What Swiss banks require from foreign customers

Swiss banks will open accounts for non-residents, but the process is slower and more document-heavy than opening an account in your home country. Most Swiss banks now require a minimum deposit between 250,000 and 1 million Swiss francs (CHF)—roughly $280,000 to $1.1 million USD, though exchange rates shift daily. Some smaller private banks have lower minimums, and a few online banks accept deposits as low as 10,000 CHF, but these are exceptions.

The core requirement is proof of identity and source of funds. You will need a valid passport, proof of your current address (a utility bill or bank statement dated within the last three months), and documentation showing where your money comes from. If you are employed, that means recent pay stubs and an employment letter. If you are self-employed or own a business, you will need tax returns from the past two years and possibly business registration documents. If your funds come from investments, inheritance, or real estate sales, you will need statements or deeds showing the source.

Swiss banks also conduct sanctions and politically exposed person (PEP) screening. They check whether you appear on international sanctions lists and whether you hold a political office or are a close relative of someone who does. This is not a barrier for most people, but it adds time to the approval process—typically four to eight weeks.

Key Takeaways

  • Most Swiss banks require a minimum deposit of 250,000 to 1 million CHF and will not open accounts below that threshold without a specific reason like inheritance management or business operations.
  • You must provide a valid passport, proof of address, and documentation of where your money comes from, such as tax returns, employment letters, or investment statements.
  • Swiss banks conduct background screening for sanctions and political connections, which typically adds four to eight weeks to the approval timeline.
  • Opening an account in person at a Swiss bank branch is faster than doing it remotely, but remote opening is possible through some banks if you use a video identification process.
  • Swiss bank accounts are subject to automatic information exchange with your home country's tax authority under FATCA and similar agreements, so you cannot use them to hide income.

The difference between opening in person and remotely

If you travel to Switzerland and visit a bank branch in person, the process moves faster. You can bring your documents, meet with a relationship manager, and often receive preliminary approval on the same day. The bank will still conduct background checks and verify your source of funds, but they do not need to arrange video identification or courier documents back and forth. Most major Swiss banks have branches in Zurich, Geneva, Bern, and Lucerne, and some have representatives in major cities outside Switzerland.

Remote opening is possible but requires more steps. The bank will ask you to upload scans of your passport, proof of address, and financial documents through a secure portal. You will then participate in a video identification call with a bank employee, usually scheduled within one to two weeks. During this call, the bank verifies that you are the person in your passport photo and that you understand the account terms. After that, you sign documents electronically and arrange the initial deposit via wire transfer.

Remote opening typically takes six to twelve weeks from start to finish, compared to two to four weeks if you open in person. The delay comes from document verification, background screening, and the bank's internal review process—not from your actions.

Which Swiss banks accept non-residents with lower minimums

The largest Swiss banks—UBS, Credit Suisse, and Julius Baer—generally require minimums of 500,000 CHF or higher and prefer clients with substantial assets or business reasons for the account. They are less likely to open accounts for individuals who simply want a Swiss bank account as a savings vehicle.

Smaller private banks and wealth managers are more flexible. Banks like Vontobel, Pictet, and Lombard Odier sometimes open accounts for non-residents with minimums between 100,000 and 250,000 CHF. Online banks like Neon and Wise offer accounts with much lower minimums—sometimes as low as 1 CHF—but these are transaction accounts, not investment or wealth management accounts, and they do not offer the same privacy or services as traditional Swiss private banks.

If your goal is simply to hold Swiss francs or make transfers in CHF, an online account may be sufficient. If you want investment management, tax planning, or discretionary services, you will need a private bank and a higher minimum deposit.

How to verify your source of funds

Swiss banks use Know Your Customer (KYC) rules to prevent money laundering. This means they must understand where your money comes from and why you are depositing it. The bank will ask you to explain the source in writing and provide supporting documents.

If your money comes from employment, provide your last two years of tax returns, recent pay stubs, and a letter from your employer confirming your position and salary. If you are self-employed, provide business tax returns, a business registration certificate, and bank statements showing regular business income. If you received an inheritance, provide a copy of the will or inheritance certificate and the bank statement showing the deposit into your account. If you sold property or investments, provide the deed or brokerage statement and proof that the sale proceeds arrived in your account.

The bank may ask follow-up questions if the source is unclear or if the amount seems large relative to your stated income. For example, if you claim to earn $50,000 per year but want to deposit $500,000, the bank will ask where the additional funds came from. Be prepared to explain gifts, inheritances, or other sources in detail.

Tax reporting and automatic information exchange

A Swiss bank account does not provide tax privacy. Under the Foreign Account Tax Compliance Act (FATCA), Swiss banks must report accounts held by U.S. citizens to the Internal Revenue Service. Similar agreements exist between Switzerland and most other countries under the Common Reporting Standard (CRS). This means your Swiss bank will automatically send information about your account balance and income to your home country's tax authority every year.

If you are a U.S. citizen, you must report the account to the U.S. Treasury Department using the Foreign Bank Account Report (FBAR) if the account balance exceeds $10,000 at any point during the year. You must also report any income earned in the account on your U.S. tax return. Failure to report can result in penalties of 25 to 50 percent of the account balance.

Citizens of other countries should check their home country's tax authority for similar reporting requirements. Most developed nations now exchange financial information with Switzerland automatically, so opening a Swiss account to avoid taxes is not a viable strategy.

What happens after your account opens

Once approved, the bank will send you account details, online banking credentials, and a debit card if you requested one. You will arrange your initial deposit via international wire transfer. The bank will provide wire instructions including the IBAN (International Bank Account Number) and SWIFT code. Wire transfers from outside Switzerland typically take three to five business days to arrive.

After the account is open, you can manage it online, by phone, or in person at a branch. Most Swiss banks charge annual fees ranging from 500 to 2,000 CHF depending on the account type and your balance. Some banks waive fees if you maintain a minimum balance or if you use their investment services. Ask about fees before opening the account—they vary widely.

If you need to close the account later, notify the bank in writing. They will freeze the account, settle any outstanding transactions, and wire the remaining balance back to you. Closure typically takes two to four weeks.

Frequently Asked Questions

Can I open a Swiss bank account if I am not a Swiss citizen?

Yes. Swiss banks open accounts for non-residents from most countries. You do not need to be a Swiss citizen or resident. However, you must meet the bank's minimum deposit requirement and provide documentation of your identity and source of funds. Some countries face restrictions due to sanctions, but most people can open an account if they meet the financial threshold.

What if my country has restrictions on holding foreign bank accounts?

Check your home country's laws before opening a Swiss account. Some countries require you to report foreign accounts to their government or restrict the amount you can hold abroad. Your tax authority or a local accountant can tell you whether opening a Swiss account is permitted and what reporting you must do.

Can I use a Swiss bank account to avoid paying taxes?

No. Swiss banks report account information to your home country's tax authority automatically under FATCA and CRS agreements. You must report the account and any income it generates on your home country's tax return. Using a Swiss account to hide income is illegal and can result in criminal prosecution, not just tax penalties.

How long does it take to open a Swiss bank account?

In person at a branch, two to four weeks. Remotely, six to twelve weeks. The delay comes from document verification, background screening, and the bank's internal review. You cannot speed this up significantly, though some banks are faster than others.

What is the minimum deposit to open a Swiss bank account?

It varies by bank. Large private banks typically require 250,000 to 1 million CHF. Smaller banks may accept 100,000 to 250,000 CHF. Online banks sometimes accept deposits as low as 1 to 10,000 CHF, but these offer fewer services than traditional Swiss banks. Ask the specific bank for their current minimum before you begin the process.
