Mamdani’s pied-a-terre tax list triggers privacy concerns in NYC

New York City Mayor Mamdani’s administration published a public database listing the names and addresses of property owners who could be subject to the state’s new pied-a-terre tax — a move critics call doxxing and say misaligns with the policy’s targets, as the list includes many non-qualifying properties. City Hall says publication is required by law to identify potentially taxed residences, but the scope appears far broader than expected: about 960,000 residences listed versus an intended 31,000. Revenue projections vary—from roughly $340–$380 million per year (Comptroller) up to $500 million per year (city projection). The list includes celebrities and prominent figures, prompting backlash from lawmakers and business groups who warn it could harm the luxury market and public safety perceptions.
