Phase 1 exposure is the flat surcharge on every unit at or over the line, as if none were a primary residence. It is a ceiling, not a bill.

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. Confirm your own situation with a New York attorney or your accountant. Milton Coste, Licensed Real Estate Associate Broker, Keller Williams NYC, 360 Madison Avenue, 9th Floor, New York, NY 10017.
