Why the rate here is not the whole story
Georgia's state sales and use tax is 4 percent and Clayton County levies 4 percent at every address in the county through the MARTA transit tax, a local option sales tax, an education SPLOST and a special purpose SPLOST, for a combined 8 percent in most of the county. The part of the City of College Park that lies in Clayton County carries a further 1 percent that the chart lists only as other, taking those addresses to 9 percent. The county line is not the tax boundary here, so a College Park address has to be checked separately.
