GmbH and UG (haftungsbeschränkt) are common structures. Notary involvement is required for formation. Tax registration, trade registration (Gewerbeanmeldung), and German GAAP / tax accounting standards apply.

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.
