When transferring your remaining registration to another vehicle, take into consideration that the new registration will expire the same day as the old one, and you can only use the transfer credit for a new original registration, you can't use it for a renewal.
How can I know if am eligible for a refund?
After you surrender your plates, your Receipt FS-6 T indicates if you are eligible for a refund. If you are and you do not request a transfer receipt, your refund will be processed automatically and you'll get it in your mail after some weeks.
Can I still apply for a refund if the registration sticker was attached to the plate?
