Mexico: Tax authorities intensify payroll tax enforcement efforts

An increase has been observed in the issuance of tax notices, invitation letters, and requests of tax regularization concerning alleged omissions in payroll tax compliance. Generally, these communications stem from cross checked tax information conducted with other tax authorities and commonly include an estimated assessment of supposed payroll tax liabilities, together with related surcharges and penalties, as well as the reference for the payment. These notices also warn taxpayers of the potential initiation of audit and verification procedures and, where applicable, the imposition of penalties.

Implications for companies

These actions confirm a broader trend among local tax authorities toward strengthening tax audit and enforcement capabilities through the intensive use of information available in tax, labor, and social security databases.

Such enforcement mechanisms may be particularly relevant for multinational and multi-state business groups with decentralized hiring structures, multiple employer registrations, or operating models in which the administrative assignment of employees does not necessarily align with the actual location where services are rendered.

In this context, the primary focus of review is generally the proper determination of the state or jurisdiction in which payroll-related local taxes should be reported and payed, as well as consistency among the information filed before different governmental authorities.

Key areas companies should review

Upon receipt of these types of communications, companies are advised to assess, among other matters:

• The nature and scope of the notice received.
• The periods covered and the methodology used by the authority.
• The consistency between the company’s actual business operations and compliance with local tax obligations.
• The alignment among employer registrations, work locations, electronic payroll tax receipts (CFDI payroll vouchers), and other supporting documentation.
• The feasibility of pursuing a clarification, voluntary correction, regularization, or defense strategy, depending on the specific circumstances involved.

Recommendations for companies

Companies should carefully review any communication of this nature before adopting a position or making any payment, in order to properly assess its scope, the associated risks, and the available courses of action.

In particular, companies with operations in multiple states may benefit from conducting a preventive review of their operating model and compliance with local tax obligations to identify potential exposures and, where appropriate, define a remediation or risk mitigation strategy.

The receipt of these notices may signal broader reviews concerning local tax liabilities, especially for organizations with geographically dispersed operations, mobile workforces, or complex employment structures.

A timely review may help companies anticipate contingencies, validate the applicable territoriality criteria, and develop a consistent response before the potential commencement of formal tax audit procedures or the imposition of penalties.
