Mexico says it is not raising taxes. It is capping what companies can deduct, which produces the same 140 billion pesos by a different route.

The revenue side of Mexico’s 2027 economic package, presented on 8 September, rests on limiting what companies can deduct rather than on any new levy.
What Actually Changes
The package caps corporate tax deductions and cuts the limit on deductible interest from 30 percent to 20 percent. The finance ministry estimates the combined yield at close to 140 billion pesos.
It applies to firms with revenue above 50 million pesos. Small and micro businesses, and companies less than five years old, are exempt.
The interest-deductibility change tracks OECD recommendations on base erosion and profit shifting, which is the technical justification for describing it as anti-avoidance rather than as a tax increase.
It was presented by Finance Secretary Edgar Amador Zamora, with revenue undersecretary Carlos Lerma and SAT head Antonio Martínez Dagnino. President Claudia Sheinbaum’s framing was unambiguous: there will be no new taxes.

The Framing Argument
Whether a deduction cap is a tax increase is a question of definition rather than of arithmetic. A company that could deduct an expense last year and cannot this year pays more tax. The rate did not change.
The government’s position is that the deductions being closed were being used to reduce liability beyond what the law intended, and that recovering them is enforcement rather than taxation.
That is a defensible reading of the interest limitation in particular, which is the kind of measure OECD members have been adopting for a decade specifically because interest deductibility is the easiest lever for shifting profit out of a jurisdiction.

What the Critics Say
Gustavo de Hoyos Walther, writing in El Financiero, put the objection this way: it has become a habit, the adjustment path is announced, it is not met, and the same path is announced again for the following year.
CIEP argued that isolated increases to the excise regime are temporary patches against a problem that requires a comprehensive restructuring of public finances. Coparmex called for actual compliance with fiscal commitments rather than temporary fixes.
Jorge Cano of México Evalua and Iván Arias of Banamex both warned that rating agencies have flagged slow deficit reduction as a risk to Mexico’s investment grade.
The common thread is not that 140 billion pesos is the wrong number. It is that a revenue measure of this size arrives instead of the structural adjustment that has been promised in successive packages.
