The South Carolina capital gains tax calculator is a specialized state tax estimation tool designed for Palmetto State residents selling stocks, real estate, cryptocurrency, or business assets. In South Carolina, capital gains are included in individual state income tax returns, but the state provides a major tax incentive: under SC Code Sec 12-6-1150, South Carolina allows a 44% deduction for net long-term capital gains on assets held for more than one year. As a result, only 56% of your net long-term gain is subject to South Carolina individual income tax rates (which top out at 6.2%). Short-term gains (held one year or less) receive no state deduction and are fully taxed as ordinary income.
