Ref: 04.22DISSOLVING HIDDEN RESERVES: THE TAX TRIGGER

How to dissolve hidden reserves in Switzerland?

Alain Walder, M.A. HSG · ValIndex|Published January 2026

Official Position

Dissolving hidden reserves (Auflösung stiller Reserven) converts unreported value into visible profit, triggering corporate income tax. The strategic question is WHEN and HOW to release them — forced dissolution (sale, restructuring) vs. voluntary dissolution (tax optimization, exit preparation). ### Technical Explanation #### What Are Hidden Reserves? Hidden reserves exist when an asset's book value is below its true economic value: * Inventory: Carried at acquisition cost vs. current replacement value * Machinery: Fully depreciated on books but still productive and valuable * Real estate: Historical cost vs. current market value (often the largest reserve) * Provisions: Over-provisioned liabilities (warranty, maintenance) beyond actual need * Undervalued receivables: Conservative write-downs on performing accounts #### Dissolution Triggers 1. Asset Sale: Selling an asset above book value forces recognition of the gain 2. Revaluation: Adjusting book values upward (rare under Swiss GAAP) 3. Company Sale (Asset Deal): All hidden reserves realized at once 4. Merger/Restructuring: Swiss Merger Act (FusG) allows tax-neutral transfers in qualifying reorganizations 5. Liquidation: All assets sold, all reserves dissolved #### Tax Consequences Dissolved hidden reserves = taxable profit at the corporate level: * Federal corporate income tax: 8.5% (effective ~7.83%) * Cantonal/municipal tax: varies (5-15%) * Combined rate: typically 12-18% * Capital gains on real estate may trigger separate Grundstückgewinnsteuer #### Strategic Dissolution Approaches * Pre-sale normalization: Selectively dissolve reserves in inventory and provisions to boost reported EBITDA, accept the tax cost now to achieve a higher exit multiple * Tax-neutral restructuring: Use FusG Art. 19 to transfer assets to a new entity without immediate tax (condition: tax liability transfers too) * Staggered dissolution: Spread recognition over multiple years to stay in lower tax brackets * Offsetting with losses: Time dissolution to coincide with available tax loss carry-forwards (7-year limit in most cantons)

Rationale & Context

Every franc of hidden reserves has a dual identity: a tax liability waiting to happen, and a valuation opportunity. The art is managing the timing. In a share deal, the buyer acquires the hidden reserves without triggering dissolution — but may demand a price discount for the latent tax liability. In an asset deal, dissolution is immediate and the tax cost is borne by the selling entity. We calculate the 'tax cost of dissolution' for every major asset category and present buyers with a clear analysis: this is the value, this is the tax cost, and this is why the share deal structure benefits both parties.
