PFIC explained: What is a PFIC, form 8621 reporting requirements & US tax rules
Passive foreign investment companies (PFICs) are foreign corporations subject to complex US tax rules that can lead to high tax rates, interest charges, and strict reporting obligations. US investors holding shares in foreign funds should understand PFIC tax rules before filing a 2025 return in 2026.
A passive foreign investment company (PFIC) is not simply any foreign investment. The PFIC rules apply to foreign corporations that meet 1 of 2 annual tests under Internal Revenue Code section 1297: a 75% passive income test or a 50% passive asset test.
For help with reporting a foreign fund, see our PFIC filing service.
For 2025 returns filed in 2026, start by identifying each foreign corporation that may be a PFIC, then check the 5 Form 8621 filing circumstances: certain distributions, gain on disposition, QEF or mark-to-market reporting, a Part II election, and annual reporting under section 1298(f). A separate Form 8621 is generally required for each PFIC unless a specific rule or exception applies.

|---|---|
| What is a PFIC | A passive foreign investment company (PFIC) is a foreign corporation that meets the 75% passive income test or the 50% passive asset test. |
| PFIC identification | PFIC testing is annual, so a foreign corporation may meet the income or asset test in one year and not another. However, for a US shareholder, stock can remain subject to PFIC rules if the corporation was a PFIC at any time during the shareholder’s holding period and was not a QEF, unless a purging election or other exception applies. |
| PFIC taxes | PFIC tax treatment usually falls under 1 of 3 regimes: default section 1291, mark-to-market, or QEF. |
| PFIC reporting | A US person may need a separate Form 8621 for each PFIC when a filing trigger applies. |
| Exceptions | The $25,000 / $50,000 low-value exception is limited and does not override sales, excess distributions, or elections. |
NOTE! Form 8621 is not automatically required every year just because you own PFIC stock.A US person generally files Form 8621 only if 1 of the IRS filing triggers applies, such as receiving certain PFIC distributions, recognizing gain on a sale, reporting a QEF or mark-to-market election, making a PFIC election, or being subject to the annual reporting rules under section 1298(f). If filing is required, a separate Form 8621 is generally filed for each PFIC.

What is a PFIC?
A PFIC is a foreign corporation that meets 1 of 2 tests for a tax year:
- at least 75% passive income or
- at least 50% passive assets.
This PFIC definition matters because US taxpayers can owe special tax, interest, and Form 8621 reporting even when the investment is held outside the United States.
A passive foreign investment company (PFIC) is a foreign corporation that primarily generates passive income, such as dividends, interest, rents, royalties, or capital gains, or holds assets that produce such income. Defined by US tax law, PFICs aim to prevent US taxpayers from avoiding or deferring taxes by investing in foreign entities not subject to the same rules as US-based companies.
The passive foreign investment company tax system applies only if the entity is treated as a foreign corporation for US tax purposes. A foreign bank account, a direct holding of non-US shares, or a personally owned rental property is not automatically a PFIC investment just because it is outside the United States.
NOTE! A PFIC is usually a non-US fund-style investment that earns mostly passive income or holds mostly passive assets. The passive foreign investment company PFIC label often catches foreign mutual funds, foreign ETFs, and pooled investment products that look ordinary in the local country but are treated very differently on a US return. The PFIC meaning is narrower than the phrase “foreign investment.” A PFIC is a foreign investment company only when it is a corporation for US tax purposes and meets the income or asset test for that year.
Also, read our guide to foreign disregarded entities and Form 8858 if your non-US structure may be treated as something other than a corporation.
How the IRS decides whether an investment is a PFIC
The IRS decides PFIC status using 2 annual tests under section 1297: the income test and the asset test. If a foreign corporation meets either test for the 2025 tax year, the PFIC rules can apply to a US shareholder filing in 2026.
A passive foreign investment company (PFIC) is a foreign corporation that meets at least 1 of 2 tests applied annually:
The following 2 PFIC testing rules determine whether a foreign corporation is a PFIC for the year:
- Income test: 75% or more of the company’s gross income is passive, such as dividends, interest, royalties, rents, or capital gains.
- Asset test: 50% or more of the company’s assets produce passive income or are held for the production of passive income.
Because these tests are applied each tax year, an investment might be considered a PFIC 1 year but not the next. You can compare this with our guide to taxation of foreign dividends, since ordinary dividend reporting and PFIC income reporting can produce very different outcomes.
The 75% income test and 50% asset test are separate gates, so meeting either one can create PFIC status for that tax year.
| PFIC test | Threshold | What counts | Example |
|---|---|---|---|
| Income test | 75% or more of gross income | Passive income such as interest, dividends, rents, royalties, and capital gains | A foreign mutual fund earns 90% of its income from dividends and capital gains. |
| Asset test | At least 50% of average assets | Assets that produce passive income or are held to produce passive income | A foreign holding company keeps most of its value in cash, securities, and fund units. |
| Look-through rule | 25% ownership by value | The foreign corporation may be treated as holding its share of another corporation’s income and assets | A foreign corporation owns 30% of a subsidiary, so its proportionate subsidiary assets may be included. |
| CFC overlap | Applies only to qualified portions | A US shareholder of a CFC/PFIC may avoid PFIC treatment for the same stock during the qualified portion of the holding period | A 10% US shareholder includes subpart F income for a CFC that also meets PFIC tests. |
Most US-based mutual funds, even those holding foreign investments, are not PFICs because PFIC rules apply only to foreign corporations. Since US mutual funds are domestic entities, they fall outside the PFIC regime.
In contrast, foreign investment funds that meet either the income or asset test and are not US-domiciled can be classified as PFICs. The statutory definition is in 26 U.S. Code section 1297, which is the core passive foreign investment company IRS authority for the 75% and 50% thresholds.
Why PFIC rules matter: higher taxes and IRS risks
PFIC rules matter because section 1291 can convert what looks like investment income into ordinary income plus an interest charge. For the 2025 tax year, the top ordinary federal income tax rate is 37%, and PFIC taxes can be harsher than ordinary capital-gain treatment.
The PFIC rules were established to prevent US taxpayers from deferring taxes on passive income earned through foreign entities.
Once an investment falls under the PFIC classification, it triggers a set of complex reporting requirements and can result in significantly higher taxes.
If you’re a US investor with PFIC holdings, you may be required to report the investment using IRS Form 8621, Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund.
Failing to file a required Form 8621 does not carry a standard fixed dollar penalty in the way some other international forms do. However, it can create serious consequences: the IRS may keep the tax year open longer under IRC section 6501(c)(8), and you may still owe additional tax, interest, and other penalties if PFIC income was reported incorrectly or omitted.
The passive foreign investment company tax result can also affect basis tracking, foreign tax credit decisions, and whether a distribution is treated as ordinary income or as a PFIC excess distribution. This is why PFIC accounting should start when the investment is purchased, not when a Form 8621 deadline is approaching.
Common PFIC examples: foreign mutual funds, ETFs & investment vehicles
Common PFIC examples include foreign mutual funds, foreign ETFs, unit trusts, some foreign REITs, pooled investment vehicles, and certain insurance wrappers. A US investor can also have indirect PFIC reporting through a partnership, trust, or K-1 if that entity owns PFIC stock.
The following 8 categories are common places where PFIC funds or indirect PFIC exposure can appear:
- foreign mutual funds
- certain hedge funds
- pooled investment vehicles
- startups with significant cash reserves
- unit trusts and investment trusts treated as foreign corporations for US tax purposes
- foreign REITs that meet the passive income or asset test
- foreign insurance wrappers that do not qualify for applicable insurance exceptions
- indirect PFIC interests reported through partnerships, trusts, or other pass-through entities
These entities primarily generate passive income, making them subject to PFIC rules. Additionally, foreign exchange-traded funds (ETFs) and offshore investment trusts are common examples.
Indirect exposure deserves a separate check. If a US person receives a Schedule K-1 from a partnership that owns foreign funds, or owns a foreign pass-through entity that holds PFIC stock, the IRS PFIC reporting rules may treat the person as an indirect shareholder.
The main distinction is domicile and entity classification: a foreign pooled fund is often PFIC risk, while a US-domiciled fund is usually outside the PFIC regime.
| Usually PFIC | Usually not PFIC | Why the distinction matters |
|---|---|---|
| Foreign mutual funds | US mutual funds | PFIC rules apply to foreign corporations, not domestic funds. |
| Foreign ETFs | US-domiciled ETFs | A PFIC ETF can trigger Form 8621 even if it holds US stocks. |
| Foreign unit trusts treated as corporations | Direct shares of an active foreign operating company are usually not PFIC stock if the company fails both PFIC tests. | Unit trusts may be pooled passive vehicles; active companies may fail both PFIC tests. |
| Offshore investment trusts | Personally owned foreign bank deposits | A bank account may trigger FBAR, but it is not automatically PFIC stock. |
| Foreign REITs with passive assets | US REITs | Foreign REIT classification depends on US tax entity treatment and the 75% / 50% tests. |
| Certain insurance wrappers | Qualifying foreign insurance companies | Insurance exceptions are fact-specific and require careful review. |
| PFIC mutual funds held through a partnership | A direct foreign rental property | A partnership can create indirect PFIC filing, while a rental property is not stock in a foreign corporation. |
However, active businesses, such as a foreign manufacturing company or an overseas retail chain, generally do not qualify as passive foreign investment companies since they generate income through operations rather than passive investments.
A foreign ETF versus a US-domiciled ETF comparison is especially important for expats. A London-listed or Ireland-domiciled ETF may be a PFIC ETF, while a US-domiciled ETF that invests internationally is generally not a passive foreign investment company because it is organized in the United States.
How PFICs are taxed: excess distribution method, QEF election & MTM rules
The taxation of PFICs can be approached using 1 of 3 main methods:
- the default section 1291 excess distribution method,
- a section 1296 mark-to-market election, or
- a section 1295 QEF election.
The right PFIC tax treatment depends on marketability, fund data, timing, and the investor’s holding period.
1. Excess distribution method
The excess distribution method is the default section 1291 PFIC method when no valid QEF or mark-to-market election applies. A current-year distribution above 125% of the average distributions from the prior 3 years can be a PFIC excess distribution, and gain on sale is generally treated the same way.
This is the default method for taxing PFICs. With this approach, any distribution that exceeds 125% of the average distributions received during the previous 3 years is considered an “excess distribution.” These excess distributions are allocated over your holding period and taxed at the highest ordinary income rate for each year, along with an additional interest charge.
For example, if you receive a PFIC excess distribution of $5,000 in the fourth year of owning a PFIC, it will be allocated across the holding period and taxed under section 1291. The longer you hold the PFIC, the more interest may accumulate on the deferred tax amount.
Gain on a sale or other disposition of section 1291 fund stock is also treated as an excess distribution. A loss on the sale does not reduce the section 1291 excess distribution amount, although it may be handled elsewhere under normal loss rules if allowed.
Based on our client scenario at TFX: A US expat in Germany bought a foreign mutual fund in 2021 and received distributions of $200, $200, and $400 in 2022 through 2024. The 3-year average was $267, and 125% of that average was about $333. When the fund paid $2,000 in 2025, roughly $1,667 was treated as an excess distribution before day-by-day allocation and interest calculations.
This PFIC taxation example shows why PFIC taxes can feel disproportionate compared with the cash received. A 1291 PFIC result can also affect a sale, because the entire gain may be treated as an excess distribution rather than as long-term capital gain.
Do not confuse a PFIC excess distribution with the IRS term “excess qualifying distributions” used for private foundations. The IRS page on excess qualifying distributions covers a different tax concept.
2. Mark-to-market (MTM) election
A mark-to-market election is available only for marketable PFIC stock under section 1296, generally stock regularly traded on a qualified exchange. Under MTM, annual gains are ordinary income, and losses are limited to prior unreversed MTM inclusions.
The mark-to-market election allows you to recognize annual gains in the value of the PFIC shares as ordinary income, whether you sold the shares or not.
The gain is based on the value of the PFIC at the end of the tax year compared to its adjusted basis. If the value decreases, you can claim a loss, but only to the extent that it offsets previously reported mark-to-market gains.
While MTM eliminates future section 1291 interest charges for covered years, it may not be the best choice if your PFIC has volatile or unpredictable annual returns. PFIC netting rules can also limit how much loss you can use after a down year.
Based on our client scenario at TFX: A US taxpayer in Singapore held a foreign ETF with an adjusted basis of $18,000 on January 1, 2025, and a fair market value of $22,000 on December 31, 2025. With a valid MTM election, the $4,000 increase was ordinary income for 2025. If the fund fell by $3,000 in 2026, the ordinary loss would generally be limited by prior unreversed MTM inclusions.
This second PFIC taxation example shows why MTM can simplify PFIC accounting but still create annual taxable income without a sale. PFIC netting rules should be reviewed before assuming a later decline will fully offset earlier PFIC tax.
3. Qualified electing fund (QEF) election
A QEF election can preserve capital-gain character for net capital gain, but it requires annual fund-level information. For the 2025 tax year, the fund or intermediary generally must provide ordinary earnings and net capital gain data that can be reflected on Form 8621.
Choosing the QEF election allows you to be taxed annually on your pro-rata share of the PFIC’s earnings, whether or not you receive a distribution.
With this option, gains from the sale of PFIC shares may receive capital-gain treatment, and you avoid the interest charges on excess distributions for properly covered years.
This method is only available if the PFIC agrees to provide detailed financial information each year, which is not always the case. Without this information, you’ll usually be stuck with the default excess distribution method unless MTM is available.
Based on our client scenario at TFX: A US expat in the UK received a PFIC Annual Information Statement showing $600 of ordinary earnings and $900 of net capital gain for 2025. With a valid QEF election, the taxpayer included $1,500 on the 2025 return even though the fund made no cash distribution, and the basis was adjusted for the inclusion.
The practical choice is data first: QEF needs annual fund information, MTM needs marketable stock, and section 1291 applies when neither election works.
| Method | Best for | Data needed | Tax character | Main downside |
|---|---|---|---|---|
| Default section 1291 | Older PFIC holdings with no QEF statement and no MTM eligibility | Distribution history, acquisition dates, sale data, holding period, foreign currency data | Excess distributions and gain are taxed under section 1291, often at highest ordinary rates plus interest | PFIC tax implications can worsen the longer the holding period lasts. |
| Mark-to-market | Publicly traded PFIC funds with reliable year-end values | Beginning basis, year-end fair market value, sale data, prior MTM inclusions | Annual gains are ordinary income; losses are limited to unreversed inclusions | Can create tax without cash and does not preserve capital-gain character. |
| QEF | Funds that provide a PFIC Annual Information Statement | Ordinary earnings, net capital gain, distributions, shareholder allocation, annual statements | Ordinary earnings are ordinary income; net capital gain can retain long-term capital-gain character | Requires fund cooperation and annual documentation. |
PFIC reporting can become complex quickly
PFIC reporting can become complex quickly if you hold foreign mutual funds, ETFs, or other non-US pooled investments. These holdings often require filing Form 8621, with strict rules on income treatment, elections, and ongoing tracking. At Taxes for Expats, our CPA-led PFIC filing service helps you identify what’s reportable, prepare accurate filings, and choose the most tax-efficient approach – so you stay compliant and avoid unnecessary penalties.
We handle the full process end-to-end, from reviewing your foreign investments and preparing each required Form 8621 to coordinating with your broader tax return, FBAR, and FATCA reporting. Whether you’re dealing with current-year filings or catching up on prior years, we help ensure your reporting is consistent, defensible, and aligned with your overall tax position.
Our PFIC specialists can review your fund documents, model the available options, and prepare Form 8621 correctly for each PFIC.
Choosing between QEF and MTM: a simple decision guide
If a timely QEF election is made for the first PFIC year, or a proper purging election fixes earlier PFIC years, QEF treatment can preserve long-term capital-gain character for net capital gain and avoid section 1291 interest for covered years. If the PFIC is an unpedigreed QEF, section 1291 can still apply.
Decision flow:
- Does the fund provide a PFIC Annual Information Statement? If yes, consider a QEF election.
- No QEF statement?
- Are the shares publicly traded (“marketable stock”)? If yes, consider MTM.
- If neither QEF nor MTM applies, you’re under default §1291 and should plan distributions/dispositions carefully.
Pros/cons snapshot:
- QEF: Preserves capital character on net gains; requires annual PFIC statement and inclusions.
- MTM: Simpler data needs; ordinary income on annual gains; loss use is limited to prior MTM gains.
How to obtain a PFIC Annual Information Statement (QEF statement) from your fund
A PFIC Annual Information Statement is usually needed for a QEF election and should be requested as early as the year-end statement is available. For 2025 filings in 2026, ask the fund or broker for ordinary earnings, net capital gain, and distribution data before preparing Form 8621.
Many global fund complexes can provide a PFIC Annual Information Statement upon request. Contact the fund’s investor relations team or your broker’s international desk early, ideally shortly after year-end.
The following 3 items are the core contents to request under the QEF rules:
- Your pro-rata share of ordinary earnings and net capital gain.
- Instructions for basis adjustments and any prior-year carryovers relevant to QEF.
- Certification that the information is provided to support a QEF election.
A complete request should also ask whether the fund can provide an Annual Intermediary Statement or a combined statement if you hold the investment through a broker, platform, partnership, or pension wrapper.
Sample email/request script
Subject: Request for PFIC Annual Information Statement for 2025 US tax reporting
Hello,
I am a US taxpayer who held shares/units of [fund name and ISIN/ticker] during the 2025 calendar year. Please confirm whether the fund is treated as a passive foreign investment company for US tax purposes and whether you can provide a PFIC Annual Information Statement or Annual Intermediary Statement for the fund’s tax year ending in 2025.
Please include my pro-rata share of ordinary earnings, net capital gain, cash distributions, deemed distributions, and any information needed to make or maintain a QEF election on IRS Form 8621. If the statement is available through a broker portal or investor relations team, please direct me to the correct contact or document library.
Thank you,
[Name]
The strongest QEF file includes 7 records before Form 8621 is prepared.
The following 7 records help support a QEF election and reduce follow-up questions during PFIC filing:
- Fund name, ISIN, ticker, country of domicile, and tax year.
- Acquisition date, number of shares or units, and cost basis in US dollars.
- Year-end fair market value and periodic account statements.
- PFIC Annual Information Statement, Annual Intermediary Statement, or combined statement.
- Ordinary earnings and net capital gain allocations for 2025.
- Cash distributions, reinvested distributions, and foreign withholding tax.
- Prior Forms 8621, prior elections, and prior basis adjustments.
PFIC reporting requirements: how to report PFIC investments
For the 2025 tax year filed in 2026, a US person files Form 8621 if 1 of the IRS triggers applies, including certain distributions, gain on disposition, a QEF or MTM election, another reportable election, or annual reporting under section 1298(f). A separate Form 8621 is generally used for each PFIC.
- If you hold shares in a PFIC, you may be required to file Form 8621 for that tax year, which is generally required if you received certain distributions or are otherwise subject to the annual PFIC reporting rules under IRS regulations.
- This form requires you to report any excess distributions, gains from the sale of PFIC shares, and any elections made, such as QEF or MTM.
- In addition to Form 8621, PFICs may also need to be reported on Form 8938, Statement of Specified Foreign Financial Assets, under FATCA regulations, as well as on the FBAR if the aggregate value of your foreign financial accounts exceeded $10,000 at any time during the calendar year.
Separately, the investment may need to be reported on Form 8938 if your total specified foreign financial assets exceeded the applicable FATCA threshold.
For more details on overlapping asset reporting, review our guide to foreign assets disclosure for US taxpayers. Also, read our full guide to FBAR filing requirements and deadlines in 2026 if the PFIC is held inside a foreign financial account.
The December 2025 Form 8621 instructions say Form 8621 is attached to the shareholder’s tax return and filed by the due date, including extensions. If the taxpayer is not required to file an income tax return or other return for the year, Form 8621 is filed directly with the IRS service center in Ogden, Utah.
For 2025 returns, Form 8621 depends on triggers – not just ownership – and indirect ownership can count.
| Trigger | Form 8621 needed? | Notes |
|---|---|---|
| Certain direct or indirect PFIC distribution | Yes, unless a specific exception applies | A distribution can create a PFIC excess distribution under section 1291. |
| Sale or other disposition with gain | Yes | Gain on a section 1291 fund is generally treated as an excess distribution. |
| QEF election or annual QEF reporting | Yes | Part III reports ordinary earnings and net capital gain. |
| Section 1296 MTM election | Yes | Part IV reports gain or loss from the mark-to-market election. |
| Making another election in Part II | Yes | Elections can include deemed sale or deemed dividend elections in specific cases. |
| Annual reporting under section 1298(f) | Yes, unless an exception applies | Low-value and certain pension exceptions may affect Part I. |
| Indirect ownership through a pass-through entity | Sometimes yes | Partnerships, S corporations, trusts, and estates can create indirect shareholder filing duties. |
| PFIC reported on Form 8938 through another form | Still check both forms | Form 8938 may require identifying Form 8621 even when details are not duplicated. |
PFIC reporting requirements can overlap with FATCA without being identical. If a specified foreign financial asset is reported on Form 8621, the Form 8938 instructions may allow you not to duplicate the asset details, but the asset value can still count toward the Form 8938 threshold.
Possible exceptions to PFIC filing requirements
Possible exceptions can reduce Form 8621 Part I reporting, but they are not blanket exemptions. The $25,000 threshold, $50,000 joint threshold, and $5,000 indirect ownership threshold generally do not protect a taxpayer who has had an excess distribution, disposition gain, or PFIC election.
There are a few possible exceptions to standard PFIC filing requirements, but each one needs careful review.
The following 4 possible exceptions are commonly relevant for US expats with PFIC funds:
- Low-value exception: A shareholder may not need to complete Part I for a specific section 1291 fund if the shareholder’s aggregate PFIC stock value is $25,000 or less on the last day of the tax year. The threshold is $50,000 for joint filers. This possible exception does not apply if the shareholder receives an excess distribution from, or recognizes gain on the sale or disposition of, that section 1291 fund.
- Indirect PFIC value of $5,000 or less: A shareholder may not need to complete Part I for indirect ownership of a specific section 1291 fund if the shareholder’s proportionate share is $5,000 or less and there is no excess distribution or disposition gain.
- Certain treaty foreign pension funds: In certain situations, a member, beneficiary, or participant in an arrangement treated as a foreign pension fund under a US income tax treaty may not be required to complete Part I for PFIC stock held by that arrangement. This is highly fact-specific.
- CFC/PFIC overlap rule: If a foreign corporation is both a CFC and a PFIC, section 1297(d) may reduce or eliminate PFIC treatment for a US shareholder during the qualified portion of the holding period, but it is not a blanket rule that always replaces Form 8621 with Form 5471.
If a foreign corporation is both a CFC and a PFIC, the CFC/PFIC overlap rule may reduce or eliminate PFIC treatment for a US shareholder during the qualified portion of the holding period under section 1297(d). Whether Form 8621 is still needed depends on ownership structure, timing, and whether PFIC treatment applies outside the qualified period.
Do not assume a PFIC is exempt from Form 8621 just because it is held through a foreign pension. PFIC treatment for foreign pension arrangements is highly fact-specific, and the Form 8621 rules do not provide a general exemption for all foreign pensions or for UK SIPPs as such.
For CFC overlap questions, see our guide to Form 5471 reporting for foreign corporations.
PFIC tax strategies: how to avoid high taxes and reduce PFIC exposure
The strongest PFIC tax strategy starts before purchase and continues through each 2025 statement, election deadline, and sale decision. A US taxpayer can often reduce PFIC taxes by avoiding foreign pooled funds, making a timely QEF or MTM election, and fixing missed PFIC filing before selling.
Here are some strategies to help reduce the tax burden associated with PFICs:
The following 4 strategy windows can reduce PFIC tax implications without keyword stuffing or last-minute cleanup:
- Before buying: Confirm fund domicile, US tax entity classification, and whether a US-domiciled equivalent is available. A US mutual fund or ETF holding foreign assets is generally not a PFIC, while foreign mutual funds and non-US ETFs may be PFIC funds.
- While holding: Track acquisition dates, cost basis, distributions, year-end fair market value, foreign currency conversion, and prior elections. Good PFIC accounting is the difference between a manageable Form 8621 and a reconstruction project.
- Before selling: Review whether the gain would be treated as a section 1291 excess distribution and whether MTM or QEF is available before the sale year closes. Selling first and analyzing later can lock in avoidable PFIC taxes.
- If behind: Gather prior statements, identify each year a trigger applied, and consider whether a late or retroactive election may be available. Late PFIC filing should be coordinated with the broader return, FBAR, and FATCA position.
Make a timely QEF election when the fund provides the required statement. This can help you avoid the interest charge on excess distributions and may preserve capital-gain character for net capital gain.
Consider US-based mutual funds or ETFs. Investing through US-based funds, even if they hold foreign assets, is generally not subject to PFIC rules because the fund is a domestic entity.
Evaluate your holding period. Long holding periods can lead to substantial interest charges under section 1291, especially when no QEF or MTM election was made in the first PFIC year.
The 6 most common PFIC mistakes are preventable if the investor reviews the fund before the 2026 filing deadline.
The following 6 mistakes often create higher PFIC taxes or delayed filings:
- Assuming a foreign brokerage statement identifies every PFIC investment.
- Treating a foreign ETF as equivalent to a US ETF for US tax purposes.
- Ignoring PFIC mutual funds held inside a pension, ISA, SIPP, superannuation account, or insurance wrapper.
- Missing indirect PFIC reporting through a K-1, trust, or foreign pass-through entity.
- Making an MTM election without confirming the shares are marketable stock.
- Waiting until after sale to calculate section 1291 interest and basis adjustments.
PFIC tax rules are unforgiving because the default method becomes more expensive over time. A passive investment company label in a local brochure is not enough to determine US tax treatment, but it is a warning sign that the investment may need a PFIC review.
Do you need to report PFIC investments? Action checklist
Use this 6-step checklist before filing a 2025 return in 2026 if you own a foreign mutual fund, ETF, unit trust, REIT, insurance wrapper, or partnership-held foreign fund. The goal is to identify PFIC status, Form 8621 triggers, FBAR/FATCA overlap, and any available election before filing.
The following 6 actions help determine whether you have PFIC reporting requirements:
- Identify the fund domicile and legal form. Confirm whether the investment is organized outside the United States and treated as a foreign corporation for US tax purposes.
- Gather statements. Collect purchase confirmations, sale confirmations, distribution records, year-end values, and currency data for each PFIC investment.
- Check Form 8621 triggers. Review distributions, dispositions, QEF reporting, MTM reporting, elections, and annual reporting under section 1298(f).
- Check FBAR and FATCA. If the PFIC is held in a foreign account, check the $10,000 FBAR threshold and the applicable Form 8938 threshold.
- Choose an election if available. Review QEF first if the fund provides an annual statement, then MTM if the stock is marketable.
- File consistently. Prepare each required Form 8621 and align it with Form 1040, Form 8938, FBAR, Schedule B, foreign tax credit reporting, and any Form 5471 or K-1 information.

PFIC FAQ
A PFIC is a foreign corporation that meets either the 75% passive income test or the 50% passive asset test. PFICs are taxed differently because the PFIC regime is designed to prevent US taxpayers from deferring US tax through offshore passive foreign investment structures.
The PFIC definition focuses on the company’s income and assets each year, not the investor’s intent. A foreign investment company can be a passive foreign investment company even when the fund is ordinary and fully regulated in the country where the investor lives.
No. Form 8621 is generally required only when 1 filing trigger applies, such as a distribution, sale gain, QEF reporting, MTM reporting, another election, or annual reporting under section 1298(f).
PFIC filing requirements still need a careful threshold review. The $25,000 / $50,000 low-value rule does not override a PFIC excess distribution, disposition gain, or election.
PFICs are taxed under 3 main methods: section 1291 excess distribution, section 1296 mark-to-market, and section 1295 QEF. Each method changes how PFIC income, basis, gain, and losses are reported on Form 8621.
PFIC tax rules can produce ordinary income, interest charges, or annual inclusions even without a cash sale. This is why PFIC taxes should be reviewed before a fund is sold.
Common PFIC investments include foreign mutual funds, foreign ETFs, offshore investment trusts, unit trusts, and pooled foreign funds. Some foreign REITs, insurance wrappers, and pension-held funds can also meet the PFIC requirements depending on entity classification and treaty treatment.
A passive foreign investment corporation is not the legal phrase used in the Code, but taxpayers sometimes use it when referring to a passive foreign investment company. The correct term for Form 8621 purposes is passive foreign investment company.
Yes. A PFIC held in a foreign financial account can count toward the $10,000 FBAR threshold, and a PFIC can also be a specified foreign financial asset for Form 8938. These filings are separate from Form 8621.
Do PFICs go on FBAR/Form 8938? They can. FBAR focuses on foreign financial accounts, while Form 8938 covers specified foreign financial assets and may require identifying assets reported on Form 8621.
You may reduce PFIC taxes by avoiding foreign pooled funds when a US-domiciled alternative works, making a timely QEF election, using MTM when shares are marketable, or fixing missed PFIC filing before a sale. The best option depends on 2025 data and prior elections.
PFIC tax treatment should be modeled before the return is filed, especially when the holding period is longer than 3 years or the fund has large unrealized gains.
A foreign ETF is often a PFIC if it is organized as a foreign corporation and meets the 75% passive income or 50% passive asset test. A PFIC ETF can trigger Form 8621 even if it holds US stocks or reports cleanly in the local country.
The key distinction is domicile. A US-domiciled ETF holding foreign shares is generally not a passive foreign investment company, while a non-US ETF can fall into the passive foreign investment company PFIC rules.
A pension is not automatically a PFIC, but funds inside a foreign pension can create PFIC issues depending on the plan, treaty, ownership, and entity classification. Certain treaty foreign pension funds may qualify for limited exceptions to Part I reporting.
This is one of the most fact-specific PFIC requirements for expats. A passive foreign investment inside a UK SIPP, Australian superannuation account, or other foreign pension should be reviewed before assuming Form 8621 is not needed.
If you missed Form 8621 for a year when it was required, the IRS may keep the assessment period open under section 6501(c)(8) until the missing information is provided. Additional PFIC tax, interest, and other penalties can also apply if income was omitted or incorrectly reported.
A missed form does not always mean the same correction path. Prior-year PFIC reporting should be coordinated with the full return, Form 8938, FBAR, and any late election analysis.
A late QEF election may be possible only in limited situations, such as when the taxpayer preserved the right under the protective statement regime or obtains IRS consent under the consent regime. The Form 8621 instructions describe specific requirements for retroactive elections.
For most taxpayers, the cleanest QEF election is made by the due date, including extensions, for the first year the election applies. Late QEF analysis is a PFIC tax rules issue that should be handled before filing amended returns.
PFIC meaning is a US tax classification for a foreign corporation that meets the 75% income test or 50% asset test. A passive investment company is a general phrase and does not, by itself, determine US reporting.
A passive foreign investment corporation is also not the statutory term. The correct passive foreign investment company IRS term is used on Form 8621 and in sections 1291 through 1298.
For 2025 tax year returns filed in 2026, the main PFIC filing requirements are to identify each PFIC, determine whether a Form 8621 trigger applies, choose or maintain any valid election, and coordinate FBAR/Form 8938 if the asset is held in a foreign account.
The passive foreign investment company PFIC rules can also apply through indirect ownership. If a partnership, trust, estate, or foreign entity owns PFIC stock, the US taxpayer may still have PFIC reporting obligations.
