Why Your Paycheck Is Smaller Than Your Salary

A $90,000 salary sounds like $7,500 a month. Then $1,800+ vanishes before payday. Here's exactly where every withheld dollar goes, in the order it leaves.

Key takeaways

  • A $90,000 salary is $7,500/month gross — but $1,800+ disappears before payday.
  • Deductions leave in a fixed order: federal income tax, Social Security and Medicare (FICA), state tax, then benefits and retirement contributions.
  • Bonuses feel over-taxed because they're withheld at a flat supplemental rate, not your marginal bracket.
  • Includes a worked example: $90,000 in California, single filer.

The deductions, in order

1. Pre-tax deductions (reduce taxable income)

These come out before taxes get calculated, which shrinks your tax bill:

  • Traditional 401(k) / 403(b) contributions
  • HSA contributions (triple tax advantage)
  • Health, dental, and vision insurance premiums
  • FSA contributions

2. Federal income tax

The U.S. uses marginal brackets: only the income inside each bracket gets taxed at that bracket's rate. Moving into a higher bracket never shrinks your take-home pay. The lower brackets still cover your first dollars. For 2026, brackets start at 10% and top out at 37%.

3. FICA: Social Security + Medicare

  • Social Security: 6.2% on wages up to the annual cap ($184,500 for 2026)
  • Medicare: 1.45% on all wages, plus an extra 0.9% above $200,000

Your employer matches that 7.65%. It's part of your pay you never see on a stub.

4. State (and local) income tax

State income tax runs from 0% (Texas, Florida, Washington, and six others) all the way past 13% (California's top bracket). Some cities pile on their own tax. This is the single biggest geographic swing in your take-home pay.

5. Post-tax deductions

  • Roth 401(k) contributions (taxed now, tax-free later)
  • Disability or supplemental life insurance
  • Wage garnishments, union dues

Worked example: $90,000 in California, single

ItemAnnual
Gross salary$90,000
401(k) (6% pre-tax)−$5,400
Health insurance premiums−$2,400
Federal income tax−$10,100
FICA (7.65%)−$6,885
California income tax−$5,300
Take-home pay≈ $59,900
Per biweekly paycheck≈ $2,304

About one-third of this salary never touches the bank account. And that's with a sensible 6% going to retirement. Same salary in Texas, with no state income tax? Roughly $5,000 more per year in your pocket.

Your marginal dollar is taxed harder than your average dollar. If your top bracket is 22% federal + 7.65% FICA + 5% state, a $1,000 raise nets you only about $653. Useful to know before negotiating. And before assuming a raise solves a budget gap.

Why bonuses feel over-taxed

Bonuses get withheld at a flat 22% federal supplemental rate, often above your normal withholding. But they're taxed at your regular marginal rate, like the rest of your pay. The difference washes out at tax time. You weren't taxed more. You were just withheld more.

Three legitimate ways to raise take-home pay

  1. Fix over-withholding. Big annual refund? Congratulations, you gave the IRS an interest-free loan. Adjust your W-4 and keep more in each paycheck.
  2. Prefer pre-tax contributions when you're choosing between traditional and Roth and cash flow is tight. Pre-tax dollars cost you less out of pocket today.
  3. Know your state's bite. Moving from a 9% state to a 0% state is an instant raise. No negotiation required.

Frequently asked questions

What is taken out of my paycheck?

Federal income tax, FICA (Social Security + Medicare), state/local tax, pre-tax deductions like 401(k) and health premiums, and post-tax deductions like Roth contributions.

What is FICA?

7.65% total — 6.2% Social Security (up to the wage cap) plus 1.45% Medicare. Your employer matches it.

Why was my bonus taxed so much?

It was withheld at 22% federal, not taxed at 22%. Your actual tax rate on it matches your marginal bracket; the difference settles at filing time.

Pre-tax or Roth 401(k)?

Pre-tax lowers today's taxable income (bigger paycheck now); Roth costs more today but withdrawals are tax-free in retirement. High earners now often favor pre-tax; young low earners often favor Roth.

How can I increase my take-home pay without a raise?

Correct W-4 over-withholding, shift to pre-tax contributions, and factor state taxes into where you live.
