How a Nebraska paycheck works
Nebraska keeps a graduated schedule with six rate steps above a zero band, and the steps are close together, so the marginal rate climbs steadily rather than jumping. Withholding follows the state's own percentage tables: subtract a fixed amount for each allowance claimed on the state certificate, then read the annual table for single or married employees.
Federal income tax withholding
Federal withholding annualises the wage, subtracts the standard deduction for the filing status on Form W-4 Step 1, applies the graduated schedule for that status, and deducts the dependent credit from Step 3. This page models a W-4 with Steps 2 and 4 blank: one job, no spouse income, no other income, no extra withholding.
Social Security and Medicare
Social Security takes a flat rate on wages up to an annual ceiling that moves each year. Medicare applies to every dollar, and above a fixed threshold the employer withholds the Additional Medicare tax on the excess.
Two tables and one allowance
Nebraska publishes a single table and a married table. Head of household is folded into the single table and surviving spouse into the married one, so there are only two columns in practice. Every allowance claimed on the state certificate removes the same fixed amount from the annual wage before the table applies, and the value of one allowance is published each year alongside the tables.
The schedule's zero band means a wage below a modest threshold, after allowances, produces no state withholding. Above that the rate rises through several closely spaced steps, so the effective rate climbs smoothly across most of the salary range and flattens near the top.
Local income tax
No Nebraska city or county taxes wages. Omaha and Lincoln have the same payroll deductions as the rest of the state.
What the employer pays on top
The employer matches Social Security and Medicare and pays federal unemployment tax at its net rate. Nebraska unemployment insurance is an employer contribution at an experience-rated percentage on a state wage base. There is no employee-side state levy.
What this calculator assumes
The figure models a salaried employee paid evenly across the year with a standard Form W-4 and state certificate, and no pre-tax deductions. It leaves out:
- Pre-tax contributions such as a 401(k), health premiums, HSA or flexible spending accounts.
- Extra withholding requested on the federal or state certificate, and the W-4 Step 2 and Step 4 adjustments.
- Bonuses and other supplemental wages, which may be withheld at a flat supplemental rate.
- Employer-side state unemployment insurance, which is priced per employer.
- Employees outside the normal Social Security system, such as some public-sector staff and certain visa holders.
Withholding versus your final tax bill
Withholding is a prepayment. The federal and state returns replace these assumptions with your real situation: itemised deductions, other income, and credits payroll knows nothing about. One job usually produces a refund; two jobs or a working spouse often produce a balance due.
