The treasurer-collector will assume all powers, duties, responsibilities, and liabilities previously held by the separate offices. The board of selectmen will appoint the treasurer-collector and have authority to remove the officeholder; the board can also set up an employment contract lasting up to three years, contingent on annual budget approvals, which will outline salary, benefits, expenses, and performance criteria. Once enacted, this bill will terminate the current elected positions of treasurer and collector, but incumbents may continue until their terms expire or until the new treasurer-collector is appointed, based on which occurs first. The transition to the appointed office will not affect any existing contracts or liabilities of the former positions. Additionally, all records, property, and equipment belonging to the elected treasurer and collector offices will be transferred to the new treasurer-collector.
