A New York appeals court has dismissed a homeowners’ lawsuit challenging the city’s pied-à-terre tax on high-value second homes, ruling that the plaintiffs lacked legal standing, while separate legal challenges over the tax’s constitutionality and revenue limits remain pending.

A New York state appeals court has overturned a lower court ruling that had ordered New York City to redo the rollout of a tax on high-end second homes on 4 November 2026 to dismiss the homeowners’ lawsuit because the plaintiffs lacked legal standing.

The decision reverses a 29 September 2026 ruling by a Staten Island judge, who had found the city mishandled the process and ordered it to start over.

What the tax covers

The surcharge, known as the pied-à-terre tax, was approved by the state Legislature in May 2026 and will apply from 1 July 2026 through 30 June 2031. It applies to qualifying second homes valued at USD 5 million or more for one- to three-family properties, and at USD 1 million or more for condos and co-ops. The surcharge does not apply if the owner rents the home or if a relative lives there most of the time.

The city’s Department of Finance sent initial determination notices to about 17,000 property owners in July 2026. The city expects the tax to bring in roughly USD 500 million a year.

In April 2026, New York Governor Kathy Hochul and Mayor Zohran Mamdani announced a joint proposal to introduce a new tax on second homes valued at more than USD 5 million.

Court finds no standing

The appeals court said that receiving a tax notice or appearing on the city’s property valuation list did not cause enough harm to support a lawsuit. It also rejected claims that the process caused harm through privacy concerns or the cost of seeking exemptions.

Mayor Zohran Mamdani welcomed the ruling. He said the city’s wealthiest property owners had tried every legal route to avoid paying more.

Challenges continue

Randy Mastro, the attorney for the homeowners, criticised the court’s dismissal of the case without reviewing its merits, while two other lawsuits challenging the tax remain pending. They argue that the tax exceeds state limits on real estate tax revenue and unconstitutionally targets out-of-state owners, with a ruling on the constitutional challenge expected in December 2026.
