S.C. Code § 12-45-120
If, after the return of any personal tax by any county treasurer as delinquent, the county treasurer shall know or be informed that the person against whom it is charged resides in some other county in this State or has property or debts due him therein, he shall make out and forward to the treasurer of such other county a certified statement of the name of the person against whom such taxes are charged, the value of the property on which such taxes were levied, the amount of the taxes and penalties assessed thereon and that they are delinquent, and to the aggregate of such taxes and penalties he shall add twenty-five percent as collection fees. Upon the receipt of such certificate the treasurer of such other county shall collect such delinquent taxes and penalties, with the twenty-five percent collection fees as provided in this section, for which purpose he shall have all rights, powers and remedies conferred upon the treasurer of the county in which such taxes were assessed and be allowed the same fees for distraint and sale of property as if such taxes had been levied in his own county and, upon collection made, may retain one-half of such twenty-five percent collection fees, and shall transmit the balance collected by him to the treasurer of the county from whom he received such certified statement by mail. But if the treasurer to whom any such statement is sent cannot collect the amount therein named, or any part thereof, he shall return such duplicate, so endorsed, with reasons for such noncollection.
