NYC Pied-à-Terre Tax: Rates, Exemptions, and Legal Challenges

New York City's new pied-a-terre tax has become one of the most transformative, and controversial, changes in the City's tax code. In April, New York Governor Kathy Hochul and New York City Mayor Zohran Mamdani announced the tax, officially naming it the Non-Primary Residence Property Surcharge.

Given its newness and uncertainty, the tax and its assessments are ripe for challenges. In my experience, it often makes sense to challenge any notices or assessments you receive if you are unsure as to whether it applies to you. At a minimum, challenging this new tax can result in significant reductions on the underlying tax, penalty and interest. The tax also presents opportunities to challenge its procedure as we have already seen in the first few months of implementation.

The pied-a-terre tax was part of a series of tax policy changes designed to address the city's long-term budget challenges without compromising essential services. The first tax of its kind in NYC, the surcharge operates as an annual recurring property tax that targets non-primary, luxury properties. Early estimates reveal that the pied-a-terre tax could bring in an additional $500 million in annual tax revenue.

As of July 1, 2026, the tax is in effect, and the city has distributed official notices to homeowners that will be impacted within the 2026-27 tax year. The rollout, however, has been met with legal challenges and pushback from critics of the tax.

New York — Sales Tax

How Does the NYC Pied-a-Terre Tax Work?

What Properties Are Subject to the Surcharge?

NYC's pied-a-terre tax is a surcharge placed on qualifying residential properties that are not used as primary residences. Authorized by New York State under Tax Law Article 30-C, this recurring surcharge will be added to regular property taxes for high-value, non-primary residences.

The tax only applies to homes that are not the primary residence of the owner or are not rented to a primary resident or occupied by the owner's family. This arrangement helps ensure that property owners who do not live or pay income tax in the City are still contributing to the funding of policing, parks, and other services.

What Are the Surcharge Rates?

For 2026-27 and 2027-28 tax years, the rates for one-, two-, and three-family homes are: 0.8% on DOF market values of $5,000,000 or greater but less than $15,000,000; 1.05% on values of $15,000,000 or greater but less than $25,000,000; and 1.3% on values of $25,000,000 or greater. For condominium and cooperative properties: 4.0% on values of $1,000,000 or greater but less than $3,000,000; 5.25% on values of $3,000,000 or greater but less than $5,000,000; and 6.50% on values of $5,000,000 or greater.

For all eligible properties and property owners, the surcharge will appear on upcoming property tax bills that are due January 1, 2027. However, not all luxury properties or second homes qualify for the tax. There are many circumstances that may qualify for an exemption.

Who Is Exempt from the NYC Pied-a-Terre Tax?

Who Qualifies for an Exemption?

The NYC Department of Finance has distributed approximately 17,000 notices to property owners who may need to pay a supplemental tax amount. However, the pied-a-terre tax does not apply to all second homes or non-primary residences. Properties are not subject to the surcharge if they are the primary residence of: the owner of the property; a tenant or subtenant; one or more individuals who collectively hold a majority interest in the LLC, corporation, or partnership that owns the property; an immediate family member of the owner or majority interest holder; or the sole beneficiary or beneficiaries of a trust.

How Do You File for an Exemption?

If you believe you received the notice letter in error, or if you would like to file an exemption, you must do so by September 18, 2026. By submitting residency documents, such as recent federal or state tax returns or driver's licenses, or tenant documents, like an active lease, property owners can request an exemption from the additional fees.

This is a hard deadline. Missing it could mean paying a surcharge you do not actually owe. If you have any doubt about whether the exemption applies to your property, file anyway and let the City sort it out. The cost of doing nothing is far higher than the cost of filing.

Legal Battle: What Is the O'Brien Lawsuit?

What Is Being Challenged?

In response to the Mamdani Administration's rollout of the pied-a-terre tax, a small group of homeowners filed a lawsuit against the City. The lawsuit is not challenging the new policy itself, but rather, how it was implemented.

The Petitioners-Plaintiffs, Rachel O'Brien, Carmine Morano, and Simon Hedley, are challenging two main components of the implementation. First, on July 24, 2026, the Department of Finance published a list containing nearly 900,000 New York City homeowners' names, addresses, and property values described as related to the Surcharge. Second, the City sent a letter to 17,000 homeowners notifying them that they may be subject to the surcharge.

The lawsuit alleges that the implementation approach unfairly shifted the burden to homeowners to prove that they are not subject to the tax, instead of the City taking on all of the due diligence.

Where Does the Case Stand Now?

On Monday, August 10th, Staten Island judge Wayne M. Ozzi issued a temporary restraining order against the Mamdani Administration, essentially pausing the rollout. However, Mamdani's team filed an appeal, triggering an automatic stay until the appeal is heard. This means that the City can continue with the surcharge implementation for now.

The next hearing with Ozzi is scheduled for August 31st, very close to the September 18th exemption filing deadline. Since the timing of the hearing does not leave much buffer room for City officials or property owners to respond, all eyes should be on the hearing outcome at the end of this month.

In the interim, the city successfully appealed the restraining order. The city can proceed with the rollout as of August 13, 2026. The next major hurdle is the August 31 hearing back at the Supreme trial court.

What Happens Next for NYC Property Owners?

What Should You Do Before August 31?

The future of New York City's pied-a-terre surcharge will depend on the outcome of O'Brien v. New York, as well as how the City responds to concerns regarding the implementation. At this time, the surcharge is still in effect, and impacted homeowners should be prepared to respond accordingly.

If you think that your property is exempt from the surcharge, be sure to file for an exemption by September 18, 2026. Property owners should review their notice carefully, gather documentation establishing primary residence status, and monitor the legal proceedings for any changes that could affect the new tax policy. When in doubt, challenge your assessment.

When Should You Get Professional Help?

As the City moves forward with its proposal, questions about eligibility, exemptions, and property valuation methods are becoming increasingly important. New York City residents who are not sure how to respond to a surcharge notice may benefit from a consultation with an experienced New York tax attorney.

When a new tax like this rolls out with contested implementation, the playbook is familiar: respond on time, document everything, and do not assume the government's assessment is correct just because they sent a letter. State and city agencies make mistakes, especially in the early days of a new regime. The burden may be on you to prove you do not owe it, but that does not mean you should pay without scrutinizing the underlying determination first.
