Investors setting up a company in Portugal usually end up choosing between two corporate forms: the private limited company (sociedade por quotas, Lda.) and the public limited company (sociedade anónima, SA). The decision is often made quickly, based on the available capital, the number of shareholders or the investor’s home-country practice. That is understandable, but it has practical consequences. The corporate form determines who controls management, how much it costs to maintain the structure, how easily a new investor may enter and how far a minority shareholder may block decisions. For a broader view of the incorporation process, see our guide to setting up a company and main corporate obligations in Spain and Portugal.
This article explains the main differences between an Lda. and an SA, based on the Portuguese Companies Code and their practical effects for domestic and foreign investors.
An Lda. and an SA share the essentials. Both have separate legal personality, both are liable for their debts with their own assets and, in both cases, shareholders’ risk is limited to the capital they have invested.
The difference lies in the model that the law has in mind. The Lda. was designed for a small group of shareholders who follow the life of the company closely and want to control who enters the share capital. The SA was designed for projects with more capital, more shareholders and more easily transferable holdings, with a clearer separation between investors and managers. This choice should be coordinated with the corporate governance structure to be implemented from the outset.
An Lda. may be incorporated by two shareholders or by a single shareholder, in which case it is called a single-member quota company. The sole shareholder may be an individual or a company.
An SA generally requires five shareholders. The law allows an SA to have a single shareholder where that shareholder is a company, which allows a group to hold a wholly owned subsidiary. An individual, however, cannot incorporate an SA alone. Two entrepreneurs wishing to split a company 60/40 may do so directly in an Lda.; in an SA, they would need to find three additional shareholders or interpose a company.
The difference is even clearer when it comes to capital. In an Lda., share capital is freely set by the shareholders, with a minimum of 1 euro per quota. Cash contributions may be paid up until the end of the first financial year or, if the articles so provide, deferred to a later date. However, there is a rule that surprises many investors: each shareholder is liable to the company for their own contribution and also, jointly and severally, for the contributions of the other shareholders. If one shareholder fails to pay the amount subscribed, the others may be called upon to cover it.
A capital of 2 euros is legal, but it rarely convinces a bank, landlord or supplier. In practice, share capital commonly ranges between 1,000 and 50,000 euros, adjusted to the scale of the business.
In an SA, the minimum share capital is 50,000 euros. The law allows up to 70% of cash contributions to be deferred for up to five years, so 15,000 euros is sufficient on incorporation. The capital is divided into shares, with or without nominal value, and all shares are registered. Bearer shares have not existed since 2017.
In an Lda., management is entrusted to one or more managers, who must be natural persons and may be shareholders or third parties. Unless otherwise provided, the appointment has no fixed term: the manager remains in office until resignation or removal. Shareholders may remove a manager at any time, but without just cause the company may have to indemnify the manager.
The most characteristic feature of an Lda. is the weight of shareholders in management. Managers must comply with shareholder resolutions, which means that the general meeting may give instructions to management on specific matters, such as entering into a relevant contract or hiring a director. For a foreign group’s subsidiary, this rule is often an advantage: the parent company retains direct control over the local operation.
In an SA, the balance is different. Management may be entrusted to a sole director, if share capital does not exceed 200,000 euros, or to a board of directors, with terms of up to four years, renewable. Shareholders only decide on management matters when requested to do so by the board, which therefore acts with greater autonomy.
The board may delegate day-to-day management to a managing director or to an executive committee. A practical point: the board of directors must meet at least once a month, unless the articles provide otherwise. In a small SA, it is advisable to include that exception from incorporation.
An SA may choose between three governance models under article 278 of the Portuguese Companies Code:
The vast majority of small and medium-sized SAs adopt the classic model.
The statutory auditor (revisor oficial de contas, ROC) is an independent professional, registered with the relevant professional body, who audits the company’s accounts and issues the legal certification of accounts. The sole supervisor and supervisory board are company bodies which, in addition to monitoring accounts, supervise the legality of management.
In an SA, supervision is mandatory from day one. In the classic model, the company chooses between a sole supervisor, who must be a statutory auditor or statutory audit firm and have a substitute, and a supervisory board with at least three members, one of whom must be a statutory auditor. The term of office is up to four years.
Listed SAs, and those that for two consecutive years exceed two of the legal thresholds relating to balance sheet, net sales or employees, must have a supervisory board and, separately, a statutory auditor, unless they are wholly controlled by a company that already adopts that model.
In an Lda., supervision is generally optional. The articles may provide for a supervisory board, but the company is only required to appoint a statutory auditor if, for two consecutive years, it exceeds two of the applicable legal thresholds.
This is one of the differences with the greatest impact on annual cost. A small SA pays the fees of the sole supervisor from the first financial year, even before generating turnover. An Lda. with the same activity may spend several years without that cost. For a start-up business, the difference matters.
In an Lda., one vote is counted for each cent of the nominal value of the quota. The general meeting operates with any number of shareholders present and generally resolves by a majority of votes cast. Structural decisions, such as amending the articles, mergers, demergers, transformations or dissolution, require 3/4 of the votes corresponding to the share capital.
In an SA, the general meeting has a board with its own chair and quorum rules. To amend the articles on first call, shareholders representing 1/3 of the share capital must be present and the resolution must obtain 2/3 of the votes cast. On second call, there is no minimum quorum and 2/3 of the votes cast are sufficient, or a simple majority if half of the share capital is represented.
An example helps explain the difference. Consider a company with a 70% shareholder and a 30% shareholder, where the majority shareholder wishes to amend the articles. In an Lda., the minority shareholder blocks the amendment because 70% does not reach the required 75%. In an SA, with both shareholders present, 70% of the votes cast exceeds 2/3 and the amendment passes. In both forms, the articles and a shareholders’ agreement may reinforce these majorities. This is where minority protection, reserved matters, veto rights and other business law mechanisms are negotiated.
Information rights follow the same logic. In an Lda., any shareholder, regardless of their stake, may request information on management and inspect the company’s accounts and books. In an SA, access depends on the shareholding: shareholders with 1% have the right to minimum information, such as accounts and minutes, while shareholders with 10% may request written information on management. All shareholders may request clarifications at the general meeting.
The rules on profits are the same. Shareholders are entitled to receive at least half of the distributable profit, unless otherwise provided in the articles or by resolution approved by 3/4, and 5% of profit is allocated to the legal reserve until it reaches 20% of share capital.
The Lda. also has its own financing instrument: supplementary contributions. If the articles so provide, shareholders may be called upon to provide funds to the company without increasing share capital, and those amounts may later be repaid. The SA does not have this mechanism and relies on ancillary contributions or shareholder loans.
In an Lda., the transfer of quotas is made by written document and is subject to commercial registration. As a rule, it requires the company’s consent, except where the transfer is made to a spouse, ascendants, descendants or another shareholder. If the company refuses consent, it must generally propose the redemption or acquisition of the quota; if it does not, the transfer becomes free.
The system protects shareholders against the entry of outsiders, but slows down investor entry. In addition, shareholders and their quotas appear in the permanent certificate, which anyone may consult.
In an SA, shares are freely transferable. The articles may subject transfer to company consent or pre-emption rights, but may not exclude transfer altogether. Registered certificated shares are transferred by declaration on the certificate and registration with the company; book-entry shares are transferred by registration in the relevant account. Shareholders do not appear in the commercial register, which ensures greater privacy over the capital structure.
In both cases, beneficial owners must be declared in the Portuguese Central Register of Beneficial Owners (RCBE) within 30 days of incorporation and after any change. For projects involving investment rounds, share plans for managers or a planned sale, the SA makes the process significantly easier.
There are few differences here. Both an Lda. and an SA are subject to the same corporate income tax regime. In 2026, the general rate is 19% and SMEs benefit from a 15% rate on the first 50,000 euros of taxable profit, plus municipal and state surcharges where applicable. Both follow the Portuguese Accounting Standardisation System, need a certified accountant and file the same returns, such as the IES and SAF-T file. This analysis should be integrated into a broader review of tax planning and compliance.
Dividends are taxed in the same way, regardless of the corporate form. For many years there was a relevant difference in transfer tax: the purchase of quotas in companies holding real estate could be taxed as if the real estate itself had been purchased, while the purchase of shares was not. Since 2021, the rule applies to both forms where more than 50% of the company’s assets consist of real estate located in Portugal, not allocated to agricultural, industrial or commercial activity, and one shareholder comes to hold at least 75% of the share capital. The cost difference between the two forms therefore lies mainly in the governance structure required by the SA.

There is no abstractly better corporate form. The choice depends on who the shareholders are, how much capital they will invest and, above all, what they expect to happen to the company over the next five to ten years.
The Lda. tends to be the most suitable option when:
The SA makes more sense when:
The decision is not final. An Lda. may be converted into an SA, provided that the requirements relating to capital and number of shareholders are met. It is common to start as an Lda. and convert when the first external investor enters.

An Lda. is usually more suitable for structures with a small number of shareholders and greater control over the entry of third parties into the share capital. An SA tends to be more suitable for projects with greater capitalisation, several shareholders, investor entry or a clearer separation between ownership and management.
An Lda. may be incorporated by two shareholders or by a single shareholder, in which case it is a single-member quota company. An SA generally requires five shareholders, although it may have a single shareholder where that shareholder is a company.
In an Lda., the share capital is freely set by the shareholders, with a minimum of 1 euro per quota. In an SA, the minimum share capital is 50,000 euros, and part of the cash contributions may be deferred under the applicable legal rules.
As a general rule, an Lda. has a simpler structure and lower running costs, particularly because supervision is usually optional. However, the choice should depend on the number of shareholders, governance model, expected investor entry and growth plan.
An SA may make more sense when investor entry, financing rounds, a significant number of shareholders, a future sale or a clear separation between ownership and management are expected.
In an Lda., shareholders and their quotas appear in the permanent certificate. In an SA, shareholders do not appear in the commercial register, although beneficial owners must be declared in the Portuguese Central Register of Beneficial Owners (RCBE).
The tax differences are limited. As a rule, both an Lda. and an SA are subject to the same corporate income tax regime, accounting obligations and tax treatment of dividends.
Yes. An Lda. may be converted into an SA if the applicable requirements are met, including capital and number of shareholders. It is common to start as an Lda. and convert the company when an external investor enters.
