Why the rate here is not the whole story
Georgia's state sales and use tax is 4 percent and Rockdale County adds 3 percent of local tax, so the combined rate is 7 percent at every address in the county. The local part is an education SPLOST, a homestead option sales tax and a special purpose SPLOST, each imposed on a special district that is the county itself after a countywide referendum, so the county line is the tax boundary here and no city in the county levies a general sales tax of its own.
