Nebraska Withholding Tax Rates: Brackets, W-4N, and Deposits

Nebraska’s withholding tax rates dropped for 2026 as the state’s scheduled rate reductions continued. The top individual income tax rate fell from 5.20% in 2025 to 4.55% for 2026, and every employer doing business in Nebraska must use the updated 2026 Circular EN tables to figure the correct amount to deduct from each paycheck.¹ The amounts withheld count as a credit against each employee’s annual state income tax liability.²

2026 Income Tax Brackets

Nebraska taxes income on a progressive schedule under Neb. Rev. Stat. § 77-2715.03, with four statutory brackets. For 2026, the top two brackets share the same rate. The base brackets for single filers, before annual inflation adjustments, are:³

2.46% on the first $3,000 of taxable income
3.51% on income from $3,000 to $18,000
4.55% on income from $18,000 to $29,000
4.55% on income above $29,000

For married couples filing jointly, the thresholds roughly double: 2.46% on the first $6,000, 3.51% from $6,000 to $36,000, 4.55% from $36,000 to $58,000, and 4.55% above $58,000.³

The bracket dollar amounts are adjusted annually for inflation, so the exact cutoffs shift slightly each year. The rates themselves are fixed by statute. Another reduction is already on the books: both rate three and rate four drop to 3.99% for taxable years beginning on or after January 1, 2027.³

How Employers Calculate Withholding

The statutory rates above set what an employee owes at year end. Payroll uses a separate set of tables designed to approximate that annual liability paycheck by paycheck. Those tables live in the Nebraska Circular EN, updated for wages paid on or after January 1, 2026.⁴ Employers pick one of two approaches.

Wage Bracket Method

The simpler option. Pre-calculated tables match pay ranges with the number of allowances the employee claimed on their W-4N. A payroll clerk finds the row for the gross wages, moves across to the column for the allowance count, and reads off the amount to withhold. Small employers running manual payroll usually prefer this.

Percentage Method

Better suited to automated systems. It starts by subtracting the value of the employee’s claimed allowances from gross pay, then applies graduated rates to what remains. For 2026, the value of one withholding allowance is:⁴

Weekly: $46.92
Biweekly: $93.85
Semimonthly: $101.67
Monthly: $203.33

After allowances are subtracted, the remaining wages run through a six-bracket rate schedule in the Circular EN. Those per-paycheck withholding rates don’t line up exactly with the statutory income tax rates because the tables build in assumptions about standard deductions and personal exemption credits so annual withholding lands close to actual tax owed.

Bonuses and Other Supplemental Wages

Bonuses, commissions, and other supplemental payments can be withheld two ways. The employer can combine them with the employee’s normal wages for the pay period and use the regular tables, or elect a flat 3.5% withholding rate on the supplemental amount.⁴ The flat rate keeps one-off payments simple but can underwithhold for higher earners whose effective rate sits closer to 4.55%.

Form W-4N and Allowances

Before any calculation, the employee needs to submit a Nebraska Withholding Allowance Certificate, Form W-4N. Nebraska stopped relying on the federal W-4 for state purposes on January 1, 2020, so every employee who completed a federal W-4 on or after that date also needs to file a W-4N.⁵ If no W-4N is on file, the employer must withhold as if the person were single with zero allowances, which takes the maximum amount from each check.⁶

One detail catches people out: head-of-household filers check the “Single” box on the form and then enter “1” on line 4e to indicate their head-of-household status.⁶ Employees can claim allowances for themselves, a spouse, and qualifying dependents. More allowances means less withholding per paycheck, which works if the allowances reflect the tax return that follows.

Nonresidents and Construction Contractors

Withholding reaches beyond traditional W-2 employees. Employers must withhold Nebraska income tax from nonresidents who perform services in the state, provided the wages are taxable under Nebraska law and subject to federal withholding. For nonresidents not covered by federal withholding rules, withholding kicks in once payments exceed $600 during the year if the employer has a Nebraska presence, or $5,000 if the employer has no office or business in the state.⁷

Independent contractors are generally exempt from standard income tax withholding. Construction is the exception. Any contractor paying another contractor for construction work performed in Nebraska must withhold 5% of the payment if the recipient isn’t listed in the Nebraska Contractor Database. Payments under $600 for the year are exempt.⁷ This one surprises general contractors the first time they hire subcontractors in the state.

Deposit and Filing Schedule

Once tax has been deducted, the employer holds the funds in trust until they’re due. Filing frequency depends on how much is withheld:

Monthly deposits are required whenever the employer withholds more than $500 during the first or second month of a calendar quarter. Deposits use Form 501N and are due by the 15th of the following month. Paying electronically eliminates the paper Form 501N.⁷
Quarterly returns on Form 941N are required from every employer withholding Nebraska income tax, due by the last day of the month following the quarter’s close.⁸
Annual filers, generally very small employers with minimal withholding, submit a single Form 941N covering the entire calendar year.

Most employers use the state’s online e-file system for both deposits and quarterly returns. Paper is still accepted, but processing takes longer.

Year-End W-2s and Form W-3N

By February 1 each year, employers must file copies of all employee W-2 forms with the Nebraska Department of Revenue along with a Nebraska Reconciliation of Income Tax Withheld, Form W-3N.⁸ Employers who issued more than 50 W-2s must e-file rather than send paper copies.¹ The same February 1 deadline and 50-form e-file threshold apply to Forms W-2G, 1099-MISC, 1099-NEC, and 1099-R.

Penalties for Late or Missing Payments

Falling behind gets expensive fast. An employer who withholds tax from paychecks but fails to remit it on time faces a 5% penalty on the unpaid amount, plus interest from the original due date until the balance is paid. If the penalty itself isn’t paid within 10 days of the Department’s notice, interest starts running on the penalty as well.⁹

The interest rate on delinquent Nebraska taxes for the period through December 31, 2026, is 8% per year, simple interest.¹⁰ Fraud raises the penalty to 50% of the unpaid amount. Willful evasion pushes it to 100%.⁹
