Por FactBox Admin
The Ministry of Finance determined the variable components of the specific tax on fuels established in Law No. 18,502, through Exempt Decree No. 261, signed in Santiago on September 8, 2026. The resolution was published in the Official Gazette of the Republic of Chile No. 44,546, on Wednesday, September 9, 2026, and its values are effective as of September 10.
The decision, adopted by order of the President of the Republic and signed by the Minister of Finance, Jorge Antonio Quiroz Castro, is part of the Fuel Price Stabilization Mechanism created by Law No. 20,765 and its regulation approved by Supreme Decree No. 1,119 of 2014. The variable component is added to or subtracted from the base component to form the final tax rate, as provided for in Article 3 of Law No. 20,765 and Article 8 of its regulation.
Determined variable components
For the week beginning Thursday, September 10, 2026, the Ministry of Finance set the following variable components (in UTM/m³):
- 93-octane Automotive Gasoline: -1.9440
- 97-octane Automotive Gasoline: -2.3687
- Diesel Fuel: -3.0176
- Vehicular Liquefied Petroleum Gas: 0.0000
- Vehicular Compressed Natural Gas (in UTM/1000m³): 0.0000
Resulting tax rates
As a result of the application of these components, the resulting specific tax rates are as follows:
- 93-octane Automotive Gasoline: base component 6.0000, variable -1.9440, resulting tax 4.0560 UTM/m³
- 97-octane Automotive Gasoline: base 6.0000, variable -2.3687, resulting tax 3.6313 UTM/m³
- Diesel Fuel: base 1.5000, variable -3.0176, resulting tax -1.5176 UTM/m³
- Vehicular Liquefied Petroleum Gas: base 1.4000, variable 0.0000, resulting tax 1.4000 UTM/m³
- Vehicular Compressed Natural Gas: base 1.9300, variable 0.0000, resulting tax 1.9300 UTM/1000m³
Regulatory basis and publication
The decree is issued by virtue of Article 32 No. 6 of the Political Constitution of the Republic, DFL No. 7,912 of 1927, and Laws No. 20,765 and No. 20,794, which create and extend the stabilization mechanism. The estimates are based on ordinary letters No. 857 and No. 858, both dated September 8, 2026, from the National Energy Commission, and Resolution No. 36 of 2024 from the Comptroller General of the Republic.
Paragraph 4 of the decree orders the publication of the resolution on the institutional website of the Ministry of Finance through a technical report, in accordance with Article 5 of Law No. 20,765.
The update of the variable component directly affects the final price of gasoline and diesel paid by drivers, by adjusting the tax burden transferred to the pump. With negative values for gasoline and diesel, the measure tends to moderate the impact of the tax on motorists’ pockets during the week beginning September 10.
