Grievance Day?
A tentative assessment roll is filed on May 1 of each year in the Town Clerk’s Office, based on any new construction to any property you claim ownership of. A final assessment roll is filed in the same office on July 1.
Grievance Day, held on the fourth (4th) Tuesday in May from 5pm to 9pm at the Mt. Morris Town Hall, is a forum for disputing the tentative assessment roll before the final assessment roll is filed.
Grievance forms may be obtained from the Town Assessor’s Office and must be filed by the close of Grievance Day.
Making and Updating Assessments?
Any addition to any property you claim ownership of is considered new construction. Common forms of new construction include: homes, porches, garages, barns, in-ground pools, etc.
New construction is valued as of the taxable status date in the year construction begins.
Market updates (or Revaluations) occur every four (4) years. The next update will occur on the 2018 assessment roll.
Change of Address?
The Town Assessor’s Office must be notified if you undergo a change of address. Please contact our office at 585-658-9820.
