Differences between stock corporations,LLCs, and SAS

This article aims to explain to the reader the main differences in the regulation of limited liability companies (LLCs), stock corporations (SA), and the new simplified corporations or simplified joint-stock company (SAS), introduced by the recent “Law for the Promotion of Entrepreneurship” No. 19.820.

The objective is to provide the reader with a comparative understanding of the main characteristics of each company type, enabling them to select the one that best suits their operations or business project.


1. ⏳ Term

  • In both SAS and stock corporations, a term exceeding 30 years can be established.
  • In LLCs, the term cannot exceed 30 years with the possibility of renewal.

2. 🎯 Corporate Purpose

  • SA and LLC: The articles/memorandum of association must clearly establish the activities the company will carry out.
  • SAS: Its articles of association may define an indeterminate corporate object: “any lawful activity“, avoiding the need for frequent amendments.

3. 👥 Number of Members or Shareholders

  • SA and LLC: Require two or more individuals or legal entities to incorporate.
    • SA: Only one shareholder may remain after incorporation.
    • LLC: Must always have at least two and no more than 50 shareholders.
  • SAS: A single shareholder may incorporate the company and remain in this form for the entire life of the company (unipersonal).

4. 💰 Capital Contributions

  • SA: At least 25 % of the authorized capital must be paid in at incorporation.
  • LLC: At least 50 % of cash contribution and 100 % of in-kind contributions must be subscribed/paid in at signing; they have 2 years to pay the remaining cash capital.
  • SAS: 10 % of cash contribution and 100 % of in-kind contributions must be paid in at incorporation; they have a term of 2 years to pay the remaining amount.

5. 🗳️ Vote per Share and Share Premium

  • Vote per Share: In LLCs and SA, each share/interest is entitled to one vote. In the SAS, single or multiple votes may be attributed to different classes of shares (flexibility).
  • Share Premium: An important innovation of the SAS is that it allows different share premiums within a single share issue. This is expressly prohibited for SA and LLC.

6. 🔄 Transfer of Shares

  • SAS: Bylaws can stipulate restrictions on the sale of shares that even imply a prohibition on sale for up to a maximum period of 10 years.
  • SA: Transfer of shares is free, although restrictions that do not imply a prohibition to sell may be provided for.
  • LLC: Transfer to third parties requires approval of 75 % or unanimity (depending on the number of members).

7. 📍 Venue of the Members’/Shareholders’ Meeting

  • SAS and LLCs: Meetings must be held at the company’s registered office.
  • SAS: Shareholders’ meetings can be held in any location where shareholders can participate (increased flexibility).

8. 🚫 Exclusion of Members or Shareholders

  • SA: No possibility of excluding a shareholder.
  • LLC: Members may be excluded for serious noncompliance.
  • SAS: Provides for the possibility of establishing the exclusion of the minority shareholder (holding up to 15 % of the issued shares) in the bylaws.

9. 📜 Enforceability of Partnership Agreements against the Company

  • LLC: Partnership agreements are not enforceable against the company.
  • SA: Enforceable only if certain requirements are met.
  • SAS: Agreements delivered to the offices where the administration operates shall be enforceable against the company (greater legal certainty).

10. 🛡️ Liability of Members or Shareholders for Labor and Tax Obligations

  • SAS and SA: Shareholders’ liability is limited to their contributions, without exception (unless fraud/abuse).
  • LLC: Partners’ liability is also limited to contributions, with two exceptions: they are jointly and unlimitedly liable for debts of a salary nature and for the payment of the Tax on Income from Economic Activities (IRAE).
  • Representatives: They may be held jointly and severally liable for tax debts (including IRAE), even if they have not acted negligently or with fraudulent intent.

11. 🏦 Inform about Holders and Beneficial Owners to the Central Bank of Uruguay
