Bonus Tax Calculator — Take-Home on Your Bonus

See exactly how much of your bonus you keep after federal withholding, state tax, and FICA — and whether you will owe more at tax time. No surprises come April.

Quick answer: Bonus withholding is not always your final bonus tax. Compare supplemental withholding, regular income tax, state tax, and FICA to estimate whether you may owe more or get a refund.

Frequently Asked Questions

Everything you need to know.

Why is so much taken out of my bonus?
Bonuses are withheld at a flat 22% federal rate (regardless of your bracket), plus state income tax, plus 6.2% Social Security (until you cross the wage base), plus 1.45% Medicare, plus an extra 0.9% Medicare if your total income crosses $200K. The result: most bonuses see 35-45% withheld at the moment of deposit.
Will I get some back at tax time?
Depends on your bracket. If your marginal federal rate is 22% or below, the flat 22% withholding fully covers your liability — and you may even get a small refund. If you are in the 24%, 32%, 35%, or 37% bracket, you owe additional tax at filing time. The 'True-Up at Tax Time' row above shows the exact amount.
Should I adjust my W-4 to cover the shortfall?
Yes, if you would rather not write a check in April. Add an additional fixed-dollar withholding on your W-4 each pay period — divide the shortfall by remaining paychecks. Alternatively, park the shortfall in a HYSA earning 4-5% APY and pay it when due. Either approach is fine; just do not ignore it.
Is the Bonus Tax Calculator — Take-Home on Your Bonus free to use?
Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.
Does using the Bonus Tax Calculator — Take-Home on Your Bonus affect my credit score?
No. Using a calculator does not trigger a credit check. A credit impact can occur only if you apply directly with a lender, card issuer, or provider.
Are the results personalized financial advice?
No. Calculator outputs are educational estimates based on the inputs you enter. Review assumptions and confirm terms directly with providers before making a financial decision.
What should I do after seeing the result?
Use the recommendation module on this page to park your tax reserve in a high-yield account, or run Money Map to compare this banking & savings decision with your other opportunities.
How does SwitchWize choose related offers?
Related offers are matched by the calculator surface (savings) and ranked using SwitchWize data such as rate, fees, trust signals, product fit, and switching friction. Paid relationships do not change organic ranking order.
How fresh are the rates and offers shown?
Rate and offer data is reviewed on a recurring cadence and every offer module shows review context or links to the methodology and disclosure pages.
Where can I see the ranking methodology?
The SwitchWize methodology page explains how rate freshness, editorial review, affiliate disclosure, and category ranking factors work.
Can Money Map use this result?
Yes. Money Map is the broader diagnostic path: it compares savings, mortgage, cards, and debt so you can see whether this calculator result is your highest-impact next move.

Why This Matters

Bonuses feel like found money until you see the deposit. The IRS treats bonuses as supplemental wages with a flat 22% federal withholding (37% above $1M). If you are in a higher bracket, that withholding falls short of your actual liability — and you owe the difference at tax time. The first ~$15,000 of a six-figure bonus often disappears before you see it. Knowing the math up-front lets you plan.
