Family Business

A family business is one in which one or more families hold a controlling ownership stake and exercise significant influence over its management or governance. In Spain, family businesses represent more than 85% of the business fabric and are characterised by the intertwining of family and corporate relationships, requiring specialised planning in the areas of succession, governance, and financing.

In practice

What Is a Family Business?

A family business is one in which one or several members of the same family hold a majority ownership stake and actively participate in its management or governance bodies (board of directors, shareholders’ meeting). There is no single legal definition in Spain, but the Instituto de la Empresa Familiar (IEF) and the European Union agree on the essential elements: family control of ownership, family influence over strategic direction, and the intention to pass the business on to the next generation.

Family businesses represent more than 85% of Spanish companies, generate around 60% of private GDP, and employ over 6.5 million people. Their strengths lie in long-term vision, team loyalty, and brand identification; their main risk lies in the blurring of family and business roles.

Key Aspects of Family Business Governance

Family Protocol A document regulating the relationship between the family and the company: access to employment for family members, dividend policy, exit mechanisms for shareholders, succession process in management and ownership. Although it is not legally binding by default, it can be elevated to a public deed to give it greater enforceability.

Professionalised Board of Directors The incorporation of independent external directors improves decision-making, brings market perspective, and reduces the influence of family conflicts on strategy. It is an essential step in the transition from the first to the second generation.

Family Council An informal or formal body that channels communication among family shareholders, separating the family agenda from the corporate agenda of the board of directors.

Succession Planning

  • Identification and training of the successor well in advance (minimum 5-10 years)
  • Use of tax instruments such as the 95% reduction in Inheritance and Gift Tax (ISD) for family business transfers
  • Technical valuation of the company to distribute the estate equitably
  • Shareholder syndication agreements to maintain family control after the transfer

Special Tax Implications

The family business tax regime allows a 95% reduction in Inheritance and Gift Tax (ISD) on transfers both on death and by gift, provided the requirements of the ISD Law are met: the activity must not be the management of wealth, the donor or deceased must hold a significant stake, and the acquirer must maintain the business for at least ten years. The exemption in Wealth Tax (IP) is linked to the same requirements.

Relevance for Businesses

Family business planning is not a luxury — it is a necessity to ensure the business survives beyond the first generation. According to the IEF, only 30% of family businesses reach the second generation and barely 12% reach the third. A well-designed family protocol, combined with an appropriate corporate structure and proactive tax planning, significantly increases the probability of a successful succession.

Frequently asked questions

Article 20.2.c of the Inheritance and Gift Tax Law (ISD) allows a 95% reduction in the taxable base when shares in a qualifying family business are transferred on death or by gift. The requirements include that the family holds a significant stake (at least 5% individually or 20% as a family group), that a family member exercises management functions in the company, and that the shares are exempt from Wealth Tax. The acquirer must maintain the shares and conditions for at least 10 years.
A family protocol is an agreement between family members governing the relationship between the family and the company — covering access to employment, dividend policy, share transfer rules, and succession. By default it is a private document without full legal enforceability, but it can be elevated to a public deed before a notary, which gives it stronger contractual force. Courts have increasingly upheld key provisions of properly drafted protocols.
According to the Instituto de la Empresa Familiar (IEF), only approximately 30% of Spanish family businesses successfully transition to the second generation, and barely 12% reach the third generation. The main causes of failure are lack of succession planning, governance conflicts between family branches, and underinvestment in professional management. Early, structured planning dramatically improves the odds of successful transition.
Most Spanish family businesses use a Sociedad Limitada (SL) as the operating vehicle, often with a holding SL above it to centralise ownership and separate different business lines. Shareholders' agreements (pactos parasociales) complement the articles of association to govern share transfers, tag-along rights, and governance disputes. As the family grows across generations, syndication agreements (sindicatos de voto) help maintain unified decision-making.
Best practice recommends beginning succession planning a minimum of 5 to 10 years before the intended transfer, both to prepare the successor and to optimise the tax structure. Many ISD reliefs require conditions to be in place well before the triggering event. Starting early also allows for a gradual handover of management responsibility, reducing operational risk and giving the successor time to build credibility with employees and clients.
