what is south carolina state tax rate
South Carolina has six marginal tax brackets, ranging from 0.00% (the lowest South Carolina tax bracket) to 7.00% (the highest South Carolina tax bracket). Each marginal rate only applies to earnings within the applicable marginal tax bracket, which are the same in South Carolina for single filers and couples filing jointly. The Federal Income Tax, by contrast, has different tax brackets for married, single, and Head of Household taxpayers.
