About the North Dakota Income Tax Calculator
The North Dakota Income Tax Calculator gives you an instant answer from just a few inputs — filing status, gross annual income, pre-tax deductions (401(k), hsa, premiums). It runs entirely in your browser, so the numbers you enter stay private and never touch a server, and the result recalculates the moment you change a value. It's free to use with no sign-up, no limits, and nothing to install.
Worth Knowing
North Dakota runs a progressive income tax with 3 brackets, starting at 0% on the first $48,475 of taxable income and topping out at 2.5% on income above $244,825 for a single filer. As with federal tax, each rate applies only to the slice of income inside its own bracket — reaching the top rate does not retroactively tax your earlier dollars at that rate, which is why the effective rate this calculator reports always lands below your marginal rate. Before any of those rates apply, North Dakota subtracts a standard deduction of $16,100 for single filers and $32,200 for joint filers. Joint filers also get wider brackets, so a couple with one income usually pays less than two single filers splitting the same total. This estimate covers state income tax, federal income tax, and FICA on wage income using 2026 figures. It does not model city or county income taxes, tax credits, itemized deductions, self-employment income, or part-year residency — if you moved into or out of North Dakota during the year you will generally file a part-year return and allocate income between states rather than paying full-year tax to either. Treat the result as a planning estimate and confirm anything you file with the North Dakota tax authority or a qualified tax professional.
