SA, SAS or SRL: The Right Form for a Family Holding
For a multi-generational holding, speed of incorporation is not the relevant variable. Where the SAS needs more care than the generic guides suggest.
The Simplified Joint-Stock Company (SAS) has become, in recent years, the form most recommended by generic content on “opening a company in Uruguay” — fast, digital, cheap to incorporate. And for a real share of cases, it is indeed the right choice.
But treating it as a universal answer ignores that the SA, the SRL and the SAS serve different logics — and that, for a family wealth holding specifically, speed of incorporation is rarely the most relevant variable.
The three forms, and what each one is
Sociedad Anónima (SA). Uruguay’s classic corporate form, governed by Law 16,060. Capital represented by shares, mandatory oversight from incorporation, and the only type permitted to make a public offering of shares. Historically preferred for larger operations and structures needing consolidated international recognition.
Sociedad de Responsabilidad Limitada (SRL). A simpler structure, with quotas instead of shares, a life limited to 30 years (extendable), and no mandatory oversight from incorporation — except where all members and ultimate beneficiaries are individuals, in which case certain controls are waived.
Sociedad por Acciones Simplificada (SAS). Created by Law 19,820/2019 and regulated by Decree 399/019, with the stated aim of promoting entrepreneurship. It can be incorporated by a single person, allows incorporation by digital means with model articles and, in most cases, without a public deed. It falls under oversight by the national internal audit office only above annual revenue of 37,500,000 UI.
The decision matrix, side by side
| Criterion | SA | SRL | SAS |
|---|---|---|---|
| Legal basis | Law 16,060 | Law 16,060 | Law 19,820 + Decree 399/019 |
| Minimum capital paid in at incorporation | 25% subscribed, 50% paid in, no deadline to reach 100% | Payment per the members’ agreement | Flexible, set in the articles |
| Single member from incorporation | No | No (general plurality rule) | Yes, throughout its existence |
| Digital incorporation, no public deed | No | No | Yes, in most cases |
| Mandatory oversight from incorporation | Yes | No, save exceptions | Only above annual revenue of 37,500,000 UI |
| Duration | May exceed 30 years | Up to 30 years, extendable | May exceed 30 years |
| Public offering of shares | The only type permitted | No | No (but may issue negotiable debt) |
| International / banking perception | Historically the most consolidated | Intermediate | Still consolidating — the most recent in the market |
Where the SAS genuinely stands out
For someone starting an operation, testing a business model, or needing speed and low incorporation cost, the SAS is today the most efficient of the three — particularly for a single member, with wide contractual freedom to define the company’s internal organisation, which favours quick amendments to the articles as the business evolves.
Where the SAS needs more care than generic content suggests
Perception among banks and international counterparties. As the most recent of the three structures in the Uruguayan market, some banks and international counterparties still apply a more conservative review process to the SAS than to the historically more established SA — a point rarely mentioned in guides promoting the SAS as the automatic choice.
Non-resident members and bank accounts. Non-resident shareholders of a Uruguayan SAS need a personal Uruguayan bank account to pay in subscribed capital and to receive dividends — which reintroduces, in practice, precisely the dependency on opening a bank account that fast incorporation alone does not resolve.
Long-term, multi-generational wealth holdings. For a structure meant to last decades, pass through successions and be recognised without friction by banks, auditors and international counterparties across generations, the SA’s historical robustness and established recognition still weigh in its favour — even with a more formal incorporation process.
Note on scope: banking perception of the SAS has been improving as the structure has consolidated in the market since 2019, and the picture may already be more favourable than described here by the time this article is read. We confirm the current policy of the specific bank or counterparty before choosing a corporate form on that criterion alone.
By objective, not by fashion
- To run an active operation, with speed and low initial cost: the SAS is generally the most efficient choice — particularly for a single member or a small group.
- For a long-term family wealth holding, with multiple heirs and a multi-generational horizon: the SA usually offers more predictable institutional recognition, albeit at the cost of a more formal incorporation process.
- For an intermediate structure, with defined members and no need to raise capital publicly: the SRL remains a balanced option, particularly where all members and ultimate beneficiaries are individuals — in which case certain controls are waived.
None of the three is, in isolation, “the best corporate form in Uruguay” — each answers a different objective.
What this changes for anyone deciding
- Start from the objective, not from the form most recommended in generic content. “SAS because it is faster” is a valid answer for an active operation, and an incomplete one for a multi-generational wealth holding.
- Weigh the banking perception of specific counterparties, not only the law. The formal robustness of each structure on paper does not always match, today, the practical familiarity banks and international auditors have with it.
- Do not decide the corporate form separately from the banking question. A non-resident member of an SAS or SA needs a personal Uruguayan bank account either way — plan that step alongside incorporation, not after it.
Frequently asked questions
Is the SAS always the cheapest and fastest option?
As a rule, yes, for initial incorporation — particularly because it allows a single member and a digital process. But the total cost of a structure also includes banking and institutional perception over time, not just the cost of setting it up.
Is an SA mandatory for larger operations?
Not mandatory by law, but historically it is the option with the most established institutional recognition — which can weigh in its favour for larger operations or multi-generational horizons.
Can a foreign investor be the sole shareholder of an SAS?
Yes, both individuals and entities, resident or non-resident, may be shareholders — but non-resident shareholders need a personal Uruguayan bank account to pay in capital and receive dividends.
Can an SRL or SA be converted into an SAS later?
Uruguayan law allows pre-existing companies to convert into an SAS under certain conditions — but publicly held companies face specific restrictions in that process.
The starting point
The right question is not “which corporate form is best in Uruguay” — it is “which corporate form serves my specific objective: operating, investing, or structuring family wealth across generations”. The three answers are different.
If you are considering opening a company or a holding in Uruguay, it is worth mapping the real objective before choosing a structure on speed of incorporation alone.
One conversation is enough to design that choice precisely.
