Calculate bonus after tax in 2026 with federal withholding, FICA, supported state tax, local tax, and paycheck deduction assumptions.
Calculate bonus after tax
Use this bonus tax calculator for a quick 2026 estimate of a supplemental paycheck after federal withholding, Social Security, Medicare, Additional Medicare when applicable, supported state tax, optional local tax, and paycheck deductions. For separately identified supplemental wages, the calculator uses the 2026 IRS flat federal rate of 22% up to $1 million and 37% on supplemental wages above $1 million. The final tax return can still reconcile the actual federal income tax owed.
What is included
The estimate includes federal income tax withholding, Social Security, Medicare, Additional Medicare where applicable, supported state tax, optional local tax inputs, W-4 adjustments, pre-tax deductions, and post-tax deductions. State pages show whether a state is enhanced, basic, no-income-tax, or still pending verified withholding support.
How to calculate bonus after tax in 2026
Enter the bonus amount, state, filing status, and any extra W-4 or deduction inputs. The calculator estimates the bonus paycheck after federal supplemental withholding, Social Security, Medicare, Additional Medicare when applicable, supported state tax, local tax, and post-tax deductions.
With the default $5,000 Texas bonus example, estimated take-home bonus pay is $3,518. States with income tax, local wage tax, SDI, or paid leave programs can produce a lower net bonus from the same gross amount.
2026 supplemental bonus tax rate
IRS Publication 15 says bonuses are supplemental wages. For a separately identified bonus paid after regular wage withholding, the 2026 federal supplemental withholding rate is 22.0% up to $1,000,000 of supplemental wages for the year. Amounts above that threshold are withheld at 37.0%. Social Security, Medicare, state tax, local tax, and deductions can still apply.

| Federal supplemental rate | 22.0% flat withholding on separately identified supplemental wages up to $1,000,000. |
| High supplemental wages | 37.0% withholding on supplemental wages above $1,000,000. |
| Combined wage method | If an employer combines bonus and regular wages, payroll may use the aggregate method instead of the flat rate. |
Bonus withholding vs final tax
A bonus is commonly treated as supplemental wages for payroll withholding. This page is a paycheck withholding estimate, not a final tax return calculator, so the amount withheld from a bonus can differ from the final tax owed after all annual income, credits, deductions, and other payments are reconciled.
