A sign-on bonus is a one-time payment that employers offer new employees when they accept a job offer. It’s often used to attract top talent, compensate for relocation, or provide an incentive to join the company quickly. However, employees are often surprised when their sign-on bonus is lower than expected because of tax deductions and other withholdings.

What is a Sign-On Bonus?
A sign-on bonus is a financial incentive paid to a new employee when they accept a job offer. Companies use it for:
- Attracting skilled candidates in competitive industries.
- Offsetting relocation expenses.
- Compensating for benefits left behind at a previous job.
- Rewarding employees for quickly joining the company.
While the bonus amount might sound attractive, it’s important to remember that it is considered taxable income.
How the Sign On Bonus Calculator Works
Our calculator estimates your net sign-on bonus by factoring in:
- Gross bonus amount – The total amount offered by the employer.
- Federal tax rate – Usually between 22% and 37% depending on your income bracket.
- State tax (if applicable) – Some states tax bonuses, others don’t.
- Other deductions – Social Security, Medicare, or retirement contributions.
The result is your take-home sign-on bonus, which is the actual amount you’ll receive in your bank account.
Formula Used in Sign-On Bonus Calculation
To calculate the net sign-on bonus:
Net Bonus = Gross Bonus – (Federal Tax + State Tax + Other Deductions)
Where:
- Federal Tax = Gross Bonus × Federal Tax Rate
- State Tax = Gross Bonus × State Tax Rate
- Other Deductions = Gross Bonus × Additional Deductions %
Example of Sign-On Bonus Calculation
Let’s say:
- Gross Sign-On Bonus = $10,000
- Federal Tax Rate = 22%
- State Tax Rate = 5%
- Other Deductions = 7.65% (Social Security + Medicare)
Step 1: Federal Tax = $10,000 × 22% = $2,200
Step 2: State Tax = $10,000 × 5% = $500
Step 3: Other Deductions = $10,000 × 7.65% = $765
Net Bonus = $10,000 – ($2,200 + $500 + $765) = $6,535
So, from a $10,000 sign-on bonus, the employee will actually take home about $6,535.
