Senate approves 2027 Revenue Law with 1.7 trillion debt ceiling

The Senate of the Republic approved the Federal Revenue Law (LIF) for 2027 on October 27, 2026, with projected revenue of 10 trillion 636 billion 488.1 million pesos and authorization to contract net domestic debt of up to 1.7 trillion pesos. The general vote was 79 in favor and 34 against, according to La Razón.

The figure of 1.7 trillion pesos corresponds to the maximum ceiling and not to actual borrowing, Senator Manuel Huerta clarified during the debate, according to MVS Noticias. Of the total revenue, the LIF estimates 6 trillion 263 billion 886.8 million pesos from taxes, 702 billion 564.7 million from social security contributions and fees, and 1 trillion 479 billion 959.2 million from financing.

For the energy sector, the decree sets specific borrowing limits, according to ContraRéplica:

- Petróleos Mexicanos (Pemex): 160 billion 619.5 million pesos in net domestic debt and 5 billion 259.4 million dollars in external debt. - Comisión Federal de Electricidad (CFE): 16 billion 742 million pesos in domestic debt and 725 million dollars in external debt.

The federal ceiling of 1.7 trillion pesos contrasts with the latest official estimate of public sector debt, which the Center for Public Finance Studies of the Chamber of Deputies reported in its monthly monitoring of the Historical Balance of the Public Sector's Financial Requirements. The package also included the Federal Duties Law and changes to the Income Tax Law (ISR). During the debate, a reservation was accepted that excludes from the deduction control mechanism the automotive industry operating under a fiscal deposit for assembly, and extends an exception to gasoline and diesel sales permit holders, according to Proceso. Because of that change, the ISR bill returns to the Chamber of Deputies for review in the co-legislating chamber.

The LIF has already been sent to the Executive for publication. The next step in the budget process is the 2027 Federal Expenditure Budget, which will define the spending allocated to Pemex and CFE and which the Chamber of Deputies must still debate.
