Mexico's Finance Ministry widens gasoline tax relief for Oct. 10–16; diesel remains tax-free
The per-liter IEPS tax falls to 2.39 pesos for regular and 1.62 for premium; diesel keeps a 100% credit.
Mexico's Finance Ministry (SHCP) has increased the fiscal credit on the special production and services tax (IEPS) charged on gasoline for the week of Saturday, October 10, to Friday, October 16, 2026. Diesel keeps its full credit, so no IEPS is charged on it. The measure is set out in Agreement 152/2026, published in the Official Gazette (DOF) on October 9.
IEPS per liter this week
According to the official document:
- Regular gasoline (Magna, under 91 octane): the credit covers 64.31% of the tax, or 4.3091 pesos per liter. The tax actually charged is 2.3910 pesos per liter.
- Premium gasoline (91 octane or higher): the credit rises to 71.29%, or 4.0333 pesos per liter. The tax charged is 1.6246 pesos per liter.
- Diesel: the credit is 100% (7.3634 pesos per liter), so the tax is zero.
Compared with last week
Under the previous agreement (148/2026), in effect October 3–9, regular gasoline was taxed 2.4563 pesos and premium 2.0828 pesos per liter. With the new agreement:
- Regular pays about 6.5 centavos less in IEPS per liter.
- Premium pays about 46 centavos less per liter, the biggest change this week.
- Diesel remains tax-free, as it was the previous week.
For scale: adding the credit and the tax charged, the full IEPS would be roughly 6.70 pesos per liter of regular, 5.66 for premium and 7.36 for diesel. The government gives up most of that revenue.
What it means at the pump in Cancún
The credit lowers the tax; it does not set the pump price. Retail fuel prices in Mexico are deregulated: each station sets its own price based on supply costs, logistics and margin. A bigger credit therefore does not guarantee a cheaper liter at your local station. What it does is ease upward pressure when international oil benchmarks rise.
If you drive daily in Cancún, whether for ride-hailing, tourist transport or deliveries, premium gets the most tax relief this week. For freight and diesel vehicles, a zero tax matters most, since that cost also feeds into shipping goods to the peninsula.
What you can do
- Compare before filling up. Mexico's consumer protection agency (Profeco) publishes a weekly "Quién es Quién" fuel price report at gob.mx/profeco, listing prices by station.
- Ask for a receipt and check that the pump starts at zero.
- If you are shorted on liters or the price doesn't match what's posted, you can file a complaint with Profeco through its official channels.
The Finance Ministry issues these agreements weekly, usually on Fridays, covering Saturday through Friday. The next one is expected around October 16 and will set the credit starting October 17.
