The Tax Commissioner’s Office is established by the Georgia Constitution, and is responsible for every phase of collecting and disbursing ad valorem property taxes. Our staff is separated into two divisions:

Our Property Tax Division bills, collects, and distributes ad valorem property taxes for real, personal property, heavy duty equipment, mobile homes, and public utilities. In addition, this division processes homestead exemptions and conducts tax sales. They are also responsible for preparing the tax digest each year.

Our Motor Vehicle Division serves as a tag agent on behalf of the Georgia Department of Revenue. They collect and distribute ad valorem property taxes for vehicles as well as enforce local laws for registration requirements, insurance, emissions, and mobile home ownership.

We work closely with:

  • Cobb County Tax Assessor’s Office
  • Cobb County Board of Commissioners
  • Board of Equalization
  • Board of Education
  • County Finance
  • Georgia Department of Revenue
  • Community Improvement Districts
  • City authorities

In particular, the Board of Tax Assessors (BTA) determines property values as well as maintains property ownership records for tax purposes. The BTA is appointed by the Board of Commissioners and is not under the authority of the Tax Commissioner.
