NEW YORK, NY (TDR) — New York City Mayor Zohran Mamdani unveiled his first preliminary budget Tuesday, laying out a $127 billion spending plan that forces a stark choice onto state lawmakers and city residents alike: either Albany approves new taxes on the wealthiest New Yorkers and most profitable corporations, or the city raises property taxes on millions of residents for the first time since the Great Recession.

The democratic socialist mayor, now 48 days into his term, framed a proposed 9.5 percent property tax increase as a painful last resort to close what his administration says is a $5.4 billion budget gap inherited from former Mayor Eric Adams. The first property tax rate hike since 2003 would impact more than 3 million residential units and over 100,000 commercial buildings, generating approximately $3.7 billion in new revenue.

But the proposal drew immediate fire from every direction — from the governor who refuses to raise taxes in an election year, from fiscal watchdogs who say the city has a spending problem rather than a revenue problem, from the City Council speaker who called it a non-starter, and even from Mamdani's own political allies who warned it would devastate the communities of color the mayor claims to champion.

A $12 Billion Deficit Meets Campaign Promises

When Mamdani took office on Jan. 1, he inherited a fiscal situation that, depending on who is telling the story, was either a crisis of his predecessor's making or a predictable consequence of years of bipartisan overspending.

City Comptroller Mark Levine estimated in January that New York faces a $12.6 billion shortfall over the next two fiscal years — a $2.2 billion projected deficit on the city's $116 billion budget for fiscal 2026 and a $10.4 billion gap in fiscal 2027. Mamdani's team has since reduced that figure to $5.4 billion through Wall Street bonus revenue, state aid and reserve drawdowns, but the structural imbalance remains enormous.

Mamdani has blamed the crisis squarely on Adams, calling it "the Adams Budget Crisis" and accusing his predecessor of systematically underbudgeting essential services. At a January press conference, he pointed to specific examples: Adams budgeted $860 million for cash assistance in fiscal 2026, even though current projections put the cost at nearly $1.7 billion.

"This crisis has a name and a chief architect. In the words of the Jackson 5, it's as easy as ABC. This is the Adams Budget Crisis."

Adams was not amused. A spokesperson fired back that the former mayor inherited nearly $10 billion in debt compounded by the COVID-19 pandemic. Adams himself posted on X that Mamdani had "promised a laundry list of 'free' giveaways to buy votes, with no plan to pay for them."

"Now that the math doesn't work, instead of owning the fact that he misled New Yorkers, he's blaming me."

Former Gov. Andrew Cuomo, whom Mamdani defeated in the stunning 2025 Democratic primary upset, also punched back through a spokesperson, noting that Mamdani served five years in the state legislature and "couldn't even be bothered to show up for work."

The Tax Debate: Revenue Problem or Spending Problem?

The core tension in Mamdani's budget plan is whether New York City faces a revenue problem — as the mayor argues — or a spending problem that no amount of taxation can resolve.

Mamdani's preferred path requires state approval: a 2 percentage point income tax increase on individuals earning more than $1 million and raising the combined corporate tax rate to just over 22 percent. He says these measures would fund "free" childcare, free bus service and other campaign promises while addressing a structural fiscal imbalance in which New Yorkers contribute 54.5 percent of state revenue but receive only 40.5 percent back.

Gov. Kathy Hochul has flatly rejected this approach, repeatedly stating that raising taxes is a non-starter.

"The news flash, maybe to you if you haven't heard me, we are not raising taxes in the state of New York. I'm not raising taxes for the sake of raising taxes."

On Monday, Hochul offered Mamdani a $1.5 billion state aid package over two years, including $300 million for youth programming, $150 million in restored sales tax revenue and $500 million for "shared priorities." That narrowed the gap but left billions unresolved.

The Citizens Budget Commission, a nonpartisan fiscal watchdog, argues Mamdani is presenting voters with a false choice. Its president, Andrew Rein, said the mayor's plan ignores the most obvious option: reducing spending.

"Mayor Mamdani's preliminary budget proposes a false choice: either the state raises personal income and business taxes, or the city raises property taxes and saps money from reserves. The best choice is to eliminate spending that does not improve New Yorkers' lives and make government more efficient and effective."

The numbers support the watchdog's concern. New York City's budget has ballooned 55 percent in a decade — former Mayor Bill de Blasio proposed an $82.1 billion spending plan in 2017, compared to the $127 billion outline Mamdani put forward Tuesday. The Tax Foundation's 2026 State Tax Competitiveness Index already ranks New York 50th overall, weighed down by a 10.9 percent top individual income tax rate, the city's own progressive income tax, high combined sales taxes and elevated property taxes.

Meanwhile, Mamdani's campaign promises carry enormous price tags. Free bus service is estimated at $700 million per year. Universal childcare could cost as much as $6 billion annually. His housing plan calls for $100 billion in spending, with $70 billion borrowed. Tuesday's preliminary budget notably did not include funding for free buses, city-run grocery stores or a new department to handle mental health calls — items the administration said would appear in an April update.

The Property Tax Paradox

The irony of Mamdani's property tax proposal is that it directly contradicts one of his central campaign promises.

During the mayoral race, Mamdani explicitly campaigned on reforming the city's property tax system to "shift the tax burden from overtaxed homeowners in the outer boroughs to more expensive homes in richer and whiter neighborhoods." His campaign website described a property tax system that penalizes homeowners in predominantly Black and Latino neighborhoods like Jamaica, Brownsville and Tremont while undertaxing luxury properties in Manhattan and Brooklyn brownstone corridors.

On Meet the Press after his primary victory, Mamdani defended the racial framing as merely descriptive of existing inequities rather than a race-based tax policy.

"That is just a description of what we see right now. It's not driven by race. It's more of an assessment of what neighborhoods are being under-taxed versus over-taxed."

But the 9.5 percent blanket property tax increase he proposed Tuesday would do precisely the opposite of what he promised — it would raise rates across the board without reforming the underlying system, hitting homeowners in communities of color hardest.

Comptroller Levine acknowledged this contradiction after being briefed on the plan.

"It's essentially a regressive tax as it's currently structured, hitting homeowners and communities of color much more than it hits homeowners in wealthier areas. So, this should not be anyone's choice of how we solve this."

City Council Speaker Julie Menin and Finance Committee Chair Linda Lee issued a joint statement rejecting the proposal outright.

"At a time when New Yorkers are already grappling with an affordability crisis, dipping into rainy day reserves and proposing significant property tax increases should not be on the table whatsoever."

Queens Borough President Donovan Richards called it "absolutely a non-starter," warning it would "force people out of their homes." Deputy Council Speaker Nantasha Williams, who represents predominantly Black homeowners in Southeast Queens, called the plan inequitable and "deeply tone-deaf to Black, Brown, and working-class homeowners."

Business Community Sounds Alarm

The business community's reaction was equally hostile. Steven Fulop of the Partnership for New York City warned that a 22 percent corporate tax environment would drive businesses to lower-tax states.

"Somebody looking to open a new business, start a new corporation, the next Amazon, is never going to make the choice to open in an environment where their 22% tax rate is. They're going to choose Florida. They're going to choose Texas."

Hedge fund manager Bill Ackman has warned that businesses and wealthy residents "have already started making arrangements for the exits."

Mamdani dismisses capital flight fears, noting that the number of millionaires in New York increased after the state raised taxes on the wealthy in 2021. Academic research from Cornell University supports a more nuanced view — only about 2.4 percent of Americans with million-dollar incomes move across state lines each year, roughly half the rate of low-wage workers.

But the Citizens Budget Commission cautioned that tax increases would raise what are already the highest rates for high-income earners and corporations in the country, risking competitiveness "at a time of domestic outmigration, declining international immigration, and stagnant jobs numbers."

The Options Nobody Is Discussing

Lost in the binary debate between taxing the rich and hiking property taxes are alternative revenue strategies that require neither. The Center for an Urban Future recently identified five revenue-raising options that could generate more than $1.4 billion annually without raising any tax rate.

The most lucrative: expanding metered street parking. Only 80,000 of the city's 3 million parking spaces are currently metered. If one quarter were metered, focusing on commercial corridors, the city could raise more than $1.3 billion per year while reducing congestion. Other proposals include developing housing on CUNY parking lots and establishing fees for autonomous vehicles.

Rein also pointed to Mamdani's own executive order requiring every city agency to appoint a "Chief Savings Officer" as a step in the right direction — but one that has yet to produce specific savings.

"There's plenty of big opportunities, but also that scalpel within each agency, shrinking spending, being more efficient."

A Vital City analysis raised perhaps the most inconvenient point for Mamdani's narrative: the budget crisis was widely known throughout 2025 but was "conveniently ignored by Mamdani and the New York City press corps during the mayoral campaign." The analysis noted that Mamdani's own ally, then-Comptroller Brad Lander, estimated in August 2025 that the city would face an $8.8 billion gap in fiscal 2027 — before Mamdani won the election by promising billions in new spending.

What Comes Next

Mamdani's preliminary budget is the opening salvo in what promises to be months of tense negotiations. The City Council must approve any property tax increase, and Speaker Menin has made clear that won't happen easily. Albany must approve any income or corporate tax changes, and Hochul faces reelection this November — making wealth tax approval politically treacherous for the governor.

The city budget is legally due by July 1. An executive budget update is expected in April, where the administration has said it will include funding details for campaign promises like free buses and city-run grocery stores. Agency-level savings reports are due by March 20.

Treasury Secretary Scott Bessent has previously called Mamdani's economic proposals "old ideas that have never worked," and with federal aid to the city expected to shrink during the Trump administration, the fiscal pressure on New York is unlikely to ease.

Mamdani himself acknowledged the difficulty of his position Tuesday, even as he insisted his preferred approach — taxing the wealthy — remained the right one.

"We remain firmly within a budget crisis. It is a crisis that we can and will overcome — but we cannot do so without either significant structural changes in Albany, or the painful decision of last resort."

When a city's budget has grown 55 percent in a decade to $127 billion and its leader frames the only options as taxing the rich or taxing everyone else, at what point does the conversation shift from who should pay more to whether the government should spend less — and who gets to make that call?
