About South Carolina income tax
South Carolina uses progressive tax brackets ranging from 3% up to 6.4%. Because the system is progressive, your first dollars are taxed at the lowest rate and only income above each threshold is taxed at the higher rates — so your effective rate is lower than the 6.4% top rate.
The lowest bracket is 0%, so a portion of income is untaxed.
This page applies South Carolina's published single-filer brackets to the income you enter. It doesn't include South Carolina's own standard deduction, personal exemptions, or credits, which can lower your actual bill.
