In the case of such delinquency or failure to file, the licensee's license shall be suspended within ninety days after notice of such delinquency or failure to file, unless the director of revenue verifies that such delinquency or failure has been remedied or arrangements have been made to achieve such remedy. The director of revenue shall, within ten business days of notification to the governmental entity issuing the professional license that the delinquency has been remedied or arrangements have been made to remedy such delinquency, send written notification to the licensee that the delinquency has been remedied. Tax liability paid in protest or reasonably founded disputes with such liability shall be considered paid for the purposes of this section.
