THE PROBLEM

Why do companies operating in Mexico need a preventive tax audit?

Mexico’s tax legislation grows more complex every year. The SAT (Mexico’s Tax Administration Service) now has automated tools that detect inconsistencies in real time — unreported income, improper deductions, incorrect VAT credits — before the company even knows there is a problem.

The most frequent irregularities detected by the SAT include: unreported income, improper deductions, incorrect application of tax incentives, improper VAT crediting, and failure to file tax returns.

Las consecuencias van mucho más allá de una multa:

  • Fiscal: créditos fiscales, recargos, actualizaciones y multas.
  • Administrativa: pérdida de deducciones, negativas de devolución, cancelación de sellos digitales y autorizaciones fiscales o de comercio exterior.
  • Penal: posibles delitos fiscales.

We know Mexico’s SAT from the inside. Our specialists have direct experience in the public sector, which allows us to not only anticipate audit criteria but to build proven strategies that deliver real results — because we know exactly what the authority looks for when it audits and how to respond.

The model:

We are not a firm that shows up when the SAT has already knocked on your door. We are with your company every month — reviewing, detecting and correcting — so that Mexico’s tax authority never finds something we haven’t already seen and addressed.
