Summary
New York City Mayor Zohran Mamdani and Governor Kathy Hochul unveiled the state's first-ever pied-à-terre tax on April 23, 2026, fulfilling Mamdani's campaign pledge to tax wealthy residents. The tax targets luxury second homes valued above $5 million owned by individuals whose primary residence is outside New York State. The measure is expected to generate $500 million in annual revenue and could affect approximately 13,000 properties across the five boroughs.
To illustrate the tax's reach, Mamdani directly named Citadel CEO Ken Griffin and his $238 million penthouse at 220 Central Park South—which holds the distinction of being the most expensive residential property ever sold in the United States at the time of its 2019 closing. Mamdani filmed an announcement video outside the property, stating: "When I ran for mayor, I said I was going to tax the rich. Well, today, we're taxing the rich." The video subsequently accumulated tens of millions of views across social media platforms. Griffin acquired the 24,000-square-foot Midtown Manhattan property as a pied-à-terre while maintaining his primary residence and business operations in Miami, where he relocated Citadel's headquarters in 2022.
The public targeting of Griffin drew significant pushback from media and business circles. CNBC anchor Sara Eisen criticized the mayor's approach on social media, arguing that demonizing one of the city's major employers and investors risks backfiring economically. Eisen noted that Griffin employs thousands in NYC and is planning a substantial office tower development on Park Avenue with billions in planned investment and job creation. She added that Griffin's frequent presence in the city for business operations contradicts the characterization of the penthouse as merely a rarely-visited luxury asset, and highlighted that Miami is actively courting both Griffin and Citadel's capital investment.
The announcement has contributed to a broader business climate concern among NYC operators. Multiple restaurateurs and entrepreneurs have announced cancellations or redirections of expansion plans, citing discomfort with Mamdani's policy direction. This business reaction reflects a broader tension between the mayor's affordability and tax agenda and the city's competitive positioning as a global financial and commercial center.
