Nebraska Income Tax Calculator, Rates and Brackets

2026 Nebraska Income Tax Calculator

How the Nebraska Income Tax Calculator Works

The Nebraska income tax calculator shows each major step from household income to estimated tax. The results compare Nebraska and federal income taxes, including differences in the treatment of standard and itemized deductions, tax credits, and deductions created by the One Big Beautiful Bill Act (OBBBA).

The final three rows summarize your Nebraska results:

• Estimated Income Tax: Your Nebraska income tax estimate for the year.
• Effective Tax Rate: Nebraska income tax as a percentage of household income.
• Marginal Tax Rate: The Nebraska tax rate applied to your next dollar of taxable income.

Nebraska Income Tax Rates

Nebraska uses a progressive individual income tax system, meaning different portions of taxable income may be taxed at different rates. The sections below present the inflation-adjusted Nebraska income tax rates and brackets for the 2026 tax year, for returns generally filed in 2027. They also explain how the rates apply to taxable income and provide step-by-step calculation examples for each filing status.

For 2026, Nebraska's top marginal individual income tax rate is 4.55%, down from 5.20% in 2025 under Legislative Bill (LB) 754. Nebraska still has four statutory income tax brackets listed in state law, but the third and fourth brackets share the same 4.55% rate. As a result, most taxpayers will see three distinct Nebraska income tax rates in the 2026 tables: 2.46%, 3.51%, and 4.55%.

Signed into law in 2023, LB 754 created a phased reduction in Nebraska income tax rates. State leaders have described the tax cuts as part of a broader effort to lower tax burdens, let residents keep more of their income, and make Nebraska more competitive for families and businesses.

Nebraska Income Tax Calculation Examples

The examples below start with household income and assume straightforward W-2 wage income, no dependents, age or blindness deductions, itemized deductions, or refundable credits. They apply Nebraska's standard deduction and personal exemption credit to estimate state income tax in each example. You can recreate these examples using the calculator above.

A common misconception is that reaching a tax bracket causes your entire income to be taxed at that rate. In both examples, only the taxable income within Nebraska's 4.55% bracket is taxed at 4.55%. The lower portions are taxed at 2.46% and 3.51%. The result is an effective tax rate of 2.35% in both examples. Next, we'll review the step-by-step calculations for the Single and Married Filing Jointly examples.

Step-by-Step Example 1: Single ($40,000 Household Income)

For a single filer with $40,000 of household income, Nebraska's 2026 standard deduction is $8,850. Subtracting that deduction leaves $31,150 of Nebraska taxable income.

That amount of taxable income reaches Nebraska's 4.55% bracket, so the marginal tax rate is 4.55%. The full $31,150 is not taxed at that rate. Instead, Nebraska applies each rate only to the portion of taxable income within that rate's bracket:

• Bracket 1 (The first $4,130): Taxed at 2.46%
  Calculation: $4,130 x 0.0246 = $101.60
• Bracket 2 ($4,130 to $24,760): The next $20,630 is taxed at 3.51%
  Calculation: $20,630 x 0.0351 = $724.11
• Bracket 3 (Over $24,760): The remaining $6,390 is taxed at 4.55%
  Calculation: $6,390 x 0.0455 = $290.75

Nebraska tax before credits: $101.60 + $724.11 + $290.75 = $1,116.46.

Nebraska personal exemption credit: As a single filer with no dependents, this example includes a $176 nonrefundable credit.

Nebraska income tax: $1,116.46 - $176 = $940.46.

Nebraska effective rate: 2.35%, calculated by dividing the estimated Nebraska tax of $940.46 by $40,000 of household income.

Nebraska marginal rate: 4.55% because the last dollar of taxable income falls within the 4.55% bracket.

Step-by-Step Example 2: Married Filing Jointly ($80,000 Household Income)

Now let's look at how the same system applies to a married couple filing jointly. Nebraska's Married Filing Jointly brackets are approximately twice the width of the corresponding Single brackets, and the joint standard deduction is twice the Single standard deduction. This structure avoids creating a state marriage tax penalty in a direct Single-versus-Married Filing Jointly bracket comparison.

For a married couple filing jointly with $80,000 of household income, Nebraska's 2026 standard deduction is $17,700. Subtracting that deduction leaves $62,300 of Nebraska taxable income.

That amount of taxable income reaches Nebraska's 4.55% bracket, so the marginal tax rate is 4.55%. The full $62,300 is not taxed at that rate. Instead, Nebraska applies each rate only to the portion of taxable income within that rate's bracket:

• Bracket 1 (The first $8,250): Taxed at 2.46%
  Calculation: $8,250 x 0.0246 = $202.95
• Bracket 2 ($8,250 to $49,530): The next $41,280 is taxed at 3.51%
  Calculation: $41,280 x 0.0351 = $1,448.93
• Bracket 3 (Over $49,530): The remaining $12,770 is taxed at 4.55%
  Calculation: $12,770 x 0.0455 = $581.04

Nebraska tax before credits: $202.95 + $1,448.93 + $581.04 = $2,232.92.

Nebraska personal exemption credit: As two taxpayers filing jointly with no dependents, this example includes a total nonrefundable credit of $352.

Nebraska income tax: $2,232.92 - $352 = $1,880.92.

Nebraska effective rate: 2.35%, calculated by dividing the estimated Nebraska tax of $1,880.92 by $80,000 of household income.

Nebraska marginal rate: 4.55% because the last dollar of taxable income falls within the 4.55% bracket.

Nebraska Income Tax Takeaways

Tax brackets do not apply to your entire income: The 4.55% marginal rate applies only to income above the applicable bracket threshold. Lower portions of taxable income remain taxed at Nebraska's lower rates, and the standard deduction reduces the amount of income that reaches the brackets in the first place.

The Single and Married Filing Jointly examples produce the same effective rate: Nebraska's joint-filer brackets, standard deduction, and personal exemption credit are approximately double the corresponding amounts for a single filer. As a result, the married couple earning $80,000 and the single filer earning $40,000 both produce a Nebraska effective tax rate of 2.35% in these examples.

Nebraska and federal taxable income are calculated differently: Nebraska uses its own standard deduction amounts, tax brackets, and personal exemption credit. It also does not apply every deduction available on the federal return. As a result, the same household income can produce different taxable income and effective tax rates in the Nebraska and federal columns of the calculator.

Nebraska's top income tax rate is decreasing: Legislative Bill 754 reduced Nebraska's top marginal individual income tax rate to 4.55% for 2026, down from 5.20% in 2025. Nebraska still has four statutory brackets, but the third and fourth brackets share the same 4.55% rate, producing three distinct rates. Under current law, the rates applied to those two upper brackets are scheduled to decrease to 3.99% beginning with the 2027 tax year.
