It Begins: Mamdani Plans First NYC Property Tax Hike In Decades To Plug $5 Billion Hole

New York City property owners are set to ‘enjoy’ the first property tax hike in more than two decades as part of a proposed solution by Mayor Zohran Mamdani to fill a roughly $5 billion budget gap, Bloomberg reports.

“He’s put a pretty extreme option on the table, which is a combination of raising property taxes and taking money from reserves and relying on some pretty aggressive revenue projections to boot,” said NYC Comptroller Mark Levine. 

The pitch, set to be unveiled Tuesday afternoon during Mamdani’s preliminary budget proposal, comes one day after Governor Kathy Hochul vowed to kick in another $1.5 billion in additional aid to the city for the current fiscal year and next. Hochul has also committed $510 million for future years to help plug holes in the budget. 

Update: Mamdani has laid out two paths; raise taxes on the ultra-wealthy and most profitable corporations, or ‘balance the budget on the backs of working people using only the tools at the City’s disposal.’

Today, I’m releasing the City’s preliminary budget. After years of fiscal mismanagement, we’re staring at a $5.4 billion budget gap — and two paths.

One: Albany can raise taxes on the ultra-wealthy and the most profitable corporations and address the fiscal imbalance between…

Mamdani says that the state should step up even more. Last week, he called on state lawmakers Wednesday to approve a 2 percent personal income tax increase on the city’s wealthiest residents as well as a hike in the corporate tax rate in a bid to close a multibillion-dollar budget gap. Of note, Hochul and the legislature must approve any tax changes.

While Mamdani is handcuffed in many ways when it comes to raising revenue, raising property taxes is something he can do as part of the annual budget process. Homeowners, meanwhile, just had their assessed values jump 5.6%, which will bring the city an additional $325.8 billion – which is separate of Mamdani’s plan. 

Mamdani’s own rhetoric about the size and scope of the city’s budget situation has shifted. Earlier this month, just two weeks after describing the city’s $12.6 billion budget deficit as the city’s largest since the Great Recession, Mamdani revealed the hole had actually shrunk by $5 billion, because of higher tax revenue, propelled by personal income tax growth and Wall Street bonuses.

Even threatening to raise property taxes could prove a political lightning rod for Mamdani, after campaigning to reform that system, which has been criticized for overburdening lower- and middle-income residents.

Meanwhile last month Mamdani said NYC is facing a $12.6 billion deficit over the next two years, which he blamed on his predecessor, Mayor Eric Adams, whose administration he says underbudgeted for various expenses such as cash assistance, rental assistance for homeless residents, special education and overtime costs. In FY 2025, NYC took in over $33 billion in property tax revenue. 

Mamdani during his campaign promoted progressive reforms to fund proposals such as free public transit, rent stabilization and housing programs, universal child care, and a $30 minimum wage, leading to his upset win over more moderate Democrats.

He called for a 2 percent surcharge on high earners on the campaign trail.

Estimates suggested it could create approximately $4 billion annually to support increased public services and affordability programs, as well as offset costs for broad social investments while not saddling middle- and low-income residents.
