Understanding the “Materialidad de las Operaciones” in Mexico

In recent years, the Servicio de Administración Tributaria (SAT) in Mexico has intensified its scrutiny of business transactions, placing special emphasis on the concept of Materialidad de las Operaciones (Materiality of Operations). This principle is crucial for companies and individuals conducting business in Mexico, as failing to provide sufficient proof of the legitimacy of transactions can lead to severe tax consequences.

What is “Materialidad de las Operaciones”?

Materialidad de las Operaciones refers to the obligation of businesses to demonstrate that their transactions are real, justified, and supported by proper documentation. In other words, it is not enough to issue an invoice (CFDI); companies must prove that the services or goods were actually provided and that they contribute to their economic activity.

Key Aspects of Materiality

To comply with SAT requirements, businesses should consider the following elements:

1. Contracts and Agreements – A well-drafted service or supply contract helps substantiate the legitimacy of transactions.

2. Physical and Digital Evidence – Documentation such as emails, reports, invoices, delivery receipts, and photographs can serve as supporting proof.

3. Operational and Economic Justification – The transaction should align with the company’s regular business activities and financial structure.

4. Employee and Resource Allocation – Proof that personnel and resources were dedicated to fulfilling the transaction.

5. Third-Party Verification – If applicable, having independent third parties verify the transaction’s execution can strengthen its materiality.

Why is Materiality Important?

Failure to prove materiality can result in:

– Rejection of tax deductions by SAT
– Requalification of transactions as simulated or fraudulent
– Heavy fines and tax liabilities
– Administrative responsibility
