Nebraska’s state income tax is a progressive tax on individual earnings, with 2026 rates of 2.46%, 3.51%, and 4.55% applied in brackets to your taxable income. The Nebraska Department of Revenue administers the tax, which starts from your federal adjusted gross income and then applies state-specific additions, subtractions, deductions, and credits to arrive at what you owe.
2026 Rates and Brackets
Three rates apply for the 2026 tax year:
- 2.46% on income in the first bracket
- 3.51% on income in the second bracket
- 4.55% on all income above the second bracket
What used to be four distinct rates has effectively compressed to three, because ongoing reductions under LB 754 pulled the top two rates together at 4.55% for 2026.1Nebraska Legislature. Nebraska Revised Statute 77-2715.03 – Individual Income Tax Brackets and Rates The base thresholds in statute begin at $3,000 for single filers and $6,000 for married couples filing jointly, but the Tax Commissioner adjusts those figures annually for inflation. For the exact bracket cutoffs on your return, look at the Form 1040N instruction booklet when you file.
The compression is temporary. In 2027, both of the upper rates drop again to 3.99%, completing the schedule set by LB 754.2Nebraska Legislature. Legislative Bill 754 Because the tax is progressive, every filer pays 2.46% on their first few thousand dollars before any higher rate kicks in, even those whose top dollar lands in the 4.55% bracket.
Who Has to File
You must file a Nebraska return if you were required to file a federal return, or if your Nebraska addition adjustments to federal AGI total $5,000 or more. The form you use depends on your residency during the year.
Nebraska treats you as a resident if you are domiciled in the state, even while temporarily away, or if you keep a permanent place of abode in Nebraska and are physically present there more than six months during the year.3Cornell Law School. 316 Neb. Admin. Code, ch. 22, 001 – Definition of Resident Individual Domicile turns on where you intend to return, not just where you happen to be at any given moment.
Nonresidents owe Nebraska tax on income from Nebraska sources, such as wages from a Nebraska employer or rent from Nebraska property. Part-year residents apportion income based on the time they lived in-state. If you’re a full-year resident who already paid income tax to another state on the same income, Schedule II of Form 1040N provides a credit so you aren’t taxed twice.4Nebraska Department of Revenue.

How Your Taxable Income Is Calculated
Your Nebraska taxable income starts with the federal AGI from your federal return. From there, Schedule I handles the state’s required additions and subtractions.5Nebraska Legislature. Individual Income Tax
The addition most individual filers encounter is interest on state and local bonds issued outside Nebraska: if you held municipal bonds from another state and the interest was excluded federally, Nebraska adds it back. On the subtraction side, interest from U.S. government obligations such as Treasury bills, savings bonds, and federal agency securities comes out of your Nebraska income. States are federally required to exempt that interest, and Nebraska lists it as a specific subtraction.6Nebraska Department of Revenue. Chapter 22 – Individual Income Tax
Standard Deduction or Itemize
After adjustments, you choose between Nebraska’s standard deduction and itemizing. The state standard deduction is substantially smaller than the federal one, running roughly $2,700 for single filers and $5,400 for joint filers in 2026. If your qualifying expenses (mortgage interest, state and local taxes, charitable gifts) exceed those amounts, itemizing is usually the better move.
Retirement Income
Social Security benefits are fully exempt from Nebraska income tax. The state completed a phased elimination, so for the 2026 tax year you owe nothing to Nebraska on Social Security no matter your total income.
Military retirement pay is also 100% exempt for tax years beginning on or after January 1, 2022. If you receive a pension reported on a 1099-R from the Department of Defense or the Office of Personnel Management, you can subtract the entire amount from your Nebraska taxable income.7Nebraska Legislature. Legislative Bill 1394
529 Plan Contributions
Contributions to a Nebraska Educational Savings Trust (NEST) 529 plan can be deducted up to $10,000 per year, or $5,000 if married filing separately. Amounts above the cap do not carry forward.8Official Nebraska Government Website. Governor Pillen Highlights the Importance of Education Savings The deduction is for NEST only. Contributions to another state’s 529 plan don’t qualify.
Credits That Reduce What You Owe
Earned Income Tax Credit
Nebraska’s state EITC is refundable and equal to 20% of your federal EITC. If you qualify federally, you qualify at the state level. Because the credit is refundable, it can generate a refund even if you owe no Nebraska tax.9Nebraska Legislature. LR126 (2025)
Child Care Refundable Credit
Parents or legal guardians of children age five or younger may claim a refundable child care credit under LB 754, effective for tax years beginning on or after January 1, 2024. The amount is tied to total household income (federal modified AGI):
- $2,000 per child if household income is $75,000 or less
- $1,000 per child if household income is between $75,001 and $150,000
Households above $150,000 are not eligible.10Nebraska Department of Revenue. Child Care Refundable Tax Credit
Community College Property Tax Credit
If your property tax bill included a community college levy, Form PTC filed with your income tax return gives you a credit for that portion of the bill. It applies only to the community college share, not the full property tax. You will need parcel ID numbers and the county for each property.11Nebraska Department of Revenue. Nebraska Property Tax Credit 2025
Filing Deadline and Extensions
Individual returns for tax year 2025 are due April 15, 2026. When the date falls on a weekend or legal holiday, the deadline rolls to the next business day. Farmers and ranchers who did not make estimated payments during the year must file and pay in full by March 2, 2026.12Nebraska Department of Revenue. Nebraska Tax Calendar
You can request an automatic six-month extension by filing Form 4868N before the original due date. The catch that trips people up: an extension gives you more time to file, not more time to pay. Interest accrues on any unpaid balance from the original due date forward, so sending a tentative payment with the extension stops interest from building on that amount.13Nebraska Department of Revenue. Nebraska Application for Automatic Extension of Time to File a Nebraska Individual Income Tax Return
If you already have a federal extension, Nebraska automatically extends your state deadline for the same period. You don’t file a separate Form 4868N, but when you submit your Nebraska return, attach a copy of your federal Form 4868 or include your federal electronic confirmation number.13Nebraska Department of Revenue. Nebraska Application for Automatic Extension of Time to File a Nebraska Individual Income Tax Return
How to File
Nebraska uses Form 1040N as its individual return. Because it draws heavily from your federal return, have your completed federal 1040, W-2s, and any 1099 forms in front of you before you start.14Nebraska Department of Revenue. Nebraska Individual Income Tax Return – Form 1040N You will also use Schedule I for additions and subtractions, Schedule II if you’re claiming a credit for taxes paid to another state, and Schedule III if you’re a nonresident or part-year resident.4Nebraska Department of Revenue. Individual Income Tax Forms
Electronic filing is the fastest route. NebFile, the state’s free e-filing portal, handles Form 1040N along with Schedules I and II for residents.15Nebraska Department of Revenue. NebFile for Individuals Commercial tax software that supports Nebraska can also e-file through the combined federal/state system, and refunds on e-filed returns typically arrive within a few weeks.16Nebraska Department of Revenue.

Paper returns go to Lincoln, with two addresses depending on whether a payment is included. Returns without a payment: PO Box 98912, Lincoln, NE 68509-8912. Returns with a payment: PO Box 98934, Lincoln, NE 68509-8934.17Nebraska Department of Revenue. Contact Us Paper filing takes considerably longer, especially at the height of the season. You can check refund status on the Department of Revenue’s website regardless of how you filed.
Estimated Tax Payments
If your expected Nebraska tax liability after withholding and credits will be $300 or more, you must make quarterly estimated payments using Form 1040N-ES.18Cornell Law School. 316 Neb. Admin. Code, ch. 20, 001 – Payment of Estimated Tax: Individuals This usually applies to self-employed workers, landlords, and anyone with substantial income that isn’t subject to employer withholding. Missing estimated payments can lead to underpayment penalties on top of the tax owed, so keep an eye on the $300 threshold if your income shifts mid-year.
Penalties and Interest for Late Filing or Payment
Filing late without reasonable cause triggers a penalty of 5% of the unpaid tax for each month the return is overdue, capped at 25%.19Nebraska Legislature. Nebraska Revised Statutes 77-2789 – Income Tax; Failure to File The percentage is calculated on tax still owed at the due date, so paying as much as you can by April 15 trims the penalty even if the return itself isn’t ready.
Interest runs separately. For 2025 through 2026, Nebraska charges 8% annual interest on delinquent tax, accruing from the original due date until the balance is paid in full.20Nebraska Department of Revenue. Revenue Ruling 99-24-1 – Interest Rate Assessed on State Taxes Interest and the late filing penalty stack. A return that is both late and unpaid builds up charges quickly. You can request abatement of the penalty if you can show reasonable cause rather than willful neglect, but interest still applies.19Nebraska Legislature. Nebraska Revised Statutes 77-2789 – Income Tax; Failure to File
Amending a Nebraska Return
Starting with tax year 2025, you amend a Nebraska return by filing a new Form 1040N and checking the box marking it as amended. Commercial tax software that supports Nebraska e-filing can submit the amended return electronically. NebFile cannot: it handles original returns only.21Nebraska Department of Revenue. Tips for Filing a Nebraska Amended Individual Income Tax Return
For tax years 2024 and earlier, you must file a paper Form 1040XN and mail it in. If your Nebraska amendment follows a federal amendment filed past the three-year statute of limitations, wait until you have proof the IRS accepted the federal change before sending the state version.21Nebraska Department of Revenue.
