(c) When the board makes an assessment as provided in Section 9-17-106, the board shall notify the person by registered or certified mail of the amount of the assessment and shall notify the person to appear at a hearing of the board at the board office on a day named not less than 20 days from date of the notice to show cause why the assessment should not be final. The appearance may be by an agent or attorney. If no response is made on or before the date of the hearing, or if the response is not sufficient in the judgment of the board, the assessment shall be made final in the amount originally fixed or in any amount determined by the board to be correct. The board shall notify the person of the final assessment. A notice by the United States mail, addressed to the last known place of business, shall be sufficient. Any person who has duly appeared and protested an assessment may appeal the final assessment of the board. A hearing on the appeal shall be held at a time and place designated by the board. No appeal shall lie in cases if the person has failed to appear and protest.
Any assessment made by the board shall be deemed correct, prima facie, on appeal.
