Amends GS 153A-199 to authorize boards of commissioners to determine that assessment payments may be made by semiannual payments in addition to annual installment payments authorized under existing law. Allows for the resolution to set the number of installments, with up to 40 semiannual installments or 20 annual installments permitted. Details when semiannual payments may be due, allowing the board to provide that the first installment is due with interest either on (1) the date when property taxes are due, with one installment with interest due on the same date in each successive six-month time period, or (2) 60 days after the date that the assessment roll is confirmed, with future installments and interest due on that same day in each successive six-month time period.
