When Zohran Mamdani won the New York City mayoral race in November 2025, he ran on a mandate to tax the rich and protect working New Yorkers. Five months into the job, he's getting his first real test of whether he can keep up with that promise.
Facing a $12 billion (1) budget gap (2), his opening move was proposing a 9.5% property tax hike on homeowners, which would raise $3.7 billion toward the shortfall. He called it a "last resort" if New York State wouldn't come to the table to provide financial help.

In the end, the state offered $4 billion in aid. So on Tuesday, Mamdani was able to drop the property tax hike entirely (3) as he unveiled a $124.7 billion executive budget for fiscal year 2027, noting he "refuses to slash services."
"It has not been easy, but we have balanced the budget, and we have done so without placing the burden on the backs of working New Yorkers," he said at a press conference at city hall (4).
Why a 9.5% hike was always a long shot
New York City's property taxes are the city's largest single revenue source, bringing in $30 billion every year — more than any other levy, including income and sales taxes (5).
The median homeowner pays $6,317 per year in property taxes (6) in the city. A 9.5% hike would add about $600 a year to that. With a cost of living that makes New York one of the world's most expensive cities, that's a hit (7) on pocketbooks.
City Council Speaker Julie Menin slammed the door on the tax hike right away (8). In principle, Mamdani could raise property taxes without the state's sign-off, but he would need council's support without Menin's vote, the motion would fail.
Still, looks like the property tax proposal was Mamdani's leverage to get New York State to negotiate.

How Mamdani closed the gap
Mamdani filled a $5.4 billion budgetary hole in many ways, according to Bloomberg Tax (9). His chief savings officers were able to dig up $1.77 billion in efficiencies (mostly by not filling vacancies), along with tweaks to education mandates and subsidies (10).
The single largest piece is $2.3 billion saved over the course of two years from pension amortization. Since 2013, the city has been trying to play catch-up (11) on the funds it needs to cover city employees' pensions. Mamdani's move would let the city spread out additional pension contributions over more years, easing this year's budget pressure.

The pension amortization requires state approval and sign-off from the city's five pension funds (12). Even if it passes, it's an imperfect solution as the total pension debt just gets deferred, not erased.
Perhaps the most controversial way Mamdani's administration proposes to balance the budget is with the pied-à-terre tax, projected to generate $500 million a year (13), though details are unclear pending state approval.
Governor Kathy Hochul introduced the idea last month as a targeted surcharge on luxury second homes valued over $5 million and owned by non-New York City residents who spend little time in the city.
Mamdani supported the idea on social media, literally calling out billionaire Citadel CEO Ken Griffin as a target in front of his $238-million penthouse. In response, Griffin pushed back hard (14).

"With 1% of New York taxpayers paying 45% of all the taxes, the city is in a precarious position if they make those who create value feel like they're best off moving their businesses and their lives to other jurisdictions," Griffin told CNBC (15).
High earners leaving the city would reduce the tax base Mamdani is counting on (16).
The budget still needs council and state approval, and even if it's approved, Mamdani still has to contend with the structural problems that created the budgetary shortfalls.
What this means for New York City homeowners
For now, the 9.5% property tax hike is off the table.
Long term, it's not so simple. Mamdani stepped into a $12 billion structural deficit and a tax system leaning heavily on the city's wealthiest residents, challenges that won't vanish from a single budget cycle.
If the pied-à-terre tax and pension amortization don't get approved, the property tax hike could be back on the table at some point.
