New York lawmakers approved a new pied-à-terre tax on luxury second homes in New York City as part of the state’s finalized 2026 budget agreement, passing one of the nation’s most closely watched and controversial housing tax measures.

The legislation, sponsored by Gov. Kathy Hochul and strongly backed by New York City Mayor Zohran Mamdani, targets high-value apartments, condos, and co-ops that are not used as primary residences. State officials say the measure, which is designed to generate up to $500 million a year, is also intended to help address the growing fiscal pressure facing New York City.

The tax officially takes effect July 1, 2026, and is expected to affect about 10,000 luxury properties across the city.

The proposal has been the subject of conversation for months in New York’s luxury real estate market, in the political world, and in the investment community. The bill’s passage is now a big turning point in how state leaders view wealth, housing affordability, and luxury property ownership in New York City.

While the law targets second homes worth $5 million or more, tax calculations are expected to be more complicated than a simple sticker-price threshold.

Under the approved system, the New York City Department of Finance will decide whether a property is a non-primary residence and will determine the taxable market value according to city assessment formulas. Those formulas often are wildly off from actual sale prices, especially. The move came after months of talks between Governor Hochul and Mayor Mamdani, who had originally wanted to raise property taxes much more on wealthy New Yorkers, but opposition from the business world and elements of the real-estate industry led city leaders to adopt the more limited pied-à-terre approach.

The measure emerged after months of negotiations between Governor Hochul and Mayor Mamdani, whose administration has aggressively pushed for higher taxes on wealthy property owners as part of a broader affordability-focused political agenda.

Mamdani had originally pursued far broader property tax increases targeting wealthy New Yorkers, but resistance from the business community and parts of the real estate industry forced city leaders to pivot toward the narrower pied-à-terre framework instead.

Supporters of the tax say the policy reflects growing frustration over the role luxury second homes play in New York’s affordability crisis.

Housing advocates and liberal lawmakers long have lamented the rising number of multimillion-dollar apartments that sit empty much of the year, even as housing costs keep climbing for full-time residents. The problem became especially evident with the emergence of Billionaire’s Row in Midtown Manhattan, where ultra-luxury towers attracted international investors who bought apartments as part-time homes or wealth preservation assets.

“This proposal is a way to raise more revenue from wealthy nonresident owners to help pay for city services and infrastructure without raising taxes on middle-income New Yorkers,” said Governor Hochul.

But supporters view the tax as a fairness measure while opponents say it risks damaging one of New York’s most important economic sectors at a delicate moment for the market.

Luxury brokers, developers, investors, and business leaders have spent weeks warning that the policy could slow demand for high-end New York real estate, discourage foreign investment, and drive wealthy buyers to lower-tax states like Florida and Texas.

Some industry leaders are worried the measure could have ripple effects far beyond ultrawealthy second-home owners.

Managers at Manhattan House Condominium on the Upper East Side recently warned lawmakers that the tax could lower property values throughout entire residential buildings by making luxury co-ops and condominiums less attractive to future buyers. In a letter to state officials, the building’s management said the proposal could hurt retirees, families, and long-term residents who depend on stable property values and market liquidity.

Critics also point to higher carrying costs faced by New York property owners, such as higher insurance premiums, labor costs, maintenance costs, compliance costs, and financing pressure. The added tax burden could further erode confidence in the city’s long-term investment climate, they say.

The debate grew even more heated when billionaire Citadel founder Ken Griffin publicly blasted the proposal and accused city leaders of political targeting of the wealthy. Griffin, who bought a Manhattan penthouse for about $238 million in 2019, said policies like the pied-à-terre tax reinforce the idea that New York is becoming more and more hostile to success and to investment in business.

Griffin has been steadily expanding Citadel’s operations in Miami, which many in the real estate industry see as a symbol of wider migration trends among wealthy individuals and financial firms leaving high-tax states.

Meanwhile, supporters argue that New York's budget realities offer lawmakers few options.

Mayor Mamdani is facing an estimated multibillion-dollar fiscal deficit and is pushing ambitious affordability proposals that include increased transit access, city-supported grocery initiatives, and wider housing programs.

The pied-à-terre tax gained political appeal because it targets a relatively narrow group of ultrawealthy nonresident owners, rather than imposing broad tax increases on the general public.

However, it remains doubtful whether the tax will generate the revenue projected.

State officials estimate annual collections at nearly $500 million, but some analysts say the actual take could be closer to $350 million because of ownership restructuring, valuation appeals, legal battles, and changes in buyer behavior.

Some economists also warn that a slowdown in luxury-transaction activity could cut transfer-tax revenue and partially offset gains from the new policy.

There is also a national trend of more and more Democratic-led states targeting assets related to wealth and individuals with high incomes to help deal with fiscal pressures. Similar measures have been proposed recently in states such as Washington, Maine, Rhode Island, and Massachusetts.

But for the real estate industry in New York, the stakes are especially high.

Luxury real estate has long been one of the city’s most important economic engines, supporting property taxes, jobs in construction, development activity, brokerage revenue, and international investment. But industry leaders now worry the pied-à-terre tax could be a harbinger of a broader movement toward more aggressive housing-related taxation in the years to come.

Meanwhile, affordability pressures continue to mount citywide, with Manhattan rents recently breaking $5,000 for the first time ever and housing shortages remaining severe across much of the metro area.

The battle between affordability politics and investment concerns is now at the core of New York’s housing future.

The tax is on the books, and attention is quickly turning to implementation, enforcement, and the ultimate reaction of buyers, investors, and developers once the policy goes into effect this summer.
