Where to register your car in DeKalb County
You register your car at the DeKalb County Tax Assessor's office, not at the DMV. Georgia's tax assessor handles vehicle registration for your county, so if you live in DeKalb, that's where your registration paperwork goes. The main office is located in Decatur, but DeKalb County also runs satellite locations in other parts of the county to reduce wait times.
You can find the current office locations and hours on the DeKalb County Tax Assessor's website. Before you go in person, check whether your specific transaction requires an appointment or if walk-ins are accepted, since this can change based on how busy the office is.

What documents you need to bring
Bring your vehicle title (the official ownership document), proof of insurance, and a valid photo ID. Your insurance company can provide proof of coverage on the spot if you don't have a printed copy—many now offer digital proof through their apps or email.
You'll also need to fill out the vehicle registration form. DeKalb County's Tax Assessor's office has these forms available on their website and at the office itself, so you can print one ahead of time or fill it out when you arrive. If you're registering a vehicle you just bought, bring your bill of sale or purchase agreement as proof of ownership transfer.
If someone else is signing documents on your behalf, bring a power of attorney document that shows they have legal authority to act for you. The office staff can tell you what form they accept.
How much registration costs
Georgia's registration fee is based on your vehicle's weight, not its value. Heavier vehicles cost more to register than lighter ones. A typical passenger car costs less than a truck or SUV. The state fee ranges depending on weight, but DeKalb County adds a local fee on top of the state amount.
The exact total varies, so call the DeKalb County Tax Assessor's office or check their website for the current fee schedule. If you're registering a vehicle for the first time in Georgia, you'll pay the full annual fee. If you're renewing mid-year, the fee is prorated based on how many months are left in the registration year.
Timeline for new vehicle registration
You have 30 days from the date you buy a car to register it in Georgia. If you buy from a dealership, they often handle the paperwork and send it to the tax assessor on your behalf, but you're still responsible for making sure it gets done. If you buy from a private seller, you handle the registration yourself.
Once you submit your paperwork to the DeKalb County Tax Assessor's office, your registration is usually processed within a few business days. You'll receive your license plate and registration card by mail. If you need the plate right away, ask the office whether they can issue a temporary tag while you wait for the permanent one.
Renewing your registration
You can renew your registration online through the Georgia Department of Revenue website, by mail, or in person at the DeKalb County Tax Assessor's office. Online renewal is the fastest option if your vehicle passed its emissions test (if required) and you have no outstanding violations or fines.
Renewal notices are mailed to your address on file about 30 days before your registration expires. If you don't receive one, you can still renew—the office has your information. You'll need proof of insurance again at renewal time, even if nothing has changed.
If your vehicle requires an emissions inspection, you must pass that test before you can renew. Georgia requires emissions testing for vehicles in certain counties, and DeKalb County is one of them. You can get tested at any state-approved emissions testing station, then bring your passing certificate to the tax assessor's office or submit it with an online renewal.
Registering a vehicle you bought out of state
If you moved to Georgia or bought a car in another state, you need to transfer the registration to DeKalb County. Bring your out-of-state title, your bill of sale or purchase agreement, proof of insurance, and a valid ID. The tax assessor's office will walk you through the title transfer process.
Some states' titles need to be notarized before Georgia will accept them. Call the DeKalb County Tax Assessor's office before you go in to ask whether your state's title requires notarization. If it does, you can get a notary at the office itself or at many banks and shipping stores.
What happens if you miss the registration important date
Driving with an expired registration in Georgia is a traffic violation. If you're pulled over, you can face a fine. The longer your registration is expired, the higher the penalty can be. If you realize your registration has expired, renew it as soon as you can.
If you're renewing late, you still pay the same registration fee—there's no late fee added in Georgia. However, you may owe a penalty if you were cited for driving with an expired tag. Contact the DeKalb County Tax Assessor's office or the court that issued the citation to find out what you owe.

What if I don't have my vehicle title?
Contact the DeKalb County Tax Assessor's office or the Georgia Department of Revenue to request a duplicate title. You'll need to provide proof of ownership and pay a fee. The process takes a few weeks, so start it as soon as you realize the title is missing.
Can I register my car by mail?
You can renew by mail if your registration is current and your vehicle has passed inspection. For new registrations or title transfers, mail-in options are limited. Call the tax assessor's office to ask what documents they accept by mail for your specific situation.
What's the difference between a temporary tag and a permanent license plate?
A temporary tag is a paper tag the tax assessor's office can issue on the spot while your permanent metal plate is being made. The temporary tag is valid for a set number of days. Once your permanent plate arrives by mail, you install it on your vehicle and the temporary tag is no longer valid.
