The mandatory Electronic Declaration of Value (MVE) will be postponed once again. The Tax Administration Service (SAT) and the National Customs Agency of Mexico (ANAM) announced a further extension to the deadline for importers to comply with the mandatory electronic submission of this document. This decision represents the third extension granted by the authorities to one of the most important digitalization projects in foreign trade.
In a joint statement, both agencies announced that the requirement for the Electronic Mailing (MVE) will be extended until July 31, 2026 , to ensure that foreign trade users have the necessary tools to comply with this provision in a timely manner. This measure was established through the First Advance Version of the Second Resolution of Amendments to the General Rules of Foreign Trade for 2026, published on June 2nd on the SAT website.
The decision comes within the context of the digitalization strategy being promoted by the tax authority in coordination with ANAM, which seeks to migrate various foreign trade procedures to electronic platforms to strengthen information traceability, simplify processes, and improve customs control mechanisms. In the case of the MVE (Single Window for Foreign Trade), the scheme stipulates that information related to the customs value of goods be transmitted electronically through the “new” Single Window for Foreign Trade Procedures (VUTCE) before the goods are cleared.
According to the SAT (Mexican Tax Administration Service) and ANAM (National Association of Customs Agents), one of the main benefits of this mechanism is the mitigation of risks associated with errors in determining foreign trade duties. By submitting the information in advance and electronically, companies can reduce inconsistencies that could eventually lead to fines or penalties during customs audits.
In addition, the verifications carried out by the authorities are more efficient. The information submitted in advance allows for targeted inspections, reducing inspection times and, consequently, the time goods spend in customs. This is especially relevant for logistics operators and importing companies seeking to minimize costs associated with cargo release delays.
The economic component is also part of the arguments presented by the authorities. According to the statement, digitizing this process will reduce operating costs for both users and the agencies responsible for supervising and validating information related to import operations.
The Electronic Filing Mechanism (MVE) has been available for electronic submission since August 1, 2025; however, its mandatory implementation has faced several adjustments to the implementation schedule. With this new decision, the Tax Administration Service (SAT) and the National Association of Mexican Businesses (ANAM) are maintaining a gradual strategy for adopting the system, while continuing to support the business sector and implement technological adaptations to ensure compliance with the obligation.
With the announced expansion, the authorities reiterated their intention to facilitate compliance with foreign trade obligations through more agile, clear and accessible processes, while seeking to consolidate the digital transformation of customs procedures in Mexico.
