U.S. companies expanding into Mexico almost always start with the same question: what kind of legal entity should we form? The answer shapes your taxes, your liability, your governance, and how cleanly the Mexican operation plugs into your U.S. structure.
What entity types can a U.S. company use in Mexico?
Two vehicles cover the vast majority of foreign-investment scenarios:
- S.A. de C.V. (Sociedad Anónima de Capital Variable) — a stock corporation. Ownership is represented by shares, governance runs through a board or a sole administrator, and it is the familiar choice for larger operations or anything that may raise capital.
- S. de R.L. de C.V. (Sociedad de Responsabilidad Limitada de Capital Variable) — a limited liability company. Ownership is held in partes sociales (membership interests) rather than shares, with a capped number of partners.
Both offer limited liability and both allow variable capital (the “de C.V.” part), which makes increasing or decreasing capital far simpler.
Which one should you choose?
For many U.S. parents the S. de R.L. de C.V. is the default, for one big reason: it can generally be treated as a pass-through (a disregarded entity or partnership) under U.S. “check-the-box” rules, which often simplifies U.S. tax consolidation. The trade-off is a limited number of partners and interests that are less freely transferable.
The S.A. de C.V. is the better fit when you expect outside investors, multiple share classes, or a future transaction where freely transferable shares matter.
The right answer depends on your U.S. tax position and your plans for the Mexican entity — which is exactly why entity choice should be made with both U.S. and Mexican counsel in the room, before incorporation.
Can a U.S. company own 100% of the Mexican entity?
In most sectors, yes. Mexico’s Foreign Investment Law permits 100% foreign ownership across the large majority of industries. A limited set of activities is reserved or restricted, so confirm your specific sector before you file.
What about a holding structure?
Many groups place the Mexican operating company under a U.S. or third-country holding company to centralize ownership, simplify future M&A, and manage treaty positions. This is a decision to make up front; restructuring ownership after the entity is live and operating is slow and can trigger tax friction.
The takeaway
Entity selection is the first domino in a Mexican build-out, and it touches tax, governance, and exit options all at once.
