Once a foreign group has decided to operate through an Argentine company rather than a branch, a second question follows immediately: which company. Argentine law offers three realistic candidates — the sociedad anónima (SA), the sociedad de responsabilidad limitada (SRL) and the sociedad por acciones simplificada (SAS).
Most comparisons available in English rank them by how fast and cheap they are to incorporate. For a foreign investor that is close to the least relevant criterion. Incorporation happens once. Governance, transferability and supervision are lived with for years. Here is the comparison that actually matters.
The short answer
For a foreign parent putting real capital into Argentina, the practical choice is between the SA and the SRL. The SAS is an excellent vehicle — but it was designed for a different user, and for reasons set out below it rarely survives contact with a corporate group’s requirements.
The SA: the default for anything institutional
The SA is the vehicle Argentine counterparties, banks and regulators expect to see when the business has scale or outside investors.
- Capital is divided into shares, which transfer without amending the by-laws and without a registry filing for each transfer. For a group that anticipates bringing in a partner, granting security over equity or eventually selling, this is the single most important structural difference.
- Governance is formal: a board, shareholders’ meetings, statutory books, published notices for certain acts.
- A statutory minimum capital applies, fixed in pesos by the Companies Act. Inflation has made the figure largely symbolic, and the registry’s practical focus is whether capital is adequate to the stated corporate purpose rather than whether it clears the nominal floor.
- Certain SAs fall under permanent state supervision — those making public offerings, exceeding defined capital thresholds, operating in regulated sectors or with a single shareholder, among others. Permanent supervision means the registry oversees the company throughout its life, not only at incorporation. This is a real ongoing cost and it is worth confirming before choosing the type.
The SRL: quieter, cheaper, harder to sell
The SRL is often the right answer for a wholly-owned operating subsidiary with no plans to bring in third parties.
- Capital is divided into quotas, not shares. Quotas are transferable, but the transfer is a more formal act than a share transfer and typically requires a registry filing. This is the SRL’s defining limitation: it makes the company awkward to sell in part, awkward to pledge and awkward to use in a staged investment.
- No statutory minimum capital. The Companies Act does not impose one; capital must simply be reasonable in relation to the corporate purpose.
- Management is by one or more gerentes, with fewer formal governance layers than an SA.
- It sits outside the permanent supervision regime in the ordinary case, which reduces recurring compliance cost.
One point that repeatedly matters and is almost never raised in Argentine-side advice: the SA and the SRL may be classified differently for tax purposes in the parent’s home jurisdiction. In some systems a limited-liability company of the SRL type can be treated as transparent while a share-capital company cannot. That distinction can outweigh every Argentine consideration on this page. Run the choice past your home-country tax advisers before instructing local counsel, not after.
The SAS: excellent design, difficult fit
The SAS was created by the Entrepreneurial Capital Support Act to give founders a fast, cheap, digital vehicle. On its own terms it succeeds: a low minimum capital pegged to two statutory minimum wages, incorporation largely online, no physical corporate books — the company keeps digital records instead — and no obligation to appoint a supervisory body.
Three things nonetheless make it a poor fit for most foreign groups.
It cannot be used where the business falls into certain regulated categories. The SAS is unavailable to companies in several of the categories that trigger permanent supervision, including public offerings. A company that grows into one of those categories has to convert into another type — a corporate event nobody plans for.
Its regulatory history has been turbulent. Between 2020 and 2024 the Buenos Aires registry layered on requirements the founding statute had not imposed — mandatory financial statements, guarantees from administrators, restrictions on how capital could be evidenced — and then reversed most of them in 2024. The rules are now favourable again. But a vehicle whose treatment has swung twice in five years is a difficult thing to build a fifteen-year investment on.
It does not save the foreign shareholder any work. A foreign parent holding SAS shares still has to register with the corporate registry to be a shareholder, exactly as it would for an SA or SRL. The SAS saves time for the company, not for the group behind it.
None of this makes the SAS wrong. For a founder-led venture, a joint development vehicle or an early-stage local operation, it can be the right call. It is simply not the default it is sometimes presented as.
Concrete legal risks ⚠️
Choosing the SRL and then trying to sell half of it. The quota transfer mechanics that seemed irrelevant at incorporation become the central friction in a transaction, adding time and registry dependency to a deal that is already time-sensitive.
Under-capitalising to save cost. Nominal minimums are low. Capital that is visibly inadequate for the declared corporate purpose invites challenge at registration and, more seriously, supports arguments to look past the corporate form when the company cannot pay.
Drifting into permanent supervision without noticing. Companies that cross a supervision threshold acquire recurring obligations. The trigger is the company’s own growth, and nobody sends a warning.
Choosing the SAS and outgrowing it. Conversion into another type is possible but is a full corporate reorganisation, with cost, timing and tax consequences, usually arriving at the worst moment — during a financing or a sale.
What to decide before incorporating 📌
- Map the five-year equity story. If anyone other than the parent may hold equity, default to the SA.
- Check the home-jurisdiction tax classification of each type before choosing.
- Confirm the supervision position for your sector, capital level and shareholder structure.
- Set capital against the corporate purpose, not against the statutory minimum.
- Draft the corporate purpose deliberately. Too narrow and it constrains the business; too broad and it invites registry questions.
- Remember the parent’s own registration. Whichever type you choose, the foreign shareholder must be registered before its votes can support registrable corporate acts — the subject of our note on ongoing compliance for foreign companies.
The strategic view
The three types are not tiers of quality. They encode different assumptions about who owns the company and what will happen to it. The SAS assumes founders who will run what they own. The SRL assumes a closed group that will stay closed. The SA assumes equity that will move.
Foreign investment almost always belongs in the third category, even when it does not feel that way on day one. The cost of choosing the wrong vehicle is not paid at incorporation. It is paid in the first transaction.
