You Could Face Fines and Fees
The Florida Department of Motor Vehicles (DMV) requires that you return your license plates when you cancel your vehicle registration. If you fail to do so, you could face fines and fees. The amount of the fines and fees will vary depending on the county in which you live.

In most counties, the fine for failing to return your license plates is $25. However, in some counties, the fine can be as high as $100. In addition to the fine, you may also be charged a fee for the cost of replacing the license plates. The fee for replacing license plates is typically $15.
Your Vehicle Registration May Be Suspended
If you do not return your license plates, the DMV may suspend your vehicle registration. This means that you will not be able to legally drive your vehicle. If you are caught driving with a suspended registration, you could face additional fines and penalties.
You Could Be Arrested
In some cases, you could be arrested for failing to return your license plates. This is because failing to return your license plates is a misdemeanor offense. If you are convicted of a misdemeanor, you could face jail time, fines, and other penalties.
How to Avoid Fines and Penalties
The best way to avoid fines and penalties is to return your license plates to the DMV when you cancel your vehicle registration. You can return your license plates in person at any DMV office or by mail. If you return your license plates by mail, be sure to include your name, address, and vehicle information.
What to Do If You Lose Your License Plates
If you lose your license plates, you should report them to the DMV as soon as possible. You can report lost license plates online, by phone, or in person at any DMV office. Once you have reported your license plates as lost, the DMV will issue you new license plates.
