Mayor Zohran Mamdani’s administration has published a searchable database of Big Apple properties that could fall under the state’s new pied-à-terre tax, effectively doxxing thousands of wealthy New Yorkers.
The city’s Department of Finance uploaded the comprehensive list – which purports to cover all unoccupied, non-primary residences in the five boroughs worth north of $1 million – including the full names and addresses of every property owner.
The move follows a widely panned X post by the mayor in which he put wealthy residents on notice to “check your mailbox when you’re back in the five boroughs, because you’ve got mail,” a warning that notification letters were on their way.
“The best city in the world deserves the best parks, libraries, and schools in the world. That’s only possible when we all pay our fair share,” Mamdani wrote Thursday.
The socialist darling has long touted the policy enacted by Gov. Kathy Hochul and Albany Democrats to tax second homes in the city – though critics have warned it could cause property values to plummet.
Mamdani threatened to raise city property taxes by a staggering 9.5% in February unless he was allowed to “tax the rich” to cover a $12 billion budget gap that was later revised down to $5.4 billion.
City Hall estimates the pied-à-terre tax would yield $500 million per year for the Big Apple’s budget.
