SAT Electronic Audits: AI as a Tax Tool | Interview with Viviana Belaunzarán on Fórmula Financiera
Introduction
Digital tax enforcement is advancing rapidly, and SAT’s electronic audits are at the heart of this transformation. Our partner, Viviana Belaunzarán, was invited by MariCarmen Cortés, Marco Antonio Mares, and José Yuste to the program Fórmula Financiera to discuss how tax algorithms and artificial intelligence (AI) have become key tools for the tax authority.
1. How Does the SAT Use Technology and AI?
-
Massive cross-referencing of electronic invoicing data, tax returns, and third-party information.
-
Predictive algorithms that assign risk levels to each taxpayer.
-
Use of machine learning to identify atypical patterns in income and deductions.
2. Is AI Truly Effective as a Tax Tool?
-
Increased collection efficiency and reduced audit times.
-
Greater detection of inconsistencies without on-site visits.
-
Challenge: Avoiding false positives that result in unnecessary taxpayer burdens.
3. Risks for Compliant Companies
| Potential risk |
Impact |
| Automatic alerts due to minor errors |
Unexpected requirements |
| Large-scale deduction adjustments |
Temporary loss of liquidity |
| Mines for formal discrepancies |
Additional defense costs |
Even companies with robust accounting processes may be affected if they do not monitor the consistency of their information in real time.
4. Recommendations for the Business Sector
-
Automate reconciliation of CFDI against accounting records and tax returns.
-
Implement data quality controls before issuing (stamping) invoices.
-
Develop a digital tax risk map, prioritizing the indicators monitored by the SAT.
-
Train teams in analytics to respond quickly to electronic audits.
“The SAT’s artificial intelligence is only as good as the data it receives; companies must ensure their own information is impeccable,” - Belaunzarán emphasized
Conclusion
Electronic audits and artificial intelligence are now a reality in Mexico’s tax enforcement landscape. Adopting a proactive strategy for data governance and compliance is essential to minimize risks and benefit from an increasingly digital tax environment.
