Form 8621: Information Return by a Shareholder of a PFIC

Form 8621 reports U.S. shareholder interests in Passive Foreign Investment Companies (PFICs) and QEF elections. If you own a foreign mutual fund, foreign ETF, or certain foreign insurance products, you may be holding a PFIC and need to assess the filing requirement. This guide walks through what PFICs are, how to identify them, and how to file Form 8621 correctly.

What Is a PFIC?

A PFIC is a foreign corporation that meets either of these two tests:

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

In practice, most foreign mutual funds, foreign ETFs, and unit trusts are PFICs. The IRS designed these rules to prevent US taxpayers from deferring tax on passive income inside offshore investment vehicles.

Common PFICs for Expats

• Foreign mutual funds (UK OEICs, UCITS funds in Europe, Australian managed funds)
• Foreign ETFs listed on non-US exchanges
• Foreign hedge funds and private equity funds
• Investment-linked insurance arrangements whose contract and ownership facts cause the U.S. person to be treated as owning shares of a foreign corporation
• Foreign pension wrappers that invest in pooled funds (analyzed separately with ownership and look-through facts)

Not PFICs: Direct ownership of individual foreign stocks, US-based mutual funds, and most foreign real estate held directly.

The Three PFIC Tax Regimes

When you hold a PFIC, you must choose (or default into) one of three tax regimes. The choice you make has massive consequences for your tax bill.

1. Excess Distribution Method (Default)

If you do not make an election, the excess distribution method applies automatically. This is the worst possible outcome:

• Excess distributions (distributions exceeding 125% of the average over the prior 3 years) are taxed as ordinary income at the highest marginal rate
• Interest charges apply to the deferred tax, calculated as if the tax had been due in prior years
• Dispositions (selling the PFIC) trigger the same punitive treatment on the entire gain
• Effective tax rates can exceed 50% when interest is included

This method is designed to be so unfavorable that taxpayers are forced to make an election.

2. Qualified Electing Fund (QEF) Election

The QEF election is usually the best option if available:

• You report your pro-rata share of the PFIC's ordinary income and net capital gains annually on your US return
• Gains are taxed at ordinary income rates, but there is no interest charge
• When you sell the PFIC, any gain is taxed as capital gain (not ordinary income)
• Requirement: The PFIC must provide an Annual Information Statement (AIS) with the details needed to calculate your share

The catch: Many foreign funds, especially smaller ones or those in non-treaty countries, do not provide the AIS. Without it, you cannot make a QEF election.

3. Mark-to-Market Election

Available only for PFIC stock that is regularly traded on a qualified exchange:

• You report unrealized gains annually as ordinary income
• Unrealized losses are deductible (subject to limitations)
• When you sell, any additional gain is ordinary income
• No interest charges apply
• Best for: Publicly traded foreign ETFs and stocks where QEF is unavailable

How to File Form 8621

Step 1: Identify Your PFICs

Review all foreign investment accounts and ask:

• Is this a pooled investment vehicle (mutual fund, ETF, unit trust)?
• Is it organized outside the US?
• Does it meet the income or asset test?

Use our PFIC Identification Checklist for a systematic review.

Step 2: Determine Your Tax Regime

Step 3: Make the Election on Form 8621

• Attach Form 8621 to your Form 1040
• Check the appropriate election box (QEF or Mark-to-Market)
• For QEF, attach the Annual Information Statement from the PFIC
• The election is generally irrevocable

Step 4: Report Annual Income

• QEF: Report ordinary income and capital gains from the AIS in Part III
• Mark-to-Market: Report unrealized gains/losses in Part IV
• Excess Distribution: Calculate excess distributions and deferred tax with interest in Part V

Step 5: Report Dispositions

When you sell a PFIC, report the gain or loss on Form 8621 regardless of which election you made. The character of the gain (capital vs. ordinary) depends on your election.

Special Situations

PFICs Inside Foreign Pensions

Many foreign pensions (UK SIPPs, Australian superannuation, Canadian RRSPs) invest in pooled funds that are PFICs. The tax treatment depends on:

• Whether the pension qualifies for treaty benefits
• Whether the pension is treated as a trust for US purposes
• Whether Form 8621 is required or the PFIC is "looked through"

This is one of the most complex areas of expat tax. See our PFIC Foreign Pensions Trap for details.

Indirect Ownership

You may own a PFIC indirectly through:

• A foreign corporation you control
• A foreign partnership
• A foreign trust
• Another PFIC (tiered PFICs)

Indirect ownership still triggers Form 8621 filing and the same tax regimes.

Start-Up Year and Exception

If the PFIC is in its first year of operation or is a start-up company primarily engaged in active business, it may qualify for an exception from PFIC status. This is rare for typical expat investments.

A Practical PFIC Review Workflow

The difficult part of Form 8621 is usually not typing values into the form. It is establishing what the investment is under US tax principles, identifying every year in which an ownership or reporting rule applied, and preserving the information needed to support the chosen regime. A brokerage statement that calls a product a “fund,” “savings plan,” or “insurance investment” is not enough by itself to determine the US result.

1. Build the investment inventory

Start with every non-US investment account, pension wrapper, insurance contract, mutual fund, ETF, unit trust, employer plan, and product sold during the year. Record the legal issuer, country, owner, acquisition date, number of shares, transactions, distributions, year-end value, and whether the investment is held directly or through another entity. A PFIC filing can be triggered by a disposition or distribution even when the account is empty at year-end.

2. Separate the wrapper from the underlying asset

A foreign bank account is not automatically a PFIC, while a foreign fund held inside that account may be one. The same distinction matters for pensions and insurance products. Identify whether the taxpayer owns stock in a corporation, an interest in a partnership, a beneficial interest in a trust, or units of a pooled investment. Then review whether an exception, treaty position, or look-through rule changes the analysis. Do not assume that a local tax label such as “retirement,” “tax-free,” or “accumulation” controls the US classification.

If the investment is held through a foreign policy, classify the contract and ownership chain before selecting a PFIC filing path. Start with the foreign life insurance consultation; use the PFIC consultation when direct or indirect PFIC ownership is the established primary issue.

3. Determine whether an election is available

The default excess-distribution regime may apply when there is no valid QEF or mark-to-market election. A QEF election generally depends on obtaining the PFIC’s annual information statement in the form required by the IRS. A mark-to-market election is generally limited to marketable stock and requires a suitable market and consistent reporting. The election date, first qualifying year, prior ownership, and late-election relief can change the calculation. Keep the fund statement, prospectus or legal documentation, and the workpaper explaining the conclusion.

4. Coordinate with the rest of the return

Form 8621 is rarely the only international form. The same asset may also affect Form 8938, the FBAR, Form 5471, Form 8865, Form 8858, Form 3520, or a foreign tax credit calculation. A distribution can affect both the PFIC allocation and the income reported on Form 1040. Foreign tax paid by a fund or withheld from a distribution may not be creditable in the same way as tax paid directly by the taxpayer. Review the entire ownership chain before finalizing the form.

Records to gather before a consultation

Bring annual statements, transaction history, the fund’s legal name and domicile, acquisition and sale dates, any QEF annual information statements, prior Forms 8621, Forms 1040, foreign tax slips, and documents describing pension or insurance wrappers. If records are incomplete, preserve the statements you do have and identify the missing years rather than estimating silently. The right remediation path depends on whether the omission was a missed information form, an incorrect income position, or a potentially willful failure.

Penalties and Risks

While there is no specific monetary penalty for failing to file Form 8621, the tax consequences are severe:

• Excess distribution interest charges can add 30-50% to your effective tax rate
• Mischaracterized gains (capital gains taxed as ordinary income) cost an additional 17-20% in tax
• Amended returns to make late elections are difficult and often denied
• Streamlined Filing may not fix PFIC problems if the omission was due to willful disregard
