The administrative penalty is $15 if plates are not renewed on time. You may renew online, at a BMV Connect Kiosk, or visit a branch.
Another option is to renew over the phone. If renewing your registration over the phone, you will need the access code provided on the registration renewal reminder notice you received in the mail. If choosing to renew by mail, if the envelope requesting the renewal is postmarked by the expiration date, the late fee will not be assessed
