Select Filing Status: Choose between Single, Married Filing Jointly, or Head of Household.

Gross Bonus: The total bonus amount you entered.
Federal Withholding: The federal taxes withheld based on your chosen method.
Social Security: The 6.2% Social Security tax withheld (up to a certain limit).
Medicare: The standard 1.45% Medicare tax.
Additional Medicare: An additional 0.9% Medicare tax for high earners.
State and Local Withholding: Calculations based on the state and local tax rates you provided.
Total Withholding: The total amount withheld in federal, state, and local taxes.
Net Bonus: The actual amount you’ll take home after all deductions.

Example of How It Works

Imagine you’re an employee with a $10,000 bonus. You live in a state with a 5% tax rate and a local tax rate of 2%. You’re filing as “Single” and your annual salary is $50,000.

Federal Withholding (Percentage Method): 22% of $10,000 = $2,200
Social Security (6.2%): If your annual salary is below the wage base, 6.2% of $10,000 = $620
Medicare (1.45%): 1.45% of $10,000 = $145
State Withholding (5%): 5% of $10,000 = $500
Local Withholding (2%): 2% of $10,000 = $200

The total amount withheld would be $3,665, leaving you with a net bonus of $6,335.
