South Carolina Sales Tax — 6%

South Carolina counties may adopt local option sales taxes by referendum — for capital projects, transportation, education and property tax relief — each adding 1%. Whether your county has adopted them, and how many, determines your rate.

The result is meaningful county-to-county variation on top of the 6% state rate, averaging 1.49%. Counties that have adopted property tax relief taxes are effectively substituting sales tax for property tax, which changes who pays.

South Carolina caps sales tax on motor vehicles at a fixed maximum rather than applying the percentage to the full price. On an expensive vehicle the effective rate becomes very small.

The cap is one reason South Carolina appears attractive for large vehicle purchases, though the state's separate property tax on vehicles — assessed annually — offsets much of the saving over time.

The South Carolina state rate of 6% applies to most retail sales of tangible goods. Counties, cities and special districts add their own rates on top, and because those are set locally the total varies within the state. The 7.49% figure quoted here is a population-weighted average — the rate at your own address may be meaningfully higher or lower.

Ranked 19 of 50 by average combined rate, South Carolina sits below the national population-weighted average of 7.53% by 0.04 percentage points. South Carolina also levies income tax, so sales tax is one part of the picture rather than the whole of it.

What gets taxed matters as much as the rate. States differ considerably on groceries, prescription drugs, clothing and services, and those exemptions can affect a household's real burden more than a percentage point on the headline rate. Check your state revenue department for the current exemption list before relying on any calculation for a business filing.
