New York City Scales Back Pied-à-Terre Tax Enforcement
8/29/2026, 4:59:43 AM
Revised Pied-à-Terre Tax Rollout
Mayor Zohran Mamdani announced that the city will send new “you may be subject to” letters to a reduced pool of about 10,800 owners, down from the roughly 17,000-18,000 letters previously mailed. The deadline for owners to prove full-time residency has been extended to early October. The change follows criticism that the original rollout relied on outdated 2025 income-tax filings.
Legal Challenge and Opposition
Attorney Randy Mastro is suing the city on behalf of several homeowners who claim they are full-time residents. He argues the city’s reliance on incomplete tax data is a “dog-ate-my-homework” excuse and that the administration’s handling of the rollout was fundamentally flawed. “This is tantamount to an admission that the Mamdani administration massively screwed up and that we were right all along,” — Randy Mastro “They never bothered to get 2025 until after we filed this lawsuit. And guess how quickly they got it? We filed on August 7. They had the state data on who paid 2025 taxes or applied for extensions by August 12, days later,” — Randy Mastro
Data, Timeline, and Scope
- “So by my last count, I think we sent out less than 20,000, 'you may be subject to' letters, I think it was about [17,000] or 18,000. And at the time that we sent those out, we did not have access to the 2025 income tax filings,” — Zohran Mamdani, york city mayor
- Legal filing: The lawsuit was filed on August 7. “They never bothered to get 2025 until after we filed this lawsuit. And guess how quickly they got it? We filed on August 7. They had the state data on who paid 2025 taxes or applied for extensions by August 12, days later,” — Randy Mastro
- State data acquisition: City officials obtained 2025 tax-payment data by August 12. “They never bothered to get 2025 until after we filed this lawsuit. And guess how quickly they got it? We filed on August 7. They had the state data on who paid 2025 taxes or applied for extensions by August 12, days later,” — Randy Mastro
- Current target pool: Approximately 10,800 owners now face possible surcharge assessments for second homes valued over $5 million or co-ops/condos over $1 million.
Official Response
Mayor Mamdani emphasized that the city’s priority is to simplify the process for affected residents. “Our job is to make this process as easy as possible,” — Zohran Mamdani, york city mayor He did not concede that the rollout was mishandled, but acknowledged the need to adjust the enforcement timeline and pool size.
Outlook
The lawsuit remains active, and Mastro indicated he will continue efforts to protect homeowners who may still be targeted. The city has not indicated that the legal challenge will be withdrawn despite the revised enforcement parameters.
