Bonus tax questions
Why does flat federal withholding use 22%?
That is the lower supplemental wage rate used by this calculator. Withholding is a payment toward your annual tax bill; your salary, bonus and filing status determine how much federal income tax the bonus adds.
Does a bonus have a different final income-tax rate from salary?
Salary and bonuses both count as ordinary employment income for federal income tax. Employers can use a different method to withhold from a bonus, which can make the deduction on that payment look larger.
What might I keep from a $10,000 bonus?
For a single filer with a $75,000 annual salary and no earlier supplemental wages, the flat method estimates $2,200 in federal withholding and $765 in employee payroll taxes. That leaves $7,035 before state income tax; change the inputs above for your situation.
Which federal supplemental rates does the 2026 estimate use?
The flat method applies 22% until supplemental wages from this employer reach $1,000,000 for the year, then 37% to the excess. Enter earlier supplemental wages so the calculator can apply that threshold.
Why might my payroll result differ?
This estimate counts annual salary and earlier supplemental wages as already paid when applying payroll limits. Actual payment timing, payroll entries and state withholding can change the amount your employer deducts; the federal filing comparison shows a separate estimate of tax added by the bonus.
