The City has not published the official FY2026/27 and FY2025/26 tax rates yet. We calculated the tax for those years using the prior year’s rate, so treat them as an estimate rather than a figure the City has adopted. Every rate without the Estimated marker is the published one.

Tax Assessment is the assessed value on the City’s roll, and it is the figure other listing sites publish. It is not what the bill is calculated on. New York phases assessment changes in gradually for some tax classes, so the City bills the Billable Value shown beside it, less any exemption the owner holds. It usually trails the assessment, and it can sit above it for a few years after an assessment falls.

Where an abatement applies, Property Tax is the amount owed after it. Abatements are granted to the property and do not necessarily transfer to a new owner.

Figures are the New York City Department of Finance assessment roll for tax lot 3050640029. Assessed and billable values are determined by the City for tax purposes and are not an appraisal or an estimate of market value. Tax classes and rates are set annually and can change.
