Estimated net bonus:
Gross payment − all entered taxes and deductions
Use figures from your payroll department or a recent paycheck. Enter zero if an item does not apply.
For example, Florida, Nevada and Texas do not impose an individual state income tax, although local rules and your payroll circumstances may still affect the payment. The explanation below identifies what the calculator includes.
What Does the Result Mean?
The result is an estimate of the amount left after subtracting the figures you provide.
A small difference may result from rounding. A moderate difference may reflect payroll settings.
A large difference may occur if the employer applies different supplemental wage or state rules. Withheld amounts count toward annual obligations, but they do not necessarily represent your final tax liability.
Your filing result depends on your annual income, deductions, credits and other financial information.
The calculator excludes employer-paid Federal Unemployment Tax Act (FUTA) amounts because FUTA generally does not reduce an employee’s wages. A calculator based on employee deductions should exclude these employer-paid amounts.
Check the calculation method before relying on the estimate.
How Is the Bonus Estimate Calculated?
The calculator uses a subtraction method: net pay equals gross supplemental pay minus every employee tax amount and deduction entered.
Employers may process the payment using a separate supplemental wage method or an aggregate method. Under the aggregate method, the employer combines the bonus with regular wages and calculates withholding on the combined paycheck.
Payroll then accounts for the amounts associated with regular wages. The selected method can change the paycheck amount even when the employee’s eventual taxes remain unchanged.
Formula:
Net bonus = gross bonus − federal tax − Social Security − Medicare − state and local tax − other deductions
This calculator was reviewed on August 8, 2026. It does not automatically determine current federal or state rates, wage limits or employee elections.
Verify date-sensitive information with the Internal Revenue Service (IRS), the responsible state revenue agency and your employer. The worked example below shows how to apply the method.
Worked Example
This bonus example shows every amount entered, so you can check the calculation.
Assume an employee receives a $2,000 bonus. Their payroll record shows $440 of federal tax, $124 of Social Security, $29 of Medicare, $100 of state taxes and no other deductions.
$2,000 − $440 − $124 − $29 − $100 = $1,307
The estimated net bonus is $1,307. These figures illustrate the calculation only; they are not current rates or a recommendation for any state.
If payroll uses the aggregate method, the actual paycheck may differ. The FAQs explain what to check next.
Bonus Calculator FAQs
These answers cover accuracy, assumptions, privacy and the next practical step.
Is this estimate accurate?
The bonus estimate is only as accurate as the information entered. If your employer has not confirmed the method, compare low, middle and high tax estimates.
Are bonuses taxed differently from regular wages?
A bonus is taxable compensation, but employers may calculate the amount withheld under supplemental wage procedures or the aggregate method. The withholding method does not determine your final tax liability.
Does the calculator store my information?
This page does not state that it stores, transmits or protects the information you enter. Review the site’s privacy notice, and do not enter identifiers such as a Social Security number.
What should I do after calculating my bonus?
Compare the estimate with your pay statement and ask your employer’s payroll department to confirm the applicable treatment. Then use the IRS estimator to review your overall federal withholding.
