South Carolina has a graduated state income tax, meaning people pay different amounts — ranging from zero to 6 percent — depending on their income level. The state has several benefits for older residents, including no estate tax or inheritance tax, and no state tax on Social Security.
South Carolina has an individual income tax, with a top rate of 6 percent. Residents who have taxable income of $3,560 or less pay no income tax, while those with income between $3,560 and $17,830 pay 3 percent income tax, minus $107. Anyone who is paid more than $17,830 per year pays 6 percent income tax, minus $642. Somebody with $100,000 in income would pay $6,000 — the 6 percent — minus $642, for a total of $5,358.
Retirement income is generally taxed as regular income in South Carolina, but there are deductions for which some people qualify. For example, if you are totally and permanently disabled, or if you’re a volunteer firefighter or emergency worker, you can claim certain deductions to reduce your tax bill.
Net capital gains are considered taxable income in South Carolina, but the state allows residents to deduct 44 percent of their net long-term capital gains. After that deduction, whatever remains is taxed at the rate appropriate for their income bracket, which is 6 percent on income of $17,830 or more.
The state does not tax Social Security, but you may pay federal taxes on a portion of those benefits, depending on your provisional income. In most cases, provisional income is equal to the combined total of half your Social Security benefits, your adjusted gross income (not including any Social Security benefits) and any tax-exempt interest.
