How the Nebraska estimate works
Enter gross pay for one pay period, federal W-4 adjustments, and the state details shown above. Federal withholding follows Publication 15-T. Nebraska subtracts the 2026 pay-period value of each Form W-4N allowance, applies the Circular EN Single or Married percentage schedule, and adds the employee’s requested amount. When the more-than-24-employee special procedure applies and the result is below 1.5% of taxable wages, the calculator uses the selected official path: the Department’s 50% reference minimum, 1.5% of taxable wages, or a lower amount supported by documentation.
Example: For $525 of biweekly wages, Married status, and three allowances, the percentage method initially produces zero. Under the minimum-reference path, the 2026 table calculates withholding for Married with two allowances and uses 50% of that amount, producing a $0.25 minimum estimate; an employer using the separate 1.5% option would withhold $7.88. The calculator does not assume any unentered benefit deduction or invent a tax result.
Weekly, biweekly, semimonthly, and monthly are the supported paycheck frequencies. “Annual salary” is an earnings input and the annual view is a simple period multiplication; neither is an annual payroll-period method. The special Form W-4 adjustment for nonresident aliens is not modeled.
Why can Nebraska withholding exceed the normal table amount? Employers with more than 24 employees must review withholding below Nebraska’s special threshold. Without supporting employee documentation, Circular EN permits a minimum based on 50% of the Single-one-allowance or Married-two-allowance reference amount, or the employer may use 1.5% of taxable wages.
