The Board of Assessment Review meets annually on Grievance Day, the fourth Tuesday in May. If a member of the community decides to file for an assessment reduction, they should mail or deliver a complaint form to the Town of Hanover Assessor's Office so that it arrives on or before Grievance Day. If mailing, certified mail would be best. If you mail the form, even if it is postmarked on or before Grievance Day, it is deemed to be late if it does not arrive by Grievance Day. Ideally, the form should arrive at least four business days before Grievance Day. Otherwise, the assessor can obtain an adjournment to have time to prepare a response to your complaint.
