How much do I take home in North Dakota? — short answer first

North Dakota simplified its individual income tax under HB 1158 (2023), collapsing the previous 5-bracket progressive structure into a clean 3-bracket schedule effective tax year 2024+: 0% on the first $44,725 (single) / $74,750 (joint), 1.95% middle band, 2.5% top. The 2.5% top rate is among the lowest in the US for states with income tax (behind only Indiana's 2.95% projected). Standard deduction conforms to federal ($14,600 single / $29,200 joint). Combined with the 0% bottom bracket on the first ~$45K single, the effective tax burden for most working adults is among the lowest in the US. Reciprocity with Minnesota and Montana.

The North Dakota take-home pay formula

net_pay     = gross − federal_tax − fica − state_tax − local_tax − pre_tax
federal_tax = Σ (federal_bracket × rate) on (gross − std_dev − 401k − hsa)
fica        = MIN(wages, $181K) × 6.2% + wages × 1.45% + add'l Medicare
state_tax    = Σ (bracket_amount × bracket_rate)    // top rate 2.50% in North Dakota
local_tax    = 0    // no local payroll tax in North Dakota

The 2026 take-home calculation for North Dakota stacks four mandatory deductions: federal income tax (7-bracket progressive), FICA (Social Security capped at $181K + uncapped Medicare), North Dakota state income tax (3-bracket progressive, top rate 2.50%). Pre-tax 401(k) and HSA reduce federal taxable income; HSA additionally reduces FICA wages.

How North Dakota taxes payroll in 2026

North Dakota levies a 3-bracket progressive individual income tax under N.D.C.C. §57-38-30.3 effective tax year 2024+. Single filer brackets: 0% on the first $44,725 of taxable income; 1.95% on $44,726-$225,975; 2.5% above $225,975. Married-filing-jointly thresholds: 0% to $74,750; 1.95% to $275,100; 2.5% above. The simplified 3-bracket structure replaced North Dakota's previous 5-bracket progressive schedule under HB 1158 (2023). Critically, the 0% bottom bracket extends to $44,725 (single) — meaning a single filer earning $40,000 of taxable income pays $0 in North Dakota state tax. Combined with the federal-conforming standard deduction ($14,600 single, indexed), a single filer with $55,000 gross income (after standard deduction $14,600 = $40,400 taxable) pays $0 in ND state tax. This makes North Dakota effectively a no-income-tax state for most working adults at typical Midwest wage levels. The 2.5% top rate (kicks in at $225,975 single) is among the lowest in the US for states with income tax — behind only Indiana's 2.95% projected for 2026 and Pennsylvania's 3.07% flat. North Dakota has no local income tax — Fargo, Bismarck, Grand Forks, Minot, and West Fargo all fund services through property tax (effective rate ~0.94% statewide — below national average) and 5% state sales tax + up to 3% local (Fargo combined 7.5%, Bismarck combined 7%). North Dakota maintains reciprocity with Minnesota and Montana — narrow but useful for cross-border workers in the eastern ND / western MN plains and the western ND / eastern MT region. ND residents working in MN or MT file solely the ND return; the working state does not withhold.

How to use this calculator

Enter your annual gross salary. Pre-tax, what your employer pays before any deductions.
Pick filing status. Single, married filing jointly, married filing separately, or head of household. Drives both federal and North Dakota brackets.
Add 401(k) and HSA contributions (optional). Both lower your federal taxable income; HSA also lowers FICA wages.
Read the verdict. Annual + monthly + bi-weekly take-home, federal + state + local breakdown, and effective tax rate.

Common mistakes

Confusing gross with adjusted gross. The calculator wants your gross salary — what your employer pays before any pre-tax deductions or contributions. If you enter your W-2 Box 1 (already net of 401k), the math will under-count your tax.
Forgetting that 401(k) is still subject to FICA. Traditional 401(k) reduces federal income tax but NOT Social Security + Medicare. Only HSA (through payroll) reduces both.
Using the wrong filing status for state tax. North Dakota uses the same filing status categories as the IRS, but bracket thresholds differ from federal. Pick the status that matches your actual tax filing — not just what gives the best number.
Ignoring multi-state implications. If you work in North Dakota but live elsewhere (or vice versa), you may owe taxes in both states with a credit between them. This calculator assumes you both live and work in North Dakota.

Quick reference

Payroll terminology — applies to North Dakota

Gross Salary The headline number from your offer letter, before any deductions. The starting point for every paycheck calculation.: Lenders, landlords, and benefit calculations use gross. Always confirm whether a quoted figure is gross or net — the gap is typically 25-40% in the US once federal + FICA + state are stacked.
Net Take-Home Pay What lands in your bank account after federal + FICA + state + local + pre-tax deductions. The number to budget against.: For North Dakota: gross − federal − FICA − North Dakota state income tax − 401(k) − HSA.
FICA Federal Insurance Contributions Act — payroll tax funding Social Security (6.2% to $181K) + Medicare (1.45%, no cap). 7.65% combined.: Additional Medicare 0.9% applies above $200K single / $250K MFJ. Thresholds frozen since 2013, so an increasing share of earners hit it each year. HSA contributions (but NOT 401k) reduce FICA wages.
Source: SSA — Wage base & tax rates
Marginal Tax Rate The rate applied to your NEXT dollar of income. Drives the cost of a raise, bonus, or extra 401(k) contribution.: In North Dakota, your combined marginal rate stacks federal (12-37%) + FICA (1.45-2.35%) + North Dakota state (0.0%-2.5%). A six-figure earner often faces a 35-45% marginal rate.
Effective Tax Rate Total tax divided by gross income. The actual percentage of your salary that disappears to tax — always lower than marginal.: Two earners at the same gross can have different effective rates depending on pre-tax contributions. Use effective rate for affordability comparisons; use marginal for raise / bonus decisions.
Standard Deduction Fixed amount subtracted from gross before federal brackets apply. 2026: $15,750 single · $31,500 MFJ · $23,625 HoH.: North Dakota's state standard deduction (single) is $14,600 — applied independently before state brackets. Federal and state standard deductions stack; you do not have to itemize on one to claim the other.
Source: IRS Rev. Proc. 2024-40
Pre-Tax Deductions Amounts subtracted from gross BEFORE income tax is computed — 401(k), traditional IRA via payroll, HSA, FSA, employer health premiums.: Reduces federal taxable income dollar-for-dollar. HSA also reduces FICA wages (the 'triple advantage'). Traditional 401(k) reduces federal tax but NOT FICA — Roth 401(k) reduces neither but grows tax-free.
North Dakota State Tax Progressive 3-bracket state income tax. Top rate 2.50%. Filed on North Dakota Office of State Tax Commissioner.: Brackets refresh annually — most state DORs publish updates in Q4 preceding the tax year. North Dakota's structure progresses through 3 brackets, with separate filing-status schedules for MFJ and HoH.
