Since the SAS came along, the corporation is no longer the default choice. It remains the most solid form for large operations, but it is also the most expensive to set up and the heaviest to maintain. Here is what it is exactly, what sets it apart, and when it still beats an SAS.
What a corporation is
It is a commercial company in which capital is divided into shares represented by negotiable instruments, and each shareholder’s liability is limited to the amount invested in those shares. It has its own legal personality: the company’s assets are entirely separate from its shareholders’.
That is what defines it against the other forms: shares are transferred without touching the articles of association. Joining or leaving an SA is a transaction in securities, not a statutory amendment with a deed and registration, as it is in an SRL.
Main characteristics
- Limited liability to the capital contribution. Shareholders do not answer with personal assets for company debts.
- Share capital, in negotiable and transferable instruments.
- Legal personality independent of its shareholders.
- No cap on shareholders, and they may be individuals or legal entities, local or foreign.
- Formal corporate bodies: shareholders’ meeting, board or administrator, with the formalities the law requires.
- Capital is partially paid in at incorporation, with a legal period to complete it. Confirm the exact percentages and periods with your notary, because the real initial outlay depends on them.
The real advantages
Transferring ownership is simple
This is the most concrete operational advantage. Selling a percentage of the company, bringing in an investor or reorganising ownership is resolved by transferring shares. In an SRL each of those moves requires amending the articles.
Institutional signal
For certain counterparties — banks, tenders, international partners, investment transactions — the SA is still the expected structure. It is not a legal matter but one of perception, yet it is real and sometimes decisive.
Scale and corporate governance
When there are many shareholders, the formal structure of meeting and board stops being a burden and becomes what orders decision-making.

The drawbacks, plainly
- It is the most expensive to incorporate of the four Uruguayan company forms.
- Strict, recurring formalities: minutes, meetings, notices, corporate books. That means administrative cost and professional fees every year, whether you trade or not.
- It requires an initial capital outlay, unlike a sole proprietorship, which has no minimum.
- Oversized for most ventures starting out.
SA or SAS: the comparison that matters
This is the real decision today, because Law 19.820 created the SAS precisely as a lighter alternative to the corporation.
| SA | SAS | |
|---|---|---|
| Minimum shareholders | Depends on type | 1, permanently |
| Capital | Shares, with required initial payment | Shares, 10% paid in if in cash |
| Bodies | Meeting and board, strict formalities | One legal representative is enough |
| Recurring formalities | High | Low |
| Incorporation cost | Highest | Lower than SA |
| Registration | Classic registry route | Allows electronic registration |
The practical rule: if your operation does not need a meeting and a board, the SAS gives you the same for less money and less paperwork. The SA is justified when there are many shareholders, when formal governance adds value, or when a counterparty requires it.
How it is incorporated
- Bylaws by public deed before a notary, with the name, purpose, capital, structure of bodies and the company’s term.
- Initial payment of capital as required by the rules in force.
- Registration with the Public Commercial Registry and with the tax and social security bodies: DGI and BPS, plus the MTSS where applicable.
- Legal publications.
- Appointment of the bodies: board or administrator and, depending on the case, a statutory auditor.
It is also possible to acquire an already incorporated company — what is known in practice as a shelf company — which shortens start-up times.
Taxes
No advantage or disadvantage here: an SA is taxed the same as an SRL or an SAS, under the general regime — IRAE at 25% on business income, VAT on taxable transactions and Net Worth Tax at 1.5% where applicable, plus employer contributions to the BPS. Full detail in taxes in Uruguay.
Choosing an SA for tax reasons makes no sense: the difference lies in the structure, not the tax burden.
If you are a foreign national
There is no nationality restriction on being a shareholder or director of a Uruguayan SA. To operate you need a Uruguayan identity document, which means having started your legal residency and obtained the identity card. Corporate documentation from abroad must be apostilled or legalised and translated where applicable.
Frequently asked questions
What is a corporation (sociedad anónima)?
A commercial company with capital divided into negotiable shares, its own legal personality and shareholder liability limited to the amount invested.
What is the minimum capital to incorporate an SA?
Capital is partially paid in at incorporation, with a legal period to complete it. Confirm the current percentages and periods with a notary before setting your initial outlay.
What is the difference between SA and SAS?
An SAS can have a single shareholder permanently, needs only one legal representative and carries considerably lower formalities and costs. An SA requires a shareholders’ meeting and a board with strict formalities.
Is an SA worth it for a small venture?
Usually not. To start alone or with few partners, an SAS or a sole proprietorship gives you the same with less cost and less administrative load.
Does an SA pay more tax than an SRL?
No. Both are taxed under the general regime: IRAE, VAT and Net Worth Tax as applicable.
Can a foreign national be a shareholder or director?
