The short answer for 2026
In 2026, PostFinance and UBS are the cleanest everyday options for US citizens in Switzerland: both accept US clients and charge no US-person surcharge. Zürcher Kantonalbank (ZKB) also accepts US clients but adds a CHF 90 quarterly "international base fee" — CHF 360 a year. Migros Bank reportedly opens accounts for US clients in branch, and Swissquote serves US persons who want to invest. The bigger issue is rarely finding a bank; it is the FATCA paperwork and US-side reporting costs that sit on top of the normal fees.
The 2026 starting list: who still says yes
- UBS: accepts US clients with no US-person surcharge. The UBS "Banking Easy" package is CHF 0 per month from age 26 (with electronic documents) and includes a personal account, savings account and debit card. Private banking relationships may require CHF 500,000 or more, and FATCA self-certification is mandatory.
- PostFinance: accepts US clients, including dual citizens, with no US-person surcharge per its price list. The "Smart" package is CHF 5 per month (personal account, savings account, debit card) and the app is fully in English. Investment services remain closed to US persons.
- Zürcher Kantonalbank: accepts US clients domiciled in Switzerland but charges CHF 90 per quarter (CHF 360 per year) as an "international base fee." Clients with a ZKB mortgage, loan or 3a account are exempt. Account opening is only at the Zurich headquarters (Bahnhofstrasse 9).
- Migros Bank: reportedly opens accounts for US clients in branch — not stated officially — with no US-person surcharge and a CHF 0 monthly fee. Support is in German, French and Italian only.
- Swissquote: accepts US clients for investing with a 0.15% annual custody fee on assets, but check whether US-domiciled securities or funds create PFIC issues before you buy.
The hidden math: your real cost is not the advertised fee
For a plain payment account, the US-person surcharge that once made headlines has largely disappeared at the big banks — PostFinance and UBS charge none, and Migros Bank reports none. Where costs still pile up is investment custody (0.1% to 0.5% of assets a year) and US tax reporting. FBAR and Form 8938 preparation typically costs $500 to $2,000 a year in preparer fees, and private banks may still bundle a CHF 1,000 to CHF 3,000 US-person surcharge into a wealth-management relationship. A basic bank-plus-brokerage setup can realistically run $2,000 to $8,000 a year once tax prep and custody are included.

What the fees actually look like
ZKB's CHF 90 quarterly fee is the exception, not the rule, at the mainstream banks in 2026. Ask any bank for its total US-person cost in writing — including execution-only and custody fees — before you open, and price your FBAR/Form 8938 preparation at the same time.
Account opening: what to expect as a US person
Every bank will confirm your US tax status and most require a FATCA waiver or W-9 before opening. UBS and PostFinance have established FATCA processes; larger cantonal banks such as ZKB and BCV accept US persons within their canton, while smaller ones often decline at the first mention of US citizenship. The practical move is to call, say you are a US citizen, and ask for the US-person fee in writing before opening — some published fee sheets do not show it. The U.S. Embassy in Bern publishes a banking-resources page listing banks that have indicated they serve US citizens, which is a useful cross-check. If you plan to pair the account with investing, which US brokerages still accept Americans living in Switzerland in 2026 is the natural next question.
Wise and Revolut for daily spending: a layer, not a replacement
Many Americans in Switzerland keep a Swiss account for salary and rent, then use Wise or Revolut for daily card spending and currency conversion. This does not remove FATCA or FBAR obligations — reportable accounts still need to be reported — but it can help you avoid paying Swiss private-bank custody fees on money you only spend, not invest. Treat these as a spending layer; if your employer or landlord requires a Swiss IBAN, they usually cannot replace a Swiss bank account.
What actually drives the cost difference
Banks handle FATCA differently. PostFinance and UBS fold the compliance work into general pricing and charge no US-person surcharge. ZKB passes it through as a visible CHF 90 quarterly fee, and Berner Kantonalbank charges US clients a CHF 20 monthly fee for the added regulatory burden. Private banks may quote a bundled surcharge of CHF 1,000 to CHF 3,000. If you are self-employed or own a Swiss company, US-side reporting expands quickly — have the bank-fee conversation together with your US tax preparer.
Cantonal banks and neobanks: patchy acceptance
Outside the main names, acceptance is inconsistent. Some larger cantonal banks will serve US clients within their home canton; smaller ones often decline because the compliance cost exceeds the revenue. Swiss neobanks like Neon and Yuh generally do not onboard US citizens, and Revolut's Swiss entity is not a guarantee of US acceptance. If a smaller bank accepts you, expect personal contact rather than purely digital onboarding. Note that this cuts both ways: Swiss banks are also reporting more US account information to the IRS, so which bank you choose matters for compliance, not just cost.
Your next step before opening or switching
The right Swiss bank depends on your US tax filing position, whether you invest, your residency status and your employer's payroll requirements. A basic Swiss payment account plus a US brokerage can keep the all-in cost lower than a full-service private bank, but only after a personal review of your situation. If UBS is on your shortlist, its full-service banking push for Americans in Switzerland is worth reading, and the postponed FATCA Model 1 switch to 2028 explains the reporting backdrop.
