Appeals Court Dismisses Challenge to NYC's Second-Home Tax Rollout

A New York appeals court has dismissed a lawsuit challenging the rollout of New York City's tax on high-value second homes, finding that the homeowners who brought the case had not shown a concrete injury that gave them the legal right to sue.
The unanimous ruling by the Appellate Division, Second Department, reversed a September 29 judgment that had granted the homeowners relief. The November 4 decision concerns standing, not a ruling that settles the merits of every challenge to the tax.
Seven homeowners sued over the city's publication of a supplemental property roll and notices sent to owners who might owe the surcharge. They argued that the process wrongly required owners to prove that their properties were primary residences.
The court found that appearing on the roll or receiving an informational notice was not enough to establish the required injury. Two petitioners had not alleged that they received notices, while the other five received exemptions after the lawsuit began.
Mayor Zohran Mamdani welcomed the ruling and said the city would continue defending the surcharge. The tax targets second homes worth more than $5 million.
Other legal challenges remain. The ruling does not resolve those separate cases or establish that every aspect of the city's tax and exemption process is lawful.
