What to do with Montana plates after moving to Mississippi
The answer can be return, cancel, destroy, recycle, or keep. Follow the reviewed Montana instruction only after the Mississippi registration and insurance handoff are safe.
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.
Cancel the Montana registration with MV60 after the new registration is active
After the destination registration is active, complete Montana MV60 and select permanent cancellation. Every listed owner must consent, and the plates must be removed when they remain in the owner's possession. Keep the signed form and submission proof with the destination registration before treating the old record as closed.
