Mexico indicates changes to tax in electronic accounting

16 December 2014

The Mexican tax authority has announced various modifications and additions to the rules surrounding electronic accounting; our local experts give an overview.


Mexico's Tax Administration Service (SAT) has indicated it intends to make changes to the Tax Federal Code art. 28 / Rule I.; I.; I. & I.

Although the various modifications and additions to the rules surrounding electronic accounting outlined here have not been published by the Mexican government, their imminent approval is highly likely as they have been announced by the SAT via its website. The announcement also contained other amendments to Annex 3 and Annex 24 which relate to the Chart of Accounts and the Grouping code.

Electronic accounting

This refers to any records which are kept in electronic systems and are capable of generating xml files that are uploaded to the authorities on a regular basis.

Taxpayers must be able to generate the following files for submission:

  • Chart of accounts
  • Monthly trial balance
  • Year-end trial balance

They must also generate monthly journal entries, but the format is still under discussion. One opinion mentions that monthly journal entries should be delivered only when: SAT excise is proved faculties directly to taxpayer or third party, or the taxpayer requests a refund or makes an offsetting; the other one mentions that journal entries should be delivered on monthly bases. 

How must accounting information now be submitted?

The information must be filled in compressed files (zip) through the Tax Mailbox, in the menu “Electronic Accounting.”
