Swiss Business Bank Account: Foreign Company vs Swiss Company with Foreign Shareholders (2026)

Scenario A — Foreign Company Opening a Swiss Bank Account

A foreign company — one incorporated in the UK, BVI, Cayman Islands, UAE, USA, or anywhere else outside Switzerland — faces a fundamentally different challenge than a Swiss company when approaching a Swiss bank. Swiss banks assess foreign companies against one core question: what is the legitimate reason this company needs to bank in Switzerland specifically? Without a convincing answer — and usually some demonstrable connection to Switzerland — most Swiss banks will decline the application before reviewing a single document.

The reason isn’t arbitrary. Under FINMA’s Anti-Money Laundering Ordinance and the Swiss Banking Due Diligence Convention (CDB 20), Swiss banks are required to assess the business rationale of every corporate relationship. A foreign company with no Swiss operations, no Swiss clients, no Swiss assets, and no Swiss counterparties is a compliance question the bank has to answer to FINMA: why are we holding this relationship? If there is no good answer, the bank’s rational choice is to decline rather than take on the AML exposure. This reality explains why most Swiss banks — including UBS for most of its retail corporate offering, PostFinance, and ZKB — will not open business accounts for foreign-incorporated entities unless there is a demonstrable Swiss nexus.

What Counts as a Swiss Nexus

Swiss nexus takes several forms, and some are stronger than others in the eyes of a bank’s compliance team. A Swiss branch registered with a cantonal commercial register is the clearest and most widely accepted nexus — the foreign company has a legal presence in Switzerland. Regular documented transactions with Swiss counterparties (suppliers, clients, service providers) establishes commercial nexus. A Swiss-resident director or authorised signatory demonstrates operational presence. Ownership of Swiss real estate or holding Swiss securities in custody creates asset nexus. A private banking anchor relationship at the same Swiss institution — where the company’s beneficial owner already has a personal account — is often the most practical path for passive holding structures.

Nexus built on paper alone — a virtual office address and a Swiss fiduciary director who signs everything without any real management involvement — is exactly what FINMA’s Due Diligence Convention targets. Banks check, and when the substance doesn’t match the structure, applications fail. Genuine economic activity or a genuine personal banking relationship at the same institution are the two most reliable nexus types.

Domiciliary Company vs Active Company — Why It Changes Everything

FINMA’s Due Diligence Convention draws a sharp line between two types of foreign corporate clients. A domiciliary company has no physical operations in its jurisdiction of incorporation — no employees, no real office, no active trade. These include most BVI, Cayman, Seychelles, and similar offshore structures used as holding vehicles. An active company generates revenue from genuine commercial operations, processes regular transactions with real counterparties, and has employees or operational staff. Swiss banks handle these two categories completely differently.

Banks That Accept Foreign Companies in 2026

The honest picture, as of May 2026, is that the field has narrowed. CIM Banque, which was the most widely recommended option for offshore holding companies through most of the 2010s, tightened its foreign corporate appetite significantly from 2020 onward and no longer actively pursues foreign corporate relationships as a growth area — the legacy book is maintained, not expanded. Relio, a FINMA-licensed Swiss fintech, is currently the fastest and most accessible path for European-owned operating companies needing a functional Swiss corporate account, but it explicitly excludes US nexus and caps deposits at CHF 100 million. For passive holding structures connected to a private banking relationship, most mid-tier and top-tier Swiss private banks will accommodate the foreign corporate vehicle through the same onboarding as the personal client.

Documents for Scenario A — Foreign Company

Foreign company documents must be apostilled under the Hague Convention and professionally translated into German, French, or English before submission to any Swiss bank. A company incorporation certificate older than six months will typically be rejected. Every document in the package needs to be current.

Scenario B — Swiss GmbH or AG with Foreign Shareholders

A Swiss-incorporated company — a GmbH or AG registered in the Swiss commercial register — is a Swiss legal entity regardless of who owns it. There are no restrictions on foreign ownership of a Swiss GmbH or AG. A company can be 100% owned by a single foreign national or by a foreign corporate entity, and it is still fully Swiss for banking purposes. The Swiss commercial register entry, the Swiss legal address, and the Swiss corporate governance structure make this an entirely different proposition for a bank compared to Scenario A.

Most Swiss banks — including UBS, ZKB, PostFinance, Migros Bank, and all cantonal banks — will consider opening a business account for a Swiss-incorporated company even when the shareholders are entirely foreign. The company is Swiss. The bank’s question is no longer “why does this company need to bank here?” — it’s “who owns this company, and does their profile pass compliance?” The focus shifts entirely from the company’s structure to the shareholders’ KYC profiles. That’s a very different problem, and a much more manageable one.

What Foreign Shareholders Change in the Banking Process

Every beneficial owner above 25% of the Swiss company must go through a full personal KYC process — exactly the same as a non-resident individual opening a personal Swiss account. This means a certified passport copy, proof of address, Tax Identification Number from the shareholder’s country of residence, and source-of-wealth documentation. For a Swiss company with three equal foreign shareholders (each at 33%), all three go through full KYC. For a company with one 100% foreign owner, that one person provides the complete personal package.

The nationality of the foreign shareholders directly affects the complexity and timeline of the application. The bank applies its country risk matrix to each shareholder’s passport profile independently. A Swiss AG owned by a German and a French national — both EU, low-risk jurisdictions — goes through standard onboarding at most Swiss banks. The same Swiss AG owned by shareholders from a FATF-listed jurisdiction, or from a country with which Switzerland has elevated compliance obligations, triggers Enhanced Due Diligence for the entire application. The company is Swiss; the risk profile is determined by who owns it.

US Shareholders — the FATCA Problem

US shareholders in a Swiss company create FATCA reporting obligations for the Swiss bank — it must identify, report, and comply with IRS disclosure requirements for any account where a US person has ownership or control. This is manageable but costly, and many Swiss banks — particularly at the SME banking tier — have decided it isn’t worth carrying for smaller relationships. ZKB and PostFinance generally accept US shareholders in Swiss companies but apply additional documentation requirements. UBS manages FATCA through its institutional infrastructure. Relio explicitly excludes US nexus at any level. Before approaching a Swiss bank with US shareholders in your Swiss company, confirm directly whether the bank accepts that profile for business accounts — it varies considerably and is worth verifying before preparing your full documentation package.

Dividends and Withholding Tax for Foreign Shareholders

When a Swiss GmbH or AG distributes dividends to its foreign shareholders, Switzerland applies a 35% withholding tax at source. This is not a banking matter — it’s a tax matter — but it directly affects how foreign shareholders structure their Swiss company relationships and is worth understanding before incorporating. Under Switzerland’s network of Double Taxation Agreements (over 100 treaties), most foreign shareholders can claim a reduction of the 35% withholding to a treaty rate — typically 5%, 10%, or 15% depending on the country and the ownership percentage. The reduction requires a formal claim through the Swiss Federal Tax Administration. EU companies holding Swiss subsidiaries may qualify for the EU-Switzerland Bilateral Agreement’s reduced withholding arrangement, which can bring the rate to 0% under certain conditions for qualifying structures.
