Why the rate here is not the whole story
Georgia's state sales and use tax is 4 percent, and 3 percent of DeKalb County tax applies at every address in the county through the MARTA transit tax, an education SPLOST and the equalized homestead option sales tax. Outside the City of Atlanta the county adds a 1 percent SPLOST for a combined 8 percent, while the DeKalb part of Atlanta instead carries the city's municipal option sales tax, an extra local MARTA levy and a city TSPLOST for 8.9 percent. The county line is not the tax boundary here, so an address inside Atlanta pays a different rate from one outside it.
