More on the NYC pied-a-terre tax
This page is educational and is not legal or tax advice. Rates, thresholds and dates come from NY Tax Law Article 30-C (text of the statute) and the NYC Department of Finance (non-primary residence surcharge page), checked October 9, 2026. Values come from the DOF supplemental market value roll of July 24, 2026 (DOF property assessments). A value on the roll shows exposure, not liability: the roll carries no occupancy information, and DOF says appearing on it does not mean a property is subject to the surcharge.
