Pillar 3a & vested benefits
The Swiss deferral doesn't carry over, and the funds inside (Swisscanto, UBS, finpension lines) are almost always PFICs. We classify each holding and let you elect QEF/MtM/§1291 where applicable.
Convention 1996 · IRS × ESTV
Your Pillar 3a isn't tax-deferred to the IRS.
We classify every Swiss fund and reconcile your 1040 against the Steuererklärung.
Switzerland-US Convention 1996 covers dividends, interest, pensions, and capital gains. Pillar 3a wrappers and Swiss-domiciled funds get explicit attention because Swiss tax deferral doesn't carry over — and the 35% anticipatory tax is only partly creditable.

What we handle for Switzerland residents
The three things that bite Switzerland-based US citizens.
35% Verrechnungssteuer
Only the 15% treaty rate on dividends is creditable on Form 1116 — the other 20% is a refund you reclaim from the ESTV. We compute the credit at the treaty rate and flag the reclaim.
Federal + cantonal + communal credit
The full Swiss income-tax stack rolls into Form 1116 per category; Article 23 relief and Article 18 pension positions are flagged for Form 8833 only when you override the default.

Same workflow, different bilateral convention.
Switzerland treaty · FAQ
What US citizens in Switzerland ask us most.
- I already pay Swiss federal, cantonal, and communal tax — do I still owe the IRS?
- Usually not. The Switzerland-US Convention (1996) lets you credit the full Swiss income-tax stack on Form 1116, which zeroes out the US liability in most cases. But you still have to file the return and the credit forms — and the paperwork penalties attach even when $0 is owed.
- Is my Pillar 3a tax-free to the IRS?
- No. The IRS doesn't recognize Pillar 3a's Swiss tax deferral, and the funds inside — Swisscanto, UBS, finpension or frankly lines — are almost always Swiss- or Irish-domiciled funds the IRS treats as PFICs under §1297(a). We classify each holding and prepare a Form 8621 worksheet per fund.
- Can I credit the 35% Swiss withholding on my dividends?
- Only partly. Under Article 10 the treaty rate for US residents is 15%, so only that slice is creditable on Form 1116 — the remaining 20% of the Verrechnungssteuer is a refund you reclaim from the ESTV, not a credit. We compute the credit at the treaty rate and flag the reclaim so nothing is left on the table.
