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.
The consequences go far beyond a fine:
- Tax: tax credits, surcharges, inflation adjustments and penalties.
-
Administrative: loss of deductions, denial of tax refunds, cancellation of digital tax stamps and fiscal or foreign trade authorizations.
- Criminal: potential tax crimes under Mexican law.
