How electronic accounting requirements work in Mexico

key implementation dates

The electronic accounting framework in Mexico has been in place for years and was introduced through a gradual rollout. These milestones show how Contabilidad Electrónica became part of the country’s long-term tax control model.

01/07/2014

From July 2014, Mexico introduced the obligation for certain taxpayers to keep accounting records in electronic form and begin sending accounting information to the SAT. This marked the start of the country’s electronic accounting model and laid the basis for the technical structure later reflected in Anexo 24.

01/01/2015

From January 2015, the phased implementation of electronic accounting obligations became effective for key taxpayer groups, including financial institutions and certain legal entities. SAT rules from that period show that compliance was introduced in stages depending on taxpayer type and income level.

Current model

Contabilidad Electrónica remains in force in Mexico as part of the SAT’s wider tax compliance framework. The current Anexo 24 continues to define the structure and content of the required accounting files, including the chart of accounts, trial balance, journal entries, and supporting records in XML format.
