A federal judge slapped down New York City Mayor Zohran Mamdani’s new tax on wealthy New Yorkers.

This is a good development in the fight against the socialist mayor whose campaign against the rich could bankrupt the most prosperous city in America.

What Happened

Yesterday, a Staten Island judge paused implementation of the city’s new pied-a-terre tax. He mandated the Department of Finance remove 960,000 properties from the tax roll it published last month as part of the tax rollout. Also, he banned the city from enforcing the tax warnings they mailed homeowners.

This ruling effectively grinds Mamdani’s pied-a-terre tax to a halt, stopping the aggressive action. The ruling was in response to a lawsuit filed late last week by a group of three homeowners. 

The judge’s order is a victory for New York City residents, but only a temporary one. The next hearing is scheduled for the end of August, and the city has announced its intention to fight the lawsuit. Importantly, the lawsuit does not challenge the merits of the pied-à-terre tax but the city’s rollout. We can imagine that Mamdani’s team is devising workarounds and other rollout plans.

Background

New York City’s pied-à-terre tax is an annual property tax surcharge on residential properties valued from $1 million to $5 million that are not the owner’s primary residence. These properties include one- to three-family homes, co-ops, and condos. The tax, which took effect July 1, 2026, is Mamdani’s solution to taxing the rich to fund his expansive agenda. 

The Mamdani administration estimated that the pied-à-terre tax would yield $500 million per year, but the city’s Comptroller Mark Levine’s office said the real figure would be closer to $340 to $380 million and could diminish over time.

How the city unveiled the new surcharge and is rolling it out has been contentious. Tax warning letters were sent out to about 17,000 homeowners recently. Homeowners have until mid-September to challenge the tax and prove to the city that their assessment is incorrect. They must show records—which some argue the government already has access to—to dodge this new tax bill, such as tax returns, driver’s licenses, voter records, and utility bills to the city. 

That was not the only aspect of the rollout that triggered backlash. Mamdani and his administration have doxxed the targets of the pied-a-terre tax through a name-and-shame campaign. In a bold move, the city published a list of names and addresses of the new tax targets on the city’s website. 

The New York Post counted over 960,000 residences and individuals listed as potentially in line to be hit with the pied-à-terre tax, far above the 13,000 homes NYC Mayor Mamdani and New York Governor Kathy Hochul initially sold to the public. Many of the addresses are not in the wealthiest part of the city, but include middle-class neighborhoods.

In a viral social media video, Mamdani announced the tax in front of one of the city’s wealthy residents whom he was targeting:

This public doxxing campaign is not just bold, it’s dangerous. Given that Luigi Mangioni is currently on trial in New York for the assassination of a healthcare executive, simply because the CEO was wealthy, the mayor should turn down the volume on violent political rhetoric against wealthy New Yorkers. What’s to stop an unhinged person from turning the names and addresses on the city’s website into a kill list?

Steven Fulop, president and CEO of nonprofit business advocacy group the Partnership for NYC, called the doxxing campaign “a mistake, and a dangerous precedent.” Adding, “Publishing names and addresses singles out people who have done nothing wrong, at a moment when the far-left already treats success itself as something to be punished.”

What This Means

New Yorkers are waking up to the reality that many of the names listed are not billionaires, but successful people who worked hard to buy a second home. Penalizing success drives successful people away. 

This exercise also reveals the truth about the socialists’ plans to tax the wealthy to fund expansive spending programs: there’s never enough money to shake down from the ultra-wealthy. They have to move further down the income ladder to find sources of income. In this case, it’s the deli owner who managed to purchase a second home that he might rent out from time to time for extra income. 

Soaking the rich is a fun slogan until everyone else realizes they’ve been wrung dry.
