O.C.G.A. § 34-8-163 (2019)

(a) Except as provided in subsection (c) of this Code section, an employing unit liable under this chapter must apply in writing to the Commissioner prior to April 30 in order to terminate liability. If the Commissioner finds that such employer did not, during the preceding calendar year, have sufficient employment or sufficient payroll to be considered an employer under this chapter, or was not otherwise subject to this chapter, then such coverage shall be terminated as of January 1 of such completed calendar year. Wage credits of any individual may not be decreased as a result of the employer being terminated. For the purpose of this Code section, two or more employing units who are predecessors or successors in a business or organization shall be treated as a single employing unit.

(b) The Commissioner may terminate the liability of an employer without written application of the employer when such employer did not have sufficient employment or sufficient payroll during a calendar year to be considered an employer under this chapter.

(c) All types of elective coverage as provided in paragraph (7) of Code Section 34-8-33 may be terminated in the discretion of the Commissioner at any time subsequent to the first two-year period.
