Full transcript
Overview
If you do business in South Carolina, sales tax can get confusing fast. Here's a quick breakdown of the basics.
Who administers it
South Carolina sales tax is administered by the South Carolina Department of Revenue.
State and local rates
The WGA page lists South Carolina's statewide base sales tax rate as 6%. Local rates can stack on top and are generally based on the delivery address.
Economic nexus
Nexus means a business may have enough connection to a state that its sales tax responsibilities should be reviewed. For remote sellers, the WGA page lists South Carolina's economic nexus threshold as $100,000 in sales.
Filing frequency
The WGA page notes that filing may be monthly, quarterly, or annually, depending on liability. The practical goal is to know the assigned schedule and keep collected tax matched to it.
What to watch for
One South Carolina watch-out: local option taxes vary by county, and residents over eighty-five qualify for a rate reduction that point-of-sale systems often miss.
