## Property Tax History

The FY2026/27 figure is a carried-forward estimate, calculated with an earlier year's published rate. The City Council adopted FY2026/27 rates in June 2026, but they may still be revised under a later State law, and this table has not yet been updated with a final FY2026/27 rate. Every rate without the Estimated marker is the published rate for its year.

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.

Assessed and billable values are from the New York City Department of Finance assessment roll for tax lot 1014500008. The City determines them for tax purposes; they are not an appraisal or an estimate of market value. Property tax is calculated from NYC Department of Finance assessment data, including recorded exemptions and abatements where applicable. Actual tax bills and a future buyer's taxes may differ. Tax classes and rates are set annually and can change.
