Bonus Tax Withholding Calculator

The Bonus Tax Withholding Calculator clears up the difference between what gets withheld from a bonus check and what you actually owe at your real marginal rate. You enter the gross bonus, your federal bracket, your state rate, and which withholding method your employer uses. The calculator returns the take-home you see on payday, the true take-home after your real tax bill, and the additional amount you may owe in April if withholding fell short. Use it the day a bonus is announced. The flat 22 percent supplemental rate routinely under-withholds for higher earners, and not knowing the gap is the most common reason a tax refund turns into an unexpected April bill.
