How to Register Your Car Through Missouri's Department of Revenue

Where to register your car in Missouri

Missouri's Department of Revenue handles vehicle registration through its office in Jefferson City, but you do not have to go there in person. You can register your car at any of Missouri's 114 county assessor offices, which process registrations on behalf of the state. If you prefer to handle it by mail or online, the Department of Revenue accepts both, though the online option is limited to renewals and certain transactions.

The Jefferson City office is the central hub — it processes applications, issues titles, and handles disputes — but it exists mainly as a processing center. Most people never need to contact it directly. Your county assessor's office is your actual point of contact for registration work.

Registration fees vary by vehicle weight and type, and you must pay sales tax on the vehicle value unless you have a tax exemption.
Processing takes 10 to 15 business days by mail; county offices often complete it the same day or within a few days.
Your county assessor's office can tell you the exact fee for your vehicle and accept payment when ready, making it faster than mailing to Jefferson City.

Documents you need for a new registration

Bring or submit the vehicle title (or bill of sale if you do not have the title yet), your driver's license or state ID, and proof that you live in Missouri. Proof of residency can be a utility bill, lease, mortgage statement, or bank statement dated within the last 60 days. You will also need to complete Form 108, the process for Missouri Title and Registration, which the county assessor's office provides or you can read from the Department of Revenue website.

If you are registering a vehicle you just bought, bring the bill of sale or purchase agreement showing the price. The Department of Revenue uses this to calculate sales tax. If the previous owner's name is still on the title, bring that title too — the assessor will process the transfer.

For a vehicle with an existing Missouri title, you need only the title itself, your ID, proof of residency, and the completed Form 108. If you are renewing an existing registration, you can do this online through MyDMV if you have your current registration number and vehicle identification number (VIN).

Registration fees and what they cover

Missouri registration fees are based on your vehicle's weight and type. A passenger car typically costs between $150 and $200 for the first registration, though the exact amount depends on the vehicle's gross vehicle weight rating (GVWR). Trucks, motorcycles, and commercial vehicles have different fee schedules. Your county assessor's office can quote the exact fee before you pay.

You must also pay Missouri sales tax on the vehicle's purchase price, unless you have a tax exemption (such as a military exemption or a vehicle purchased from a family member). The tax rate is 4.225 percent statewide, plus any local sales tax your county adds. If you bought the car out of state and already paid sales tax there, Missouri may credit that amount, but you will still owe the difference if Missouri's rate is higher.

The registration fee covers your license plate, registration card, and one year of registration. When you renew, you pay only the registration fee again; there is no additional sales tax unless you are registering a newly purchased vehicle.

Registering in person at your county assessor's office

This is the fastest route for most people. Find your county assessor's office online by searching "[your county] assessor Missouri" — each county maintains its own office with its own hours. Bring all documents listed above, completed Form 108, and payment for the registration fee and sales tax. Most offices accept cash, check, and card.

Processing usually takes a few minutes to a few hours. You will receive your registration card and license plate (or a temporary plate if the permanent one needs to be mailed) the same day. If you are transferring a title from another state, processing may take a few days because the office must contact that state's motor vehicle department.

Call ahead if you have questions about what to bring or whether your specific situation requires extra documents. County offices are familiar with unusual cases — vehicles with liens, vehicles titled to businesses, vehicles with damage history — and can tell you exactly what they need.

Registering by mail to Jefferson City

Mail your completed Form 108, title or bill of sale, proof of identity, proof of residency, and a check or money order to the Missouri Department of Revenue, Vehicle Registration Section, Jefferson City, MO 65105. Include a note with your phone number so they can contact you if something is missing.

Processing takes 10 to 15 business days from the date the Department receives your packet. You will not know the exact arrival date, so add a few extra days to account for mail transit. Once processed, the Department mails your registration card and license plate to your address on file.

Mailing is useful if you cannot visit a county office during business hours or if you live far from one. However, if something is missing from your packet, the Department will mail it back to you, adding another 10 to 15 days to the process. The county assessor route avoids this delay because staff can tell you when ready if a document is incomplete.

Renewing your registration online

If your registration is current and you are straightforward renewing it, you can use Missouri's MyDMV portal at dmv.mo.gov. Log in with your driver's license number and date of birth, enter your vehicle's VIN and current registration number, and pay the renewal fee online. The system accepts credit and debit cards.

You cannot renew online if your vehicle has a lien, if you are changing the registered owner, if you are registering a newly purchased vehicle, or if your registration has been expired for more than one year. In those cases, use the county assessor's office or mail to Jefferson City.

Online renewal takes a few minutes, and your new registration card is mailed to you within 7 to 10 business days. You can continue driving on your current registration until the new one arrives.

What happens if your registration is expired

You cannot legally drive a vehicle with an expired registration. If your registration has been expired for fewer than 30 days, you can renew it at your county assessor's office or by mail without penalty. If it has been expired for more than 30 days, you may owe a late fee in addition to the renewal fee. The county assessor can tell you the exact amount.

If you are renewing a registration that expired more than one year ago, you cannot use the online portal. You must go to the county assessor's office or mail your documents to Jefferson City. Bring the expired registration card along with your other documents so the assessor knows you are renewing an old registration rather than registering a new vehicle.

Frequently Asked Questions

Can I register my car without a title?

If you have a bill of sale from the seller but no title yet, you can register the vehicle with the bill of sale. The Department of Revenue will issue you a title once the registration is processed. If you have neither a title nor a bill of sale, you will need to contact the previous owner or the Department of Revenue directly to sort out the ownership chain.

How long does registration take if I go to the county assessor's office?

Most county offices complete registration the same day or within a few days. Processing time depends on how busy the office is and whether your documents are complete. Call your county assessor's office to ask their typical turnaround time.

What if I move to a different county in Missouri?

You do not need to re-register your vehicle when you move within Missouri. Your registration remains valid at your new address. However, if you move out of state, you must register your vehicle in the new state within the timeframe that state requires — usually 30 to 60 days.

Do I have to pay sales tax if I bought the car from a family member?

Missouri exempts vehicles purchased from a spouse, parent, child, or sibling from sales tax. Bring proof of the family relationship (marriage certificate, birth certificate, or ID showing the same last name) along with your bill of sale. The county assessor will waive the tax if you meet the relationship requirement.

Can I register a vehicle that has a lien on it?

Yes. Bring the title showing the lienholder's name, and the county assessor will register the vehicle with the lien noted. The lienholder's name will appear on your registration card. You can drive the vehicle normally; the lien straightforward means the lender has a legal claim to it until the loan is paid off.
