Missouri lets you renew your vehicle tags through the mail, online, or in person at your local license office

Missouri's tag renewal system is called Mo Renew, and it's the state's official way to handle registration renewals. You can renew online at dmv.mo.gov, by mail using the renewal notice the state sends you, or by visiting a Missouri Department of Revenue office in person. Most people renew online or by mail because both are faster than waiting in line.

The method you choose depends on what works for your schedule and whether your vehicle qualifies. Some vehicles — like those with liens, out-of-state titles, or certain commercial plates — cannot renew through Mo Renew and must go to an office instead. The state sends renewal notices about 30 days before your tags expire, and that notice contains everything you need to know about which method you can use.

Key Takeaways

  • Missouri sends renewal notices about 30 days before expiration, and you can renew online, by mail, or in person using that notice.
  • Online renewal through dmv.mo.gov is the fastest option and works for most standard passenger vehicles with clear titles.
  • Mail renewal takes longer but requires no login or online account — you fill out the form that came with your notice and send it back with payment.
  • Vehicles with liens, out-of-state titles, or commercial plates must renew in person at a Missouri Department of Revenue office.
  • You can renew up to six months before your tags expire, so you do not have to wait until the last minute.

Renewing online through Mo Renew

Online renewal is the fastest route if your vehicle qualifies. Go to dmv.mo.gov, select the renewal option, and enter your vehicle identification number (VIN) and license plate number. The system will pull up your registration record and show you the renewal fee, which varies based on your vehicle's weight and type.

You will need a valid credit or debit card to pay online. The state charges a convenience fee for online payments — this fee is separate from your registration renewal cost and varies depending on the payment processor. After you submit payment, the state mails your new tags to the address on file, usually within 7 to 10 business days.

Online renewal does not work if your vehicle has a lien, if your title is from another state, if you need to add or remove a vehicle owner, or if your address has changed since your last registration. In those cases, you must renew by mail or in person.

Renewing by mail with your renewal notice

The renewal notice Missouri sends you contains a form you can fill out and mail back. This method works for any vehicle that qualifies for renewal — you do not need an online account or to enter information into a computer. Write a check or money order for the renewal fee (the notice tells you the amount), include it with the completed form, and mail everything to the address printed on the notice.

Mail renewal takes longer than online — typically 2 to 3 weeks from the time the state receives your envelope — so send it early if your tags are expiring soon. Do not mail cash. Keep a copy of the form and your payment receipt in case the state loses your envelope, though this is rare.

If you lose your renewal notice, you can request a duplicate by calling the Missouri Department of Revenue at 573-526-2407 or visiting a local office. You can also renew online without the notice if you have your VIN and plate number.

Renewing in person at a Missouri Department of Revenue office

Visit any Missouri Department of Revenue office with your current registration, proof of insurance, and a valid ID. Bring a check, debit card, or credit card for payment. The office will process your renewal on the spot, and you can drive home with your new tags the same day.

In-person renewal is necessary if your vehicle has a lien, if you need to change vehicle ownership information, if your title is from another state, or if you are renewing a commercial or special-use plate. It is also the only option if you missed the renewal important date and your tags have already expired.

Wait times at Missouri Department of Revenue offices vary by location and time of day. Offices are typically less busy on weekday mornings and more crowded on Saturdays and late afternoons. You can find your nearest office and its hours at dmv.mo.gov.

What you need to renew and when you can start

You can renew your tags up to six months before they expire. This means if your tags expire in December, you can renew starting in June. Renewing early gives you time to receive your new tags by mail or to schedule an office visit without rushing.

For online or mail renewal, you need your current registration and a valid payment method. For in-person renewal, bring your current registration, proof of insurance (your insurance card or a letter from your insurer), and a valid driver's license or ID. All renewal methods require proof that your vehicle is currently insured.

If your registration has expired, you cannot renew online or by mail — you must go to an office in person. The state considers expired registrations a separate issue from renewal and handles them differently.

Renewal fees and what affects the cost

Missouri registration fees are based on your vehicle's gross weight rating (the maximum weight it can safely carry). Heavier vehicles cost more to renew than lighter ones. The renewal notice tells you your specific fee, or you can see the fee schedule on dmv.mo.gov.

If you renew online, add the convenience fee charged by the payment processor — this is typically a few dollars but varies. Mail and in-person renewals do not include a convenience fee. Some vehicles, like those registered as commercial or for special use, have different fee structures.

If your vehicle's weight or use has changed since your last registration, your renewal fee may be different from what you paid last time. The renewal notice will show the correct amount for your current vehicle.

What happens if your tags expire before you renew

If your tags expire and you have not yet renewed, you cannot legally drive the vehicle on Missouri roads. You must renew in person at a Department of Revenue office — online and mail renewal are not available for expired registrations. Bring your current (expired) registration, proof of insurance, and a valid ID.

Driving with expired tags can result in a traffic citation and fine. If you are pulled over, tell the officer that you are actively renewing your registration. Having proof that you have applied (like a receipt from an office visit or a confirmation email from online renewal) may help, though it does not may provide you will not receive a citation.

If your renewal notice did not arrive in the mail, contact the Missouri Department of Revenue at 573-526-2407 to request a duplicate or to renew over the phone if that option is available.

Frequently Asked Questions

Can I renew my Missouri tags if I just bought the vehicle?

No. You must have a current Missouri registration in your name before you can renew. If you recently purchased the vehicle, you need to register it first. This requires a visit to a Department of Revenue office with your title, proof of insurance, and ID. Once your initial registration is complete, you can renew online or by mail in the future.

What if I moved and my address changed since my last registration?

You cannot renew online if your address has changed. Renew by mail using your renewal notice (the state will update your address when they process it), or visit an office in person with proof of your new address, such as a utility bill or lease. The office will update your address and process your renewal at the same time.

Do I need to show proof of insurance to renew online or by mail?

No. Online and mail renewal do not require you to show proof of insurance at the time you renew. However, Missouri law requires your vehicle to be insured. If you are stopped by police and cannot show proof of current insurance, you can receive a citation even if your tags are current.

How long do new tags take to arrive if I renew online?

The state typically mails new tags within 7 to 10 business days after you complete online payment. Delivery time depends on your location and the postal service. If your tags expire before they arrive, you can print a temporary registration from dmv.mo.gov to carry in your vehicle while you wait.

Can I renew someone else's vehicle tags?

You can renew by mail or online on behalf of someone else if you have their registration and can pay with your own card or check. For in-person renewal, the registered owner should visit the office if possible, but you can ask the office whether they allow a family member or authorized person to renew on the owner's behalf.
