Opening a US LLC's Business Bank Account in Switzerland: The 2026 Reality
The Swiss banking story for US-owned entities has changed twice in the last decade. Post-FATCA, the major retail-corporate banks (UBS, PostFinance, Raiffeisen) effectively stopped onboarding non-resident US-owned LLCs. Post-Credit-Suisse, the surviving private banks tightened minimums to CHF 1M to CHF 5M in assets under management. The middle ground — a working CHF business account for a non-resident US LLC with normal trading volumes — exists, but the door is narrow.
Who actually opens these accounts today
Three categories of bank still accept non-resident US LLC clients in 2026: (1) Cantonal banks in cantons running active foreign-investor programmes (Zug, Schwyz, Geneva), (2) Specialist trade-finance banks (Bank Frick in Liechtenstein technically, but they passport into CH; Hyposwiss before its retreat), and (3) EMI-style providers (Dukascopy, Yapeal, Relai for crypto-adjacent businesses). Each has different KYC tolerance and pricing.
The Zug playbook
Zug's Kantonalbank (ZKB) and several local cantonal partners actively court foreign-owned holding companies because of the canton's dependence on the corporate-tax base. A US LLC with a Swiss-resident introducer (a fiduciary, lawyer, or accountant licensed in Zug) can complete KYC in 6 to 10 weeks. The introducer fee is typically CHF 3,000 to 8,000 one-off, plus 0.1–0.3% of account turnover annually. The bank wants to see real business — invoices, contracts, a website, a US tax return.
What the bank actually asks for
Why founders attempt this anyway
Three reasons drive the effort: (1) CHF invoicing for European industrial customers who simply will not pay in USD or EUR, (2) hedging against US-dollar volatility for businesses with sticky CHF cost bases (machine tools, watch components, life sciences reagents), (3) credibility — a Swiss IBAN signals permanence in a way a Wise account does not, especially for B2B procurement in the DACH region.
The realistic alternative
If you cannot justify the CHF account economics, a multi-currency EMI account (Wise Business, Airwallex, Revolut Business) supports CHF receivables with a Swiss-domiciled IBAN issued through a partner bank. The IBAN looks Swiss but settlement happens through a correspondent network. For 80% of US LLCs invoicing Swiss customers under CHF 500k/year, this is the correct answer.
FATCA, CRS and what the bank reports about you
Every Swiss bank that opens an account for a US-owned LLC files an annual FATCA report with the IRS via the Swiss Federal Tax Administration. The report covers account balance, gross interest, gross dividends, and gross proceeds. It is not optional and not negotiable. Founders who set up a Swiss account hoping for opacity are 15 years out of date — Switzerland's 2014 FATCA Model 2 agreement and 2017 CRS adoption ended that era. The reason to open a Swiss account today is operational (CHF settlement, supplier credibility), not confidentiality.
