Question 1

Is a bonus taxed higher in Delaware?

Accepted Answer

No. Delaware taxes a bonus as ordinary wages on your return, at the same rates as your salary. Withholding can look high because the employer applies the annualized method for DE on top of the 22% federal flat rate and 7.65% Social Security and Medicare. Any difference between what was withheld and what you owe is settled when you file.

Question 2

What rate does Delaware withhold on bonuses in 2026?

Accepted Answer

Delaware has no flat bonus rate. For a bonus paid separately, the employer annualizes your regular wages, computes the yearly tax with and without the bonus, and withholds the difference. In practice the bonus is withheld at your top Delaware bracket, up to 6.6%.

A bonus paid together with regular wages is treated as one payment and withheld from the regular tables.

Question 3

Can I reduce the withholding on my Delaware bonus?

Accepted Answer

The most direct way is a 401(k) deferral from the bonus, if your plan allows it: the deferred part is not subject to federal income tax withholding or DE income tax withholding. When your employer uses the flat 22% federal rate, your Form W-4 does not change it; under the aggregate method it does. If you expect a large refund or bill, adjust your W-4 for the rest of the year rather than the bonus itself.

Question 4

Why was so much taken out of my bonus?

Accepted Answer

A bonus check usually loses 22% to federal income tax withholding, 7.65% to Social Security and Medicare, and your state's supplemental rate on top. That can add up to 30% to 40% of the bonus. The federal 22% and the state rate are withholding, not a separate bonus tax. When you file your return, the bonus is taxed as ordinary wages at your real bracket, and any over-withholding comes back as a refund.

Question 5

What is the federal bonus tax rate in 2026?

Accepted Answer

There is no separate federal bonus tax. For withholding, IRS Publication 15 (2026) lets employers withhold a flat 22% on supplemental wages such as bonuses and commissions, or add the bonus to a regular paycheck and use the normal tables (the aggregate method). Supplemental wages above $1 million in a calendar year must be withheld at 37%. Social Security (6.2% up to the $184,500 wage base) and Medicare (1.45%, plus 0.9% on wages above $200,000) apply as well.

Question 6

Does putting my bonus in a 401(k) lower the tax?

Accepted Answer

Yes, if your plan allows deferrals from bonuses. A traditional 401(k) deferral is not subject to federal income tax withholding, so the 22% applies only to the part you take as cash. Social Security and Medicare still apply to the full bonus. The 2026 employee deferral limit is $24,500 across all your paychecks, including any deferrals you already made this year.
