General information, not tax advice. Tax rules depend on your facts; talk to a qualified tax adviser before acting.
The short answer: a PFIC (passive foreign investment company) is a non-US corporation where at least 75% of gross income is passive or at least 50% of assets are passive. If you are a US investor and an offshore SPV, fund or holding company you own directly or indirectly is a PFIC, you face either a punitive default tax regime or one of two elections, plus a Form 8621 for each PFIC. Holding through a US SPV does not switch the rules off.
This guide covers the two tests, how the three tax regimes work, what changes when a US partnership sits in the chain, and the questions to raise before a US investor joins an offshore structure. It is written for SPV managers and investors, not as tax advice.
PFIC rules for US investors in offshore SPVs and funds.
What is a PFIC?
A PFIC is a foreign (non-US) corporation that meets either of two tests for a tax year, per the IRS Instructions for Form 8621:
Income test: 75% or more of the corporation's gross income is passive income, such as dividends, interest and certain gains.
Asset test: at least 50% of the corporation's assets, on average, produce passive income or are held to produce it.
Many investment vehicles formed as corporations outside the US meet one of these tests by design, because their whole job is to hold investments. A Cayman exempted company that holds a portfolio of minority stakes is a typical example. A Cayman LP or an LLC that elects partnership treatment is not a corporation for US tax purposes, so the analysis looks through it to what it owns.
The two tests. Source: IRS Instructions for Form 8621 (Rev. 12/2025), fetched Nov 2, 2026.
Why PFIC rules matter for SPV investors
The PFIC rules exist to stop US taxpayers deferring US tax by parking passive investments in offshore companies. For SPV and fund investors, they matter in three common setups:
Offshore feeder or blocker corporations. A US investor who buys shares of a non-US corporate feeder is a direct PFIC shareholder if the feeder is a PFIC.
US SPV buying shares of a non-US holding company. The US SPV is a shareholder, and its US partners are indirect shareholders.
Offshore operating companies with large cash balances. A startup that raised a big round and holds mostly cash can, in some years, fail the asset test. This one is less obvious and needs diligence on the target.
If you are forming an offshore vehicle, our Cayman Islands SPV and fund setup guide covers the structure side. This article covers the US tax consequences for US holders.
The three PFIC tax regimes
A US shareholder of a PFIC is taxed under one of three regimes. Which one applies depends on elections and on whether the stock is marketable.
Regime | How income is taxed | What you need |
|---|---|---|
Section 1291 fund (default) | Excess distributions and gains on sale are spread over the holding period, taxed at the highest rate for each prior year, plus an interest charge | Nothing; this applies if no election is made |
QEF election (section 1295) | Each year you include your share of the PFIC ordinary earnings and net capital gain, whether or not distributed | A PFIC Annual Information Statement from the company |
Mark-to-market (section 1296) | Each year, gain in value of the stock is ordinary income; some losses allowed | Stock must be marketable, which rules out most private SPV shares |
Three regimes. Source: IRS Instructions for Form 8621, fetched Nov 2, 2026.
How the default section 1291 regime works
Under the default regime, an excess distribution is the part of a distribution in a year that exceeds 125% of the average distributions over the three prior years (or the holding period, if shorter). The excess, and any gain on sale, is allocated across each day of the holding period. Amounts allocated to prior PFIC years are taxed at the highest rate in effect for that year, not at your actual rate, and an interest charge applies as if the tax had been paid late. The Form 8621 instructions give 37% as the highest individual rate for 2018 to 2025.
For a venture-style investment that pays no dividends and is sold after several years, almost the whole gain can end up as an excess distribution. That is why the default regime is usually the outcome advisers try to avoid.
How the QEF election works
A qualified electing fund (QEF) election lets a US shareholder include its share of the PFIC's ordinary earnings and net capital gain each year instead. Capital gain keeps its character. The catch is information: the PFIC (or an intermediary) must provide an annual information statement with the numbers. Many offshore vehicles agree to provide one when they expect US investors; many operating companies do not.
Mark-to-market
The mark-to-market election is available only for marketable stock, generally stock regularly traded on a qualified exchange. Private SPV interests and startup shares almost never qualify.
PFIC rules when a US SPV sits in the chain
Many syndicate leads use a US LLC or LP SPV taxed as a partnership to invest in a non-US company. The Form 8621 instructions cover interest holders in pass-through entities, so US partners can be indirect PFIC shareholders. Two practical points follow:
The partnership can make the QEF election. The instructions say a QEF election by a domestic partnership is made in its capacity as shareholder, and the partners then take the income into account through the partnership.
The income shows up on the K-1. If the SPV makes a QEF election, QEF inclusions flow to partners on Schedule K-1. Read our guide to SPV K-1s and taxes for how the K-1 package works.
Tax-exempt and retirement account holders are treated differently. The instructions state that a person holding PFIC stock through an IRA or a qualified plan described in section 401(a) is not treated as a shareholder for these purposes.
Form 8621: who files and when
Form 8621 is filed with the US shareholder's income tax return. A separate form is generally required for each PFIC. The instructions include exceptions from completing Part I where the aggregate value of a shareholder's PFIC stock is $25,000 or less ($50,000 for joint filers), or the value of indirect PFIC stock is $5,000 or less, provided conditions are met, such as no excess distribution or gain in the year. Elections such as QEF are made on Form 8621 too, and timing matters: a late election can leave earlier years in the default regime.
Questions to ask before US investors join an offshore deal
Is the vehicle or the target a corporation for US tax purposes, or a partnership or disregarded entity?
Could the target meet the income or asset test in any year, including years with large cash balances?
Will the company or vehicle provide a PFIC Annual Information Statement each year?
If a US SPV holds the shares, will the SPV make a QEF election, and who prepares the inclusions?
Do any investors hold through IRAs, and does that change the analysis?
Who files Form 8621 for each investor, and does the K-1 package give them what they need?
Non-US structures raise other tax questions too, such as withholding on non-US investors. See FIRPTA and non-US investor withholding in an SPV.
How Allocations fits
Allocations forms and administers SPVs and funds, including deals in international assets. The fee schedule lists international assets at +$1,000, a Standard SPV at $9,950 one-time and a Premium SPV at $19,500. K-1s are part of SPV administration on the platform. Allocations does not give tax advice, and PFIC determinations and elections belong with your tax adviser. [NEEDS FACT: does Allocations' tax partner prepare QEF inclusions or Form 8621 support for SPVs holding PFIC shares?]

FAQ
What is a PFIC?
A passive foreign investment company is a non-US corporation that meets either of two tests in a tax year: 75% or more of its gross income is passive, or at least 50% of its assets produce or are held to produce passive income. US shareholders of a PFIC face special tax rules and reporting on Form 8621.
Does PFIC apply if I invest through a US SPV?
It can. The Form 8621 instructions cover indirect shareholders, including interest holders in US pass-through entities such as partnerships. If a US LLC or LP SPV owns shares of a non-US corporation that is a PFIC, its US investors may be indirect PFIC shareholders.
Who makes the QEF election when a US partnership holds the PFIC?
The instructions say a QEF election made by a domestic partnership is made in the partnership's capacity as a shareholder of the PFIC. The partners then take the QEF income into account through the partnership, usually on their Schedule K-1.
Are non-US investors affected by PFIC rules?
The PFIC regime applies to US persons. A non-US investor in an offshore vehicle is generally not subject to it, but a US investor in the same vehicle may be. Mixed investor bases are where planning matters most.
Is there a minimum below which Form 8621 is not needed?
The instructions include exceptions from completing Part I: one where the aggregate value of a shareholder's PFIC stock is $25,000 or less ($50,000 on a joint return) and one for indirect PFIC stock worth $5,000 or less, each with conditions such as no excess distribution or gain in the year. Check the conditions with a tax adviser.
