The temporary block creates uncertainty for the city's budget planning and the real estate market, potentially delaying expected revenue from the tax. Property owners and investors may see reduced immediate tax liability, but the appeal and ongoing litigation could prolong uncertainty.
On August 10, 2026, United States — Supreme Court of the United States Justice Wayne Ozzi issued a temporary restraining order blocking the rollout of United States — New York City Mayor Zohran Mamdani's pied-a-terre tax. The order requires the city to remove a tax roll covering approximately 960,000 residential properties and bars further enforcement of notices sent to about 17,000 homeowners. The lawsuit, filed by three homeowners represented by Randy Mastro, argues the city improperly shifted the burden of proving primary residence onto property owners. The city plans to appeal, which will automatically stay the order. The tax, signed into law by Governor Kathy Hochul in May, targets second homes valued at $5 million or more and condos/co-ops valued at $1 million or more, and is projected to raise $500 million annually. The next hearing is scheduled for August 31.
