In the business landscape of the Autonomous Region of Madeira, preserving a legacy requires a legal architecture that anticipates risks. Simply holding assets in a personal capacity or within a single operating company is, today, a structural vulnerability.

Por isso, no artigo de hoje analisamos, com rigor jurídico e foco prático, de que forma a constituição de uma holding - tipicamente sob a forma de SGPS - pode ser a ferramenta mais eficaz de segregação patrimonial, eficiência fiscal e planeamento sucessório para o empresário madeirense.

Therefore, in today’s article, we analyze - with legal rigor and a practical focus - how the establishment of a holding company (typically incorporated as an SGPS) can be the most effective tool for asset segregation, tax efficiency and succession planning for Madeira entrepreneurs.

01 What is a holding company and which legal form should be adopted?

In essence, a holding company is an entity whose primary activity consists of holding and managing shareholdings in other companies. In Portugal, the preferred legal vehicle is the Shareholding Management Company (known by the Portuguese acronym SGPS), governed by Decree-Law No. 495/88 of December 30, as subsequently amended.

The exclusive corporate purpose of an SGPS is the management of equity interests as an indirect means of engaging in economic activities. This exclusivity of purpose is both an advantage and a limitation. Its advantage lies in the provision of a clear legal and tax framework. Conversely, its disadvantage is that, as a general rule, it cannot directly provide services to its subsidiaries or carry out operational activities, except for legally defined exceptions (e.g., the provision of technical or financial management services to subsidiaries under Article 4 of the aforementioned Decree-Law).

Alternatively, a holding structure may be established through a joint-stock company (S.A.) or a limited liability company (Lda.) with a general corporate purpose that includes the holding of interests. This solution offers greater operational flexibility but forfeits some of the specific benefits of the SGPS regime. The choice of legal form must be made on a case-by-case basis through specialized legal counsel.

02 Asset Autonomy: What the Law says (and what it does not)

The primary financial argument for a holding structure is the separation between assets exposed to operational risk and long-term strategic assets. The entrepreneur’s strategic assets (e.g., real estate, shareholdings, intellectual property) are held in an entity distinct from the operational companies exposed to daily commercial risk.

The legal basis for this separation is the principle of separate legal personality, enshrined in Article 5 of the Portuguese Commercial Companies Code (CSC). Each company within the group is an autonomous subject of rights and obligations, with its own distinct assets. Consequently, the debts of the operational subsidiary (or affiliate) are not, in principle, enforceable against the holding company.

Dizemos "em princípio", pois é entendimento pacífico, tanto na jurisprudência quanto na doutrina portuguesas, que o princípio da atribuição da personalidade jurídica às sociedades e da separação de patrimónios, não constitui um valor absoluto. Como, de resto, o Supremo Tribunal de Justiça já se pronunciou em diferentes contextos:

We say "in principle" because it is a settled understanding in both Portuguese case law and legal doctrine that the principle of legal personality and the segregation of assets is not an absolute value. Indeed, the Supreme Court of Justice (STJ) has ruled on this in various contexts:

«The principle of legal personality and the segregation of assets, being a legal fiction, cannot be viewed in itself as an absolute value; nor can it serve as a cloak or veil to protect illicit or abusive practices - contrary to the legal order - which are censurable and detrimental to third parties. Thus, whenever the collective personality is used, or comes to be used, as an instrument for the abusive pursuit of interests foreign to its corporate purpose, or contrary to general rules or principles such as good faith and abuse of right, the piercing of the corporate veil must occur, after weighing the true interests at stake, this allows for the holding of those who stand behind and control the company’s (fictional) autonomy accountable.»

This excerpt is taken from an STJ Ruling of 2019, in which the Court reiterated and cited the position it had already adopted in 2017. The Ruling may be consulted here (in portuguese language).

03 The real risk: piercing the corporate veil

The protection afforded by asset autonomy, as we have seen, is not absolute. Portuguese - and European - jurisprudence recognizes the doctrine and mechanisms of piercing the corporate veil whenever the corporate structure is used in an abusive manner (see, in this regard, the Supreme Court of Justice Ruling of 09-05-2019).

The primary risk factors considered by the courts include:

Commingling of Assets: The indistinct use of the assets of the holding company and its subsidiaries, the lack of separate accounting records, or the payment of personal expenses through the company;

Deliberate Undercapitalization of Operational Units: The establishment of subsidiaries that are intentionally incapable of meeting their liabilities, while artificially transferring assets to the holding company;

Lack of Economic Substance: Purely nominal structures, lacking effective management or real investment decision-making, created solely to generate an appearance of separation;

Fraud on Creditors: The transfer of assets to the holding company close to the onset of litigation or imminent insolvency, with the intent to shield them from execution.

In a small-scale region like Madeira, where commercial relationships are close-knit and the courts are familiar with local economic agents, this caveat is particularly relevant. The structure must be substantively real, not merely formally correct.

04 Tax efficiency: the participation exemption regime

The most significant tax advantage of a holding company is access to the participation exemption regime, as provided for in Article 51 of the Corporate Income Tax Code (CIRC) for dividends, and Article 51-C for capital gains on the disposal of shareholdings.

Dividends: Eligibility Requirements

Profits and reserves distributed by subsidiaries to the holding company are exempt from Corporate Income Tax (IRC), provided that the following cumulative requirements are met:

The holding company holds, directly or indirectly, at least 10% of the share capital or voting rights of the subsidiary. (Note: the threshold was increased from 5% to 10% in 2014; citing the previous percentage is a common error);
The participation is held uninterruptedly for at least one year (this period may be completed after the distribution).
The distributing subsidiary is not subject to a tax transparency regime.
The distributing subsidiary is subject to income tax at a rate not lower than 60% of the nominal IRC rate applicable in Portugal (an anti-hybrid and anti-tax haven rule).

Practical Impact:

Instead of the liquidity generated by operational units being taxed under Personal Income Tax (IRS) at the shareholders' level (at a 28% flat rate or aggregated rates), it remains within the group for reinvestment without additional taxation. This tax neutrality is the driving force behind the capitalization of Madeira business groups.

Capital Gains: The Article 51-C Exemption

The disposal of shareholdings by the holding company may also benefit from an IRC exemption on realized capital gains, provided the same minimum holding requirements are met (10% for one year) and the subsidiary is not resident in a tax haven.

Transfer Pricing: An Obligation Not to Be Ignored

The entire group structure is subject to transfer pricing rules under Article 63 of the CIRC. Transactions between the holding company and its subsidiaries (provision of management services, intra-group financing, intellectual property licensing) must be conducted at arm's length - meaning, on the same terms that would be practiced between independent entities. Non-compliance can lead to significant tax adjustments and fines.

Taxation That Does Not Vanish: IRS on Final Distribution

A holding company defers taxation; it does not eliminate it. When the profits accumulated in the holding company are ultimately distributed to individual shareholders, they will be taxed under IRS (28% flat rate, unless the option for aggregation is exercised). Planning must account for this reality and optimize both the timing and the method of distribution.

05 The 'Madeira factor': The MIBC and its role in structuring

Any analysis of corporate structuring in Madeira that fails to mention the Madeira International Business Centre (MIBC) - also known as the Madeira Free Trade Zone - is incomplete. The MIBC is the most distinctive element of the regional landscape and, for many business groups with international operations, the primary reason for choosing Madeira as a location.

Current Legal Framework: Regime IV, through 2033

The current MIBC framework — designated as Regime IV — was approved by the European Commission as State aid compatible with the internal market, under the provisions of the Treaty on the Functioning of the European Union (TFEU) regarding outermost regions. It is regulated by Article 36.º-A of the Tax Benefits Statute (EBF).

In November 2025, within the scope of the 2026 State Budget, the Portuguese Parliament approved the extension of the regime's effects for an additional five years. The current framework is as follows:

The licensing of new entities is open until December 31, 2026 (this deadline was not altered by the approved extension).
Entities licensed between January 1 of 2015 and December 31 of 2026, benefit from a 5% IRC rate on eligible profits until December 31 of 2033.
Shareholders of these entities also enjoy an exemption from IRS or IRC on distributed profits until December 31 of 2033, except for those originating from transactions with entities in tax havens.

Official Sources for Verification

The regime can be directly verified through three primary sources: the official MIBC website — www.ibc-madeira.com — managed by SDM (Sociedade de Desenvolvimento da Madeira), the concessionaire entity; and Article 36-A of the Tax Benefits Statute (EBF), available at dre.pt (the Portuguese Electronic Official Gazette).

The 5% Rate: Scope and Limits

The reduced 5% IRC rate applies to profits generated from eligible activities carried out with entities non-resident in Portugal. It is important to emphasize that when an MIBC entity conducts transactions with Portuguese companies not licensed within the regime, that income is taxed at the general IRC rate. In the Autonomous Region of Madeira, this rate is 13.3% — reflecting the regional tax reduction policy, as opposed to the 19% rate in force in Mainland Portugal.

This regime is particularly relevant for holdings with international activity: managing participations in foreign subsidiaries, providing intra-group services at a European or global level, or acting as vehicles for intellectual property management with exploitation outside of Portugal.

Access Conditions: Substance is Non-Negotiable

The MIBC is not - and has never been - a "letterbox" regime. In 2018, the European Commission launched an investigation into the previous framework (Regime III), concluded in 2020, precisely due to non-compliance with substance and job creation requirements. This recent history must be taken into account by any entrepreneur considering the MIBC.

Eligibility requirements for Regime IV are mandatory and cumulative:

Prior Licensing by the SDM (Sociedade de Desenvolvimento da Madeira);
Job Creation: Creation of effective jobs in the Region (between 1 and 6 positions, depending on the taxable income threshold, according to Article 36.º-A of the EBF);
Minimum Investment: A minimum investment of €75,000 (when applicable); and
Genuine Economic Substance: Effective management, physical premises, and local decision-making in Madeira. Purely formal structures, lacking operational reality, are not only ineligible but may lead to retroactive tax liability and, in extreme cases, criminal liability.

Synergy with the Participation Exemption Regime

The coordination between the 5% MIBC corporate tax rate and the participation exemption regime (Article 51.º of the CIRC), when properly structured and documented, allows for the creation of a business group with a highly competitive aggregate tax burden within Europe - while remaining in full compliance with national and EU law. This synergy is, in practice, the most powerful tax argument for Madeira as a jurisdiction for international holding companies.

Note-se que, como referido, quando abordámos a matéria dos preços de transferência, todas as operações intragrupo entre a holding CINM e as restantes entidades do grupo devem ser realizadas em condições de plena concorrência e devidamente documentadas - independentemente dos benefícios fiscais aplicáveis.

It should be noted that, as previously mentioned regarding transfer pricing, all intra-group transactions between the MIBC holding and the other group entities must be conducted at arm's length and properly documented, regardless of the applicable tax benefits.

06 Family succession: legal instruments

The Madeiran business landscape is primarily composed of family-owned SMEs. Succession is frequently the event that defines the survival or fragmentation of a business built over generations.

A holding company offers a structural solution: instead of fragmenting operational assets or real estate among heirs - which can lead to management paralysis due to a lack of consensus - the family holds interests in the holding company. This preserves the unity of the companies that generate employment and wealth in the Region.

Shareholders' Agreements: Scope and Limitations

O acordo de sócios - tecnicamente designado por acordo parassocial, previsto no artigo 17.º do CSC - é um instrumento central na estruturação de qualquer holding familiar ou de grupo. É útil para disciplinar o exercício do direito de voto, cláusulas de preferência, de acompanhamento (tag-along) ou de arrastamento (drag-along), e regras de transmissibilidade das participações. The shareholders' agreement - technically referred to as a voting agreement or acordo parassocial under Article 17.º of the CSC - is a central instrument in structuring any family or group holding. It is essential for governing the exercise of voting rights, right of first refusal clauses, tag-along or drag-along rights, and rules regarding the transferability of shares.

In fact, we have previously highlighted its relevance in the context of foreign investment and venture capital in Madeira in another blog post, which we recommend: The new venture capital landscape in Madeira: preparing your company for investment while maintaining legal control.

Statutory Corporate Governance Instruments

Statutory Right of First Refusal: Grants existing shareholders the right to acquire shares before any transfer to third parties;
Consent Clauses: Subordinate the transfer of shares to the prior approval of the company or the remaining shareholders;
Qualified Quorum Rules: Require a supermajority for strategic decisions, preventing simple majorities from imposing decisions detrimental to family minorities;
Family Council or Family Protocol: A governance instrument (not necessarily strictly legal in nature) that defines succession rules, heir training, and conflict resolution before such issues reach the courts.

Stamp Duty on Gratuitous Transfers

The gratuitous transfer of shareholdings, whether inter vivos (donations/gifts) or mortis causa (inheritance), is subject to Stamp Duty at a rate of 10% on the value of the shares, calculated under the Stamp Duty Code (CIS).

However, transfers between spouses or civil partners, descendants, and ascendants are exempt from this tax. Consequently, succession planning must consider not only the valuation of the holdings but also the timing and method of the transfers, ensuring the continuity of family control with the lowest possible tax burden.

07 Economic substance and the General Anti-Abuse Rule (GAAR)

The Portuguese Tax Authority (AT) possesses a fundamental instrument to combat aggressive tax planning: the General Anti-Abuse Rule (GAAR), as provided for in Article 38.º, n.º2 of the General Tax Law (LGT). This provision allows the AT to disregard legal acts or transactions carried out with the primary objective of obtaining tax advantages that run contrary to the spirit of the law, even if they are formally lawful.

For a holding structure to be respected by the AT and the courts, it must demonstrate genuine economic substance, which specifically implies:

Effective Management and Seat in Madeira: Not a mere postal address, as previously mentioned;
Actual Decision-Making: Investment and management decisions regarding the shareholdings must be effectively made by the holding company;
Adequate Resources: Human and material resources commensurate with the declared activity;
Organized Accounting: Proper record-keeping and documentation of management decisions (minutes, reports, correspondence);
Arm’s Length Remuneration: Market-rate compensation for intra-group services, supported by transfer pricing studies where applicable.

The establishment of a holding company for exclusively tax-related reasons, without corresponding to a substantive reality, creates a high-risk scenario, particularly in the absence of rigorous and detailed planning.

Final considerations

The establishment of a holding structure is an unequivocal sign of corporate maturity. When properly designed, it offers the Madeira entrepreneur a set of advantages that are difficult to replicate through other means: an effective separation between operational risk and strategic assets, tax efficiency in the reinvestment of profits, and a robust legal framework for business continuity across generations.

It is not, however, a universal solution, nor is it without risk. The transition to a holding model must be preceded by an in-depth legal and tax analysis, focused on the specific reality of your company and the unique context of the Autonomous Region of Madeira, including the opportunities and obligations arising from the MIBC regime, as discussed throughout this article.
