Financial statements must be prepared and filed with the Commercial Register (Handelsregister), with filing deadlines varying by canton. Small and medium‑sized enterprises are not generally required to publish accounts and may qualify for an audit exemption. Preparation of accounts and the conduct of statutory audits are carried out by licensed auditors and specialised accounting firms.

Requirements regarding compulsory publication of financial statements of companies in Switzerland are limited:

  • Only standalone and consolidated financial statements of listed companies (whose shares are listed on a stock exchange) must be published;
  • Cooperatives that have at least 2 000 members;
  • Funds that must be audited according to the law.

Accounting records, accounting documents, annual accounts and auditor’s reports must be kept for ten years in the registered office of the company.

The following companies must be audited:

I. Companies that exceeded 2 of the 3 criteria in 2 straight years:

  • Balance sheet total is 20 000 000 CHF;
  • Turnover is 40 000 000 CHF;

Time frame for preparation and submission of financial statements

Switzerland has 26 cantons, confederate states, and each canton has its own time frame for filing accounts, from 6 to 9 months.

Liability for late filing of accounts

In the case of late filing of accounts or refusal to file them, penalties apply. Each of the 26 cantons has its taxation system, so penalties for companies will vary in the case of a delay in filing accounts.

Consolidated financial statements

If a company, association or fund controls one or several legal entities that must file financial statements, in addition to annual accounts the enterprise must prepare annual consolidated financial statements for all controlled entities.

Sole proprietorships and partnerships are exempt from the consolidation requirement.

A legal entity is considered to control another entity if it:

  • holds the majority of votes in the supreme management body;
  • has the right to appoint or dismiss the majority of members of the supreme management or administrative body;
  • can exert controlling influence on the entity on the basis of the articles of association, constitutive act or analogous documents.

A legal entity is exempt from the obligation to make consolidated financial statements if the entity did not exceed two of the following thresholds in two consecutive financial years:

  • Balance sheet total is 20 000 000 CHF;
  • Turnover is 40 000 000 CHF;
  • Average headcount of employees per year is 250.

Subgroups are also exempt from the consolidation requirement if consolidated financial statements of the controlling entity have been prepared, audited and provided in accordance with legislation.

Frequency Asked Questions

What is Swiss audit?
Swiss audit refers to the process of independent examination of a company’s financial statements intended to confirm their reliability, compliance with applicable law and conformity with relevant accounting standards. The auditor assesses the correctness of the accounting records, the completeness and accuracy of reported information, and whether the financial statements meet the requirements of Swiss GAAP FER, IFRS or the Swiss Code of Obligations. Upon completion of the audit an auditor’s report is issued, which may accompany the annual and consolidated financial statements when filed with the commercial register.
Is audit mandatory in Switzerland?
Audit is not mandatory for all companies in Switzerland. However, companies that exceed certain thresholds are required to undergo an audit. For example, under the Swiss Code of Obligations, joint stock companies (AG) and limited liability companies (GmbH) are required to undergo an audit if they meet two of the three following conditions for two consecutive financial years: 1) total assets of at least 20 000 000 CHF, 2) turnover of at least 40 000 000 CHF and 3) more than 250 full-time employees. Other types of companies, such as sole proprietorships or partnerships, are generally not required to undergo an audit, but they may choose to do so voluntarily.
What is the Swiss law on financial reporting?
The Swiss rules on accounting and financial reporting are contained in Titel 32 of the Swiss Code of Obligations (Articles 957 et seq.) and cover commercial bookkeeping and accounts for all undertakings, including sole traders, partnerships and legal entities. The Code sets minimum requirements for the format of the balance sheet, income statement and notes to the accounts, prescribes valuation rules for assets and liabilities, permits the creation of hidden reserves provided they do not distort the financial statements, and establishes the obligations for retention of accounting records and financial reports.
What accounting standards are used in Switzerland?
Switzerland uses two principal accounting frameworks: Swiss GAAP FER and IFRS. Swiss GAAP FER is applied across a wide range of entities — from small and medium‑sized enterprises to national groups and listed companies — and includes sector‑specific guidance for pension funds, insurance undertakings and not‑for‑profit organisations. IFRS is primarily used by multinational corporations to ensure transparency and comparability of reporting. In addition, commercial bookkeeping and financial reporting are governed by the Swiss Code of Obligations, which sets minimum requirements for the balance sheet, income statement and notes to the financial statements.
