NEW YORK, NY— New York City has begun the first real test of its new tax on luxury second homes, sending notices to property owners who could soon face an annual surcharge if they own a high-value residence in the City but claim a primary home elsewhere.
The mailings mark the first step in implementing the non-primary residence property surcharge, often called the "pied-à-terre" tax, after Mayor Zohran Mamdani and Gov. Kathy Hochul secured the measure as part of this year's state budget.
The tax applies to one- to three-family homes, condominiums and co-ops when the owner maintains a separate primary residence.
About 13,000 properties could qualify under the law, which targets homes valued above $5 million and is expected to generate at least $500 million in recurring annual revenue, according to city reports.
For owners receiving letters, the immediate impact is procedural.
The Department of Finance has launched a new website with eligibility tools, frequently asked questions and instructions for submitting documentation as the city begins determining which properties qualify.
"When I came into office, I made clear that our City would need long-term solutions to our city's long-term fiscal challenges," Mamdani said.
"On Tax Day earlier this year, I promised that we would tax the rich, and with our new pied-à- terre tax, that is exactly what we have done. Today is the first step in implementing this tax and collecting critical revenue to fund our parks, schools and libraries."
Department of Finance Commissioner Richard Lee said the agency has already mailed initial notices and expanded staffing to administer the program.
The City added 13 positions within the Department of Finance and another 11 positions at the Office of Administrative Tax Appeals to help process disputes and administer the surcharge.
That question remains one of the biggest unknowns.
While early discussions centered on a $5 million value threshold, state officials have indicated the City may rely on multiple data sources, including market sales, ownership patterns and modeling tools, instead of official property assessments alone.
That distinction carries significant consequences.
New York City's assessment system often values luxury condominiums and co-ops well below their market prices because assessments rely heavily on rental comparisons instead of recent sales.
That difference could complicate enforcement and increase appeals from owners who dispute whether their homes meet the threshold.
A fiscal analysis by the New York City Comptroller's Office warned that the City's ability to audit ownership and occupancy claims will largely determine whether projected revenue materializes.
"Lapses in DOF's auditing capacity and accuracy, would reduce revenues and multiply taxpayers' appeals and lawsuits," the report read.
It also noted that questions involving trusts, LLCs, leases and occupancy could significantly affect collections.
A Patch analysis of Zillow data found ZIP codes dominated by homes priced above $2 million recorded average annual price growth of 8.11 percent, more than double the 3.72 percent increase in entry-level markets and the 3.52 percentgain in mid-tier neighborhoods.

Citywide, home values increased 3.74 percent year over year.
Manhattan, despite containing many of the City's most expensive properties, posted just 0.85 percent annual price growth.
The data suggests much of the City's recent housing momentum has come from the high-end market now targeted by the surcharge.
Alongside the tax, the administration has advanced a package of government efficiency proposals that would go before voters in November.
The measures aim to reduce delays in permitting, speed construction approvals, streamline nonprofit contracting, accelerate street safety projects and establish a formal funding target for the City's rainy day reserve.
The administration estimates faster disposition of surplus properties alone could unlock more than $200 million in value.
The initiatives do not replace the revenue expected from the new second-home tax.
Economists say the broader fiscal impact remains uncertain.
Emily Eisner, acting chief economist at the Fiscal Policy Institute, called the surcharge a "significant advancement toward implementing progressive taxation," while cautioning that it will not solve the City's long-term budget challenges by itself.
She said New York City's revenue has failed to keep pace with economic growth over the past 15 years and argued the City's tax system has "grown detached from economic circumstances," suggesting broader reforms may still be necessary.
Real estate professionals expect the immediate effects to remain concentrated in the luxury market.
"So what's been driving real estate in New York for the past 12 to 18 months has been this kind of wealthy buyer," said Dolly Hertz of Engel & Völkers. "Basically Kathy Hochul will achieve stifling the very demand that's driving the market."
For now, property owners who receive notices are being asked to determine whether they qualify and, if necessary, provide documentation through the Department of Finance's new review process.
As the City moves from legislation to enforcement, attention will shift from whether New York could adopt a pied-à-terre tax to whether officials can accurately identify eligible properties, withstand expected appeals and collect the revenue lawmakers projected when they approved the measure.
