What This Calculator Does
This bonus tax calculator estimates the federal taxes withheld from your bonus and shows your net payout. The IRS classifies bonuses as "supplemental wages," which are subject to a flat 22% federal withholding rate — different from how your regular salary is withheld.
How It Works
- Federal withholding — flat 22% on bonuses up to $1 million (IRS "percentage method")
- Social Security — 6.2% on bonus amount (subject to annual wage base cap)
- Medicare — 1.45% on all bonus income
- Annual salary — used to determine whether you've hit the Social Security wage base ($176,100 for 2026)
Example Calculation
A $5,000 bonus with a $75,000 base salary would be withheld as follows:
- Federal (22%): $1,100
- Social Security (6.2%): $310
- Medicare (1.45%): $72.50
- Total withheld: $1,482.50
- Net bonus received: $3,517.50
Why This Matters
Employees are often surprised when a $5,000 bonus nets only $3,500. Knowing the actual payout in advance helps you plan — whether you're deciding how much to put toward debt, savings, or a major purchase. It also helps you verify your employer is withholding the correct amount.
