North Dakota capital gains tax estimator

Estimate North Dakota tax impact from a single sale.

How this calculator works

Step 1 calculates your capital gain using cost basis and sale proceeds. If you provide dates, the tool classifies the holding period for reference.

Step 2 applies the 40% long-term exclusion (if eligible) and adds the remaining gain to your other North Dakota taxable income before applying the bracket schedule.

Step 3 shows the North Dakota tax impact. The marginal rate reflects the bracket your total income lands in after the gain.

Frequently asked questions

Does North Dakota have a special long-term gain rate?

North Dakota taxes capital gains as ordinary income, but long-term gains receive a 40% exclusion before applying the brackets. Some qualified gains or extraordinary dividends may qualify for additional deductions, which are not applied here.

What if I have a loss?

Losses are displayed for context. Check North Dakota's rules for how losses offset gains.

Do I need to adjust for residency?

Part-year and nonresident filers should prorate North Dakota-source income using the allocation percent on their return.
