New York City residents with secondary homes valued at more than $5 million will face a new surcharge, with Mayor Zohran Mamdani stating he is confident the city will collect $500 million from the measure. He made the projection during a Thursday interview on WNYC’s “Who’s Running This Place?,” a show hosted by Brigid Bergin. The tax aims to generate revenue to fund city services, a goal Mamdani described as fulfilling his campaign promise to tax wealthy nonresidents.

The collection target faces hurdles. City Hall data shows the Department of Finance has granted exemptions to more than 8,800 of the roughly 11,000 applications filed. This leaves fewer than 9,000 properties subject to the tax. In April, Comptroller Mark Levine estimated the tax would yield only up to $380 million from about 11,200 homes. The gap between the initial projection and the current exemption count has raised questions among experts about whether the $500 million goal is achievable.

Three legal challenges currently threaten the tax’s implementation. On Wednesday, city attorneys argued against claims from landlords who say the rollout caused mass confusion and require a restart. A separate complaint filed by billionaire Steve Wynn and former Commerce Secretary Wilbur Ross argues the state law discriminates against wealthy nonresidents. Ben Williams, a property tax attorney at Rosenberg & Estis, noted that the city has maintained its revenue projection despite the rising number of exemptions. Williams questioned whether the city would raise the tax rate if it misses the target.

Mamdani also addressed the impact of the tax on local investment. He countered criticism from Nassau County Executive Bruce Blakeman, who has vowed to cancel the surcharge in his campaign for governor. Blakeman argues the tax discourages investment in the city. Mamdani defended the policy by stating the funds will make streets safer and schools stronger. He noted that the surcharge targets secondary homes worth more than $5 million and acknowledged that the policy remains offensive to Blakeman.

The mayor used the interview to discuss his administration’s stance on federal immigration enforcement. He said he is in ongoing conversations with President Donald Trump and Homeland Security Secretary Markwayne Mullin. Mamdani stated his demand is not limited to the case of Oscar Belgal, a 28-year-old Marble Hill resident shot by ICE agents earlier this month. Belgal is currently held in a federal jail in Brooklyn. Mamdani said he wants to end ICE operations in New York City entirely.

Police Commissioner Jessica Tisch and Mamdani have spoken about ensuring the city complies with sanctuary laws, which limit cooperation with federal immigration agents. The mayor said both officials take the matter seriously. He also addressed criticism regarding his education agenda, noting that Chancellor Kamar Samuels was booed last week by parents frustrated with the pace of school integration plans. Mamdani described his goal as transforming public schools into institutions that are safe, rigorous, and integrated.

The mayor, who is campaigning alongside Governor Kathy Hochul, laughed when referencing a clip of Blakeman attacking him. He suggested Blakeman had prepared his criticism in front of a mirror. Mamdani maintained that the revenue from the second home tax will directly benefit working families and public services.
