New York City is facing a projected $5.4 billion budget deficit, and the question on many residents’ minds is simple: how does Mayor Mamdani intend to close that gap?
The short answer is that he has signaled a willingness to raise taxes, particularly on high earners, to preserve city services and avoid deep cuts. The details, and the political realities behind them, are far more complex—and they matter a great deal for anyone who lives, owns, or rents in the city.
The Original Idea: Raise Income Taxes on High Earners
Mamdani’s first, headline‑grabbing proposal focused on the city’s highest earners.
The plan:
- Raise the New York City income tax rate on those earning over $1 million per year from 3.88% to 5.88%.
- That is a 2% rate increase, which equates to roughly a 51% increase in NYC income taxes for that group.
- Importantly, he has indicated that the higher rate should apply to the entire income, not just the portion above $1 million (roughly $20,000 per million).
This approach is being framed as “fair” and “targeted”—impacting only the top of the income spectrum, while protecting services that benefit the broader population. On paper, it is an elegant solution: tap the wealthiest residents to close the gap and preserve programs such as universal childcare and free buses.
There is one major problem: the city cannot do this on its own.
The Albany Reality: Who Actually Controls Income Tax Rates
New York City does not have unilateral authority to rewrite its income tax structure. Any significant adjustment to personal income tax brackets or surcharges must go through Albany, meaning:
- The State Legislature would need to pass enabling legislation.
- Governor Hochul would then need to sign it into law.
Governor Hochul has been publicly resistant to raising income taxes on high earners, especially heading into an election cycle. Even if the mayor were able to persuade a critical mass of state legislators to support the increase, the governor’s veto power remains a meaningful barrier.
In practical terms, this means the millionaire tax proposal is as much a political signal as it is a concrete policy path. It reflects priorities and values, but it is unlikely to become law in its current form.
The Pivot: A 9.5% Citywide Property Tax Increase
Because the city’s ability to raise income taxes is constrained by state control, Mamdani has turned to one of the few levers City Hall can pull more independently: property taxes.
His latest proposal:
- A 9.5% increase in citywide property taxes, described as a “last resort.”
- This increase could generate approximately $3.7 billion toward closing the budget deficit.
- Unlike the millionaire income tax, a property tax hike can be enacted with City Council approval and does not require Albany’s sign‑off.
Mamdani positions this as a fallback option if the state refuses to adopt higher taxes on high‑income individuals and corporations. In practice, however, it is the lever that is actually within reach.
Why Property Taxes Get Everyone’s Attention
In real estate, even the suggestion of higher carrying costs gets people’s attention. Property taxes are not just another line on a spreadsheet; they influence:
- Buyer and seller psychology
- Pricing decisions
- Investment appetite
- Rent levels over time
And it is not just homeowners who are affected.
- Renters: While renters do not pay property taxes directly, landlords do. Over time, higher expenses typically get reflected in rent—particularly in free‑market rentals.
- Commercial tenants: Office, retail, and other commercial properties would see higher tax bills, which often get passed through to the businesses occupying them, and eventually to consumers.
There is no neat, isolated pocket of the market that absorbs a property tax increase alone. The effects ripple outward, touching many of the very people the policy is ostensibly designed to protect.
Who Really Feels a Property Tax Hike?
New York’s property tax system is famously complex—and widely regarded as inequitable. Because of how assessments and classifications work, tax increases are not felt evenly.
Critics of Mamdani’s proposal argue that:
- Tax hikes can hit middle‑income and marginal neighborhoods harder than ultra‑wealthy areas, especially where values do not appreciate as quickly.
- Homeowners in these neighborhoods may feel the strain more acutely than owners of high‑value properties in fast‑rising markets.
This stands in tension with the mayor’s stated goal of “taxing the rich” and making New York more affordable for everyone else. A broad‑based property tax hike does not surgically target only the top of the market. It touches a wide range of owners and, indirectly, renters and small businesses.
Political Pushback and the Odds of Passage
Unsurprisingly, the proposal has drawn significant pushback.
- Some City Council members and the Queens Borough President have already called the 9.5% increase a “non‑starter,” citing the potential impact on middle‑income homeowners and communities of color.
- Others are urging a focus on broader property tax reform, pointing to Mamdani’s own campaign promises to simplify and rationalize New York’s complicated system.
Comprehensive reform could, in theory, make the system more equitable over time. But it is not something that can be designed, negotiated, and implemented in a single budget cycle—or even a single year.
In the near term, a large, across‑the‑board tax hike remains a difficult sell.
Is This Policy—or Negotiating Leverage?
Property taxes are politically sensitive precisely because they are broad‑based and visible. They do not quietly adjust behind the scenes. Bills arrive in the mail. Escrow accounts are recalculated. Rent renewals reflect higher costs.
That visibility cuts both ways:
- It makes tax hikes unpopular with a wide range of voters, not just the wealthy.
- It gives policymakers a very public bargaining chip.
For those reasons, it is reasonable to view the property tax proposal not only as a concrete option, but also as negotiating leverage in a broader conversation. It creates pressure to:
- Revisit spending priorities contributing to the deficit.
- Explore alternative revenue sources.
- Push Albany to engage more seriously on income tax and other tools.
As in any negotiation, the eventual outcome is likely to involve some give and some take: adjustments to spending, a mix of smaller revenue measures, and possibly more modest changes to specific tax categories.
What This Means for New Yorkers Right Now
For homeowners, investors, and renters, a few practical points are worth keeping in mind:
- Nothing is final yet. Both the millionaire tax and the 9.5% property tax increase are proposals, not done deals.
- Carrying costs matter. Even the discussion of higher property taxes affects sentiment, especially among buyers carefully modeling monthly costs.
- Markets are psychological. Perception—about affordability, policy direction, and political stability—can influence when people choose to buy, sell, or sit on the sidelines.
If you are considering a purchase or sale in this environment, it is important to look beyond the headlines and understand how potential changes could (or could not) impact your specific building, tax class, and price point.
If you would like to talk through how these proposals might intersect with your real estate plans—or what scenarios are most realistic based on current politics and market data—I am always happy to discuss it. In a city like New York, tax policy, market psychology, and real estate are more connected than they might appear.
