Judge Temporarily Blocks Rollout of Mamdani’s Pied-à-Terre Tax
New York City Mayor Zohran Mamdani’s effort to expand taxation on property owners has encountered a major legal setback only months into his administration.
A Staten Island judge on Monday temporarily blocked implementation of the mayor’s pied-à-terre tax while a lawsuit challenging the city’s rollout moves forward.
The Mamdani administration immediately sought permission to appeal, a procedural move expected to stay the lower court’s order while litigation continues.
“The City will continue with the pied-à-terre’s implementation,” mayoral spokesperson Matt Rauschenbach said.
The temporary restraining order directed New York City to remove the public tax roll associated with the program and prohibited officials from sending additional notices while the order remains in effect. The next hearing is scheduled for Aug. 31.
Judge Finds Potential Irreparable Harm
The judge said from the bench that the city’s notices caused irreparable harm by failing to explain why particular homeowners had been identified as potentially liable for the surcharge.
Recipients were warned that they could face taxation unless they applied for an exemption, even though many reportedly used the affected properties as their primary residences.
Only hours before the ruling, Mamdani promised that his administration would “vigorously defend” the program.
“We disagree with today’s ruling, but we are confident in both the pied-à-terre surcharge and the City’s ability to implement it fairly and effectively,” Rauschenbach said following the decision.
The surcharge applies to non-primary residences in New York City valued at $5 million or more. Condominiums and cooperative apartments valued at $1 million or more can also fall within the program.
The tax was incorporated into the state budget and signed into law by Democratic Gov. Kathy Hochul in May as part of an attempt to close New York City’s budget gap. Hochul had announced the proposal with Mamdani in April.
Mamdani, a democratic socialist who took office in January, made higher taxes on wealthy New Yorkers a central feature of his campaign and broader affordability agenda.
Lawsuit Challenges Implementation, Not Tax Itself
Homeowners Simon Hedley, Rachel O’Brien and Carmine Morano filed the lawsuit Friday in state Supreme Court in Richmond County.
They allege that the Department of Finance incorrectly flagged their properties as potentially subject to the new surcharge despite the homes being their primary residences.
The plaintiffs are not challenging the legality of the tax. Instead, their case focuses on what they describe as a deeply flawed and overly broad implementation process.
As part of the rollout, the city published a tax roll containing names, addresses and property values for more than 900,000 residential properties—including homes that were not subject to the surcharge.
Approximately 17,000 property owners then received letters informing them that they might owe the new tax.
The decision to publish such extensive property information and force homeowners to prove their eligibility for an exemption has raised serious questions about privacy, accuracy and basic administrative competence.
“We are very gratified by the judge’s decision, which has vindicated the rights of hundreds of thousands of New York City homeowners who were subjected to a process they never should have been a part of in the first place,” plaintiffs’ attorney Randy Mastro said.
Mamdani Supporter Says City Cast an Excessively Wide Net
Hedley presents an especially uncomfortable challenge for Mamdani because he says he supports the mayor and his policies, including increased taxation of wealthy residents.
Even so, Hedley believes the administration mishandled the tax’s implementation.
He purchased his Manhattan property 13 years ago and says it remains his only home and primary residence. Nevertheless, he received a notice in July warning that he could be subject to the surcharge.
“Part of my issue was, I feel it would have been pretty straightforward for the administration or the Department of Finance just to cross-reference the tax records and not send out the letters in the way they did,” Hedley said.
“It seems to be they were throwing a very large net over the situation,” he added, saying he and others “were nervous about it,” CNN reported.
Hedley eventually applied for an exemption by uploading a tax return. He learned Monday morning that the city had approved his request.
His experience nevertheless illustrates the burden imposed by the rollout: The government apparently placed the responsibility on homeowners to establish that they should not be taxed, even when existing records could have identified their properties as primary residences.
The controversy highlights a recurring problem with the left’s tax-and-spend agenda. Even when politicians promise to target only the wealthiest residents, rushed implementation and sprawling bureaucracy can ensnare far more people than advertised.
Mamdani’s administration insists it will continue moving forward. The courts will now determine whether City Hall’s handling of the program respected homeowners’ rights and complied with the law.
