About Accounting & Auditing Law in Muttenz, Switzerland

Accounting and auditing rules in Muttenz are governed primarily by Swiss federal law. The Swiss Code of Obligations defines how businesses must keep books and prepare financial statements, while the Audit Oversight Act regulates who may perform statutory audits and how audits are supervised. Muttenz is in the canton of Basel-Landschaft, so company registrations go through the Basel-Landschaft Commercial Registry, and tax filings are handled by the Basel-Landschaft tax authorities. In practice, this means that a company in Muttenz follows the same national accounting and audit framework as the rest of Switzerland, with certain processes and administrative interactions handled locally at the cantonal level.

Swiss law sets clear thresholds for bookkeeping, financial reporting, and audit requirements. Smaller businesses may qualify for simplified accounting or an audit opt-out, while larger or public interest companies face ordinary audit and enhanced reporting obligations. Professional auditors are licensed and supervised at the federal level, and companies can choose Swiss GAAP FER or IFRS where appropriate, with statutory minimums defined in the Code of Obligations.

Why You May Need a Lawyer

Many business owners handle day-to-day bookkeeping with an accountant, but legal advice becomes important when obligations or risks change. You may need a lawyer if you are founding or restructuring a company and want to select the right accounting framework and audit status, considering options such as an audit opt-out for very small entities. You may also need legal support if you are approaching the thresholds that trigger an ordinary audit, or if you face a special audit connected to capital increases, mergers, demergers, or changes to share capital currency.

Lawyers are frequently involved in drafting shareholder agreements that address audit choices and information rights, in managing disputes between shareholders about transparency or dividend policy, and in advising boards on their duties related to internal controls and going concern assessments. If an investigation, whistleblower report, or suspected financial irregularity arises, counsel can coordinate with auditors and forensic accountants to manage legal privilege and regulatory notifications. Legal advice is also valuable for non-financial reporting under Swiss law, supply chain due diligence duties, data protection compliance in financial records, and responses to inquiries from tax authorities or regulators.

Local Laws Overview

Swiss Code of Obligations accounting rules apply in Muttenz. Sole proprietorships and partnerships with annual revenues of at least CHF 500,000 must keep full accounts and prepare financial statements. Those below this threshold may keep simplified accounts that track receipts, payments, and assets and liabilities. Corporations such as AG and GmbH must always prepare a balance sheet, income statement, and notes, and the board is responsible for accurate accounts and an appropriate internal control environment. Records must generally be retained for 10 years, and electronic archiving is permitted if records remain complete, secure, and accessible in Switzerland or are accessible from Switzerland.

Financial statements are prepared under Swiss law and may be presented using Swiss GAAP FER or IFRS where required by listing rules or chosen voluntarily. The Code of Obligations allows accounting records in a Swiss national language or in English. Since 2023, companies whose share capital is denominated in a widely used foreign currency may keep and present accounts in that same currency, subject to specific legal conditions.

Audit requirements are tiered. An ordinary audit is required for public companies and for entities that exceed two of the following three thresholds in two successive financial years: CHF 20 million in total assets, CHF 40 million in sales, and 250 full time equivalents. Companies that prepare consolidated financial statements generally also require an ordinary audit. Entities that do not meet these criteria are typically subject to a limited statutory examination unless all shareholders consent to an audit opt-out and the company has fewer than 10 full time equivalents on average. Auditors must be licensed and independent, and they follow Swiss auditing standards.

Non-financial disclosure duties apply to certain large public interest companies. These include reporting on environmental, social, employee, human rights, and anti-corruption matters, and separate due diligence and reporting obligations related to conflict minerals and child labor supply chains, with audit requirements in some cases. VAT, corporate income tax, and withholding tax are administered by federal and cantonal authorities, and while financial statements are not generally published for private companies, they are reviewed by shareholders and provided to tax authorities with returns. In Muttenz, incorporations, changes to auditors, and other company filings are recorded with the Basel-Landschaft Commercial Registry, and tax returns are filed with the Basel-Landschaft tax administration.

Frequently Asked Questions

Do I need an audit for my GmbH in Muttenz

Most Swiss GmbH that do not exceed the ordinary audit thresholds will be subject to a limited statutory examination. If your company has fewer than 10 full time equivalents and all shareholders unanimously agree, you can opt out of the audit. If you exceed the size thresholds or are a public interest entity, you will need an ordinary audit.

What is the difference between an ordinary audit and a limited statutory examination

An ordinary audit provides a higher level of assurance and includes testing of internal controls and more extensive procedures. A limited examination is a review primarily based on inquiries and analytical procedures, providing a lower level of assurance. The type required depends on your companys size and status.

Can we prepare our accounts in English or in a foreign currency

Yes. Accounting records may be kept in a Swiss national language or in English. If your companys share capital is in a widely used foreign currency under Swiss law, you may also keep and present financial statements in that currency, provided legal conditions are met.

How long must we keep our accounting records

Swiss law generally requires retention for 10 years from the end of the financial year. Electronic archiving is allowed if integrity, readability, and accessibility are ensured, and records must be accessible from Switzerland.

When is consolidated financial reporting required

A parent company must prepare consolidated financial statements if it controls one or more subsidiaries and exceeds certain size criteria, or if required for a true and fair view. Entities with consolidated reporting obligations typically require an ordinary audit.

Can a small company opt out of an audit after it has already appointed an auditor

Yes, if the company has fewer than 10 full time equivalents and all shareholders consent, it can resolve to opt out and file the change with the commercial register. Check contractual and regulatory obligations first, as lenders or agreements may require an audit.

Who licenses and supervises auditors in Switzerland

Auditors and audit firms are licensed and supervised by the Federal Audit Oversight Authority. State supervised audit firms are required for public interest entities, while licensed audit experts may perform ordinary audits for other companies and limited examinations.

Are private companies required to publish their financial statements

Private Swiss companies generally present their financial statements to shareholders and submit them to tax authorities, but they are not usually required to publish them publicly. Listed companies must publish in line with stock exchange rules.

What happens if we do not comply with accounting or audit rules

Non compliance can lead to commercial register objections, shareholder challenges, tax consequences, and potential civil or criminal liability for responsible persons in serious cases. Banks and investors may also impose sanctions or accelerate financing if covenants are breached.

How do VAT and income tax interact with accounting in Muttenz

Your bookkeeping supports VAT returns filed with the Federal Tax Administration and income tax returns filed with Basel Landschaft tax authorities. Accurate and timely accounts help ensure correct tax assessments and reduce the risk of penalties and interest.

Next Steps

Clarify your business profile and obligations by assessing your legal form, revenue, total assets, and average headcount. This helps determine whether simplified accounting, a limited examination, or an ordinary audit applies, and whether non financial reporting requirements may be triggered.

Collect your core documents, including articles of association, shareholder agreements, prior year financial statements, the current chart of accounts, major contracts, financing agreements, and any internal control or risk management policies. Having these ready will streamline professional reviews and reduce fees.

Engage qualified professionals. For statutory audits, select a licensed auditor appropriate to your status. For legal interpretation of audit thresholds, opt out procedures, corporate governance, and non financial reporting duties, speak with a lawyer who focuses on Swiss corporate and accounting law in the Basel region.

Confirm timelines and deliverables in writing. Agree on the scope of work, independence and conflict checks for auditors, the audit or review timetable, management representations, and any tax or regulatory filings. Ensure your board and shareholders schedule the general meeting to approve the annual accounts on time.

Implement practical compliance measures. Maintain reliable bookkeeping, reconciliations, and documentation of significant judgments. If you are approaching a threshold, consider early planning for an ordinary audit and enhance your internal control system accordingly.

Review outcomes and follow up. After your financial statements are finalized and approved, address any audit recommendations, update corporate filings with the commercial registry if there are changes to the auditor or capital, and prepare for tax submissions with supporting schedules.

If you are uncertain about any requirement in Muttenz or Basel Landschaft, consult a local lawyer or licensed auditor early. Early advice typically prevents delays, avoids penalties, and keeps your company compliant and investor ready.
