South Carolina Car Sales Tax Calculator
South Carolina's vehicle sales/use tax depends on where you register and other factors, so it isn't a single statewide figure. Use the calculator and the official South Carolina Department of Motor Vehicles (SCDMV) source below to confirm what applies to your purchase.
Estimate your South Carolina car sales tax
Enter the vehicle price. If South Carolina gives a trade-in tax credit, add your trade-in value to reduce the taxable amount.
State rate only. Many South Carolina counties and cities add a local sales tax on top, so your actual total may be higher. Trade-in credit rules vary — confirm eligibility with the official source below.

Frequently asked questions
How much is sales tax on a car in South Carolina?
South Carolina does not reduce to one statewide vehicle tax rate — it varies by locality and purchase type. Check the official South Carolina Department of Motor Vehicles (SCDMV) source for the rate that applies to you.
Do I pay sales tax when buying a used car from a private seller in South Carolina?
In most states, sales or use tax on a private-party vehicle purchase is collected when you title and register the car, not at the point of sale. The rate is generally the same as a dealer sale. Confirm the private-sale rules with South Carolina Department of Motor Vehicles (SCDMV).
Does South Carolina give a sales tax credit for a trade-in?
Most states tax only the difference between the vehicle price and your trade-in value, which lowers the tax you owe. A handful of states tax the full price with no trade-in credit. Verify South Carolina's treatment before you rely on the estimate above.
Are there local or county car sales taxes in South Carolina?
Often, yes. The rate shown here is the South Carolina state rate only; many counties, cities, and transit districts add a local sales tax on vehicle purchases, so your combined rate can be higher. South Carolina Department of Motor Vehicles (SCDMV) publishes the official combined rates.
