(a) Any person who has received any sum as benefits under this chapter while any conditions for the receipt of benefits imposed by this chapter were not fulfilled or while the person was disqualified from receiving benefits shall, in the discretion of the Commissioner, either be liable to have such sums deducted from any future benefits payable to such person under this chapter, no single deduction to exceed 50 percent of the amount of the payment from which such deduction is made, or shall be liable to repay the Commissioner for the Unemployment Compensation Fund a sum equal to the amount so received by him. Such sum shall be collectable in the manner provided by law for the collection of debts or any other method of collection specifically authorized by this chapter.

(b) For the purpose of collecting overpaid benefits when the individual who owes the payment resides or is employed outside the State of Georgia, the Commissioner may enter into an agreement with one or more private persons, companies, associations, or corporations providing debt collection services; provided, however, the Commissioner shall retain legal responsibility and authority for the collection of overpayments of benefits and any debt collection agency shall function merely as an agent of the Commissioner for this purpose. The agreement may provide, at the discretion of the Commissioner, the rate of payment and the manner in which compensation for services shall be paid. The Commissioner shall provide the necessary information for the contractor to fulfill its obligations under the agreement. Any funds recovered shall be transmitted promptly to the Commissioner for deposit into the Unemployment Trust Fund.

(c) The Commissioner may waive the repayment of an overpayment of benefits if the Commissioner determines such repayment to be inequitable. If any person receives such overpayment because of false representations or willful failure to disclose a material fact by such individual, inequitability shall not be a consideration and the person shall be required to repay the entire overpayment; provided, however, that penalty and interest accrued on the overpayment are subject to waiver if the Commissioner determines such waiver to be in the best interest of the state.

(d) Any person who has received any sum as benefits under this chapter and is subsequently awarded or receives back wages from any employer for all or any portion of the same period of time for which such person has received such benefits shall be liable to repay a sum equal to the benefits paid during the period for which such back wages were awarded, as follows:

(1) An employer shall be authorized to deduct from an award of back wages the amount of unemployment benefits received by such person under this chapter with respect to the same period of time. The employer shall remit the amount deducted to the Commissioner for the Unemployment Compensation Fund. Upon receipt of such payment the Commissioner shall then make appropriate adjustments in the unemployment contributions experience rating account of the employer as otherwise provided in this chapter; and

(2) If the employer is a governmental entity or nonprofit organization that has elected to make payments in lieu of contributions in accordance with Code Section 34-8-158 and the employee is subsequently awarded or otherwise receives payment of back wages for any period of time for which the employee received benefits under this chapter, said employer shall be entitled to a setoff against the award of back wages in an amount equal to all benefits paid to the employee during the period for which such back wages are awarded or received.
