Nebraska Income Tax Calculator 2026

How Nebraska calculates your 2026 income tax

Nebraska starts with your federal adjusted gross income, subtracts the Nebraska standard deduction ($8,850 single, $17,700 joint, $12,950 head of household) or Nebraska itemized deductions, applies Schedule I adjustments, and then runs the result through the Tax Calculation Schedule. Nebraska itemized deductions equal your federal itemized deductions minus state and local income taxes.

After the tax is calculated, residents subtract a $176 personal exemption credit for each exemption — you, your spouse and each dependent. The credit is only for residents; part-year residents and nonresidents compute tax on Schedule III instead.

Worked example: $60,000 single filer

A single filer with $60,000 of federal AGI subtracts the $8,850 standard deduction for Nebraska taxable income of $51,150.

• Tax before credits: $2,026. Minus the $176 personal exemption credit: $1,850.
• Effective rate on AGI: 3.08%, compared with the 4.55% top marginal rate.
• The Department’s draft 2026 schedule shows the same result: a base amount plus 4.55% of the excess at each upper threshold.

Nebraska credits worth checking

Form 1040N has a long list of credits. These apply to the most households:

• Nebraska earned income credit: 10% of your federal earned income credit (refundable).
• Child and dependent care credit: refundable if your federal AGI is $29,000 or less; nonrefundable above that.
• Credit for tax paid to another state, using Nebraska Schedule II and a copy of the other state’s return.
• Adoption tax credit: 10% of your federal adoption credit.
• Credit for the elderly or disabled, based on federal Schedule R.
• Credit for community college property taxes paid (Form PTC).

Retirement income and Social Security

Social Security benefits are fully exempt from Nebraska income tax, so any benefits included in your federal AGI are subtracted on Schedule I. Pension, 401(k) and IRA distributions remain taxable unless a specific Schedule I subtraction applies, so check the Schedule I instructions before you file.

Filing deadlines and practical tips

The Nebraska return, Form 1040N, is due April 15. Most residents can e-file their original state return free through NebFile. Paper filers who file by April 15 and are owed a refund generally receive it by July 15.

• Line 59 asks for use tax on online or out-of-state purchases where sales tax was not collected, at the 5.5% state rate plus any local rate.
• Form 1040N asks for your federal filing status, so use the same status you used with the IRS.
• For 2027 the Department’s published estimated-tax schedule lowers the top rate to 3.99%, so plan withholding changes for next year.
