Hawaii taxes long-term capital gains at up to 7.2%. Combined with the 20% federal rate and 3.8% NIIT, a high-income HI investor faces 31.1% on a large capital event. On a $1M gain, that is $310,500 in total tax, leaving $689,500 after tax.
Hawaii taxes capital gains at a preferential 7.25% rate (vs the standard 11% top income rate). Still one of the higher state rates nationally.
The difference between realizing a gain in Hawaii versus a zero-tax state like Texas or Florida is $72,500 per $1M in gains. For a $5M exit, the gap is $362,500. 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.
