For many Swiss SMEs, the year-end closing is the most stressful phase of the year. Yet with the right preparation, the effort can be reduced considerably. This checklist gives you and your fiduciary (Treuhänder) a structured basis for handling the 2026 closing efficiently, correctly and on time.
The annual financial statements under the Code of Obligations (OR) serve not only the tax authority, but are the most important control instrument for managing your business. They show whether your business model is profitable, where capital is tied up and how liquid you are for the coming months. Carefully prepared financial statements are the basis for discussions with banks, investment decisions and tax optimisation.
The most common mistake: the accounts are neglected during the year and caught up on in a major effort in December. This leads to errors and costs time. Make sure that all documents have been booked by October and that the bank and cash accounts reconcile.
Review all outstanding receivables. Uncollectible receivables must be written down or written off. Prepare an accounts receivable list with due dates and an assessment of collectability. Receivables older than 90 days require particular scrutiny.
If your SME holds stock, the stock must be evidenced by an inventory or in another way (Art. 958c para. 2 OR); for warehouse stock, a physical stock count as at the reporting date is the usual approach. Plan the stocktaking dates early and train the employees responsible. If the realisable value less costs still to be incurred is lower than the acquisition or production cost, this lower value applies (Art. 960c OR).
Provisions for known future liabilities, for example warranty obligations, litigation risks or bonus payments, must be booked before the closing. Accruals and deferrals must likewise be made: prepaid services (prepaid expenses) and expenses not yet invoiced (accrued expenses) are allocated to the correct period.
Check whether all new acquisitions of the year are recorded in the fixed asset register. Define the useful life according to rates recognised for tax purposes or according to economic reality. In Switzerland, declining balance depreciation is permitted for tax purposes and sensible in many sectors. The following maximum rates apply according to Information Sheet A of the Federal Tax Administration (ESTV) (declining balance, calculated on book value):
| Asset category | Declining balance (on book value) |
|---|---|
| Business furniture, workshop and warehouse equipment | 25 % |
| Apparatus and machinery for production purposes | 30 % |
| Motor vehicles of all kinds | 40 % |
| Office machines, IT equipment, software | 40 % |
| Commercial, office and bank buildings (building alone) | 4 % |
| Commercial, office and bank buildings (building and land together) | 3 % |
Source: ESTV Information Sheet A/1995 (business enterprises). For straight-line depreciation (on acquisition cost), half the rates apply. Higher immediate write-offs may be permitted at cantonal level.
For limited liability companies (GmbH) and companies limited by shares (AG), the capital structure must be documented precisely. Shareholder loans are viewed critically by the tax authorities, particularly if the interest rate does not reflect the market. According to the ESTV circular for 2026, a minimum interest rate of 0.75 percent applies to loans in Swiss francs from equity to shareholders or related parties. Conversely, for loans from shareholders to the company (operating loans) up to CHF 1 million, maximum interest rates of 3.5 percent apply for trading and manufacturing companies and 3.0 percent for holding and asset management companies (ESTV circular of 29 January 2026). Anyone breaching these ranges risks a constructive dividend (geldwerte Leistung) with an add-back and withholding tax consequences.
The year-end closing is the most important time for tax optimisation. Measures taken after the closing date only take effect in the following year. Check together with your fiduciary:
A well-prepared dossier saves your fiduciary time and you costs. Provide the following documents:
The annual financial statements must be submitted to the shareholders or the general meeting within six months of the closing date. For most SMEs with 31 December as the closing date, this means: the ordinary general meeting takes place by the end of June. The tax return depends on the canton, but is often due 9 to 12 months after the closing.
Bilanzo is the local AI bookkeeping agent that keeps your existing accounting software up to date all year round: it captures documents, suggests entries and books them directly in your usual solution (for example bexio). As a result, the basis for the closing, that is the balance sheet, income statement and notes under Art. 959c OR, is clean and complete at all times, instead of in a December rush. Your software produces the reports as usual, and you and your fiduciary gain time for what matters: the business analysis of the results.
