The layers of tax on a paycheck
Every paycheck goes through the same layers. Some are fixed percentages; others depend on your W-4, your state and where you live.
| Layer | Who pays | Typical share of gross pay |
|---|---|---|
| Federal income tax | Everyone with taxable income | Depends on pay and W-4; about 8.4% on a $60,000 single salary |
| Social Security | Almost all employees | 6.2% up to $184,500 |
| Medicare | Almost all employees | 1.45% (2.35% on wages over $200,000) |
| State income tax | 41 states and D.C. | 0% in nine states; roughly 2–5% in many others |
| State payroll taxes | Some states (SDI, paid leave) | Usually under 1.5% |
| Local income tax | Some cities, counties, school districts | Often 0.5% to 4% where it applies |
1. Federal income tax
This is the most variable line. Your employer annualizes your pay and subtracts an amount that, together with the zero-rate band built into the IRS tables, equals the 2026 standard deduction: $16,100 single, $32,200 married filing jointly, $24,150 head of household. It then applies the tax brackets (10%, 12%, 22%, 24%, 32%, 35% and 37%) and divides the result by your number of paychecks. Your W-4 changes this: Step 3 credits lower it, Step 4(c) extra withholding raises it.
2. Social Security and Medicare (FICA)
These are flat: 6.2% and 1.45%, together 7.65%. Social Security stops for the year once one employer has paid you $184,500. Medicare never stops, and an extra 0.9% starts above $200,000. Details are in our FICA guide.
3. State income tax
Nine states don’t tax wages (see states with no income tax). Others use a flat rate, such as Pennsylvania at 3.07%, North Carolina at 3.99% and Illinois at 4.95% in 2026, or graduated brackets.
4. State payroll taxes
Disability and family leave programs take a small slice in some states. For example, California SDI is 1.3% in 2026, and Washington’s paid leave premium is about 0.81% plus 0.58% for WA Cares.
5. Local income tax
Some cities, counties and school districts tax wages too. Examples include New York City (residents), Philadelphia, Detroit, Ohio cities, Maryland counties and Pennsylvania municipalities.
Worked example: $60,000 a year in Texas, paid biweekly
Assumptions: single, 2026 Form W-4 with no adjustments, no pre-tax deductions, Texas (no state or local income tax). The numbers come from our calculator’s engine.
| Per paycheck | Per year | |
|---|---|---|
| Gross pay | $2,307.69 | $60,000 |
| Federal income tax | $193.08 | $5,020 |
| Social Security (6.2%) | $143.08 | $3,720 |
| Medicare (1.45%) | $33.46 | $870 |
| State income tax | $0.00 | $0 |
| Take-home pay | $1,938.07 | $50,390 |
Total taxes are about $9,610 a year, 16.0% of gross pay. The yearly figures are rounded to the dollar; each check is rounded to the cent.
How the federal amount is figured
- Annualize: $2,307.69 × 26 = $59,999.94.
- Subtract the standard deduction: $16,100 leaves $43,899.94 of taxable income.
- Apply the brackets: 10% on the first $12,400 = $1,240. Then 12% on the remaining $31,499.94 = $3,779.99. Total $5,019.99.
- Divide by 26: $193.08 per paycheck.
The marginal rate is 12%, but the average federal rate is only about 8.4%. That’s why a raise never lowers your take-home pay: only the extra dollars are taxed at the higher rate. The pay raise calculator shows how much of a raise you keep.
The same salary with a 401(k) and health insurance
If the same person puts 5% into a traditional 401(k) ($115.38 per check) and pays $100 per check in pre-tax health premiums:
| Per paycheck | |
|---|---|
| Federal income tax | $167.23 (down $25.85) |
| Social Security | $136.88 (down $6.20) |
| Medicare | $32.01 (down $1.45) |
| Take-home pay | $1,756.19 |
$215.38 goes to the 401(k) and health plan, but take-home pay falls by only $181.88, because those dollars aren’t taxed. The health premium lowers FICA too; the 401(k) doesn’t (see the 401(k) paycheck calculator).
Why your numbers may differ
- Your W-4 entries. Dependents, other income, deductions, the Step 2 checkbox or extra withholding all change federal tax.
- Pay frequency. Weekly, biweekly, semi-monthly and monthly checks are different sizes, but the yearly totals barely change.
- Bonuses. Supplemental pay is often withheld at a flat 22% federal rate.
- State and city. State tax, state payroll programs and local tax can add several percent.
- Year-to-date wages. Social Security stops once you pass $184,500 with one employer.
How to see your own numbers
- Open the paycheck calculator and pick your state.
- Enter your salary or hourly rate and pay frequency.
- Enter your W-4 exactly as filed. Check your latest pay stub if you’re unsure (our pay stub guide explains each line).
- Add pre-tax deductions such as 401(k), health insurance or HSA.
Compare the result with your actual stub. If federal withholding is far off, your employer may have an old W-4 on file.
