Introduction to the 2025 Economic Package and its Implications

The 2025 Economic Package, delivered to the Chamber of Deputies on Monday, proposes expanding the oversight powers of financial institutions beyond traditional banks, including fintech companies. This move allows regulatory authorities to review accounts and deposits in these entities, acknowledging the growing diversification of Mexico’s financial system.

Background on the Proposed Reform to the Federal Fiscal Code (CFF)

The proposed reform to the Federal Fiscal Code (CFF) for 2026 aims to adjust the reference from “bank account statements” to the broader term “financial institution account statements.” This change seeks to close loopholes in an environment where fintech companies and other non-bank intermediaries have gained significant weight in providing digital financial services.

Alignment with the Fintech Regulatory Framework

The legislative proposal aims to align fiscal regulations with the regulatory framework established in 2018, which recognizes Financial Technology Institutions (Fintech Law). Specifically, it highlights that electronic payment fund accounts have their own CLABE and are part of Mexico’s financial system, thus deserving the same treatment as a bank account.

Government’s Objective

By expanding the available information for verifying the true taxpaying capacity of digital financial service users, the government aims to strengthen the constitutional principle of proportional taxation.

Who is Affected and Why is it Relevant?

The proposed changes in the 2026 Tax Miscellanea primarily affect fintech companies and other non-bank financial intermediaries. These entities have experienced rapid growth in recent years, offering innovative digital financial services such as mobile payments, peer-to-peer lending, and robo-advisory. As their market share expands, so does the need for proper regulatory oversight to ensure fair competition and protect consumers.

Key Players

Some prominent fintech companies in Mexico include:

  • Konfio: A small business lending platform that uses alternative data to assess creditworthiness.
  • Celmatix: A fertility tech company that provides genetic testing and data-driven insights to improve in vitro fertilization success rates.
  • TransferWise (now Wise): A cross-border money transfer service that offers lower fees and real exchange rates compared to traditional banks.

Impact on the Financial Ecosystem

The expansion of oversight to fintech companies will have several implications for Mexico’s financial ecosystem:

  • Increased Transparency: Regulators will have better access to information, enabling them to monitor and enforce tax compliance more effectively.
  • Level Playing Field: By applying the same standards to fintech companies as traditional banks, the government promotes fair competition and prevents unfair advantages.
  • Consumer Protection: Enhanced oversight can lead to better consumer safeguards and reduced risks associated with digital financial services.
