These are the rules for a new car bought from a dealer. Used-car and private-sale rules can differ. How we check this data.
South Carolina charges 5% at the state level. Infrastructure maintenance fee instead of sales tax, capped at $500. That rate is higher than 16 states and lower than 29 states. County and city taxes may add to it, so check your local rate and enter the total in the calculator.
What to know in South Carolina
South Carolina charges an infrastructure maintenance fee instead of sales tax on vehicles: 5% of the price after your trade-in, capped at $500. The cap is reached once the taxable amount hits $10,000, so for almost any new car the fee is a flat $500.
That changes the math on trade-ins. Unless your trade-in brings the taxable price under $10,000, it saves nothing in tax, so compare the dealer's offer with a private sale on value alone. Budget separately for the property tax South Carolina counties charge on vehicles each year.

Rebates and fees
The calculator charges tax on the price before any manufacturer rebate. Ask the dealer how South Carolina treats your specific rebate. Title, registration and dealer documentation fees vary, so ask for an itemized out-the-door price and put the fee total in the calculator.
