I want to know how the refunds are determined and the period in which I should surrender my plates.
I can give you an example of how a refund is determined.
Can I get a refund for the first year of my registration after receiving a refund for the second year?
Yes, but only if you have the unused registration sticker and stub. If so, then you are eligible for the refund of the first year of the registration. You have a maximum of 60 days after the date the registration was made to apply for a refund for the first year of the registration fee.
