South Carolina Personal Income Tax Laws

Most, but not all states collect personal income tax, which considers an individual's salary or any other forms of income. Some states require higher earners (those in the higher "tax brackets") to pay a higher percentage of their income, while others have a so-called "flat tax" that applies to all taxpayers. Those that don't collect income tax often make up for it in other ways, including sales and business taxes. The revenue raised from personal income tax is used to fund education and other state initiatives. South Carolina employs a progressive tax rate.

Overview of Personal Income Tax in South Carolina

South Carolina's progressive tax rate means lower earners are taxed at a much lower rate than high earners. For instance, taxable income between $2,910 and $5,820 is taxed at 3 percent, while income above $14,550 is taxed at 7 percent. Individual personal income tax rates never exceed 7 percent in South Carolina. The limits are doubled for married couples filing joint returns. The tax rate for corporations in South Carolina is 5 percent.
