- • NYC Mayor Zohran Mamdani publicly named Citadel CEO Ken Griffin's $238 million penthouse at 220 Central Park South (purchased in 2019 as the most expensive U.S. home sale at closing) as a primary example of properties targeted by the tax in an official announcement video released on Tax Day 2026.
- • Citadel responded through Chief Operating Officer Gerald Beeson with an internal memo objecting to the tax characterization, claiming Citadel principals and employees paid nearly $2.3 billion in combined city and state taxes over the preceding five years, arguing Griffin is already carrying his "fair share of burdens."
- • The tax applies to wealthy individuals with primary residences outside New York City or state, including multiple billionaires such as Jeff Bezos and Donald Trump, and represents a key campaign promise fulfillment by Mayor Mamdani to address the city's budget gap.
Summary
On Tax Day 2026, New York City Mayor Zohran Mamdani and Governor Kathy Hochul jointly announced the state's first-ever pied-à-terre tax, a surcharge on luxury second homes valued above $5 million owned by individuals whose primary residence lies outside New York City. The measure is projected to generate $500 million in annual revenue and could affect as many as 13,000 properties across the five boroughs. Mamdani framed the announcement as fulfillment of a campaign promise, stating: "When I ran for mayor, I said I was going to tax the rich. Well, today, we're taxing the rich."
To underscore the policy's intent, Mamdani's office specifically flagged Citadel CEO Ken Griffin's penthouse at 220 Central Park South as an exemplar of the tax's target properties. Griffin purchased the 24,000-square-foot Midtown residence for $238 million in 2019, making it the most expensive home ever sold in the United States at that time. According to reporting, Griffin uses the property as "a place to stay when he's in town," despite maintaining his primary residence and Citadel's headquarters in Miami (relocated from Chicago in 2022) and operating an extensive property portfolio spanning Saint-Tropez, London, Hawaii, and the Hamptons.
Citadel responded swiftly, with Chief Operating Officer Gerald Beeson issuing an internal memo objecting to the mayor's characterization of Griffin as insufficiently tax-burdened. "It is shameful that he used Ken's name as the example of those who supposedly aren't carrying their fair share of the burdens associated with New York City's often costly and wasteful spending," Beeson stated. The memo asserted that Citadel's principals and team members collectively paid nearly $2.3 billion in city and state taxes over the preceding five years, directly challenging Mamdani's framing.
The pied-à-terre tax would apply broadly to wealthy property owners with primary residences outside the state or city, as well as investment properties, and would operate independently of existing property tax obligations. While the state has not disclosed specific implementation details regarding property valuation methodologies or final tax rates, the measure targets numerous high-profile billionaires including Jeff Bezos and Donald Trump. The tax represents part of Governor Hochul's broader state budget proposal and Mamdani's effort to close New York City's budget deficit, positioning wealth-focused taxation as a cornerstone policy objective.
