The Assessment Department is responsible for discovering, identifying, listing and valuing all tangible properties (over 9,000 parcels) within the jurisdiction of the Incorporated Village of Hempstead. These responsibilities include maintaining all assessment inquiries, updating ownership, billing addresses, assessment values, classification, and various non-taxable exemptions as they occur during the tax year to produce a tentative assessment roll for review and a final roll for budget and tax levy purposes.

The Assessment Roll is finalized on April 1st. A State report is submitted each year to the New York State Office of Real Property to create Equalization and Residential Assessment ratios that are used to calculate property values. More than half of the Village’s revenue is generated by the Assessment Department.
