Confaz Update Alters Tax Calculation Base and Affects Gasoline, Ethanol, Diesel, CNG, and Aviation Kerosene Starting in June

The National Finance Policy Council (Confaz) announced, on May 22, 2025, the review of the Average Price Weighted to Final Consumer (PMPF) of fuels. The measure was published in the Official Gazette of the Union the next day and will take effect on June 1. This update, which occurs periodically, serves as a mandatory reference for the tax calculation base of ICMS (Tax on Circulation of Goods and Services) in Brazilian states.

Understand How PMPF Directly Influences Pump Prices

The PMPF serves as a parameter for charging ICMS on various fuels such as regular gasoline, hydrated ethanol, diesel oil, compressed natural gas (CNG), and aviation kerosene. Although the adjustment does not determine immediate increases to consumers by itself, it may indirectly affect the prices charged at the pumps. This happens because the state tax value is based on this disclosed average price. Thus, any change in PMPF tends to influence market behavior.

Update Was Made Based on State Price Variations

According to Confaz, the review aims to more accurately reflect the average prices practiced in the states. Ethanol was the only fuel whose values for all states were updated and disclosed in full. This action ensures greater alignment between the reality of regional prices and tax collection. The procedure, therefore, is essential to ensure that the calculation base for ICMS is fair and updated frequently in line with market dynamics.

New Average Weighted Price Does Not Automatically Change the Consumer Price, but Impacts Transfers

Although the new PMPF is used to determine the value on which ICMS is applied, the change does not automatically imply an increase or decrease in the final price to the consumer. However, it may influence distributors and gas stations, which could result in adjustments to the prices charged. States with a high reliance on ICMS revenue from fuels tend to be the most sensitive to these changes. Therefore, revisions have a strong fiscal impact, even if the reflection for consumers takes a few days to appear.

PMPF Update Reinforces Fiscal Transparency and Contributes to Balance in State Revenue

Confaz performs the PMPF update as part of a regular routine. The purpose is to maintain coherence between the behavior of the fuel market and the calculation base used by the states. This practice aids transparency in the tax process and helps federal entities better plan their revenue. The publication of updated values is a legal requirement and is part of the fiscal management policy that seeks balance between revenue and economic reality.

Engineers want to carve through Africa with a giant canal to bring water from the world’s second-largest river to a dying lake on the edge of the Sahara Desert that has already lost 90% of its water.

Workers were opening a modern road in Dover when they found, 6 meters below the asphalt, a 3,500-year-old boat made of stitched oak and plant fibers.

A giant brown band visible from space, approximately 8,850 kilometers long, connected Africa to America in the Atlantic Ocean, and satellites revealed that it is neither land nor pollution, but the largest accumulation of seaweed in the world, which broke records in 2025.

In just one cast, fishermen are surprised to capture 14,096 mullets in Bombinhas and close a historic season with 58,000 fish; scene recorded in the Santa Catarina paradise marks the last day of the 2026 season.

Two 17-year-old Kenyans use coconut shells, corn cobs, and recycled materials to create an exhaust filter that reduces 93.3% of pollutant particles and wins an environmental award in Africa.

Consumers eat six times more chicken than in the 1960s, global meat supply quadruples in 60 years, and FAO report reveals the invisible cost on the plate: livestock could drive 80% of the increase in agricultural emissions over the next decade.

Motorcyclist sees excavator arriving at the edge of a river in Bosnia, calls neighbors in minutes and turns a hydroelectric project into a resistance lasting more than 10 years with five expired concessions.

Nissan sells outside Brazil a 1.0 turbo sedan with CVT transmission and autonomous braking that many domestic cars do not yet offer: Almera combines up to 100 hp, ADAS package, collision alert, and fuel consumption of up to 23.3 km/l in some Asian markets.

Public works in a Brazilian city opened the ground of a busy avenue and revealed the bow of a 22-meter 19th-century ship, buried where rivers, streams, and vessels once passed.

Flying rivers that release more than 70% of the rain in areas of Peru and Bolivia depend on public forests without a destination in the Amazon, but the advance of deforestation puts this vital corridor at risk.

Workers were opening a new tunnel at Estação da Luz when they found more than 6,000 century-old artifacts buried two meters below the street, revealing that one of the busiest areas of São Paulo still holds forgotten layers underground.
