New York City Pied-à-Terre Tax – Implementation and Key Response Deadlines

Tue 11 August 2026 News & Press

New York City Pied-à-Tere Tax Temporarily Blocked by Judge

As discussed below under “Legal Challenge,” the Richmond County Supreme Court granted, on August 10, 2026, the property owners’ request for a temporary restraining order, temporarily blocking the City from taking further steps to enforce the surcharge pending further proceedings. The court scheduled the matter for hearing on August 31, 2026.

The eventual outcome in this litigation is uncertain. Accordingly, property owners should take steps to understand whether the tax may apply to their specific situation and be prepared to make an appropriate filing per the information set forth below, as needed.

Implementation

Our previous alert memorandum dated April 23, 2026, discussed the proposed New York City Pied-à-Terre and its potential impact on owners of luxury secondary residences. On April 15, 2026, the Mayor’s Office announced implementation of the surcharge in its news release.

Following enactment of the surcharge, New York City began implementation. On July 24, 2026, the Department of Finance (“DOF”) began notifying property owners who may be subject to the surcharge and launched a dedicated webpage providing guidance regarding eligibility, exemptions, and the submission of supporting documentation. As discussed above, further enforcement of the surcharge is currently subject to the temporary restraining order issued on August 10, 2026.

The New York City Department of Finance (“DOF”) has also created a dedicated webpage explaining the surcharge, available exemptions, required documentation, and response procedures.

Property owners may use this eligibility guide to find out how to respond to any letter received from the DOF, including which documents are needed. Mclaughlin & Stern is available to assist clients in evaluating eligibility, preparing exemption submissions, and addressing questions regarding the surcharge.

For properties determined to be subject to the surcharge, bills are expected to be issued in November 2026, with the surcharge due on January 1, 2027.

Legal Challenge

On August 10, 2026, the Richmond County Supreme Court granted the property owners’ request for a temporary restraining order, temporarily blocking the City from taking further steps to enforce the surcharge pending further proceedings. The court scheduled the matter for hearing on August 31, 2026.

The temporary restraining order arises from a lawsuit filed on August 7, 2026, by three New York City property owners challenging the City’s implementation of the surcharge. The property owners allege that the City failed to follow the legally required process by publishing the supplemental market value roll, a public list of residential properties identified based on their market value, and sending notices to approximately 17,000 property owners before determining which properties were non-primary residences potentially subject to the surcharge.

The property owners seek to invalidate the supplemental market value roll and mailed notices.

Reason for Receiving Notices

The DOF has begun mailing notices to owners of residential properties that appear to meet the applicable valuation thresholds for the surcharge. Importantly, these notices are based on the City’s property records and do not necessarily reflect whether a property ultimately qualifies for an exemption. Accordingly, receipt of a notice should not be interpreted as a final determination that the surcharge applies.

Instead, the notice begins the administrative review process and provides the property owner with an opportunity to demonstrate that an exemption is available.

Key Response Deadlines for Exemption Applications (Recently Extended)

Applicable to everyone who received a notice from the Department of Finance:

  • Residential homes and condominiums: Exemption documentation must be submitted by September 18th, 2026
  • Cooperative Apartments: Exemption documentation must be submitted by September 18th.

Owners should retain the notice, including the unique response security code/PIN found within the notice, as it will be needed to access the Department’s online response portal.

In light of the August 10, 2026 temporary restraining order, the effect of the court’s ruling on the September 18 response deadline remains to be determined.

Available Exemptions

Exemptions may be available where, among other things:

  • the property is the owner’s primary residence;
  • the property is occupied by a qualifying family member;
  • the property is leased to a qualifying tenant;
  • Any exemption recognized by the Department applies;
  • An immediate family member of the owner or majority interest holder, or
  • The sole beneficiary or beneficiaries of a

Documentation Requirements

The documentation required to support an exemption application depends on the identity of the person who is using the property as a primary residence.

Primary Residence: Owners claiming that the property is their primary residence generally must provide:

  • the occupant’s most recently filed federal or state income tax return; or
  • if a tax return is unavailable, two alternative forms of documentation, such as:
    • a driver’s license or other DMV-issued identification;
    • a voter identification card; or
    • other documentation establishing that the property is the occupant’s primary

Tenant or Subtenant: If the property is the primary residence of a tenant or subtenant, applicants generally must provide the primary residence documentation described above, together with:

  • a copy of the current lease and an additional rental document (such as a utility bill, proof of rent payment, or renter’s insurance policy); or
  • a Tenant or Subtenant Affidavit together with two additional specified rental

Immediate Family Member: If the property is the primary residence of an immediate family member of the owner or majority interest holder, applicants generally must provide the primary residence documentation described above, together with documentation establishing the family relationship, such as:

Business Entity: If the property is owned by a business entity (including an LLC, corporation, trust, or partnership) and is used as the primary residence of a majority member, shareholder, or partner, applicants generally must provide the primary residence documentation described above, together with:

  • the applicable organizational documents (such as a partnership agreement, trust agreement or affidavit, LLC operating agreement, or articles of incorporation); and
  • a Majority Interest Affidavit.

If No Notice is Received

Property owners who believe their property may be subject to the surcharge should not assume that the absence of a notice means that the surcharge does not apply. Even without a notice, a property owner may be subject to the surcharge if a timely exemption application is not filed. As a practical matter, owners should consider:

  • checking their physical mailboxes, as notices were mailed by ordinary mail;
  • reviewing the Department of Finance’s published supplemental market value roll (or other publicly available property list) to determine whether the property has been identified as potentially subject to the surcharge;
  • calling 311 for assistance from the Department of Finance;
  • specifically for cooperative apartments, contacting the managing agent to determine whether the cooperative board received a notice and whether any action is required. Anecdotally, in at least some instances, the Department of Finance has sent surcharge notices to managing agents or cooperative boards rather than directly to some unit

Recommended Client Action and Client Considerations

Clients who receive a notice should:

  • review the notice immediately;
  • preserve the notice and response PIN;
  • gather any supporting documentation establishing eligibility for an exemption;
  • submit all required information before the applicable deadline and
  • consult counsel promptly if there are questions regarding eligibility, valuation, or the documentation required by the Department.
  • If a property owners believe the DOF has incorrectly valued the property, can be filed a challenge, with the New York City Tax Commission.

Property owners who receive a notice should not assume that they are necessarily subject to the surcharge. Rather, the notification begins the administrative review process and provides an opportunity to establish that a property qualifies for an exemption. Because the applicable deadlines are relatively short, clients should promptly review any notice received, gather supporting documentation, and consult counsel as appropriate before the applicable submission deadline.

Special Considerations for Cooperative Apartments

The surcharge for cooperative apartments is imposed upon the cooperative corporation. Because cooperative apartments are owned through a cooperative corporation rather than as separate tax lots, the cooperative corporation remains responsible for payment of any surcharge assessed against the building. As a result, a shareholder’s failure to satisfy a surcharge obligation may expose the cooperative corporation (and, indirectly, other shareholders) to additional interest, liens, or other financial consequences.

Considering these issues, some commentators have suggested that cooperative boards consider whether amendments to proprietary leases are appropriate to address surcharge-related obligations, payment procedures, shareholder indemnification, and enforcement mechanisms. According to Suggested amendments may include the following:

  • require shareholders to pay any Pied-à-Terre surcharge attributable to their unit;
  • establish procedures governing the timing and method of surcharge payments, including installment or escrow arrangements where appropriate;
  • establish procedures for shareholders to contest or challenge surcharge determinations;
  • require shareholders to indemnify the cooperative corporation for surcharge-related liabilities, including applicable interest, penalties, and other costs arising from nonpayment;
  • condition the transfer or assignment of shares on satisfaction of any outstanding surcharge obligations;
  • address trust-related ownership changes undertaken to comply with the surcharge; and
  • establish remedies in the event a shareholder fails to satisfy surcharge-related

Tax Planning Considerations

As discussed in our prior memorandum, the implementation of the pied-à-terre surcharge may result in significant annual carrying costs for owners of high-value secondary residences. Accordingly, affected property owners may wish to evaluate whether it is appropriate to:

  • establish the property as their primary residence, where feasible;
  • convert the property to a qualifying rental use;
  • reevaluate the long-term ownership or use of underutilized residential property;
  • consider other tax planning strategies based on their individual

As the availability of exemptions and the tax consequences of the surcharge are highly fact-specific, clients should consult with their personal advisor regarding the surcharge’s potential impact and available planning opportunities. McLaughlin & Stern is available to assist clients in evaluating the applicability of the surcharge, pursuing available exemptions, and developing appropriate planning strategies.
