Mexico: A Corporate/Commercial: Monterrey Overview

Monterrey's business environment is increasingly shaped by regulatory reforms, heightened enforcement and evolving stakeholder expectations. This overview outlines the key legal and regulatory developments affecting businesses across different factors and other strategic areas.

Stakeholders’ Engagement

Doing business in Mexico today requires a higher degree of multi-stakeholder engagement than in previous years. Regulatory developments are no longer limited to the enactment of new laws; they reflect a shift towards:

• stronger governance;
• increased interaction with authorities; and
• higher relevance of the interest and engagement of multiple stakeholders.

Therefore, companies are expected not only to comply with the legal framework, but also to understand the environment in which they operate and engage proactively with authorities and other key actors that influence the public policy and regulatory enforcement.

Against this backdrop, stakeholder engagement has evolved from a corporate best practice into a business essential. Developing a robust institutional strategy is no longer a concept reserved for multinational corporations or mature markets: it has a become a fundamental element of operating.

Approach to executive, legislative and judicial branches

Legislative initiatives, administrative policies and judicial precedents increasingly shape the regulatory environment in which companies operate. Maintaining strategic presence before authorities, at both federal and local levels, enables businesses to:

• understand policy priorities;
• participate in consultation processes where available; and
• anticipate the practical impact of legal and regulatory developments before they materialise into binding obligations.

In addition to seeking legal advice, it is important to have a 360-degree perspective on the business and broader environment.

Institutional liaison

Effective stakeholder engagement requires identifying the authorities, regulators, industry associations and other entities that influence the company’s operations. Understanding each stakeholder’s role, priorities and decision-making process enables companies to establish constructive relationships based on transparency, technical expertise and credibility. Maintaining this close relationship facilitates communication and strengthens the company's legal ground in its future decisions.

Regular engagement with public entities also allows companies to anticipate regulatory expectations, address compliance issues proactively and reduce the risk of disputes or enforcement actions, ultimately enhancing legal certainty and informed decision-making.

Rule of Law

Judicial challenges in the aftermath of the elected judges

The implementation of the judicial reform, which involves the election of judges and magistrados, has introduced a new institutional dynamic whose practical implementations are still unfolding. While the long-term impact remains uncertain, companies are increasingly focused on monitoring judicial consistency, predictability and the effectiveness of dispute resolution mechanisms, all of which are key factors in preserving legal certainty for commercial transactions and future investments.

At the local level, the implementation of state judicial reforms is expected to progress at different speeds, potentially resulting in varying standard, procedural practices and timelines across jurisdictions. Business operating nationwide should therefore align strategies considering the location of their different branches and the optimal spaces for future investments.

Limited protection of arbitrary administrative activity

In parallel, recent amendments to the Ley de Amparo (the law in Mexico protecting constitutional rights) have strengthened the power of administrative authorities in several areas, including measures related to the financial intelligence investigations and the temporary freezing of bank accounts. These developments underscore the growing importance of preventive compliance.

Legal role

The role of legal advisers has also evolved; corporate lawyers are no longer expected to provide purely reactive legal opinions or support during assessments or disputes. Instead, they are increasingly viewed as strategic business partners, assisting clients in identifying regulatory risks, engaging with stakeholders, structuring transactions and supporting decisions through the entire business cycle, and also by building strategic and sustainable relationships.

Tax Scrutiny

Increased social spending budget and tax audits

Tax audits are expected to remain a key focus for businesses in Monterrey. Beyond formal compliance, tax authorities are placing greater emphasis on the economic substance and business rationale of corporate structures and transactions. Maintaining robust documentation and a proactive compliance strategy will be essential to mitigate tax risks and facilitate any required corrective actions.

This is particularly relevant in restructurings, mergers, acquisitions, related-party transactions, financing and intra-group services. Tax analysis must accompany the transaction from the moment it is structured, rather than emerging only when the tax authorities question its effects.

New anti-money laundering regulations

Tax audits will continue to be relevant for companies. Added to this is the strengthening of the anti-money laundering regime through the 2025 amendments to the Federal Law for the Prevention and Identification of Transactions with Resources of Illicit Origin (Ley Federal para la Prevención e Identificación de Operaciones con Recursos de Procedencia Ilícita) and its implementing regulations in 2026.

The increased focus on the beneficial owner, the risk-based approach, internal controls and record-keeping all point towards a compliance framework that requires a deeper understanding of the client and the transaction rather than merely gathering the relevant documentation. This will be particularly relevant for sectors such as real estate and construction, foreign trade, and transactions involving complex corporate structures or cross-border flows.

Increased Administrative Enforcement

Regulatory scrutiny

Companies also face increased interaction with the state and municipal administrative authorities responsible for verifying operational and regulatory requirements in areas such as civil protection, environment, urban development, business operations, labour and health. The digitisation of procedures and oversight mechanisms is also enabling greater systematisation of information and enhanced monitoring capabilities from the authorities.

The challenge is that a single company may be simultaneously subject to different authorities, permits and obligations, and a compliance shortfall can result in fines, administrative proceedings, operational restrictions or business disruptions. Therefore, regulatory risk must be analysed by considering the operation.

Preventive compliance

A preventive approach assumes special importance and includes:

• mapping applicable authorities and obligations;
• identifying compliance gaps;
• keeping permits and documentation up to date; and
• establishing protocols for responding to inspections and requests.

Compliance thus ceases to be a purely reactive function and becomes a tool for risk management and business continuity.

Business Landscape

Monterrey's business environment is evolving rapidly, with regulatory and economic developments increasingly shaping business operations and investment decisions. Special attention is being paid to the following business areas.

• Labour: The gradual reduction of the workweek to 40 hours by 2030 will require businesses to reassess workforce planning, shift schedules and labour costs. Early planning will be key to ensuring compliance while maintaining operational efficiency.
• Import-export: Trade uncertainty and the evolving US–Mexico trade relationship are driving companies to reassess supply chains, customs compliance and sourcing strategies, with significant implications for manufacturing and investment decisions.
• Energy: Recent changes to Mexico's electricity framework require companies to reassess the regulatory requirements and viability of self-consumption projects under the new regime.
• Antitrust: Legislative developments to Mexico's competition regime require antitrust considerations to be addressed early in any transaction, particularly in M&A, where regulatory scrutiny extends beyond merger clearance.
• Water: Water regulation in Mexico is becoming increasingly restrictive. Recent reforms limit the transfer of water rights and introduce a new non-expiry guarantee fee regime, requiring companies to strengthen the management and compliance of their water concessions.
