Federal taxes, FICA & 401(k) deductions
Most American workers are surprised the first time they see the gap between their gross salary and their actual take-home pay. On a $75,000 annual salary paid bi-weekly, the gross paycheck is $2,884. Federal income tax withholding at the 22% marginal rate (using 2026 brackets and the $15,000 standard deduction for single filers) takes roughly $380–$420. Social Security takes 6.2% ($179) and Medicare takes 1.45% ($42). That's $601–$641 in federal deductions before state income tax, health insurance premiums, or retirement contributions. States like California, New York, and Illinois add another 3%–8% in state income tax on top of that.
The 401(k) deduction deserves special attention because it reduces federal income tax withholding as well as your net paycheck. Contributing 6% of a $75,000 salary ($4,500/year, $173 bi-weekly) reduces your taxable wages by that amount. At the 22% marginal rate, that $173 pre-tax contribution only actually costs you about $135 in take-home pay — the federal withholding calculator adjusts automatically. This makes 401(k) contributions especially efficient: you put in $173 gross but your paycheck only drops $135, because the government essentially subsidizes 22% of your retirement contribution through lower tax withholding.
The IRS uses 2026 tax brackets (10%, 12%, 22%, 24%, 32%, 35%, 37%) to determine withholding. Single filers get a $15,000 standard deduction. Most workers earning $45,000–$100,000 pay an effective federal rate of 12%–18%.
Employee Social Security tax is 6.2% of wages up to the 2026 wage base of $184,500. Self-employed workers pay the full 12.4% themselves. Once you earn above $184,500, Social Security tax stops for the rest of the year.
Medicare tax is 1.45% of all wages with no cap. High earners (above $200,000 single / $250,000 married) pay an additional 0.9% Additional Medicare Tax. Combined with the employer share, Medicare receives 2.9% on every dollar earned.
Pre-tax 401(k) contributions reduce your taxable income dollar-for-dollar. A $500/month 401(k) contribution at a 22% marginal rate only reduces take-home pay by $390 — the IRS effectively contributes $110 through reduced withholding.
