Take-Home Pay: What Your Salary Actually Pays You (2026)

The offer letter says $100,000. The paycheck says otherwise, and the gap is not a mystery — it is a list. Understanding the list is worth more than complaining about it, because every line on it is a decision you can change.

For a single filer with no state income tax, a $100,000 salary takes home about $79,000 a year — roughly $6,580 a month on 12 pays — after federal income tax of about $13,400 and FICA of $7,650. Add state tax, health benefits, and a 401(k), and the real number drops further. The gross-to-net pay calculator runs your exact payroll with the rates you enter.

The paycheck anatomy

Every paystub is the same stack:

1. Gross pay — your salary or hourly earnings before anything.
2. Federal income tax — withheld according to your W-4, not your tax bracket. Your bracket is decided at filing; withholding is your estimate.
3. FICA — 7.65% split between Social Security (6.2%, up to the wage cap) and Medicare (1.45%, no cap, plus 0.9% above $200,000 for single filers).
4. State and local tax — varies from zero (Texas, Florida) to over 13% top rates (California), and it is a real line on the paycheck.
5. Your elections — health insurance, 401(k), HSA, FSA, and everything else you signed up for.

The 2026 federal numbers

• Standard deduction: $16,100 single, $24,150 head of household, $32,200 married filing jointly. This is the floor every itemization decision measures against.
• Rates: the federal brackets run 10% to 37%, and they are marginal — each bracket applies only to the income inside it.
• FICA: 7.65% on wages, with the Social Security cap around $180,000 in 2026.

The 2026 updates are covered in the site's 2026 tax changes guide. What matters for take-home: the standard deduction is the reason a $100,000 salary pays about 13% effective federal income tax, not 22%.

The worked example

$100,000, single filer, no state tax:

Now add the choices: a 6% 401(k) contribution ($6,000) costs about $4,700 of take-home — the tax deduction pays part of the bill. Health insurance at $300 a month is the full $3,600. State tax, where it exists, takes another slice. Run each line through the gross-to-net calculator with your real rates and benefits, and compare the result against your paystub — the difference between the two is usually a missing line, and finding it is the point.

The two ways to change the number

• Pre-tax elections. A 401(k), HSA, and health premiums lower taxable income, so they cost less than their face value in take-home. An HSA is triple-taxed in your favor: pre-tax in, tax-free growth, tax-free out for medical costs.
• Withholding accuracy. If your W-4 is wrong, the IRS is running a free loan on your money or handing you a bill in April. The W-2 withholding fix guide covers the mid-year correction, and the payroll withholding calculator prices the adjustment.

If your income is uneven — bonuses, side income, a business — the self-employment tax reserve calculator handles the quarterly side, and the tax calculators cover the rest of the payroll stack.

Bottom line

Take-home pay is gross minus a short list, and every line on the list is a decision. Know the standard deduction, watch the FICA line, and make your pre-tax elections deliberately. The gross-to-net pay calculator turns your salary into your real number in one pass.
