Madrid’s garbage tax has been overturned by the courts, upholding the appeals that challenged its implementation and reigniting a political debate that has been raging in the capital for months. The decision comes after a legal offensive led by the opposition and certain institutions, which had already sought its annulment on the grounds that it was an unfair, ill-calculated, and poorly conceived measure from the outset.
The Madrid High Court of Justice has overturned the 2025 ordinance on the grounds that “an essential part of the technical-economic report serving as the basis for determining the tax was omitted during the public consultation process.” The ruling affects the first installment of this tax in the capital, which began to be collected in September of last year and sparked strong neighborhood discontent due to the significant differences in amounts between neighborhoods.
The crux of the conflict lay not only in how much was paid, but in how the system had been constructed. Más Madrid argued that the City Council had combined criteria in a non-transparent manner, with 80% linked to the cadastral value and 20% to waste generation per neighborhood—a formula that, in their view, penalized lower-income families and districts.
Opposition to Madrid’s garbage tax
From the outset, the opposition argued that the tax failed to meet its environmental objectives and did not incentivize recycling. The central argument was that the formula used did little to reward sustainability and, instead, punished many families with bills that could skyrocket depending on their neighborhood of residence.
Más Madrid also warned that the fee structure had been designed without sufficient social safeguards, without clear discounts for vulnerable households, and without effective mechanisms to penalize major waste generators such as packaging or certain economic sectors. That political criticism has now been reinforced by the court ruling, which invalidates the ordinance and calls into question the entire scheme approved by the City Council.
The Madrid High Court of Justice’s ruling is not final; that is, it can still be appealed by the Madrid City Council to higher courts.
