Why Swiss banks refuse Americans, and which don't

If a Swiss bank has ever ended a meeting the moment you showed your US passport, it isn't personal. It's the hangover from a decade-long fight between Washington and Swiss banking.

The short version

The trigger was UBS. In February 2009, UBS admitted helping Americans hide money, paid USD 780 million and agreed to hand over client names [1].
Then came the DOJ's Swiss Bank Program. Eighty Swiss banks signed non-prosecution agreements and paid more than USD 1.36 billion in penalties [2].
FATCA made Americans paperwork-heavy. Switzerland has run FATCA under a "Model 2" agreement since 2014. A new "Model 1" agreement was signed in 2024, but the Swiss government now says it will enter into force on January 1, 2029 at the earliest [3].
You can still bank here. Living in Switzerland with a Swiss address makes it much easier. Expect US-specific forms, fewer investment products, and some banks and apps that say no outright.
Uncle Sam still wants his reports. FBAR and Form 8938 apply to your Swiss accounts no matter which bank you use [4].

How Swiss banking got here: 2008 to 2016

For generations, Swiss bank secrecy was the stuff of spy movies. Then the US Justice Department came knocking.

Year	What happened
2009	UBS signs a deferred prosecution agreement, pays USD 780 million in fines, penalties, interest and restitution, hands over the identities of certain US customers and agrees to exit the business of serving US clients with undeclared accounts [1]
2013	Switzerland and the US sign a memorandum on interpreting the FATCA agreement [3]
2014	The Model 2 FATCA agreement enters into force on June 2 [3]
2015–2016	Under the DOJ's Swiss Bank Program, 80 "Category 2" banks sign non-prosecution agreements between March 2015 and January 2016, paying more than USD 1.36 billion in penalties [2]
2016	The DOJ announces the final resolutions under the program on December 29 [2]
2024	Switzerland and the US sign a Model 1 FATCA agreement on June 27 [3]

The lesson Swiss compliance departments took from all this was simple: American clients can cost a fortune if anything goes wrong. Many banks decided the safest US client was no US client, especially for wealth management. Even after the program wrapped up, the caution stuck.

FATCA in Switzerland: Model 2 now, Model 1 later

FATCA (the Foreign Account Tax Compliance Act) requires foreign banks to identify American account holders and report them to the IRS. Countries signed one of two kinds of agreements with the US Treasury:

Model 1: banks report to their own tax authority, which passes the data to the IRS. Exchanges usually run both ways.
Model 2: banks report directly to the IRS, with the client's consent. Accounts of clients who don't consent are reported in aggregate, and the IRS can follow up with group requests.

Switzerland has been a Model 2 country since June 2, 2014 [3]. PostFinance describes how this works in practice: a US person's account is treated as that of a "non-consenting client" unless the customer gives written consent for the data to go to the IRS, and the bank reports the number and total value of non-consenting accounts by the end of January each year [5]. A 2019 protocol to the US–Swiss tax treaty lets the US make group requests for such cases going back to June 30, 2014 [3].

What the switch to Model 1 means (and when)

Switzerland and the US signed a Model 1 agreement on June 27, 2024 [3]. Under it, Swiss banks will report through the Swiss tax authorities rather than straight to the IRS, and information will flow in both directions. You'll still see 2027 as the start date in older news stories, but the State Secretariat for International Finance's page, published June 29, 2026, says the "earliest entry into force is scheduled for 1 January 2029" and that implementation is still under way [3]. Special transitional rules are meant to bridge the two systems.

For a law-abiding American, the switch shouldn't change much day to day. Your bank already knows you're a US person and already asks for your consent and a US tax form. Model 1 mainly changes the pipe the data goes through.

What Swiss banks ask Americans for

When you open an account as a US citizen or green card holder, expect:

Your passport and Swiss residence permit, plus proof of your Zurich address.
IRS Form W-9 with your Social Security number, confirming you're a US person.
A FATCA consent or waiver allowing the bank to report your account to the IRS.
A self-certification of tax residence, often a combined FATCA and CRS form.
Sometimes proof that you're up to date with the IRS. Some banks ask; many don't.

The investment side is where Americans hit the most walls. Even banks that happily open a checking account for you may restrict or refuse securities accounts, because US securities law and US tax reporting make it complicated to sell Swiss funds to US persons. And for good reason from your side too: many Swiss and European funds are PFICs under US tax law, which are punishing to own.

Fees vary by bank and account package. We haven't found published, comparable fees for US-person accounts, so compare each bank's current price list and ask whether any US-specific charge applies before you sign.

Which banks take Americans, and which don't

Nobody publishes a neat list, and policies change, so treat this as a starting point and call before you go.

Bank or app	What we found	Source
PostFinance	Has a public service mandate and publishes how it handles US-person accounts and FATCA consent	Own FATCA page [5]; swissinfo (2018) [6]
Yuh	Says it will refuse to open your account if you're a US person	Own FAQ, updated June 2026 [7]
neon	Requires you to be tax resident "exclusively in Switzerland," which a US citizen arguably isn't, since the US taxes its citizens wherever they live	Own FAQ [8]
UBS, some cantonal banks, Valiant	Reported by American readers as opening accounts for US residents of Switzerland	The Local (2021, reader reports) [9]

A few practical notes:

PostFinance, the post office's bank, is the place many Americans start. Swissinfo noted in 2018 that its public service mandate covers all residents [6], though that article is old and the bank still decides case by case.
Big banks and cantonal banks often do open everyday accounts for US citizens who live in Switzerland. Reader reports from 2021 mention UBS and some cantonal banks, and say UBS required an in-person visit to sign the FATCA documents [9]. Those reports are old and not verified by the bank, so ask the branch directly.
Neobanks and app-based accounts are where Americans get turned away most often. Read the FAQ before you download the app.
Being resident matters. A US citizen living in Zurich with a residence permit and a Swiss employer is a much easier client than an American living in the US who wants a Swiss account.

Your US reporting obligations

Your Swiss bank reports you, and you report your Swiss accounts too:

FBAR (FinCEN Form 114): file it if your foreign accounts add up to more than USD 10,000 at any point in the year.
Form 8938: if you live abroad, file it with your Form 1040 when your foreign financial assets exceed USD 200,000 on the last day of the year or USD 300,000 at any time, or USD 400,000 and USD 600,000 for joint filers [4].
Joint accounts with a Swiss spouse count too, which can make the bank's FATCA paperwork awkward for your partner. Raise it with the bank before you open one.

A US expat tax preparer can check your situation, especially if you have old undeclared accounts to clean up.
