How it works
Your paycheck shrinks through: federal income tax (bracket-based), FICA (7.65% for Social Security + Medicare), state tax (varies), and pre-tax deductions like 401(k) and health insurance.
Pre-tax deductions are powerful: $5,000 into a 401(k) costs you less than $5,000 of take-home pay because it skips income tax.
Frequently asked questions
What is FICA?
7.65% total: 6.2% Social Security (on first $176,100 in 2025) + 1.45% Medicare. Your employer matches it.
Why is my bonus taxed more?
Bonuses are often withheld at a flat 22% federal — usually more than your normal rate. You get the difference back at tax time.
How can I increase take-home?
Adjust W-4 withholding if you get big refunds, or raise pre-tax 401(k)/HSA contributions (lowers taxable income).
