New York City Mayor Proposes $500 Million Annual Tax on Luxury Second Homes

On April 15, 2026, Governor Kathy Hochul stood with New York City Mayor Zohran Mamdani and City Council Speaker Julie Menin to endorse an annual surcharge on luxury second homes in New York City valued at $5 million or more — a tax structure that would apply to roughly 13,000 properties and, in the administration's projection, raise at least $500 million a year in recurring revenue for the city [1][2][3]. The proposal, known as a pied-à-terre tax, has been drafted, introduced, and buried in Albany repeatedly since 2014. This is the first time a sitting governor and a sitting New York City mayor have both publicly pushed it forward in the same budget cycle [4][5].

The politics have shifted. The policy questions have not.

What the proposal actually does

The surcharge would apply to one-to-three-family homes, condominiums, and cooperatives in the five boroughs with a market value at or above $5 million — but only where the owner's primary residence is outside New York City [1][6]. Units occupied full-time by their owners or leased to full-time tenants would be exempt. The $500 million annual revenue figure comes from the Mayor's office and assumes the tax applies to about 13,000 non-primary-residence units [3][7].

Hochul's office has framed the policy as a "targeted surcharge on second homes and investor-owned apartments worth over $5 million, homes that in many cases sit vacant for a large part of the year" [2]. State lawmakers still have to approve the measure, and the proposal is expected to be folded into the state budget, which was already months behind schedule as of mid-April [1][6].

The $500 million projection is the latest in a long series of estimates that have varied by more than three-to-one. In 2019, the last time a comprehensive pied-à-terre bill moved in Albany, sponsors projected $650 million to $665 million in annual revenue, while the Real Estate Board of New York (REBNY) countered with an industry analysis estimating $372 million [4][5]. In January 2021, the City's Independent Budget Office (IBO) estimated that a pied-à-terre tax could generate roughly $232 million, assuming rates between 0.5% and 4% of market value and different structures for co-ops and condos [8]. The spread between these figures reflects genuine disagreement about how much behavior — sales, reclassification to primary residence, restructuring through LLCs and trusts — the tax would induce.

A 12-year legislative graveyard

The pied-à-terre concept dates to 2014, when then-state-Senator Brad Hoylman-Sigal drafted legislation in response to concerns about non-resident ownership in Manhattan's ultra-luxury market [5]. The bill stalled. It was revived in 2019 after hedge-fund billionaire Ken Griffin bought a penthouse at 220 Central Park South for $238 million and described the purchase as a "place to stay when he's in town" [4][5].

That 2019 push appeared to have momentum — until it didn't. The bill was blocked after what contemporaneous reporting described as intense lobbying pressure from real estate developers, who "hired well-connected lobbyists and presented legislators with printouts of economic analyses" and warned that the high-end market would collapse [4]. Instead of a recurring pied-à-terre levy, Albany that year enacted a one-time progressive mansion tax and an increase in the transfer tax on luxury sales [4][5].

What has materially changed in 2026 is the composition of the coalition. Mamdani, a democratic socialist who campaigned on freezing rent-stabilized rents, making city buses fare-free, and raising taxes on "millionaires and the most profitable corporations," took office in January and has pushed for higher taxes on wealthy New Yorkers as a condition of closing a fiscal gap he has publicly blamed on the Adams administration [9][10][11]. Hochul — who in a prior cycle expressed skepticism about a new luxury tax — reversed position and is now the proposal's top-billed sponsor [12]. Menin, the Council Speaker, called the plan "a smart, sensible proposal" [13].

Who actually pays

The narrative of the tax, particularly as Mamdani frames it, centers on hedge-fund managers and foreign oligarchs using New York condos as storage vehicles for offshore wealth. The canonical example cited across coverage is 220 Central Park South, whose buyers have included Griffin, hedge-fund manager Daniel Och, Alibaba co-founder Joe Tsai (who paid $157.5 million for two units), pharmaceutical billionaire Ge Li, Paramount Group CEO Albert Behler, and a long roster of buyers who purchased through LLCs that obscure the ultimate owner [14].

Foreign buyers are a meaningful share of the relevant market but not the dominant one. Industry data indicates foreign nationals account for roughly 15–18% of high-end Manhattan condo transactions, with international buyers purchasing an estimated $4.5 billion of NYC condos annually [15]. In the first half of 2025, foreign buying activity roughly doubled from the prior year [15]. The remaining majority — domestic hedge-fund principals, private-equity partners, corporate executives, and high-net-worth heirs — are the larger share of who would sit for the surcharge.

The $5 million threshold is high enough that few middle-class "inherited beach house" scenarios are implicated in the five boroughs, where the median NYC home is orders of magnitude below that mark. For national context, the most expensive state average in 2023 was Hawaii at $846,400, roughly one-sixth of the proposal's threshold [CHART-1]. Still, the policy does reach owners below the billionaire tier: a brownstone owner whose property has appreciated past $5 million but who lives primarily in Westchester or Connecticut would be in scope, as would a co-op shareholder whose unit crossed the threshold through decades of market appreciation.

Legal authority and the Albany question

The mayor cannot levy this tax by executive action. New York City's authority to impose new taxes is constrained by the state constitution and the Municipal Home Rule Law; most significant local tax changes require state legislative authorization and often a city "home rule message" requesting that authorization [16]. The proposal as announced is being advanced through the state budget process, which means the State Senate and Assembly must pass it for it to take effect [1][6].

A separate question is whether the tax, once enacted, would survive constitutional challenge. Legal commentary on prior versions has focused on the dormant Commerce Clause of the U.S. Constitution, which bars states from enacting tax regimes that discriminate against interstate commerce [17]. Because the proposed surcharge triggers based on whether an owner's primary residence is outside New York City — a proxy that correlates with out-of-state residency — litigants could argue the statute facially discriminates against non-residents [17]. Drafters of earlier versions attempted to mitigate this risk by defining the tax around "non-primary-residence" rather than "non-resident ownership" status, and a 2018 legal analysis concluded the tax was likely constitutional if drafted carefully [17]. Enforcement also raises practical questions: REBNY Vice President Zachary Steinberg has questioned how the city will determine ownership when homes are "typically owned by individual limited liability corporations or trusts" [4].

Evidence from elsewhere

The strongest evidence cited by supporters comes from Vancouver, which implemented an Empty Homes Tax (EHT) in 2017 at a rate of 1% on vacant properties, later raised to 3% [18]. The number of declared vacant homes fell 67% between 2017 and 2024, from 2,538 to 979, and the program has generated over $194 million, with roughly $170 million directed to affordable-housing initiatives [18][19].

Academic analysis suggests the tax brought several thousand units into long-term use: one study estimated 5,355 fewer vacant units in Vancouver between 2016 and 2021 than would have existed absent the tax, and the city-wide rental vacancy rate widened by roughly 1.5 percentage points [20]. But the same body of research also found that the EHT "had no impact whatsoever on the average rent" — that is, the tax improved availability without measurably improving affordability for middle-income renters [20][21].

London took a different approach: the UK imposes a 3% stamp duty surcharge on second homes and an additional 2% on non-resident buyers, producing a combined surcharge of up to 5 percentage points on top of standard rates for foreign buyers acquiring additional property [22]. Because the surcharge is a one-time transaction tax rather than a recurring levy, its effect on ongoing housing use is indirect — it slows acquisition but does not reach existing holdings. Paris has applied both: a surcharge on the recurring taxe d'habitation of up to 60% in so-called "zones tendues" (tight zones), with 40% of designated communes adopting the maximum rate, on top of doubling the tax on vacant homes [23].

Comparing policy structures across cities is informative, but the most honest summary of the international evidence is this: taxes of this type reliably generate revenue and reliably shrink the vacant-unit population, but there is limited evidence they lower rents for non-luxury housing [20][21].

The steelman against

The arithmetic of housing supply is the central challenge to supporters' housing-affordability claims. NYC's rental vacancy rate in the most recent Housing and Vacancy Survey sits at roughly 1.4%, the lowest reading since 1968, against a housing stock of roughly 3.6 million units [24]. From 2010 to 2023, jobs in the city grew 22% while housing stock grew only 4% [24]. Independent estimates put the structural supply shortfall in the hundreds of thousands of units.

Against that shortfall, the proposal targets 13,000 properties — and not all of those would plausibly enter the rental market if the tax took effect. Some owners would reclassify their NYC apartments as primary residences to escape the surcharge (and absorb the state tax implications of doing so); others would sell to owner-occupants at the top of the market, which does add owner-occupied supply but not rental supply; and a share would simply pay. Even if the tax produced a few thousand newly available rental units, housing economists note that those units would price in the luxury tier and would not materially move the median rent line that confronts middle-income households [24].

Supporters generally concede this point and reframe the proposal as primarily a revenue measure rather than a supply measure — money that can fund affordable-housing construction, rental assistance, or broader city services [1][9]. That framing, however, creates a different risk: a revenue stream whose base is inherently elastic. If property reclassification, sales, or a successful legal challenge reduces the pool of taxable units, the $500 million projection could look more like the IBO's $232 million estimate than the governor's top-line number [8].

The opposition's dollar signs and arguments

REBNY, which represents the city's largest real estate interests, has come out firmly against the proposal. REBNY President James Whelan called it "an annual tax [that] will weaken the city's broader economy — all without addressing its fiscal problems in the first place," predicting the measure will "eliminate thousands of construction jobs, lower property values, and raise costs for New Yorkers" [4][25]. Brokers and developers have echoed the same message: Compass agent Jason Haber characterized it as "death by a thousand cuts," warning of "a breaking point… where even the wealthiest people say I want nothing to do with this" [25]. Serhant's Ravi Kantha predicted wealthy owners would sell at reduced prices rather than accept the carrying cost [25].

Public filings of lobbying-dollar amounts specific to this 2026 cycle are not yet disclosed in the reporting reviewed for this article, and REBNY has not to date published an alternative revenue or housing proposal tied to this specific fight [4][25]. The industry's historical playbook, however, is well-documented: in 2019, developers commissioned economic analyses, enlisted contract lobbyists, and placed opinion pieces arguing the luxury market would collapse under the tax [4]. Some real estate voices have also floated that the surcharge could, paradoxically, encourage some buyers to register NYC homes as primary residences — a behavioral response that, if widespread, would reduce the tax base without necessarily changing how units are used [25].

What the money is supposed to fund

Mamdani has presented the tax as part of a broader rebalancing of who pays for city services. His preliminary $127 billion budget, introduced in January, proposes a 2 percent surtax on millionaires and an increase in the combined corporate tax rate to just over 22%, alongside spending on rental assistance, shelter operations, and special education that the administration argues were chronically underfunded in Adams-era budgets [10][26]. The administration has also pointed to Mamdani's signature campaign promises — fare-free city buses (estimated at roughly $800 million per year) and a freeze on rent-stabilized rents — as initiatives that require durable new revenue [27][28].

The City Council has pushed back. In its April 1, 2026 preliminary budget response, the Council identified $6 billion in alternative resources and rejected property tax increases and drawdowns of reserves [29]. That internal Democratic disagreement — over whether to close the gap primarily with new taxes, savings, or reserve drawdowns — is the backdrop against which the pied-à-terre proposal is being negotiated.

If the revenue projection proves optimistic, the administration has not publicly specified which programs would absorb the shortfall. That contingency planning is likely to be worked out inside budget negotiations rather than announced separately.

What to watch

Three questions will determine whether the proposal survives the spring:

First, the rate schedule. The prior IBO-analyzed structure used marginal rates from 0.5% to 4% of assessed market value above $5 million for houses, and 10% to 13.5% of assessed value above $300,000 for co-ops and condos [8]. Hochul's announcement did not lock in a final rate schedule, and the effective rate will shape both the revenue estimate and legal exposure [6].

Second, the legislative calculus in Albany. With the budget already delayed and the state Senate and Assembly not uniformly aligned with the governor on every tax question, the path to passage runs through members whose districts include luxury-property interests or who are responsive to REBNY lobbying pressure [1].

Third, the treatment of LLC and trust ownership. If the final statute cannot pierce corporate opacity, the 13,000-property estimate may shrink materially, because much of the ultra-high-end condo market is held through entities rather than natural persons [4]. Drafting that addresses beneficial-ownership disclosure, perhaps in tandem with the federal Corporate Transparency Act framework, would meaningfully determine whether the revenue target is achievable.

The pied-à-terre tax arrives in 2026 with a stronger political tailwind than at any point in the past decade — a governor willing to sign it, a mayor who campaigned on it, and a council speaker backing it. Whether that coalition is sufficient to overcome a legislative record of repeated defeats, an organized industry opposition, and a base of owners with the legal resources to contest enforcement is the question that will be answered in Albany in the coming weeks.
