(a) Once the Tax Collector completes an examination authorized by Section ___-555 and a written notice of the determination of a deficiency has been issued to the taxpayer pursuant to Section ___-545(a) or ___-555(f), the taxpayer's liability for the time period subjected to the examination is fixed and determined, and no additional audit or examination may be conducted by the Tax Collector with respect to such time period except under the following circumstances.
