Brazil Implements 2026 Fuel ICMS Hike With Gasoline at R$1.57 and Diesel at R$1.17

Overview

• The new ICMS amounts took effect on January 1, raising gasoline by R$0.10 to R$1.57 per liter and diesel by R$0.05 to R$1.17 per liter.
• Reports diverge on the GLP figure, with some outlets citing R$1.05 per cylinder and another citing R$1.47 per kilogram, a discrepancy traceable only to the official Confaz convênios.
• Confaz formalized the updated nominal values in convênios published in the Diário Oficial da União on September 8, 2025.
• Comsefaz says the adjustment followed Law Complementar 192/2022 and applied ANP average monthly prices from February to August 2025 compared with the same months in 2024.
• This is the second consecutive year of higher fuel ICMS, a type of increase that economists note tends to pass through to broader consumer prices.
