Does South Carolina tax Social Security?
Does not tax Social Security
No. Social Security taxed on your federal return is not taxed by South Carolina.
What the South Carolina Department of Revenue says
We do not paraphrase the rule from memory. This is the state's own wording, copied from the page linked below it:
“Social Security benefits and railroad retirement taxed for federal purposes are not subject to tax in South Carolina.”
Federal tax is a separate question
Even though South Carolina does not tax it, the IRS can still tax part of your Social Security on your federal return. Whether it does depends on your other income. Our taxable Social Security calculator follows the IRS worksheet line by line, and this guide explains the rule.
You can ask Social Security to withhold federal tax from each payment. Withholding for South Carolina state tax, if you need it, is arranged with the state, not with Social Security. State rules change with new laws, so check with the South Carolina Department of Revenue before you file.
