Swiss Pillar 2 (BVG/LPP) & U.S. tax

The Swiss 2nd pillar (occupational pension, BVG/LPP) is mandatory for most employees. Its U.S. tax treatment is one of the more genuinely unsettled areas for Americans in Switzerland — so this page separates what's clearer from what's contested.
Reporting (clearer)
- A 2nd-pillar account is generally a reportable foreign account — on the FBAR if your combined non-U.S. accounts exceed $10,000 at any point.
- And on Form 8938 if you cross the higher abroad thresholds ($200,000 / $300,000 single; $400,000 / $600,000 married filing jointly).
U.S. taxation of the 2nd pillar (contested)
How the U.S. taxes 2nd-pillar contributions and in-plan growth is debated and fact-specific. Commentary ranges from treating it like a foreign pension or trust to other positions, and the U.S.–Switzerland treaty interacts here. This is not settled by a single IRS ruling, and it's an area to get a professional opinion on rather than assume.
The PFIC angle
Unlike a fund-based 3a, a standard 2nd pillar is typically a defined arrangement rather than you holding named funds — so it usually isn't a per-fund PFIC problem the way an invested 3a is. Confirm how your specific plan is structured.
Start with what you have to report
Check whether your 2nd-pillar and other accounts cross the FBAR and Form 8938 thresholds. Atamatax is tax-preparation software, not a CPA firm, and this is not individualised tax advice.
