Succession in the family business: how to plan the handover

The family business is the backbone of Spain's productive fabric: it accounts for around 89% of all companies in the country, close to 1.1 million businesses, and it generates some 67% of private employment and 57% of private sector GDP (Instituto de la Empresa Familiar, 2024). Even so, the transition from one generation to the next remains the most fragile moment in its life cycle. A generational handover in a family business cannot be improvised: when it arrives with no plan behind it, it usually brings latent conflicts to the surface, along with tax pressure and a loss of value that in many cases could have been avoided.

For an established industrial SME, with revenue above half a million euros, a stable workforce and clients who depend on its continuity, planning the succession is not an emotional formality but a strategic decision that shapes the company's viability over the next decade. This guide explains how to approach the generational handover with method: from the family protocol and the succession plan through to the tax treatment under the Impuesto sobre Sucesiones y Donaciones (Spanish inheritance and gift tax), without losing sight of an alternative that more and more families are putting on the table, which is selling to a third party.

Why do so many generational handovers fail?

A generational handover brings together two planes that rarely move at the same speed: the family and the company. The family runs on affection, equal treatment between siblings and long-standing loyalties; the company runs on merit, competitiveness and profitability. When the two mix without clear rules, conflict follows. This is no minor issue: a very high proportion of family businesses face the generational change with no defined succession plan, which sharply reduces their odds of continuity (Instituto de la Empresa Familiar, 2024).

The most common friction points in a badly planned succession are easy to recognise:

• No prepared successor: confusing the right to inherit with the ability to lead. Not every descendant wants to run the company, and not every one of them should.
• Decision-making concentrated in the founder: personality-driven leadership that has never delegated and that leaves a gap nobody can fill overnight.
• No written rules: shares of power, dividends and responsibilities that are taken for granted until suddenly they are not.
• Tax consequences nobody saw coming: a transfer forced by a death can trigger a tax bill the family has made no provision for.

The good news is that almost all of these causes can be avoided with planning. A generational handover that works starts years before the actual change and rests on three pillars: a family protocol, a succession plan and a tax strategy.

What is the family protocol and why is it the first step?

The family protocol is the document that orders the relationship between the family and the company. It sets the rules of the game before problems appear: who can work in the business and on what terms, how decisions are taken, how dividends are shared, how shareholders come in and go out, and which governing bodies (family council, board of directors) hold it all together.

Under Spanish law, the family protocol has express statutory recognition. Royal Decree 171/2007 of 9 February governs the publicity of family protocols and allows them to be recorded at the commercial registry, which makes them enforceable against third parties where the family chooses that route (Royal Decree 171/2007, BOE). It is therefore not a mere statement of good intentions: designed properly and aligned with the articles of association and any shareholders' agreements, it becomes a legal instrument with real effects.

Is your family business facing the handover with no clear framework? At Tecnocim Innova we support handover, succession and business transfer deals, coordinating the strategic, financial and tax sides of the transition.

A useful family protocol is not a generic template. It has to be drafted out of real conversations with each member of the family, anticipate the uncomfortable scenarios (what happens if a child divorces, if a shareholder wants out, if nobody wants or is able to lead) and be reviewed regularly. In essence it is the social contract of the business family.

How do you plan the succession step by step?

Planning a generational handover is a process that runs over several years and is best broken into phases. Every company moves at its own pace, but the logical sequence is fairly universal.

1. Diagnosis and time horizon

The first step calls for honesty: is there a successor with both the will and the ability? In how many years does the outgoing generation want to retire? Is the company in a fit state to change hands? This diagnosis determines whether the natural route is family succession or whether other options, including a sale, deserve a look.

2. Training and professionalising the successor

Where there is a successor, they are rarely ready from the outset. The transfer of power is gradual: the successor takes on growing responsibilities while the predecessor moves into a mentoring role. Professionalising the management, separating ownership from leadership and bringing in outside executives where needed, is usually the lever that protects the most value.

3. Designing the protocol and the governing bodies

With the horizon set, the family protocol is formalised and the governing bodies are designed or reinforced. This is where the family decides how ownership will be separated from management, if at all, and how to balance the interests of the heirs who work in the company against those who do not.

4. Tax and wealth planning

Tax has to be anticipated, never improvised after a death. This is where the 95% reduction under the Impuesto sobre Sucesiones y Donaciones and the exemption under the Spanish wealth tax come into play, both of which we cover in the next section.

5. Execution and support

The actual handover takes place once everything above has matured. An orderly transition reassures employees, clients, suppliers and banks, all of whom need to know that the company has a future.

How is the succession of a family business taxed in Spain?

Tax is one of the factors that most shapes a generational handover, and also one of the most misunderstood. The Spanish system provides powerful incentives so that a family business can be passed on without the tax burden forcing a sale or draining its capital, but those reliefs come with strict requirements.

95% reduction under the Impuesto sobre Sucesiones y Donaciones (Spanish inheritance and gift tax). Article 20.2.c) of Ley 29/1987, the Spanish inheritance and gift tax act, provides that on mortis causa acquisitions of a sole trader business, a professional practice or shareholdings in entities covered by the wealth tax exemption, the spouse, descendants or adopted children may apply a 95% reduction to the value included in the taxable base, provided the acquisition is held for the ten years following the death (Ley 29/1987, art. 20.2.c, BOE). That is the national rule; many Spanish autonomous regions have improved the percentage or relaxed the holding period, so the final tax bill depends on the region where the deceased was resident.

95% reduction on lifetime gifts. The handover does not have to wait for a death. Article 20.6 of the same act allows the 95% reduction to be applied to a lifetime gift of the family business as well, subject to further conditions: the donor must be 65 or older (or permanently incapacitated), must step back from management duties and stop being paid for them, and the recipient must hold on to what they receive (Ley 29/1987, art. 20.6, BOE). Making the gift during the owner's lifetime allows the handover to be organised deliberately rather than left to the timing of a death.

Exemption under the Spanish wealth tax. The gateway to these reliefs is the exemption in article 4.Ocho of Ley 19/1991, the Spanish wealth tax act. For shareholdings to be exempt, and therefore able to benefit from the 95% reduction, three conditions must broadly be met: a minimum stake in the entity (held individually or by the family group), management duties carried out by the holder or by a member of the group, and pay for those duties amounting to more than half of that person's earned and business income (Ley 19/1991, art. 4.Ocho, BOE).

The practical conclusion is clear: these reliefs are not automatic. Reaching the handover while meeting the requirements of the wealth tax exemption means preparing the corporate structure and the position of each family member years in advance. That is why tax planning cannot be separated from succession planning.

The tax side of a handover is something you prepare, not something you suffer. If you want to go deeper into how the transfer is taxed, read our guide on the tax treatment of a company sale, holding companies and tax neutrality.

And if there is no successor? The option of selling to a third party

Not every family business has a natural successor, and that is fine. When there is nobody with the will or the ability to take over, or when the family would rather turn the wealth it has built into cash, selling to a third party is a perfectly legitimate way out, and often the one that best protects both the value of the company and its continuity.

Considering a sale does not mean giving up the legacy: it means making sure the company keeps trading, that employees keep their jobs and that the family capitalises on decades of effort. The most common routes are:

• Sale to a strategic or industrial buyer: a company in the sector looking to grow by absorbing capabilities.
• Sale to a private equity fund: bringing in capital and professional management.
• Management buy-out (MBO): the current management team buys the company, which secures continuity.

This decision calls for the same rigour as a family handover. It pays to know what the company is really worth before taking any decision, because the valuation shapes the whole negotiation. From there the process follows the classic stages of an M&A deal: preparation, buyer search, due diligence, negotiation and completion. If selling comes into the picture, it is worth understanding how the company sale process works in Spain.

What matters is that the decision, family succession or sale, is taken on the basis of information rather than by elimination or under time pressure. Many families find out too late that selling on good terms also took years of preparation.

A generational handover is a decision you prepare well in advance

A generational handover in a family business is not an act but a process. Whether the decision is to pass the company to the next generation or to sell it to a third party, the common factor is the same: anticipation. Families who plan years ahead protect the value of the business, avoid conflict and make use of the Spanish tax reliefs; those who improvise usually pay the price for not having done so.

A well-designed handover brings three pieces together: a family protocol that orders the relationship, a succession plan that professionalises the transition and a tax strategy that uses the 95% reduction and the wealth tax exemption while meeting their requirements. And where there is no successor, keeping the option of a sale open with the same seriousness.
