What to do with South Dakota plates after moving to Mississippi
The answer can be return, cancel, destroy, recycle, or keep. Follow the reviewed South Dakota 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.
Update the South Dakota record and keep the old plates
After the destination registration is active, update the address in South Dakota's vehicle record through the online portal or your county treasurer. Remove and retain the South Dakota plates; the state describes them as staying with the owner. Keep the address-update confirmation with the new registration.
