The evolution of the tax regime applicable to maquiladora companies in Mexico has reached a critical stage in 2026. The conclusion of various advance pricing agreements, coupled with the update of audit guidelines, has heightened the need for rigorous transfer pricing management. In this context, it is essential to mitigate the risks of double taxation and ensure that a permanent establishment is not established.
In a global environment characterized by greater demands for transparency and economic substance from tax authorities, compliance with transfer pricing regulations has ceased to be a purely administrative obligation and has become a key element of operational continuity.
Regulatory Transition: From Unilateral APAs to Safe Harbor and BAPAs
The current regulatory framework in Mexico has altered the compliance options available to maquiladora companies:
- End of Unilateral APAs. With the expiration of agreements covering the 2020–2024 period, the possibility of automatic renewal under unilateral schemes is eliminated.
- Return to the Safe Harbor. This mechanism is established as one of the main compliance alternatives under the Income Tax Law (LISR), requiring an accurate calculation of taxable income to avoid the creation of a permanent establishment.
- Adoption of bilateral agreements (BAPAs). The use of agreements between tax authorities of different jurisdictions—primarily between Mexico and the United States—is encouraged under the Qualified Maquiladora Approach (QMA).
Relevance of the new schemes in the maquiladora sector
The strengthening of tax enforcement in this area responds to various structural factors within the industry:
- Jurisdictional protection. The proper application of Transfer Pricing methods is an essential mechanism to prevent a foreign-resident entity from being considered to have a tax presence in Mexico.
- Long-term legal certainty. While BAPA agreements involve greater complexity in negotiation, they provide tax stability over several fiscal years, reducing uncertainty in financial planning.
- Complexity in valuation. The implementation of updated methodologies, such as version 3.0 of the QMA, requires a detailed analysis of assets, functions, and risks to support the profitability reported to the tax authority.
Practical implications for multinational groups
Maquiladoras operating under the IMMEX program face challenges that require proactive management:
- Emphasis on prevention. Supporting documentation must align with OECD guidelines and the specific criteria established in current local regulations for 2026.
- Evaluation of methodologies. Comparative analyses must be conducted between the use of the Safe Harbor and the adoption of APA agreements, considering costs, resolution times, and effects on the tax burden.
- Cross-border coordination. Alignment between the maquiladora in Mexico and its related parties abroad is essential to ensure an appropriate allocation of profits across jurisdictions.
Conclusions: A preventive and strategic approach
The tax context applicable to maquiladoras in Mexico in 2026 requires the adoption of a preventive and strategic approach to Transfer Pricing. The elimination of unilateral APAs and the strengthening of mechanisms such as the Safe Harbor and bilateral agreements (BAPAs) compel taxpayers to rethink their compliance policies with a comprehensive and long-term vision.
In this scenario, prevention emerges as a key element for mitigating tax risks, avoiding contingencies arising from adjustments by the tax authority, and reducing the likelihood of double taxation. Likewise, strategic planning allows for the early evaluation of available alternatives, optimizing the tax burden and ensuring alignment with international standards.
Finally, proper Transfer Pricing management not only contributes to regulatory compliance but also strengthens the operational sustainability of multinational groups by providing legal certainty and stability in their cross-border operations
