Zug — "Crypto Valley" — concentrates founders, crypto and blockchain professionals, commodities traders and holding companies, drawn partly by the canton's tax environment. These are often exactly the higher-complexity profiles for U.S. tax: entities, crypto and investments.

Typical situations we see in Zug

Founders and operators who own or control a Swiss company or foreign entity.
Crypto holdings and activity that are U.S.-reportable.
Investment portfolios with non-U.S. funds (PFIC considerations).
Prior years to clean up after a fast-moving move to Switzerland.

Foreign entities, crypto and non-U.S. funds combined often call for specialized handling before filing.

Frequently asked questions

I hold crypto and run a company in Zug — is that a complex U.S. case?

Yes — foreign entity ownership plus crypto and investments is among the more complex U.S. profiles and benefits from careful, specialized preparation. Atamatax can help you prepare; this is not legal or tax advice.

Do Americans in Zug 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 Zug?

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