Lda. vs S.A. in Portugal: Private or Public Limited Company?
The differences between a Sociedade por Quotas (Lda.) and a Sociedade Anónima (S.A.) in Portugal: capital, shareholders, governance, audit and costs.
Updated · 1 min read · By the GetLDA.pt team
Quick answer
An Lda. needs just €1 of capital per partner, one or more partners and simple management by gerentes. An S.A. needs €50,000 of capital, normally at least five shareholders (or one company), a formal board and a statutory auditor. For almost all startups and small businesses an Lda. is the right choice; an S.A. suits larger companies, share-based investment rounds and listings.
Portugal has two main types of limited-liability company: the Sociedade por Quotas (Lda.) and the Sociedade Anónima (S.A.). Both protect the owners' personal assets, but they are built for very different sizes of business.
Side by side
| Lda. | S.A. | |
|---|---|---|
| Minimum capital | €1 per quota | €50,000 |
| Owners | 1 or more partners (sócios) | Normally at least 5 shareholders, or a single corporate shareholder |
| Ownership units | Quotas | Shares (ações) |
| Transfer of ownership | By written contract, registered; often subject to partners' consent | Shares transfer more freely |
| Management | One or more managers (gerentes) | Board of directors, or a sole director for small S.A.s |
| Supervision | Statutory auditor only above certain size thresholds | Supervisory body / statutory auditor required |
| Running cost | Lower | Higher |
| Corporate tax | Same IRC rates | Same IRC rates |
When an Lda. is the better choice
- You're a founder, a small team or a family business.
- You want minimal capital and simple governance.
- Ownership changes will be rare and between known people.
That covers the vast majority of new companies in Portugal — which is why the Lda. is the default. It is also easy to convert an Lda. into an S.A. later.
When an S.A. makes sense
- You expect several investment rounds with many shareholders.
- You need freely transferable shares, or plan to list on a stock exchange.
- The business is large enough that a formal board and audit are expected anyway.
Conversion later
An Lda. can be transformed into an S.A. by resolution of the partners, provided the capital and governance requirements are met. Many Portuguese startups start as an Lda. and convert only when a larger funding round requires it.
