If your foreign corporation shares fall under the Passive Foreign Investment Company rules, there are two routes out: statutory PFIC exceptions that keep the corporation from being classified as a PFIC in the first place, and shareholder elections that swap the punitive default tax regime for straightforward annual taxation. The right path depends on what the corporation does, who owns it, and what information you can get from it.
When PFIC Classification Kicks In
A foreign corporation is a PFIC if at least 75% of its gross income is passive, or at least 50% of its assets produce passive income.1Office of the Law Revision Counsel. 26 U.S. Code 1297 – Passive Foreign Investment Company “Passive income” borrows the foreign personal holding company definition: dividends, interest, rents, royalties, annuities, gains from selling assets that produce those items, commodity and currency gains, and income from notional principal contracts.2Office of the Law Revision Counsel. 26 U.S. Code 954 – Foreign Base Company Income The definition is broad enough to catch foreign mutual funds and ETFs that most investors don’t think of as passive.
A few income categories are carved out before you even get to the exceptions below. Rents and royalties from an active business with unrelated parties are not passive. Interest earned by a licensed bank in active banking is excluded, as is active insurance income from a qualifying insurance corporation. Income from a related company is not passive to the extent it traces back to that related company’s own active business income.1Office of the Law Revision Counsel. 26 U.S. Code 1297 – Passive Foreign Investment Company A corporation that looks passive on the surface may fall outside the rules once you trace where its income actually comes from.
Statutory Exceptions That Avoid PFIC Classification Entirely
The cleanest escape is never qualifying as a PFIC at all. These rules bypass the entire framework rather than softening it.
The Start-Up Exception
A newly formed foreign corporation gets a pass for its first taxable year with gross income if three conditions are met: no predecessor was a PFIC, the corporation establishes to the IRS that it will not be a PFIC in the two following years, and it actually avoids PFIC status in those two years.3Office of the Law Revision Counsel. 26 U.S. Code 1298 – Special Rules
The practical effect is a three-year window. Fail either follow-up year and the exception collapses retroactively, treating the company as a PFIC from year one. This matters most for companies holding large cash balances while they build out active operations. The clock starts the moment gross income appears, so the business plan needs a credible path to active operations within three years.
The Look-Through Rule for Subsidiaries
A foreign holding company whose assets are mostly subsidiary stock would fail the asset test immediately, because stock is inherently passive. The look-through rule prevents this. When a foreign corporation owns at least 25% by value of another corporation’s stock, the parent is treated as directly holding its proportionate share of the subsidiary’s assets and earning its proportionate share of the subsidiary’s income.1Office of the Law Revision Counsel. 26 U.S. Code 1297 – Passive Foreign Investment Company
If a foreign holding company owns 100% of a manufacturing subsidiary, the subsidiary’s equipment and sales revenue flow up to the parent for PFIC testing. The 25% threshold is measured by value, and the rule applies directly and indirectly through ownership chains.4eCFR. 26 CFR 1.1297-2 – Special Rules Regarding Look-Through Subsidiaries and Look-Through Partnerships No election is needed; the rule applies automatically and must be used consistently whenever PFIC status is tested.
The CFC Overlap Rule
Some foreign corporations qualify as both a PFIC and a Controlled Foreign Corporation. The anti-overlap rule stops the same shareholder from being caught by both regimes. During the portion of your holding period when the corporation is a CFC and you qualify as a “U.S. shareholder” (meaning you own at least 10% by vote or value), the corporation is simply not treated as a PFIC with respect to you.1Office of the Law Revision Counsel. 26 U.S. Code 1297 – Passive Foreign Investment Company
The exemption is shareholder-specific. A 10% owner gets CFC treatment and avoids the PFIC rules; a 5% owner of the same corporation stays stuck with PFIC treatment. For tax years beginning on or after January 25, 2022, the 10% test is applied at the partner or S corporation shareholder level when the CFC is held through a domestic passthrough entity, rather than at the entity level.
Staying Below the 50% Asset Threshold
The asset test itself provides cushion. A corporation only triggers PFIC status if 50% or more of its assets are passive, so a company sitting at 49% avoids the classification. The percentage uses the average fair market value of assets held during the year. Publicly traded corporations must use market value; others may use adjusted basis for assets used in a trade or business.1Office of the Law Revision Counsel. 26 U.S. Code 1297 – Passive Foreign Investment Company
Companies operating near the line need to watch asset valuations closely. A spike in cash reserves, a drop in the value of operating assets, or a shift in investment allocation can push a borderline company over. Measurement often happens quarterly, so a single bad quarter can tip the annual average.
What You’re Avoiding: The Default Regime
These exceptions and elections matter because the default rules under IRC Section 1291 are deliberately punitive. Distributions above 125% of your three-year average, plus any gain from selling PFIC stock, are “excess distributions.” The excess amount is spread ratably across your entire holding period and allocated to prior years. The amounts allocated to prior years are taxed at the highest individual or corporate rate in effect for each of those years, regardless of your actual bracket, and interest runs on each prior year’s deemed tax from the original due date of that year’s return.5Office of the Law Revision Counsel. 26 U.S. Code 1291 – Interest on Tax Deferral Even modest gains can generate tax bills well above the actual economic profit, which is why the elections below exist.
Elections That Replace the Default Regime
When the corporation unambiguously qualifies as a PFIC and no statutory exception applies, you can still escape the excess distribution regime with one of two elections.
The Qualified Electing Fund Election
The QEF election is the better option when it’s available. You include your proportionate share of the PFIC’s ordinary earnings as ordinary income and your share of its net capital gains as long-term capital gains each year.6Office of the Law Revision Counsel. 26 U.S. Code 1293 – Current Taxation of Income From Qualified Electing Funds Because the income is picked up annually, there is no deferral, no interest charge, and no retroactive allocation. Capital gains keep their character and flow through at preferential rates. Later distributions of already-included earnings are generally tax-free.
The catch is information. The PFIC must give you an Annual Information Statement showing your pro rata share of ordinary earnings and net capital gains. Getting that statement from a foreign corporation with no obligation to cooperate with U.S. tax reporting is often the hardest part. Publicly traded foreign companies rarely provide it. Closely held companies sometimes will, especially when U.S. investors have leverage to request it. The election is generally irrevocable without IRS consent, so confidence in ongoing information access matters before you commit.
The Mark-to-Market Election
When the QEF election isn’t practical, the mark-to-market election under IRC Section 1296 is the alternative for marketable stock. “Marketable” means regularly traded on an SEC-registered national securities exchange or another qualifying market.1Office of the Law Revision Counsel. 26 U.S. Code 1297 – Passive Foreign Investment Company That restriction effectively limits the election to publicly traded foreign corporations.
Each year you recognize ordinary income equal to the increase in your stock’s fair market value from the start to the end of the year. If value drops, you can recognize a loss, but only up to the amount of gains you previously included under the election for that same stock. Losses beyond that are deferred. Because the mechanism uses only public market prices, no cooperation from the corporation is needed. The cost: all gains are ordinary, not capital. For a long-held appreciated position, that can mean a materially higher tax bill than QEF.
Choosing Between Them
If the PFIC will provide the Annual Information Statement and you plan to hold long term, QEF almost always wins; the capital gains rate differential compounds over years. Mark-to-market is the fallback when the PFIC won’t cooperate, which covers most publicly traded foreign funds and ETFs. Making either election after years of untaxed holding requires dealing with the built-up gain through a deemed sale or deemed dividend.
The “Once a PFIC, Always a PFIC” Trap
An exception that applies today does not erase prior PFIC years. If the corporation qualified as a PFIC at any point during your holding period and was not a qualified electing fund during that time, the stock continues to be treated as PFIC stock for as long as you hold it, even after the company stops meeting the income or asset tests.3Office of the Law Revision Counsel. 26 U.S. Code 1298 – Special Rules
The only way to break the taint is a “purging election.” You can elect a deemed sale, recognizing gain as if you sold the stock on the last day of the company’s final PFIC year, or a deemed dividend, including a calculated amount as an excess distribution. Both trigger immediate tax and interest under the excess distribution rules but clean the slate going forward.7eCFR. 26 CFR 1.1298-3 – Deemed Sale or Deemed Dividend Election by a U.S. Person That is a Shareholder of a Former PFIC You make either election on Form 8621 with the return for the year the company stopped being a PFIC, with a three-year window from the original due date if you file by amended return. Skip the purging election and the excess distribution rules keep applying to all future distributions and gains, even though the company is no longer a PFIC.
Form 8621 Still Applies
Qualifying for an exception or making an election does not get you out of the paperwork. Every U.S. shareholder of a PFIC must file Form 8621 with their annual return, one form per PFIC, whether they are relying on a statutory exception, an election, or the default regime.8Internal Revenue Service. About Form 8621, Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund A narrow filing exception exists where total PFIC holdings are worth $25,000 or less ($50,000 on a joint return) and certain other conditions are met.9eCFR. 26 CFR 1.1298-1 – Section 1298(f) Annual Reporting Requirements for United States Persons That Are Shareholders of a Passive Foreign Investment Company Above that, or if you’re making an election, the form is required.
The real cost of skipping it is procedural. Under IRC Section 6501(c)(8), the statute of limitations on your entire tax return stays open until three years after you finally provide the information.10Office of the Law Revision Counsel. 26 U.S. Code 6501 – Limitations on Assessment and Collection The IRS can audit any item on that return indefinitely while the form is missing. Reasonable cause narrows the open period to PFIC items only, but proving it after the fact is difficult. Filing on time, even when no tax is due, is the cheapest protection available.
