NY Court Blocks NYC's New Tax on High-Value Secondary Homes
On August 10, 2026, NY Supreme Court halted NYC’s new tax on luxury secondary residences.
Why it matters: In-house counsel and legal teams at real estate firms must track this ruling as it affects enforcement of a major municipal tax on high-value non-primary homes, potentially altering compliance requirements and litigation risks for property owners.
- Judge Wayne Ozzi granted a temporary restraining order on August 10, 2026, blocking NYC’s pied-à-terre tax enforcement.
- The tax targets secondary residential properties valued above $5 million owned by non-primary residents in NYC.
- The city is barred from publicly posting the Supplemental Roll listing taxable properties, delaying implementation.
- The tax was slated to begin under Mayor Mamdani’s administration in August 2026 to generate additional revenue from luxury homes.
On August 10, 2026, New York Supreme Court Judge Wayne Ozzi issued a temporary restraining order that temporarily blocks New York City’s new pied-à-terre tax.
This tax was designed to impose a surcharge on high-value residential properties owned by non-primary residents, specifically targeting secondary homes in New York City valued at over $5 million. It aimed to raise municipal revenue by taxing luxury properties often used occasionally rather than as primary residences.
The court order prevents the city from proceeding with key enforcement actions, including the public posting of the Supplemental Roll—a detailed list naming properties subject to the tax. This pause delays the city’s planned rollout scheduled for August 2026 under Mayor Mamdani’s administration.
Legal professionals should note this ruling may set important precedents for challenges to municipal taxation measures affecting property owners. This decision highlights the scrutiny courts can apply to new tax schemes, especially those affecting affluent or non-resident owners.
While full legal reasoning behind the restraining order has not been publicly disclosed, the decision signals challenges ahead for the city in defending the tax. It also raises compliance questions for legal teams advising clients with luxury real estate holdings in NYC.
Further updates will be important as NYC considers how to proceed, whether through legal appeals or by modifying the tax structure.
By the numbers:
- August 10, 2026 — date of the court's temporary restraining order
- $5 million — minimum property value threshold for pied-à-terre tax applicability
- August 2026 — originally scheduled tax effective date
What's next: The city is expected to file further legal motions to defend or revise the tax; stakeholders await court decisions that will clarify enforcement prospects.
