In the current Mexican legal landscape, tax and customs enforcement has taken on an increasingly punitive tone—especially following the December 2024 constitutional reforms, which expanded the classification of serious tax crimes, enabled automatic pre-trial detention, and limited procedural benefits for taxpayers and companies.
In this context, a troubling trend has emerged: some administrative authorities show resistance or outright refusal to recognize and apply human rights principles in tax and customs matters, as if these areas were exempt from constitutional guarantees.
This article analyzes the current tax enforcement paradigm, the implications of judicial reform, and the irreplaceable role of human rights as a limit and counterbalance to the exercise of tax authority.
In recent years, Mexico’s tax strategy has shifted toward intensive enforcement, particularly in sectors linked to foreign trade. A combination of electronic audits, deep inspections, and a “tax evasion combat” narrative has created a climate of continuous pressure.
In many cases, enforcement actions are carried out without regard for due process, the presumption of innocence, or proportionality in sanctions. The increasing use of precautionary measures—such as asset freezes, certificate cancellations, or blocked bank accounts without a final ruling—demonstrates a logic that prioritizes revenue collection and suspicion over individual rights and guarantees.
Since the 2011 constitutional reform on human rights, Mexico adopted a legal model that places human dignity and the principles of pro persona and consistent interpretation at the center of its legal framework. This paradigm obligates all authorities, within their competencies, to promote, respect, protect, and guarantee human rights—including administrative bodies like SAT and ANAM.
The Mexican Supreme Court has consistently reaffirmed that human rights apply equally in tax matters, even in the context of audits, tax assessments, precautionary seizures, or customs procedures. The Court recognizes that taxpayers are holders of fundamental rights, including:
- Due process
- Legal certainty
- Access to effective remedies
- Presumption of innocence
- Right to be heard
- Legality and specificity: All tax obligations must be clearly established by law.
- Proportionality and fairness: Sanctions must not be excessive relative to the infraction.
- Due process: Taxpayers must have the opportunity to defend themselves and challenge authority.
- Presumption of innocence: No one should be treated as guilty without a final ruling.
- Legal certainty: Rules cannot be changed arbitrarily during a procedure.
- Access to justice: There must be access to independent, impartial courts to review administrative actions.
Despite the constitutional and international framework, many administrative authorities continue to operate under a limited view of tax law, wrongly assuming that human rights only apply in criminal or civil cases.
This reflects an institutional culture that prioritizes control and revenue over the protection of taxpayer rights. Furthermore, the lack of training in human rights within tax and customs agencies, along with budgetary and political pressure to increase collections, creates disincentives for respecting fundamental guarantees.
Tax modernization in Mexico must not come at the expense of the rule of law. It is both possible and necessary to harmonize tax efficiency with human rights protections. To achieve this, the system must adopt:
- Mandatory human rights training for tax/customs personnel
- Institutional protocols to guarantee due process
- Internal oversight bodies to prevent abuse of authority
- Strengthening of tax and administrative courts with a rights-based approach
In a democratic state, tax power cannot be exercised without limits. Human rights are not optional in tax matters—they are a constitutional imperative. Enforcing them in tax and customs procedures does not weaken the state; it legitimizes its actions and protects individuals from abuse.
The strength of Mexico’s tax system lies not in the severity of its sanctions, but in its ability to enforce the law with fairness, legality, and respect for fundamental rights.
