**TL;DR:** IEPS 2026: a fixed per-liter quota cushioned by weekly stimulus decrees that can vanish; unlike VAT it is not creditable — it is cost.

- The quota is inflation-adjusted every January via the DOF.
- The weekly SHCP stimulus is not permanent; budget scenarios.
- IEPS is cost; only VAT itemized on the CFDI is creditable.
- Without a CFDI you lose the full cost deduction, IEPS included.

## Summary

Mexico's IEPS on motor fuels is a fixed per-liter quota, inflation-adjusted yearly and cushioned by weekly SHCP stimulus decrees in the DOF that can vanish any week. Unlike VAT it is not creditable — it is cost. The CFO's levers: automatic CFDI on every fill-up, fuel-efficiency programs and budgeting under full, partial and zero stimulus scenarios.

## Frequently asked questions

### Can a company credit the IEPS on its fleet fuel?

As a rule, no: for a business consuming the fuel in its operations, IEPS is part of the per-liter cost, not a recoverable tax.

### Where do I track the weekly IEPS stimulus?

In the SHCP's weekly decree published in the Official Gazette (DOF), listing the stimulus percentage per fuel type.
