If a debtor owes a debt to a State agency and the net proceeds credited to the State agency for the debt exceed the amount of the debt, the State agency must send the balance to the debtor. No part of the collection assistance fee retained by the Department may be returned when a debt is owed but it is less than the amount set off.
Interest accrues on the amount of a refund returned to a taxpayer under this subsection in accordance with G.S. 105-241.21. A State agency that returns a refund to a taxpayer under this subsection must pay from the State agency's funds any interest that has accrued since the fifth day after the Department mailed the notice of setoff to the taxpayer.
