City Extends Deadline for Pied-à-Terre Tax Exemptions Following Notification Confusion

New York City officials have granted a four-week extension for property owners to submit applications for exemptions from the city’s new pied-à-terre surcharge. The new deadline is September 18, 2026, according to an announcement from Mayor Zohran Mamdani and Department of Finance Commissioner Richard Lee.

The surcharge, which was approved in May, targets one- to three-family homes, condominiums, and co-ops valued at $5 million or more that are not used as the owner’s primary residence. The tax is intended to generate at least $500 million in annual revenue to address the city's budget gap.

Since the city began issuing notices to potentially affected homeowners late last month, the rollout has faced significant criticism. Numerous residents reported receiving letters despite living in their properties full-time. Among those who publicly noted receiving the notices were long-term residents and local officials, including Council Member Gale Brewer.

Mayor Mamdani attributed the confusion to a misunderstanding of the city's property tax rolls, noting that the notices were sent to a broad list of non-rental residential properties, not exclusively to those subject to the tax. Approximately 17,000 homeowners have received the letters to date, though the majority of properties on the broader tax list fall below the $5 million valuation threshold.

“There has been both a willful and an unintentional conflation of both the property tax roll and these letters,” Mamdani stated during a recent press conference.

To mitigate further issues, the Department of Finance has expanded its outreach efforts. The city is working with co-op and condominium boards, property managers, and community centers to clarify the exemption process. Officials are also reaching out directly to those who received notices to provide guidance on how to prove primary residency or otherwise demonstrate that they are not subject to the surcharge.

Commissioner Lee encouraged those who received a letter to utilize the additional time to seek assistance. Homeowners requiring help with the application or appeals process are directed to contact the Department of Finance via 311 or the agency's official website.
