NYC property owners express anger and confusion over rollout of Mamdani's 'pied-à-terre tax'Many New York City property owners are angry and confused after they received a notice from the city stating they may owe Mayor Mamdani's 'pied-à-terre tax.' Real estate attorney Benjamin Williams said many property owners believe they have been wrongly targeted as the city works to identify luxury second homes. Mayor Mamdani has maintained that the surcharge is intended to target wealthy property owners. Mamdani later defended the administration's rollout of the program, saying property owners have time to work with the city before the surcharge takes effect. The Finance Department's deadline for filing exemption requests is Aug. 24, and the Tax Commission will hear appeals through March.
