Mayor Mamdani pushes back deadline for pied-à-terre tax exemptions

Mayor Zohran Mamdani said the city will grant property owners an additional month to file appeals against the newly enacted pied-à-terre tax, setting the new deadline at Sept. 18. Previously, owners of homes valued over $5 million had until Aug. 21, and owners of co-ops and condos over $1 million until Aug. 24, to request exemptions. The extension comes after the Department of Finance mailed roughly 17,000 notices indicating potential five-figure liabilities, a figure that dwarfs the 10,000-13,000 non-primary residences originally projected to be taxed.

Council Minority Leader David Carr condemned the original schedule as inadequate, likening it to a “train wreck” and urging ample time for appeals. The tax, passed by the Democratic-controlled state Legislature and signed by Governor Kathy Hochul, is expected to raise about $500 million for New York City’s budget. Mamdani, who championed the levy, framed the deadline shift as the minimum corrective step the administration can take.
