Tax Assessing Information
The tax assessing agent for the Town of Deer Isle holds office hours one day each month, usually on the third Wednesday. If you have questions concerning your tax assessment, please call the Town Office at (207)348-6060 to schedule an appointment with the assessing agent. Appointments are in person at the Town Office. Alternatively, you can call in and speak to the assessor but you must make an appointment and you are responsible to initiate the call at the appropriate time.
If you prefer to make monthly payments on your property taxes and you do not owe back taxes, join our tax club. Each January the Treasurer/Tax Collector's Office will send you a payment book with estimated monthly payments based on the previous years' taxes. Tax Club members have from January to December to pay off their taxes with no interest. Simply mail in your monthly payment stub with your check or drop it off at the Town Office.
