Form 8621 Demystified: How Indians on H-1B Can Stay IRS-Compliant
For an H-1B professional, “Form 8621” is often a term discovered only after a tax preparer flags a “Passive Foreign Investment Company” (PFIC) in their Indian portfolio. In the 2026 tax cycle, as the IRS utilizes advanced AI to cross-reference FATCA data from Indian banks, filing this form correctly is no longer optional, it is a critical step in protecting both your wealth and your U.S. immigration status.
Who Must File Form 8621 in 2026?
As a resident alien under the Substantial Presence Test, you must file Form 8621 for the 2025 tax year if you meet any of these criteria:
- Direct Ownership: You hold units in an Indian Mutual Fund, ETF, or certain Unit Linked Insurance Plans (ULIPs).
- The $25,000 Threshold: Your total PFIC holdings (aggregate of all funds) exceeded $25,000 (Single) or $50,000 (Married Filing Jointly) on December 31, 2025.
- The “Any Amount” Rule: Regardless of the threshold, if you sold a fund or received a distribution (even a reinvested dividend) in 2025, you must file.
New for 2026: The “Three-Letter Currency Code”
The IRS recently updated the instructions for the December 2025 revision of Form 8621. This is a common trap for DIY filers:
- Part V Requirement: Filers are now explicitly required to enter the three-letter currency code (INR) in the entry space provided above Line 15a.
- USD Conversion: You must report the final amounts in U.S. Dollars, but the new form tracks the original currency to better sync with foreign bank data shared via FATCA.
Choosing Your Election: MTM vs. Section 1291
Your tax bill is determined by the “election” you make on Form 8621. For most H-1B holders, the choice is clear:
| Election Type | How it Works | Pros/Cons |
| Mark-to-Market (MTM) | Taxed on “paper gains” annually as ordinary income. | Pros: No interest penalties. Cons: You pay tax even if you don’t sell. |
| Section 1291 (Default) | Taxed only when you sell or get “excess” distributions. | Pros: No annual tax. Cons: 37% tax rate + compounded daily interest on gains. |
Strategic Advice: If 2025 was your first year as a U.S. tax resident, making the MTM Election on your first return is the most effective way to “lock in” your arrival-date basis and avoid decades of interest penalties.
Why “I Didn’t Know” is a Risky Defense
For H-1B holders, tax compliance is often viewed through the lens of “Good Moral Character” during Green Card (I-485) or Citizenship applications.
- Indefinite Audit Window: If you miss Form 8621, the statute of limitations for your entire 1040 return stays open forever.
- FATCA Matching: If you report your Indian accounts on the FBAR (FinCEN 114) but fail to attach Form 8621 to your 1040, the IRS’s automated “mismatch” filters may trigger an audit notice.

Frequently Asked Questions (FAQ)
Q: Does my Indian Employer Provident Fund (EPF) require Form 8621? A: Generally, no. Under Article 20 of the U.S.-India Tax Treaty, recognized pension funds are usually exempt from PFIC rules, though they must still be disclosed on FBAR/FATCA forms.
Q: Can I file one Form 8621 for all my mutual funds? A: No. The IRS requires a separate Form 8621 for each individual PFIC (fund) you own.
Q: What is the current IRS interest rate for PFIC look-backs? A: As of early 2026, the underpayment interest rate is 7% per year, compounded daily, making the “Default Method” more expensive than ever.
