New NYC Pied-À-Terre Tax Faces Its First Big Test
There's some confusion swirling over Mayor Mamdani's "second-home tax" on some high-value homes in New York City.
New York City’s new tax on high-value second homes is moving from the policy stage to enforcement. But the first challenge involves determining which property owners actually owe it.
The pied-à-terre tax was approved as part of the state budget signed into law in May 2026 and applies to certain non-primary residences in NYC beginning the 2026-2027 property tax year.
But as the city begins implementing the new levy, some homeowners are questioning why they received notices indicating their properties might be subject to the tax.

In response to the confusion, the Department of Finance extended the deadline to apply for a pied-a-terre tax exemption until Sept. 18, 2026. The move is designed to give property owners more time to review their notices and provide documentation showing why the tax shouldn't apply.
"We are announcing the extension of the exemption application deadline to ensure that New Yorkers who received the ‘You may be subject to...’ letters have the time and information they need," New York City Mayor Zohran Mamdani said in a statement.
The administration has said the goal is to ensure that residents who shouldn't owe the tax have an opportunity to establish their exemption eligibility.
So, how does New York City’s pied-à-terre tax work and who's actually affected?
NYC Pied-à-Terre Tax exemption deadline extended
NYC’s pied-à-terre tax is a surcharge on certain residential properties that are not used as an owner’s primary residence.
The measure is designed to raise revenue from high-value homes and apartments maintained as second residences, particularly those owned by people who live elsewhere.
Mamdani has described the tax, which is expected to generate about $500 million annually, as "an important new tool to help our city collect the revenue we need for safer streets, cleaner parks, and other critical investments across the five boroughs."
Some key points:
- The new law, which took effect July 1, 2026, applies during the 2026–27 (phase-one) and 2027–28 property tax years.
- The levy applies to certain non-primary residences. That includes one-, two- and three-family homes, condominiums and cooperative units, based on property type and market value.
- One-, two- and three-family homes are subject to the surcharge if the property has a market value of $5 million or more. Condominium and cooperative units are subject to the surcharge if the unit has a market value of $1 million or more.
- Properties used as a primary residence by the owner or an immediate family member are exempt. Properties leased for at least one year as a primary residence may also qualify for an exemption.
It's important to note that the surcharge is not part of a homeowner’s regular property tax bill. Instead, it creates an additional tax obligation for qualifying non-primary residences that meet the applicable value threshold and don't qualify for an exemption.
How much is the tax? The amount a homeowner could owe will depend on the property’s standardized fair market or assessed value and the applicable surcharge rules.
Class 1 (one-, two-, and three-family homes)
- $5 million to $15 million: 0.8%
- More than $15 million to $25 million: 1.05%
- More than $25 million: 1.3%
Condominiums and co-ops (FY 2026-27 and FY 2027-28)
- $1 million to $3 million (Phase One Market Value): 4.0%
- More than $3 million to $5 million (Phase One Market Value): 5.25%
- More than $5 million (Phase One Market Value): 6.5%
Which homeowners actually owe the tax
As the city began implementing the new levy, confusion has emerged over which properties might be subject to it.
- On July 24, the Department of Finance published a list of more than 900,000 properties, prompting some homeowners to question why their homes appeared on the list.
- The city later added a disclaimer clarifying that inclusion on that larger list didn't necessarily mean a property was subject to the pied-à-terre tax.
The city's Department of Finance has since reportedly sent notices to about 17,000 property owners who may be affected by the new surcharge. (That number was larger than the state’s earlier estimate of roughly 10,000 to 13,000 affected non-primary residences, which has raised questions about how many properties will ultimately qualify once exemptions are reviewed.)
Some homeowners are reportedly concerned about the notices they received.
For example, a Brooklyn homeowner told The Wall Street Journal that he received a notice indicating a potential $44,048 surcharge, despite stating that the property was his primary residence. The Gothamist reported on another New York resident who said she would owe close to $43,000 in tax without an exemption for a property she says has always been her primary address.
Those types of disputes highlight why implementation could prove difficult. The city is not only identifying valuable properties — it's trying to determine how those properties are actually used.
Under NYC law, the surcharge generally applies to qualifying properties that are not used as a primary residence. The Department of Finance determines primary residency based on legal factors, including whether the property is occupied for a majority of days during the calendar year by a covered owner.
But…in some cases, that determination may require more than a review of ownership records.
- A property deed may show who owns a home, but it doesn't necessarily establish how the property is used
- Properties held through trusts, limited liability companies, or other ownership structures may require additional review
- The city may request documentation related to residency, occupancy, ownership details, or other information relevant to an exemption
For homeowners who received notices, a key challenge could be showing their property doesn't meet the criteria for the surcharge.
What NYC homeowners need to know
Keep in mind: Receiving a notice does not automatically mean a homeowner owes NYC’s second-home tax. Instead, it means the property has been identified as potentially subject to the new rules and the owner may need to submit information showing why an exemption applies.
City officials have said that homeowners who believe their properties shouldn't be taxed under the measure should complete the exemption application by Sept. 18, 2026.
The documentation required will depend on each homeowner’s circumstances. The Department of Finance has a webpage that includes frequently asked questions, an eligibility tool, and instructions for submitting documentation.
And since every homeowner's situation is different, you may want to consult a trusted tax professional who can help you determine whether your property qualifies for an exemption.
