How South Carolina Sales Tax Works: SCDOR Rules
South Carolina imposes a 6.00% statewide sales tax on the gross proceeds of retail sales of tangible personal property under South Carolina Code Title 12, Chapter 36. However, total sales tax at checkout depends heavily on county-level referendums.
Types of Local Option Taxes in South Carolina:
- Local Option Sales Tax (LOST): A 1.00% tax levied by participating counties to reduce municipal and county property taxes.
- Capital Projects Sales Tax (CPST): A 1.00% voter-approved tax dedicated to specific road, courthouse, water, and park infrastructure projects.
- Transportation Sales Tax: A dedicated 1.00% surtax for mass transit and highway construction (e.g., Charleston and Richland counties).
- School District / Education Capital Improvement Tax: An additional 1.00% tax in select counties dedicated to school construction and technology.
Because these county additions vary from 0% in upstate manufacturing centers like Greenville to 3.00% in coastal tourism centers like Charleston, using the exact county rate is vital for accurate reverse calculations.
South Carolina Sales Tax Rates by County (2026)
South Carolina sales tax rates reflect the state 6.00% baseline plus applicable local option taxes. The table below outlines major counties:
South Carolina's $500 Maximum Tax on Motor Vehicles
One of the most distinctive aspects of South Carolina tax law is the $500 maximum tax cap under S.C. Code § 12-36-2110 and the Infrastructure Maintenance Fee (IMF) on qualifying motor vehicles, motorcycles, boats, and recreational vehicles.
Worked Example: Backing Out 9.00% Charleston Sales Tax
Suppose you purchase furniture or electronics in Charleston, South Carolina, and the final receipt total is $545.00 (inclusive of the 9.00% combined rate).
Avoid the Subtraction Error: Multiplying $545.00 by 9% gives $49.05, which leads to an erroneous pre-tax estimate of $495.95 ($4.05 lower than actual). Dividing by the multiplier 1.09 accurately accounts for the fact that the 9% was originally calculated on the $500 base.
Filing Form ST-3 with the South Carolina Department of Revenue
South Carolina merchants registered on MyDORWAY must file Form ST-3. When reporting sales that include tax:
Enter calculated pre-tax retail sales. Reverse calculate from gross drawer totals so you do not pay sales tax on collected sales tax.
Deduct exempt sales (unprepared food, resale certificates, out-of-state shipments) claimed on Schedule A.
Break down taxable proceeds by county code to ensure local option taxes (LOST/CPST) are remitted to the correct jurisdiction.
