New York City is moving to collect hundreds of millions from owners of luxury second homes, while thousands face losing existing tax breaks. Court challenges and successful homeowner appeals are raising questions about the program’s financial impact.

NEW YORK — New York City Mayor Zohran Mamdani’s new tax on expensive second homes is delivering a costly surprise to wealthy property owners, including Trump administration special envoy Steve Witkoff, whose Manhattan property faces a reported $101,000 surcharge on top of the loss of an approximately $24,000 annual tax break.

The new levy, known as the pied-à-terre tax, targets qualifying properties that are not used as primary residences. But some owners face a double financial blow as city officials also examine whether they improperly received tax reductions reserved for residents who live primarily in New York City.

The Wall Street Journal reported Wednesday that several prominent property owners who primarily reside outside New York have faced increased scrutiny of tax abatements previously applied to their Manhattan apartments.

The policy is part of Mamdani’s effort to generate approximately $500 million annually to address the city’s budget pressures. Its implementation has already prompted lawsuits, thousands of exemption applications and concerns within New York’s luxury real estate market.

What Is the Pied-à-Terre Tax?

The tax applies to qualifying expensive New York City homes that are not anyone’s primary residence.

Under legislation approved as part of New York State’s 2026 budget, the surcharge covers certain one- to three-family houses, condominiums and cooperative apartments.

The threshold and tax rate depend on the property’s classification and valuation method.

For the first two fiscal years, qualifying condominiums and cooperatives generally face the following surcharge rates:

City-assessed property value

Surcharge rate

$1 million–$3 million

4%

Above $3 million–$5 million

5.25%

Above $5 million

6.5%

Different thresholds and rates apply to one- to three-family houses. Beginning in fiscal year 2028–29, the statutory thresholds and rates for condominium and cooperative units are scheduled to change substantially.

The percentages do not mean the city will necessarily charge that percentage of a property’s full market sale price. The law uses prescribed valuation methods and calculations, making a property’s actual assessment critical.

The city says the tax is intended to generate revenue from owners who maintain valuable New York residences without living in them as their primary homes.

Steve Witkoff Faces a Six-Figure Tax Increase

Among those affected is Steve Witkoff, the real estate developer and Trump administration special envoy.

According to The Wall Street Journal, Witkoff’s Manhattan property faces a $101,000 surcharge under the new system.

He also stands to lose an approximately $24,000 annual property tax abatement previously associated with the residence.

Together, those changes represent approximately $125,000 in additional annual tax costs compared with the property’s earlier treatment, assuming both adjustments remain in place.

The abatement issue is separate from the new surcharge.

Certain property tax reductions are reserved for owners who use eligible apartments as their primary residences. The city is examining properties where owners may have received those benefits despite primarily living elsewhere.

That scrutiny has affected other prominent property owners, including executives with principal residences in Florida.

The financial consequences could be substantial for owners of expensive Manhattan apartments who maintain their permanent residences outside New York.

Thousands Challenge the New Tax

The rollout has encountered significant resistance.

According to an October 11 New York Post report, approximately 10,000 exemption applications had been submitted, with about 5,700 already approved.

That means a substantial number of properties initially identified as potentially taxable may not ultimately qualify for the surcharge.

The city has also faced litigation over how it notified property owners and established the list of affected residences.

A Staten Island judge ruled against aspects of the rollout in September, but the city’s appeal produced a stay, allowing implementation to proceed while the legal dispute continues.

Separate lawsuits challenge the tax itself.

These developments create uncertainty about how much revenue the city will ultimately collect and how many owners will be required to pay.

Could the Tax Affect New York’s Luxury Housing Market?

For the real estate industry, the concern extends beyond wealthy homeowners receiving higher tax bills.

New York’s luxury residential market supports brokers, construction and renovation firms, architects, property managers, attorneys, financial institutions and numerous service businesses.

Higher annual ownership costs could influence decisions by buyers considering a Manhattan apartment as a secondary residence.

Some prospective buyers may reassess the economics of purchasing, while existing owners could consider selling, renting or changing how they use their properties.

The extent of that response remains uncertain.

Supporters argue that the tax can generate additional revenue from high-value properties without increasing taxes on ordinary homeowners. They also contend that stricter enforcement of primary-residence tax benefits helps ensure that public subsidies reach eligible residents.

Critics question whether the surcharge will discourage investment in the city and reduce demand in the high-end property market.

Both concerns matter for New York’s broader economy, particularly given the city’s dependence on property taxes and real estate transactions.

Will Mamdani Collect the Projected $500 Million?

The city initially anticipated approximately $500 million in annual revenue from the surcharge.

But the large number of approved exemptions and pending lawsuits could complicate that projection.

The final revenue will depend on how many properties remain taxable, how valuations are determined, how court challenges are resolved and whether owners change their behavior.

New York City must also distinguish between collecting the new surcharge and recovering property tax benefits granted to owners who did not qualify.

The latter is an enforcement question involving existing rules, while the former represents an additional tax burden authorized by new legislation.

For homeowners receiving notices, the practical issue is immediate: determining whether they qualify for an exemption, reviewing the property’s valuation and understanding the applicable appeal procedures.

A Broader Test of New York’s Tax Strategy

Mamdani has made taxing wealthy property owners a central part of his strategy to fund city services and address budget pressures.

The pied-à-terre tax offers an early test of that approach.

The administration must demonstrate that the levy can be administered accurately, withstand legal challenges and generate meaningful revenue.

Property owners, meanwhile, are assessing how the added cost affects their investment decisions and whether they can establish eligibility for exemptions.

For New York’s real estate industry, the question is not simply whether wealthy homeowners can afford higher taxes.

It is whether the city’s effort to raise revenue from luxury properties will produce the anticipated financial benefits without significantly weakening the market activity on which other tax collections and local businesses depend.
