New Jersey taxes long-term capital gains at up to 10.8%. Combined with the 20% federal rate and 3.8% NIIT, a high-income NJ investor faces 34.6% on a large capital event. On a $1M gain, that is $345,500 in total tax, leaving $654,500 after tax.
New Jersey taxes capital gains as ordinary income at rates up to 10.75%. NJ is one of the few states with no preferential long-term capital gains rate.
The difference between realizing a gain in New Jersey versus a zero-tax state like Texas or Florida is $107,500 per $1M in gains. For a $5M exit, the gap is $537,500. 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.
