New York Judge Halts Second-Home Tax Rollout, Forcing City to Start Over

The Rollout Goes Wrong

What sank the city's effort wasn't legal opposition to the tax itself. Three homeowners sued over how the city executed the policy. They alleged their primary residences were incorrectly flagged as taxable properties. Some received notices at their main addresses suggesting they might owe money on homes they actually live in. Others discovered their names on published tax rolls despite owning no secondary properties.

"The Mamdani administration didn't do the work the statute requires," attorney Randy Mastro told reporters, representing the plaintiffs. "Instead, they shifted the burden to thousands—even hundreds of thousands of New Yorkers—to prove they live in their own homes."

The judge agreed. Her ruling found that the city's approach "unfairly shifted the burden to thousands of homeowners." All previous notices are now void. Officials must send new letters identifying specific properties subject to the tax.

A Setback for Campaign Promises

Mamdani, who took office in January, had already notched one early policy win—a rent freeze for stabilized apartments citywide. The pied-à-terre tax was meant to cement his image as a mayor willing to squeeze the wealthy. He even filmed a video outside an apartment building owned by billionaire financier Ken Griffin, declaring: "Today, we're taxing the rich."

But implementation matters. A city spokesman confirmed Mamdani's office will appeal the ruling, signaling a legal fight ahead. Other lawsuits challenging the tax's constitutionality are pending, though this decision focused only on procedural flaws.

The tax remains law. The court order simply forces the city to do what it should have done from the start: identify affected properties correctly, notify owners with precision, and let them respond before assessment begins.
