How Much Is My Take-Home Pay After Benefits? (2026)
Take-home pay = gross pay − pre-tax deductions − taxes − after-tax deductions. The order matters because pre-tax benefits shrink the income that gets taxed.
What comes out, in order
- Section 125 deductions (health/dental/vision premiums, HSA, FSA): reduce federal, FICA and usually state taxable wages.
- Traditional 401(k): reduces income tax, but not Social Security and Medicare.
- Federal income tax: 2026 brackets after the standard deduction ($16,100 single, $32,200 married filing jointly, $24,150 head of household).
- FICA: 6.2% Social Security up to $184,500 of wages, plus 1.45% Medicare (+0.9% over $200,000 single).
- State and local tax: from 0% (TX, FL, WA…) to over 10% at the top in CA and NY.
- After-tax deductions: Roth 401(k), supplemental life, union dues.
Worked example: $60,000 single in Texas
No benefits: taxable income $43,900 → federal tax $5,020; FICA $4,590; take-home ≈ $50,390 a year, $1,938 every two weeks.
Add a 5% 401(k) ($3,000) and $546/yr premium: federal tax drops by about $425 and FICA by about $42, so take-home falls by only ~$3,080 even though $3,546 went to your future and health coverage.
Why a raise can feel small
Your marginal rate (the tax on your next dollar) can be 30%+ with FICA and state tax, while your effective rate is much lower. Know both before deciding how much to put pre-tax.
FAQ
Do health premiums reduce my taxes?
Yes, when deducted through a Section 125 cafeteria plan, which is how most employers do it. They reduce federal income tax, Social Security, Medicare and usually state tax.
Does a 401(k) reduce Social Security tax?
No. Traditional 401(k) contributions reduce income tax but are still subject to Social Security and Medicare.
