Key Dates on Assessment Calendar

Key Dates on Assessment Calendar (2020)


Due to the COVID-19 pandemic, the Town’s scheduled 2020 revaluation will be postponed until the 2021 assessment roll. The Town had previously entered into a cyclical plan with the New York State Office of Real Property Tax Services culminating with a Town-Wide reappraisal reassessment in 2020.  The Town will not implement the revaluation plan for this year, however properties may see assessment adjustments based on such things as physical inventory changes, construction and demolitions.

June 1st thru THIRD TUESDAY in June (time frame to file a grievance): NEW DATES: June 30 – July 21, 2020:   The Board of Assessment Review will convene on the third Tuesday in July (Grievance Day). At this time we are hopeful that the Town can continue to receive grievances by mail as well as in person, as in past years.  For the safety of our residents and staff, an announcement will be made in June if it is necessary to make a change to the location of the “in person” filings.
