Trump Floats Federal Action To ‘Avert’ Mamdani’s Pied-A-Terre Tax I cover breaking news.Aug 11, 2026, 01:25pm EDTToplinePresident Donald Trump said he was looking into ways to “avert” the implementation of New York City’s pied-a-terre tax—the tax on second homes owned by out-of-state residents that has served as a centerpiece to Mayor Zohran Mamdani’s agenda and proven controversial among some of the city’s wealthiest residents.Trump raged against the tax on second homes for out-of-state residents pushed by New York City Mayor Zohran Mamdani.Getty ImagesKey FactsIn a post on Truth Social, Trump claimed without offering evidence the tax is costing New York a “fortune,” while also claiming, again without offering evidence, the amount levied from the tax would be “very little compared to to [sic] the TAXES PAID by the tens of thousands of people who are fleeing the City, never to return.”Trump’s statement comes one day after a judge on Staten Island blocked the new tax after a lawsuit was brought by homeowners—although that order was stayed just hours later after the Mamdani administration appealed the ruling.It is unclear what federal authority Trump could attempt to use to block a local tax law.This is a breaking story and will be updated.LOADING VIDEO PLAYER...FORBES’ FEATURED Video
