Swiss company law imposes financial reporting obligations on every legal entity. The scope of those obligations depends on the size of the company, its legal form, and whether it has public interest or is part of a group. Understanding exactly what your company is required to produce, and what it is not required to produce but should produce anyway for management purposes, helps the finance function allocate effort correctly and avoid both under-compliance and unnecessary over-investment in statutory reporting.

The financial reporting obligations for Swiss companies are governed primarily by articles 957 to 963b of the Obligationenrecht (OR), as updated by the accounting reform that came into force in 2013 and was further revised in subsequent years.

The OR establishes a tiered system based on company size, with progressively more demanding requirements as companies grow.

Tier 1: Simple bookkeeping (einfache Buchführung). Individual companies and partnerships with annual revenue below CHF 500K are required only to maintain records of income, expenses, and assets. No formal double-entry accounts are required. This tier applies to sole traders and small partnerships only, not to legal entities (AG or GmbH).

Tier 2: Double-entry accounting with annual accounts. All legal entities (AG, GmbH, associations above CHF 100K revenue) are required to maintain proper double-entry bookkeeping and produce annual accounts consisting of a balance sheet (Bilanz), income statement (Erfolgsrechnung), and notes (Anhang). This is the minimum standard for any Swiss AG or GmbH.

The notes are often underestimated. OR Article 959c requires specific disclosures including the accounting principles applied, the basis for asset valuation, particulars of long-term interest-bearing liabilities, number of full-time equivalent employees, and information on related party transactions. Many SMEs file notes that are superficial or incomplete, which creates audit risk if the statutory accounts are subject to review.

Tier 3: Extended requirements for larger companies. Companies that exceed two of the three thresholds (CHF 20M balance sheet total, CHF 40M net revenue, 250 full-time employees) must produce a cash flow statement and a management report (Lagebericht) in addition to the balance sheet and income statement. The cash flow statement is a standard direct or indirect method statement. The Lagebericht is a narrative report covering the business development, current financial position, and material risks.

Many Swiss controllers are surprised to learn that their company is required to produce a cash flow statement. The threshold is not as high as many assume: a company with CHF 40M revenue and a modest balance sheet meets the threshold on revenue alone.

Audit Requirements

The audit obligations under the OR are separate from the accounting obligations and are also size-dependent.

Ordinary audit (ordentliche Revision). Required for publicly held companies, banking and insurance companies, and companies that exceed two of the three thresholds noted above. Must be conducted by a licensed audit firm (Revisionsunternehmen) accredited by the Eidgenössisches Revisionsaufsichtsorgan (RAB).

Limited audit (eingeschränkte Revision). Required for companies that exceed two of three lower thresholds (CHF 10M balance sheet, CHF 20M revenue, 50 employees) but do not reach the ordinary audit threshold. Can be conducted by a licensed auditor rather than a full audit firm. Less extensive than the ordinary audit: the auditor provides limited assurance rather than a positive opinion.

Opting out of audit entirely. Companies below the limited audit threshold and with fewer than 10 full-time employees can, by unanimous shareholder vote, opt out of the audit requirement entirely (Opting-out). The accounts still need to be prepared and maintained, but no external review is required. Many small Swiss companies have exercised this option.

The audit requirement, once triggered, is not optional. A company that exceeds the threshold but has not engaged an auditor is in breach of the OR. The statutory auditor is appointed by the general meeting of shareholders, and the appointment must be renewed annually.

Valuation Principles Under OR

Swiss OR accounting follows specific valuation principles that are more conservative than IFRS in several respects. These principles matter for the management accountant because they produce statutory accounts that differ from management accounts in ways that need to be understood and documented.

Lower of cost or market for assets. OR requires assets to be valued at the lower of cost and net realisable value. Unrealised gains on financial assets are not recognised in OR statutory accounts (unlike IFRS fair value accounting). A portfolio of equity investments that has appreciated significantly will appear on the balance sheet at historical cost, not at current value.

Accelerated depreciation is permitted. OR allows companies to depreciate assets faster than their economic life would justify, which produces lower net asset values and lower taxable income. The result is statutory balance sheets that may significantly understate the true economic value of the asset base relative to IFRS.

Silent reserves are permitted. OR explicitly permits companies to maintain undisclosed reserves (stille Reserven) by undervaluing assets or overvaluing liabilities. This is a uniquely Swiss accounting feature that has no equivalent in IFRS or US GAAP. The existence of silent reserves means the OR statutory balance sheet may not represent the economic net asset value of the business, which matters for valuation discussions and management analysis.

Prudence principle. OR accounting is governed by a strong prudence principle: when in doubt, understate assets and overstate liabilities. This is the opposite orientation from IFRS, which aims for neutral representation. The result is that OR profit is typically more conservative than IFRS profit, and OR equity is typically lower than IFRS equity for the same business.

The Gap Between OR Accounts and Management Accounts

For controllers working with companies that produce both OR statutory accounts and management accounts, understanding the sources of difference between the two is important for both internal analysis and external communication.

Common sources of difference:

Depreciation timing. OR may use accelerated depreciation for tax purposes. Management accounts typically use straight-line depreciation over the economic life of the asset. The difference appears as a higher depreciation charge in the statutory accounts in early years, followed by lower depreciation in later years.

Provision levels. OR conservatism often produces higher provisions than management accounting requires. A provision for doubtful receivables at 5 percent of all outstanding receivables regardless of ageing may be appropriate for statutory purposes but overstates the likely economic loss for management reporting purposes.

Silent reserves. If the company is maintaining silent reserves through undervalued inventory or understated asset values, the management accounts should reflect the economic values rather than the conservative OR values.

Revenue recognition. In rare cases, the timing of revenue recognition may differ between OR accounts and management accounts, particularly for long-term contracts or milestone-based projects.

Documenting these differences in a reconciliation schedule is both a controller best practice and useful preparation for any external transaction process where buyers or investors will compare OR accounts to management accounts and ask about the reconciling items.

What Most Companies Are Missing

In practice, the most common OR compliance gap in Swiss SMEs is not the failure to produce accounts at all, but the quality and completeness of the notes to the accounts. Many companies file minimal notes that technically satisfy the OR requirements but fall short of what a well-governed company should disclose.

The second most common gap is the failure to produce a cash flow statement for companies that have crossed the relevant threshold, often because nobody has checked whether the threshold has been exceeded in recent years as the business has grown.

The third is the Lagebericht: the narrative management report required for larger companies. This document, when done well, provides a coherent narrative about the business that complements the numbers and serves both the audit process and the banking relationship.
