The owner of a vehicle may, before the vehicle becomes delinquent in any year, turn in the registration plates for a vehicle to the county treasurer of the county where the vehicle is registered. A vehicle eligible for semiannual installments may not be stored until the second semiannual installment is paid. There is no refund of registration fees when placing a vehicle in storage. You may re-register your vehicle at any time in the future with the payment of the full current annual registration fee due at that time. However, if a vehicle was placed in storage any month prior to the expiration of the registration, replacement plates must be issued and replacement plate fee paid.
