32 V.S.A. § 4873: Interest on installments

All taxes payable in installments may bear interest if the town so votes at a rate not to exceed one percent per month or fraction thereof for the first three months and thereafter one and one-half percent per month or fraction thereof, either from the due date of the last installment or from the due date of each installment. When a town so votes, such vote shall remain in effect until such time as the town rescinds the same by a majority vote of the legal voters present and voting at an annual or special meeting duly warned for such purpose.
