OÜ (private limited) is the standard structure, formed online via e-Residency or in person. Reporting obligations are real but proportionate; accounting partners are widely available.

SRL (limited liability) is the standard structure. Formation involves notary and trade registry. Microcompany tax regime may apply for small businesses with eligible activities.

SA de CV (Sociedad Anónima) and S de RL de CV are the standard private entity types. Formation involves a notary, RFC (tax registration), and IMSS where staff are involved. Mexican tax residency is triggered by primary home and centre of economic interests.

SRL (Limited Liability) and SA (Joint Stock) structures are available; entity setup is well-supported by local partners. Substance and reporting requirements should be confirmed at setup.
