Why the rate here is not the whole story
South Carolina's state sales tax is 6 percent and Marlboro County adds 2 percent in county-wide local sales taxes approved by referendum of the county's voters, made up of a 1 percent Local Option Sales and Use Tax and a 1 percent School District Tax, for a combined 8 percent. South Carolina cities and towns cannot levy a general sales tax of their own, so the county is the only jurisdiction below the state that levies here and the 8 percent rate applies at every address in the county. Unprepared food that can be bought with USDA food coupons is exempt from the state 6 percent, but the county's Local Option tax still applies to it, so qualifying groceries are taxed at 1 percent.
