Tag registrations are due by your birthday, NOT by the end of the month. You may purchase your tag thirty (30) days before your birthday. Renewal notices are not mailed; however, you may call to have your Registration mailed to you. Business names take a different business schedule–by the first letter of the name. Failure to renew your tag by your birthday or business registration will result in the following penalties: 10% of the ad valorem tax or $5.00–whichever is greater, and 25% of the tag fee or $5.00–whichever is greater. It is your responsibility to renew your vehicle at the appropriate time whether you receive prior notice in the mail or not.
