41–91%
For 2025–2026 investments, the decree sets immediate deduction rates of 41–91% according to the asset or activity. It also provides an additional deduction of 25% of the increase in eligible training or innovation expenditure over the previous three-year average. It does not reduce the income tax rate.
30%
LISR art. 202 provides a 30% credit against income tax on the increase in R&D spending and investment over the average of the previous three tax years. Statutory caps: MXN 50 million per taxpayer and MXN 1,500 million annually in total.
VAT
Eligible credit balances may be claimed from SAT with the required documentation. Timing depends on the procedure, information requests and review powers; a ten-day refund is not promised.
Anáhuac
Within Nuevo León, only Anáhuac is included. VAT may fall from 16% to 8% for eligible transactions; the income tax credit equals one third of the tax, in the proportion attributable to regional revenue. Each incentive has separate requirements and exclusions.
Poles
The regime provides immediate deductions and training and innovation tax incentives under its conditions. Location within a declared pole and authorization must be established; this page confirms no individual Nuevo León property's eligibility.
Financing· Not a tax exemption
Credit
Provide business and investment financing schemes. The financial institution assesses credit and sets terms; this is neither a tax exemption nor guaranteed funding.
