Conn. Gen. Stat. § 12-124a
Authorizes any Connecticut municipality, upon approval by its legislative body (or, in town-meeting towns, the board of selectmen), to abate the property taxes on an owner-occupied residential dwelling that is the owner's primary residence to the extent those taxes exceed eight per cent of the total income from any source of the owner and any other occupant for whom the dwelling is the primary residence, for the preceding calendar year. When abatement is approved, the owner must deliver a recorded reimbursement agreement repaying the abated amount with interest at six per cent per annum (or a rate set by the legislative body); that agreement constitutes a lien on the property that becomes due and payable in full upon sale or transfer of the property or the death of the owner (or the last surviving owner).
