Why deal structure matters more than price
Acquiring a competitor, strategic supplier or key customer is a common growth lever among Swiss SMEs. The purchase price captures attention, but the legal structure of the transaction — asset deal (acquisition of selected individual assets and liabilities) or share deal (acquisition of the target company's shares or equity interests) — largely determines the accounting outcome, tax burden and exposure to hidden risks.
In an asset deal, the buyer selects what enters the balance sheet and which debts to assume, often via a new acquisition vehicle or direct integration into its own accounts. In a share deal, the buyer acquires the legal entity in its entirety: contracts, staff, pending litigation and unquantified liabilities remain with the entity, which continues to exist with the same legal identity.
For entrepreneurs, CFOs and trustees, the choice is not purely legal: it affects the VAT tax base, stamp duty, future depreciation, treatment of hidden reserves and obligations towards OASI (AVS), occupational pension (LPP) and tax authorities. This guide compares the two approaches in the context of Swiss SMEs, with reference to current federal law and FER accounting practices.
Asset deal and share deal: what actually changes
Asset deal — selective acquisition of assets
The buyer enters into a business asset purchase agreement covering operating assets (fixed assets, inventory, receivables, contracts, trademarks, customer base) and, if agreed, specific liabilities. The selling company remains in existence and liquidates any residual assets or is dissolved at a later stage.
Typical for smaller GmbHs and AGs when the aim is to avoid inheriting uncertain liabilities or when the target has complex balance sheet situations (real estate, leasing contracts, cross-guarantees).
Share deal — acquisition of the equity interest
The buyer acquires the equity interests (GmbH) or shares (AG) of the target company. There is no direct transfer of individual assets: ownership of the participation changes. The business continues with the same contracts, employees and registry numbers.
Preferred when value lies in the intangible customer portfolio, licences or operational continuity, and when seller and buyer want to minimise administrative disruption and notifications to customers and suppliers.
Comparative table: asset deal vs share deal
Summary of the main decision criteria for an acquisition among Swiss SMEs:
| Criterion | Asset deal | Share deal |
|---|---|---|
| Subject matter of the contract | Selected assets, contracts and liabilities | Equity interests or shares of the target company |
| Legal continuity of the target | The selling company remains (then possibly liquidated) | The target company continues with new ownership |
| Hidden liabilities | Assumed only if expressly transferred and identified | Inherited in full with the company |
| Stamp duty (Umsatzabgabe) | Not due on transfer of operating assets; caution if securities are included | 0.15% (CH) / 0.3% (foreign) if a Swiss securities dealer is involved |
| VAT (MWST) | Relevant; notification procedure if transfer of a business (Art. 38 VAT Act) | Generally excluded from VAT (Art. 21 para. 2 VAT Act) |
| Tax on seller's corporate income | Capital gains realised and taxed on each asset transferred | Gain on the participation; possible reduction for qualified participations (Art. 69 LIFD) |
| Buyer's depreciation base | Revaluation at purchase price (step-up) | Target's historical book values unchanged |
| Hidden reserves (stille Reserven) | Realised and taxed by the seller | Remain on the target's balance sheet; indirect benefit for the buyer |
| Staff | Transfer if transfer of a business (Art. 333 CO); information/consultation (Art. 333a CO) | Employment contracts remain unchanged within the same company |
| Contractual complexity | High: asset schedule, third-party consents, warranty clauses for individual items | Share purchase agreement + corporate due diligence |
| Typical professional costs | CHF 15,000–40,000+ (notary, tax advisor, asset appraisal, employee consultation) | CHF 10,000–30,000+ (share notary, due diligence, stamp duty) |
Accounting treatment under Swiss standards (FER / Swiss GAAP FER)
The structure of the transaction changes how the buyer records the investment and future depreciation:
Asset deal — capitalisation at fair value
The buyer records each acquired asset at the agreed or estimated value (fair value). Tangible and intangible fixed assets can be depreciated on a higher base than the seller's historical values, generating a future tax benefit (greater depreciation deduction).
If the price exceeds the algebraic sum of the net book values acquired, goodwill arises, depreciable under the applicable FER rules. Inventory, receivables and payables must be reconciled with physical stock counts and receivables ageing analysis. In Accountex, recording each asset category separately facilitates post-acquisition monitoring and reconciliation with the purchase agreement.
Share deal — investment and consolidation
The buyer records an investment in the participation at acquisition cost. If it holds more than 50% or exercises control, consolidation applies: the target's financial statements are integrated into the group. Internal book values remain historical — there is no automatic step-up unless a subsequent merger is carried out.
Hidden reserves (undervalued assets, excessive provisions) remain on the target's balance sheet and are gradually realised through future profits at ordinary tax rates, or upon disposal of the underlying assets. For the buyer, this represents a potential economic benefit not immediately visible in the income statement.
Tax implications: VAT, stamp duty and profit tax
VAT — transfer of a business (Art. 38 VAT Act): In an asset deal structured as a transfer of a business or an autonomous part of a business, VAT-registered parties may apply the notification procedure (Meldeverfahren): tax is accounted for by the transferor and deducted by the acquirer, with a neutral cash flow effect if both are registered. If the requirements are not met (e.g. partial acquisition without functional autonomy), VAT at the 8.1% rate applies to taxable assets — a significant impact on the transaction's cash flow. Always verify with the FTA before closing.
Stamp duty on securities transactions: In a share deal, the securities transfer tax (Umsatzabgabe) of 0.15% on Swiss securities or 0.3% on foreign securities applies to the consideration (or market value if higher) if a Swiss securities dealer participates in the transaction; in direct transfers between private parties without a dealer, the tax may not be due. For an SME with modest nominal capital but high enterprise value, the impact generally remains limited relative to the total price, but should be calculated in the transaction business plan.
Corporate income and capital tax: A corporate seller in a share deal may benefit from the reduction for qualified participations (Art. 69 LIFD: participation ≥ 10% held for at least one year), taxing only the commercial portion of the capital gain. In an asset deal, each capital gain on individual assets is fully taxed at corporate level. For an individual seller holding shares, taxation occurs at the level of private capital gains on securities (varies by canton).
Cantonal real estate transfer taxes: If the transaction includes owned real estate, an asset deal generally triggers cantonal real estate capital gains tax and/or transfer duty. In a share deal where real estate is owned by the target, many cantons apply "change of control" rules — taxation as if a direct transfer had occurred. Cantonal analysis is essential.
Note — hidden reserves and step-up: In an asset deal, the seller pays tax on realised reserves, but the buyer obtains revalued assets. In a share deal, the seller may obtain more favourable tax terms, but the buyer does not obtain an accounting step-up. The negotiated price should reflect this trade-off, often subject to negotiation between the parties and their respective tax advisors.
Hidden risks: where exposure concentrates
Beyond price and tax, the structure of the transaction determines the residual risk profile after closing:
- 1
Undeclared tax and social security liabilities
In a share deal, retroactive VAT, OASI or LPP assessments hit the acquired company. Tax warranties and indemnities in the share purchase agreement are essential. In an asset deal, verify that no tax liability remains linked to the transferred assets (e.g. property with encumbrances or pending litigation).
- 2
Employee disputes and underfunded pension funds
Staff transfer in an asset deal triggers protection against dismissal for reason of transfer (Art. 333 CO). In a share deal, any underprovisioned pension liabilities remain on the balance sheet. Request an LPP actuarial appraisal and verify compliance with LPP and OPCC regulations.
- 3
Guarantees, sureties and off-balance sheet commitments
Guarantees issued in favour of third parties, bank sureties and purchase commitments not reflected on the balance sheet emerge during corporate due diligence. In an asset deal, explicitly exclude them from the perimeter; in a share deal, quantify them and negotiate holdback or escrow on the price.
- 4
Change-of-control clauses in commercial contracts
Strategic suppliers or customers may terminate in the event of a change of control. In a share deal, the risk is immediate; in an asset deal, contract transfer requires counterparty consent if contracts contain reservation or assignment prohibition clauses.
- 5
Inventory and receivables valuation differences
Obsolete inventory, uncollectible receivables or warranty products underestimated can erode the effective value of the acquisition. Provide for post-closing price adjustments (closing accounts mechanism) and specific warranties on work in progress and inventory.
When to prefer one structure over the other
Asset deal — favourable scenarios
- Target with uncertain liabilities, litigation or complex tax situations
- Desire for a tax step-up on acquired assets
- Partial acquisition (only one business unit, one retail outlet, one product line)
- Seller willing to tax capital gains and reduce the price accordingly
- Real estate to be acquired with separate revaluation and depreciation
Share deal — favourable scenarios
- Value tied to customer base, licences, certifications difficult to transfer individually
- Need for operational continuity without contractual disruption
- Target with significant hidden reserves and seller willing to offer a tax discount
- Fast transaction with lower administrative complexity at closing
- Corporate seller with a tax-advantaged qualified participation
Operational process and pre-closing checklist
An orderly SME acquisition requires coordination between the entrepreneur, trustee, lawyer and auditor:
- 1.Letter of intent (LOI): define indicative structure, price, exclusivity period and confidentiality clauses.
- 2.Due diligence: financial (3–5 financial statements, management reconciliation), tax (VAT, direct taxes, FTA verification), legal (contracts, intellectual property, litigation), social (LPP, collective agreements).
- 3.Comparative tax simulation: model both structures with the negotiated price to identify net proceeds for seller and buyer.
- 4.Definitive agreement: with representations & warranties, indemnities, conditions precedent (bank consents, competition authority if applicable, shareholder approval).
- 5.Closing and registrations: transfer of shares by notarial deed (GmbH) or assignment of shares; or asset schedule with possible employee consultation (Art. 333a CO) for transferred staff.
- 6.Accounting integration: chart of accounts mapping, opening of investment or fixed assets, VAT period alignment and first consolidated financial statements.
Managing the acquisition with Accountex
An acquisition generates a spike in accounting complexity: new fixed assets to depreciate, receivables to migrate, possible group consolidation and reconciliation between the purchase agreement and ledger entries. Accountex allows you to structure the chart of accounts for an acquisition vehicle or acquired subsidiary, track post-closing opening entries and monitor one-off transaction costs separately from operating expenses.
For trust companies assisting SMEs in M&A transactions, multi-entity and cost centre reporting facilitate board reporting during the first 12–24 months post-acquisition — a critical period for verifying synergies, staff integration and achievement of EBITDA targets promised in due diligence.
The choice between asset deal and share deal admits no universal answer: it depends on the risk profile, the parties' tax position and the nature of the assets acquired. Comparing both structures with concrete simulations before signing the LOI is the most effective defence against accounting and tax surprises after closing.
