New York City's "non-primary residence tax" imposed on luxury second homes (pied -à- terre tax) has encountered obstacles, with the focus of the controversy being a list previously published by the city that covered hundreds of thousands of residences.

A judge on Staten Island ruled on Tuesday that the previously published list of residential properties in New York City should be removed. Instead, the New York City Finance Department ( Department of Finance , abbreviated as DOF ) can replace this lengthy list with a register that only includes properties actually subject to this tax. In addition, the tax notices sent to those who may be owners of such taxable properties should also be cancelled, and notices should be issued to the actual affected properties instead.

Judge Wayne M Ozzi wrote: 'This does not involve a crime, but the way DOF is implementing this tax law is causing significant harm to homeowners and making them suffer punishment unnecessarily.'

This ruling stems from a lawsuit filed by a group of New York homeowners regarding the implementation of this tax. The plaintiffs claimed that this approach caused "widespread chaos" and "contributed to, induced, and amplified unnecessary scrutiny of homeowners' personal information from the public." This ruling is precisely aimed at this controversial implementation process. The judge stated that mailing notices "recklessly and unnecessarily caused homeowners to spend time and money," and moreover, "the burden of proving their basic residential status was unfairly shifted to thousands of homeowners."

"Non-primary residence tax" triggers a legal tug-of-war in New York

The ruling of that day marked the latest development in the intense legal battle surrounding this tax issue. At the end of July, the New York City Finance Department sent letters to 17,000 homeowners who may be required to pay this tax. DOF also disclosed the addresses of 900,000 households, along with the names of the homeowners and the estimated values of their properties.

On August 10th, a judge temporarily halted the further implementation of this tax, ordering New York City to remove the list of addresses and suspend the enforcement of any related deadlines. Previously, homeowners had until September 18th to file appeals regarding the property values calculated by the city government or to prove that the residence was their primary home.

The three core plaintiffs in this lawsuit are from Staten Island and Manhattan in New York City. They stated that they felt uneasy after receiving the letters and discovering that their names were listed in a public database.

In addition to the ruling on Tuesday, another new lawsuit targeting this tax was filed on Monday. The plaintiffs are individuals who reside in Florida but own property in New York, including former U.S. Secretary of Commerce Wilbur Ross Jr, his wife Hilary, and businessman Stephen Wynn. The lawsuit claims that this tax is unconstitutional at both the state level of New York and at the federal level.

The mayor's office stated that this tax will generate $500 million annually to support Mamdani's ( Mamdani ) affordability agenda. The city government has also hired an additional 24 staff members to handle complaints and residents' questions regarding the implementation process.

This tax is levied on a progressive basis and applies to non-primary residences valued at at least $5 million as determined by DOF, as well as apartments and cooperative apartments valued at at least $1 million ($co-op). The additional tax rate starts at 0.8%, and for properties valued at $25 million or more, the tax rate rises to 1.3%.

According to the calculations of Business Insider, Citadel's CEO and Miami resident, Ken Griffin, will need to pay approximately $1.3 to $1.4 million for his apartment located in Central Park South. Celebrities and billionaires such as Donald Trump, Jeff Bezos, Jay-Z, and Beyonc may also be required to pay this tax.

Lawyers and real estate agents interviewed by journalist James Rodriguez stated that this tax leaves high-net-worth home owners with little room to avoid it. Unless they have immediate family move in to the address or can successfully prove that the value of their property is lower than the municipal government's assessment, these "would-be New Yorkers" should not expect to be exempted.

At present, unless New York City is able to successfully obtain a stay of execution order, it may have to redesign the implementation plan for this tax.
