ADP Bonus Paycheck Calculator
Receiving a bonus from your employer can be exciting, but many employees are surprised when the actual amount they receive is much lower than expected. This happens because bonuses are typically treated as supplemental wages and are subject to several taxes and deductions.

This calculator provides a clear estimate of:
- Federal income tax withholding
- State income tax withholding
- Social Security tax
- Medicare tax
- 401(k) or retirement contributions
- Other deductions

With this information, you can better understand how bonuses are taxed and plan your finances accordingly.
How Bonuses Are Taxed
Bonuses are considered supplemental wages by the IRS. Unlike regular wages, they are often taxed using specific withholding methods that can affect how much tax is deducted upfront.
Employers commonly use one of two methods when withholding taxes from bonus payments.
Bonus Withholding Methods
1. Percentage Method (Flat Rate)
The percentage method applies a flat federal withholding rate to bonus payments.
Currently, the IRS requires employers to withhold 22% federal tax on supplemental wages under $1 million.
For bonuses over $1 million, the federal withholding rate increases to 37%.
This method is simple and commonly used by payroll systems.
2. Aggregate Method
Under the aggregate method, the employer combines your bonus with your regular wages for the pay period and calculates taxes using your standard withholding rate.
This method may result in:
- Higher withholding
- Lower withholding
- More accurate withholding based on your tax bracket
The result depends on your overall income and payroll calculations.
Taxes That Apply to Bonuses
Several taxes may apply when you receive a bonus.
Federal Income Tax
Federal income tax is typically withheld at 22% when using the percentage method.
However, your actual tax liability may differ depending on your annual income and tax bracket.
State Income Tax
Many states also tax bonus income. The rate varies depending on where you live.
Some states have flat tax rates, while others have progressive tax systems.
Social Security Tax
Bonus income is subject to Social Security tax, which is currently 6.2% for employees, up to the annual wage base limit.
Medicare Tax
Bonuses are also subject to Medicare tax, which is 1.45% for most employees.
High-income earners may also be subject to an additional Medicare tax.
Retirement Contributions
If your employer allows 401(k) or retirement contributions from bonus payments, part of the bonus may be automatically invested into your retirement account.
This can reduce your taxable income, depending on the type of retirement plan.
Other Deductions
Some bonuses may also include additional deductions, such as:
- Health insurance premiums
- Benefit contributions
- Garnishments
- Voluntary payroll deductions
These deductions further reduce your final take-home bonus.
How the ADP Bonus Paycheck Calculator Works
The calculator estimates your net bonus paycheck by applying the selected tax rates and deductions to your gross bonus amount.
It calculates:
- Retirement contribution (if applicable)
- Taxable bonus amount
- Federal tax withholding
- State tax withholding
- Social Security tax
- Medicare tax
- Other deductions
Then it subtracts the total deductions from your bonus to determine the net bonus you receive.

Example Bonus Calculation
Here is an example showing how the calculator works.
Example Scenario
- Bonus Amount: $5,000
- Federal Tax (22%)
- State Tax: 5%
- Social Security: 6.2%
- Medicare: 1.45%
- 401(k) Contribution: 5%
- Other Deductions: $0
Step-by-Step Breakdown
401(k) Contribution
$5,000 × 5% = $250
Taxable Bonus After Retirement Contribution
$5,000 − $250 = $4,750
Federal Tax
$4,750 × 22% = $1,045
State Tax
$4,750 × 5% = $237.50
Social Security Tax
$4,750 × 6.2% = $294.50
Medicare Tax
$4,750 × 1.45% = $68.88
Total Deductions
$1,045 + $237.50 + $294.50 + $68.88 + $250
= $1,895.88
Net Bonus Paycheck
$5,000 − $1,895.88 = $3,104.12
This example shows how taxes and deductions can significantly reduce the amount you take home.
