How North Dakota taxes this gain

How We Calculate & Keep This Accurate

Short-term gains are taxed as the top slice of ordinary income: tax(income + gain) − tax(income) at federal ordinary rates. Long-term gains use the 0%/15%/20% preferential brackets stacked on ordinary taxable income, plus 3.8% NIIT when MAGI crosses the threshold. North Dakota tax on the gain is the same stacking method at state rates: state tax on (income + gain) minus state tax on income.
