When to use this calculator
Use this bonus tax calculator to estimate how much of a bonus may remain after withholding. It is useful for planning before spending, saving or investing a bonus.
Formula
Net bonus = gross bonus x (1 - withholding rate)
- Gross bonus is the bonus amount before withholding.
- Withholding rate estimates tax and deductions taken from the bonus.
- Net bonus is the simplified take-home estimate.
Worked example
For a $10,000 bonus and 35% withholding rate, the calculator estimates $3,500 withheld and $6,500 net bonus pay.
Common mistakes
- Assuming withholding equals final tax owed.
- Forgetting retirement contributions or benefit deductions.
- Planning to spend the gross bonus instead of the net amount.
FAQs
Is bonus withholding the same as final tax?
No. Withholding is an estimate or payroll method; final tax depends on your full-year tax return.
Why is my bonus taxed heavily?
Bonuses may be withheld at supplemental or higher estimated rates depending on payroll rules.
Can I use this for commissions?
Yes, as a rough withholding estimate if you enter the expected gross amount and withholding rate.
