South Carolina imposes a general state sales tax, along with local (county and municipal) and special district taxes. This calculator helps you estimate the total sales tax you'll pay on a purchase in South Carolina.
How South Carolina Sales Tax Works:
The calculation is straightforward but involves combining several rates:
State Sales Tax Rate: This is the base rate applied statewide. In South Carolina, the general state rate is typically 6%.
Local Sales Tax Rates: Counties and municipalities in South Carolina can levy their own sales taxes. These vary significantly by location. Common local rates can add 1% to 2% or more to the total.
Special District Taxes: Some areas may have additional taxes for specific purposes, such as public transportation or infrastructure projects. These rates are usually lower, often around 0.5%.
The Calculation Formula:
The total sales tax is calculated by summing up all applicable rates and then applying that combined rate to the purchase amount.
Total Applicable Rate (%) = State Sales Tax Rate (%) + Local Sales Tax Rate (%) + Other Special District Rates (%)
Exemptions: Certain items may be exempt from sales tax in South Carolina, such as groceries (though some prepared foods are taxed), prescription medicines, and certain manufacturing machinery.
Rate Verification: Sales tax rates can change and vary significantly by specific county and municipality. Always verify the current rates for your specific location with the South Carolina Department of Revenue or your local tax authority for the most accurate information.
Use Cases: This calculator is useful for consumers estimating their final purchase price, businesses calculating expected sales tax revenue, and for budgeting purposes.
