Strategic Context
Complete guide to Corporate Restructuring and M&A Transactions in Spain. Learn about due diligence, SPA negotiation, FEAC tax neutrality, and FDI screening rules.Cross-border M&A in Spain requires specialized legal and tax structuring to minimize exposure, protect yields, and satisfy regulatory requirements.
Critical Phases
Transaction success relies heavily on rigorous multi-disciplinary Due Diligence and precise Share Purchase Agreement (SPA) drafting.
Tax Optimization
Qualifying for the Special Tax Scheme for Mergers and Demergers (FEAC) is crucial to achieve corporate tax neutrality and defer capital gains.
FDI Controls
Spain maintains strict Foreign Direct Investment (FDI) screening rules for non-EU/EFTA investors targeting strategic sectors, often requiring prior Cabinet approval.
Spain remains a premier entry point for international corporate expansion, private equity deployments, and institutional investment across Europe. Whether driven by market consolidation, vertical integration, or strategic asset acquisition, executing Mergers & Acquisitions (M&A) or Corporate Restructurings in the Spanish jurisdiction demands an integrated legal and tax approach.
At LegalTax, we advise international corporations, private equity firms, and family offices through every phase of their corporate transactions in Spain. Below is an authoritative breakdown of the legal, tax, and regulatory imperatives governing successful transactions in 2026.
Key Stages of Corporate Restructuring and M&A Transactions in Spain
1. Preliminary Phase: NDA & Letter of Intent (LOI)
Prior to exchanging confidential commercial data, parties execute a binding Non-Disclosure Agreement (NDA). This is followed by a Letter of Intent (LOI) or Term Sheet, which sets out the deal architecture, key economic terms, valuation parameters, exclusivity periods, and condition precedents required before entering formal agreements.
2. Legal, Tax, and Labor Due Diligence
Due diligence forms the bedrock of risk mitigation. The buyer’s legal team conducts an in-depth audit of the target company across three key verticals:
- Tax Liabilities: Unexpired tax years, transfer pricing documentation, pending tax audits, and VAT/Corporate Tax compliance.
- Employment & Labor Law: Senior management contracts (including C-suite covenants and Beckham Law implications), collective bargaining agreements, and social security compliance.
- Corporate & Commercial Matters: Material contracts (change-of-control provisions), regulatory licenses, intellectual property titles, real estate leases, and active litigation exposure.
3. Drafting the Share Purchase Agreement (SPA)
The Share Purchase Agreement (SPA) or Asset Purchase Agreement (APA) allocates liability between buyer and seller. Key legal mechanics negotiated include:
- Price Adjustment Mechanisms: Completion Accounts vs. Locked Box structures.
- Representations & Warranties (R&W): Tailored indemnities backed by escrow accounts or W&I (Warranty & Indemnity) insurance.
- Liability Caps: De minimis, baskets, and overall indemnity caps (Caps).
4. Signing & Closing
In complex transactions, Signing and Closing do not occur simultaneously. Intervening conditions precedent often include antitrust clearances from the Spanish National Markets and Competition Commission (CNMC) or regulatory FDI authorizations.

Corporate Restructuring Strategies: Mergers, Demergers & Spin-offs
Restructuring an existing corporate structure is often necessary prior to an acquisition, to isolate risk, or to separate distinct business units.
Mergers, Demergers, and Asset Contributions
Under Spanish Corporate Law (governed by the Structural Modifications framework), companies can consolidate assets (Mergers) or divide business lines (Demergers or Spin-offs). Separating real estate holdings from operational business entities is a common restructuring mechanism prior to entering an M&A process.
The Tax Neutrality Scheme (FEAC Regime)
Corporate restructurings in Spain can be executed without immediate tax crystallization by applying the Special Tax Scheme for Mergers, Demergers, Asset Contributions, and Security Exchanges (FEAC) regulated under the Spanish Corporate Income Tax Act.
- Tax Deferral: Allows the deferral of capital gains generated during asset or share transfers.
- Valid Economic Reason Test: To qualify, the transaction must be motivated by legitimate economic reasons (such as operational efficiency or structural simplification) rather than purely tax avoidance. Proving this economic rationale to the Spanish Tax Agency (Agencia Tributaria) is a core legal requirement.

Foreign Direct Investment (FDI) Screening in Spain
Spain enforces screening mechanisms for Foreign Direct Investment (FDI) originating from non-EU and non-EFTA entities (or EU entities ultimately controlled by non-EU shareholders).
Strategic Sectors Subject to Prior Authorization
An FDI authorization from the Spanish Cabinet (Consejo de Ministros) is mandatory if an investor acquires 10% or more of a Spanish company operating in sensitive or strategic sectors, including:
- Critical infrastructure (energy, transport, communications).
- Dual-use technology and cybersecurity.
- Healthcare and biotechnology.
- Media and strategic data infrastructure.
Executing a transaction without required FDI authorization renders the transaction legally void and exposes the buyer to significant administrative penalties.
