New York City homeowners have been given an additional month to establish their primary residency status following widespread confusion surrounding the city's rollout of a new pied-à-terre tax and the publication of a public real estate database tied to the measure, as reported by Fox Business.

The extension comes after the New York City Department of Finance (DOF) released a public tax roll listing the names and addresses associated with more than 960,000 properties across the city's five boroughs. The database was published as part of the implementation of New York state's new tax on certain non-primary residences.

The pied-à-terre tax was approved by state lawmakers in May and signed under Gov. Kathy Hochul. The measure applies to non-primary residences valued at more than $5 million, along with condominiums and cooperative apartments valued at $1 million or more. Initial state estimates projected that between 13,000 and 31,000 properties would ultimately be subject to the tax.

The significantly larger public property list prompted questions from homeowners about whether they would be affected, leading city officials to extend the deadline for residents to verify their primary residence status.

David Arditi, founding partner of Aria Development Group, said the city needs to provide greater certainty as implementation continues.

"Policymakers need to be honest about the trade-offs and what drives the local economy," Arditi told Fox News Digital. He warned that if higher-income taxpayers relocate, "it doesn't just hit the people who left, it shows up much more prominently in the budget of those who will stay behind."

Arditi added, "Every city that leans this heavily on a small group of high earners has to reckon eventually with this possibility. New York still continues to have real staying power, but we're clearly in a moment where that's being tested."

The Department of Finance's published property roll also included numerous well-known public figures, drawing additional attention to the rollout.

Individuals appearing on the list included U.S. Secretary of Commerce Howard Lutnick, President Donald Trump's niece Mary L. Trump, filmmaker Woody Allen, longtime Vogue editor-in-chief Anna Wintour, actress Cynthia Nixon, New York City Councilwoman Gale Brewer and Staten Island City Councilman Joe Carr.

Arditi said large municipal initiatives often experience implementation challenges but argued that officials should provide homeowners with a clearer explanation of who is actually affected by the tax.

"That's the difference between precision and accuracy. I would expect some inefficiency rolling out any municipal initiative at this scale," Arditi said. "But when your list comes in 30 times bigger than what was estimated, city officials need to give homeowners real clarity on who's actually impacted and why."

Beyond the immediate confusion, Arditi said uncertainty surrounding the tax has become part of broader conversations with prospective buyers evaluating whether to invest in New York real estate.

"I'll leave the security implications to the experts, but I can tell you, since talk of this tax started earlier this year, I've had no shortage of conversations with people who were seriously reconsidering New York as a place to invest," he said.

He also pointed to continued migration to Florida among some buyers considering leaving New York.

"The great thing about New York is there's never a shortage of buyers. Having said that, given the current political and socio-economic climate in New York City, I expect the exodus to Florida to keep gaining traction," Arditi said.

"I saw it play out myself this summer. Plenty of soccer fans from the Northeast were down here for the World Cup, and some of them were, in between matches, scouting what's available in case they decided to make the move — and that was before this list came out."

According to Arditi, recent headlines have painted mixed pictures of Manhattan's luxury housing market. While some reports have suggested weakness at the top end of the market, others have indicated continued strength in high-end sales.

He said South Florida has shown particularly strong momentum during 2026.

"The headlines from the last few months have been mixed. One story says Manhattan's top end is cratering, while another report shows it's very resilient and continues to perform well. In South Florida, though, the numbers are pretty clear. Miami has already outsold New York in ultra-luxury deals this year, something that would've been unthinkable not long ago," Arditi said.

"And what we're hearing on the ground matches that, as our sales teams have been fielding calls from more motivated New York buyers."

The residency extension gives homeowners additional time to demonstrate that their properties qualify as primary residences while city officials continue implementing the new tax program.
