In recent years, the Servicio de Administraci\u00f3n Tributaria (SAT) has intensified enforcement related to so-called EFOS<\/strong> and EDOS<\/strong>.<\/p>\n

For many taxpayers, these concepts seem distant or technical\u2026 until they become a real problem.<\/p>\n

For that reason, it is essential to understand what they mean, the risks involved, and how to prevent or respond to this type of situation.<\/p>\n

 <\/p>\n

What are EFOS and EDOS?<\/h3>\n

In simple terms:<\/p>\n

    \n
  • EFOS<\/strong> are taxpayers that issue tax invoices (CFDI) without having the actual capacity to provide the services or deliver the goods being invoiced. In other words, they simulate transactions.<\/li>\n
  • EDOS<\/strong> are taxpayers that use those invoices to deduct expenses or claim tax credits, giving tax effect to transactions the authority considers nonexistent.<\/li>\n<\/ul>\n

     <\/p>\n

    Legal basis: Article 69-B of the CFF<\/h3>\n

    Article 69-B of the C\u00f3digo Fiscal de la Federaci\u00f3n establishes the procedure through which the authority may presume the nonexistence of transactions.<\/p>\n

    The process generally follows these stages:<\/p>\n

      \n
    1. The SAT detects irregularities.<\/li>\n
    2. The taxpayer is published on a preliminary list.<\/li>\n
    3. A period is granted to submit evidence and rebut the presumption.<\/li>\n
    4. If the taxpayer fails to prove the substance of the transactions, it is included on a final list as an EFOS.<\/li>\n<\/ol>\n

       <\/p>\n

      Subsequently, the authority identifies taxpayers who used those invoices: the EDOS.<\/p>\n

       <\/p>\n

      Relevant consequences<\/h3>\n

      Being involved in these schemes may lead to significant consequences:<\/p>\n

        \n
      • Non-deductibility of transactions<\/li>\n
      • Assessment of tax liabilities<\/li>\n
      • Fines<\/li>\n
      • Restriction or cancellation of digital stamp certificates<\/li>\n
      • Potential criminal liability in serious cases<\/li>\n<\/ul>\n

         <\/p>\n

        In practice, some of these measures may even paralyze a company\u2019s operations.<\/p>\n

         <\/p>\n

        Prevention is key<\/h3>\n

        It is essential to implement strong vendor review and control procedures.<\/p>\n

        This includes:<\/p>\n

          \n
        • Verifying tax status<\/li>\n
        • Confirming real operational capacity<\/li>\n
        • Validating delivery of goods or provision of services<\/li>\n
        • Retaining contracts, deliverables, and supporting evidence<\/li>\n
        • Preserving communications related to the transaction<\/li>\n<\/ul>\n

           <\/p>\n

          Proper document management can make all the difference during a tax review.<\/p>\n

           <\/p>\n

          If a procedure has already begun<\/h3>\n

          Immediate action is critical.<\/p>\n

          The rebuttal stage requires solid evidence proving that the transactions were real.<\/p>\n

          If an unfavorable resolution is issued, available legal remedies may include:<\/p>\n

            \n
          • Administrative revocation appeal<\/li>\n
          • Administrative litigation<\/li>\n
          • Amparo proceedings<\/li>\n<\/ul>\n

             <\/p>\n

            Through these remedies, both the substance and legality of the procedure may be challenged.<\/p>\n

             <\/p>\n
