Tax incentives for gasoline and diesel for September are set to zero

The Ministry of Finance and Public Credit announced the fiscal stimulus percentages applicable to gasoline under 91 octane and diesel for the fishing and agricultural sectors during September 2026, which are set at 0% for the three fuels. The measure is published in the Official Gazette of the Federation on Wednesday, August 19, 2026, through Agreement 127/2026, and will enter into force on the day of its publication.

The agreement, signed by proxy by the Undersecretary of Revenue, Carlos Gabriel Lerma Cotera, is based on the Energy Law for the Countryside, the Decree on fiscal stimuli regarding the special tax on production and services (IEPS) applicable to fuels published on December 27, 2016, and the Agreement establishing fiscal stimuli for gasoline and diesel in the fishing and agricultural sectors of December 30, 2015.

Percentages set for September 2026

Article Two of the agreement establishes the stimulus percentages applicable throughout the national territory for the month of September 2026:

• Gasoline under 91 octane: 0.00%
• Diesel for the fishing sector: 0.00%
• Diesel for the agricultural sector: 0.00%

How the stimulus is applied

According to Article Three, the percentages are applied to the reduced rates corresponding to gasoline under 91 octane and diesel. The result is added to the corresponding value-added tax, and the total amount is the quantity applied to reduce fuel prices at the time they are sold to the beneficiaries of both sectors.

The reduced rates are those published in the Official Gazette of the Federation through the agreements that announce the percentages, the fiscal stimulus amounts, and the reduced IEPS rates applicable to fuels for the period specified in said agreements.

Regulatory framework and validity

The agreement is issued based on article 31, fraction XXXIV of the Organic Law of the Federal Public Administration, article 5, second paragraph of the Energy Law for the Countryside, and article 3 of the Internal Regulations of the Ministry of Finance and Public Credit. The Sole Transitory Article provides that the agreement enters into force on the day of its publication in the Official Gazette of the Federation.

Setting the stimuli at zero implies that, during September 2026, producers in the fishing and agricultural sectors will not have an additional reduction in the price of the gasoline and diesel they consume, which directly affects the production costs of both sectors across the country.
