Geneva is home to a large U.S. and dual-national community, many working for the UN and its agencies, NGOs, private banks and multinationals. International-organization employment brings its own U.S. tax nuances, alongside the usual Swiss salary, account and investment questions.

Typical situations we see in Geneva

Staff of international organizations and NGOs with specific U.S. tax treatment of their compensation.
Dual Swiss-U.S. citizens who have lived in Geneva for years and are catching up on U.S. filings.
Private-bank clients with Swiss investment accounts and funds that raise PFIC questions.
Cross-border workers and households with non-U.S. spouses.

Built specifically for U.S. persons living in Switzerland — including the international-organization and NGO community in Geneva.

International organization employees

If you work for an international organization, the U.S. treatment of your salary and any self-employment can differ from a standard Swiss employer. It's worth reviewing before filing rather than guessing.

Frequently asked questions

I work for a UN agency in Geneva — does that change my U.S. taxes?

Yes, it can. International-organization compensation has specific U.S. tax rules, and self-employment status sometimes applies. Atamatax can help you prepare; for a position that turns on your facts, a professional review is recommended.

Do Americans in Geneva 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 Geneva?

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