New Jersey bonus tax calculator
Your New Jersey bonus is ordinary income; the payday deduction is a flat withholding prepayment, not a higher rate. New Jersey has no separate bonus rate, so it withholds using the aggregate method on top of the 22% federal prepayment and FICA. New Jersey also withholds disability insurance, paid family leave, unemployment insurance and workforce development contributions from wages, which this estimate does not model. Enter your numbers to see what's held back now beside what the bonus will really cost when you file, and your refund or amount owed. Everything runs in your browser.
Short version: in New Jersey, a bonus paid on its own is withheld at the flat federal 22%, no separate New Jersey rate — it's withheld as ordinary wages, and 7.65% FICA. That's a prepayment, not your final tax — the bonus is really taxed at your marginal rate when you file, and the calculator above shows the refund or amount you'll owe. New Jersey also withholds disability insurance, paid family leave, unemployment insurance and workforce development contributions from wages, which this estimate does not model.
Estimate only, not tax advice — terms.
The "New Jersey bonus tax" myth, and what's really withheld
The 22% you see isn't a bonus levy; it's a withholding placeholder. Your bonus is ordinary income, and its real tax is whatever your marginal rate works out to across the brackets. Below a 22% real rate you get money back; above it, you settle the gap at filing. On the $24,000 example below, roughly $2,410 is over-withheld and comes back to you at filing. The lone exception is FICA (7.65%), which is a real tax rather than a prepayment.
New Jersey vs. New York, Pennsylvania and Delaware: bonus withholding compared
Take a $10,000 bonus for someone on $70,000 and compare New Jersey with bordering New York, Pennsylvania and Delaware:
| State | Bonus method | State withheld | Total withheld |
|---|---|---|---|
| New Jersey | aggregate method | $586 | $3,551 |
| New York | flat 11.7% | $1,170 | $4,135 |
| Pennsylvania | aggregate (~3.07%) | $307 | $3,272 |
| Delaware | aggregate method | $660 | $3,625 |
Figures are the 22% federal plus state plus FICA for a single filer; the income tax you owe reconciles on your return.
How a New Jersey bonus is withheld: 22% federal + the aggregate method
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.
New Jersey folds the bonus into regular pay. Lacking a flat supplemental rate, New Jersey uses the aggregate method: withholding is figured on your wages plus the bonus. New Jersey's income tax is graduated across seven New Jersey brackets topping out at 10.75%, so an aggregated bonus is withheld somewhere along that schedule. New Jersey also withholds disability insurance, paid family leave, unemployment insurance and workforce development contributions from wages, which this estimate does not model. The published rates do not say whether a separately paid bonus carries them, so your pay stub is the authority there.
Don't expect FICA back. Of the total held back, 7.65% is FICA — Social Security to the wage base, plus Medicare — owed at that rate. Neither piece refunds at filing, so both columns of the tool show it unchanged; the income-tax withholding is the only part that trues up.

What a $24,000 bonus really costs on a $28,000 New Jersey income
Here's how a $24,000 bonus plays out for a single filer making $28,000 in New Jersey:
- Withheld now: $5,280 federal (22%) + $923 New Jersey + $1,836 FICA = $8,039 held back, leaving about $15,961 in hand — a 33.5% bite.
- The real bill: at filing the bonus is taxed roughly $3,793 in income tax (federal $2,870 + New Jersey $923), with the identical $1,836 FICA on top.
- The gap: you over-paid income tax by roughly $2,410, and that returns as a refund at filing. Either way, the $1,836 FICA is final and won't come back.

How New Jersey withholding scales from a $5,000 to a $100,000 bonus
Three bonuses — $5,000, $25,000, $100,000 — and what New Jersey withholds from each on a $70,000 salary:
| Bonus | Federal | New Jersey | FICA | Total | % of bonus |
|---|---|---|---|---|---|
| $5,000 | $1,100 | $276 | $383 | $1,759 | 35.2% |
| $25,000 | $5,500 | $1,542 | $1,913 | $8,954 | 35.8% |
| $100,000 | $22,000 | $6,319 | $7,650 | $35,969 | 36.0% |
That percentage moves once Social Security caps out at the wage base, and the income-tax slice still settles at filing.
New Jersey bonus tax FAQ
How much is withheld from a bonus in New Jersey for 2026?
On a separately paid bonus, New Jersey takes the aggregate method, 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. New Jersey also withholds disability insurance, paid family leave, unemployment insurance and workforce development contributions from wages, which this estimate does not model.
Is a New Jersey bonus taxed differently from my salary?
Not in the end. It may be withheld differently (a flat rate up front), but at filing a bonus is taxed exactly like the rest of your income, at your marginal rate.
Why might I owe tax on my New Jersey 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 New Jersey have a separate bonus withholding rate?
No. New Jersey has no separate supplemental rate, so a bonus is withheld with the aggregate method — as if it were part of your regular wages.
