Introduction
A depreciation rate not applied to a machine worth CHF 80,000 represents up to CHF 6,400 in Vaud cantonal tax paid unnecessarily in a single fiscal year. An under-valued provision for debtors of CHF 50,000 produces the same result. SME accounting is not an administrative compliance exercise: it is the document that the Vaud Cantonal Tax Administration (AFC-VD) reads before any taxation or audit decision. This guide details the six technical points where your balance sheet directly affects your 2026 tax burden.
Which Chart of Accounts Should a Swiss SME Really Use?
Article 957 of the Code of Obligations (CO) sets the thresholds for accounting obligations. An SME whose annual turnover exceeds CHF 500,000 must maintain full commercial accounts including a balance sheet, income statement and notes. Below this threshold, a simple receipts and expenditure account suffices — but this choice carries an indirect tax cost.
The CO does not prescribe a standardised chart of accounts. Two frameworks coexist for Swiss SMEs: the Code of Obligations alone (CO-only) and Swiss GAAP FER (Swiss GAAP Recommended Accounting and Reporting Rules). Swiss GAAP FER is legally required for public interest entities and companies exceeding two of the following three thresholds over two consecutive financial years: total balance sheet of CHF 20 million, turnover of CHF 40 million, 250 full-time employees (art. 961 CO). Below these thresholds, FER 35 offers a simplified framework suited to small entities.
For a Vaud SME taxed under cantonal law, the choice of accounting framework directly influences the presentation of balance sheet items subject to capital tax (art. 67 LI-VD). A CO-only balance sheet allows greater latitude in the valuation of inventories and fixed assets; a FER balance sheet is more restrictive but more legible during an audit. The consistency between the chosen framework, the valuation methods declared in the notes, and the figures shown in the tax return is the first point an AFC-VD inspector verifies.
To understand the structural components of the balance sheet that underpin these choices, the elements detailed in our article on the accounting equation provide a useful frame of reference.
Depreciation: Which Rates Does the AFC Tolerate Without?
The AFC publishes a circular on depreciation rates accepted for tax purposes. These rates constitute the deductible ceiling without additional justification. The principal rates applicable to Vaud SMEs in 2026 are as follows:
- Office furniture and fittings: 40% (residual value, declining-balance method)
- IT equipment and software: 40%
- Industrial machinery and equipment: 25–40% depending on effective wear
- Passenger vehicles: 40%
- Commercial buildings: 4% (insured value, straight-line method)
- Goodwill: 40%
Failing to apply the maximum rate on an asset of CHF 30,000 in office furniture results in CHF 12,000 of excess taxable profit — equivalent to approximately CHF 2,400 in Vaud cantonal tax foregone in the 2026 financial year alone, applying a combined effective ICC/IFD [cantonal and communal tax/federal direct tax] rate of approximately 20% for a Vaud SME.
The declining-balance method is applied to the net book value at the beginning of the financial year. An asset acquired during the year is entitled to pro rata temporis depreciation only if the articles of association or internal directives explicitly provide for this — the AFC-VD verifies this point in the event of an audit. Additional depreciation (over-depreciation) is permitted if the effective economic loss in value can be documented.
According to the AFC circular on depreciation, the declining-balance rates accepted without individual justification reach 40% for IT equipment and office furniture, representing for a Vaud SME a direct lever for optimising the annual taxable base.
Provisions for Doubtful Debtors: How to Account for Them Without?
Article 63 of the Federal Act on Direct Federal Tax (LIFD) permits the deduction of provisions justified by commercial usage. For debtors, the AFC's practice distinguishes three levels.
First level: the lump-sum provision accepted without individual justification. A provision for doubtful debtors of 5% on the balance of Swiss debtors and 10% on the balance of foreign debtors is accepted for tax purposes without file-by-file documentation. For an SME with CHF 400,000 in Swiss debtors and CHF 100,000 in foreign debtors, this represents CHF 30,000 of deductible provision — equivalent to approximately CHF 6,000 in tax avoided in Vaud.
Second level: individual provisions. Beyond the lump-sum rates, every franc provisioned must be justified by an individual file: an unanswered reminder letter, a documented commercial dispute, or the opening of debt-enforcement proceedings (LP [Loi fédérale sur la poursuite pour dettes et la faillite — Federal Act on Debt Enforcement and Bankruptcy]). The AFC-VD systematically claws back individual provisions not supported by dated documentation.
Third level: related-party debtors. Any provision on a receivable from a shareholder, a director or a company within the same group is subject to thorough scrutiny. The AFC-VD then applies the tax triangle doctrine and may reclassify the provision as a monetary benefit (art. 58 para. 1 let. b LIFD), triggering a tax reassessment accompanied by a withholding tax surcharge of 35%.
The year-end accounts must show each provision in a separate monitoring schedule, including the calculation basis, the rate applied and the reference to the supporting file. This schedule is the first document requested during a cantonal tax audit relating to receivables.
Shareholder-Director's Salary: What Amount Should the Accounts?
The salary paid to a shareholder-director is deductible from the company's taxable profit only if it corresponds to what an unrelated third party would receive for the same position under comparable market conditions. This so-called "arm's length" principle derives from article 58 para. 1 let. b LIFD and article 24 para. 1 LI-VD.
The AFC-VD regularly challenges remuneration below CHF 80,000 per year for a full-time managing director in a profitable Vaud SME. The tax reassessment then covers the portion deemed insufficient: if market rates justify CHF 120,000 and the accounts record CHF 60,000, the CHF 60,000 difference is potentially reclassified as a concealed dividend, taxed at the shareholder level.
The symmetrical situation is also monitored: an excessive salary artificially reduces the company's profit. The AFC-VD relies on sectoral salary data (OFS [Office fédéral de la statistique — Federal Statistical Office] surveys, SwissSalary data) to establish the reference remuneration. In Geneva, the vigilance threshold for a managing director has historically been higher, at around CHF 140,000–180,000 depending on the sector.
SME accounting must therefore reflect a salary documented by a job description, an external salary benchmarking exercise and a formal decision of the board of directors. These three documents constitute the primary defence in the event of an audit. The absence of any one of them is sufficient to undermine the deductibility.
Annual SME Year-End: Which Accounting Entries Generate a Tax Saving?
31 December is the last opportunity to record in the balance sheet charges that reduce the taxable base for the current financial year. Four items must be examined systematically.
First item: additional depreciation. If fixed assets have suffered documented economic impairment (technological obsolescence, market decline), additional depreciation may be recorded before year-end, beyond the standard AFC rates, provided it is accompanied by an explanatory note appended to the balance sheet.
Second item: provisions for future charges. Provisions for warranties, ongoing litigation or planned renovations are permitted if they correspond to a probable obligation at the balance sheet date (art. 960e CO). A provision for a commercial dispute with a client, based on correspondence exchanged before 31 December, may be recognised and deducted for the 2026 financial year.
Third item: accruals and deferrals. Prepaid expenses (rent, insurance premiums) and deferred income must be identified with precision. An error of CHF 20,000 in accruals represents approximately CHF 4,000 in tax incorrectly allocated between two financial years.
Fourth item: bad debts. An irrecoverable receivable recognised before 31 December may be written off directly against the current year's results, without passing through a provision. The required evidence is the formal closure of the enforcement proceedings (certificate of shortfall [acte de défaut de biens]) or a signed waiver agreement.
A detailed analysis of the financial indicators to monitor before year-end is set out in our article on financial report examples for Swiss SMEs.
When Does an SME's Internal Accounting Become a Red Flag?
The AFC-VD does not conduct random audits. Files are selected on the basis of quantitative indicators extracted from tax returns and submitted balance sheets. Being aware of these indicators makes it possible to identify risk areas in one's own accounting.
First indicator: the gap between the accounting profit and the declared taxable profit. A discrepancy of more than 15–20% without detailed explanation in the notes generates a formal request for information. This discrepancy typically arises from undocumented add-backs or contestable deductions.
Second indicator: the growth of the "other charges" line item. An "other operating charges" item representing more than 8–10% of turnover attracts attention, particularly if its movement is not linear from one financial year to the next.
Third indicator: the ratio of loans from shareholders to equity. Beyond a certain ratio, the AFC-VD applies the thin capitalisation rules (AFC circular no. 6) and may reclassify a portion of the interest paid as a dividend. For 2026, the interest rates accepted on shareholder loans are published annually by the AFC.
Fourth indicator: inconsistency between the VAT turnover declared to the central AFC and the revenue recognised in the cantonal income statement. The AFC-VD has systematically cross-referenced these two sources since the introduction of automatic inter-administration data exchange.
Fifth indicator: movement in equity not explained by the year's result and documented distributions. Any unexplained movement exceeding CHF 50,000 is liable to trigger a reconciliation request.
Maintaining rigorous SME accounting, with comprehensive explanatory notes and balance-sheet-to-tax-return reconciliation schedules, is the technical response to each of these five points.
Conclusion
Every line item in a Vaud SME's balance sheet produces a calculable tax effect: a depreciation rate not applied, a lump-sum provision not established, a poorly calibrated director's salary or a year-end close without precise accruals translate into tax amounts paid without legal basis or into a quantifiable risk of tax reassessment.

FAQ
Below CHF 500,000 in annual turnover, article 957 CO permits simplified accounting: a receipts and expenditure account and a statement of net assets are sufficient. However, this option reduces the fiscal legibility of the file and limits the ability to justify provisions and depreciation during an AFC-VD audit.
