Refund of the Real Estate Acquisition Tax in Mexico City

17/10/2025

Mexico’s Federal Judiciary has declared the calculation method of the Real Estate Acquisition Tax (ISAI) in Mexico City unconstitutional, allowing taxpayers to recover unduly paid amounts.

This ruling enables taxpayers who paid the ISAI between 2021 and 2024 to request a refund, even without having filed amparo proceedings. In this Legal Briefing, Pérez-Llorca Mexico’s Tax team analyzes the implications of this decision and outlines the legal strategies available to effectively secure the recovery of overpaid taxes.
