Banking in Switzerland: account opening, custody and reporting

Eligibility & suitability

Choose the institution for the intended use

A Swiss banking relationship can support custody, investment management, foreign-currency accounts or business payments, but those are different products. Start with the actual need: where the client lives, where the wealth arose, the legal owner, expected balances, transaction countries and whether the account will receive commercial revenue. A private-banking investment account is not automatically suitable for high-volume merchant processing or a regulated operating business.

There is no universal Swiss minimum deposit or guaranteed onboarding time. Institutions set their own commercial thresholds, country policies and risk appetite. Obtain written confirmation of the proposed product, booking entity, account-holder eligibility, charges and permitted activity before moving assets. An introduction can help present a complete file but cannot override the bank’s compliance decision. If the relationship depends on a future residence change, disclose that plan during assessment instead of treating the first approval as permanent acceptance for every country.

Explain both the origin of wealth and the funding transfer

Swiss financial intermediaries must identify the contracting party and beneficial owner and clarify the economic background and purpose of unusual or higher-risk relationships. A passport and recent bank statement may establish identity and possession of money without explaining how the wealth was earned. Distinguish source of wealth, meaning the history that created the overall assets, from source of funds, meaning the immediate origin and path of the particular transfer.

For a business sale, a useful file can include ownership history, transaction agreements, closing statements, tax records and the bank trail. For trading or crypto wealth, explain the original capital, platforms, transaction records and conversion into banked funds. For a company or trust, provide the ownership/control chain and the relevant constitutive documents. The bank determines the evidence it will accept; more complex histories usually require more explanation rather than a promise that one standard checklist will be sufficient.

Deposit protection is different from custody protection

FINMA describes protection for eligible deposits up to CHF100,000 per client per institution. Multiple accounts at one institution do not automatically multiply that limit. The framework includes privileged treatment and the deposit-protection mechanism, with distinctions for deposits booked at Swiss and foreign branches. Confirm the legal booking entity and the status of the actual product; a familiar group name does not identify which balance-sheet claim the client holds.

Custody assets such as client securities are generally segregated from the institution’s bankruptcy estate under the applicable rules. That is different from insuring their market value. Shares, bonds and funds can lose value, issuers can default, and some structured or lending arrangements introduce separate exposures. Review cash balances, custody positions, collateral rights and any securities-lending consent individually. “Swiss bank” should never be used as shorthand for unlimited protection of every investment.

Tax reporting continues across borders

Switzerland participates in automatic exchange of financial-account information. Reporting financial institutions collect relevant identification, account and financial data for reportable clients and transmit it through the FTA to the appropriate partner authorities. A Swiss account therefore does not make otherwise taxable foreign income invisible or remove reporting in the client’s residence country.

Provide accurate tax-residence self-certifications and identification numbers, and update them after a move. An entity account can require classification of the entity and relevant controlling persons; a company incorporated in one country is not automatically reportable only there. Preserve statements and income records for tax filings, withholding-tax relief and reconciliation of reported balances. Confidentiality against unauthorised disclosure is different from statutory reporting to tax or law-enforcement authorities. The account should fit a documented, reportable structure rather than depend on an assumption of secrecy.

Opening the account is the beginning of the relationship

After preliminary acceptance, complete the bank’s identification and beneficial-ownership procedure, submit the wealth/funds evidence and tax forms, and respond to the compliance review. Execute the final terms only after understanding the fees, custody arrangement and investment mandate. Coordinate the initial transfer with the institution, preserve the funding trail and verify that the correct account and currency were credited.

Ongoing reviews may request updated residence, ownership, business and source-of-funds information. A new country of residence, unusual transaction or material business change can affect the relationship. Keep a current document file and notify the bank before a significant change where possible. Account opening, investment advice, residence planning and tax treatment are separate workstreams; successful onboarding does not certify the structure’s legal or tax effectiveness. Offshore Capitalist can help organise the cross-border requirements and introductions, while the institution retains its own acceptance decision.
