Where to renew your Missouri plate and what you'll need

You renew your Missouri license plate through your county's license office, not online and not through the mail for most situations. You'll need to visit in person with your current registration card, proof of a current Missouri vehicle inspection (Form 108), and proof that your vehicle's property tax is paid. Some counties accept payment by mail if you meet specific conditions — mainly if your plate hasn't expired yet — but the standard route is a visit to your local office.

The address and hours for your county's license office appear on the Missouri Secretary of State website under "License Offices by County." Each county runs its own office independently, so wait times and exact requirements can differ. Call ahead if you're unsure whether you need an inspection or have questions about property tax documentation.

Key Takeaways

  • Missouri license plate renewal requires an in-person visit to your county's license office with your registration card, current vehicle inspection form, and proof of paid property tax.
  • Your vehicle must pass a Missouri safety inspection (Form 108) within the 12 months before your plate expires, or you cannot renew.
  • The renewal fee varies by county and vehicle type, so contact your local office for the exact cost before you go.
  • If your plate has already expired, you must renew in person; mail renewal is only available if your plate is still valid.
  • Your new plate is valid for one or two years depending on your vehicle type and county, and the expiration date appears on your registration card.

What the Missouri vehicle inspection requires

Before you can renew your plate, your vehicle must have passed a Missouri safety inspection within the 12 months before your renewal date. This is Form 108, and it's performed by any authorized inspection station in Missouri — typically independent mechanics, tire shops, or dealerships. The inspection checks your brakes, lights, windshield wipers, horn, steering, and seat belts. It does not check emissions or smog.

The inspection costs between $10 and $25 depending on the station. Once you pass, the station gives you a signed Form 108. Bring this form to your county license office when you renew. If your inspection expired more than 12 months ago, you'll need a new one before the license office will process your renewal.

Property tax and registration requirements

Missouri requires proof that your vehicle's property tax is current before you can renew your plate. This is a county tax, not a state tax, and the amount and rules vary by county. Your county assessor's office handles property tax on vehicles. If you're unsure whether your tax is paid, contact your county assessor directly — they can tell you the status in one call.

Bring documentation showing your tax is paid. This might be a receipt from your assessor's office, a tax bill marked paid, or a letter from the assessor confirming your account is current. If you lease your vehicle, the leasing company typically handles property tax, so ask them for proof before you go to the license office.

Renewal fees and how long your new plate lasts

The renewal fee depends on your vehicle type and your county. Passenger vehicles typically cost less than commercial vehicles or trucks. Contact your county's license office for the exact fee — it's the fastest way to know what to bring. Most offices accept cash, check, and card, but confirm payment methods when you call.

Your new plate is valid for either one or two years. The length depends on your vehicle type and your county's rules. Your registration card will show the new expiration date. Mark it on your calendar so you know when to renew again.

When you can renew by mail instead of in person

A few Missouri counties allow mail renewal, but only if your current plate has not yet expired. You'll need to contact your county's license office to ask whether they offer this option and what documents to send. Generally, you'd mail your registration card, the inspection form, proof of paid property tax, and a check for the renewal fee.

Mail renewal takes longer than in-person renewal — typically two to four weeks — so don't wait until your plate is about to expire. If your plate has already expired, you must renew in person at your county office.

What to do if your plate has already expired

If your plate expired, you cannot legally drive the vehicle on public roads in Missouri. You must renew in person at your county's license office. Bring your expired registration card, a current inspection form, and proof of paid property tax. The office will process your renewal the same way as a timely renewal, but you may face a late fee depending on how long the plate has been expired.

Some counties charge a penalty for late renewal. Ask about this when you call to confirm what documents you need. Once you renew, your new plate is valid from the date you renew, not from the date it expired.

Frequently Asked Questions

Can I renew my Missouri plate online?

No. Missouri does not offer online plate renewal. You must renew in person at your county's license office, or by mail if your county offers that option and your plate hasn't expired yet. Contact your county office to ask whether mail renewal is available in your area.

What happens if I drive with an expired plate?

Driving with an expired Missouri plate is illegal and can result in a traffic citation and fine. If you're pulled over, you'll be cited. Renew your plate as soon as possible. If your plate expired recently, explain the situation to the officer — some may issue a warning if you're in the process of renewing.

Do I need a new inspection every year?

No. Your inspection is valid for 12 months from the date it's performed. If your plate expires within that 12-month window, you can renew using the same inspection. If more than 12 months have passed since your inspection, you need a new one before you can renew your plate.

What if I move to a different county in Missouri?

You'll renew your plate through your new county's license office. Bring your current registration card, inspection form, and proof of property tax paid in your new county. Your new county will issue a new plate with their county code on it.

How do I find my county's license office?

Visit the Missouri Secretary of State website and search for "License Offices by County." The site lists the address, phone number, and hours for every county office. Call ahead to confirm hours and ask about any documents specific to your situation.
