The Servicio de Administración Tributaria (SAT) in Mexico is reminding all companies (personas morales) that the deadline for submitting their annual tax declaration is rapidly approaching. March 31, 2025, marks the final day for businesses to report their financial and fiscal operations from the previous year. This mandatory filing is critical for compliance and avoiding potential penalties.

Why is This Declaration Important?

The annual declaration provides the SAT with a comprehensive overview of a company's financial health and tax obligations. Vanesa Rojas (2025), writing for El Imparcial, emphasizes the importance of meeting this deadline to avoid substantial fines. Failure to comply can result in penalties ranging from $1,810 to $44,790 pesos, as noted by Rojas, along with potential surcharges for inflation and delays, according to the Código Fiscal de la Federación 2025.
