Part of Claudia Sheinbaum leads the government in Mexico.

How could the opposition's efforts to block Sheinbaum's majority affect Pemex?

Possible What happens if… A possibility worth considering, not a forecast.

Pemex's profitability may be affected by pending tax reform changes The opposition's efforts to prevent Claudia Sheinbaum's legislative majority could determine whether the proposed 2027 tax reform passes the Senate and becomes law. If the reform is enacted, it would introduce changes to the income tax law (ISR) that affect large Mexican firms. Specifically, the reform would cap deductions for companies with yearly income above 50 million pesos at 96.67% of their income. Furthermore, it would cut deductible net interest to 20% of a firm’s adjusted taxable profit, down from the current 30%, potentially increasing Pemex's tax bill and operational costs.

The facts so far

As reported. Each one links to where it comes from.

  • The Mexico tax reform plans for 2027 cleared the lower house of Congress on 14 October.riotimesonline.com
  • The reform adds a new chapter for firms with yearly income above 50 million pesos and a taxable profit.riotimesonline.com
  • Firms covered by the new chapter can deduct only up to 96.67% of their income if deductions exceed that line.riotimesonline.com
  • The tax reform cuts deductible net interest to 20% of a firm’s adjusted taxable profit, down from 30% now.riotimesonline.com

Why it matters

The tax reform represents a significant shift in Mexico's fiscal policy, targeting evasion through fake invoices and aiming to raise more revenue. For large corporations, the changes to deduction caps and interest limits mean that firms that are heavy borrowers or have old losses face a higher tax bill starting in 2027.

The political fight over this legislation highlights the ongoing tension between the government's agenda and the opposition's desire to maintain legislative checks and balances. The Senate vote is the critical next step, as the law is not yet guaranteed to pass, meaning the financial impact on large entities like Pemex remains contingent on the political outcome.

What we don't know yet

  • Will the Senate approve the tax reform bill as currently written?
  • What specific rules will the tax office (SAT) issue regarding the application of the new limits?
