Equipo de Redacción

Annex 24 and Annex 30 are key documents for companies operating under the IMMEX program, as they help maintain control over inventories and tax credits related to temporary imports.
Reconciling these annexes is essential to avoid operational issues, fiscal risks, and penalties.

In this article, we explore how proper validation of these annexes can ensure efficient IMMEX administration and protect your VAT and IEPS certification.

Why Is the Reconciliation of Annex 24 and Annex 30 Essential for IMMEX Companies?

Reconciling Annex 24 and Annex 30 is a crucial activity for companies participating in the IMMEX program.
This process ensures that the information in both annexes matches the records from the SAT (Servicio de Administración Tributaria), preventing discrepancies that may lead to penalties or audits.

Additionally, accurate reconciliation supports informed decision-making and improves inventory administration, directly impacting efficiency in foreign trade processes.

How Does the Lack of Reconciliation Affect Annex 24 and Annex 30?

If Annex 24 and Annex 30 are not reconciled properly, companies may face several issues:

  • Fiscal penalties: The SAT may impose fines and surcharges if inconsistencies are found in temporary import records and tax credits.
  • Loss of VAT and IEPS certification: Misaligned information can jeopardize a company’s IMMEX certification.
  • Delays in customs processes: Poor reconciliation may cause operational setbacks that affect the supply chain.

3 Benefits of Reconciling Annex 24 and Annex 30

Performing a monthly reconciliation of Annexes 24 and 30 offers multiple operational and fiscal advantages. Here are some of the most important:

  • Avoid SAT penalties and audits:
    Monitoring discrepancies monthly allows you to detect errors before they escalate, reducing the risk of fines or audits from the SAT.
  • Protect your VAT and IEPS certification:
    Proper reconciliation ensures your company meets IMMEX requirements, helping you maintain your VAT and IEPS certification.
    This not only protects you fiscally but also optimizes your customs operations.
  • Improve efficiency in IMMEX program administration:
    A consistent and accurate reconciliation enhances the management of temporary imports, ensuring inventory control complies with fiscal regulations.

How Is the Reconciliation of Annex 24 and Annex 30 Performed?

Reconciling these annexes involves comparing inventory data (Annex 24) with tax records (Annex 30).
This typically includes reviewing each temporary import, ensuring tax credits are applied correctly, and checking that the data aligns with the information submitted to the SAT.

It is recommended to complete this process monthly to detect inconsistencies early and perform the necessary adjustments before they become serious issues.
