Form 8621: Who Must File and How to Report PFICs

Foreign mutual funds and ETFs can look like perfectly ordinary investments—until the U.S. tax rules classify them as Passive Foreign Investment Companies (PFICs). When that happens, you may need to file Form 8621, report income each year and follow a tax regime that bears little resemblance to the rules for U.S. funds.

At Bright!Tax, we regularly meet Americans who discovered the PFIC rules only after investing through a local brokerage account, pension or savings plan. The important questions are whether your investment qualifies as a PFIC, whether you must file Form 8621 and which tax treatment applies. Let’s work through them.

What is IRS Form 8621?

Form 8621, officially titled Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund, is used to report certain direct and indirect interests in PFICs.

A PFIC is a foreign corporation that meets at least one of two tests:

PFIC test	A foreign corporation qualifies when…
Income test	At least 75% of its gross income is passive income
Asset test	At least 50% of the average percentage of its assets produces—or is held to produce—passive income

Passive income commonly includes interest, dividends, rents, royalties and certain capital gains. The rules contain important exceptions and look-through provisions, so the label attached to an investment in your country does not determine its U.S. tax treatment.

Many foreign mutual funds and ETFs qualify as PFICs because they hold investments that generate passive income. Certain investment companies, holding companies and pooled funds can also meet the tests.

But not every foreign investment is a PFIC. The entity must be treated as a foreign corporation for U.S. tax purposes and meet at least one of the statutory tests.

Consider Sophie, an American living in France who invests €20,000 in a French ETF through her local brokerage account. The ETF is ordinary by French standards, but if it is treated as a foreign corporation and meets the PFIC tests, Sophie may have Form 8621 reporting in addition to any FBAR or Form 8938 requirements.

Who must file Form 8621?

Under the IRS filing rules, a U.S. person who is a direct or indirect PFIC shareholder generally files Form 8621 when one of the following applies:

Filing trigger	What it means
PFIC distribution	You receive certain direct or indirect distributions from the PFIC
Sale or disposition	You recognize gain from selling or otherwise disposing of PFIC stock
QEF reporting	You report information under a Qualified Electing Fund election
Mark-to-market reporting	You report information under a section 1296 mark-to-market election
Another PFIC election	You make an election reported in Part II
Annual reporting	You must report PFIC ownership under section 1298(f)

A separate Form 8621 is generally required for each PFIC held directly or indirectly. If you own five reportable foreign funds, that can mean five forms.

Does every PFIC owner have to file?

No. Form 8621 includes several exceptions, although they are narrower than they first appear.

For example, the Form 8621 instructions provide an exception from completing Part I for a particular section 1291 fund when:

• The total value of relevant PFIC stock is $25,000 or less on the final day of the tax year
• The combined threshold is $50,000 for taxpayers filing jointly
• The shareholder received no excess distribution and recognized no gain from disposing of the PFIC during the year

A separate exception may apply when the value of a particular indirectly owned section 1291 fund is $5,000 or less.

These are not universal Form 8621 filing thresholds. They apply only to specific annual-reporting requirements and do not remove filing obligations triggered by distributions, dispositions or elections.

For example, imagine Elena, an American living in Spain, owns $18,000 of a Spanish investment fund. She received no distributions, made no election and did not sell any shares during the year. She may qualify for the $25,000 exception from completing Part I. If she later sells the fund at a gain, however, the exception will not prevent Form 8621 reporting for that disposition.

Does indirect PFIC ownership count?

It can. You do not always need to hold PFIC shares in your own name to have a reporting obligation.

Indirect ownership can arise through:

• A foreign partnership
• A trust or estate
• An S corporation
• Another PFIC
• Certain non-PFIC foreign corporations

The IRS attribution rules vary according to the entity. For example, a U.S. person can be an indirect PFIC shareholder through a foreign partnership that owns the investment. Ownership through a non-PFIC foreign corporation generally requires the U.S. person to own at least 50% of that corporation.

We sometimes see this when an American owns part of a family business abroad. Ravi, for example, might own an interest in an Indian partnership that invests spare cash in local mutual funds. Although Ravi never purchased those funds personally, his indirect ownership can still create Form 8621 reporting.

The rules become more complicated when several entities sit between the U.S. taxpayer and the PFIC. A chain of ownership can require a separate form for more than one PFIC in that chain.

How is PFIC income taxed?

PFIC taxation generally falls under one of three regimes:

Tax treatment	When it applies	Basic result
Section 1291 excess-distribution rules	The default when no valid QEF or mark-to-market election applies	Certain distributions and disposition gains are allocated across the holding period, with ordinary-rate tax and an interest charge applying to prior PFIC years
Mark-to-market election	Available for eligible marketable PFIC stock	Annual appreciation is ordinary income; qualifying losses are deductible within specified limits
Qualified Electing Fund election	Available when the PFIC provides the necessary information	The shareholder reports their share of ordinary earnings and net capital gain annually

The right approach depends on the investment, when you purchased it, the information available from the fund and whether an election can still be made effectively.

The default section 1291 rules

If no valid QEF or mark-to-market election applies, the investment is generally treated as a section 1291 fund.

Under the IRS section 1291 rules, an excess distribution is the portion of a current-year distribution exceeding 125% of the average distributions received during the previous three years—or the shorter portion of your holding period before the current year.

The rules for a sale are different: all gain recognized from disposing of section 1291 fund stock is treated as an excess distribution. The 125% test does not apply to the sale gain.

The excess distribution or gain is allocated across each day of your holding period:

• The amount allocated to the current year is included as ordinary income.
• Amounts allocated to certain years before the corporation became a PFIC are also included as ordinary income.
• Amounts allocated to prior PFIC years are taxed using the highest rate in effect for each applicable year.
• An interest charge applies to the tax allocated to those prior PFIC years.

That can make a seemingly modest gain surprisingly expensive.

Suppose Marcus, an American living in Portugal, sells a foreign investment fund after holding it for eight years. He never made a QEF or mark-to-market election. His entire gain is treated as an excess distribution and allocated over the holding period rather than receiving straightforward long-term capital-gain treatment.

The mark-to-market election

The mark-to-market election is available only for marketable PFIC stock. According to the Form 8621 instructions, this generally includes stock regularly traded on a qualifying U.S. or foreign exchange and certain other eligible PFIC interests.

Under a valid section 1296 election:

• Annual appreciation above your adjusted basis is reported as ordinary income.
• Your basis increases by the amount included in income.
• A decline in value can produce an ordinary deduction, but only up to your unreversed mark-to-market inclusions from previous years.
• Additional losses are subject to the tax rules that otherwise apply.

The election does not automatically erase PFIC history. If it is made after the first PFIC year, the transition into mark-to-market treatment can trigger section 1291 tax.

Daniel, an American working in Germany, bought shares in an exchange-traded foreign fund in 2026. If the shares qualify as marketable stock and he makes a timely election, he will report annual changes in value instead of waiting until the investment is sold. Whether that produces a better result depends on the fund’s performance and his wider tax position.

The Qualified Electing Fund election

A QEF election allows a shareholder to report their share of the PFIC’s earnings annually:

• Ordinary earnings are included as ordinary income.
• Net capital gain is reported as long-term capital gain.
• Income can be taxable even when the PFIC makes no cash distribution.
• Basis adjustments prevent the same income from being taxed again when it is later distributed.

To make and maintain the election, the PFIC generally must provide a PFIC Annual Information Statement, Annual Intermediary Statement or permitted combined statement containing the figures needed for the calculation. The IRS QEF instructions explain the information and documentation required.

Not all foreign funds provide this information. Without it, a QEF election may not be available.

One of our clients might come to us with a Canadian fund that supplies annual PFIC statements. In that situation, we can assess whether a timely QEF election is available and calculate the shareholder’s annual inclusions. A neighbouring fund from the same provider might supply no PFIC statement at all, leaving the investor with fewer options despite the investments appearing almost identical.

A QEF election made in the first PFIC year creates what is commonly called a pedigreed QEF. A later election does not automatically remove the PFIC treatment from earlier years; a purging election or retroactive relief may be needed.

Can you make a late QEF election?

Only in limited circumstances.

A shareholder normally makes a QEF election by the due date, including extensions, for the return covering the election year. The shareholder must properly complete Form 8621 and have the required PFIC or intermediary statement.

Revenue Procedure 2026-10 explains how certain taxpayers can request IRS consent for a retroactive QEF election. Eligibility can require the shareholder to demonstrate that:

• They reasonably relied on a qualified tax professional
• The adviser failed to identify the corporation as a PFIC or explain the QEF election
• Granting relief would not prejudice the U.S. government
• The request was made before the IRS raised the PFIC’s status during an examination
• The procedural and documentation requirements are satisfied

This is not an automatic late-election programme. It is a formal ruling request that can require detailed statements, supporting calculations, professional affidavits and a user fee.

The 2026 procedure does, however, clarify reduced-fee options for some taxpayers and for substantially identical requests involving multiple PFICs.

How do you complete Form 8621?

The revised form contains six main sections:

Section	What it covers
Part I	Summary of annual PFIC information
Part II	PFIC elections
Part III	Income from a QEF
Part IV	Gain or loss under a section 1296 mark-to-market election
Part V	Distributions and dispositions involving a section 1291 fund
Part VI	Status of a section 1294 election to extend payment of tax

Not every filer completes every part. The sections you use depend on why you are filing and which tax regime applies.

1. Gather your PFIC records

Before preparing the form, gather:

• The foreign corporation or fund’s name and address
• Your acquisition dates
• The number and class of shares held
• Your adjusted basis
• Year-end values
• Distribution and sale records
• Details of direct and indirect ownership
• PFIC Annual Information Statements, where available
• Records of relevant foreign taxes
• Copies of earlier Forms 8621 and elections

If foreign tax was charged on PFIC income, keep the supporting documents. A foreign tax credit may be available, but the result depends on the PFIC regime, income category and timing of the U.S. and foreign tax.

2. Determine why you are filing

Identify the filing trigger before filling in the form. You may be:

• Reporting annual PFIC ownership
• Reporting a distribution
• Reporting a sale or other disposition
• Making or maintaining a QEF election
• Making or maintaining a mark-to-market election
• Making another election in Part II

This step matters because Form 8621 is not a menu from which you simply choose whichever tax method looks cheapest. Each election has its own eligibility, documentation and timing rules.

3. Complete a form for each PFIC

A separate Form 8621 is generally required for each reportable PFIC. This includes indirectly owned PFICs when the attribution and filing rules apply.

The 2025 revision also added currency-reporting fields to Part V. Filers reporting relevant distributions must enter the applicable three-letter currency code and convert specified amounts into U.S. dollars.

4. File it with the appropriate return

The IRS filing instructions require you to attach Form 8621 to the shareholder’s applicable federal tax return and file both by the return’s due date, including extensions.

Depending on the filer, that could be:

• Form 1040
• Form 1120
• Form 1065
• Form 1120-S
• A trust, estate or exempt-organization return

If you are not otherwise required to file an income tax or other return, you file Form 8621 separately with the IRS service centre in Ogden, Utah.

Is Form 8621 the same as FBAR or Form 8938?

No. The forms serve different purposes, and filing one does not automatically satisfy the others.

Requirement	Form 8621	FBAR	Form 8938
Main purpose	Reports PFIC interests, transactions and elections	Reports qualifying foreign financial accounts	Reports specified foreign financial assets
Where it is filed	With an applicable IRS return, or separately when no return is required	Through FinCEN’s BSA E-Filing System	With the federal income tax return
Main threshold	Depends on the filing trigger and applicable exception	More than $10,000 across reportable foreign accounts	Varies by filing status and residence
What can trigger it	PFIC ownership, distributions, dispositions or elections	Financial interest in or authority over foreign accounts	Ownership of specified foreign financial assets

Sophie’s French brokerage account, for example, could create three separate reporting questions:

1. Does the ETF require Form 8621?
2. Does the account belong on her FBAR?
3. Does the investment count toward her Form 8938 threshold?

The answers are determined separately.

What happens if you fail to file Form 8621?

Form 8621 does not currently carry a specific standalone monetary failure-to-file penalty. That does not make an omitted form harmless.

Possible consequence	What actually happens
Assessment period remains open	Failing to report required PFIC information can suspend the IRS assessment period until three years after the information is supplied
Section 1291 treatment	If no valid QEF or mark-to-market election applies, distributions and disposition gains can fall under the default section 1291 rules
Lost or delayed election	Missing the deadline can prevent an otherwise useful election from taking effect when intended
Corrective work	Earlier returns and Forms 8621 may need to be prepared or amended

The IRS guidance on Form 8621 omissions explains that failing to report required PFIC information can suspend the assessment period. When the failure is due to reasonable cause rather than willful neglect, the extension may be limited to items connected with the missing information. Without reasonable cause, its reach can be broader.

If you discover an unreported PFIC, don’t file a collection of forms without first understanding the tax treatment. At Bright!Tax, we begin by establishing what the investment is, when it was acquired, whether distributions or sales occurred and whether any elections or exceptions apply. Those facts determine the correction—not the other way around.

Staying compliant with PFIC reporting

PFIC reporting becomes much easier when the investment is identified before the first U.S. return covering it is filed. That gives you time to obtain the fund’s documents, consider available elections and start tracking basis correctly.

If you already own a foreign mutual fund, ETF or investment company, Bright!Tax can review its classification, determine whether Form 8621 is required and coordinate the reporting with your U.S. tax return, FBAR and Form 8938.
