New York City Mayor Zohran Mamdani announced a new wealth tax on luxury second homes valued over $5 million [1].
The proposal seeks to generate municipal revenue and improve housing affordability by targeting ultra-wealthy owners of vacant properties. If implemented, the "pied-à-terre" tax is expected to raise at least $500 million per year [2].
On April 15, 2026, the mayor framed the initiative as a direct effort to increase funding through the wealth of the city's most affluent residents. "We're taxing the rich," Mamdani said [2].
Billionaire investor Bill Ackman responded to the announcement on April 15, 2026 [3]. While Ackman defended the presence of high-value investments in the city, he cautioned the administration against aggressive tactics that might alienate wealthy residents. "Don't scare away the billionaires," Ackman said [3].
Ackman mentioned hedge-fund manager Ken Griffin, whose New York City penthouse is valued at $238 million [1]. Ackman praised the investment and the impact of such high-value properties on the city's economy. "We should be applauding Ken," Ackman said [3].
The proposal comes as the city administration and Governor Kathy Hochul navigate the balance between increasing public revenue and maintaining New York City's status as a global hub for finance, and luxury real estate [1].
“"We're taxing the rich."”
The proposal highlights a growing tension in New York City between progressive revenue goals and the desire to retain ultra-high-net-worth individuals. By targeting 'pied-à-terre' properties, the administration is attempting to discourage the use of luxury real estate as dormant capital, though critics like Ackman argue that such measures could trigger capital flight among the city's most influential investors.
