Upon receipt of a written response, the Department must contact the garnishee and schedule a conference to discuss the response or inform the garnishee of the Department's position concerning the response. If the Department does not agree with the garnishee on the garnishee's liability, the Department may proceed to enforce the garnishee's liability for the tax by sending the garnishee a notice of proposed assessment in accordance with G.S. 105-241.9, including any penalties imposed in this Article. If the garnishee does not file a response to the notice of garnishment within the time set in this subsection and fails to comply with the notice, the garnishee is subject to the penalties imposed in this Article.
