Form 8621 (PFIC) Filing Requirements – Avoid Costly Errors

By /
Form 8621 PFIC Filing Requirements - if you meet the rules for filing then you need to file the form.

Form 8621, Information Return by a Shareholder of a Passive Foreign Investment Company (PFIC), is used to report ownership in a foreign corporation that meets the PFIC tests and to calculate related U.S. tax. Find out more on Form 8621 PFIC Filing Requirements

What is a PFIC?

A foreign corporation is a PFIC if it meets either test in a tax year, then it may trigger Form 8621 PFIC Filing Requirements:

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

Who MUST file Form 8621

You must file Form 8621 if any of the following apply:

  1. You received a PFIC distribution
  • Including excess distributions or gain from disposition of PFIC stock
  • You recognize PFIC income
  • Income under:
    • §1291 (default excess distribution rules)
    • §1293 (QEF inclusion)
    • §1296 (Mark-to-Market election)
  • You are making or maintaining a PFIC election
  • QEF election
  • Mark-to-Market election
  • Purging election
  • Election to recognize gain on deemed sale
  • You are reporting annual information as a PFIC shareholder
  • Even with no distributions, if an election applies

Exception – when Form 8621 is NOT required

You do not have to file Form 8621 solely due to ownership if all the following are true:

  • No excess distributions
  • No gain or loss recognized
  • No PFIC election made or in effect
  • PFIC stock value is below the filing threshold

PFIC reporting thresholds (per taxpayer)

  • $25,000 or less at year-end
  • $50,000 or less if married filing jointly

If these thresholds are exceeded, Form 8621 is required even with no income.

Common investments that trigger Form 8621

  • Foreign mutual funds & ETFs
  • Non-U.S. money market funds
  • Foreign pooled investment funds
  • Certain foreign retirement funds (non-treaty protected)

Penalties & compliance notes

  • No specific dollar penalty, but statute of limitations stays open indefinitely if Form 8621 is required and not filed
  • Often reviewed in FBAR / FATCA audits

PFIC reporting is required by law

If you are a U.S. taxpayer who owns shares in a Passive Foreign Investment Company (PFIC)—such as:

  • Foreign mutual funds or ETFs
  • Non-U.S. investment funds
  • Some foreign pension or insurance wrappers

you likely meet the Form 8621 PFIC Filing Requirements for each PFIC, every year, unless a narrow exception applies.

Failure to file = noncompliance, even if:

  • You had no income
  • The account value is small
  • You already reported the account on FBAR or Form 8938

Avoid the harsh default PFIC tax regime

If you don’t file PFIC forms, the IRS automatically applies the default “excess distribution” regime, which:

  • Retroactively taxes income over multiple years
  • Applies the highest marginal tax rate for each year
  • Adds interest charges as if you underpaid tax for years

This often results in confiscatory-level taxation.

👉 Filing Form 8621 allows you to:

  • Make a QEF election or Mark-to-Market election
  • Convert punitive taxation into annual, predictable taxation
  • Prevent compounding interest charges

This could be a costly error of not complying with the form 8621 PFIC filing requirements.

Keep the statute of limitations open (or closed)

This is one of the most overlooked reasons.

If PFIC forms are not filed:

  • The entire tax return remains open indefinitely
  • The IRS can audit all items on the return—forever

When PFIC forms are properly filed:

  • The statute of limitations starts running normally (generally 3 years)
  • You regain finality and audit protection

Prevent downstream penalties and compliance cascades

Not complying with the Form 8621 PFIC filing requirements often trigger:

  • IRS notices years later
  • Forced amended returns
  • Large professional fees to reconstruct historical data
  • Secondary penalties tied to “incomplete returns”

Once the IRS identifies a PFIC issue, it frequently expands into:

  • Foreign asset reporting reviews
  • Prior-year compliance checks
  • Examination of other international forms

Required even when there is no tax due

Many taxpayers assume the is no Form 8621 PFIC filing requirement:

“If there’s no income, I don’t need to file.”

That is incorrect for PFICs.

Form 8621 is required even when:

  • No distributions were received
  • The fund lost money
  • The investment is small
  • The account was held briefly

The form is about information reporting and elections, not just tax.

Essential for future planning and exit strategies

PFIC forms matter long-term, especially if you plan to:

  • Sell the investment
  • Restructure foreign holdings
  • Claim treaty positions
  • Renounce U.S. citizenship

Without properly filed PFIC forms:

  • Exit taxes can balloon unexpectedly
  • Historical elections may be unavailable
  • Clean expatriation becomes much harder

Even though there is no monetary penalty (currently) for not complying with the form 8621 PFIC filing requirements, it can be an expensive error in many other ways as outlined above.
