Where to renew your Missouri plates

You can renew your Missouri vehicle registration at your county assessor's office, online through the Missouri Department of Revenue website, or by mail. The online option is the fastest if you have no changes to make to your vehicle or address. The county assessor's office handles renewals in person and can answer questions about your specific vehicle or registration history. Mail renewal works if you prefer not to visit an office or use the internet.

Missouri does not have separate DMV locations like some states — the county assessor handles all registration work. Find your county assessor's office address and hours on the Missouri Department of Revenue website by searching for your county name.

Key Takeaways

  • Missouri sends renewal notices 30 days before your registration expires, and you can renew online, by mail, or in person at your county assessor's office.
  • Online renewal through the Missouri Department of Revenue website is the fastest method and requires your vehicle identification number (VIN), current registration number, and a valid payment method.
  • You must renew before your registration expires to avoid a late fee, and driving with expired plates is illegal in Missouri.
  • If you have unpaid traffic violations, property tax issues, or child support arrears on file, your renewal may be blocked until those are resolved.
  • Renewal fees vary based on your vehicle's weight and age, and Missouri charges a one-time $10 online convenience fee if you renew through the website.

What you need to renew online

To renew through the Missouri Department of Revenue website, have your current registration card, your vehicle's VIN, and a credit or debit card ready. You will enter your vehicle information and confirm your address. The system will calculate your renewal fee based on your vehicle's weight class and age.

Online renewal takes about 10 minutes. You will receive a confirmation email when ready, and your new registration card will arrive by mail within 7 to 10 business days. You can print a temporary registration receipt from the confirmation page if you need proof of renewal before your physical card arrives.

Renewing in person at the county assessor's office

Bring your current registration card, proof of vehicle inspection (if required), and a valid photo ID. Some counties may ask for proof of address, such as a utility bill or lease agreement. Payment methods vary by county — most accept cash, check, and card, but call ahead to confirm.

Wait times at the assessor's office vary by county and time of day. Weekday mornings are typically less crowded than afternoons or Saturdays. You will receive your new registration card on the spot, so you can leave with proof of renewal in hand.

Renewing by mail

Mail renewal requires your renewal notice, a check or money order for the renewal fee, and a signed form. Your renewal notice includes instructions and the address to send materials to. Mail your payment and documents at least two weeks before your registration expires to account for postal delays.

The assessor's office will process your renewal and mail your new registration card back to you. This method takes longer than online or in-person renewal — typically three to four weeks total — so plan accordingly if your registration is expiring soon.

Renewal fees and what affects the cost

Missouri renewal fees depend on your vehicle's weight and age. Passenger vehicles typically cost between $75 and $150 per year, but the exact amount is based on your vehicle's gross vehicle weight rating (GVWR). Trucks, trailers, and commercial vehicles have different fee structures.

If you renew online, add $10 to your total fee as a convenience charge. Late renewal fees explore if you renew after your registration expires — the amount varies but is typically $25 to $50 on top of your regular renewal cost. Some counties may charge additional local fees.

When your renewal may be blocked

Missouri will not process your renewal if you have unpaid traffic violations, outstanding property taxes on the vehicle, or child support arrears on file with the state. You must resolve these issues before you can renew. Contact the court that issued any violations or your local child support enforcement office to find out what you owe and how to pay.

If your vehicle failed its last inspection or you have not completed a required inspection, your renewal will also be blocked. Schedule an inspection at a Missouri-certified inspection station and have the results sent to the assessor's office before you attempt to renew again.

What happens if your registration expires

Driving with expired registration plates is illegal in Missouri and can result in a traffic citation. An officer can stop you for expired plates alone, and you may face a fine. If you are stopped, you must show proof that you have renewed — either your new registration card or a printed confirmation from online renewal.

If your registration has been expired for more than 30 days, you may need to pay a late fee in addition to your regular renewal cost. Some counties also require you to renew in person rather than online if your registration has been expired for an extended period. Contact your county assessor's office to find out the specific rules in your area.

Frequently Asked Questions

How long before my registration expires should I renew?

Missouri sends renewal notices 30 days before expiration, and you can renew at any point after receiving the notice. Renewing as soon as you get the notice gives you the most time to receive your new card by mail and avoids the risk of driving with expired plates.

Can I renew my registration if I just bought the vehicle?

If you recently purchased the vehicle, you need to transfer the title and registration into your name first. You cannot renew someone else's registration. Contact your county assessor's office about title transfer, which must be completed before renewal.

What if I moved to a different county in Missouri?

You can renew online or by mail without changing counties, but if you want to update your address with the new county assessor, you will need to visit in person or contact the assessor's office. Your registration will still be valid if you renew before it expires, even if your address is not current.

Do I need a vehicle inspection to renew my registration?

Missouri requires a safety inspection every two years for most vehicles. If your inspection is due, you must complete it before renewing. Your renewal notice will indicate whether an inspection is required. Schedule the inspection at any Missouri-certified station and have results sent to the assessor's office.

What if I lose my renewal notice?

You do not need the notice to renew online or in person — you can renew using your VIN and current registration number. If you are renewing by mail, contact your county assessor's office and ask them to send a duplicate notice or provide the renewal fee amount.
