By Agustín L. Cerolini, Valentina Circolone and Tomás Mingrone

By means of Decree No. 353/2025 (hereinafter, the “Decree”), published in the Official Gazette on May 23, 2025, the National Executive Branch instructed the Tax Collection and Customs Control Agency (hereinafter, the “ARCA”, for its acronym in Spanish) to move forward with a process of simplification of tax reporting regimes, in line with the objectives of economic reactivation and formalization of the tax system.

I) Main provisions of Decree No. 353/2025.

The Decree sets forth the following general guidelines:

– Simplification of procedures for investment and asset acquisition, in coordination with the regulations to be issued by the Argentine Central Bank (the “BCRA” for its acronym in Spanish).

– Creation of the Open Finance System, allowing individuals and legal entities to securely share information with financial institutions registered with the BCRA, in order to facilitate access to credit and financial inclusion.

– Gradual and optional implementation of a simplified regime for income tax reporting by resident individuals and undivided estates, applicable exclusively to Argentine-source income.

– Strengthening of tax secrecy, establishing that the disclosure of tax information may only take place in accordance with the regulations issued by the BCRA and the ARCA, and with the express consent of the taxpayer.

– Comprehensive review of the regulations issued by the Financial Information Unit (“UIF” for its acronym in Spanish), with the aim of aligning them with the new provisions regarding anti-money laundering and counter-terrorism financing.

II) General Resolutions issued by ARCA.

In compliance with the provisions of the Decree, the ARCA issued the following resolutions, published on May 23, 2025:

– General Resolution No. 5696/2025: the ARCA provides that the obligated parties listed in Article 20 of Law No. 25,246 must refrain from requesting from their clients the income tax returns filed with the ARCA, in order to safeguard tax secrecy pursuant to Article 101 of Law No. 11,683.

– General Resolution No. 5699/2025: the ARCA updates the reporting regimes applicable to financial institutions, credit and debit card issuers, and Payment Service Providers (PSPs). The regulation modifies the minimum thresholds from which transactions carried out through bank accounts, cards, and virtual wallets must be reported.
