Corporate Compliance in Mexico: What You Need to Know
A Mexican S.A. de C.V. must hold an annual ordinary shareholders' assembly within four months of fiscal year-end, April 30 for calendar-year companies, to approve the prior year's financial statements and ratify or appoint administrators and comisarios. Three corporate books need to be maintained in Spanish and retained a minimum of ten years: the libro de actas de asamblea, the libro de registro de socios/accionistas, and, for capital variable entities, the libro de variaciones de capital. Legal representative changes, capital changes, address changes, and administrator appointments all need registration with the Public Registry of Commerce, since unregistered acts have no effect against third parties. Since a July 2025 LFPIORPI reform, a separate beneficiario controlador registration with the Secretaría de Economía is also required, distinct from SAT's existing beneficial-owner notice. If the sole legal representative resigns or becomes unreachable, a successor needs to be appointed promptly, since the administration organ is otherwise effectively paralyzed.
Key Requirements
Annual ordinary shareholders' assembly held within 4 months of fiscal year-end (April 30 for calendar-year companies), approving the prior year's financial statements and ratifying or appointing administrators and comisarios
Three corporate books maintained in Spanish and retained a minimum of 10 years: libro de actas de asamblea, libro de registro de socios/accionistas, and libro de variaciones de capital for capital variable entities
Registration of legal representative changes, capital changes, address changes, and administrator appointments with the Public Registry of Commerce, since unregistered acts have no effect against third parties
A separate beneficiario controlador registration with the Secretaría de Economía under the July 2025 LFPIORPI reform, distinct from SAT's existing Aviso de Socios, Accionistas y Control Efectivo
Prompt appointment of a successor if the sole legal representative resigns or becomes unreachable, since the administration organ is otherwise effectively paralyzed
Proper protocolization and registration of every capital contribution, including informal intercompany funding later capitalized, in the libro de variaciones de capital
Common Challenges
A parent company's board approval doesn't substitute for the local assembly
Some foreign owners treat approval at the parent's board level as sufficient corporate governance. Under Mexican law, a formal local assembly with proper minutes is still required regardless of sole-shareholder status, and skipping it is invalid, not just informal.
Unprotocolized minutes get rejected later, not immediately
Keeping informal, unsigned minutes in a binder feels harmless until a bank, notary, or counterparty needs to rely on a capital change or a representative appointment that was never properly protocolized and registered. The gap surfaces at the worst possible moment, not when it was created.
The 2025 beneficiario controlador registration is a new, separate obligation
Many advisors are still conflating this Secretaría de Economía registration with SAT's existing beneficial-owner notice. They are two distinct filings under different authorities, and treating the SAT filing as sufficient leaves the newer obligation unmet.
