We Did the Math on Ken Griffin's Pied-À-Terre Tax Bill

Why It Matters

The tax marks a shift toward taxing luxury secondary residences, generating new city revenue and forcing ultra‑wealthy owners to reassess their real‑estate strategies.

Key Takeaways

• Griffin owes $1.3‑$1.4 million in NYC pied‑à‑terre tax.
• Tax applies to ~10,000 NYC secondary residences.
• Rates range 0.8%‑1.3% for condos, up to 6.5% for co‑ops.
• Other billionaires like Bezos, Schultz, Trump also face the levy.

Pulse Analysis

The city’s pied‑à‑terre tax, approved by the New York City Council and signed into law by Mayor Zohran Mamdani, targets luxury secondary residences that sit vacant for most of the year. Designed to address the city’s affordable‑housing deficit, the levy imposes a graduated rate—up to 6.5 percent on assessed values for condominiums and co‑ops, and 0.8 to 1.3 percent for single‑family homes—once a new assessment system is in place. By focusing on the roughly 10,000 high‑value units that escape regular occupancy, officials hope to capture untapped revenue without burdening average renters.

Ken Griffin, the Citadel founder with an estimated net worth of $48.3 billion, exemplifies the tax’s reach. He holds three New York properties: a record‑setting $240 million penthouse on Central Park South, now valued at $15.55 million for tax purposes, and two Upper East Side co‑op shares worth about $6.2 million combined. Applying the current 6.5 percent rate to the co‑op holdings and the lower condo rates to the penthouse translates into a bill of $1.3‑$1.4 million for the 2025‑26 fiscal year. Griffin’s opposition underscores the tension between wealth preservation and municipal fiscal needs.

The levy could reshape the behavior of ultra‑wealthy owners nationwide. As other billionaires—Jeff Bezos, former Starbucks CEO Howard Schultz, and former President Donald Trump—face similar charges, some may consider relocating or converting properties to primary residences to avoid the surcharge. For the city, the tax promises a new revenue stream that can be directed toward affordable‑housing initiatives and infrastructure upgrades, while also signaling a political willingness to tax privilege. However, critics warn that inflated assessments and a nascent valuation system could lead to legal challenges, prompting the administration to refine the methodology over the next two years.
