What Swiss banks actually require from foreign customers

Swiss banks will open accounts for non-residents, but the process is slower and more document-heavy than opening one in your home country. You will need to provide proof of identity, proof of address, proof of income or wealth source, and often a reason for banking in Switzerland. Most banks require a minimum deposit that ranges from 250,000 to 1 million Swiss francs (CHF), though some private banks set higher thresholds.

The key difference from domestic accounts: Swiss banks now conduct extensive due diligence on foreign clients because of international tax reporting agreements. The U.S. Foreign Account Tax Compliance Act (FATCA) and the Common Reporting Standard (CRS) mean Swiss banks must verify your tax residency and report account information to your home country's tax authority. This is not optional for the bank, and it is not a barrier to opening an account—it is straightforward part of the process.

You cannot open a Swiss bank account online from abroad. You will need to visit a branch in person, work with a Swiss financial advisor who can represent you, or use a bank that has offices in your home country and can process the process there. The timeline from first contact to account opening typically runs four to twelve weeks.

Key Takeaways

  • Swiss banks require proof of identity, address, income source, and often a statement of purpose, plus a minimum deposit ranging from 250,000 to 1 million CHF depending on the bank.
  • You must visit a Swiss branch in person, work through a Swiss financial advisor, or use a bank with offices in your home country—online-only applications from abroad are not available.
  • Swiss banks report all foreign account information to your home country's tax authority under FATCA and CRS agreements, so tax compliance is built into the process.
  • The process takes four to twelve weeks from submission to account opening, and the bank will contact your employer or references to verify your income and background.

Documents you will need to gather before contacting a bank

Start by collecting a current passport or national ID card, a recent utility bill or rental agreement showing your current address, and documentation of your income or wealth. For income, this means recent tax returns (usually the last two years), payslips, or an employment letter on company letterhead stating your position and salary. For wealth, you may provide bank statements, investment statements, or property deeds.

You will also need to identify the source of the funds you plan to deposit. Swiss banks ask this not to judge you, but because international anti-money-laundering rules require them to know where money comes from. If you are depositing inheritance, bring the will or probate documents. If it is from a business sale, bring the purchase agreement or closing statement. If it is from employment or investments, the documents above will suffice.

Prepare a brief written statement of why you want to bank in Switzerland. This is not a formal essay—a paragraph explaining that you work internationally, have Swiss business interests, or manage assets across multiple countries is sufficient. Banks use this to understand your banking needs and confirm that the account makes sense for your situation.

Which Swiss banks accept non-resident accounts and what they require

The major banks—UBS, Credit Suisse, and Julius Baer—all open accounts for non-residents, but each has different minimum deposit requirements and service models. UBS typically requires 2 million CHF or more for wealth management services, though some of their standard accounts have lower minimums. Credit Suisse's minimums vary by account type, ranging from 250,000 CHF upward. Julius Baer focuses on private banking and generally requires 1 million CHF or more.

Smaller regional banks and cantonal banks may have lower minimums and less stringent requirements, but they are less likely to have English-speaking staff or experience with non-resident clients. If you are not fluent in German, French, or Italian (depending on the region), this can complicate the process. Some banks in Zurich, Geneva, and Lugano have dedicated international client teams and are more accustomed to working with foreign customers.

Private banks—firms that manage wealth rather than take deposits like a traditional bank—often have the highest minimums (2 to 5 million CHF) but offer more personalized service and may be more flexible about documentation if you have significant assets. If your deposit is below 500,000 CHF, a traditional bank is usually a better fit than a private bank.

How to start the process process

Contact the bank's international client services department directly. Do not use the general customer service line—ask specifically for the department that handles non-resident account openings. You can find contact information on the bank's website under "International Clients" or "Wealth Management." Have your passport number and approximate deposit amount ready when you call.

The bank will send you a preliminary questionnaire asking for your name, address, occupation, and the source of funds. Complete this and return it with copies of your passport and proof of address. The bank will then tell you whether you meet their basic criteria and what additional documents they need. This stage takes one to two weeks.

Once the bank confirms you are a candidate, you will be assigned a relationship manager or account officer. This person will request the full documentation package and may ask follow-up questions about your income, assets, or banking needs. If you are visiting Switzerland, the bank will schedule an in-person appointment at a branch. If you are not traveling to Switzerland soon, ask whether the bank can process the process with a video call or in-person meeting at one of their international offices.

What happens during the in-person appointment

The appointment typically lasts one to two hours. Bring original documents (passport, proof of address) and copies of everything else. The bank will verify your identity against your passport, ask you to sign account opening forms and anti-money-laundering declarations, and confirm the source of your deposit funds. They will also ask you about your banking needs—whether you plan to make frequent transfers, hold investments, or straightforward maintain a savings account.

The bank may contact your employer or a professional reference to verify your employment and income. This is standard practice and does not require your permission in advance, though the bank will usually tell you they are doing this. If you are self-employed, they may ask for additional documentation such as business registration papers or recent business tax returns.

At the end of the appointment, the bank will tell you the next steps and a timeline for account set up. They will not open the account on the spot; they will submit your process to their compliance and risk teams for final approval. This stage takes two to six weeks.

Costs and ongoing requirements

Swiss banks charge account maintenance fees that vary widely. A basic savings account may cost 200 to 500 CHF per year. Investment or wealth management accounts typically charge 0.5% to 1% of assets under management annually, plus transaction fees. Some banks waive maintenance fees if you maintain a minimum balance or generate sufficient trading activity. Ask about the full fee schedule before you open the account.

Once your account is open, you must maintain compliance with your home country's tax laws. This means reporting the account to your tax authority if required (the U.S. requires U.S. citizens to report foreign accounts over 10,000 USD on the FBAR form, for example). The Swiss bank will report your account information to your home country's tax authority automatically under CRS, so your tax authority will know the account exists whether or not you report it yourself.

You will also receive annual account statements and tax documentation from the bank. Keep these for your records and provide them to your tax advisor or accountant. If you move to a new country or change your tax residency, notify the bank when ready—they need to update their records and may need to report the account to a different tax authority.

Alternatives if you do not meet the minimum deposit requirement

If your deposit is below the bank's minimum, you have a few options. Some Swiss banks offer accounts through their online platforms with lower minimums, though these typically do not include wealth management services or a dedicated relationship manager. You can also look at Swiss neo-banks or fintech platforms that offer accounts to non-residents with lower minimums, though these are newer and less established than traditional banks.

Another route is to open an account in your home country with a bank that has a Swiss subsidiary or partnership. This does not give you a Swiss bank account, but it may give you access to Swiss investment products or currency accounts without the high minimum. A third option is to work with a Swiss financial advisor or wealth manager who can invest your money on your behalf without you holding a direct account with the bank—though this typically requires a minimum of 500,000 CHF and involves paying advisory fees.

Frequently Asked Questions

Can I open a Swiss bank account if I am a U.S. citizen?

Yes, but it is more complicated than for other nationalities. U.S. banks must comply with FATCA, which requires them to report U.S. citizen accounts to the IRS. Many Swiss banks have stopped accepting U.S. clients because of the compliance burden, but major banks like UBS still do. You will need to provide a U.S. tax identification number and sign additional FATCA declarations.

How long does it actually take from first contact to having money in the account?

Four to twelve weeks is typical. The first two weeks cover the preliminary questionnaire and initial screening. The next four to eight weeks cover document review, compliance checks, and final approval. Once approved, the account opens within days, but you should plan for the full timeline before counting on the account being active.

What if the bank rejects my process?

Banks rarely explain rejections in detail, but common reasons include insufficient documentation of income source, concerns about the origin of funds, or the bank's decision that your banking needs do not fit their service model. If rejected, you can try a different bank, but the same issues may arise. Working with a Swiss financial advisor can sometimes help clarify what documentation the bank needs.

Do I need to be a Swiss resident or citizen?

No. Non-residents and non-citizens open Swiss bank accounts regularly. You do need to be able to prove your identity and the source of your funds, and you must comply with your home country's tax reporting requirements, but residency or citizenship is not required.

Can I move money in and out of the account freely?

Yes, once the account is open. There are no restrictions on transfers in or out, though large or frequent transfers may trigger additional reporting or questions from the bank's compliance team. International wire transfers typically take two to five business days and may incur fees of 15 to 50 CHF per transfer depending on the bank and destination country.
