Zurich has one of the largest American communities in Switzerland, concentrated in finance, insurance, tech and consulting. Many arrive on local or expat contracts, open accounts with banks like UBS or ZKB, and start investing — often without realizing how U.S. reporting follows them across the Atlantic.

Typical situations we see in Zurich

Finance and tech professionals with RSUs, bonuses and Swiss salary to reconcile on a U.S. return.
Swiss or European ETFs and funds bought through a local broker that may be PFICs.
Multiple bank and brokerage accounts that together cross the FBAR threshold.
Recent arrivals who haven't yet filed a U.S. return from Switzerland.

U.S. tax filing does not disappear when you move to Zurich. Swiss salary, bank accounts and investments can create U.S. reporting obligations — even when no U.S. tax is owed.

What to check first

Start with whether your combined non-U.S. accounts crossed $10,000 at any point (FBAR), whether you hold non-U.S. funds (PFIC), and whether any prior years are outstanding. The free Tax Risk Check walks you through it in a couple of minutes.

Frequently asked questions

I work in finance in Zurich with RSUs — is that complicated for U.S. taxes?

RSUs and bonuses are reportable, and the interaction with Swiss tax and the Foreign Tax Credit is worth getting right — equity compensation adds steps but is manageable. Atamatax provides preparation support; this is not individualized advice.

Do Americans in Zurich still need to file U.S. taxes?

In most cases yes — the U.S. taxes citizens and Green Card holders on worldwide income regardless of residence. Credits and exclusions often reduce the U.S. tax owed, but reporting (including the FBAR) can still be required.

Does Atamatax work with people based in Zurich?

Yes. Atamatax provides fixed-fee U.S. tax filing support for U.S. persons across Switzerland, including Zurich. The final quote depends on your documents and tax situation.
