NYC ordered to scrap Mamdani’s pied-à-terre tax rollout

A Staten Island judge has ordered New York City to restart the rollout of its new tax on high-end second homes, dealing a setback to one of Mayor Zohran Mamdani’s signature revenue measures. New York City’s planned tax on secondary homes was dealt a major setback Tuesday after a Staten Island judge ruled in favor of the plaintiffs challenging the rollout.

What the judge ruled

Judge Wayne M. Ozzi of Richmond County ruled the roll must be removed from the website, but can be replaced with a secondary roll reflecting those properties actually subject to the surcharge. Previously mailed notices must be canceled as well.

Ozzi ruled that the city shifted the burden onto homeowners to prove they live in their properties and failed to use information already available to the Finance Department, invalidating the notices already mailed and directing the city to replace the sprawling supplemental roll with a narrower list based on a more individualized review.

The tax itself

The pied-à-terre tax places a surcharge on non-primary residences in New York City valued over $5 million, as well as co-ops valued at $1 million or more, and was rolled out as part of Mayor Zohran Mamdani’s 2027 fiscal year budget in an attempt to close the city’s budget gap.

Signed by Gov. Kathy Hochul in May at Mayor Mamdani’s request, the tax aims to address a $5 billion budget gap by generating $500 million annually. The plaintiffs did not challenge the legality of the tax itself, but rather the rollout.

How the rollout went wrong

The city’s Department of Finance website posted a tax roll in July that included names and addresses of over 900,000 New York City homeowners, even if they were not subject to the tax.

The Department of Finance erroneously mailed 17,000 letters to homeowners, later determining that nearly 6,000 properties, or 35%, were actually primary residences exempt from the surcharge after failing to check personal income tax filings.

What happens next

The city has said it will appeal, and the tax faces a second legal challenge. Casino executive Steve Wynn and former U.S. Commerce Secretary Wilbur Ross, along with Ross’s wife, filed a separate lawsuit arguing the levy unconstitutionally targets wealthy nonresidents. The pair say they already pay substantial property taxes and use fewer city services than full-time residents.

Implementation remains in flux while the city prepares new notices and pursues an appeal. The original October 6 exemption deadline is effectively frozen while the process is redone.
