For a motor vehicle with a Gross Vehicle Weight (GVW) of 10,000 pounds or less, register the vehicle and receive your license plate from your local county Tax Collector’s office. You will need to register the vehicle in the county where the vehicle is domiciled, or where it is parked (garaged) overnight. For a motor vehicle with a GVW over 10,000 pounds and which travels only in Mississippi, you will register the vehicle at your local county Tax Collector’s office. For a motor vehicle with a GVW over 10,000 pounds and which travels across state boundaries, you will register the vehicle at the Department of Revenue office in Clinton, Mississippi. What should I do to renew my vehicle registration (license plates) if I did not receive a renewal notice in the mail? Please visit your county Tax Collector to complete your renewal. You are responsible for renewing your license plate(s) before the expiration date even if you do not receive a renewal notice. Late penalties will be due if you do not renew the tag within 15 days after the tag’s expiration date.
