Entity types, registration process, required documents, costs, and official registries.
Quick answer
Companies (commonly a Sociedad Anónima or the simpler SAS) are formed before a notary and registered in the Public Registry of Commerce; a tax ID (RFC) from SAT is required. The online SAS route suits small businesses.
Mexico company setup usually combines corporate formation before a notary or the simplified company system, inscription in the Public Registry of Commerce, and tax registration with SAT for an RFC and e.firma.
- Common operating forms include the S. de R.L. de C.V., S.A. de C.V. and, for qualifying small founders, the Sociedad por Acciones Simplificada (SAS).
- Secretaría de Economía describes formation steps including economy-ministry formalities, notary steps, Public Registry of Commerce inscription and RFC registration.
- SAT requires legal-entity documentation, fiscal domicile evidence and representative authority for RFC/e.firma processes.
Step-by-step
- 1
Choose the company type
The sociedad de responsabilidad limitada (S. de R.L.) and the sociedad anónima (S.A. de C.V.) are the common forms; a simplified online SAS is available for smaller companies via the federal portal.

Request a name authorisation (autorización de denominación) from the Ministry of Economy (Secretaría de Economía).
