• A Georgia insurance policy
• A Georgia emission inspection
• Proof of name change (if different from your title)
• All owners of the vehicle present or a Power of Attorney for those who are not
• Funds for Title Ad Valorem Tax (TAVT) payment

TITLE AD VALOREM TAX†

TAVT is a one-time, per owner tax that is collected at the time the vehicle is titled. This tax applies to all title ownership changes, purchases or vehicles being brought into the state of Georgia by residents or new residents. For detailed information on TAVT, visit the Cobb County Tax Commissioner’s website Vehicle Taxes page.

†TAVT rates are set by the Georgia Department of Revenue (DOR). As-of 2018, it was determined that the TAVT rate will remain 7% indefinitely. TAVT rates are capped, by law, at 9.0%. See the Georgia DOR TAVT FAQ page for more information.

The Cobb County Water System and city water distributors partner with a wholesale water provider, the Cobb County-Marietta Water Authority, to distribute water to residents throughout the county.  Additionally, the Water System treats all sewer in the county. All customers are billed on a monthly basis for water and sewer fees based on use and the applicable rate per gallon. Residents residing in one of the six municipalities may be required to go through the city for activity and billing for water and sewer.

Cobb County, like much of Georgia, benefits from a utility industry that is deregulated – rates are consistently below national rates.  Georgia Power, Greystone Power, Marietta Power and Cobb EMC are electrical utility providers that operate in Cobb County.
