Business Banking and Annual Compliance in Switzerland

Opening a corporate bank account in Switzerland is not a formality. It is a gated process governed by some of the strictest anti-money laundering rules in Europe, and the bank’s decision is neither automatic nor guaranteed. For a newly incorporated company, the account opening is the step that transforms a legal shell into a functioning business — without it, the company cannot receive payments, pay suppliers, or even complete the share capital deposit required for registration.

Once the company is operational, a separate set of obligations takes over. Swiss law imposes annual compliance duties on every registered entity: financial statements must be prepared, tax returns filed at federal and cantonal level, social insurance contributions reconciled, and — depending on the company’s size — an audit completed. Missing these deadlines triggers penalties, discretionary assessments, and in serious cases, personal liability for directors.

This guide covers both sides: the banking process and the ongoing compliance framework. For focused guides, see opening a bank account and annual compliance. If you are still in the planning stage, read this alongside the company registration guide and the corporate tax overview.

How do you open a corporate bank account in Switzerland?

Every Swiss GmbH and AG needs at least one corporate bank account. For capital companies (GmbH and AG), a bank account is required before incorporation: the share capital must be deposited into a blocked account (Liberierungskonto) at a Swiss bank before the notarial deed of incorporation can be executed.

The process is straightforward in concept but rigorous in execution. Swiss banks are subject to the Federal Anti-Money Laundering Act (Geldwaeschereigesetz, GwG/AMLA) and FINMA’s implementing ordinances, which require them to verify the identity of every account holder, understand the purpose of the business relationship, and identify the beneficial owners of the company. This is not a tick-box exercise. Banks conduct genuine due diligence, and they decline applications that do not meet their risk appetite.

Typical timeline: Two to six weeks from submission of a complete application. Simple cases with Swiss-resident directors and a transparent ownership structure are processed fastest. Complex structures, non-resident owners, or higher-risk industries extend the timeline.

The bank selection matters. Different institutions have different risk appetites, fee structures, minimum balance requirements, and service levels. A rejection from one bank does not mean every bank will decline — but it does mean the application needs to be structured more carefully for the next approach.

What documents are required for a Swiss business account?

The exact list varies by bank, but the following documents are required by virtually every Swiss institution:

Corporate documents:

• Certified extract from the Commercial Register (Handelsregisterauszug) — not older than three months
• Articles of association (Statuten) — certified copy
• Organisational regulations (Organisationsreglement), if any
• Board resolution authorising the account opening and designating authorised signatories
• Shareholder register showing current ownership

Personal identification (for each director, signatory, and beneficial owner):

• Valid passport or Swiss identity card — certified copy
• Proof of residential address (utility bill or residence certificate, not older than three months)
• Curriculum vitae or professional background summary

Business documentation:

• Business plan or description of planned activities
• Expected transaction volumes and currencies
• Source of funds for the initial deposit and anticipated incoming payments
• Information on key business partners (customers and suppliers)

Beneficial ownership declaration:

• Form A (Declaration of Beneficial Owner) under the Agreement on the Swiss Banks’ Code of Conduct (VSB/CDB) — identifies the natural persons who ultimately control the company

Banks may request additional documents depending on the industry, the countries involved, and the complexity of the ownership structure. Companies in regulated sectors (financial services, crypto, commodities) should expect supplementary questionnaires.

What does the KYC and AML process involve?

KYC (Know Your Customer) and AML (Anti-Money Laundering) compliance is not a one-time gate. It is an ongoing obligation that the bank owes to FINMA, and it shapes the entire banking relationship.

At account opening, the bank performs initial due diligence:

1. Identity verification. The bank verifies the identity of all directors, signatories, and beneficial owners against their identification documents. For non-residents who cannot appear in person, verification may be conducted through a Swiss notary, a correspondent bank, or a certified video-identification process.

2. Beneficial ownership determination. Under AMLA, the bank must identify every natural person who directly or indirectly controls 25 per cent or more of the company. For complex group structures, this requires tracing the ownership chain through multiple entities to the ultimate beneficial owner.

3. Risk classification. The bank assigns a risk category to the relationship based on factors including the client’s country of origin, the nature of the business, the expected transaction volume, and whether the beneficial owners are politically exposed persons (PEPs). Higher-risk clients face enhanced due diligence — more documentation, more questions, more senior approval.

4. Plausibility check. The bank assesses whether the stated business purpose, expected transaction patterns, and source of funds are plausible and consistent. A newly incorporated trading company expecting CHF 50 million in monthly turnover will face harder questions than a consultancy expecting CHF 20,000.

Ongoing monitoring continues throughout the relationship. Banks monitor transactions for unusual patterns, conduct periodic reviews (typically annually for higher-risk clients), and may request updated documentation. Suspicious transactions must be reported to the Money Laundering Reporting Office (MROS). If the bank determines that the relationship no longer meets its risk criteria, it may terminate the account — sometimes with very short notice.

Which Swiss bank should you choose for a corporate account?

The choice of bank affects fees, service quality, digital capabilities, and the likelihood of account approval. The following comparison covers the major institutions that serve corporate clients.

UBS is the default choice for internationally oriented companies. Following its acquisition of Credit Suisse in 2023, UBS is now Switzerland’s dominant universal bank. It offers the broadest range of corporate services — multi-currency accounts, letters of credit, trade finance, treasury management — but its fee structure reflects that breadth. UBS is also the most demanding in its KYC requirements, particularly for clients with cross-border structures.

Zuercher Kantonalbank (ZKB) is the largest cantonal bank and benefits from a state guarantee by the canton of Zurich. It is a strong choice for companies domiciled in the Zurich region and offers competitive corporate lending. ZKB’s digital banking platform has improved substantially in recent years. Its risk appetite for international clients is more conservative than UBS’s.

Raiffeisen operates as a cooperative with over 220 local banks across Switzerland. It is the strongest option for small businesses that value a local banking relationship and need straightforward services — payments, a business credit card, and perhaps a credit line. Raiffeisen’s KYC process is generally faster for straightforward domestic companies.

PostFinance offers the lowest fees and the best digital experience among traditional Swiss banks. It does not hold a full banking licence (it operates under a special federal law) and does not offer traditional lending products. For companies that need a payment account and digital banking without credit facilities, PostFinance is hard to beat on price.

Other cantonal banks — Banque Cantonale Vaudoise, Basler Kantonalbank, Berner Kantonalbank, Luzerner Kantonalbank, and others — serve the same function as ZKB in their respective cantons. They often offer preferential terms for locally domiciled companies and can be easier to work with than the major national banks.

Can you use a neobank or fintech for a Swiss corporate account?

Yes, as a supplement. The Swiss banking market has seen the emergence of fintech alternatives that offer faster onboarding, lower fees, and better digital tools than traditional banks. Two stand out for corporate clients.

Amnis is a Swiss-licensed payment institution (not a bank) that specialises in corporate foreign exchange and multi-currency payments. It offers accounts in over 30 currencies with competitive exchange rates — typically 0.2 to 0.5 per cent above the interbank rate, compared with 1 to 2 per cent at traditional banks. For companies with significant cross-border payment volumes, the savings on FX alone can justify maintaining an Amnis account alongside a traditional bank account. Amnis does not accept capital deposits for company formation and is not suitable as a company’s sole banking relationship.

Alpian is Switzerland’s first digital private bank, holding a full FINMA banking licence. It targets high-net-worth individuals and entrepreneurs, offering a blend of private banking and digital convenience. For company founders who want both personal and corporate banking in one digital relationship, Alpian is worth evaluating.

Practical note: Most Swiss companies maintain their primary account at a traditional bank (for lending, capital deposits, and regulatory comfort) and add a fintech account for specific functions such as FX payments or expense management. The “one bank for everything” model is giving way to a multi-provider approach, particularly among tech-savvy founders.

Can a non-resident open a Swiss corporate bank account?

Yes, but non-resident company owners face a materially harder path to a Swiss corporate bank account. This is not discrimination — it is a direct consequence of AMLA’s risk-based approach. Non-resident beneficial owners, particularly from countries with weaker AML frameworks, trigger enhanced due diligence requirements that many banks prefer to avoid entirely.

What banks look for in non-resident applications:

• Swiss substance. A registered office with a real address (not just a c/o address at a domiciliation company), at least one Swiss-resident director or authorised signatory, and evidence that the company conducts genuine business in or from Switzerland.
• Clear business rationale. A documented explanation of why a Swiss bank account is necessary. “Switzerland has a good reputation” is not sufficient. Concrete reasons — Swiss clients, Swiss suppliers, a Swiss holding structure, or regulatory requirements — carry weight.
• Clean documentation. Every document must be complete, current, and properly certified or apostilled. Missing or ambiguous documents are the most common reason for rejection.
• Willingness to meet in person. Some banks require at least the initial meeting to take place in person at a Swiss branch. Others accept video identification, but face-to-face meetings signal commitment and reduce the bank’s compliance risk.

Realistic expectations: If your company has no Swiss employees, no Swiss office, and no Swiss-resident director, most mainstream banks will decline. The options narrow to specialist institutions that serve international clients — typically at higher fees and with higher minimum balances. Engaging a Swiss fiduciary or corporate service provider who has established relationships with banks can significantly improve the outcome.

For non-residents planning to start a company in Switzerland, the banking question should be addressed early — ideally before incorporation, so that the corporate structure can be designed with bankability in mind.

What is the capital deposit account (Liberierungskonto)?

Before a GmbH or AG can be incorporated, the founders must deposit the minimum share capital into a blocked account at a Swiss bank. This account is called a Liberierungskonto (capital deposit account or escrow account).

Minimum capital requirements:

• GmbH: CHF 20,000 (must be fully paid in)
• AG: CHF 100,000 (at least CHF 50,000 or 20 per cent must be paid in, whichever is greater)

The process works as follows:

1. The founders approach a bank and request a Liberierungskonto. The bank performs KYC on the founders before opening the account.
2. The founders deposit the share capital into the blocked account. The funds are frozen — they cannot be withdrawn until the company is registered in the Commercial Register.
3. The bank issues a capital deposit confirmation (Kapitaleinzahlungsbestaetigung), which the notary requires for the deed of incorporation.
4. After the company is entered in the Commercial Register, the bank converts the blocked account into a regular corporate account and releases the funds.

Timing consideration: The capital deposit account should be opened before the notary appointment is scheduled, because the notary will not proceed without the bank’s confirmation. Since the bank’s KYC process takes one to three weeks, founders should allow at least three weeks between first contacting the bank and the planned incorporation date.

Not every bank offers Liberierungskonti. Some smaller institutions and all fintech providers do not. Confirm this capability before beginning the application. The major banks (UBS, ZKB, Raiffeisen, cantonal banks) and PostFinance all offer capital deposit accounts as a standard service.

For full details on the company registration process, including the notarial deed, Commercial Register filing, and timeline, see our dedicated guide. The choice of company type determines the capital requirement and therefore the amount that must be deposited.

What are the annual compliance obligations for Swiss companies?

Once a Swiss company is operational, it enters a recurring cycle of compliance duties. These obligations apply to every registered legal entity — GmbH, AG, branch office — regardless of size, revenue, or industry. The scope increases with company size, but no company is exempt from the basics.

The four pillars of annual compliance are:

1. Financial statements — preparation and approval
2. Tax returns — federal, cantonal, and municipal
3. Social insurance declarations — AHV/IV/EO and other contributions
4. Annual general meeting — shareholder approval of accounts and discharge of directors

Failure to meet these obligations does not go unnoticed. Swiss authorities actively follow up on missing filings, and the consequences escalate from reminder fees to discretionary assessments to criminal penalties.

What financial statements does Swiss law require?

The Swiss Code of Obligations (OR Art. 957–963) requires every company entered in the Commercial Register to maintain proper books and prepare annual financial statements. The requirements scale with the size and complexity of the entity.

Who Must Prepare Financial Statements

All legal entities registered in the Commercial Register must prepare financial statements, including:

• GmbHs and AGs (regardless of size)
• Branches of foreign companies
• Sole proprietorships and partnerships with annual revenue exceeding CHF 500,000
• Foundations and associations, if they are required to be registered

What the Financial Statements Must Include

For smaller entities (sole proprietorships and partnerships below CHF 500,000 in revenue): a simplified income and expense statement plus a statement of assets and liabilities is sufficient.

For all other entities (OR Art. 958):

For larger companies (those required to prepare consolidated accounts or subject to ordinary audit): additional disclosures are required under OR Art. 961–961d, including a cash flow statement, a management report, and more detailed notes.

Financial statements must be prepared within six months of the financial year-end. For a company with a 31 December year-end, the deadline for preparing the accounts is 30 June of the following year. The statements must then be approved by the annual general meeting, which must be held within six months of the year-end (OR Art. 699).

Accounting Standards

Swiss law prescribes minimum requirements (OR Art. 957a–963), but companies are free to apply more detailed standards. The options are:

• Swiss GAAP FER — the standard framework for Swiss SMEs. Required for listed companies on BX Swiss and recommended for larger private companies.
• IFRS — required for companies listed on SIX Swiss Exchange. Permitted on a voluntary basis for any company.
• OR minimum — sufficient for small private companies with no external reporting obligations.

The choice of accounting standard affects the complexity and cost of the annual accounts but does not change the tax base, which is always derived from the statutory (OR-based) financial statements.

When are tax returns due in each Swiss canton?

Corporate tax returns in Switzerland are filed separately at the federal and cantonal-municipal level, though in practice most cantons use a combined form that serves both purposes. The deadline depends on the canton where the company is domiciled.

Deadlines assume a 31 December financial year-end. Companies with a different year-end receive adjusted deadlines.

Extension requests are routine in Switzerland. Most cantons grant the first extension automatically upon written or online request. Some cantons charge a small fee (CHF 20–50) for extensions. The key rule: always request the extension before the deadline passes. A late extension request is treated differently from a timely one, and some cantons do not grant retroactive extensions.

Provisional tax payments. Most cantons require provisional tax payments during the current financial year, based on the prior year’s liability or the company’s own estimate. These instalments are typically due quarterly or semi-annually. The definitive assessment, issued after the tax return is processed, reconciles provisional payments against the actual liability. Any overpayment is refunded; any shortfall accrues interest.

For the complete picture of Swiss corporate tax rates and how they affect your filing, see our canton-by-canton guide.

What social insurance declarations must Swiss employers file?

Every Swiss employer must register with the cantonal compensation office (Ausgleichskasse) and make contributions to the social insurance system. The primary schemes are:

Annual reconciliation: The compensation office sends a reconciliation form (Jahresabrechnung) in January of each year. The employer must declare the actual salary totals paid during the prior year by 30 January. Based on this declaration, the office calculates the definitive contributions and reconciles them against the provisional payments made during the year.

Director compensation (salary and bonuses) for directors who are also employees is subject to the same contributions. Dividend distributions to shareholders are not subject to social insurance contributions, though the authorities may reclassify “excessive” dividends as disguised salary if the shareholder-director’s declared salary is unreasonably low relative to the company’s profit.

Companies with employees must also maintain accident insurance (UVG) through a licensed insurer and enrol employees earning above the BVG threshold (currently CHF 22,050 per year) in an occupational pension scheme.

What are the audit requirements for Swiss companies?

Swiss audit requirements follow a three-tier system defined in OR Art. 727–727c:

Ordinary Audit

Required if the company exceeds two of the following three thresholds in two consecutive financial years:

• Total assets: CHF 20 million
• Revenue: CHF 40 million
• Employees: 250 full-time equivalents

An ordinary audit must be conducted by a licensed audit expert (zugelassener Revisionsexperte) or a state-supervised audit firm. The auditor examines the financial statements in accordance with Swiss Auditing Standards and issues an opinion on whether the statements give a true and fair view. The audit report is presented to the annual general meeting.

Companies listed on a Swiss stock exchange and public-interest entities also require an ordinary audit regardless of size.

Limited Audit (Review)

Companies that do not meet the ordinary-audit thresholds but have more than 10 full-time employees are subject to a limited audit (eingeschraenkte Revision). This is a review engagement, not a full audit. The reviewer performs analytical procedures and inquiries but does not conduct the substantive testing required in an ordinary audit. The scope and cost are significantly less.

A limited audit must be conducted by a licensed auditor (zugelassener Revisor) — a lower qualification threshold than the ordinary audit requires.

Opting-Out

Companies with 10 or fewer full-time employees may waive the audit requirement entirely if all shareholders unanimously consent. This is the opting-out provision under OR Art. 727a para. 2.

The opting-out must be documented in the minutes of the shareholders’ meeting and registered with the Commercial Register (by noting the absence of an auditor in the register entry). Once opted out, the company has no audit obligation until it exceeds the 10-FTE threshold or a shareholder withdraws consent.

Practical reality: The vast majority of newly incorporated GmbHs and small AGs opt out. An audit — even a limited one — costs CHF 3,000 to CHF 15,000 annually, which is a meaningful expense for a company with fewer than 10 employees. Opting out saves that cost without any operational downside, provided the shareholders trust the directors’ financial management.

For detailed guidance on audit requirements, including how to switch between categories, see our audit requirements guide.

What are the penalties for late filing in Switzerland?

Swiss authorities take compliance deadlines seriously. The penalty structure escalates:

Tax Returns

A discretionary assessment is the most common and most costly consequence. The tax authority estimates the company’s income based on available information (industry benchmarks, prior years, bank data) and issues an assessment. The burden then shifts to the taxpayer to prove the assessment is too high — which requires filing the actual return with supporting documentation, often at a point when the company is already under scrutiny.

Financial Statements and Annual Meeting

Failure to prepare financial statements or hold the annual general meeting within the legally required timeframe can result in:

• Personal liability of directors for damages caused by the breach (OR Art. 754)
• Application by a shareholder or creditor to the court for remedial measures
• In extreme cases, a complaint to the supervisory authority, which can lead to dissolution proceedings

Social Insurance

Late or incomplete social insurance declarations trigger penalty interest and, for repeated offences, administrative fines. The compensation office may also issue discretionary contribution assessments, analogous to the tax authority’s approach.

What does the annual compliance calendar look like?

For a company with a standard 31 December financial year-end, the recurring compliance cycle follows this pattern:

This calendar becomes second nature after the first full cycle. For companies that outsource bookkeeping and tax compliance to a fiduciary firm — the standard approach for small companies in Switzerland — most of these deadlines are managed by the fiduciary, with the directors’ involvement limited to reviewing and approving the accounts and attending the annual general meeting.

Frequently Asked Questions

How long does it take to open a corporate bank account in Switzerland?

The typical timeline is two to six weeks from submission of a complete application. Straightforward cases with Swiss-resident directors and a clear business model are often processed within two weeks. Applications involving non-resident beneficial owners, complex group structures, or industries classified as higher risk under anti-money laundering rules — such as cryptocurrency, commodity trading, or payment services — may take four to six weeks or longer. The single most common cause of delay is incomplete documentation, so assembling every required document before approaching the bank is the most effective way to accelerate the process.

Can a non-resident open a Swiss corporate bank account?

Yes, but it is significantly harder. Swiss banks require evidence of genuine economic substance in Switzerland — a real office, Swiss-resident employees, or demonstrable business reasons for a Swiss account. A shell company with no Swiss operations and non-resident directors will be declined by most banks. If your company has a Swiss registered office and at least one Swiss-resident director or signatory, your chances improve considerably. Some banks specialise in serving international clients, but expect enhanced due diligence, higher minimum deposits, and longer processing times.

What happens if a Swiss company misses its tax return deadline?

The immediate consequence is a reminder notice (Mahnung) from the cantonal tax authority, typically with a penalty fee of CHF 50 to CHF 1,000. If the return is still not filed after the reminder, the authority issues a discretionary assessment (Ermessensveranlagung), estimating the company's taxable income — usually generously, resulting in a higher tax bill than a properly filed return would produce. Penalty interest of 3 to 5 per cent per annum accrues on any unpaid balance from the original due date. Repeated non-compliance can result in criminal fines under DBG Art. 174-176.

Does every Swiss company need an audit?

No. Swiss law distinguishes three categories. Companies that exceed two of three thresholds — CHF 20 million in total assets, CHF 40 million in revenue, or 250 full-time employees — in two consecutive years require an ordinary audit by a licensed audit firm. Companies below these thresholds but with more than 10 full-time employees require a limited audit (review). Companies with 10 or fewer full-time employees may opt out of any audit entirely if all shareholders unanimously consent, a mechanism known as opting-out under OR Art. 727a. The vast majority of newly incorporated GmbHs and small AGs use the opting-out provision.

What is a Form A beneficial ownership declaration and why do Swiss banks require it?

Form A (Declaration of Beneficial Owner) is a standardised document developed under the Agreement on the Swiss Banks' Code of Conduct (VSB/CDB). It identifies the natural persons who ultimately own or control more than 25% of a company's shares or voting rights. Swiss banks are required under the Federal Anti-Money Laundering Act (AMLA/GwG) to identify and document the beneficial ownership of every corporate customer. Without a completed Form A, no Swiss bank will open a corporate account. The declaration must be updated if ownership changes by more than 5 percentage points.

Can a Swiss company use a neo-bank or fintech instead of a traditional bank?

Yes. Swiss-licensed fintechs and neo-banks such as Neon Business, WISE Business, and Airwallex accept Swiss corporate clients with faster onboarding times — often two to five business days compared to two to six weeks at a traditional bank. However, fintech accounts typically have lower credit limits, no overdraft facilities, limited cash-handling capabilities, and may not be accepted for capital deposit (Liberierungskonto) purposes at registration. Many founders open a fintech account for day-to-day transactions whilst maintaining a traditional bank account for the capital deposit and larger financial transactions.

What documents does a Swiss company need to prepare for its annual financial statements?

A Swiss GmbH or AG must prepare annual financial statements compliant with OR Art. 957ff, including: a balance sheet, a profit and loss statement, and notes to the accounts. The accounts must reflect all transactions in the financial year and be approved by the shareholders' meeting within six months of year-end. Most small companies use Swiss GAAP Obligationenrecht (OR) as their accounting standard. Larger companies or those seeking external financing may choose Swiss GAAP FER or IFRS. The accounts form the basis for both corporate income tax returns and the annual return to the commercial register.
