North Dakota Tax Calculator

The North Dakota (ND) Tax Calculator is updated for the 2026/27 tax year and estimates North Dakota state income tax, federal income tax, and FICA/Medicare. North Dakota uses a progressive state income tax system based on the federal taxable income, applying lower marginal rates than many neighboring states. This calculator helps residents and part-year residents estimate their total tax and take-home pay for 2026/27.

North Dakota also offers various credits such as the Marriage Credit, Family Investment Credit, and Long-Term Care Partnership Credit. Use this tool to model how these can affect your annual return and potential refund.

Answers to common North Dakota filing questions, including federal conformity, credits, deductions, and part-year residency rules.

Does ND tax long-term vs short-term gains differently?

ND generally taxes gains at ordinary income rates—no separate state LTCG rate.

Does ND tax interest and dividends?

Yes—generally included unless a specific subtraction exists (e.g., certain U.S. obligations).

Any quick way to compare after-tax returns on investments?

Use CAGR, Compound Interest, and Bond Yield to size up pretax vs after-tax growth, then integrate the result with your ND net-pay plan.

How can I tune withholding to target a small refund?

Model your expected ND-1 liability on our page, then tweak “extra withholding” per paycheck until projected refund ≈ $0. Re-check after raises/bonuses and when changing 401(k)/HSA levels.

Are military salaries taxed by ND?

Active-duty pay for residents follows federal guidelines; ND offers specific subtractions/benefits in some cases—see ND-1SA.
