South Carolina levies a 6.00% state sales tax on most retail purchases. Local jurisdictions add an average of 1.60%, bringing the typical combined rate to 7.60%. Rates vary significantly by county and municipality.
On large purchases like a $55,000 vehicle, SC sales tax comes to $4,180.00 at the combined rate. On a $150,000 boat or RV, the tax bill is $11,400.00. These are significant costs that HNW buyers often plan around domicile or purchase location.
South Carolina residents who itemize deductions can deduct either state income taxes OR state and local sales taxes (SALT), not both. For most SC residents, the income tax deduction is larger. But in years with major purchases, the sales tax deduction may exceed it.
