If none of the over-the-line units were a primary residence, the Phase 1 surcharge would total about $1,966,993 a year. That is a ceiling: owners who live there, lease for a year or more to a primary-resident tenant, or house an immediate family member owe nothing. See every exemption.
How values spread across the building
Phase 2 sensitivity
From July 1, 2028, Phase 2 moves condos and co-ops to a $5,000,000 threshold and the 0.8%, 1.05% and 1.3% schedule, measured under a new DOF assessed-value system that DOF has not finalized. It is scheduled, not settled. On today’s DOF values, 0 units in this building would sit at or above the $5,000,000 Phase 2 line.
Lease it out
A 12-month arm’s-length lease to a tenant who makes the apartment their primary residence removes the surcharge for that unit. See every exemption and what proves it.
This building has fewer than three leases on the RLS in the last 24 months, so the neighborhood figures below stand in for it.

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.
