Nebraska bonus tax calculator
Your Nebraska bonus is ordinary income; the payday deduction is a flat withholding prepayment, not a higher rate. Nebraska adds a flat 3.5% on top of the 22% federal prepayment and FICA. Put in your figures above to compare what's withheld now with your real tax at filing — and the refund or shortfall. Everything runs in your browser.
Short version: in Nebraska, a bonus paid on its own is withheld at the flat federal 22%, 3.5% for Nebraska, and 7.65% FICA. None of that is the final number — a bonus is taxed at your marginal rate once you file, so the calculator above estimates what comes back or is still due.
Estimate only, not tax advice — terms.
What a $18,000 bonus really costs on a $36,000 Nebraska income
Take a single filer in Nebraska earning $36,000 who gets a $18,000 bonus on its own check:
- Withheld now: $3,960 federal (22%) + $630 Nebraska + $1,377 FICA = $5,967 held back, leaving about $12,033 in hand — a 33.1% bite.
- At tax time: the bonus's actual income tax works out near $2,979 (federal $2,160 + Nebraska $819) — and FICA is the same $1,377 as before.
- The gap: you over-paid income tax by roughly $1,611, and that returns as a refund at filing. Either way, the $1,377 FICA is final and won't come back.

What Nebraska holds back on a $5,000, $25,000, or $100,000 bonus
Three bonuses — $5,000, $25,000, $100,000 — and what Nebraska withholds from each on a $70,000 salary:
| Bonus | Federal | Nebraska | FICA | Total | % of bonus |
|---|---|---|---|---|---|
| $5,000 | $1,100 | $175 | $383 | $1,658 | 33.1% |
| $25,000 | $5,500 | $875 | $1,913 | $8,288 | 33.1% |
| $100,000 | $22,000 | $3,500 | $7,650 | $33,150 | 33.1% |
The rate drifts as Social Security hits its annual cap, but the income-tax part still reconciles at filing.
What comes out of a Nebraska bonus in 2026
The 22% isn't a bonus tax. It's the flat rate an employer may use to withhold federal income tax from a separately paid bonus (IRS Pub 15). A mandatory 37% hits supplemental pay beyond $1,000,000 a year; neither figure is a special "bonus" rate, both are withholding defaults.
Nebraska keeps it simple: 3.5%. A separately paid bonus is subject to one flat state rate in Nebraska, 3.5% (Nebraska DOR Circular EN).
Set FICA aside as final. The 7.65% FICA bite is the tax itself — Social Security stops at the annual wage base, Medicare doesn't. It reads the same in the "now" and "at tax time" columns because none of it comes back — just the income-tax slice is a prepayment that reconciles.

Is Nebraska's a flat 3.5% bonus rate a "bonus tax"? No
There is no special bonus tax rate. The 22% is a withholding convenience; at filing the bonus is taxed like the rest of your income, at your marginal rate across the brackets. Below a 22% real rate you get money back; above it, you settle the gap at filing. Worked out for the $18,000 bonus here, about $1,611 returns as a refund. Only FICA (7.65%) is a true tax that never returns.
Cross-border check: Nebraska vs. Iowa, Kansas and Colorado on a bonus
A single filer earning $70,000 who gets a $10,000 bonus, in Nebraska and neighboring Iowa, Kansas and Colorado:
| State | Bonus method | State withheld | Total withheld |
|---|---|---|---|
| Nebraska | flat 3.5% | $350 | $3,315 |
| Iowa | flat 3.8% | $380 | $3,345 |
| Kansas | flat 5% | $500 | $3,465 |
| Colorado | aggregate (~4.4%) | $440 | $3,405 |
Each total adds the flat federal 22%, the state amount, and FICA; single-filer estimates that true up at filing time.
Nebraska bonus tax FAQ
Why might I owe tax on my Nebraska bonus at filing?
Because 22% is only a prepayment. If your true marginal rate is above 22% (high earners), the flat withholding falls short and you owe the rest; below 22%, you're over-withheld and get money back.
Does a bonus push my Nebraska income into a higher bracket?
No. Brackets are marginal — only the dollars above each threshold are taxed higher. A bonus never re-taxes income you already earned.
Does Nebraska tax bonuses more than regular pay?
No. There's no separate, higher tax on bonuses — a bonus is just withheld at a flat rate up front, then taxed like any income at your marginal rate.
How much is withheld from a bonus in Nebraska for 2026?
On a separately paid bonus, Nebraska takes 3.5%, the federal side takes a flat 22% (37% beyond $1,000,000/yr), and FICA takes 7.65%. Those are withholding rates that settle up when you file — not a final tax.
