Who Must File a Nonresident Return in Bismarck?

North Dakota defines nonresidents as individuals who were not legal residents of the state for the entire 2026 tax year. This includes people who relocated to North Dakota mid-year, maintain a home outside the state while working in Bismarck, or own rental property or a business in the state while residing elsewhere. The key determining factor is your residency status on December 31, 2026.

For the 2026 tax year, nonresidents must file if they had gross North Dakota income from any source exceeding $4,050. This threshold applies across all income categories: W-2 wages from Bismarck employers, self-employment income from an online business serving North Dakota clients, rental income from property you own in the state, or investment income from North Dakota sources.

Key Situations Requiring Nonresident Filing

• You relocated to North Dakota during 2026 and lived there for part of the year.
• You work remotely for a Bismarck company but maintain your primary residence in another state.
• You own and operate a business in Bismarck but claim residency elsewhere.
• You have rental income from North Dakota properties and live out-of-state.
• You received severance or income from a Bismarck employer after moving out of state.

Residency Factors North Dakota Tax Authority Considers

North Dakota uses a multi-factor test to determine your residency status. The state examines your permanent home location, the location of your family, the state where you’re registered to vote, driver’s license state, and where you maintain social and business ties. For employees, the state may also consider where your employer is headquartered and whether you’re on temporary assignment. Business owners should note that operating a company in Bismarck typically means you have business owner filing obligations even if you live elsewhere.

What Are North Dakota Nonresident Income Tax Rates for 2026?

North Dakota’s income tax is progressive, meaning the rate increases with income. The 2026 tax brackets apply the same rates to nonresidents as they do to residents, though nonresidents only pay tax on income sourced to North Dakota. The lowest bracket begins at 2.9% for income under $7,025 (single) and applies to the first portion of your earnings, while the highest bracket of 5.84% applies to income exceeding $56,200. For married couples filing jointly, the brackets double, with the highest rate applying to income over $112,400.

The important distinction for nonresidents is that you calculate tax only on income from North Dakota sources. If you earned $50,000 in Bismarck and $20,000 from your home state, only the $50,000 is subject to North Dakota tax. This source-based taxation principle significantly benefits nonresidents who earn income both inside and outside the state. Use our Small Business Tax Calculator to estimate your 2026 North Dakota tax liability based on projected income.

2026 North Dakota Income Tax Brackets for Nonresidents

These 2026 rates reflect North Dakota’s current tax structure. The state has adopted certain provisions of the One Big Beautiful Bill Act (OBBBA), so nonresidents may also benefit from new tax strategy options like the Schedule 1-A deductions for tips and overtime income. Comparing your projected liability to what other states charge helps you understand whether Bismarck’s tax environment is favorable for your situation.

What Is the Income Threshold for Nonresident Tax Filing?

North Dakota’s filing threshold of $4,050 differs from the federal standard deduction of $16,100 (single) because the state uses a lower threshold to ensure broader compliance. If you earned $4,050 or more from North Dakota sources in 2026, you must file a nonresident return even if you don’t owe state tax after applying the standard deduction.

The $4,050 threshold applies to all nonresidents regardless of filing status, age, or income source. This includes independent contractors, remote workers, real estate investors, and business owners. The threshold includes all types of North Dakota income: W-2 wages, self-employment income from business operations, rental income from property you own in the state, capital gains from selling Bismarck real estate, and investment income from North Dakota sources.

Important Filing Threshold Details for Nonresidents

• The threshold applies only to your North Dakota income, not total income from all sources.
• You must file even if withholding covers your full tax liability.
• Filing a nonresident return is mandatory; the state doesn’t allow optional filing.
• Consider filing if you earned just below $4,050 if you had taxes withheld, as you may be entitled to a refund.

For real estate investors with rental properties in Bismarck, the filing threshold includes gross rental income, even if you have negative cash flow after expenses. This means you may need to file if your gross rent exceeds $4,050, requiring you to report your rental income and deductions on the nonresident return.

What Deductions Can Nonresident Filers Claim?

North Dakota allows nonresidents to claim deductions that reduce taxable income on Form ND-1. The primary deduction available to all nonresidents is the standard deduction, which for the 2026 tax year is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for heads of household. These deductions automatically reduce your North Dakota taxable income without requiring itemization.

Beyond the standard deduction, nonresidents can also claim business deductions if you’re self-employed, including home office expenses, equipment depreciation, professional service costs, and employee payroll. The self-employed nonresident can deduct half of self-employment tax, just like federal law allows. Additionally, if you paid income tax to another state on the same earnings, you can claim a credit for those taxes paid, preventing double taxation on the same income.

Common Deductions for Nonresident Filers in 2026

• Standard deduction: $16,100 (single) or $32,200 (married filing jointly).
• Business expenses: rent, utilities, supplies, professional services, insurance, advertising.
• Rental property deductions: mortgage interest, property tax, insurance, utilities, repairs, depreciation.
• Self-employment tax deduction: 50% of self-employment taxes paid to federal government.
• Foreign tax credit: if you have income from outside the U.S. and paid foreign taxes.
• Out-of-state tax credit: taxes paid to other states on the same income source.

2026 Schedule 1-A Deductions Available to Nonresidents

The new 2026 Schedule 1-A form introduced under the One Big Beautiful Bill Act provides additional deduction opportunities for nonresidents. If you earned tips as a Bismarck server or bartender, received qualified overtime compensation, or paid qualified auto loan interest, you may be eligible for these new deductions in addition to your standard deduction. These Schedule 1-A deductions reduce your federal taxable income and apply to your North Dakota return if the state has adopted the changes, which North Dakota as a Republican-led state has done for 2026.

North Dakota requires employers to withhold state income tax from nonresident employees’ paychecks based on the information provided on the federal Form W-4. Your withholding amount depends on your filing status, number of dependents, additional income, and other tax deductions you claim. Nonresidents should ensure their employer has accurate withholding information to avoid underpaying or overpaying state taxes during the year.

Many Bismarck employers use the federal W-4 calculation to determine state withholding because North Dakota conforms to federal withholding standards. However, if your personal tax situation is complex—such as working multiple jobs, having self-employment income, or receiving investment income—you may need to provide supplemental information to your employer for accurate state withholding. Nonresidents should also consider whether federal withholding adjustments will automatically flow through to state withholding calculations.

Managing Withholding as a Nonresident

• Update your W-4 if you have significant life changes (marriage, children, second job).
• Communicate with your employer if you’re a nonresident to ensure proper state coding.
• Use the IRS Tax Withholding Estimator (updated for 2026) to check if withholding is accurate.
• Request additional withholding if you expect to owe taxes beyond what’s being withheld.
• For self-employed income, make estimated quarterly payments to avoid underpayment penalties.

As a high-net-worth nonresident, review your withholding strategy quarterly. If you have income from multiple sources (W-2 wages, self-employment, rental income, dividends), the withholding from your W-2 job alone may not cover your total state tax liability. Adjusting withholding or making additional quarterly payments can prevent a large tax bill on April 15, 2027 when you file your 2026 return.

When Are Quarterly Tax Payments Due for Nonresidents?

Nonresidents with self-employment income, rental income, or significant investment income must file estimated quarterly tax payments with North Dakota. The state requires estimated payments if you anticipate owing more than $500 when you file your return. Quarterly payments help ensure you pay taxes throughout the year rather than facing a large bill on April 15, 2027.

The quarterly payment schedule follows the same federal calendar. Nonresidents should calculate estimated payments based on projected 2026 income and apply the appropriate North Dakota tax rate. If your income is irregular (for example, you expect a bonus in Q4 or plan to sell an investment property mid-year), adjust your quarterly payments to match projected income timing. This strategy prevents overpaying early in the year and underpaying later.

2026 Estimated Tax Payment Schedule for North Dakota Nonresidents

Which Forms Should You File as a Nonresident in Bismarck?

Nonresidents earning income in Bismarck must file the North Dakota Form ND-1, the state’s individual income tax return. This form is different from the resident form (Form ND-1 has a nonresident designation) and asks you to report only North Dakota source income. You’ll also need your W-2 forms from Bismarck employers and Schedule C (if self-employed), Schedule E (if you have rental income), or other income schedules depending on your income sources.

The filing deadline for 2026 nonresident returns is April 15, 2027, the same as federal returns. You can request an extension by filing Form 7004 before April 15, which extends your deadline to October 15, 2027. If you have complex business operations or own real estate generating rental income, ensure you file all supporting schedules with your nonresident return.

Forms and Documents You’ll Need to Gather

• Form ND-1 (North Dakota Nonresident Individual Income Tax Return).
• All Form W-2s from Bismarck employers (report Box 1 income on Form ND-1).
• Schedule C if self-employed (for business income from Bismarck operations).
• Schedule E if you have rental property income from North Dakota properties.
• Federal Schedule 1-A if claiming new 2026 deductions for tips, overtime, or auto interest.
• Documentation for out-of-state tax credits if you paid tax to other states.

Uncle Kam in Action: The Bismarck Remote Worker Tax Strategy

Sarah, a software developer, relocated from Minnesota to Bismarck in June 2026 to work for a tech startup. She earned $42,000 in W-2 wages from her Bismarck employer for the remainder of the year and maintained a small freelance client in Minnesota generating $8,000 in self-employment income. As a mid-year arrival, Sarah was considered a nonresident for 2026 tax purposes.

Sarah’s initial assumption was that she’d owe tax on all $50,000 of income. However, only her $42,000 from the Bismarck W-2 employer was subject to North Dakota tax. Her Minnesota self-employment income remained subject only to federal and Minnesota taxes. With the $16,100 standard deduction, Sarah’s North Dakota taxable income dropped to $25,900. Applying North Dakota’s progressive tax rates, her state income tax liability calculated to approximately $1,050 for the portion of the year. However, her Bismarck employer had withheld approximately $1,400 in North Dakota state income tax from her paychecks, resulting in a $350 refund on her 2026 nonresident return.

Additionally, Sarah discovered she could claim a credit for the Minnesota self-employment tax she paid. After applying this credit on her North Dakota Form ND-1, her refund increased to $425. The lesson: nonresidents benefit from only paying tax on state-source income and can optimize deductions and credits to minimize their overall tax burden. Uncle Kam’s strategic analysis identified that Sarah would reduce her combined state tax liability by $520 compared to filing as if all income were subject to North Dakota tax.

Tax Savings: $425 refund on North Dakota return plus $520 in optimized multi-state planning.

Investment: Tax consulting fees of $250.

First-Year ROI: 270% ($675 / $250).

Sarah’s experience demonstrates why nonresidents should seek professional tax planning before filing. The combination of understanding source-based taxation rules, correctly applying the standard deduction, and strategically using credits can dramatically improve your after-tax position. Contact Uncle Kam to explore your nonresident tax filing strategy and identify optimization opportunities in your specific situation.

Frequently Asked Questions

Can I file my nonresident return electronically in North Dakota?

Yes. North Dakota allows nonresidents to file Form ND-1 electronically through approved tax software or tax preparers. E-filing is often faster and more accurate than paper filing, and refunds typically process more quickly with electronic returns. You can also request an extension by filing Form 7004 electronically before April 15, 2027.

Do I need to file a North Dakota nonresident return if I’m a military member stationed in Bismarck?

Military members stationed in North Dakota generally must file as nonresidents for state tax purposes unless they have established legal residency in the state. However, certain tax benefits may apply to military income. Contact Uncle Kam or a military tax specialist for guidance on your specific situation, as military tax law has unique rules for active duty status.

What if I move out of North Dakota mid-year after establishing residency?

If you established legal residency in North Dakota during 2026 but moved out of state, you may be classified as a resident for part of the year or nonresident for part of the year. North Dakota uses a “resident for part of the year” status that taxes your income on a pro-rata basis. You may need to file a nonresident return reporting only the income earned during the months you lived in the state. Keep detailed records of when you moved to support your filing position.

How do I claim a credit for taxes paid to other states on the same income?

If you paid income tax to another state on the same earnings (for example, you worked part-year in Minnesota before moving to Bismarck), you can claim a credit on Form ND-1 to avoid double taxation. On the credit section of the nonresident return, report the amount of tax you paid to the other state. North Dakota generally allows a credit up to the lesser of the tax paid to the other state or your North Dakota tax liability on that same income. Proper documentation from your state 1040-NR or state return is essential.

Can I claim dependents on my North Dakota nonresident return?

Yes, you can claim dependents on Form ND-1 if they meet IRS qualifying dependent tests and you’re claiming them on your federal return. Generally, if your dependent lived with you for more than half the year (excluding temporary absences) and you provided more than half their financial support, you can claim them on your nonresident state return. Dependents provide additional tax benefits through child tax credits and dependent exemptions that reduce your state taxable income.

Is North Dakota nonresident income subject to self-employment tax?

Self-employment income earned in North Dakota as a nonresident is subject to both North Dakota state income tax and federal self-employment tax (Social Security and Medicare taxes). The North Dakota state income tax applies to your net self-employment earnings after deducting business expenses. Self-employment tax is assessed at the federal level and is calculated on Form SE of your federal return. You can deduct half of your self-employment tax on both your federal and state returns.

What is North Dakota’s penalty for failing to file a nonresident return?

If you fail to file a required North Dakota nonresident return by April 15, 2027, the state assesses a failure-to-file penalty of 5% per month (up to 25%) of your unpaid tax liability. Additionally, interest accrues daily on any unpaid taxes at the rate published by North Dakota monthly. If you realize you missed filing a prior year’s nonresident return, file immediately to minimize penalties and interest. Consider requesting a penalty waiver if you have reasonable cause for the late filing.
