South Carolina Tax Burden

South Carolina is a relatively low-tax state, ranking #27 out of 50 at 8.89%. The state income tax rate of 4.998% is among the higher rates nationally, significantly impacting residents' take-home pay.

Property taxes are a major factor here — at 0.56% effective rate, homeowners in South Carolina pay significantly more than the national median of ~1.1%. On a $300,000 home, that's approximately $168,000/year in property taxes alone. With a median household income of $54,760, the average South Carolina resident pays approximately $4,868 per year across all state and local taxes.

High income tax state: At 4.998%, South Carolina's income tax takes a significant bite. Consider maximizing pre-tax retirement contributions (401k, IRA, HSA) to reduce your state tax bill. If you're nearing retirement, evaluate whether relocating to a no-income-tax state could save you significantly on withdrawals.

Property tax protest: With an effective rate of 0.56%, property tax appeals are worth pursuing in South Carolina. Homeowners who formally protest their assessed value often achieve reductions of 5–15%. On a $300,000 home, that's a potential savings of $16,800/year. Check your county assessor's deadline — most states allow annual appeals.

High sales tax (7.43%): For major purchases — vehicles, appliances, furniture — calculate whether buying across state lines (if near a border) saves meaningful money. A $30,000 car purchase costs an extra $222,900 in sales tax in South Carolina.

For retirees: At 4.998% income tax, all retirement withdrawals are potentially taxable. Check whether South Carolina offers any exemptions for Social Security or pension income — many states do.
