Decree signed on Wednesday, September 9, 2026, reduces R$ 0.63 per liter in PIS/Pasep and Cofins on gasoline, zeros out contributions on hydrated ethanol, and creates an initial R$ 1 subsidy per liter for diesel. The measure replaces the current R$ 0.44 set by MP 1.358/2026, according to the Planalto.
The Federal Government announced on Wednesday, September 9, 2026, the signing of a decree that reduces the PIS/Pasep and Cofins rates by R$ 0.63 per liter of gasoline and zeros out contributions on hydrated ethanol. For diesel, a subsidy of R$ 1.00 per liter is set for “the first period,” an amount that may be adjusted, suspended, or extended by the Ministry of Finance depending on market conditions.
The information was published by ND Mais on September 9, 2026, from a text by Larissa Ferreira, edited by Renato Becker, based on a statement from the Secretariat of Social Communication of the Palácio do Planalto.
R$ 0.63 Less Per Liter in Federal Taxes on Gasoline
-
The government was preparing to end a subsidy that costs R$ 1.2 billion per month and accounts for almost 17% of the price of gasoline at refineries, but the war changes the plans, postpones the removal of the benefit, and reignites the alert about a new rise in fuel prices in Brazil.

Drivers are falling for these scams without realizing: operation reveals closed gas stations, adulterated fuel, and hidden losses when refueling.
-
New Fiat EV, priced at R$ 77,000, will bring a reinterpretation of the 147 and a consumption equivalent to 70 km/l.

Petrobras surprises the market by cutting diesel by R$ 0.35 per liter, and the decision may ease the tax impact for drivers and transport companies.
The government’s stated goal is to mitigate the rising prices of international oil and fuels.
Hydrated Ethanol Tax Contributes Zeroed Out
In addition to the gasoline cut, the decree zeros out the PIS/Pasep and Cofins contributions on hydrated ethanol.
This measure affects the fuel sold directly at the pumps for flex-fuel vehicles.
Diesel Receives R$ 1 Per Liter “In the First Period”
For diesel, the government established a subsidy of R$ 1.00 per liter “in the first period.”
The subsidy is a financial support, not a tax cut, unlike the arrangements made for gasoline and ethanol.
Ministry of Finance Can Modify, Suspend, or Extend the Subsidy
The R$ 1 per liter diesel subsidy can be modified, suspended, or extended by an act from the Ministry of Finance, depending on market conditions.
The rule makes the subsidy conditional on international price trends.
The rate is the percentage used to calculate how much one pays in a specific tax, explains ND Mais.
PIS/Cofins are social contributions whose collection is allocated for specific purposes, applying to revenues as well as imports of goods and services.
Decree replaces the R$ 0.44 from MP 1.358/2026
In a statement, the Secretariat for Social Communication of the Palácio do Planalto stated that the reduction of tax rates for gasoline replaces and expands the economic support outlined in Provisional Measure 1.358/2026.
The MP set a rate of R$ 0.44 per liter and was in effect until the announcement day. The new cut of R$ 0.63 is R$ 0.19 higher per liter.
MP authorizes financial support for producers and importers
MP 1.358/2026 allows the government to grant economic subsidies, that is, financial support, to producers and importers of petroleum-derived fuels.
This instrument supports the R$ 1 subsidy per liter announced for diesel.
Durigan, Moretti, and Silveira detail the measures at 5:30 PM
Ministers Dario Durigan (Finance), Bruno Moretti (Planning), and Alexandre Silveira (Mines and Energy) were scheduled to detail the measures in a press conference at 5:30 PM this Wednesday.
The press conference was scheduled for the same day the decree was signed.
Package announced on September 9 replaces the current MP
On September 9, 2026, the package for gasoline, ethanol, and diesel was announced as a response to the international rise in oil prices, replacing the R$ 0.44 support per liter from MP 1.358/2026.
The R$ 0.63 cut on gasoline and the elimination of ethanol taxes come by decree, while the R$ 1 subsidy for diesel is subject to review by the Finance Ministry.
