Free Pied-a-Terre Tax Check: Your Unit’s DOF Market Value

Type the building address and apartment number. The value from the Department of Finance’s July 24, 2026 supplemental roll, the band it falls in and the Phase 1 annual figure show on this page, with no form to fill in first.

Updated October 9, 2026

For a one- to three-family house we show only the lot your address resolves to. No other home is ever listed.

How to read the result

The figure is the DOF market value on the July 24, 2026 supplemental roll. It is not the assessed value printed on a tax bill and it is not a sale price. Condos and co-ops are in range at $1,000,000 and up, houses at $5,000,000 and up, and the band rate applies to the full value. The rates page has every band, and the methodology page explains how the roll is read.

A value over the line shows exposure, not a bill: the surcharge applies only when no one on the statute’s list lives there as a primary residence. If DOF sent you a notice, the deadline is October 13, 2026; the notice page covers what to file.

Weighing keep, lease or sell?

The sell-or-lease calculator sets the annual surcharge against a one-year lease and a sale. I am happy to run it with you using recent sales in your building.

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.
