Here is the number that should reframe how you think about this: 3,655.
That is how many pied-à-terre tax exemptions New York City had actually approved as of Aug. 28 — against a supplemental tax roll that named more than 900,000 properties. If you own, broker, or lend against NYC residential product above $5 million, that gap is the entire story. Not the tax. The administration of the tax.
On Monday, that gap walked into a Staten Island courtroom. What happens next will tell you whether a tax that is almost certainly here to stay arrives on schedule or arrives a year late — and that timing difference is worth real money in your underwriting.
Let’s get into it.
What Actually Happened in Court
Lawyers for Mayor Zohran Mamdani’s administration faced off against homeowners’ attorneys before Judge Wayne Ozzi over the rollout of the surcharge on homes valued above $5 million.
This is the same judge who issued a temporary restraining order earlier this month that briefly halted implementation. That order was later stayed pending the administration’s appeal — so the tax is technically moving, but under a cloud.
Ozzi signaled he remains open to the arguments that produced his original TRO. He appeared receptive to the claim that homeowners were wrongly included in the published list and sent eligibility letters in error. But he pressed on the question that decides the case: were they actually harmed?
That is the whole ballgame. Not “was this messy” — everyone concedes it was messy. The question is whether messy is legally actionable.
The Numbers Nobody Is Saying Out Loud
Former Deputy Mayor Randy Mastro, representing the homeowners, built his case not on the tax itself but on the notices — which he memorably called “nasty-grams.”
“That’s over 6,750 people who for sure never should have gotten those threatening mail notices mailed in July. That’s 40 percent of the mail notices they sent. They didn’t do what the statute required and now they’re backpedaling to try to plug the holes.” — Randy Mastro
Run that math backward, because it is more useful than the quote. If 6,750 erroneous notices represent 40 percent of the mail sent, the city issued roughly 16,875 notices total. Against a supplemental roll of 900,000+ properties.
Now layer in the city’s own reported numbers as of Aug. 28:
| Stage | Count | Conversion |
|---|---|---|
| Exemption applications initiated | 10,871 | — |
| Applications completed | 5,874 | 54% of initiated |
| Exemptions approved | 3,655 | 62% of completed |
Two things jump out at any operator.
First, the abandonment rate. Nearly half of everyone who started an exemption application never finished it. That is not apathy. That is a process friction problem — and in a compliance regime, friction that stops people mid-application is a design defect, not a user failure.
Second, the approval rate is high. Sixty-two percent of completed applications were approved. When most people who finish the process turn out to be exempt, it is fair to ask why they were on the list at all.
The Judge’s Question Was the Sharpest Thing Said All Day
Ozzi turned to the city’s attorney, Steven Banks, and asked the question that lands hardest:
“Did you expect when the supplemental roll was published, that it covered 900,000 properties, or just that a small portion of that would be covered properties? […] What did you expect the public to think about that?”
That is a judge telling you he understands the difference between a tax roll and a target list — and that publishing the first while implying the second has consequences.
Banks argued for dismissal on clean grounds: the administration has issued no final tax determinations, so no homeowner has been harmed by a letter or a listing. He also emphasized the case was not filed as a class action, which sharply limits the relief available.
He is not wrong on the law. The petitioners — including Legacy Real Estate’s Kenneth Fishel and the wife and father of Council member Frank Morano — will, by the city’s own admission, not ultimately owe the tax. Which is Mastro’s point and Banks’ defense simultaneously.
The Political Layer Matters to Your Timeline
Here is the detail that should worry anyone modeling implementation risk.
DOF Commissioner Richard Lee did not appear at the City Council’s oversight hearing on the rollout. In written testimony, he cited the active litigation, noting he had offered to testify after the court date — and that the Council declined to move its Aug. 18 hearing.
So: the agency running the rollout skipped legislative oversight, citing a lawsuit, while defending the rollout in court. Whatever you think of the merits, that is an administration fighting on two fronts with a hard deadline.
And the deadline has already moved. Twice. The final day to contest DOF’s eligibility determinations now sits at Oct. 6.
What This Actually Means for Operators
Let me be direct about the read, because the headlines are getting this wrong.
The tax is not in danger. This suit does not challenge the statute’s constitutionality. Mastro said so explicitly — his clients are not trying to wipe out the tax. They are attacking the rollout. A win here does not repeal anything.
But the calendar is in danger. The relief sought — voiding the original letters, voiding the supplementary roll, restarting the initial steps — would functionally reset the clock. Banks warned that granting it would leave homeowners with less time to appeal, not more. That is a real argument, and it cuts against the petitioners.
And Ozzi knows it. He closed by saying he would prioritize a written determination specifically to avoid adding delay. Read that as a judge who intends to rule fast, whichever way he rules.
Three practical implications:
- Underwrite the tax as permanent. Any $5M+ NYC residential asset should carry the surcharge in the hold-period model. Betting on repeal is not a strategy.
- Do not underwrite the timing as certain. A rollout reset is a live possibility. If you are pricing a 2026 disposition around exemption clarity, build in slippage.
- Fix your own eligibility paperwork now. Oct. 6 is the contest deadline, and roughly half of applicants who start never finish. Do not become that statistic on an asset you actually care about.
The Real Lesson Here
“Do the homework, do the hard work on the front end, determine who owes the tax and only go to those people.” — Randy Mastro
Strip away the courtroom theater and that is a process critique, not a policy one. The city chose breadth over precision — cast the widest net, sort it out on the back end, push the burden of proof onto property owners.
That is a defensible administrative choice under time pressure. It is also exactly the choice that generates 6,750 wrong letters, a 46 percent application abandonment rate, two deadline extensions, and a judge asking what you expected the public to think.
Every operator has made this trade. Ship fast and clean up, or build it right and ship late. New York City just found out what the cleanup costs when the counterparty has Randy Mastro on retainer.
Watch for Ozzi’s written ruling. It is coming quickly, and it sets the implementation calendar for every $5M+ residential asset in this city.
What is your read — is a messy rollout of a valid tax a legal problem, or just a bad look? I would genuinely like to hear how you are modeling this.
