Ga. Code § 48-5-101
Each elected or appointed tax receiver before entering on the duties of his office shall take and subscribe to the following oath in addition to the oath required of all civil officers:
"I swear that I will truly and faithfully perform the duties of receiver of returns of taxable property, or of persons or things specially taxed in the county to which I am appointed, as required of me by the laws, and will before receiving returns carefully examine each, and will to the best of my ability carry out all the requirements made upon me by the tax laws. So help me God."
At the time he takes the oath, the tax receiver shall give bond and security in a sum equal to one-fourth of the amount of the state tax supposed to be due from the county for the year in which he gives bond. No tax receiver shall be required to give a bond exceeding $10,000.00. The amount of the bond shall be determined by the commissioner before being sent out to the several counties.
