Update on Excise Tax incentives applicable to fuels

24 March 2026

On 20 March 2026, the Ministry of Finance and Public Credit (SHCP) announced, in the evening edition of the Official Gazette of the Federation, the new agreement on tax incentives regarding the Special Tax on Production and Services (Excise Tax) applicable to petrol and diesel, valid from 21 to 27 March 2026.

This is the first time, since April 2025, that Magna petrol has received significant support; meanwhile, for Premium petrol, this is the first incentive published since October 2023.

The reactivation of the incentive takes place in a context of volatility in international fuel prices, which is why the tax authority adjusts Excise Tax rates in accordance with the mechanism established in the applicable regulations.

Below is a summary of the percentages and rates in force for this week:

Fuel	Incentive percentage	Amount of tax incentive (Mexican pesos/litre)	Rate (mexican Pesos/litre)
Petrol under 91 octane (Magna)	24.08%	$1.6133	$5.0868
Petrol 91 octane or higher and nonfossil fuels (Premium)	7.47%	$0.4224	$5.2355
Diesel	61.80%	$4.5505	$2.8129

It is important to highlight that the percentages and rates indicated are not homogeneous at the national level, as the border regions are subject to specific decrees, which were published on 20 March 2026 in the evening edition of the Official Gazette of the Federation.

We recommend that taxpayers assess the impact of these incentives on the determination of their costs and on the planning of their operations, particularly in sectors with intensive fuel consumption.
