What to do next
How it works
The calculator starts from your income after pre-tax contributions, subtracts South Carolina's standard deduction and personal exemptions where they exist, and applies a graduated state income tax with 2 brackets from 1.99% to 5.21%. Personal credits come off the tax. South Carolina allows a standard deduction of up to $15,000 for single filers that shrinks as income rises.
Things to keep in mind
South Carolina has no local income taxes. Itemized deductions and state-specific credits are not applied, so filers with large deductions will owe less than shown.
Some South Carolina rules, such as high-income phase-outs or special rates on certain income, are left out of this estimate. The state revenue department's own calculator or instructions have the full detail.
