What Is the Sales Tax Rate in South Carolina?
South Carolina charges a 6% state sales tax on most purchases. On top of that, many counties add their own local option sales tax, which pushes the combined average closer to 7.5% in a lot of areas. The exact rate you pay depends on the county where the sale happens, so a purchase in one part of the state can cost noticeably more in tax than the same item bought an hour away.
USACalculator built this South Carolina version because the rate that actually applies at checkout depends on local option taxes, not just the state's base 6%. Pick your county below and the calculator applies the right combined rate automatically.
Using the Calculator
South Carolina is preselected in the dropdown with a representative combined rate. Enter the price of what you're buying, or swap in your own county's exact combined rate if you know it, and the total updates immediately. Planning a bigger purchase, like a vehicle? South Carolina taxes those differently through our South Carolina Car Loan Calculator, which factors in the state's separate vehicle fee instead.
How the Calculation Works
The formula is simple: multiply your purchase price by the combined tax rate to get the tax owed, then add that to the original price for your total. South Carolina applies sales tax based on the location of the sale, so two stores in different counties can post different tax totals on an otherwise identical receipt, purely because their local option rates differ.
South Carolina-Specific Sales Tax Information
State Sales Tax
The base rate is 6% statewide, set by the South Carolina Department of Revenue and applied to most tangible goods and many services.
Local Option Sales Tax
Counties can adopt their own local option sales tax, usually through a voter referendum, layered on top of the state's 6%. This is why South Carolina doesn't have one single combined rate the way some states with a hard local cap do.
Combined Rate
Across the state, combined rates commonly land near 7.5% on average once local option taxes are included, though your exact number depends on the specific county. Check dor.sc.gov for the current rate list by jurisdiction.
Tax Exemptions
Most unprepared grocery food is exempt from the state's 6% sales tax, though local option taxes in some counties may still apply to groceries, so the exemption isn't always total. Prescription medications are generally exempt as well. South Carolina also runs an annual sales tax holiday, typically the first weekend of August, covering clothing, school supplies, and computers, with exact dates and item lists published each year by the Department of Revenue.
Example Calculation
Say you're buying a $250 item in a county with a combined rate of 7.5%. The math looks like this:
| Item | Amount |
| Purchase Price | $250.00 |
| Sales Tax (7.5%) | $18.75 |
| Total Price | $268.75 |
Buy the same item in a county with no local option tax, and the total drops closer to the 6% state-only rate, even though nothing about the item itself changed.
Why South Carolinians Use This Calculator

People budgeting a big-ticket purchase, like furniture or electronics, run the numbers here first, then move on to our South Carolina Mortgage Calculator or South Carolina Paycheck Calculator to see how it fits into the rest of their monthly budget.
Common Mistakes to Avoid
- Assuming every county charges the same combined rate. Local option taxes vary widely across South Carolina.
- Forgetting that vehicle purchases use a separate Infrastructure Maintenance Fee, not the general sales tax rate.
- Treating grocery exemptions as total, when some counties still apply local option tax to food purchases.
- Missing the August sales tax holiday window when shopping for school clothes and supplies.
