Why Your Paycheck Is Smaller Than Your Salary
A $90,000 salary sounds like $7,500 a month — until $1,800+ disappears 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 are calculated, which lowers 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 is taxed at that bracket's rate. Earning into a higher bracket never reduces your take-home pay; the lower brackets still apply to the 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 the 7.65% — it's part of your compensation you never see.
4. State (and local) income tax
Ranges from 0% (Texas, Florida, Washington, and six others) to over 13% (California's top bracket). Some cities add their own tax. This is the single biggest geographic swing in 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
| Item | Annual |
|---|---|
| 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 the salary never reaches the bank account — and this person is saving a reasonable 6% for retirement. In Texas (no state income tax), the same salary nets roughly $5,000 more per year.
Why bonuses feel over-taxed
Bonuses are withheld at a flat 22% federal supplemental rate — often above your regular withholding rate — but they're taxed at your normal marginal rate. The difference washes out when you file; you weren't actually taxed more, just withheld more.
Three legitimate ways to raise take-home pay
- Fix over-withholding. Big annual refund? That's an interest-free loan to the IRS. Adjust your W-4 to keep more per paycheck.
- Prefer pre-tax contributions when choosing between traditional and Roth, if current cash flow is the constraint — pre-tax dollars cost you less out-of-pocket today.
- Know your state's bite. Moving from a 9% state to a 0% state is an instant raise with no negotiation required.

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.
