The S.A. de C.V. and the Simplified Joint-Stock Company (S.A.S.) both limit, in principle, the liability of their shareholders, but they respond to different needs. In 2026, the S.A.S. retains advantages of digital, low-cost incorporation, along with limits on shareholders and income. The S.A. de C.V. requires more formality, but offers greater breadth for investment and corporate governance. The choice must be based on the real project, not just on the speed of opening.
What each entity offers
The S.A.S. may be incorporated by one or more individuals through the electronic system of the Ministry of Economy, without a public deed being a mandatory requirement. Each shareholder needs an e.firma and one of them must have a name authorization. In contrast, the S.A. requires at least two shareholders, formalization before a public official and a structure with a sole administrator or a board and oversight through a statutory examiner. Adding "de C.V." allows the variable portion of the capital to be modified in accordance with the bylaws and the law, but it does not eliminate the general formalities. The S.A. de C.V. usually allows more detailed bylaws for classes of shares, transfer, voting, administration and deadlock resolution.
The special limit of the S.A.S. in 2026
For 2026, the total annual income of an S.A.S. cannot exceed 7,678,849.94 pesos, an amount updated by the Ministry of Economy. If it exceeds this, it must be transformed into another corporate regime. In addition, shareholders can only be individuals and cannot simultaneously control another commercial company under the terms provided by law. These restrictions make the S.A.S. useful for small businesses with simple ownership, but they may be incompatible with an investment round, a holding company as a shareholder or accelerated growth. The amount is a corporate limit, distinct from the requirements to be taxed under a given tax regime.
The decision must look three years ahead
The right form depends on who will invest, how much revenue is expected, how decisions will be made and what banks, clients or investors will require. An S.A.S. may be efficient when there are few individual founders, simple operations and a need to start quickly. An S.A. de C.V. is usually more functional when corporate-entity investors, differentiated rights, a board, institutional financing or sophisticated agreements are anticipated. Maintenance costs, reporting obligations, future transformations and exit rules must also be compared. Before incorporating, it is advisable to design a projected capitalization table and simulate two scenarios: growth within the S.A.S. limit and expansion that requires transforming the company.
