S.C. Code Ann. § 23-6-50
The director shall annually cause the department to be audited. The audit must be conducted by a certified public accountant or firm of certified public accountants to be selected by the State Auditor. The designated accountant or firm of accountants shall issue audited financial statements in accordance with generally accepted accounting principles, and such financial statements shall be made available annually by October fifteenth to the General Assembly. The costs and expenses of the audit must be paid by the department out of its funds.
Notwithstanding any other provision of law, all revenue generated by the department from the sale of vehicles, various equipment, less the cost of disposition incurred by the Budget and Control Board Division of Operations, gasoline and insurance claims, during the prior fiscal year may be retained and carried forward into the current fiscal year and expended for the purpose of purchasing like items. Any unexpended balance on June 30 of the prior fiscal year authorized to be expended or used for any federal grant program may be retained and carried forward to the current fiscal year and used for matching committed or unanticipated grant funds, or both.
