Applications must be received in office by Friday March 20, 2026 12:00pm. The completed form should be returned to the Board of Assessment Appeals, c/o Assessor's Office, 1 Central Square, Plainville, CT 06062. The Board of Assessment Appeals meets in March to hear appeals. The Board will  notify all appellants who filed an appeal form on or before March 26th, of the date, time, and place of the appeal hearing. The Board of Assessment Appeals has the power to increase or to reduce assessments. Any change of an assessment by the Board of Assessment Appeals will take affect on the tax bill that comes out in July.
