What is the estate tax proposal Mamdani sent to state lawmakers?

According to Bloomberg, the proposal would slash the New York State estate tax exemption threshold by almost 90%, from the current $7.1 million limit to $750,000, and raise the top rate from 16% to 50%. It was among nearly a dozen revenue raising ideas in a memo Mamdani's office circulated to state lawmakers negotiating the state budget. As of this March 2026 report it was a proposal, not law.

Why is the city asking for this?

Mamdani is facing a $5.4 billion city budget deficit for the fiscal year beginning July 1 and is seeking help from the state legislature to close the gap. Supporters of higher taxes on large estates argue that the state should raise revenue from those with the most assets before cutting services or raising other taxes.

How high could the combined death tax rate go?

According to Americans for Tax Reform, combined with the federal estate tax rate of 40% and after accounting for deductibility, New Yorkers would face a combined federal and state rate of up to 70%, which the group says would be the highest in the world. A $750,000 threshold would also be the lowest in the United States among the dozen states that impose a separate state estate tax.

Would this reach middle class homeowners?

At $750,000, the threshold would capture a significant portion of middle class homeowners. A typical single family home on Staten Island or a two family home in Brooklyn can easily exceed $750,000 in value, and retirement accounts, life insurance and other assets count toward the total. Social media users and housing advocates have raised concerns that families could be forced to sell inherited homes to cover the tax. Whether that happens would depend on the final law and on how much liquid cash an estate holds.

What else is in the tax package, and where does the budget stand?

The estate tax idea comes on top of other proposals from Mamdani's first 3 months in office, including a roughly 10% property tax increase affecting over 3 million residential units, an expanded mansion tax, a higher city corporate tax rate, a cut to the Pass Through Entity Tax credit from 100% to 75%, and eliminating a sales tax exemption on precious metals. The state Senate and Assembly included versions of many of these in their one house budget resolutions. Governor Hochul has said she will not support raising income taxes in an election year, and her position on the estate tax specifically had not been stated. Negotiations were expected to run through April with a target of April 1, 2026.

What does this mean for Staten Island and Brooklyn homeowners?

Homeowners with a house worth more than $750,000, plus other assets, are the ones who would first feel a lower threshold, and that describes many Staten Island single family and Brooklyn two family owners. Critics, including a Washington Post opinion piece and former Deputy Mayor Randy Mastro, oppose the plan, while the city says it needs the revenue. Owners who want to understand their own exposure can review their estate plan with an attorney or tax professional. This is general information, not legal or tax advice.
