What is South Carolina Individual Income Tax?
South Carolina has a simplified income tax structure which follows the federal income tax laws. South Carolina accepts the adjustments, exemptions and deductions allowed on your federal tax return with few modifications. Your federal taxable income is the starting point in determining your state income tax liability. Individual income tax rates range from 0% to a top rate of 7% on taxable income. Tax brackets are adjusted annually for inflation.
