Overview

• ARCA enabled a new Nuestra Parte section that lets identified taxpayers privately view U.S. FATCA data tied to their accounts for the 2023 period.
• Following the launch, an interface error briefly displayed the files within user sessions; the agency withdrew the material and said no fiscal secrecy was violated.
• The accessible records currently show the reporting U.S. financial institution and account number, with FATCA coverage linked to accounts paying over US$10 in interest.
• Officials signaled that discrepancies could prompt information requests, inspections, or voluntary regularization by those with undeclared assets.
• In parallel from October 2025, banks and digital wallets must monitor large movements, with thresholds such as ARS 50,000,000 for individual transfers and ARS 10,000,000 for cash withdrawals, and may retain funds until documentation is provided.
