Overview
- For taxable events from January 1–31, 2026, Decree 929/2025 applies partial updates to the Liquid Fuels Tax (ICL) and the Carbon Dioxide Tax (IDC) and shifts the remaining adjustments to February 1.
- January’s per‑liter changes are set at ARS 17.291 (ICL) and ARS 1.059 (IDC) for gasoline, and ARS 14.390 (ICL) and ARS 1.640 (IDC) for diesel, with an additional ARS 7.792 differential for designated regions.
- The measure, published in the Boletín Oficial and signed by President Javier Milei, Economy Minister Luis Caputo, and Cabinet Chief Manuel Adorni, modifies the earlier framework in Decree 617/2025.
- The decree maintains the longstanding diesel tax differential for Patagonia, the Buenos Aires district of Patagones, and Mendoza’s Malargüe to account for logistical and climatic costs.
- The updated amounts stem from Law 23.966’s CPI‑indexed formula and cover postponed updates from 2024 and the first three quarters of 2025, with reporters noting likely pump price increases depending on industry pass‑through.
