We have another significant development regarding the constantly evolving New York City's pied-à-terre tax, and this latest ruling makes it increasingly important for cooperative boards and property managers to begin preparing for the financial implications.

Yesterday, the Appellate Division, Second Department, issued a decision in Matter of O'Brien v. City of New York, dismissing the lawsuit and reversing a September 29 Staten Island lower-court ruling that had temporarily halted the City's implementation of the tax and ordered the City to cancel or redo the initial notices sent out.

What Does This Ruling Mean?

The appellate court dismissed the homeowners' lawsuit, finding that the plaintiffs lacked legal standing to challenge the City's initial rollout procedures.

Specifically, the court determined that receiving an initial tax determination notice or being included on the City's published property list did not, by itself, establish the type of legal injury necessary to bring the lawsuit.

Importantly, the court also found that the City's initial determination notices satisfied the applicable legal requirements. As a result of the Court Decision, the City can move forward with implementing the pied-à-terre surcharge without having to reissue the initial notices challenged in this lawsuit.

However, this does not mean that all legal challenges to the tax have been resolved. This particular lawsuit concerned the City's implementation procedures, not the constitutionality of the tax itself. Separate constitutional challenges remain pending, with arguments reportedly scheduled for December 1, 2026 in  another case. For now, cooperative boards should not assume that these pending challenges will delay their tax obligations.

Why This Is Especially Important for Co-op Boards

As we have previously advised, cooperative corporations face a unique concern under the City's existing real estate tax billing structure. Because the cooperative owns the building and is responsible for paying its real estate taxes, a pied-à-terre surcharge attributable to an individual shareholder will likely ultimately appear on the cooperative's property tax bill.

This creates a significant issue: How does the Co-op recover that expense from the shareholder responsible for triggering the tax?

In many cases, a Co-op's existing Proprietary Lease or Occupancy Agreement may not provide sufficient authority to charge the surcharge directly back to the individual shareholder without an amendment. With the next applicable tax payment deadline approaching on January 1, 2027, boards should be addressing this issue now rather than waiting until the surcharge appears on the building's tax bill.

What Should Boards and Property Managers Be Doing Right Now?

We strongly encourage cooperative boards and property managers to take the following steps:

1.  Review your Proprietary Lease or Occupancy Agreement. Determine whether the governing documents provide sufficient authority to assess an individual shareholder for a pied-à-terre surcharge attributable to their unit.

2.  Consider whether an amendment is necessary. If the existing documents do not provide the required authority, the cooperative should consult counsel about adopting an appropriate amendment before attempting to collect the surcharge.

3.  Identify potentially affected shareholders and review tax notices. Work with management to determine whether any units may be subject to the surcharge and carefully review any notices or determinations received from the Department of Finance.

4.  Plan ahead for collection and payment. Boards should consult with their managing agents and legal counsel regarding how any applicable surcharge will be collected from shareholders, while ensuring the cooperative is prepared to meet its own tax payment obligations.

5.  Continue monitoring pending litigation. Although the latest decision allows implementation to move forward, additional legal challenges remain unresolved. Boards should not rely on a possible future court ruling as a reason to delay their preparations.

Our Recommendation: Do Not Wait

The November 4 ruling is an important development because it removes a significant obstacle to the City's implementation of the pied-à-terre tax. While uncertainty remains regarding the ongoing constitutional challenges, Co-op boards should be preparing now for the possibility that these charges will need to be paid and recovered from affected shareholders in the coming weeks.

Schneider Buchel LLP is continuing to monitor these developments closely. If your cooperative has not yet reviewed its Proprietary Lease or Occupancy Agreement to determine whether it has the authority to charge back pied-à-terre taxes, we strongly encourage you to contact our office.

Our attorneys can review your governing documents, advise whether an amendment may be necessary, and help your board establish a legally appropriate approach to addressing these charges before the upcoming tax payment deadline. We will continue to provide updates as additional court decisions and guidance become available.
