My property is overvalued and my taxes are too high. How do I grieve my assessment / lower my taxes?
Each year, property owners can file a grievance to lower the assessed value of their home if they have additional information that could lead to a more accurate assessment.

Grievance Day is held on the third Tuesday in May. During the week prior, residents may go to the Assessor’s Office in Town Hall, or to the town’s website for assistance with completing the grievance application and/or to help understand how particular assessments were determined.

Appointments with the Assessor’s Office can be made by calling 631-283-6020.

Office Hours: 8:30 a.m. to 4 p.m.
