Do I pay capital gains tax when I sell my primary home in Marietta?

Capital gains tax on a primary home sale in Marietta is governed by federal tax law, not anything specific to Georgia or Cobb County, and it depends on how long you owned and lived in the home, your cost basis, and how much the property appreciated. Many primary-residence sales qualify for an exclusion under federal rules, but whether it applies and how much is covered depends on your specific situation. A CPA or tax attorney can confirm your actual exposure before you list, since this varies household by household.
