Where to renew your Missouri vehicle registration
You renew your Missouri vehicle registration at your county assessor's office, not at the DMV. Missouri does not have a Department of Motor Vehicles. The county assessor handles registration renewals, title transfers, and plate replacements for your county.
You can renew in person at the assessor's office during business hours, by mail if your county accepts it, or online through the Missouri Secretary of State's website if your county participates in online renewal. Not all 114 Missouri counties offer online renewal yet, so check your county assessor's website first to see what methods are available where you live.
If you do not know your county assessor's office location or hours, search "[your county name] assessor Missouri" or call the Missouri Secretary of State's office at 573-751-4936 to get the phone number for your county.
Key Takeaways
- Missouri vehicle registration renews through your county assessor's office, which sends you a renewal notice in the mail before your registration expires.
- You will need your current registration card, proof of insurance, and a valid ID when you renew in person.
- Online renewal is available in some counties through the Missouri Secretary of State website, but not all counties participate yet.
- Registration renewal fees vary by vehicle weight and county, so ask your assessor's office what the cost will be for your vehicle.
- If you renew late, you may owe a penalty fee in addition to the standard renewal cost.
What documents you need to bring
When you renew in person, bring your current vehicle registration card, a valid photo ID, and proof of current auto insurance. The insurance proof can be a printed declaration page from your insurance company, a digital copy on your phone, or an insurance card.
If your vehicle's information has changed since your last registration — such as a new address, ownership change, or lien holder — bring documentation of that change as well. If you have moved out of state and back to Missouri, or if your vehicle has been out of service, tell the assessor's office when you arrive.
Renewal fees and what affects the cost
Missouri registration renewal fees are based on your vehicle's gross vehicle weight rating (GVWR), not on the vehicle's age or value. A heavier vehicle costs more to renew than a lighter one. Your current registration card lists your vehicle's GVWR.
Fees also vary slightly by county because each county sets its own assessment fee in addition to the state fee. Call your county assessor's office or check their website to learn the exact renewal cost for your vehicle before you go in. If you renew online, the cost will be shown before you complete the transaction.
If your registration has already expired, you will owe a late penalty in addition to the renewal fee. The penalty amount depends on how long your registration has been expired. Renewing as soon as possible after expiration keeps the penalty as low as possible.
Renewing online through Missouri Secretary of State
Some Missouri counties allow online registration renewal through the Missouri Secretary of State website. To use online renewal, go to sos.mo.gov, find the vehicle registration section, and enter your vehicle identification number (VIN) and current registration number. The system will show you whether your county participates in online renewal.
Online renewal works only if your registration information has not changed, your vehicle has no open liens, and you have no outstanding violations or tickets. If any of those conditions do not explore to you, you will need to renew in person at your county assessor's office instead.
When you renew online, you will receive your new registration card by mail within one to two weeks. You can print a temporary registration receipt to carry in your vehicle until the physical card arrives.
Renewing by mail
Some Missouri counties accept renewal applications by mail. Contact your county assessor's office to ask whether mail renewal is available in your county and what documents they require you to send.
If your county accepts mail renewal, you will typically need to send your current registration card, a check or money order for the renewal fee, and proof of insurance. Include a note with your name, address, and phone number so the assessor's office can contact you if they have questions.
Mail renewal takes longer than in-person or online renewal — usually two to three weeks for processing plus mail delivery time. If your registration is expiring soon, in-person or online renewal is faster.
What happens if your registration expires
Driving with an expired registration is a violation in Missouri. If you are stopped by law enforcement, you can be cited and fined. The fine amount varies but typically starts at $100 or more.
An expired registration also means your vehicle is not legally registered to drive on public roads. If you are involved in an accident while your registration is expired, your insurance may deny a claim. Renew your registration before the expiration date shown on your current card to avoid these consequences.
If your registration has been expired for more than a few months, your county assessor's office may require you to renew in person rather than by mail or online. Call ahead to confirm what they will accept.
License plate replacement during renewal
Your license plate does not automatically renew when your registration renews. You keep the same plate as long as it is in good condition. However, if your plate is damaged, faded, or missing, you can request a replacement plate when you renew your registration.
Replacement plates cost extra — typically $10 to $15 depending on your county — on top of your registration renewal fee. Tell the assessor's office staff that you need a replacement plate when you renew, and they will add the cost to your bill. Your new plate will arrive by mail within two to three weeks.
If your plate is stolen or lost before your registration renewal date, you can request a replacement plate at any time by visiting your county assessor's office. You do not have to wait until renewal.
Frequently Asked Questions
When should I renew my registration?
Missouri sends renewal notices by mail about 30 days before your registration expires. Renew as soon as you receive the notice. You can renew up to 30 days before your expiration date. Renewing early means you will not accidentally drive with an expired registration.
What if I moved to a different Missouri county?
You can renew your registration at your new county assessor's office. Bring your current registration card and proof of your new address, such as a utility bill or lease. Your registration will transfer to the new county without penalty.
Can I renew if my vehicle has a lien on it?
Yes, but the lien holder's name must be listed on your registration. If you are renewing in person, bring your current registration card showing the lien holder. If you are renewing online, the system will tell you if there is a lien and whether online renewal is available for your vehicle.
What if I lost my registration card?
You can still renew. Bring your vehicle's VIN, proof of insurance, and a valid ID to your county assessor's office. The staff will look up your registration information in their system and process your renewal. You will receive a new registration card by mail.
Do I need to pass an inspection before I renew?
Missouri does not require vehicle safety inspections for registration renewal. You do not need to pass an inspection to renew your registration. However, some counties may require an emissions test for certain vehicles — ask your assessor's office whether this applies to you.
