The bill, identified as Substitute House Bill No. 5393 with File No. 411, proposes changes to the process of appealing property tax assessments in Connecticut. It amends subsection (a) of section 12-111 of the general statutes, effective July 1, 2024. The bill outlines the procedure for any person aggrieved by the assessors' actions to appeal to the board of assessment appeals. The appeal must be filed by February twentieth and include specific information such as the property owner's name, description of the property, reason for the appeal, and an estimate of value. The board is required to notify appellants of their hearing date by March first and must send written notification of their final determination within one week of making a decision. The bill also allows the board to adjust the grand list and add assessments for omitted property, with a 25% increase if the property should have been declared.

The bill further specifies conditions under which the assessor can change the gross assessment of a property after the board of assessment appeals has made a determination. The gross assessment can be adjusted to comply with a court order, reflect new construction or damage, correct factual errors, or for other reasons specified by the bill, such as to equalize assessments or comply with a BAA decision that it is necessary. These changes are in addition to the existing reasons for adjustment. The bill prevents assessors from changing the gross assessment prior to the next revaluation unless it falls under the specified reasons. The fiscal impact of the bill is dependent on the changes an assessor would have otherwise made, and there is no state impact noted. The bill was reported favorably by the Committee on Planning and Development.
