Pied-a-Terre Tax Ruling and Appeal: If You Hold a Notice

Facts checked October 9, 2026.

On September 29, 2026, Justice Wayne Ozzi of Richmond County Supreme Court ordered New York City to cancel the roughly 17,000 pied-a-terre tax notices it had mailed, and the city appealed the same night, which puts the order on hold. If you are holding one of those notices, the practical answer is short: the Department of Finance still lists October 13, 2026 as the exemption deadline for homes, condos and co-op units, and the surcharge itself is still law.

My advice is the same one I gave in the first week after the ruling: treat the deadline as live and file the exemption anyway. A judge's order about how the city mailed notices does not tell the city what your apartment is, and it does not tell you what your proof shows. Filing costs nothing and protects you whichever side wins the stay fight. The full ruling is in my earlier report on the decision; this page is for the person who has the letter in hand.

What the court decided, in plain terms

The case is O'Brien v. City of New York, filed August 7, 2026 by three homeowners. The judge held that the city's process violated the homeowners' due process rights, meaning the city put the burden on owners to prove they live in their homes instead of using data it already held. He ordered the notices cancelled, ordered the public roll replaced by a list of properties actually subject to the surcharge, and ordered new notices only after an individual determination for each property.

Why the appeal matters more than the headline

When the city appeals, a stay (an automatic pause on the order) takes effect. The city said it would keep carrying out the surcharge while the appeal runs. So the cancelled notices are not cancelled in practice for now. The plaintiffs read it differently: REBNY told members the plaintiffs say the order stays in force unless the city obtains a stay from the Appellate Division. The Department of Finance has not said in writing that the deadline no longer applies, and its page still shows October 13.

That last line deserves care. The homeowners' lawyer said the city told the court it would not invoice before November 15, 2026 or collect before January 1, 2027. That is one side's account of a court statement. I am passing it along as reported, not as the city's published position.

What I would do if the notice is sitting on your desk

• File the exemption online at nyc.gov/npsurcharge with the PIN on the notice, even if you think the notice was a mistake. About 35% of the notices went to primary residences, according to The City Reporter, which is the strongest argument that the mailing was wrong and the weakest reason to skip the filing.
• Upload the tax return or license for every occupant, plus tenant or entity papers if they apply. The filing guide lists each document.
• Save the confirmation. If the courts cancel the old notices and the city restarts with individual determinations, a timestamped filing is the best evidence you were responsive.
• Do not let the lawsuit drive a sale, a lease or a purchase decision until your attorney has read it against your facts.

What would change this

Three things move the picture: whether the Appellate Division rules on the stay, whether the two Suffolk County suits go to the same judge, and what the Department of Finance publishes on or before the deadline. If any of them lands, the Department of Finance page is the first place the new date will show up.

If you own a condo or co-op near the $1,000,000 valuation line, the ruling does not move that line either. See how the $1,000,000 cliff works and the pied-a-terre tax hub for the building-by-building roll.

This is general information, not legal or tax advice. Confirm your own filing with a New York real estate attorney or your CPA. Litigation is moving and some details may change after October 9, 2026.
