Individual Income Tax
South Carolina utilizes a graduated state individual income tax system, with rates that are currently being phased down.
- State Rates (2025): Rates range from 0.00% up to a top marginal rate of 6.0% (effective July 1, 2025, reduced from 6.2% in 2024). The zero percent bracket applies to the lowest segment of taxable income.

- Additionally, residents aged 65 and older are eligible for a $15,000 deduction on any source of income, which includes retirement income.
- Local Income Tax: South Carolina does not impose a local or county income tax.
Sales and Use Tax
Sales tax combines a standard state rate with substantial local additions, resulting in a variable combined rate.
- State Rate: The general state sales tax rate is a uniform 6.00% on the retail sale of most tangible personal property and certain services.
- Local Taxes: Most counties impose an additional local option sales tax, which can range from 1.0% to 3.0%.
- Combined Rate: The total combined state and local sales tax rate can reach up to 9.0% in the highest-taxed municipalities (e.g., Charleston, Richland/Columbia area) but averages around 7.49% statewide.
- Tax on Groceries: Unprepared food (groceries) is exempt from the 6.00% state sales tax but is subject to a reduced 1.0% local tax rate in most counties.
- Use Tax: A state use tax of 6.00% plus the applicable local rate applies to taxable items purchased outside of South Carolina but used, stored, or consumed in the state if state sales tax was not collected.
Property Tax (Ad Valorem Tax)
Property taxes in South Carolina are collected exclusively at the local level and are notable for being among the lowest in the U.S. for primary residences.
- Assessment Ratios: Property is assessed at a fraction of its market value, with rates depending on the property type:
- Owner-Occupied Primary Residence (4% Rule): 4.0% of fair market value.
- Second Homes/Commercial Property: 6.0% of fair market value.
- Personal Motor Vehicles: 6.0% of market value.
- Homestead Exemption: Seniors aged 65 or older, blind, or permanently disabled homeowners who have been residents for at least one year are eligible for the Homestead Exemption, which exempts the first $50,000 of their primary residence’s fair market value from all local property taxes.
- Appraisal Cap: Increases in a property’s market value due to reappraisal are capped at 15% every five years, unless the property is sold or improved.
Corporate Income and License Tax
South Carolina imposes a low, flat-rate corporate income tax.
- Corporate Income Tax Rate: The corporate income tax rate is a flat 5.0% of the corporation’s South Carolina taxable net income. This is one of the lowest corporate rates in the Southeast.
