Overview
- For the week of Nov. 14–20, 2026 the Secretaría de Hacienda set final IEPS quotas so Magna faces a 6.6816 pesos per liter charge with a tiny 0.28% stimulus and Premium pays the full 5.6579 pesos per liter.
- Diésel remains exempt with a 100% general stimulus plus a small complementary support that keeps its final IEPS at 0.00 pesos for a tenth consecutive week.
- The Premium quota has reached the annual maximum allowed for 2026 and the Magna level sits only cents below its yearly cap, limiting how much IEPS can rise further this year.
- These weekly adjustments are meant to smooth the pass-through of international price moves to pump prices, so drivers and freight operators should expect higher tax components at stations this period.
- Hacienda published separate tabulators for northern and southern border municipalities, so the exact stimulus and final IEPS can vary by location and drivers should check the local table before filling up.
