Overview
- Decree 617/2025 was published in the Boletín Oficial, setting a new update scheme for liquid fuel and CO₂ taxes starting in September.
- Partial increases will apply from September 1 to 30, with the full accumulated adjustment taking effect on October 1, 2025.
- For gasoline, the decree sets increases of $10.523 per liter for the fuel tax and $0.645 per liter for the CO₂ tax.
- For diesel, it establishes $8.577 per liter for the general tax, $2.895 per liter for the differential rate, and $0.978 per liter for the CO₂ tax.
- The rule repeals Decree 466/2024 and aligns updates with the statutory quarterly CPI-linked mechanism, with analysts expecting pass-through to pump prices and knock-on effects on transport and consumption.
