NYC’s First Pied-à-Terre Tax Bills Are Coming—and Buyers Are Recalculating

New York City's new tax on high-value second homes was designed to raise revenue. But changes to the tax code can also influence how people buy and sell property.

"There's always the risk of avoidance," explains Jake Krimmel, senior economist at Realtor.com®. "Tax bases are famously mobile—especially across municipal boundaries—and that's doubly true for wealthier individuals."

With the first surcharge bills expected to be mailed in the coming days, Realtor.com analyzed the nearly 1 million property and residential-unit records in the city's supplemental tax roll, identifying 24,218 potentially exposed homes that met the relevant valuation thresholds.

Of those, 2,536 (10.5%) sat within just 5% above the minimum valuation required for taxation, while 560 (2.3%) fell within 5% on either side of a higher tax-rate threshold.

Which side of that divide a home falls on can come with huge financial stakes for owners—and agents say buyers are already taking notice.

"The biggest change since July is that buying a second home in New York has become a much more calculated decision," says Donald Brennan, a real estate broker with Engel & Völkers.

It’s easy to see why.

In at least one building, two apartments with government-assigned market values just $6,009 apart could face a $37,813 difference in annual surcharges simply because they fall on opposite sides of a tax-rate threshold—assuming neither qualifies for an exemption.

The tax base might not be as big as it looks

New York City has long attracted wealthy buyers looking for a second residence, whether for work, leisure, or the opportunity to spend part of the year in the city.

"I might be biased, but it's a fantastic place to live, especially if you can afford it," says Krimmel.

His caveat is telling: if you can afford it. With an estimated 52% of New York City renters already burdened by housing costs, wealthy second-home owners present a tempting target for Mayor Zohran Mamdani’s tax-the-rich agenda.

But the new tax will add considerable expense even for those who can afford multiple homes.

For condos and co-ops, the surcharge starts at 4% of their Department of Finance market value at $1 million. One- to three-family homes face an initial rate of 0.8% beginning at $5 million.

The city values houses using comparable sales but condos and co-ops based on their potential rental income, so their tax thresholds aren't directly comparable. At either entry point, however, the annual surcharge starts at approximately $40,000.

Brooklyn accounts for 560 of the 713 Class 1 properties just above the minimum threshold, while Manhattan accounts for 1,700 of the 1,823 condo and co-op units in the equivalent position.

But local brokers point out that many of these properties may never face the surcharge at all.

"In Brooklyn, I think this creates a slightly different conversation because so many of our luxury buyers are purchasing homes they actually intend to live in," says Jessica Peters, a Brooklyn-based broker with Douglas Elliman.

Already, thousands of owners have secured exemptions from the new tax. Of approximately 17,000 notices mailed to owners, close to 11,000 exemption applications had been submitted and more than 8,800 approved as of Oct. 29, Gothamist reports.

That leaves a great deal of uncertainty around how much revenue the city will actually be able to bring in.

While the city budgeted $500 million in annual revenue from the new tax, an April report from City Comptroller Mark Levine warned that exemptions and other behavioral changes could reduce collections to between $340 million and $380 million.

But exemptions aren't the only factor affecting what owners could owe. There's also the matter of the threshold values.

Condo and co-op rates rise to 5.25% above $3 million and 6.5% above $5 million. Rates for one- to three-family homes, meanwhile, increase to 1.05% above $15 million and 1.3% above $25 million.

And because the higher rate applies to the property's entire value, even a small difference in valuation can trigger a monumental increase. The owner of a $3 million condo or co-op subject to the 5.25% rate, for example, would owe just over $157,000.

These higher-rate thresholds have a much narrower geographic footprint, too. Of the 270 records sitting within 5% above a higher-rate threshold, 264 are in Manhattan, including 33 in ZIP code 10022 and 29 in 10021.

Krimmel says owners could respond by reconsidering where they buy or how they use their properties.

"The question is whether there are other places which act as a close substitute for the newly taxed properties," he says.

Brennan sees that calculation emerging among buyers who may spend only a few months a year in New York.

"When you're looking at a multimillion-dollar apartment that you might only use a few months out of the year, that additional tax becomes part of the conversation very quickly," he says.

Some may decide to rent rather than purchase, he adds.

Those decisions could ultimately help free up housing for other buyers or tenants, as Krimmel notes. At the same time, those sales could also reduce the number of properties generating surcharge revenue.

How a few thousand dollars can change the calculation

Owners are also challenging the tax in court. Three lawsuits have been filed, two of which remain pending.

A Nov. 4 appeals court ruling dismissed a lawsuit challenging the city's rollout on standing grounds, while the remaining cases challenge its constitutionality.

But homeowners don't need to overturn the law to challenge what they might owe. They can also dispute the city's valuation of their properties—and for those sitting just above a tax threshold, even a small adjustment could eliminate the surcharge entirely.

Narrowing the analysis to properties within just 1% of a tax threshold identified 602 records, including 496 just above the minimum valuation required for taxation.

An additional 106 records fell within 1% of a higher-rate cutoff, including 61 just below and 45 above. All were in Manhattan, and of those, 66 were condos or co-ops near the $3 million threshold, where the annual surcharge increases from 4% to 5.25%.

From a bird's-eye view of the city, those differences might seem negligible. But when looking at a specific building, they are more dramatic.

At 111 West 57th St., a luxury condominium tower near Central Park, unit 57 has a DOF market value of $2,999,794—just $206 below the higher threshold. Unit 38, meanwhile, is valued at $3,005,803.

That $6,009 difference in valuation translates to a $37,813 difference in potential annual surcharges, with the higher-valued apartment facing a charge of approximately $157,805.

A similar disparity appears at 768 Fifth Ave., where two units separated by $19,337 in DOF market value face a $38,317 difference in potential annual charges.

That’s no small sum, even for a wealthy homeowner.

"If they're already paying substantial carrying costs, they're going to look for ways to offset that expense, whether through the purchase price or other concessions," says Ben Jacobs, a Douglas Elliman broker specializing in Manhattan and Brooklyn.

A lower asking price wouldn't automatically reduce the government's valuation or the tax owed, but it could help buyers offset the cost of carrying the property.

Krimmel sees another potential consequence: The surcharge could change what economists call a property's option value—the value of being able to use it differently in the future. Condominiums, for instance, typically offer more flexibility to rent out than co-ops, making that potential rental income part of what a buyer is purchasing.

The same principle could apply to homes that buyers might eventually want to use as second residences.

Even if a property is exempt today, the possibility of a future surcharge could become another consideration in negotiations. Jacobs adds that uncertainty can create its own complications.

"Buyers want to know exactly what their exposure will be before they commit," he says. "When those answers aren't immediately clear, it can slow down a transaction."

Is the tax already changing the market?

To his point, there are early signs of a sharper slowdown in New York City's luxury condo and co-op market since the city began notifying potentially affected property owners in July.

New condo and co-op listings initially priced between $1 million and $3 million fell 11% year over year from July through Nov. 7, compared with a 1% increase between April and June, according to an analysis of Realtor.com listing data.

The decline was even steeper among properties priced between $3 million and $5 million, where new listings fell 16% year over year after July, following a 5% decline in the preceding three months.

By comparison, new listings priced below $1 million fell just 1% year over year since July, after rising 7% between April and June.

Of course, the pied-à-terre tax can’t shoulder all the blame for the slowdown. The luxury market was already showing signs of weakness before the city began sending tax notices, and rising mortgage rates have added another headwind.

Brokers, meanwhile, say some second-home buyers are approaching purchases with greater caution.

"I don't think this means wealthy buyers are suddenly abandoning New York. They still want to be here," Brennan says. "But they're looking much more closely at the numbers."

Peters expects some prospective second-home buyers to delay their decisions or consider renting until they have a better understanding of their potential tax bills.

"What concerns me more is how the additional cost could influence decisions before buyers even start looking," she says.

The first surcharge payments are due on Jan. 1, 2027, and the larger market response—if there is one—will likely take even longer to untangle from the myriad other factors affecting buyer and seller behavior.

But for now, two things are clear: Thousands of potentially affected properties sit close to tax thresholds with huge financial consequences, and new luxury condo and co-op listings have slowed considerably since the city began notifying owners.

Whether those developments are connected—and whether the tax ultimately changes the number of second homes in New York City—remains to be seen.
