What to do with Kansas plates after moving to Mississippi

Complete the replacement record

Apply through the county Tax Collector within 30 days after moving while the prior registration remains valid. Mississippi publishes a $250 penalty in addition to standard late-registration penalties for missing the new-resident deadline.

Maintain Mississippi liability coverage and keep the insurance card in the vehicle. The state notes that proof is required for operation even though registration offices do not enforce it as a filing prerequisite.

Use the Kansas plate return to close the record and claim any refund

After the destination registration is active, take the Kansas plate and registration receipt to the county treasurer's motor-vehicle office in the county where the vehicle was registered. Moving out of state qualifies for a registration and property-tax refund; Kansas calculates it from the date the office receives the plate, so retain the office receipt and refund submission record.
