What happened to the lawsuit challenging the NYC pied-à-terre tax rollout?

A Brooklyn appellate court reversed a Staten Island judge's rulings and dismissed a lawsuit challenging New York City's pied-à-terre tax rollout, finding plaintiffs lacked standing because they had not shown they would actually owe the levy. The tax applies to single-family homes valued at $5 million or more and co-ops and condominiums worth at least $1 million, with surcharges set to appear on property tax bills due January 1. Two separate constitutional challenges, including one by Wilbur Ross and Steve Wynn, are scheduled for argument on December 1.

Key facts
  • A Brooklyn appellate court on Wednesday reversed a September ruling by Staten Island Justice Wayne Ozzi that had twice halted the NYC pied-à-terre tax rollout, finding the homeowner plaintiffs lacked standing.
  • The NYC pied-à-terre tax applies to single-family homes with market values of $5 million or more, and to co-ops and condominiums worth at least $1 million, according to the source text.
  • New York City officials plan to include the pied-à-terre surcharge on property tax bills due January 1.
  • In July, New York City sent 17,000 notices to owners of properties potentially eligible for the tax, and city officials said in late September they had granted 5,200 exemptions out of roughly 9,300 applications reviewed.
  • The pied-à-terre tax was championed by Mayor Zohran Mamdani and Governor Kathy Hochul and approved by state lawmakers in May.
  • Lawyer Randy Mastro, who brought the dismissed rollout lawsuit, said the constitutional challenge — with arguments scheduled for December 1 — would prove 'the ultimate day of reckoning' for the tax.

A Brooklyn appeals court on Wednesday dismissed a lawsuit challenging the rollout of New York City's pied-à-terre tax, ruling that the homeowner plaintiffs lacked standing to bring the complaint. The appellate panel reversed a September ruling from a Staten Island judge who had said the city improperly published a supplemental roll of property information and wrongly required homeowners to apply for exemptions.

The appeals judges found that the plaintiffs failed to demonstrate they would actually be subject to the tax. The court said the petitioners did not allege that any bad actors misused the information in the supplemental roll, or that the publication itself subjected them to any crime, harassment, or defined public ridicule. The publication of the supplemental roll did not cause the petitioners any concrete or definable injury, the court said, because the roll did not impose an obligation, deny a right or fix some legal relationship.

Staten Island Justice Wayne Ozzi had twice ordered the tax rollout halted, but his decisions were both times put on hold by the appellate court. The deadline to apply for exemptions from the tax was October 13. City officials said in late September that they had granted 5,200 exemptions out of roughly 9,300 applications reviewed.

The levy, championed by Mayor Zohran Mamdani and Governor Kathy Hochul, was approved by state lawmakers in May. It applies to single-family homes with market values of $5 million or more, and co-ops and condominiums worth at least $1 million. New York City officials plan to include the surcharge on property tax bills due January 1.

Mamdani hailed the decision, saying in a statement that the court rejected an attempt by the ultrawealthy to avoid paying their fair share. In July, the city sent 17,000 notices to owners of properties potentially eligible for the tax, inviting them to apply for exemptions. Ozzi had ruled that the city illegally shifted its own responsibility to correctly identify taxable properties.

The suit dismissed Wednesday challenged the city's implementation of the tax, but not the levy's legality. Two other suits against the state, including one by former US Commerce Secretary Wilbur Ross and casino tycoon Steve Wynn, are arguing the tax is unconstitutional because it discriminates against non-residents of the city. Arguments in those cases are scheduled for December 1.

Randy Mastro, the lawyer who brought the rollout lawsuit and is also behind one of the constitutional challenges, expressed disappointment that the court took the procedural offramp of standing to avoid addressing the merits of this case. Mastro predicted that the constitutional case would prove the ultimate day of reckoning for the tax. We remain confident we will prevail and put an end to this unconstitutional surcharge altogether, he said in a statement.

The Deployment Angle

Family Office Real Estate Daily Desk · our analysis, not the source's

Family offices with New York City residential holdings should inventory exposure immediately. The tax applies to single-family homes valued at $5 million or more and co-ops or condominiums valued at $1 million or more. The October 13 exemption deadline has passed, so any property that did not receive an approved exemption will face the surcharge on January 1 bills. Of the roughly 9,300 applications the city reviewed by late September, it granted 5,200 exemptions, a 56 percent approval rate.

The dismissal on standing grounds leaves the constitutional challenges as the only near-term procedural defence. Arguments in the Ross and Wynn cases are scheduled for December 1, less than a month before the billing date. Principals holding properties through non-resident entities should model the surcharge cost and compare it to the transaction cost of restructuring ownership to qualify for an exemption, assuming the constitutional cases fail.

For new acquisitions, underwrite the pied-à-terre tax as a permanent line item until the December 1 arguments resolve. The city sent 17,000 notices in July, so the potential scope is broad. If the constitutional challenges succeed, the tax disappears retroactively. If they fail, the levy becomes a recurring cost that compresses net yield on any property above the thresholds. Price that drag into any co-investment or direct purchase in the city, and avoid levering up to a threshold where the incremental tax makes the position uneconomic.
