Mayor Mamdani Unveils NYC Pied-à-Terre Tax
On April 15, Mayor Zohran Mamdani released a one-minute video outside 220 Central Park South, the building that houses hedge-fund CEO Ken Griffin’s $238 million penthouse. The mayor announced an annual levy on luxury secondary residences valued above $5 million when the owners do not maintain a full-time New York residence. The proposal targets one- to three-family homes, condos and co-ops.
Fiscal Context and Policy History
New York City faces a projected $5.4 billion budget gap for the current fiscal year, with officials estimating a $12 billion shortfall over two years. Governor Kathy Hochul has voiced support for the tax, but state legislative approval remains pending. Similar “pied-à-terre” proposals have stalled in Albany for several years.
Principal Actors
- Zohran Mamdani – Mayor of New York City.
- Kathy Hochul – Governor of New York State.
- Ken Griffin – Founder and CEO of Citadel, owner of the featured penthouse.
- Gerald Beeson – Citadel’s chief operating officer.
- Bill Ackman – CEO of Pershing Square, public defender of Griffin.
- Steven Fulop – Head of the Partnership for New York City.
- Nathan Goldman – Professor, North Carolina State University, tax-policy expert.
- Jonathan Miller – CEO, Miller Samuel appraisal firm.
- Robert Pollack – Senior partner, Marcus & Pollack LLP.
Financial Projections and Economic Data
The tax would apply to properties exceeding $5 million; city officials estimate it could generate at least $500 million annually. Approximately 4,146 Manhattan units sold for $5 million or more in the past five years, with about 70 % classified as second homes. Griffin’s penthouse is assessed at $6.99 million (city assessment) versus a market value of $15.5 million. Citadel projects its Midtown redevelopment at 350 Park Avenue to cost over $6 billion, creating 6,000 construction jobs and 15,000 permanent positions.
Official Statements & Responses
Mayor Mamdani framed the levy as a correction of “a fundamentally unfair system,” directing revenue to free childcare, street cleaning and neighborhood safety. Governor Hochul endorsed the measure as a tool to address the budget gap. Citadel’s internal memo, authored by Beeson, warned the mayor’s rhetoric could jeopardize the Midtown project and highlighted the firm’s $2.3 billion contribution in city and state taxes over five years, as well as Griffin’s $650 million in charitable donations. Ackman posted on X that non-resident owners “drive NYC’s economy” and should be praised for their investments. Fulop urged an exemption for job creators, arguing that halting the Citadel project would cost the city billions in tax revenue and employment.
Criticism & Opposition
Business leaders, including Ackman and Fulop, argue the tax may deter high-value development and prompt an exodus of wealth to lower-tax states. Tax scholars such as Goldman warn that owners of properties valued between $5 million and $6 million will likely pursue litigation, citing the subjectivity of valuation. Miller notes that the city’s assessment methodology, based on rental equivalents, often yields values far below market prices, creating uncertainty for taxpayers.
Conflicting Reports & Gaps
Sources differ on whether the levy will use assessment values or market values, a distinction that could alter liability dramatically. The exact rate structure remains unclear; a 2019 draft suggested graduated rates (0.5 % above $5 million, 1.5 % above $10 million, 4 % above $25 million), but the current proposal has not confirmed this. Definitions of “primary residence” are also unsettled, leaving open the possibility that owners could reclassify properties to avoid the tax.
Verbatim Quotes

- “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,” — Gerald Beeson, COO, Citadel

Upcoming Developments
The proposal now awaits passage by the New York State Senate and Assembly. Legal challenges are anticipated as owners assess their exposure under the chosen valuation method. Citadel’s decision on the 350 Park Avenue redevelopment will likely be influenced by the tax’s final design and any concessions granted to large-scale developers.
