The Assessor is the official who estimates the value of the real property, which is converted into an assessment (one component in the calculation of real property taxes).

It is the responsibility of the Assessor to maintain a fair and equitable assessment roll, the document which lists all properties and their assessments within an assessing district. It also lists a property's exemption(s), if any.

The assessment office processes exemption applications, including Enhanced STAR Renewals, Senior Citizens, Veterans, Persons with Disabilities, Non-Profits, Clergy, etc. For more information, please see the exemptions tab.

Please note that all new STAR Applications need to be filed directly with the NYS Department of Taxation and Finance. See the "STAR Registration Info." link in the navigation column.

For more information about the job of the Assessor, please visit the NY State Department of Taxation and Finance's 11-minute YouTube video entitled, "The Job of an Assessor." Their 4-minute video, "About Property Taxes and Assessments," provides a good overview of property taxes and assessments. (links are listed in the navigation column.)

Key assessment dates are the same every year, as follows:

  • The Taxable Status Date (and exemption application deadline) is May 1st
  • The Valuation Date is May 1st (of the current year)
  • The tentative assessment roll is published on June 1st
  • Grievance Day is the 3rd Tuesday in June
  • The final assessment roll is published on August 15th

The current assessment roll is available for public review and can be found on the City's website, as well as in the Assessor's office. Links to copies of historic assessment rolls (2013 to date) can be found in the Assessment Rolls tab on these Assessor webpages.
