Where to renew and what you need
You can renew your Missouri license plates at your county assessor's office, online through the Missouri Department of Revenue website, or by mail. The online option is fastest if your vehicle has a clean title and no liens — you can complete it in minutes and your new plates arrive by mail within two weeks. The county assessor's office handles renewals in person and can process them the same day.
Bring your current registration card, proof of insurance, and a valid ID. If your vehicle has a lien, the lienholder must sign off on the renewal, which means you may need to contact your lender first. Missouri does not require a vehicle inspection for standard plate renewal unless your vehicle is over 20 years old or you are renewing after a lapse of more than a year.
The renewal notice arrives in the mail about 60 days before your plates expire. It shows your renewal fee, which depends on your vehicle's weight and age. You do not have to wait for the notice to renew — you can start the process 90 days before expiration.

- Online renewal through the Missouri Department of Revenue is the fastest option and takes about two weeks for plates to arrive by mail.
- Your county assessor's office can renew plates in person the same day you visit, and you need your current registration card, proof of insurance, and a valid ID.
- Mail renewal is available but slower — send your renewal notice and payment to your county assessor's office and allow three to four weeks for processing.
- If your vehicle has a lien, the lienholder must authorize the renewal before you can complete it.
- Renewing before your plates expire keeps you from driving with expired tags, which can result in a traffic stop and a fine.
Online renewal through the Missouri Department of Revenue
Visit the Missouri Department of Revenue's vehicle registration page and select the online renewal option. You will need your registration card number, vehicle identification number (VIN), and the last four digits of your Social Security number or tax ID. The system will verify your information and calculate your renewal fee based on your vehicle's weight.
Online renewal works best if you have no liens on the vehicle and your address and insurance information are current. If the system flags a problem — such as a lien that needs authorization or an insurance lapse — it will tell you what to fix before you can complete the transaction. Payment is by credit card or debit card, and you receive a confirmation number when ready.
Your new plates ship within two weeks. Missouri sends them to the address on file with your registration. If you have moved recently, update your address with the Department of Revenue before renewing online, or your plates will arrive at the old address.
In-person renewal at your county assessor's office
Find your county assessor's office online by searching "[your county] Missouri assessor." Hours vary by county, but most offices are open Monday through Friday during standard business hours. Some larger offices offer Saturday hours. Bring your current registration card, proof of insurance (a photo or digital copy is fine), and a valid driver's license or ID.
The assessor's staff will verify your vehicle information, confirm your insurance, and calculate your fee. If everything is in order, they can issue your new plates on the spot. You drive away with temporary tags and your new permanent plates, or they mail the plates to you if they need to order them. Processing usually takes 15 to 30 minutes.
If your vehicle has a lien, bring written authorization from the lienholder, or ask the assessor's office what form the lender needs to sign. Some lenders can fax authorization directly to the office, which speeds up the process.
Mail renewal and what to expect
Mail your renewal notice, a check or money order for the renewal fee, and a copy of your current proof of insurance to your county assessor's office. Include a note with your phone number in case the office has questions. Mail renewal takes longer than online or in-person — typically three to four weeks from the time the assessor's office receives your envelope.
Use the address printed on your renewal notice. If you have moved and did not receive a notice, contact your county assessor's office for the correct mailing address and ask them to send you a renewal form. Do not send cash through the mail.
Your new plates arrive by mail after the assessor's office processes your payment. If your plates expire before they arrive, you are driving with expired tags, which is why mail renewal is the slowest option and best used only if you renew well before expiration.
Vehicles with liens and special situations
If your vehicle has a lien, the lienholder's name appears on your registration card. You must obtain written authorization from the lender before renewing. Some lenders provide a form; others straightforward sign a letter authorizing the renewal. Contact your lender's customer service line and ask what they need to authorize a plate renewal.
If you are renewing after a lapse — meaning your plates have been expired for more than a year — Missouri may require a vehicle inspection to confirm the vehicle is still roadworthy. Contact your county assessor's office before renewing to find out whether an inspection is needed. If one is required, you can have it done at any Missouri inspection station and bring the inspection report with you when you renew.
Vehicles over 20 years old may have different renewal rules depending on whether they are registered as antique or classic vehicles. If your vehicle falls into this category, ask your assessor's office whether your renewal process differs from standard passenger vehicles.
Renewal fees and what affects the cost
Missouri renewal fees are based on your vehicle's weight, not its age or value. The heavier the vehicle, the higher the fee. Your renewal notice shows the exact amount you owe. Fees typically range from around $50 to $150 per year, but the exact amount depends on your specific vehicle.
If you renew online or by mail, you pay only the renewal fee. If you renew in person at the assessor's office, some counties charge a small processing fee in addition to the renewal fee — usually $5 to $10. Ask about this when you visit or call ahead.
If your vehicle is financed and you have gap insurance or other add-ons through your lender, those do not affect your plate renewal fee. The fee is set by the state and does not change based on your insurance coverage.
What happens if your plates expire
Driving with expired plates is a traffic violation in Missouri. A police officer can stop you for expired tags, and you can receive a fine. The fine amount varies but typically starts around $100 to $200. If you are stopped, you can show the officer your renewal notice as proof that you have started the renewal process, though this does not may provide you will avoid a ticket.
If your plates expire and you have not renewed, renew as soon as you can through any of the three methods above. Online renewal is fastest if you need plates quickly. If you are concerned about driving with expired tags while waiting for new plates to arrive, renew in person at your county assessor's office and ask for temporary tags.
Frequently Asked Questions
Can I renew my plates if I just bought the vehicle?
Yes, but you must first register the vehicle with the Missouri Department of Revenue. You cannot renew plates for a vehicle that is not yet registered. If you just bought the car, register it first at your county assessor's office or online, then renew the plates if they are expiring soon. If the plates are not expiring for several months, you can wait and renew them on the normal schedule.
What if I move to a different county in Missouri?
Update your address with the Missouri Department of Revenue as soon as you move. You do not need new plates when you move within Missouri — your current plates stay valid. However, updating your address ensures your renewal notice and new plates arrive at the correct location. You can update your address online through the Department of Revenue or at any county assessor's office.
Do I need to renew my plates if I sell my vehicle?
No. When you sell your vehicle, notify the Missouri Department of Revenue and provide the buyer's information. Your responsibility for the plates ends when ownership transfers. The new owner must register the vehicle and renew the plates in their name. If you do not report the sale, you may receive renewal notices for a vehicle you no longer own.
How far in advance can I renew my plates?
You can renew up to 90 days before your plates expire. Renewing early is a good idea if you want to avoid the rush near the expiration date or if you prefer to renew online and want time for the new plates to arrive by mail.
What if my renewal notice does not arrive in the mail?
Contact your county assessor's office and ask them to send you a renewal form or tell you the amount you owe. You do not need the notice to renew — it is just a reminder. The assessor's office can look up your vehicle information by VIN or license plate number and provide everything you need to complete the renewal.
