Are you wanting to transfer the remaining registration credit to another vehicle that you need to register?
I wasn't wanting to transfer the credit that way.  I was not aware that I could, but, since you said that it is possible to transfer the remaining registration credit to another vehicle, I might wait as I am about to purchase my husband a new car.
When you surrender your vehicle plates to the DMV, you may be eligible to transfer the remaining registration credit to another vehicle you want to register, or get a refund for the registration fee.  You get a refund or registration transfer credit for your vehicle plate fee, title certificate fee and any other fee or tax that you paid when you registered the vehicle.
There is something more about the referable amounts of DMV. So what is the county use tax table?
