Swiss Bank Account for US Citizens: 4 Options (2026)
For US persons living in Switzerland, PostFinance and UBS are the most straightforward everyday accounts in 2026: both charge no US-person surcharge, have established FATCA processes for US clients, and offer fully English apps and e-banking. ZKB also serves US clients living in Switzerland but tacks on CHF 360 per year. Migros Bank opens accounts in branch according to user reports, although it doesn’t say so officially.

What is a US Person?
According to US tax law, US persons include not only US citizens but also, for example, Green Card holders. Swiss citizens who were born and raised in Switzerland can also be US persons if they also hold US citizenship. This can happen through birth in the USA or, if certain requirements are met, through American parents. What counts is citizenship, not whether you hold a valid US passport.
This article focuses exclusively on US persons who live in Switzerland and want to open a bank account here. Many Swiss banks are hesitant to maintain accounts for US persons, and for good reason.
FATCA and Worldwide US Taxation
The reason for many Swiss banks’ reluctance lies in the Foreign Account Tax Compliance Act (FATCA). This US law, introduced in 2010, requires foreign financial institutions to report accounts of US persons to the IRS. Switzerland currently uses Model 2: banks report directly to the IRS with the client’s consent. Without consent, they report the accounts in aggregated form, and the IRS can request the details through group requests under administrative assistance (FTA). For Swiss banks, that means considerable administrative effort.
The USA is one of the few countries worldwide that taxes its citizens even when they live abroad and already pay taxes there. This worldwide tax obligation applies regardless of where the income is earned. Whether you have to file a US return depends on your income, filing status and age (IRS). Living in Switzerland doesn’t remove that obligation, even after decades. Many smaller banks and financial service providers therefore simply opt out of taking US persons as customers, Yuh for example.
Important: As soon as you’re a US citizen, you must disclose this when opening an account, regardless of whether you also hold another citizenship (SwissBanking). The bank then reports your account to the US tax authority under the FATCA rules.
What Documents Do US Persons Need to Open an Account?
All four banks usually ask for:
- Passport or Swiss ID
- Swiss residence permit or proof of address
- US taxpayer identification number (TIN, usually your SSN)
- The bank’s FATCA self-certification
- Form W-9 for US persons
ZKB explicitly lists the self-certification and the W-9. For larger deposits or planned investments, banks also ask about the source of funds. Plan about an hour for the branch appointment and bring originals of every document.
PostFinance
PostFinance holds accounts for US clients, including dual citizens, and its FATCA page explains how it reports their data to the IRS with written consent. According to its price list, it charges no additional fees for US persons. This makes it the most attractive option for everyday banking.
The relevant banking packages are:
- Smart for CHF 5 per month: personal account, savings account, and debit card (PostFinance Card)
- SmartPlus for CHF 10 per month: additionally a free Classic/Standard credit card or the Mastercard Value prepaid card
You get a CHF 5 per month discount with invested assets of CHF 25,000 or more at PostFinance, or with a PostFinance mortgage or life insurance. Balances in personal and savings accounts don’t count. For US persons, the investment route is closed: according to PostFinance, all its investment services and financial instruments are unavailable to US persons. So expect to pay CHF 5 per month for Smart.
As a US person, you have to visit a branch in person to open the account. The PostFinance app and e-finance are fully available in English.
UBS
UBS also has established FATCA processes for US clients, including self-certification. According to its price list, it charges no additional fees for US persons. As the only major Swiss bank, it also has a direct presence in the USA through UBS Bank USA. That is rarely relevant in daily life, but it’s practical if you manage assets on both sides and want one bank with a footprint in both countries.
The basic offer is UBS Banking Easy: CHF 0 per month from age 26, with a personal account, savings account, and debit card, provided you receive account documents electronically. Credit cards come with the paid packages, such as Classic for CHF 8 per month if you held at least CHF 10,000 in assets at UBS throughout the previous month or have a UBS mortgage, otherwise CHF 13.
Account opening must be done in person at a branch. English-language support is excellent. Both the mobile app and e-banking are fully available in English.
Zürcher Kantonalbank (ZKB)
ZKB’s price list explicitly covers “US clients domiciled in Switzerland” (“US-Kunden mit Domizil Schweiz”). However, it charges them an “international base fee” (“Basisgebühr International”) of CHF 90 per quarter, or CHF 360 per year. The fee is charged per client, on top of the prices for individual products. Clients domiciled abroad pay the same fee.
This is particularly annoying because the regular ZKB Banking package otherwise costs CHF 0: up to 3 personal accounts, a savings account, and up to 2 Visa debit cards. As a US person, you’re paying CHF 360 a year for a package that Swiss residents without US ties get for free.
There are exceptions: customers with an existing mortgage or loan at ZKB are exempt. So if you’re planning to finance a property through ZKB, this becomes a viable option. Another catch: account opening is only available at ZKB’s headquarters in Zurich at Bahnhofstrasse 9, not at regular branches.
Where ZKB does excel is in English-language documentation. It offers the most comprehensive collection of legal documents in English: the General Conditions and the Conditions for Payment Services are available as English PDFs. In e-banking and mobile banking, you can switch between German and English. For anyone who values legal clarity in English, ZKB is the best choice.
Migros Bank
Migros Bank makes no official statement about accepting US persons. According to multiple user reports, US persons with Swiss residency have been able to open accounts there, and no additional fees have been reported.
The standard offer is solid: free account management including a Visa debit card, and an optional savings account with free account management.
Account opening must also be done in person here. The biggest drawback for English speakers: e-banking and mobile banking are only available in German, French and Italian, not English.
For US persons who speak German fluently and are already Migros customers, Migros Bank can be a practical solution. For everyone else, there are better options.
New FATCA Agreement: What Changes from 2029 at the Earliest?
Switzerland and the USA signed a new FATCA agreement under Model 1 on 27 June 2024. According to the State Secretariat for International Finance (SIF), the earliest entry into force is 1 January 2029, and implementation is still under way. Until then, the current Model 2 applies.
Under Model 1, Swiss banks will no longer report US-person data directly to the IRS. Instead, they’ll send it to the Swiss Federal Tax Administration (FTA), which exchanges the information automatically with the US. In return, Switzerland will receive information on US accounts held by Swiss residents.
For you as an account holder, the basic rule stays the same: you declare your US status to the bank, and information on your reportable accounts still ends up with the IRS. What changes is that reporting runs automatically through the FTA instead of directly from the bank with your consent. Besides Form W-9, the agreement also allows a similar agreed form (agreement text, Annex I, German). What could change is the willingness of smaller banks: with a clearer reporting path through the FTA, more Swiss institutions may start onboarding US persons afterwards.
Conclusion
As a US person in Switzerland, you definitely have options for a bank account, even if the selection is more limited than for other residents. My recommendation:
PostFinance is the best choice for most US persons. No additional fees, solid account models, and good English support make it the most straightforward option. Expect CHF 5 per month, since the investment-based discount isn’t available to US persons.
UBS is a good alternative, especially if you manage assets in both the USA and Switzerland or are already a customer.
ZKB is only worthwhile if you’re exempt from the fee (e.g. through a mortgage or loan) or if English-language documentation is particularly important to you.
Migros Bank is an option for German-speaking US persons, but e-banking and the app aren’t available in English.
Frequently Asked Questions
Can a US citizen open a bank account in Switzerland?
Yes. PostFinance, UBS, and ZKB accept US persons with Swiss residency. Opening is always done in branch; you’ll need a passport, residence permit, your US tax ID (TIN, usually your SSN), and a signed Form W-9.
Which Swiss banks accept US persons?
Confirmed: PostFinance, UBS, and ZKB. ZKB charges CHF 90 per quarter for it. Migros Bank also lets US persons open accounts based on user reports, but doesn’t say so officially. Many other cantonal banks and neobanks such as Yuh either decline US persons or review them only on a case-by-case basis.
Do I have to disclose US citizenship if I’m also Swiss?
Yes. FATCA doesn’t care about your country of residence or your primary citizenship: it tracks US status. Dual citizens with US citizenship must declare it when opening an account. The bank then reports the account to the IRS, directly with your consent or otherwise in aggregated form, regardless of how long you’ve lived in Switzerland.
Can a US person open a Swiss account online?
Not at any of the four banks compared here. All require in-person identification at a branch, because FATCA forms must additionally be signed and certified.
What happens if I don’t submit FATCA forms?
If you don’t consent to reporting to the IRS, your account is treated as “non-consenting”. The bank then reports it to the IRS in aggregated form, and the IRS can request the details through a group request under administrative assistance (FTA). Banks can also end such relationships: ZKB states that it terminates relationships with non-consenting clients. In practice, most Swiss banks simply refuse to open the account if FATCA documents are missing.
Which bank is cheapest for US persons in Switzerland?
Going by the price lists, UBS Banking Easy is the cheapest at CHF 0 per month. PostFinance Smart costs CHF 5 per month. You can’t use the discount for CHF 25,000 in invested assets as a US person, because PostFinance doesn’t offer investment services to US persons. At ZKB, the package costs CHF 0, but the CHF 360 annual base fee comes on top unless you have a mortgage or loan with ZKB.
