New York Appeals Court Upholds Mamdani's Second-Home Tax
Confirmed
In Short: A New York appeals court has upheld Mayor Zohran Mamdani's second-home tax, dismissing a lawsuit by homeowners who lacked standing to challenge the law.
A New York appeals court has upheld Mayor Zohran Mamdani's second-home tax, dismissing a lawsuit by homeowners who lacked standing to challenge the law. The ruling allows Mamdani's administration to continue implementing the surcharge, a key part of his agenda to raise taxes on wealthy New Yorkers and help close the city's budget gap.
The four-judge panel unanimously dismissed the homeowners' lawsuit, finding that the plaintiffs lacked legal standing to bring the case. The court ruled that the homeowners had not demonstrated that the tax or the publication of property information had caused them a concrete injury.
Mamdani welcomed the ruling, accusing wealthy property owners of trying to avoid paying additional taxes. 'From day one, 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.
The appeals court found that the homeowners were required to establish 'a cognizable harm that is not tenuous, ephemeral, or conjectural, but sufficiently concrete,' which they had not. The court also rejected the homeowners' arguments that the process caused concrete injuries through privacy concerns or the costs of seeking exemptions.
Supporters estimate the measure could generate $500 million in annual revenue. Mamdani's office has estimated that the surcharge will raise around $500 million in tax revenue a year. The surcharge, approved by the New York state Legislature in May, applies to qualifying 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 approximately 17,000 property owners in July. The appeals court found that the plaintiffs lacked standing to bring the case because they had not demonstrated that the tax or the publication of property information had caused them a concrete injury.
The appeals court also rejected the homeowners' arguments that the process caused concrete injuries through privacy concerns or the costs of seeking exemptions. The court found that publishing the supplemental property roll did not establish a legal obligation or otherwise alter the homeowners’ rights.
Mamdani said his administration would continue defending the law against separate challenges in Suffolk County. 'The pied-à-terre surcharge asks those who can afford luxury second homes to contribute toward the safer streets, cleaner parks and essential public services that every New Yorker deserves,' he added.
What this adds
The ruling marks the latest development in a series of legal challenges to Mamdani’s effort to impose an annual surcharge on expensive properties whose owners do not primarily reside in New York City.
Background
A federal appeals court has rejected the Trump administration's attempt to stop counting 20,000 ballots in California.
A federal appeals court on October 26, 2026, rejected the Justice Department's (DOJ) request to segregate over 20,000 ballots from suspected noncitizen voters in California.
What's confirmed
- "From day one, 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.
- New York City Mayor Zohran Mamdani scored a legal victory Wednesday after a state appeals court cleared the way for his administration to continue implementing an annual tax surcharge on high-value second homes.
What's still developing
- "But now, this lawless and chaotic data collection scheme will go unremedied."
- He said his office would continue to fight similar suits playing out in Suffolk County, L.I., challenging the legality of the tax itself, “brought by some of the same uberwealthy interests whose arguments just lost in court today,” including Steve Wynn, the casino mogul and developer, and Wilbur Ross, President Trump’s former commerce secretary.
- The Daily News sought comment from Mastro, a former official in the Adams and Giuliani administrations behind several cases seeking to stop Mamdani from executing his progressive agenda.
- But they soon learned they were, in fact, exempt from the annual surcharge when the city obtained fresher tax data, but chose to proceed with their suit anyway, challenging the manner in which the tax had been rolled out, court documents state.
- Wayne Ozzi, a New York state judge in Richmond County, twice ordered the tax rollout halted, but the appeals court halted both decisions.
- “Ordered that the judgment is reversed, on the law, with costs, the amended petition is denied, and the proceeding/action is dismissed,” the court decision stated.
