New York Extends Pied-à-Terre Tax Exemption Deadline After Mistaken Notices

Extended Exemption Deadline Amid Notification Mistake
City attorneys filed court documents confirming that the deadline for owners to apply for an exemption from the city’s pied-à-terre surcharge is now October 6. The deadline had already been moved once, from a late-August target to September 18, after widespread backlash.
The Department of Finance (DOF) originally mailed 17,000 notices warning property owners that they could face the tax unless they proved the residence was primary. Court filings reveal that at least 1,210 of those letters were sent to addresses that are actually primary homes. To correct the error, DOF will issue another 10,800 letters by August 31, directing owners—including 6,400 properties owned by entities or trusts and 4,400 addresses whose primary-residence status could not be verified—to submit proof or risk the surcharge.
As of late August, almost 11,000 exemption applications had been started, with just over 5,500 completed and roughly 2,900 exemptions granted. The five homeowners who sued the city have already received approved exemptions.
Official Statements & Responses
DOF Commissioner Richard Lee explained that the city could not appear before a City Council oversight committee because of “sensitive active litigation,” according to his written testimony.
Criticism & Opposition
Plaintiffs’ attorney Randy Mastro, who represented the homeowners in the Staten Island Supreme Court suit, described the city’s actions as a “massive screw-up,” arguing that the administration shifted the burden of proof onto thousands of residents who must now demonstrate they actually live in their homes. The plaintiffs contend that the initial list of over 900,000 addresses was arbitrarily compiled, forcing owners to prove a negative.
What’s Next
Oral arguments in the exemption lawsuit are scheduled for August 31. The court will consider whether the city’s rollout and the extended deadline comply with legal standards and whether further relief is warranted for affected homeowners.
