(1) After making all reasonable efforts to collect unpaid contributions, assessments under 39-51-404, and penalties and interest, or overpaid benefits and penalties under 39-51-3206, the department may determine a debt to be uncollectible. Upon determining that a debt is uncollectible, the department may transfer the debt to the department of revenue for collection as provided in 17-4-104.
(2) Subject to approval by the department, reasonable fees or costs of collection incurred by the department of revenue may be added to the amount of the debt, including added fees or costs. The debtor is liable for repayment of the amount of the debt plus fees or costs added pursuant to this subsection. All money collected must be returned to the department to be applied to the debt, except that all fees or costs collected must be retained by the department of revenue. If less than the full amount of the debt is collected, the department of revenue shall retain only a proportionate share of the collection fees or costs.
