Every year, thousands of Spanish family businesses face the same unspoken dilemma: how can they transfer the business to the next generation without jeopardising its viability or the assets built over decades?
The answer is no longer merely a matter of will or family trust. Since 1 July 2026, the Community of Madrid has had a renewed tax framework (Law 3/2026 on Support for Family Businesses), which raises to 99% the reduction applicable to Inheritance and Gift Tax for such transfers. This is complemented by Supreme Court case law increasingly favourable to business continuity, which in 2025 decisively eased the requirements for accessing these benefits.
The result is an exceptional window of tax opportunity. But it is also a process which, if poorly executed, can give rise to contingencies that may take years to resolve before the tax authorities or the courts.
At Godia Tax Advisors, we have spent more than two decades assisting Madrid-based business families through this process. This guide sets out, in our experience, what makes the difference between a well-executed generational transition and one that ends in conflict or an unexpected tax assessment.
What Exactly Is Generational Succession in a Family Business?
Generational succession is the process by which one generation transfers ownership, control and management of a family business to the next. Although these three elements are often confused in everyday language, they should be separated precisely from a legal and tax perspective, because each follows its own logic and uses different instruments:
- Ownership succession: who will own the shares or stock.
- Management succession: who will assume executive leadership and day-to-day decision-making.
- Business and family governance: how relationships between shareholders are structured when several family branches coexist, or when some members own the business but do not work in it.
Confusing these three dimensions is, in our experience, the most common underlying mistake. Being an heir does not mean being prepared to lead. And the person who leads best is not always the one who should hold the largest percentage of the capital.
Why Generational Succession Cannot Be Improvised
The family business combines two dynamics that rarely move at the same pace: the business, which requires profitability, professionalisation and agile decision-making; and the family, which brings personal ties, succession expectations and, often, different financial interests among its members.
While the founder remains at the helm, these tensions are usually kept under control. The balance changes (sometimes abruptly) when there is a retirement, death, sudden incapacity or, simply, the arrival of a new generation with its own ideas about the business.
The conflicts we most frequently observe in our practice include:
- Family members who join the business without clearly defined duties or compensation.
- Shareholders who own capital but do not work in the company, with dividend expectations different from those who do.
- Disagreements over the valuation of shares at the time of transfer.
- Deadlocks between family branches with balanced holdings and no clear majority for decision-making.
Advance planning makes it possible to anticipate these situations, instead of dealing with them once they have become open conflicts, at which point the available solutions are invariably worse and more costly.
The Family Protocol: The Backbone of Succession
The family protocol is the central instrument for organising relations between family, ownership and business before the succession takes place. It is not a contract fully effective against third parties, but it does set out the family consensus that must later be reflected in the articles of association, shareholder agreements and testamentary provisions.
A well-designed protocol regulates, among other matters:
- The training and experience requirements for family members to join the business.
- Remuneration and dividend distribution policy.
- Composition and operation of the governing bodies.
- Mechanisms for transferring shares and voluntary shareholder exits.
- Procedures for resolving conflicts among family members.
The usual mistake is not failing to have a protocol, but having one that was never coordinated with the articles of association or tax planning. A protocol not reflected in the articles is, in practice, a statement of intent with no real binding force.
Review the Articles of Association Before Initiating Any Transfer
It is common for family businesses, after twenty or thirty years of activity, to retain the same articles of association with which they were incorporated, drafted for an ownership structure and number of shareholders that no longer exist.
Before beginning the succession, it is advisable to review specifically:
Share transfer rules. What restrictions or prior authorisation mechanisms exist to prevent, within the limits of Article 107 of the Spanish Companies Act, third parties outside the family from entering the company.
Transfers mortis causa. What happens when a shareholder dies and their shares become part of the estate; whether the articles provide a pre-emptive acquisition right in favour of the other shareholders or the company.
Enhanced majorities. When capital is divided among several descendants or family branches, certain strategic decisions (capital increases, structural changes, significant borrowing) may require majorities above the statutory thresholds.
Management body. A sole director, suitable in the first generation, often ceases to be appropriate when several family shareholders coexist. Moving towards a board of directors, with or without independent directors, is usually the most robust solution.
Should All Children Receive Equal Shares?
This is probably the most delicate question in the entire process. Economic equality among heirs does not legally require that everyone receive exactly the same assets.
It is common for one child to have built their entire career within the company and be destined to lead it, while another has neither the calling nor the intention to participate in the business. Automatically dividing the capital equally in these cases often creates governance and decision-making problems in the medium term.
The solution lies in analysing the family wealth as a whole (shares, property, financial investments and liquidity) in order to design a distribution that protects the economic rights of all heirs without compromising the company’s shareholding stability. This can be structured, for example, through non-voting shares, compensatory cash payments, or allocating other family assets to the person who does not join the business. All of this must remain within the framework imposed by succession law, including the rules on reserved shares.
Taxation of Generational Succession: What Changed in 2026
This is by far the area where poor planning is most costly. The transfer of shares in a family business simultaneously affects Inheritance and Gift Tax (ISD), Wealth Tax (IP) and, depending on how the transaction is structured, the transferor’s Personal Income Tax (IRPF).
The 99% Reduction in Madrid Since July 2026
Law 3/2026 of 30 June on Support for Family Businesses raises from 95% to 99% the reduction in the ISD taxable base applicable to the acquisition, whether mortis causa or inter vivos, of individual businesses, professional practices and shares in family entities. The law entered into force on 1 July 2026 and applies to taxable events accruing from that date.
The difference is not symbolic. On a taxable base of €5,000,000, increasing the reduction from 95% to 99% cuts the theoretical tax bill by more than 80%. For families considering the optimal time to carry out the transfer, this regulatory change alone may justify bringing forward or postponing an operation already planned.
It is also important to bear in mind that this regional reduction is incompatible with the equivalent state reduction, and maintaining it requires compliance with a minimum holding-period requirement: if it is breached, the beneficiary must self-assess the portion of tax not paid, plus late-payment interest, within 30 working days of the breach.
Economic Activity in Companies Engaged in Property Rental
For companies whose activity consists of renting out property, applying certain tax benefits linked to family businesses requires careful analysis of whether the entity actually carries out an economic activity for tax purposes.
As a general rule, Spanish Personal Income Tax regulations consider property rental an economic activity when at least one employee with an employment contract works full-time to organise it.
This requirement is particularly important when the family structure includes holding companies or entities engaged in real-estate operations, since meeting it may be decisive in accessing certain benefits under Wealth Tax and Inheritance and Gift Tax.
Therefore, before carrying out a share transfer, it is advisable to review not only the formal existence of the employment relationship, but also the company’s structure, activity and asset composition, as well as overall compliance with the other requirements set out in the family business regulations.
Corporate Reorganisations: The FEAC Regime
When the structure of the family group needs to be reorganised before succession (for example, by creating a holding company or separating certain business lines), the transaction may qualify for the special tax-neutrality regime for mergers, demergers, asset contributions and exchanges of securities (the FEAC regime, Articles 76 et seq. of the Spanish Corporate Income Tax Law), provided that there is a valid business purpose other than mere tax saving. In our experience, analysing this business rationale in advance is where most restructuring operations end up being challenged by the Tax Inspectorate.
Lifetime Gifts or Inheritance: There Is No Universal Answer
The lifetime gift allows the next generation to be brought into the business progressively while the founder can supervise the transition. Inheritance may be preferable when the founder needs to retain control, income or availability of their assets.
The comparison should not be limited to ISD. It is also necessary to assess the transferor’s IRPF taxation (a gift of shares with latent capital gains may generate a capital gain unless the non-taxation under Article 33.3.c of the LIRPF applies to transfers meeting the family-business requirements), each family member’s wealth situation, tax residence and the applicable regional rules. The cheapest tax option in the short term is not always the most appropriate from the perspective of wealth and business continuity over a ten-year horizon.
An Illustrative Case
A family with a holding company grouping an operating business and several rented properties was considering gifting its shares to three children, one of whom was already part of management. The preliminary analysis made it possible to verify that the requirements for the rental activity to qualify as an economic activity for tax purposes were met; apply, where appropriate, the 99% reduction provided by Madrid’s regional legislation; and design a differentiated distribution of shares, offset by other family assets, to preserve economic balance among the heirs without compromising the company’s future governance.
Every family structure is different, and this example does not replace an individualised analysis: it illustrates how combining recent case law, regional legislation and wealth planning can transform the cost and risk of a transaction.
Professionalising Management: Succession Does Not End with the Transfer
The continuity of the business depends on the next generation being prepared to assume responsibility. Establishing objective criteria for joining the company (specific training, prior professional experience, clear definition of duties, remuneration policy consistent with the market) does not distance the family from the business: it ensures that management follows business rather than exclusively family criteria. In larger structures, bringing in external executives or independent directors often strengthens this transition.
When Should Succession Planning Begin?
When there is still time to make decisions. Waiting until retirement or a health problem arises drastically reduces the alternatives available. Early planning makes it possible to study different scenarios, review the applicable tax treatment, adapt the articles of association, prepare the family protocol, reorganise the corporate structure where necessary, and carry out the transition progressively rather than as a one-off operation under pressure.
An Integrated Strategy, Not a Collection of Documents
Generational succession must be analysed across disciplines, coordinating succession law, corporate law, taxation and asset structure to answer four questions: who will own the business, who will run it, how will control be exercised, and how can assets be transferred with the greatest legal certainty and tax efficiency?
At Godia Tax Advisors, we advise Madrid-based companies and business families on designing and implementing generational succession processes, integrating tax, corporate, succession and wealth planning. We routinely work alongside our corporate restructuring and wealth and succession planning team to provide a complete view of each transaction.
Every family business has a different structure, wealth and family relationships. There are no standard solutions: planning must be adapted to each family’s objectives and the business’s economic reality.
