Appeals Court Rules NYC Can Proceed with Second-Home Tax Collection Despite Legal Challenges

Appeals Court Rules NYC Can Proceed with Second-Home Tax Collection Despite Legal Challenges

by

An appeals court in Brooklyn ruled Wednesday that Mayor Zohran Mamdani’s administration can keep collecting New York City’s new tax on high-end second homes, reversing a lower court order that had forced the city to restart the rollout from scratch.

The ruling, issued by the Appellate Division of the New York Supreme Court, dismissed a lawsuit brought by homeowners who argued the city botched the implementation of the pied-à-terre surcharge. The court’s written decision found that the plaintiffs lacked legal standing, overturning a September 29 ruling by a Staten Island judge who had ordered officials to start the process over.

A Tax Built on Campaign Promises

The surcharge, approved by the New York State Legislature in May, targets second homes valued at $5 million or more for one- to three-family properties and $1 million or more for condos and co-ops. The city’s Department of Finance sent initial determination notices to roughly 17,000 property owners in July, setting off a wave of legal resistance from wealthy residents who say the tax punishes people who already pay property taxes while maintaining homes elsewhere.

Mamdani embraced the tax during his mayoral campaign as a direct way to fulfill his promise to “tax the rich” and help close the city’s budget gap. The revenue is meant to fund safer streets, cleaner parks, and essential services, the mayor’s office has said. After the Staten Island judge sided with homeowners in September, the city appealed while continuing to roll out the tax anyway—a gamble that paid off Wednesday when the appellate panel in Brooklyn reversed the lower court’s decision.

“From Day 1, those with the most have attempted to use every legal avenue available to shield their wealth and avoid contributing more to our city,” Mamdani said in a statement Wednesday.

Standing, Not Merits, Decides This Round

The appellate judges did not rule on whether the tax itself is legal. Instead, they found that receiving an initial tax notice or appearing on the city’s property valuation list did not establish sufficient concrete harm to justify the lawsuit, Fox News reported. The court also rejected arguments that the rollout caused injuries through privacy concerns or the costs of seeking exemptions.

Randy Mastro, the attorney representing the homeowners who brought the case, criticized the panel for taking what he called a “procedural offramp” by dismissing the suit on standing rather than addressing the merits. In a statement, Mastro called the city’s rollout “lawless and chaotic” and said the data collection scheme would “go unremedied” for now. He did not say whether his clients plan to appeal to the state’s highest court, but he predicted that challenges to the tax’s constitutionality—the central argument in other pending lawsuits—would ultimately prevail.

What Comes Next for the Pied-à-Terre Tax

This victory clears one hurdle, but the tax is far from safe. Separate legal challenges remain active, including one arguing that the surcharge discriminates against people who live outside New York in violation of the U.S. Constitution. That case is expected to be heard next month. The administration is also defending the tax against challenges in Suffolk County, and Mamdani’s lawyers are simultaneously fighting to uphold other campaign promises, including a rent freeze on rent-stabilized apartments.

For the roughly 17,000 property owners who received initial notices, the practical effect is immediate: the city can continue collecting the surcharge while those other cases play out.

Whether the tax survives its next court date will depend on whether judges find the surcharge constitutional—a question this week’s ruling deliberately left unanswered.
