The Town of Hartford’s Sole Assessor is appointed by the Town Board.


March 1st – Taxable Status Date
The Assessor is required by New York State Law to value property as it is on this date. A partially completed building will receive a partial assessment based on its estimated percentage of completion as of March 1. If you suffer a loss to your property (ex: fire, demolition) after this date you will see no reduction for that loss on forthcoming roll. Exemption forms must be filed by this date also.

May 1st – Tentative Roll
The tentative roll is a list, in alphabetical order, of all Real Property in the Town as of Taxable Status Date. Some of the information on these parcels include owner’s names, locations, acreage, property class, assessed values and exemptions. Tentative Roll is filed with the Town Clerk and is available for viewing.

Contact the Assessor prior to Grievance Day with any complaints regarding your assessment. All complaints about assessments and exemptions must be received no later than this day.

The Board of Assessment Review begins its hearings on this date at the Hartford Town Hall with times posted.
