Mandatory for entities that produce, import, or sell covered fossil fuels in taxable events defined by LIEPS.
Exceptions depend on statutory exclusions, product definitions, and whether fuels are destined for covered combustion uses, as interpreted under LIEPS provisions and guidance.

What’s Required
Obligated taxpayers must:
Determine taxable events: the tax applies to the sale and importation of covered fossil fuels under LIEPS provisions governing excise taxes.
Apply the relevant carbon quota/rate: rates are differentiated by fuel type and are linked to carbon content (LIEPS schedules and annual updates can apply).
Maintain tax records and invoices: demonstrate volumes, fuel classification, import documentation, and tax calculation support.
Manage exemptions or special cases: the carbon tax design has historically included exclusions for certain fuels (for example, treatment of natural gas has been discussed in technical analyses), and taxpayers must apply the law as written and updated.
Important Deadlines
Legislative reform package published: 11 December 2013 (DOF) is a key reference point for the reform, introducing environmental taxes, with application from 2014 in practice, as reflected in authoritative technical summaries.
Ongoing updates: rates and quotas can be updated; compliance is continuous with periodic tax filings per fiscal obligations.
Current Status
In force as part of the LIEPS framework, with published consolidated texts available via official sources.
Penalties for Non-Compliance
Tax non-compliance can trigger fiscal penalties, surcharges, audits, and enforcement actions under Mexico’s tax administration powers.
Misclassification of fuels, under-declaration of volumes, or incorrect rate application are core audit risks.
Examples of Known Violations
Common failure modes include:
incorrect tariff application due to fuel misclassification,
discrepancies between customs/import records and declared taxable volumes,
inadequate documentation supporting exemptions or special treatments,
weak controls where fuel blending changes carbon content assumptions.
