If you need to supply proof of income or any other supporting information for your exemptions renewals, the deadline is still April 15th. If you have not yet filed your tax return we will need copies of your income statements. Information can be put in the Receiver of Taxes drop box located next to the front doors of the Town Hall. They will forward what you submitted to the Department of Assessment. The 2020 Grievance period has not changed either. The Informal Review period is not extended and has expired.
