Understanding Your Paycheck
What Gets Deducted from Your Paycheck?
Your gross salary is not what you take home. Several mandatory and voluntary deductions reduce your paycheck:
1. Federal Income Tax
Based on your income, filing status, and W-4 allowances. Uses the 2024 federal tax brackets (10-37%). Your employer withholds an estimated amount each pay period.
2. FICA Taxes (Social Security & Medicare)
- Social Security: 6.2% up to $160,200 wage base (2024)
- Medicare: 1.45% on all wages
- Additional Medicare: 0.9% on income over $200,000 (single)
- Total FICA: 7.65% for most employees
3. State Income Tax
Varies by state. Nine states have no income tax:
- Alaska, Florida, Nevada, New Hampshire
- South Dakota, Tennessee, Texas, Washington, Wyoming
Highest state income tax rates (2024):
- California: 13.3%
- New York: 10.9%
- New Jersey: 10.75%
- Hawaii: 11%
4. 401(k) Contributions
- 2024 Limit: $23,000 ($30,500 if age 50+)
- Tax Benefit: Reduces taxable income (pre-tax contributions)
- Employer Match: Free money - always contribute enough to get full match
- Roth 401(k): After-tax contributions, tax-free withdrawals in retirement

Bi-Weekly Advantage
How to Optimize Your W-4
Your W-4 form determines how much federal tax is withheld from your paycheck. Changes in 2020 eliminated allowances and use a more accurate system.
- Claim Dependents: Reduces withholding if you have qualifying children
- Multiple Jobs: Use IRS worksheet to avoid under-withholding
- Extra Withholding: Add amount if you expect to owe taxes
- Reduce Withholding: If you consistently get large refunds
💡 Smart Strategy
Getting a large tax refund means you gave the IRS an interest-free loan all year. Adjust your W-4 to keep more money in your paycheck and invest it throughout the year instead.
