Use the free Bonus Tax Calculator on ToolVexa to estimate the tax withheld from a bonus and the net bonus left after federal and state withholding.
How to Use
Enter the bonus amount and the federal and state withholding rates as percentages, then press Calculate.
Formula in Plain Words
Add the two withholding rates together, apply that combined rate to the bonus to get the tax withheld, then subtract the tax from the bonus to get the net bonus.
Worked Example
With a $5,000 bonus, a 22% federal rate and a 5% state rate, tax withheld is $5,000 x 27% = $1,350, so the net bonus is $3,650.
FAQs
Is this the exact tax on my bonus?
No. It is an estimate based only on the two rates you enter; actual withholding can include other items.
Why might bonus withholding differ from regular pay?
Bonuses are often withheld at a flat supplemental rate rather than the rate used for regular wages.
Can the combined rate be over 100%?
Enter realistic rates; if the combined rate exceeds 100%, the calculator will show a negative net bonus, which means the rates need checking.
