[LEGISLATION ALERT] Do You Really Need to File Form 8621 for Mark-to-Market PFICs Below the Reporting Threshold?

# [LEGISLATION ALERT] Do You Really Need to File Form 8621 for Mark-to-Market PFICs Below the Reporting Threshold?

If you're a US expat or digital nomad investing internationally, PFICs (Passive Foreign Investment Companies) are probably already on your radar. But the IRS rules around them? Those are considerably murkier—especially when you're dealing with mark-to-market elections and conflicting guidance on Form 8621 filing requirements.

What's Causing the Confusion?

A recent community discussion highlights a genuine pain point: Form 8621's filing requirements appear contradictory.

On one hand, the form explicitly states that any US Person with a section 1296 mark-to-market election must file Form 8621 each tax year. On the other hand, the form later references exceptions to filing Part I, which includes situations involving reporting thresholds.

So what happens when you've made a mark-to-market election, sold most of your PFIC holdings, but still have a small position left that falls below the reporting threshold? Do you file or not?

Why This Matters for Expats and Digital Nomads

The mark-to-market election under section 1296 is actually one of the more favorable PFIC treatment options available—it requires you to report gains annually at ordinary income rates rather than dealing with the complex "excess distribution" rules. However, favorable treatment comes with administrative burden, and filing requirements are a major part of that burden.

For expats managing multiple financial accounts across borders, clarity on compliance is non-negotiable. Filing unnecessarily creates extra work (and fees if you're using a tax professional), while *not* filing when required could trigger serious penalties.

The Actual Rule (As Best We Understand It)

Here's the key insight: the initial broad requirement and the exceptions must be read together.

The "exceptions to filing Part I" likely mean that while you must continue reporting the mark-to-market election itself (suggesting Form 8621 is technically due), certain sections of the form may not apply when holdings fall below reporting thresholds. This is IRS guidance's way of reducing administrative burden in lower-value situations.

In practical terms: If you have an active mark-to-market election, you likely still need to file Form 8621, but you may be able to skip certain parts or schedules if your remaining PFIC position falls below the threshold.

What You Should Do

1. Don't assume you're exempt: The presence of a mark-to-market election typically means Form 8621 filing obligations remain, regardless of current position size.

2. Review your specific facts: The threshold rules are nuanced and depend on the exact value, timing of sales, and current holdings. Your situation might legitimately qualify for an exception.

3. Work with a qualified professional: This is one of those tax gray areas where DIY filing creates real risk. A tax professional specializing in international or expat taxation can clarify your specific obligations based on the exact wording of current IRS guidance.

4. Keep records: Document your mark-to-market elections and the reasoning for any decision not to file. This creates a defensible position if the IRS asks questions later.

The PFIC rules are notoriously complex, and the IRS knows it. But that complexity doesn't excuse non-compliance—it just means you need expert help to get it right.
