Conn. Gen. Stat. § 7-576h
A designated tier IV municipality shall not enact a property tax levy in its annual budget that is more than three per cent greater than the property tax levy contained in its annual budget for the prior fiscal year. The secretary shall develop such procedures and guidelines as may be needed to assist in the implementation of such property tax levy limitation. Any designated tier II, III or IV municipality may apply to the Municipal Accountability Review Board for exceptions to such property tax levy limitation. Factors to be considered by such board in approving or disapproving such exception shall include the need to address critical matters impacting the health and welfare of the citizens, funding needed to reduce a municipality's long-term obligations and the implementation of court orders or legal settlements.
