test.A foreign corporation generally qualifies as a PFIC for a taxable year if either test is met:
| Test | General threshold | Core question |
|---|---|---|
| Income test | 75% or more of gross income is passive income | What types of income did the corporation earn during the year? |
| Asset test | 50% or more of the average percentage of assets produce passive income or are held to produce it | What assets did the corporation hold, how were they valued, and what income were they expected to produce? |
Passive income generally draws from foreign personal holding company income concepts and can include interest, dividends, certain rents and royalties, and gains from property producing passive income. Exceptions and look-through treatment can apply, so a financial-statement label such as “investment income” is not a complete tax classification.
For the asset test, the valuation method and measurement periods matter. Public-market value, adjusted basis, lower-tier ownership, goodwill, cash, and assets used in an active business can require detailed analysis.
Assume Foreign Corporation A earns $8 million of gross income, of which $6.2 million is passive income.
| Calculation | Result |
|---|---|
| Passive income percentage | $6.2m / $8.0m = 77.5% |
| Income-test threshold | 75.0% |
On these simplified facts, the corporation meets the income test and can be a PFIC even if it does not meet the asset test. If passive income were below 75%, the asset test would still need to be evaluated independently.
The example assumes the amounts are classified correctly and ignores look-through rules, exceptions, and entity-specific facts.
Without an effective QEF or mark-to-market election, a U.S. shareholder generally applies section 1291 rules to excess distributions and gain recognized on a disposition. The calculation can allocate amounts across the holding period, apply specified tax treatment to prior-year allocations, and add an interest charge.
The cash distribution alone does not reveal the result. Acquisition dates, annual distributions, PFIC years, basis, prior elections, and indirect ownership records are important.
Under a valid QEF election, a shareholder generally includes a share of the PFIC’s ordinary earnings and net capital gain annually, whether or not cash is distributed. Basis is adjusted to reflect inclusions and certain distributions.
The election normally requires information supplied by the PFIC. A fund that does not provide a compliant annual information statement may make a QEF election impractical. Timing also matters because a late election may not eliminate all consequences of prior PFIC years without additional procedures.
A mark-to-market election is generally limited to marketable PFIC stock meeting the applicable requirements. Annual increases can be included as ordinary income, while decreases can produce an ordinary loss only within specified limits tied to prior inclusions. Basis is adjusted for recognized amounts.
Exchange listing alone should not be treated as proof that all election requirements are met. The market, security, holding structure, and effective election year must be checked.
| Regime | Timing | Character and cash-flow issue | Main evidence need |
|---|---|---|---|
| Section 1291 default | Generally on excess distribution or disposition | Prior-year allocation and interest-charge mechanics can apply | Complete holding-period and distribution history |
| QEF | Annual inclusion of specified earnings and gains | Tax can arise before cash is received | PFIC annual information statement and timely election |
| Mark-to-market | Annual recognition based on fair-market-value changes | Ordinary-income treatment and limited ordinary losses can apply | Marketability, year-end value, basis, and election record |
No regime is universally preferable. Investment horizon, expected returns, cash distributions, loss outcomes, information availability, and the shareholder’s broader tax position can change the comparison.
| Feature | PFIC | CFC |
|---|---|---|
| Entity | Foreign corporation | Foreign corporation |
| Main test | Passive income or passive assets | More-than-50% ownership by qualifying U.S. shareholders under applicable attribution rules |
| Minimum owner control for classification | No shareholder-control threshold in the PFIC tests | Control test is central |
| Main policy focus | Passive foreign investment and deferral | U.S.-controlled foreign corporate income |
| Common reporting form | Form 8621 | Form 5471 for applicable filer categories |
Special overlap rules can coordinate PFIC and CFC treatment for some U.S. shareholders and periods. The table is not sufficient to resolve an overlapping case.
Assuming a foreign mutual fund is taxed like a U.S. fund. Foreign pooled investments are a common PFIC risk area.
Checking only the income test. Either the income test or asset test can independently produce PFIC status.
Waiting for a distribution. Classification, annual information, election, and reporting questions can arise before cash is received.
Assuming a QEF election is always available. The shareholder generally needs qualifying information from the fund or corporation.
Treating market-to-market accounting as a tax election. Financial-statement fair-value treatment does not create a federal tax mark-to-market election.
Ignoring indirect holdings. Partnerships, trusts, estates, other corporations, and tiered PFICs can create indirect-shareholder issues.
Losing historical records. Basis, acquisition lots, prior PFIC years, distributions, annual statements, and elections can affect later calculations.
