The Portuguese Lda (Sociedade por Quotas): the complete guide

What is a Sociedade por Quotas?

The Sociedade por Quotas is one of the legal forms set out in the Portuguese Commercial Companies Code (Código das Sociedades Comerciais) for incorporating a company in Portugal. It is the form chosen by the vast majority of small and mid-sized Portuguese companies. The name reflects two essential features: capital is divided into quotas (assigned to each partner), and, as a rule, the company’s own assets answer for its debts; the partners’ only obligation is to pay in the share capital they subscribed (the value of their quotas). Hence the legal abbreviation Lda, from Limitada.

In practice, this means partners’ personal assets are, as a rule, kept separate from the company’s. The company’s creditors act against the company’s own assets, not against the partners’ homes, cars, or personal savings. There are important exceptions (manager liability for negligent management; specific regimes for tax and social-security debts), but the general principle is asset separation.

An Lda can be set up with two or more partners. When there is only one, the right form is a Sociedade Unipessoal por Quotas (single-partner Lda), which shares most rules with the standard Lda but has specifics, particularly around contracts between the sole partner and the company.

If you have run companies elsewhere, an Lda is roughly equivalent to a US LLC, a UK Ltd, a German GmbH, or a Spanish S.L.: limited liability, capital divided into shares/quotas, and a private structure suitable for closely held businesses.

What kind of business is it right for?

The Lda is the default legal form for most businesses in Portugal. It makes particular sense when more than one person is involved, when you want to separate personal and business assets, or when you intend to grow and professionalise the structure over time. For a freelancer just starting out, with low debt exposure and low revenue, individual self-employment (Empresário em Nome Individual, ENI) can be simpler. For a one-person business that wants limited liability from day one, or that is growing into a structure where a company form makes sense, the Sociedade Unipessoal por Quotas is usually preferable. The choice between ENI and Unipessoal also has tax-regime implications (regime simplificado vs contabilidade organizada) and longer-term considerations, and is worth discussing with a Portuguese certified accountant before committing. For the full comparison detail (personal liability, tax regime, bookkeeping, Social Security, costs, and decision criteria), see the dedicated guide: Sole trader (ENI) vs Portuguese Lda: which is right for your business?.

The table below summarises the main differences between the most common forms:

The choice between these forms is strategic and tax-driven. It’s worth speaking with a Portuguese certified accountant (contabilista certificado) before committing, especially around the right tax regime (regime simplificado vs contabilidade organizada, IRS vs IRC).

Who are the partners, the managers, and the partner-manager?

In an Lda there are three roles to distinguish, even when they overlap in the same person: partners (sócios), managers (gerentes), and the partner-manager (sócio-gerente).

Partners hold the quotas and, through them, own the company. They are entitled to share in profits, to vote at general meetings, and to exercise all other rights set out in the articles of association and the law. They have no automatic role in day-to-day management.

Managers run the company and represent it to third parties. They are appointed by the partners (in the articles, at incorporation, or in a later general meeting) and may or may not be partners themselves. They have fiduciary duties to the company, can be held personally liable for negligent management, and answer for tax and social-security debts that come due during their tenure, under the conditions set by law.

The partner-manager is the most common figure in practice: someone who is at once a partner (holds a quota) and a manager (runs the company). It is the typical founder-operator configuration, and the standard structure for a small Lda.

Share capital and quotas

Since 2011, the minimum share capital for an Lda has been €1 per quota: €2 for a two-partner Lda, €1 for a single-partner version. The reform removed the previous €5,000 minimum, but share capital still matters: it is the basis of limited liability and the amount partners can be called to contribute.

Capital can be paid in cash or in kind (assets), and can be fully subscribed and paid at incorporation or deferred under the law’s conditions. New companies often subscribe a symbolic capital (€50 to €1,000) to minimise risk, although this can affect how banks and suppliers perceive the company.

Each partner holds a quota with a nominal value reflecting their share of the capital. Quotas can be transferred (sold, gifted, inherited) under whatever rules the articles of association or the law set out.

How to set up a Sociedade por Quotas

Incorporating an Lda in Portugal is, today, fast and straightforward. The State offers two main paths: Empresa na Hora, in-person at an Espaço Empresa counter or Conservatória, and Empresa Online, fully digital. The choice is a trade-off between speed (Empresa na Hora is immediate) and flexibility (Empresa Online allows articles drafted by the partners). As an alternative, incorporation can also be done at a notary office, which is usually more expensive and used in specific cases.

1. Choose the company name (firma). The name must be admissible: it cannot be confused with already-registered names and cannot use protected terms without entitlement. Names can be searched and reserved at the National Registry of Legal Persons (RNPC) via the Justice portal.
2. Define the articles of association (pacto social). The articles are the company’s “contract”: they define the corporate purpose, capital, quotas, management, and operating rules. For fast incorporations there are pre-approved articles available on both paths; for companies with specifics (special clauses, manager binding rules, quota transfer rules), Empresa Online allows articles drafted by the partners, ideally with legal support.
3. Incorporate. Through Empresa na Hora, this is in-person and the company is incorporated the same day, often in under two hours, using pre-approved articles. Through Empresa Online, this is done 100 % online with authentication via Chave Móvel Digital or Cartão de Cidadão; after filing, the Conservatória reviews and registers the company in around 5 working days (pre-approved articles) or 10 working days (partner-drafted articles), assuming no objections.
4. Get the company tax ID (NIPC). At incorporation, the company receives its Número de Identificação de Pessoa Coletiva (NIPC), which doubles as its NIF (tax ID).
5. File the start-of-activity declaration with the tax authority. Required within 15 days of incorporation, filed by a certified accountant through the Portal das Finanças. Sets the VAT regime, the CAE (economic activity code), and other tax parameters.
6. File the RCBE. The Registo Central do Beneficiário Efetivo identifies the people who, ultimately, control or benefit from the company. The initial filing is mandatory; periodic confirmations follow.
7. Subscribe to the Certidão Permanente. At incorporation, the company is automatically issued a Certidão Permanente access code valid for three months, free of charge. After that, to keep third parties (banks, clients, suppliers) able to consult the company officially, the access code can be subscribed for 1, 2, 3, or 4 years (with a progressive discount on longer terms), starting from around €25 per year.

Setup and ongoing costs

In 2026, Empresa Online costs €220 with pre-approved articles of association or €360 with articles drafted by the partners (one-off fee covering incorporation, commercial registry, and publication). Empresa na Hora generally costs around €360. Additional fees may apply, for example if a trademark is registered in the same act.

Recurring annual costs include:

• Certidão Permanente subscription: ~€25 per year.
• Accountant fees: a certified accountant’s fees vary, typically €100 to €400 per month for a small SME, depending on volume and complexity.
• Taxes and contributions: IRC (corporate income tax), VAT, withholdings at source, Social Security. Vary with activity and revenue.
• Occasional fees: changes to the articles, certificates, registrations.

On tax regime, the standard IRC rate for 2026 is 19 % (mainland), with reduced rates for SMEs on the first tranches of taxable income. There is also Autonomous Taxation on certain expenses (vehicles, entertainment, per diems), at rates that depend on the type of expense and the fiscal result.

Essential company documents

A handful of documents accompany an Lda from day one and need to be kept current and accessible:

• Articles of association (pacto social). The founding document. Every change (registered office, management, capital, corporate purpose) creates a new version.
• Minutes book (Livro de Atas). Records partners’ and managers’ resolutions. Includes annual general meeting minutes (accounts approval), manager appointment/replacement minutes, and other relevant decisions.
• RCBE. Identifies beneficial owners. Must be kept current.
• Certidão Permanente. Not strictly a company document, but the access code is operationally important: it’s what third parties use to consult the company in real time.
• Accounting documents. Invoices issued, expense receipts, bank statements, tax filings. Must be kept for the legally required period (generally 10 years for tax purposes).

Keeping all of this organised is, in part, the problem Limitada exists to solve: every document has its place, with versions, dates, and authors, and access can be shared with the accountant without an email back-and-forth.

Tax and legal obligations (overview)

An active Lda has a recurring set of tax and legal obligations. This is the high-level view; for the complete, month-by-month calendar with every deadline, see A Portuguese Lda’s tax and legal calendar (2026).

• IRC (corporate income tax): annual return on the Modelo 22 form, filed by 31 May of the year after the fiscal year. There are also instalments in July, September, and December.
• VAT: depending on the regime (quarterly or monthly), periodic filings on their own schedule.
• IES (Simplified Business Information): annual filing due by 15 July of the following year.
• Withholdings at source: monthly, due by the 20th of the following month.
• Social Security: monthly remuneration declaration and payment due by the 20th.
• Annual accounts and approval: accounts must be approved at a general meeting by 31 March of the following year (as a rule) and filed with the IES.
• RCBE confirmation: periodic, with deadlines set by the current legislation.

The accumulation of these obligations is probably the single biggest source of administrative noise in an Lda’s life. Centralising deadlines in one place, with alerts before each one, is one of Limitada’s core features.

Changes during the company’s life

A Lda rarely stays the same. Over time, it’s common to see:

• Registered office changes. A change of formal address. Requires an amendment to the articles and a registry filing.
• Partners joining or leaving. Quota transfers, subject to the articles and the law.
• Capital increases or reductions. Through new funds, conversion of shareholder loans, or other reasons.
• Management changes. Manager appointments or removals.
• Changes to the corporate purpose. As the company diversifies or refocuses.

Each of these changes requires general meeting or management minutes, a registry filing (as a rule), and, in many cases, an updated RCBE declaration. Each specific section has, or will have, dedicated guides for the concrete process.

Dissolution and wind-down

An Lda can end its life through voluntary dissolution (a partner resolution), administrative dissolution (in certain legal situations), insolvency, or merger/de-merger with another entity. Dissolution involves the resolution, liquidation of assets, settling final tax obligations, and cancelling the registration. A dedicated guide on this topic will follow in the The Portuguese Lda section.
