The first three years' fees may not be refunded. A refund will be issued for the unused portion of a registration (full year increments only). All requests for refunds must be submitted in writing. Both plate and certificate must be returned. If the plate is not returned a lost plate statement must be submitted and a fee of five dollars ($5.00) per plate will be deducted. If a registration certificate is not returned a two dollar ($2.00) per registration certificate is charged. If both the plate and certificate are not returned, a refund will be issued only if the registrant pays the lost plate and lost certificate fee, and submits a statement that the credentials have been lost.
All requests for refunds and accompanying documentation must be submitted in numerical sequence by plate number within expiration year, e.g. all 2018 registrations listed, then 2019 registrations, etc. No portion of the fee paid for the 25-year permanent registration may be refunded.
A registrant may not reregister a vehicle in the permanent registration program if any portion of the previous registration was refunded.
