Delaware bonus tax calculator
Got a bonus in Delaware? It isn't taxed at a special rate — what shrinks it is withholding. Delaware has no separate bonus rate, so it withholds using the aggregate method on top of the 22% federal prepayment and FICA. Delaware also withholds paid family leave contributions from wages, which this estimate does not model. Drop your figures in to watch the payday deduction sit next to the real filing cost, plus whatever you get back or owe. Everything runs in your browser.
The quick take: a stand-alone Delaware bonus has a flat 22% federal tax withheld, no separate Delaware rate — it's withheld as ordinary wages, plus 7.65% FICA. But that's only withholding. Your real bill is your marginal rate at filing; run the calculator to see the refund or shortfall. Delaware also withholds paid family leave contributions from wages, which this estimate does not model.

A $9,000 bonus on a $61,000 Delaware salary: withheld vs. actually owed
Picture a Delaware worker on a $61,000 salary handed a $9,000 bonus, paid on its own:
- Withheld now: $1,980 federal (22%) + $570 Delaware + $689 FICA = $3,239 held back, leaving about $5,761 in hand — a 36.0% bite.
- The real bill: at filing the bonus is taxed roughly $2,000 in income tax (federal $1,430 + Delaware $570), with the identical $689 FICA on top.
- The gap: you over-paid income tax by roughly $550, and that returns as a refund at filing. The $689 FICA doesn't move — that part is owed no matter what.

Delaware vs. Maryland, Pennsylvania and New Jersey: bonus withholding compared
A single filer earning $70,000 who gets a $10,000 bonus, in Delaware and neighboring Maryland, Pennsylvania and New Jersey:
| State | Bonus method | State withheld | Total withheld |
|---|---|---|---|
| Delaware | aggregate method | $660 | $3,625 |
| Maryland | flat 6.5% | $650 | $3,615 |
| Pennsylvania | aggregate (~3.07%) | $307 | $3,272 |
| New Jersey | aggregate method | $586 | $3,551 |
Each total adds the flat federal 22%, the state amount, and FICA; single-filer estimates that true up at filing time.
Delaware bonus withholding, piece by piece
The federal side is a flat prepayment. A bonus on its own check has 22% withheld for federal income tax (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.
Delaware folds the bonus into regular pay. Lacking a flat supplemental rate, Delaware uses the aggregate method: withholding is figured on your wages plus the bonus. Delaware's income tax is graduated across seven Delaware brackets topping out at 6.6%, so an aggregated bonus is withheld somewhere along that schedule. Delaware also withholds paid family leave contributions from wages, which this estimate does not model. The published rate does not say whether a separately paid bonus carries it, 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. 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 Delaware's the aggregate method 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. In this page's $9,000 example, about $550 of what's withheld is really over-payment you'd get back. Set aside the 7.65% FICA — that part is owed for good and never refunds.
What Delaware holds back on a $5,000, $25,000, or $100,000 bonus
What's held back from three bonus sizes in Delaware (single filer, $70,000 salary):
| Bonus | Federal | Delaware | FICA | Total | % of bonus |
|---|---|---|---|---|---|
| $5,000 | $1,100 | $330 | $383 | $1,813 | 36.3% |
| $25,000 | $5,500 | $1,650 | $1,913 | $9,063 | 36.3% |
| $100,000 | $22,000 | $6,600 | $7,650 | $36,250 | 36.3% |
The rate drifts as Social Security hits its annual cap, but the income-tax part still reconciles at filing.
Delaware bonus tax FAQ
Why might I owe tax on my Delaware 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.
Are bonuses taxed at a higher rate in Delaware?
No. A bonus is ordinary income taxed at your normal marginal rate when you file; the flat 22% withheld is a prepayment, not a tax rate.
What is the Delaware bonus tax rate in 2026?
Delaware withholds the aggregate method on a separately paid bonus, on top of the flat 22% federal rate (37% above $1,000,000/yr) and 7.65% FICA. That's withholding, not your final tax. Delaware also withholds paid family leave contributions from wages, which this estimate does not model.
Does Delaware have a separate bonus withholding rate?
No. Delaware has no separate supplemental rate, so a bonus is withheld with the aggregate method — as if it were part of your regular wages.
