S.A. de C.V. or S. de R.L. de C.V.? Incorporating Your Mexican Subsidiary
The two entity types virtually every foreign investor chooses between, the differences that actually matter, and the incorporation checklist end to end.
The two workhorses
Nearly every foreign-owned subsidiary in Mexico is either a Sociedad Anónima de Capital Variable (S.A. de C.V.) or a Sociedad de Responsabilidad Limitada de Capital Variable (S. de R.L. de C.V.). Both offer limited liability, both require a minimum of two shareholders or partners, both allow 100% foreign ownership in most economic activities, and neither has a meaningful statutory minimum capital — capital is set in the bylaws.
The differences that actually matter
The S.A. issues shares (acciones), transfers more freely, and is the natural vehicle if you ever contemplate multiple investors or equity incentives. The S. de R.L. issues partnership interests (partes sociales), caps its members at fifty, and restricts transfers — features that make it feel closer to an LLC. US-parented groups very often choose the S. de R.L. because it can qualify for pass-through (check-the-box) treatment under US tax rules; that decision should be made with your US tax advisor, not by default.
The incorporation checklist
The sequence: authorization of the corporate name from the Ministry of Economy; drafting of bylaws — including the foreign-investment admission clause — and execution of the incorporation deed before a Mexican notary; registration with the Public Registry of Commerce; tax registration (RFC) before SAT and designation of a legal representative; registration before the National Registry of Foreign Investment (RNIE) within the statutory period; corporate books; and the bank account. With apostilled powers of attorney and documents ready, the process typically runs a few weeks — the pacing items are usually notary schedules and SAT appointments, which vary by city and season.
What the foreign shareholders must prepare
Corporate shareholders need existence and representation documents apostilled or legalized and officially translated; individuals need passports and, in both cases, powers of attorney granted for the incorporation. No Mexican partner is required. A handful of sectors remain restricted or capped for foreign investment under the Foreign Investment Law — worth checking early if you operate near transport, energy or media.
After the deed: the obligations that start immediately
Incorporation is the beginning, not the end: monthly tax filings begin, the entity must keep beneficial-controller records available to SAT under rules in force since 2022, and hiring the first employee triggers employer registrations. Budget for compliance from month one — it is far cheaper than remediating later.
