Family businesses make up more than 85% of Spain's business fabric. But the profile of that family business has changed fundamentally over the past two decades. Globalisation, the international mobility of business-owning families, the entry of private equity funds as minority shareholders, and the involvement of foreign strategic partners have transformed what was once a predominantly domestic picture into a genuinely cross-border reality.
The result is an advisory gap that very few firms address in an integrated way. A Spanish family business today needs to plan succession not only under the Civil Code and the regional rules of the Inheritance and Gift Tax (Impuesto sobre Sucesiones y Donaciones, ISD), but also by considering EU Succession Regulation 650/2012, the double tax treaties applicable to each heir or shareholder depending on their country of residence, and family protocol provisions that will be enforceable before courts or arbitrators in multiple jurisdictions.
This article covers the eight critical elements of family business succession with an international dimension, with specific references to current EU and Spanish legislation.
1. What makes a business succession “international”?
The international dimension can arise through multiple routes, not always obvious at the start of the planning process:
Heirs or shareholders resident abroad. A son or daughter who studied overseas, married a foreign national and settled there is the most common case. Their tax residence in another State determines how their inheritance is taxed there and can create double taxation if no double tax treaty (DTT) covers the inheritance, or if the applicable treaty does not specifically address estate and gift taxes.
Non-resident shareholders. The entry of a European or North American private equity fund, a foreign angel investor, or a French or German industrial partner converts any succession of the majority shareholder into an event with consequences for the corporate structure that extend well beyond Spanish law. The fund’s drag-along, tag-along and preferred liquidity rights can be triggered at the moment of succession if they have not been carefully managed in the shareholders’ agreement and family protocol.
Founder with dual nationality or residence abroad. The Spanish entrepreneur living and working in London, Geneva or Miami presents a particularly complex situation: their habitual residence may subject the entire succession to a different national law, with consequences for the distribution of the estate between spouse, children and other heirs.
Business assets in multiple countries. A company with subsidiaries in Portugal, Mexico or the United Arab Emirates adds the complexity of the succession of interests in foreign entities, each subject to the local law of that country.
2. EU Succession Regulation 650/2012 and the choice of applicable law
Regulation (EU) 650/2012 of the European Parliament and of the Council, of 4 July 2012, on jurisdiction, applicable law, recognition and enforcement of decisions and acceptance and enforcement of authentic instruments in matters of succession, is the governing instrument for cross-border successions within the EU since 17 August 2015.
The default rule: habitual residence at the date of death
Article 21 of the Regulation establishes that the law applicable to the succession as a whole is the law of the State where the deceased had their habitual residence at the date of death. This unity-of-succession principle is a significant improvement over the prior system — which split the succession between the law of the deceased’s domicile for movable assets and the lex situs for immovable assets — but introduces a new uncertainty for entrepreneurs with variable residence: if the founder of a Sevillian company spends his final years in Luxembourg for business reasons, the succession of his shares in the Spanish company may fall under Luxembourg law.
Professio juris: choosing the applicable law
Article 22 of the Regulation introduces one of the most valuable mechanisms in international succession planning: professio juris, or the choice of applicable law. A person may designate, in a will or in a declaration made in the form of a disposition of property upon death, that the law of the State whose nationality they possess at the time of making the choice or at the time of death shall govern their succession as a whole.
For the Spanish entrepreneur resident abroad, this choice is often the most important decision in their succession planning. Spanish law may be more favourable from several perspectives: the forced heirship rules of the Civil Code (legítima) reserve two-thirds of the estate for compulsory heirs (legitimarios), but in regions with their own civil law traditions — Catalonia, the Basque Country, Navarre, Aragon, Galicia and the Balearic Islands — succession agreements made during the owner’s lifetime (pactos sucesorios) provide considerably greater flexibility to designate a specific heir. A Catalan entrepreneur resident in Germany can choose that their succession be governed by Catalan law, avoiding the Pflichtteil rules of the German BGB, which operate differently from the Spanish legítima.
The Regulation does not apply to the United Kingdom or Denmark (opt-outs), which introduces additional complexity for business families with UK links post-Brexit. The succession of a Spanish-resident founder with heirs in the UK requires analysing both the Regulation — applicable from the Spanish side — and English private international law, which maintains the distinction between movables (law of the deceased’s domicile) and immovables (law of the situs).
The European Certificate of Succession
Article 62 of the Regulation creates the European Certificate of Succession: a document issued by the authority of the competent Member State (in Spain, the notary) that proves the status of heir, legatee, executor or administrator of the estate, and that has direct effect in all Member States. For the succession of shares in a family business with partners in other EU States, the European Certificate of Succession simplifies the transfer procedure before each country’s commercial registry.
3. Inheritance and Gift Tax with non-resident heirs
The tax treatment of inheriting a Spanish family business varies dramatically depending on whether the heirs are resident or non-resident in Spain, and in which autonomous community the inheritance is taxed.
The Spanish ISD regional map
Spain’s ISD presents a fiscal fragmentation with no equivalent in any other national tax. The differences between autonomous communities are extreme:
- Madrid: 99% rebate on tax due for acquisitions by spouse, descendants and ascendants. In practice, the inheritance of a family business taxed in Madrid carries almost zero cost for the heir.
- Andalusia: since 2019, a 99% rebate for the same family groups, matching Madrid.
- Murcia: 99% rebate for Groups I and II.
- Valencia: 50% rebate for Group I (descendants under 21) and variable reductions for others, with effective rates materially higher than Madrid or Andalusia.
- Catalonia: no general regional rebate; effective rates range from 7% to 32% depending on the heir’s own wealth.
- Basque Country and Navarre: own foral regimes, with entirely independent rules.
This regional competition creates incentives to plan the founder’s tax residence: moving to Madrid or Andalusia before death can substantially reduce the tax burden on heirs. However, the AEAT and the courts have begun scrutinising changes of residence made in the last years of life without genuine motivation.
The Welte ruling and Law 26/2014
The Court of Justice of the European Union ruling in Welte (Case C-181/12, 17 October 2013) was a watershed moment. The CJEU declared incompatible with the free movement of capital (Article 63 TFEU) the Spanish rules that denied non-residents in Spain the right to apply the most favourable regional rules for ISD, forcing them to pay at the national scale — with rates up to 34% — without access to the regional rebates.
Law 26/2014, of 27 November, amended the ISD Law accordingly. Non-residents in Spain who reside in the EU or EEA have been entitled since then to apply the regional rules of the relevant autonomous community. And, pursuant to subsequent case law — including the CJEU ruling in Feilen (Case C-123/15) — and TEAC resolutions, this right has been extended to residents outside the EU/EEA, though with important procedural nuances.
In practice: an heir resident in New York or São Paulo can claim the 99% rebate available in Madrid or Andalusia, even though the inheritance is filed with the central AEAT. This right is not automatic — it requires active management with the Tax Authority, often including administrative appeals or claims before the Tribunal Económico-Administrativo Central (TEAC).
The 95% business relief
The 95% reduction on the taxable value of the inherited family business — provided in Article 20.6 of Law 29/1987 (ISD Act), with additional improvements in several autonomous communities — is the fiscal cornerstone of any Spanish family business succession. Its essential conditions are:
- The deceased must have exercised effective management functions in the business, remunerated at a level representing more than 50% of their net income from employment and economic activities in the year of death.
- The business must not have as its primary activity the management of a portfolio of movable or immovable assets (a sociedad de cartera within the meaning of Article 4.Eight of the Wealth Tax Act).
- The acquirers must retain the inherited assets for at least ten years, except in the event of death.
For the entrepreneur resident abroad, meeting the first requirement can be problematic: if management functions are exercised remotely or through a delegated managing director, the AEAT may challenge whether the founder truly “exercises management functions” for the purposes of the provision. Anticipatory planning — properly documenting the effective exercise of management functions — is essential.
4. The family protocol with an international dimension
The family protocol is the central governance document of any family business. When the business has international shareholders or heirs, its drafting acquires a qualitative complexity that goes well beyond producing versions in multiple languages.
Governing law of the protocol and parasocial agreements
The family protocol, as a contract between family members and the company, is subject to the law chosen by the parties under the Rome I Regulation (Regulation EC 593/2008 on the law applicable to contractual obligations). In the context of a Spanish family business with foreign shareholders, the standard and recommended choice is Spanish law, which is directly linked to the company’s registered office and commercial registry.
However, choosing Spanish law does not eliminate the possibility that a foreign shareholder may invoke ordre public rules of their country of residence when seeking to enforce the protocol there. For this reason, protocol provisions must be drafted with a robustness that makes them enforceable before courts or arbitrators in different jurisdictions.
Dispute resolution mechanisms
The choice of dispute resolution mechanism is a strategic decision of the first order when foreign shareholders are involved. Ordinary Spanish courts — with the juzgados de lo mercantil as the natural venue for corporate disputes — have the disadvantage that their judgments, while recognisable in the EU under the Brussels I bis Regulation (Regulation 1215/2012), are more complex to enforce outside Europe.
International arbitration — seated in Madrid (Corte Española de Arbitraje, CEA; Corte Civil y Mercantil de Arbitraje, CIMA) or under the rules of the International Chamber of Commerce (ICC) — offers clear advantages: an arbitral award is enforceable in over 160 countries under the New York Convention of 1958, the proceedings can be conducted in multiple languages, and the arbitrator can be selected for expertise in Spanish and international corporate law. For family protocols with shareholders in the UK, Latin America or Asia, an ICC arbitration clause with Madrid as the seat and proceedings in Spanish and English is the professional standard.
Tag-along and drag-along rights with international shareholders
Tag-along rights (the minority shareholder may sell on the same terms as the majority) and drag-along rights (the majority shareholder may compel the minority to sell to the same buyer at the same price) are standard in any company with financial investors.
Their interaction with business succession is critical: if the founder dies and the heirs do not fulfil the management functions the fund requires, or if the succession creates a deadlock in the management body, the fund’s drag-along provisions may be triggered and force a full sale of the business at the worst possible moment.
Pre-emptive planning must include:
- Step-in clauses for the designated successor, establishing their control position before the founder’s death through a progressive gift of shares.
- Lock-up covenants that temporarily restrict the exercise of drag-along rights in the event of the reference shareholder’s death, giving the successor time to consolidate their role.
- Third-party valuation mechanisms for tag-along events, using pre-agreed methodologies (EBITDA multiple, DCF with predetermined parameters) that avoid price disputes at the moment of succession.
Language and documentation
A practical point frequently overlooked: in a family business with British, German or Latin American shareholders, the language of corporate documents can create real problems. Board minutes, parasocial agreements and the family protocol must be available in the relevant languages, with the Spanish version as the official reference for commercial registry purposes and notarial execution.
5. Corporate governance for mixed family businesses
The presence of international shareholders — whether non-resident family members or external financial investors — creates governance demands that a purely domestic family business rarely needs to meet.
Board composition
The Board of Directors of a family business with international shareholders should reflect that diversity. The inclusion of independent directors — persons without family or financial ties to the main shareholders, selected for their sector or international expertise — is a standard requirement of private equity funds and foreign industrial partners with significant stakes.
The Spanish Companies Act (Real Decreto Legislativo 1/2010, as amended in 2014 and 2021) regulates directors’ duties with particular rigour: the duty of loyalty, the duty of diligence and the prohibition of conflicts of interest. In an international context, independent directors also act as guarantors of neutrality in the succession process, providing reassurance to foreign minority shareholders who might otherwise suspect that succession decisions have been taken exclusively in the interests of the founder’s heirs.
Family Council and Board of Directors: separating the spheres
In family businesses with non-family shareholders — whether funds, industrial partners or angel investors — the distinction between the Family Council (an internal family deliberative body, without corporate legal status) and the Board of Directors (the company’s governance body, with legal responsibilities) is more than a good governance practice: it is an investor requirement.
A PE fund or industrial partner wants to interact with the Board of Directors, where their representatives have voice and vote. They do not want to be drawn into internal family decisions. This separation, formalised in the family protocol, protects both the family (which retains its internal deliberation space) and the external investor (who operates within the standard corporate legal framework).
Reporting standards for international investors
PE funds and foreign industrial shareholders typically require periodic financial information under international standards — IFRS or, in the case of American funds, US GAAP — and in English. This can create tension with the obligation to maintain accounts under Spain’s Plan General Contable (PGC), which is the basis for tax reporting to the AEAT.
The standard solution is to maintain PGC accounts (a legal obligation) and additionally prepare a management report under IFRS or US GAAP for international investors. This dual reporting layer has a cost, but it is the price of access to international capital.
6. Tax structuring for succession with international shareholders
Tax planning for the succession of a family business with international shareholders brings together Spanish tax law, double tax treaties and the domestic tax rules of the countries where each shareholder or heir is resident.
The holding company and the ETVE regime
The Entidad de Tenencia de Valores Extranjeros (ETVE) is a Spanish tax regime — governed by Article 107 of the Corporate Income Tax Act (LIS) — designed specifically for the holding of interests in non-resident entities. Its main advantages are:
- Dividends and capital gains derived from interests in non-resident entities are exempt from Spanish CIT in the ETVE (Article 21 LIS), provided the minimum participation (5%) and holding period (one year) requirements are met.
- Dividends distributed by the ETVE to its non-resident shareholders are exempt from withholding tax in Spain, provided the shareholders are resident in a country not considered a tax haven (Article 107.2 LIS).
For the Spanish family business with foreign subsidiaries and partially non-resident shareholders, the ETVE is the most efficient holding vehicle. In the succession context, concentrating all interests in the Spanish ETVE simplifies the process: the inheritance falls on the ETVE’s Spanish shares, subject to Spanish ISD rules, rather than affecting separately the interests in each foreign subsidiary according to the law of each country.
The participation exemption (Article 21 LIS) and dividend planning
Article 21 of the LIS, in its current version following Law 40/2015 and subsequent amendments, provides a 95% exemption (reduced from 100% after the 2021 reform) on dividends and capital gains from foreign sources. This exemption is the backbone of tax planning for Spanish business groups with international operations.
In the succession context, the participation exemption serves two purposes: (1) it allows repatriation of profits from foreign subsidiaries to the Spanish holding at reduced tax cost before the succession, accumulating liquidity to cover the ISD; and (2) it facilitates the business valuation for succession purposes, by documenting the group’s dividend-generating capacity consistently.
Withholding tax on dividends to non-residents: double tax treaties
When the family business distributes dividends to non-resident shareholders — whether heirs living abroad or funds seated in Luxembourg or Ireland — withholding tax is the first fiscal consideration. Spain has double tax treaties with more than 90 countries, which typically reduce the withholding rate on dividends to 5-15% (against the general 19% rate established in the Non-Resident Income Tax Act for non-residents).
The most frequent situations in the international family business:
- Heir resident in the UK: Spain-UK DTT limits withholding to 10-15% depending on the stake.
- Heir resident in the United States: Spain-US DTT (1990, with 2013 Protocol) limits withholding to 5% if the stake exceeds 25%, and 10% otherwise.
- Fund seated in Luxembourg: Spain-Luxembourg DTT, 5% withholding if the stake exceeds 10%.
- Heir resident in Mexico: Spain-Mexico DTT (1994), 10% withholding.
The succession event is an opportunity to review and optimise the holding structure based on the treaties applicable to the new heir-shareholders, whose residence may differ from that of the deceased founder.
Avoiding international double taxation on inheritances
Many countries tax the inheritances of their residents on assets located abroad, which can create double taxation when Spain also taxes the same inheritance. Spain has bilateral conventions specifically covering ISD with France, Greece and Sweden — leaving most of the most common situations uncovered by treaty (heirs in the UK, Germany or the United States).
In the absence of a treaty, the ISD Act provides a unilateral foreign tax credit (Article 23 of Law 29/1987): the heir may deduct from the Spanish tax the amount paid abroad on the same assets, up to the limit of the Spanish tax attributable to those assets. This credit does not eliminate double taxation entirely but mitigates it.
A prior structural solution — creating the Spanish holding as the vehicle for all assets — can substantially reduce this problem, by converting the inheritance of assets spread across multiple countries into the inheritance of interests in a single Spanish entity, taxed primarily in Spain.
7. Three common scenarios
Scenario A: Sevillian founder, three children — one in London, one in Houston, one in Seville
The founder is 72, resident in Seville, and sole owner of a logistics services company with €35 million in turnover. He has three children: María, resident in Seville and the company’s Operations Director; Carlos, resident in Houston, Texas, for the past twelve years, with dual Spanish-American nationality; and Paloma, resident in London since 2015, married to a British citizen.
Without planning, the inheritance would attract ISD in Andalusia (99% rebate, virtually zero cost) for María, but Texas estate tax considerations for Carlos and potential UK Inheritance Tax exposure for Paloma (depending on their domicile status under English law) complicate the picture. The solution: a lifetime gift of the majority of shares to María — who assumes operational control — using the Andalusia 99% rebate, with a professional independent valuation of the company to fix the tax base. For Carlos and Paloma, the holding structure is redesigned to pay dividends subject to reduced withholding under the Spain-US and Spain-UK DTTs.
Scenario B: Catalan company with a German industrial partner seeking an exit
A Catalan industrial technology company, with a German Mittelstand industrial partner holding 30% for eight years, and a 65-year-old founder with three children. The German partner holds tag-along rights under the shareholders’ agreement and wants liquidity within three years. If the founder’s succession occurs during the uncertainty period, it may trigger the German partner’s drag-along.
The solution: a renegotiated family protocol incorporating a step-in clause for the eldest son (brought into management with delegated powers two years prior), a three-year lock-up on the exercise of drag-along rights in the event of the founder’s death, and a parallel process to find a buyer for the German partner’s stake through a partial secondary buyout before the founder retires.
Scenario C: The next generation returning from abroad
The son of a Valencian entrepreneur, having spent ten years in Singapore and returning to Valencia to take over the family pharmaceutical distribution business (€60 million in turnover), illustrates a frequent complication: during ten years in Singapore, the son built personal wealth and established non-Spanish tax residence. His return to Spain may trigger Spanish tax obligations from day one, including disclosure of foreign assets (Form 720, restructured after the 2022 CJEU ruling), and an analysis of whether his prior situation precludes him from the Ley Beckham regime for the early years of his return.
Planning in this case requires coordinating tax advice in Singapore (for the orderly closure of his tax residence there) with advice in Spain (for optimising the return, analysing the Beckham regime and designing the father’s succession structure).
8. The three-year succession timeline
International family business succession is not a six-month project. BMC’s experience with this type of engagement indicates that three years is the realistic horizon, structured in four phases:
Year 1 — Diagnosis and governance
The first year is devoted to a complete diagnosis: inventory of assets in all countries, analysis of the shareholding structure and existing agreements, assessment of the tax position of each family member in their jurisdiction of residence, and design of the future governance architecture. In this phase, the successor or successors are identified, the post-succession Board model is defined, and the first decisions on the holding structure are taken.
Year 1-2 — Family protocol and parasocial agreements
The negotiation and formalisation of the family protocol is the core of the process. With international shareholders, this phase necessarily includes negotiating tag-along, drag-along and liquidity clauses with non-family shareholders. The protocol must be executed before a Spanish notary, translated into all relevant languages, and apostilled where required for its effectiveness in the countries of residence of foreign shareholders.
Year 2-3 — Tax structuring
The creation or reorganisation of the holding company, the implementation of the ETVE regime where appropriate, the review of applicable DTTs for each shareholder, and an updated independent valuation of the business to fix the reference price for progressive lifetime gifts. This phase also includes arranging life insurance policies sized to provide the liquidity needed for ISD payment by heirs without sufficient personal resources.
Year 3 — Execution and gradual transfer
The progressive transfer of control — through share gifts, delegation of powers and changes to the management body — is completed in the third year, with the successor established in their role before the founder fully retires.
9. BMC’s integrated approach
The succession of a family business with an international dimension cannot be handled in a fragmented way. Separating the lawyer who drafts the protocol from the tax advisor who handles the ISD from the consultant who designs the holding structure is, in this type of engagement, the principal risk factor.
BMC offers an integrated approach across three disciplines:
Legal: Drafting and negotiating a family protocol with clauses enforceable in multiple jurisdictions, parasocial agreements adapted to each shareholder’s position, analysis of the professio juris election under Regulation (EU) 650/2012, and — where insolvency proceedings affecting a shareholder or the company require it — specialist insolvency law advice provided by Raúl Herrera García, letrado specialising in insolvency law, registered with the ICAM (No. 79,836).
Tax: ISD optimisation for resident and non-resident heirs — applying the Welte jurisprudence and the most favourable regional regime —, analysis of applicable DTTs for each shareholder, ETVE holding structuring, planning of lifetime gifts and management of international double taxation.
Corporate: Governance redesign for the post-succession phase: composition of the new Board of Directors, incorporation of independent directors that satisfy the expectations of international shareholders, design of the Family Council framework, and reporting infrastructure for foreign investors.
If your family business has shareholders or heirs based abroad, or if you are considering the entry of an international partner before beginning the succession process, the BMC team can help you design a roadmap that accounts for all the relevant variables: legal, tax and governance.
