Why did New York Mayor Zohran Mamdani publish a list of nearly 1 million homeowners who “may” face his new property-tax surcharge when the city estimates that only 10,000 properties will actually owe it? It may have something to do with the fact that Mamdani wants to raise taxes far higher than Albany Democrats have allowed so far, and he is putting homeowners on notice that they are next.An unapologetic socialist, Mamdani ran for mayor on a promise to redistribute wealth from the rich to everyone else. That included a 2% income tax surcharge on all residents earning more than $1 million a year. Mamdani estimated that the tax would bring in about $3 billion annually.Unfortunately for Mamdani’s socialist ambitions, Gov. Kathy Hochul (D-NY) would not consent to this. She worried, with good reason, that yet another tax on high-income earners would drive even more successful people out of New York at a time when the state is already losing tens of thousands of taxpayers every year. Instead, unfortunately for everyone other than Mamdani and his collectivist colleagues, Hochul agreed to a non-primary-residence tax, sometimes called a pied-a-terre tax, on certain properties. Hochul’s office estimates that the tax will raise $500 million, far short of the $3 billion Mamdani hoped for.
