Mexico Tax Surveillance Online Becomes Operational

White & Case – As part of the Tax Reform that became effective on January 1, 2014, the Mexican Congress passed a series of amendments to the Federal Tax Code with the purpose of modernizing and facilitating the compliance and enforcement of tax obligations.

Such amendments gave tax authorities a tremendous surveillance power over taxpayers, which we believe is contrary to human rights and legal certainty.

human rights of privacy and legal certainty.
As of June 30, 2014, Federal Tax Authorities in Mexico (“SAT”) may communicate with
corporate taxpayers electronically by sending emails to a personal inbox kept in SAT’s
website called the Tax Inbox (
buzón tributario
That seems to be perfectly in line with modern forms of communication. However, when
a taxpayer considers that SAT may serve all kinds of notices through the Tax Inbox, including
notices of deficiency, initiation of audits, imposition of penalties or any other, some concerns
start to arise.
Those concerns may become real issues when the Tax Inbox is considered in connection
with a new obligation of keeping accounting records electronically.
Along with the provisions creating the Tax Inbox, Congress passed certain amendments
obliging taxpayers to submit their accounting records electronically through SAT’s website
pursuant to certain rules that SAT was going to publish.
On July 4, 2014, such rules were issued by SAT and published in the
Official Gazette
and on
July 11, 2014, some forms that were referred to in such rules were also published.
As a consequence of the foregoing, taxpayers are now obliged to submit their accounting
records to SAT on a monthly basis without any further formality required from SAT.
We believe that the provisions obliging taxpayers to submit their accounting records
electronically on a monthly basis are contrary to human rights of privacy and legal certainty,
and that taxpayers may challenge such provisions with reasonable chances of success.
