South Carolina taxes long-term capital gains at up to 6.5%. Combined with the 20% federal rate and 3.8% NIIT, a high-income SC investor faces 30.3% on a large capital event. On a $1M gain, that is $303,000 in total tax, leaving $697,000 after tax.
The difference between realizing a gain in South Carolina versus a zero-tax state like Texas or Florida is $65,000 per $1M in gains. For a $5M exit, the gap is $325,000. Domicile planning is a key lever for HNW investors ahead of a major liquidity event.
The NIIT adds 3.8% on top of the federal rate for investors with Modified Adjusted Gross Income above $200,000 (single) or $250,000 (married filing jointly). This threshold is not indexed to inflation, so it captures most HNW capital gain transactions regardless of state.
