Renewing your Cobb County vehicle tag

Cobb County vehicle tag renewal happens through the Cobb County Tax Assessor's Office, not through the state. You can renew by mail, online, or in person at one of their locations. The renewal notice arrives about 30 days before your tag expires, and you have a grace period of up to 30 days after expiration to renew without penalty—but driving on an expired tag is illegal, so renew before the expiration date on your current tag.

Your renewal notice will show the amount due, which includes the ad valorem tax (based on your vehicle's assessed value) plus a $20 tag fee. The total varies by vehicle value and model year. You'll need your current tag number and vehicle identification number (VIN), both of which appear on your renewal notice.

  • Your renewal notice arrives about 30 days before expiration and shows the exact amount due, which includes ad valorem tax plus a $20 tag fee.
  • Online renewal through the Cobb County website is the fastest method and requires your renewal notice number and last four digits of your Social Security number or federal employer ID.
  • If you renew by mail, send your payment and signed renewal notice to the address on the notice; processing takes 7 to 10 business days.
  • Vehicles with a lien or loan require the lienholder's release or written permission before you can renew the tag in your name.

Renewing online through Cobb County's website

Online renewal is the fastest option and requires no trip to an office. Go to the Cobb County Tax Assessor's website and select the vehicle tag renewal option. You'll need your renewal notice number (printed on the notice the county mailed you) and the last four digits of your Social Security number or federal employer ID number. Enter your vehicle information and payment method—Cobb County accepts credit cards, debit cards, and electronic check payments.

After you submit payment, you'll receive a confirmation number when ready. Your new tag will be mailed to the address on file within 7 to 10 business days. If you need the tag sooner, you can pick up a temporary tag at the Tax Assessor's office while you wait for the permanent one.

Renewing by mail

To renew by mail, write a check or money order for the amount shown on your renewal notice. Do not send cash. Sign the renewal notice where indicated and mail both the notice and payment to the address printed on the notice itself. Include a note with your phone number so the county can contact you if there's a problem with your payment.

Mail processing takes 7 to 10 business days after the county receives your envelope. Your new tag will arrive separately by mail. If your renewal notice has been lost, call the Cobb County Tax Assessor's Office at 770-528-8800 to request a duplicate before mailing payment.

Renewing in person at the Tax Assessor's Office

The main Cobb County Tax Assessor's Office is located at 100 Cherokee Street, Marietta, GA 30090. Satellite offices operate in Acworth, Kennesaw, and Powder Springs. Bring your renewal notice, a valid photo ID, and payment in the form of cash, check, debit card, or credit card. If you're renewing for someone else, bring a power of attorney or written authorization from the vehicle owner.

In-person renewal is processed when ready, and you can leave with a temporary tag the same day. Your permanent tag will be mailed to you within 7 to 10 business days. Office hours vary by location, so check the Tax Assessor's website or call 770-528-8800 before you visit.

What happens if your vehicle has a lien or loan

If you still owe money on your vehicle, the lender (bank, credit union, or finance company) holds a lien on the title. You cannot renew the tag in your name until the lien is released or the lienholder gives written permission. Contact your lender and ask for a lien release or a letter authorizing tag renewal. Some lenders release the lien automatically once the loan is paid off; others require a written request.

Bring the lien release or authorization letter to the Tax Assessor's Office when you renew, or include it with your mail-in payment. If you're renewing online, you may need to call the office at 770-528-8800 to upload or fax the document before your payment is processed.

Late renewal and penalties

If your tag expires and you do not renew within 30 days, you'll owe a late penalty in addition to the regular renewal fee. Driving on an expired tag is a traffic violation and can result in a citation. The grace period exists to account for mail delays, but it does not extend your legal right to drive—renew before the expiration date printed on your current tag.

If you've already missed the important date, renew as soon as possible. The Tax Assessor's Office will calculate the penalty based on how long the tag has been expired. You can renew online, by mail, or in person using the same methods described above.

Frequently Asked Questions

Can I renew my Cobb County tag if I've moved out of state?

No. Cobb County tags are for vehicles registered to a Cobb County address. If you've moved, you must register your vehicle in your new state and obtain a tag from that state's motor vehicle department. You cannot renew a Cobb tag for an out-of-state address.

What if I lost my renewal notice?

Call the Cobb County Tax Assessor's Office at 770-528-8800 and provide your vehicle's VIN and tag number. They'll mail you a duplicate notice or give you the renewal amount over the phone so you can pay online or in person without the original notice.

How long does it take to receive my new tag after I renew?

Processing takes 7 to 10 business days after the county receives your payment or processes your online submission. If you renew in person, you can pick up a temporary tag when ready and use it while you wait for the permanent tag to arrive by mail.

Do I need an inspection before I renew my tag?

Georgia does not require vehicle inspections for tag renewal. However, your vehicle must be registered and insured. Cobb County may verify that your vehicle has active insurance before processing your renewal.

What if the amount on my renewal notice seems wrong?

The renewal amount is based on your vehicle's assessed value, which the Tax Assessor's Office determines. If you believe the value is incorrect, you can file a value protest with the Tax Assessor's Office. Call 770-528-8800 to learn about the protest process and important date.
