Mexico’s Transfer Pricing Crackdown: What CPAs Should Know About Rising Audit Risk

Multinational companies operating in Mexico are facing heightened scrutiny from the Mexican Tax Administration Service (SAT). With a renewed focus on Transfer Pricing enforcement, SAT is ramping up efforts to prevent profit shifting and ensure proper tax compliance—especially among businesses with cross-border operations.

For CPA firms and advisors supporting multinational clients, this signals an urgent need to revisit Transfer Pricing strategies and documentation before audits become an expensive reality. 

Transfer Pricing Enforcement Drives Revenue Gains

Between 2019 and 2024, SAT collected over 106 billion pesos (approximately $6.2 billion USD) from Transfer Pricing audits—a staggering 367% increase compared to the previous six-year period. In 2023 alone, audit corrections surpassed 19 billion pesos, with targeted sectors including automotive, mining, electronics, and telecommunications.

These results highlight not only the effectiveness of SAT’s specialized audit approach, but also the growing risks for multinational corporations that fail to stay compliant.

Why It Matters for Cross-Border Business

Transfer Pricing rules are designed to ensure that transactions between related entities are conducted at arm’s length, based on fair market value. When these rules are ignored or improperly documented, it can lead to significant underpayment of taxes in higher-tax jurisdictions like Mexico—something SAT is actively working to prevent.

To support this effort, SAT has established a dedicated Transfer Pricing department, tasked with identifying inconsistencies and enforcing compliance across sectors. Given Mexico’s strategic position and close economic ties to the U.S., companies doing business in the region must take this increased enforcement seriously—especially as SAT continues to build expertise and expand its audit capabilities.

Compliance is More Important Than Ever

Mexican tax regulations require taxpayers to maintain up-to-date Transfer Pricing documentation in order to claim certain deductions. Without proper documentation, businesses may face significant penalties, disallowed deductions, and reputational damage during audit proceedings.

In today’s environment, compliance isn’t just a matter of regulatory box-checking—it’s a strategic imperative. CPA firms advising multinational clients should take proactive steps to review existing policies, validate intercompany pricing, and ensure documentation is defensible under audit.
